Religious Riders and the Sherman Act

Can corporations engage in anticompetitive behavior on the basis of religious belief? While the answer may seem like an obvious no, in fact this question has largely been overlooked. It has hovered at the margins of the debate over religious exemptions: Proponents of religious exemptions have essentially argued that there is no harm in providing such exemptions to businesses because a competitive market will ensure consumers who might be denied services or goods by a religious firm can still obtain those goods and services elsewhere. But what if religiously minded businesses act in ways that are specifically designed to limit access to certain goods and services not just with respect to their own businesses but other businesses as well?

In this Article, I apply an antitrust lens to Catholic hospitals’ practice of imposing religious restrictions on secular, competitor collaborators, as well as post-sale religious restrictions on the sale of Catholic hospitals to secular buyers. Although Catholic hospital stakeholders assert that these contractual arrangements are necessary to protect the Catholic healthcare mission, this Article shows that these arrangements are also anticompetitive. By requiring a secular firm to artificially suppress output, these agreements lead both to deadweight loss (in the form of a denial of care) and higher prices. And because there is no procompetitive justification for such market harms, these agreements violate Section 1 of the Sherman Act.

There is not, and there should not be, a religious exemption to the Sherman Act. Although religious liberty is a fundamental component of our democratic system, this Article argues that there must nonetheless be market limits to free exercise. Religious firms may enjoy a right to unilaterally refuse to provide certain goods or services on the basis of religious devotion, but they should not be permitted to enter into anticompetitive agreements that limit other market actors’ ability to fully compete in the market. Similarly, secular businesses should not be permitted to justify otherwise anticompetitive agreements on the basis of other firms’ religious beliefs.

Introduction

The facts of Burwell v. Hobby Lobby Stores, Inc. are well known.1See generally Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682 (2014). In response to the Affordable Care Act’s mandate that employers provide coverage for contraceptives in their employee health plans, the owners of Hobby Lobby sued, arguing that doing so would constitute a violation of their sincerely held religious beliefs. The Supreme Court agreed and held first, that for-profit corporations have religious liberty rights, and second, that the contraceptive mandate violated the Religious Freedom Restoration Act (RFRA) because it substantially burdened the plaintiffs’ exercise of religion and did not satisfy RFRA’s least-restrictive-means requirement.
But what if the facts had been just a little bit different? Say, for instance, the Affordable Care Act never included a contraceptive mandate. And imagine the owners of Hobby Lobby, facing a tight labor market, realized the company was losing out on quality employees who were choosing employers with more comprehensive health plans that included all FDA-approved contraceptive devices. Could the owners of Hobby Lobby therefore reach out to other employers in the relevant labor market and ask them to agree to refuse contraceptive coverage in their benefit plans? The prospect of being able to downgrade their health plans without fear of competitive consequences might be appealing to employers. But such an agreement would also constitute an anticompetitive restraint on trade, which is prohibited by Section 1 of the Sherman Act.215 U.S.C. § 1.

While it may seem intuitive that corporate religious liberty rights do not (or should not) stretch so far as to justify anticompetitive activity, the conflict between the two has been largely overlooked.3But see Elizabeth Sepper & James D. Nelson, Government’s Religious Hospitals, 109 Va. L. Rev. 61, 110–17 (2023) (proposing antitrust as one possible solution to the prevalence of religiously restricted government hospitals).
It hovers at the margins of the exemptions debate, if one looks closely: In defending the right to religious exemptions, some of the most vigorous proponents of religious liberty have argued that religious exemptions should be permitted, as long as there are other market alternatives providing the same goods, services, or benefits.4See Elizabeth Sepper, Free Exercise Lochnerism, 115 Colum. L. Rev. 1453, 1477 (2015).
This is so, they argue, because, if the market provides sufficient alternatives, a religious exemption harms no one.5See Eugene Volokh, A Common-Law Model for Religious Exemptions, 46 UCLA L. Rev. 1465, 1520 (1999); see also Sepper, supra note 4, at 1478.
According to this line of argument, if a gay couple who is denied a wedding cake at one bakery can purchase a cake at the bakery down the street, or if a woman who is denied emergency contraception at her home pharmacy can purchase the medicine online, no substantial harm has occurred. Put differently, religious liberty advocates have successfully argued that the government’s only compelling interest is ensuring access to goods and services in the market and that, as a result, the existence of “a strong competitive market negate[s] any compelling state interest” in forcing religious business owners to provide goods, services, or benefits in violation of their sincerely held religious beliefs.6Richard A. Epstein, The Defeat of the Contraceptive Mandate in Hobby Lobby: Right Results, Wrong Reasons, 2014 Cato Sup. Ct. Rev. 35, 66; see also Brief of Douglas Laycock et al. as Amici Curiae in Support of Petitioners at 5, Obergefell v. Hodges, 576 U.S. 644 (2015) (No. 14-556), 2015 WL 1048450, at *5.
Refusing to provide a religious exemption is therefore permissible only if “markets will not solve the problem.”7See Andrew Koppelman, You Can’t Hurry Love: Why Antidiscrimination Protections for Gay People Should Have Religious Exemptions, 72 Brook. L. Rev. 125, 133 (2006); see also Sepper, supra note 4, at 1480–81.

As others have noted, this view “implies that a competitive market inflicts no harm that justifies government intervention in the private [market] order.”8See Sepper, supra note 4, at 1481.
But it also assumes that religious businesses are not acting in ways that impede market competition and, therefore, consumers’ ability to access alternative providers in the market. What if that assumption does not hold? What if religiously minded businesses act in ways that are specifically designed—like in the opening hypothetical—to limit access to certain goods and services not just with respect to their own businesses but others’ as well? Although religious-exemption advocates often accuse opponents of engaging in a parade of horribles,9See, e.g., Douglas Laycock, The Campaign Against Religious Liberty, in The Rise of Corporate Religious Liberty 231, 248 (Micah Schwartzman, Chad Flanders & Zoë Robinson eds., 2016).
religious market actors, specifically religious hospitals, have been engaging in such behavior for decades. Catholic hospitals, for instance, routinely require secular hospitals to cease providing a wide range of reproductive healthcare services (e.g., contraceptives, tubal ligations, and abortion) as a condition of membership in competitor collaborations.10See discussion infra Part I.
They have also imposed post-sale restrictions on the sale of Catholic hospitals, restrictions that prevent secular buyers from expanding the range of reproductive healthcare services provided, even in the face of strong community demand.11See discussion infra Part I.

The assumption that there are and will continue to be sufficient market alternatives to counteract religious hospitals’ refusal to serve is deeply troubling when those same hospitals require other, secular market actors to refuse care. When sufficient numbers of religious hospitals do so, it becomes increasingly likely, for example, that a woman who is denied a tubal ligation at her local Catholic hospital will find that, due to its contractual obligation, even the secular hospital down the street will not provide her with care.12See, e.g., Debra B. Stulberg et al., Tubal Ligation in Catholic Hospitals: A Qualitative Study of Ob–Gyns’ Experiences, 90 Contraception 422, 424 (2014), doi.org/10.1016/j.contraception.2014.04.015.
And the same is true for the woman seeking emergency contraception following a sexual assault,13In 2017, for example, fourteen hospitals in Pennsylvania informed the state’s Department of Health that they would not provide emergency contraception to sexual assault victims presenting for care. 47 Pa. Bull. 1598 (Mar. 11, 2017). At least one of those hospitals had been sold the year prior and lost its Catholic name and affiliation. Justin Heinze, East Norriton’s Mercy Suburban Hospital Acquired in New Deal, Patch (Feb. 1, 2016), https://patch.com/pennsylvania/norristown/east-norritons-mercy-suburban-hospital-acquired-new-deal-0 [perma.cc/RXJ9-KZNU].
the woman seeking to terminate a pregnancy due to a lethal fetal anomaly,14Lori R. Freedman & Debra B. Stulberg, Conflicts in Care for Obstetric Complications in Catholic Hospitals, AJOB Primary Rsch., Dec. 2013, at 1, 6.
and the woman experiencing a miscarriage but who is not yet hemorrhaging.15See, e.g., Lori Freedman, Willing and Unable: Doctors’ Constraints in Abortion Care 128 (2010).
In other words, such contractual arrangements make it increasingly likely that patients will be denied standard healthcare services even at institutions that possess no independent religious or moral objections to such services.16Elizabeth Sepper refers to these institutions as “zombie religious hospitals.” See generally Elizabeth Sepper, Zombie Religious Institutions, 112 Nw. U. L. Rev. 929 (2018).
And this is true in states spanning the spectrum of post-Dobbs legislation.

Advocates for reproductive healthcare access, of course, have been keenly aware of religious restrictions on care for decades now. But while advocates and scholars have considered antitrust law as a potential tool for preserving healthcare access following religious-secular hospital mergers,17See Judith C. Appelbaum, Nat’l Women’s Law Ctr., Hospital Mergers and the Threat to Women’s Reproductive Health Services: Using Antitrust Laws to Fight Back (1998); Judith C. Appelbaum & Jill C. Morrison, Hospital Mergers and the Threat to Women’s Reproductive Health Services: Applying the Antitrust Laws, 26 N.Y.U. Rev. L. & Soc. Change 1 (2000); Caitlin M. Durand, Note, Who Blesses This Merger? Antitrust’s Role in Maintaining Access to Reproductive Health Care in the Wake of Catholic Hospital Mergers, 61 B.C. L. Rev. 2595 (2020).
little attention has been paid to antitrust’s potential for combatting other types of religiously motivated restrictions.18But see Sepper & Nelson, supra note 3 (proposing antitrust as one possible solution to the prevalence of religiously restricted government hospitals, which sometimes come about through joint ventures or contractual arrangements).
This Article begins to fill this gap by considering whether Section 1 of the Sherman Act can be deployed to combat competitor collaborations and hospital sales that prohibit the provision of reproductive healthcare services at secular institutions. Catholic hospital stakeholders assert that these contractual arrangements are necessary to protect the Catholic healthcare mission, but, as this Article demonstrates, these arrangements are also anticompetitive. Religious restrictions on a religious-secular hospital collaboration ultimately limit output: The secular hospital must agree, in return for the Catholic hospital’s willingness to collaborate, to provide only those services the Catholic hospital would also be willing to provide. Similarly, post-sale religious restrictions on services boil down to an agreement not to compete; regardless of consumer demand and changing market conditions, the buyer may not enter into new service lines (or expand output in existing lines). Both agreement types lead to lower output and higher prices than would otherwise exist. And both, this Article argues, violate Section 1 of the Sherman Act.

Given the clear anticompetitive nature of these contractual arrangements and reproductive healthcare advocates’ desire to protect and promote access to care in a post-Dobbs world, it seems likely that antitrust litigation will target such arrangements sooner rather than later.19In 2024, the California Attorney General sued Providence St. Joseph Hospital for denying emergency abortion care to a miscarriage patient, alleging unfair competition under section 17200 of the Business and Professions Code. Complaint, California v. St. Joseph, No. CV2401832 (Cal. Super. Ct. Sep. 8, 2024).
In response, the defendant hospitals will likely argue that these agreements—what we might call “religious riders” to larger commercial agreements—are ancillary agreements that are reasonably necessary to achieve the procompetitive benefits of a larger procompetitive agreement. As this Article will show, however, such an argument fails for both doctrinal and practical reasons. Courts should hold the antitrust-doctrinal line and refrain from writing in a religious exemption to the Sherman Act.

Yet protection from liability might lie elsewhere. Changes in Supreme Court case law pose a nontrivial challenge for plaintiffs who file suit under the Sherman Act. Fifteen years ago, corporations could not have used religion to justify anticompetitive behavior.20This is because it was only in 2014 that the Supreme Court explicitly held that corporations possess religious liberty rights under the Religious Freedom Restoration Act. Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682 (2014). And the Court had long made clear that social justifications (which would necessarily include religious justifications) cannot justify anticompetitive behavior. NCAA v. Alston, 141 S. Ct. 2141, 2159 (2020) (“This Court has regularly refused . . . requests from litigants seeking special dispensation from the Sherman Act on the ground that their restraints of trade serve uniquely important social objectives beyond enhancing competition.”).
But since then, the Supreme Court has dramatically expanded religious-liberty rights, creating a potential opportunity for religious firms to do just that.21See, e.g., Groff v. DeJoy, 143 S. Ct. 2279 (2023) (holding that to defend denial of a religious accommodation under Title VII, employers must show that the burden of granting an accommodation would substantially increase costs); Mahmoud v. Taylor, 145 S. Ct. 2332 (2025) (requiring schools to provide religious opt-outs for LGBTQ+-inclusive storybooks).
This Article provides a first look at some of the key doctrinal issues that are likely to arise should a hospital raise a religious liberty defense to a Sherman Act violation. Whether or not the new religious liberty case law demands an exemption to the Sherman Act is a close one, but, ultimately, this Article argues that a religious liberty defense should fail.

This Article proceeds in four parts. Part I provides an overview of the increasingly religious nature of the American healthcare market, its implications for patients, and the ways in which religious restrictions have grown through “contract, not devotion.”22Sepper, supra note 16, at 933.
Part II substitutes a devotion lens for an antitrust lens and argues that scholars and observers have failed to fully interrogate the anticompetitive nature of religious healthcare institutions’ activities in our nation’s reproductive healthcare markets. Although religious-secular hospital mergers have gained considerable attention,23See discussion infra Part II.
less attention has been paid to other agreements between Catholic hospitals and secular hospitals—namely, agreements to limit output or not compete. These agreements should be deemed illegal under long-standing antitrust principles. Part III provides a preliminary look at some of the key doctrinal issues—under both the First Amendment and the Religious Freedom Restoration Act (RFRA)—that are likely to arise in a suit challenging religiously motivated restraints, like those considered in Part II. Part IV lays out a few practical details a litigant should consider when bringing these claims. First, although antitrust liability is joint and several, a plaintiff should sue only the secular hospital, as it is the secular hospital’s behavior—not that of the Catholic hospital—that injunctive relief can effectively redress. After all, the goal of any lawsuit is not to require the Catholic hospital to begin providing services to which it morally objects: Antitrust law does not (and cannot) require this. Second, the most appropriate plaintiffs are individual states, not individual consumers. This is because estimating damages for deadweight loss, a key harm caused by the restraints considered in Part II, is particularly challenging.

I. An Increasingly Religious Healthcare Market

Doctors are thinking through a medical framework designed to present patients with safe choices informed by science, and the bishops appear to view the same clinical moment through a theological framework designed to override or remove those choices in favor of their beliefs about God’s will.      — Lori Freedman24 Lori Freedman, Bishops and Bodies 44–45 (2023).

American society has grown less religious over the past several decades.25The percentage of Americans reporting that religion is very important in their own lives dropped from 70 percent in 1965 to 45 percent in 2023. How Religious Are Americans?, Gallup (Mar. 29, 2024), https://news.gallup.com/poll/358364/religious-americans.aspx [perma.cc/LP6C-466K].
Somewhat counterintuitively, this same period has seen a steady and significant increase in healthcare institutions operating under a religious standard of care, one that prohibits providers from offering many of the most common and in-demand reproductive health services. Notably, the increase in religiously restricted healthcare appears to have taken place through inorganic growth (e.g., mergers, acquisitions, competitor collaborations, and sale restrictions), as opposed to increasing consumer demand for theologically infused healthcare. 26See Sepper, supra note 16, at 937.

A. The Growth of Religiously Restricted Healthcare & Its Consequences for Women’s Health

Although a wide range of religious healthcare institutions exist (e.g., Baptist, Jewish, Episcopal, Catholic), the growth in religious healthcare mentioned above is driven primarily by an increase in Catholic healthcare. The percentage of short-term acute care hospitals in the United States that are Catholic-owned or affiliated with a Catholic system has steadily increased. Indeed, over the fifteen-year period between 2001 and 2016, the number of acute care hospitals that are Catholic-owned or -‍affiliated grew by 22 percent, while the overall number of hospitals in the United States decreased.27 Lois Uttley & Christine Khaikin, MergerWatch, Growth of Catholic Hospitals and Health Systems: 2016 Update of the Miscarriage of Medicine Report 1 (2016).
In absolute terms, this means that the total number of Catholic short-term acute care hospitals grew from 449 in 2001 to 577 in 2020.28 Tess Solomon, Lois Uttley, Patty HasBrouck & Yoolim Jung, Cmty. Catalyst, Bigger and Bigger: The Growth of Catholic Health Systems 13 (2020); see Sepper, supra note 16, at 970.
As of 2022, one in seven hospital beds are in a Catholic facility or affiliate.29Frances Stead Sellers & Meena Venkataramanan, Spread of Catholic Hospitals Limits Reproductive Care Across the U.S., Wash. Post (Oct. 10, 2022), https://www.washingtonpost.com/health/2022/10/10/abortion-catholic-hospitals-birth-control [perma.cc/5RBN-P6LP].

This growth has been especially pronounced in certain areas of the country. In ten states, more than 30 percent of acute care hospital beds and more than 30 percent of births are in Catholic facilities.30 Solomon et al., supra note 28, at 4.
The numbers are even higher in states such as Iowa, South Dakota, Washington, and Wisconsin—where 40 percent or more of acute care beds are in hospitals operating under Catholic doctrine—and in Alaska, where 46 percent of all acute care beds are located in a single Catholic hospital that is more than twice the size of any other hospital in the state.31Id. at 5; see Sepper, supra note 16, at 934–35.
Additionally, recent reports have found that the number of Catholic-owned, sole-community hospitals has also been increasing.32A hospital is a sole community hospital if it is located thirty-five miles from other like hospitals or is located in a rural area and meets one of several conditions. 42 C.F.R. § 412.92(a) (2024).
In 2011, 30 Catholic hospitals were designated by Medicare as “sole community hospitals”;33Maryam Guiahi, Catholic Health Care and Women’s Health, 131 Obstetrics & Gynecology 534, 534 (2018), doi.org/10.1097/AOG.0000000000002477.
by 2020, that number had risen to 52.34 Solomon et al., supra note 28, at 4.
Moreover, a more recent study found that there are now 132 “religious hospital monopolies”—areas in which all available hospitals are religious institutions—with 121 (about 91 percent) identifying as Catholic.35Sam Doernberg, Barak Richman & Lauren Taylor, Religious Hospital Monopolies, 184 JAMA Internal Med. 1152, 1152 (2024), doi.org/10.1001/jamainternmed.2024.3955.

The growth in Catholic healthcare is troubling to many healthcare advocates, particularly reproductive healthcare advocates, because Catholic healthcare systems operate under a religious standard of care wherein the “free and informed health care decision of the person” is followed only if “it does not contradict Catholic principles.”36 U.S. Conf. of Cath. Bishops, Ethical and Religious Directives for Catholic Health Care Services 14 (6th ed. 2018). In contrast, hospitals run by other religious groups are less likely to impose care restrictions, and some actively protect reproductive access. See Susan Berke Fogel, MergerWatch Project, Fighting Religious Health Restrictions: Preventing the Continuation of Restrictions When Religious Hospitals Are Sold 2 (2004). St. Luke’s, an Episcopal system and Idaho’s largest health system, recently sued the state attorney general seeking to extend court protections that would allow emergency abortions despite the state’s near total abortion ban. Kyle Pfannenstiel, Idaho’s Largest Health System Sues AG, Seeking Emergency Abortion Protections, Idaho Capitol Sun (Jan. 15, 2025), https://idahocapitalsun.com/2025/01/15/idahos-largest-health-system-sues-ag-seeking-emergency-abortion-protections [perma.cc/9LVS-NY4J].
Those principles are laid out in the Ethical and Religious Directives for Catholic Healthcare (“the Directives”), which are promulgated by the United States Conference for Catholic Bishops (USCCB) and approved by the Vatican.37 U.S. Conf. of Cath. Bishops, supra note 36, at 2; see also 1983 Code c.8, § 2; 1983 Code c.455, § 3.
The Directives are divided into six sections, each beginning with a theological reflection and ending with a list instructing Catholic hospitals on how to provide theologically permissible healthcare.38See U.S. Conf. of Cath. Bishops, supra note 36.

Although the Directives apply to all hospital activities and service lines, the greatest discrepancy between secular hospitals’ and Catholic hospitals’ approaches to healthcare involves the provision of (mainly women’s) reproductive healthcare services. While the Directives permit providing natural family planning services (to married couples) and prenatal and delivery care, Catholic hospitals’ ability to provide most standard forms of reproductive healthcare—including abortion, sterilization (vasectomies, tubal ligations, and hysterectomies), birth control, emergency contraception (including in the event of sexual assault), and many common infertility techniques—is limited.39Id. at 15–19.
Physicians employed at Catholic hospitals are prohibited from providing most forms of reproductive healthcare except when certain narrow factual circumstances render such services morally acceptable under Catholic doctrine.40Note also that there is considerable variation in terms of how Catholic hospitals—and their employees—interpret the Directives. See, e.g., Steven S. Smugar, Bernadette J. Spina & Jon F. Merz, Informed Consent for Emergency Contraception: Variability in Hospital Care of Rape Victims, 90 Am. J. Pub. Health 1372, 1372 (2000), doi.org/10.2105/AJPH.90.9.1372; Freedman, supra note 24, at 159–61.
Consider, for example, abortion care. Under the Directives, a direct abortion⎯any medical intervention that directly and intentionally kills a fetus or ends a pregnancy before viability⎯is never permitted.41 U.S. Conf. of Cath. Bishops, supra note 36, at 18–19.
However, an abortion is allowed if its “purpose [is] the cure of a proportionately serious pathological condition of a pregnant woman” and “cannot be safely postponed until the unborn child is viable.”42Id. at 19.
In this case, the abortion is considered to be indirect, making it morally permissible.

This religious standard of care most often comes into play when pregnant patients experiencing a miscarriage present at a Catholic hospital.43It also comes into play with respect to ectopic pregnancies, as it often means that patients are denied the least invasive treatments available. Angel M. Foster, Amanda Dennis & Fiona Smith, Do Religious Restrictions Influence Ectopic Pregnancy Management? A National Qualitative Study, 21 Women’s Health Issues 104, 105 (2011), doi.org/10.1016/j.whi.2010.11.006.
The full range of treatment options for a miscarriage include expectant management (waiting to see if the body completes the miscarriage without intervention), medication (misoprostol or mifepristone) to speed up the miscarriage process, or surgical removal of the fetus.44ACOG Comm. on Prac. Bulls.—Gynecology, Am. Coll. of Obstetricians & Gynecologists, ACOG Practice Bulletin No 200: Early Pregnancy Loss, Obstetrics & Gynecology (Nov. 2018), doi.org/10.1097/aog.0000000000002899.
If fetal heart tones are still present, the latter two treatments would constitute an abortion.45Freedman & Stulberg, supra note 14, at 6.
In most hospitals, doctors make treatment decisions based on the patient’s wishes and medical status. When a woman is medically stable, some women prefer to wait and see whether they can pass the pregnancy naturally.46Id.
Others may choose to expedite the process with the assistance of medication or surgery, particularly if the waiting is prolonged, pain is intense, or risk of complications is high.47Id. at 5–6.
When a woman is not medically stable or the chances that she will develop an infection are high, doctors often advise medical or surgical treatment over expectant management.48Id. at 6–7.

Hospitals operating under the Directives, however, can provide only expectant management when fetal heart tones are detected unless a medical or surgical abortion is necessary to save the woman’s life.49Id. at 6 (offering historical detail about the origin of Directive 47, which was created to allow for life-saving abortions within Catholic hospitals as the field of obstetrics and standards for hospital accreditation modernized); Lori R. Freedman, Uta Landy & Jody Steinauer, When There’s a Heartbeat: Miscarriage Management in Catholic-Owned Hospitals, 98 Am. J. Pub. Health 1774, 1776 (2008), doi.org/10.2105/AJPH.2007.126730 (reporting how approval for termination of pregnancy at one Catholic hospital would be denied unless “it looks like she’s going to die if we don’t do it”); Freedman, supra note 24, at 43, 114, 140.
Treating physicians who believe that medication or surgical abortion care is the appropriate treatment for a miscarrying pregnant patient must, before administering such treatment, demonstrate to the hospital’s Ethics Committee that the woman’s health or life is at serious risk. That is, the physician must wait until the pregnant patient’s condition becomes so critical that she is likely to die if denied abortion care. Under these conditions, the abortion procedure is permitted because it is intended specifically to cure the woman of serious illness, not to end the fetus’s life.50This scenario is familiar to those tracking how state abortion bans hinder emergency care, as such bans effectively impose the same religious standards long used by Catholic hospitals. See Mary Ziegler, Why Exceptions for the Life of the Mother Have Disappeared, Atl. (July 25, 2022), https://www.theatlantic.com/ideas/archive/2022/07/abortion-ban-life-of-the-mother-exception/670582 [perma.cc/6MNW-KCVU] (demonstrating the synergy between the Catholic intention-based definition of abortion and anti-abortion rhetoric post-Dobbs); see also Lori Freedman, Debra Stulberg & Elizabeth Reiner Platt, Not Here or There: How Catholic Hospital Abortion Bans Interact with State Bans, 28 J. Health Care L. & Pol’y 180, 197 (2025) (“State abortion bans drew heavily on the anti-abortion language and reasoning used in Catholic doctrine and the Directives, remaking state policies for all hospitals in their image.”).
Under these facts, the abortion is considered indirect and is, therefore, morally permissible. This is in sharp contrast to the secular care provided at non-Catholic hospitals,51That is, those operating in states without abortion bans.
where treatment is provided to prevent medical harm (e.g., hemorrhaging, infection, loss of fertility) a priori. As one physician working in both Catholic and non-Catholic hospitals explained:

Say somebody ruptured their membranes, or say somebody had a lethal anomaly, or somebody had no fluid and the prognosis was zero, in the non-Catholic hospital you would just consent them to put in some medicine to put them through labor, or do a D&E. And in the Catholic hospital you had to wait till they get sick . . . .52Freedman & Stulberg, supra note 14, at 6.

Notably, because of the Directives’ restrictions on abortion, it is common for physicians at Catholic hospitals to transfer miscarriage patients to secular competitors to receive care.53Because of this, some scholars argue that “care was only as safe in Catholic hospitals [pre-Dobbs] as it was because” Catholic hospitals could rely on secular facilities to act as an important safety valve. Freedman, Stulberg & Platt, supra note 50, at 182.
As one physician working at a Catholic hospital explained:

We often tell patients that we can’t do anything in the hospital but watch you get infected, and we often ask them if they would like to be transferred to a hospital that would go ahead and get them delivered before they get infected[.] . . . [W]e actually have the patients discharge themselves . . . drive themselves and then admit themselves to the next institution.54Freedman & Stulberg, supra note 14, at 7.

Such transfers, however, are not always possible.55This is particularly true in states that have instituted abortion bans following the fall of Roe v. Wade, 410 U.S. 113 (1973), overruled by, Dobbs v. Jackson Women’s Health Org., 142 S. Ct. 2228 (2022). See Freedman, Stulberg & Platt, supra note 50 (discussing how state-level abortion bans have eliminated secular hospitals’ ability to act as important safety valves for Catholic care).
As noted above, an increasing number of communities rely on just one Catholic hospital for all services. 56In 2016, for instance, three regions in Iowa were served soley by Catholic community hospitals: Carroll, Clinton, and Mason City. Uttley & Khaikin, supra note 27, at 6.
In such communities, pregnant patients denied care at the Catholic hospital may have no other recourse but to wait until their condition deteriorates sufficiently so as to justify abortion care under the Directives. Moreover, even when secular alternatives exist, the delay in receiving care can result in significant patient harm.57Delay can occur both because the nearest secular hospital is a considerable distance away and because the patient is not informed of the fact that her treatment options would be greater at a secular institution.
Dr. David Eisenberg, for example, explained that “the sickest patient” he ever cared for during his residency was a young pregnant woman whose water had broken far before fetal viability.58 Julia Kaye, Brigitte Amiri, Louise Melling & Jennifer Dalven, ACLU, Health Care Denied: Patients and Physicians Speak Out About Catholic Hospitals and the Threat to Women’s Health and Lives 12 (2016).
The Catholic Chicago-area hospital at which she presented refused to take steps to hasten delivery, and, by the time she was transferred to Dr. Eisenberg’s hospital ten days later, she had a fever of 106 degrees and was dying of sepsis. She survived, but she suffered an acute kidney injury requiring dialysis and a cognitive injury due to the severity of her sepsis.59Id.
“To this day,” Dr. Eisenberg recalled, he has “never seen someone so sick—because we would never wait that long before evacuating the uterus.”60Id.
More recently, the California Attorney General filed a complaint against a Catholic hospital after the hospital refused to provide abortion care to a woman experiencing a miscarriage at fifteen-weeks, instead discharging her—with the offer of a bucket and towels—so she could drive to a nearby community hospital. By the time she arrived at the secular provider, she was actively hemorrhaging.61Molly Castle Work, Catholic Hospital Offered Bucket, Towels to Woman It Denied an Abortion, California AG Said, Nat’l Cath. Rep. (Oct. 10, 2024), https://www.ncronline.org/news/catholic-hospital-offered-bucket-towels-woman-it-denied-abortion-california-ag-said [perma.cc/GM68-AHN3].

B. Growth Through Contract, Not Devotion

The growth in religiously restricted healthcare is likely puzzling to those who have been tracking the steady decline in religiosity among Americans over the past several decades,62In 1973, 87 percent of U.S. adults identified with a Christian religion. In 2023, that number had dropped down to 68 percent, while the number of people with nonreligious preferences rose from 5 percent to 22 percent. Gallup, supra note 25.
not to mention the strong (and growing) support for reproductive rights, even among most Catholic Americans.63Today, 63 percent of Americans say abortion should be legal in all or most cases. Public Opinion on Abortion, Pew Rsch. Ctr. (June 12, 2025), https://www.pewresearch.org/religion/fact-sheet/public-opinion-on-abortion [perma.cc/7YYZ-S2A2]. Even more—92 percent—say that using contraception is morally acceptable. Megan Brenan, Americans Say Birth Control, Divorce Most ‘Morally Acceptable’, Gallup (June 9, 2022), https://news.gallup.com/poll/393515/americans-say-birth-control-divorce-morally-acceptable.aspx [perma.cc/QB8S-GQKS].
But the reason is simple: As Elizabeth Sepper has documented, the available evidence suggests that much of the growth—and maintenance—of religiously restricted healthcare has been driven by contract, not conversion.64See Sepper, supra note 16, at 933.
The growing number of healthcare institutions operating under a religious standard of care is explained by Catholic hospitals’ and systems’ aggressive approach to mergers, acquisitions, and competitor collaborations65Id. at 937–40.
—not through the construction of new hospitals in response to community demand. At the same time, Catholic hospitals and systems have sought to prevent new secular options by imposing religious restrictions on the sale of Catholic hospitals to secular buyers.66Id. at 940–42.

Of course, turning to acquisitions and collaborative arrangements to remain competitive is not unique to Catholic hospitals. The 1980s and 1990s saw a rise in merger and affiliation agreements by both secular and religious hospitals as a result of changing market dynamics,67Mergers and affiliations can improve healthcare institutions’ ability to borrow money to upgrade facilities, to save money through joint purchasing and shared administrative and billing services, and not the least, to allow for a greater market share and thus a stronger position when negotiating with insurers. Tamar Lewin, With Rise in Health Unit Mergers, Catholic Standards Face Challenge, N.Y. Times (Mar. 8, 1995), https://www.nytimes.com/1995/03/08/us/with-rise-in-health-unit-mergers-catholic-standards-face-challenge.html [perma.cc/WHL4-8RRE]; see also Appelbaum, supra note 18, at 1 (“Driven by pressures to cut costs and consolidate resources, hospitals are increasingly turning to mergers and other forms of affiliation with one another, producing what commentators have dubbed a ‘merger mania.’ ”); Sepper, supra note 16, at 937–38.
including shifts in care modalities and reimbursements in the market that necessitated consolidation.68Sandra DiVarco, Kerrin Slattery, & William Grogan, Compliance Concerns for Catholic Health Care Collaborations, Law360 (Sep. 5, 2018), https://www.law360.com/articles/1079031/compliance-concerns-for-catholic-health-care-collaborations [perma.cc/F9JR-L7HU].
This consolidation trend has continued in more recent decades, with 1,573 mergers taking place from 1998 to 2017 and another 428 hospital and health system mergers announced from 2018 to 2023.69Zachary Levinson, Jamie Godwin, Scott Hulver & Tricia Neuman, Ten Things to Know About Consolidation in Health Care Provider Markets, KFF (Apr. 19, 2024), https://www.kff.org/health-costs/issue-brief/ten-things-to-know-about-consolidation-in-health-care-provider-markets [perma.cc/7T5L-XVZC].

But Catholic hospitals are unique in that the Directives govern not only their healthcare services but also their approach to acquisitions, partnerships, and other types of competitor collaborations. This has been true since 1994, when the USCCB added a sixth section to the Directives titled “Forming New Partnerships with Health Care Organizations and Providers.”70See U.S. Conf. of Cath. Bishops, Ethical and Religious Directives for Catholic Health Care Services 34 (5th ed. 2009); Introducing the Revised Directives, Cath. Health Ass’n of the U.S.: Health Progress (Apr. 1995), https://www.chausa.org/news-and-publications/publications/health-progress/archives/april-1995/introducing-the-revised-directives [perma.cc/W6XR-XWH4] (calling the 1994 version “a total revision of the [Directives]” and noting inclusion of the new sixth section).
This revision was driven by the recognition that, while historically “most health care providers enjoyed a degree of independence from one another,” Catholic healthcare providers were increasingly merging with or affiliating with other healthcare providers.71 U.S. Conf. of Cath. Bishops, supra note 70, at 34, 26. Between 1990 and 2001, there were 171 mergers between Catholic and secular systems. Fogel, supra note 36, at 2.
And although “new partnerships [could] be viewed as opportunities for Catholic health care institutions and services to witness to their religious and ethical commitments and so influence the healing profession,” they also pose “the danger of scandal in any association with abortion providers.”72 U.S. Conf. of Cath. Bishops, supra note 70, at 34–35. “Scandal is an attitude or behavior which leads another to do evil . . . .” Id. at 42 n.45 (quoting U.S. Conf. of Cath. Bishops, Catechism of the Catholic Church 551 (2d ed. 2000)).
By partnering with secular healthcare providers who provided “immoral” care, Catholic hospitals might lead consumers to believe that receiving (purchasing) such healthcare is, in fact, permissible. Accordingly, the Directives instruct Catholic hospitals to first seek out Catholic health partners over secular health partners when engaging in healthcare collaborations or partnerships.73Id. at 35.

Recognizing that this might not always be possible, however, the Directives also provide instructions for how Catholic hospitals can collaborate with non-Catholic hospitals in a theologically permissible way. Directive 70 prohibits Catholic healthcare organizations from engaging in “immediate material cooperation in actions that are intrinsically immoral, such as abortion, euthanasia, assisted suicide, and direct sterilization.”74 U.S. Conf. of Cath. Bishops, supra note 36, at 25.
Directive 73 requires Catholic hospitals to ensure that “neither its administrators nor its employees will manage, carry out, assist in carrying out, make its facilities available for, make referrals for, or benefit from the revenue generated by immoral procedures.”75Id. at 26.
Moreover, as stated in Directive 74, “[i]n any kind of collaboration, whatever comes under control of the Catholic institution—whether by acquisition, governance, or management—must be operated in full accord with the moral teaching of the Catholic Church, including these Directives.”76Id.

To comply with their acquisition or collaboration agreement, many formerly secular hospitals and providers have agreed to limit the range of reproductive healthcare services they originally provided.77Sepper, supra note 16 at 937–40.
Abortion services are the most common services to be cut,78Assuming they are offered. Elective abortion care has largely been pushed out of hospitals and into specialized clinics over the past several decades. See generally Sonya Borrero, Mehret Birru Talabi & Christine Dehlendorf, Confronting the Medical Community’s Complicity in Marginalizing Abortion Care, 328 JAMA 1701 (2022), doi.org/10.1001/jama.2022.18328.
but sterilizations, contraception, and in vitro fertilization services have all been on the chopping block.79See Sepper, supra note 16, at 938, 971.
For instance:

  • When a new health center was formed by the merger of Lorain Community Hospital and St. Joseph Hospital and Health Center in 1995—the only two hospitals in Lorain, Ohio—the resulting center ceased providing tubal ligations and vasectomies “to make accommodations to the church’s ethical directives.”80ACLU May Sue Over Dropped Services, Mod.

  • When four nonsectarian hospitals entered into a consortium with two Catholic hospitals in St. Petersburg, Florida, in 1997, the nonsectarian hospitals agreed to cease providing abortion, in vitro fertilization, and sterilization services.81Wes Allison & Bryan Gilmer, Bayfront to Leave BayCare, Tampa Bay Times (Sep. 28, 2005), https://www.tampabay.com/archive/2000/10/24/bayfront-to-leave-baycare [perma.cc/4LX7-BKNK].
  • When Nathan Littauer Hospital of Gloversville, New York, and St. Mary’s Hospital of Amsterdam, New York, formed an affiliation called TriCounty Health in the early 2000s, Nathan Littauer agreed to discontinue abortion, sterilization, and contraceptive counseling services.82 Caths. for a Free Choice, Merger Trends 2001: Reproductive Health Care in Catholic Settings 24 (2002).
  • When historically secular Sierra Vista Regional Health Center entered a two-year trial affiliation with the Catholic Carondelet Health Network in 2010, Sierra Vista—the sole community provider of acute care in a rural three-county region of Arizona—began fully adhering to the Directives.83 Lois Uttley & Sheila Reynertson, MergerWatch, & Lorraine Kenny & Louise Melling, ACLU, Miscarriage of Medicine: The Growth of Catholic Hospitals and the Threat to Reproductive Health Care 14 (2013) [hereinafter MergerWatch 2013].

  • When Hoag Presbyterian Hospital in Newport Beach, California, entered a partnership with St. Joseph Health in 2013, it announced it would cease providing elective abortions.85Billy Gil, Major O.C. Hospital Allowed to Continue Abortion Ban, LAist (Apr. 4, 2014), https://laist.com/news/major-oc-hospital-allowed-to-contin [perma.cc/DVJ3-JLRJ].

Catholic hospitals and systems have also taken affirmative steps to ensure that their exit from any particular market will not lead to an increase in religiously prohibited services.86Sepper, supra note 16 at 940–46.
Although the Directives do not speak to the sale of Catholic hospitals, Catholic hospitals and healthcare systems have often demanded that interested secular buyers contractually commit to adhering to the Directives, often in perpetuity.87See, e.g., Fogel, supra note 36, at 10.

For example, when Tenet Healthcare purchased a Catholic hospital (Queen of Angels/Hollywood Presbyterian Medical Center) in Los Angeles in 1998, it agreed to continue enforcing the Directives from 1998 to 2018 and ensure that any subsequent owners did as well.88Id. at 4.
Similarly, when the private-equity firm Cerberus Capital Management purchased the six-hospital Caritas Christi Health Care System in Boston in 2010, it agreed to maintain compliance with the Directives while simultaneously transforming the six hospitals into for-profit entities.89Caritas Christi Health Care System to be Acquired by Cerberus Capital Management, L.P., Cerberus (Mar. 25, 2010), https://www.cerberus.com/media-center/caritas-christi-health-care-system-to-be-acquired-by-cerberus-capital-management-l-p [perma.cc/3FRU-ZCFE]; see also Ron Shinkman, Cerberus Acquires Caritas Christi Health Care, Fierce Healthcare (Aug. 30, 2011), https://www.fiercehealthcare.com/finance/cerberus-acquires-caritas-christi-health-care [perma.cc/H5AB-AA4Y].
Moreover, Steward (the for-profit formed by Cerberus) signed a “stewardship agreement” with the Roman Catholic Archbishop of Boston affirming that “all Hospitals will be operated in accordance with the moral, ethical and social teachings of the Roman Catholic Church as expressed in the Directives and as interpreted solely and exclusively by” the archbishop.90Stewardship Agreement Between Steward and Roman Catholic Archbishop of Boston Regarding Caritas Christi 1, 3 (Apr. 30, 2010), http://www.mass.gov/ago/docs/nonprofit/caritas/executed-stewardship-agreement.pdf [perma.cc/8DJL-E4L2].
This agreement included a $25 million “termination contribution” clause that applied if the archbishop determined that the for-profit owners had not lived up to their religion-based obligations.91Id. at 8, 12, 15.
The agreement also provided that if the six hospitals were sold or merged with other institutions, Steward would pay the archbishop up to $25 million unless it could secure a purchaser’s commitment to the Directives.92See id. at 13–14; Sepper, supra note 16, at 943–44.

Catholic hospitals provide healthcare services in accordance with religious doctrine as interpreted by the United States Conference of Catholic Bishops. Yet Catholic hospitals are not the only ones that are operating under Catholic doctrine. Due to Catholic hospitals’ imposition of—and secular hospitals’ and buyers’ acquiescence to—contractual terms imposing religious restrictions on care, many secular institutions are also operating under Catholic doctrine.

II. Applying an Antitrust Lens

Catholic hospitals have the right to refuse to provide services they believe are immoral.93“Conscience refusal laws,” which exist at both the federal- and state-level, exempt healthcare providers from duties of patient care that are imposed by federal and state law governing medical institutions and professionals. See generally Elizabeth Sepper, Conscientious Refusals of Care, in The Oxford Handbook of U.S. Health Law 354 (I. Glenn Cohen, Allison K. Hoffman & William M. Sage eds., 2015).
But Catholic hospitals’ imposition of Catholic doctrine on secular hospitals as a matter of contract is concerning because it means that consumers might be denied standard healthcare services even at institutions that possess no independent religious or moral objections to those services. Indeed, consumers’ ability to access the full spectrum of reproductive healthcare services is increasingly dependent upon the market share of religiously restricted healthcare in their community.

Faced with this reality, healthcare advocates have searched for ways to maintain access to care.94E.g., Appelbaum, supra note 17; Bailey Sanders, Barak Richman, Kierra B. Jones, Andrea Ducas & Samuel Doernberg, Growing Market Power Among Catholic Hospitals Restrains Access to Reproductive Health Care, Ctr. for Am. Progress (Sep. 29, 2025), https://www.americanprogress.org/article/growing-market-power-among-catholic-hospitals-restrains-access-to-reproductive-health-care [perma.cc/4DRT-NGTP].
Antitrust laws provide a promising avenue to maintain such access. Antitrust law, writ large, aims to ensure fair and rigorous competition in the marketplace, thereby promoting both consumer welfare and economic efficiency.95See generally Christine S. Wilson, Comm’r, FTC, Luncheon Keynote Address at George Mason Law Review 22nd Annual Antitrust Symposium: Antitrust at the Crossroads? (Feb. 15, 2019), https://www.ftc.gov/system/files/documents/public_statements/1455663/welfare_standard_speech_-_cmr-wilson.pdf [perma.cc/L7WB-GY89].
In pursuit of these goals, antitrust law is designed to prevent harmful monopolies and other anticompetitive practices that harm consumers and businesses. Specifically, the Sherman Act prohibits anticompetitive restraints on trade, monopolization, and the attempt to monopolize.9615 U.S.C. §§ 1, 2.
The Clayton Act, in turn, prohibits mergers or acquisitions that are substantially likely to lessen competition.97Id. § 18.
And the Federal Trade Commission Act (FTC Act), among other things, prohibits unfair competition methods.98Id. § 45.

Yet, while litigants can use all three antitrust statutes to protect market competition for reproductive healthcare services, legal activism over the past several decades has focused on hospital mergers—and, therefore, Section 7 of the Clayton Act.99See generally, Appelbaum, supra note 17; Appelbaum & Morrison, supra note 17; Durand, supra note 17; Sepper & Nelson, supra note 3, at 111 (suggesting that rigorous review of hospital transactions might be beneficial). Elizabeth Sepper and James D. Nelson propose using the antitrust laws to counter government efforts to enter into joint ventures or other contractual arrangements with religious hospitals. Sepper & Nelson, supra note 3, at 112. However, because the state action doctrine in antitrust law permits state governments to displace competition, it seems likely that states can therefore choose to displace competition by allowing religious restrictions in government-owned hospitals. See infra note 202. I focus my analysis solely on agreements taking place between private market actors.
Less attention has been paid to how other antitrust laws might promote and preserve access to reproductive healthcare. This Article begins to fill this gap by considering whether Section 1 of the Sherman Act can be deployed to combat competitor collaborations and hospital sales that prevent the provision of reproductive healthcare services at secular institutions.100I consider whether Section 5 of the FTC Act and similar state laws can be used to promote access to reproductive healthcare in a separate project. See Bailey K. Sanders, Hidden Conscience Refusals: A Market Perspective (Oct. 12, 2025) (unpublished manuscript) (on file with the Michigan Law Review); see also Sanders et al., supra note 94.

A. Section 1 Violations?

Section 1 of the Sherman Act prohibits “[e]very contract, combination . . . or conspiracy, in restraint of trade or commerce.”10115 U.S.C. § 1.
That is, it is focused on agreements (collusive behavior) between market actors, not unilateral behavior. Further, although a literal reading of the statute would arguably make every restraint on trade illegal,102Nat’l Soc’y of Pro. Eng’rs v. United States, 435 U.S. 679, 687–88 (1978) (“The statute says that ‘every’ contract that restrains trade is unlawful. But, as Mr. Justice Brandeis perceptively noted, restraint is the very essence of every contract; read literally, § 1 would outlaw the entire body of private contract law.”).
the Supreme Court has long held that the Sherman Act prohibits only unreasonable—that is, anticompetitive—restraints of trade.103State Oil Co. v. Khan, 522 U.S. 3, 10 (1997).
This is because many agreements (restraints) in the marketplace are actually procompetitive in nature and, therefore, desirable.

Of course, there are also many anticompetitive agreements, and courts must determine whether a particular challenged restraint violates the Sherman Act. In doing so, courts generally distinguish between agreements that are per se illegal and those that may or may not be illegal, depending on the facts. Thus, a small set of restraints will be found to be “unreasonable per se because they ‘always or almost always tend to restrict competition and decrease output.’ 104Ohio v. Am. Express Co., 138 S. Ct. 2274, 2283 (2018) (emphasis omitted) (quoting Bus. Elecs. Corp. v. Sharp Elecs. Corp., 485 U.S. 717, 723 (1988)).
These type of restraints are so inherently anticompetitive and damaging to market competition that the courts have concluded there is no need to further inquire into their market effects. 105NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 100 (1984).
Classic examples of such per se restraints are agreements to rig bids, set or limit output, fix prices, and allocate markets.106“Horizontal price fixing and output limitation are ordinarily condemned as a matter of law under an ‘illegal per se’ approach because the probability that these practices are anticompetitive is so high . . . .” Id.; see also United States v. Topco Assocs., 405 U.S. 596, 608–09 (1972); United States v. Am. Linseed Oil Co., 262 U.S. 371, 388–90 (1923); Am. Column & Lumber Co. v. United States, 257 U.S. 377, 410–12 (1921).
For most challenged restraints, however, courts will apply the “rule of reason.”107Courts also sometimes apply what is called the abbreviated, or “quick look,” rule of reason analysis. This is “ ‘an intermediate standard’ and ‘applies in cases where per se condemnation is inappropriate but where no elaborate industry analysis is required to demonstrate the anticompetitive character of an inherently suspect restraint.’ ” Deutscher Tennis Bund v. ATP Tour, Inc., 610 F.3d 820, 830 (3d Cir. 2010) (quoting United States v. Brown Univ., 5 F.3d 658, 669 (3d Cir. 1993)).
The rule of reason requires courts to conduct a more intensive, fact-specific assessment of the market to assess whether the restraint’s anticompetitive effects outweigh its procompetitive effects. 108Am. Express, 138 S. Ct. at 2284.
If the restraint’s procompetitive effects outweigh the anticompetitive effects, the restraint is not illegal.

Importantly, noneconomic justifications for anticompetitive behavior are never cognizable as a defense against antitrust liability. Although defendants have frequently tried to justify anticompetitive behavior as necessary to achieve some particularly important social good, the Supreme Court has continually rebuffed those efforts. 109NCAA v. Alston, 141 S. Ct. 2141, 2159 (2021) (“This Court has regularly refused . . . requests from litigants seeking special dispensation from the Sherman Act on the ground that their restraints of trade serve uniquely important social objectives beyond enhancing competition.”).
And this is true even in the so-called “learned professions” of law, medicine, engineering, and the like.110See, e.g., Goldfarb v. Va. State Bar, 421 U.S. 773, 787 (1975) (“The nature of an occupation, standing alone, does not provide sanctuary from the [antitrust laws.]”).
For instance, in National Society of Professional Engineers v. United States,111Nat’l Soc’y of Pro. Eng’rs v. United States, 435 U.S. 679, 693–94 (1978).
the Court rejected the defendants’ argument that the challenged restraint was necessary to protect the public from shoddy engineering work; to accept such an argument, the Court explained, would be to accept that competition—the very good sought by the antitrust laws—was harmful.112Id. at 695 (stating that petitioner’s justification “is nothing less than a frontal assault on the basic policy of the Sherman Act”).
Similarly, in FTC v. Superior Court Trial Lawyers Ass’n, the Supreme Court refused to consider the “social utility or political wisdom” of a boycott among state-appointed criminal defense lawyers.113FTC v. Superior Ct. Trial Laws. Ass’n, 493 U.S. 411, 421–22 (1990).
Thus, the courts have firmly rejected the argument that certain restraints should be entitled to an antitrust exemption simply because competitors may have motivations (e.g., protecting the public or defending the indigent) other than profit.114In Goldfarb, for example, the Court explained that the “the public-service aspect of professional practice” is not “controlling in determining whether [antitrust law] includes professions.” Goldfarb, 421 U.S. at 787. The Supreme Court has made very clear that the fact that a party is organized as a nonprofit entity is irrelevant. NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 100 n.22 (1984) (“There is no doubt that the sweeping language of § 1 applies to nonprofit entities . . . .”).

In the next two Sections, I apply these fundamental antitrust principles to Catholic hospitals’ imposition of (and secular hospitals’ acquiescence to) religiously motivated output restrictions in the context of competitor collaborations and hospital sales. The analysis shows that these restraints “involve[] the same conduct, and cause[] the same harm[s], as traditional antitrust wrongdoing.”115Daniel Francis, Post-Profit Antitrust, 135 Yale L.J. 194, 194 (2025).
And although hospitals may claim these anticompetitive restraints are reasonably necessary to achieve certain procompetitive effects, there are doctrinal and practical reasons to reject such a claim.

1. Agreements to Reduce Output in Reproductive Service Lines

First, consider religious-secular competitor collaborations wherein a secular hospital agrees to cease providing (or provide fewer) reproductive healthcare services as a condition of the collaboration.116Except as otherwise indicated by context, “competitor collaboration” and “competitor partnerships” are used interchangeably with the term “joint venture.” The focus is on horizontal competitor collaborations where the parties integrate to some degree but continue to operate independently.
Healthcare collaborations, which can range from loose affiliations to more integrated joint ventures, can be permissible under antitrust law when their net effect is procompetitive; collaborating, for example, might allow two institutions to achieve cost savings and quality improvements that would be difficult to achieve individually.117See, e.g., Advisory Opinion to Miles, FTC (Feb. 19, 2002), https://www.ftc.gov/legal-library/browse/advisory-opinions/advisory-opinion-miles-02-19-02 [perma.cc/8HSJ-HD4K].
But healthcare collaborations, because they involve agreements among competitors, also raise the possibility of a Sherman Act Section 1 violation. If a collaboration involves an agreement that, standing alone, might be per se illegal, one must consider whether the agreement is a “naked” restraint on trade118Aya Healthcare Servs. v. AMN Healthcare, Inc., 9 F.4th 1102, 1109 (9th Cir. 2021).
or an “ancillary” agreement—an agreement that is subordinate and collateral to a legitimate transaction and reasonably necessary to achieve the procompetitive goals of the venture. If it is the latter, it must be subject to the rule of reason.119Id.

For example, two hospitals might form a joint venture to purchase a new robotic surgery system that physicians from both hospitals will use. Agreements regarding the purchase and operation of such a system would likely be viewed as ancillary to the joint venture—they are related and reasonably necessary to achieve its goals.120See Urological Stone Surgeons, Inc., 125 F.T.C. 513, 516, 525–26 (1998), 1998 WL 34077361.
But an agreement between the hospitals to set service prices that are not furnished through the joint venture, in contrast, is likely to be viewed as a naked restraint on trade and therefore per se illegal.121See Urological Stone Surgeons, 125 F.T.C. at 525–26.

With this in mind, let us consider the competitive implications of a religious-secular competitor collaboration that involves religious restrictions on care. This stylized hypothetical will guide the discussion:

Hospital A and Hospital B are independent competitors in County C. Both possess obstetrics and gynecology departments that provide reproductive healthcare services from prenatal care through delivery. They decide to enter a joint venture whereby they will combine resources to deliver higher quality care and lower costs across service lines. However, because Hospital A adheres to the Directives, the parties agree that Hospital B will cease providing elective abortions, elective contraceptives, elective sterilization procedures, in vitro fertilization, and certain forms of miscarriage care, except as permitted under the Directives.

The competitive effects of what one might call the “religious rider,” the requirement that Hospital B start adhering to the Directives, can be easily parsed out. Hospital B has agreed to exit one reproductive service line (in vitro fertilization, which is never permitted under the Directives) and to artificially limit output in others (abortion care, contraceptive care, and sterilizations).122We might say that this joint venture is engaging in “product exclusion.” “Product exclusion occurs when a venture disapproves a particular product, or decides not to permit the product to be produced within the venture.” Herbert Hovenkamp, Exclusive Joint Ventures and Antitrust Policy, 1995 Colum. Bus. L. Rev. 1, 65.
This means that the market for in vitro fertilization has lost a competitor (and all of its output) while the other markets will see a significant decrease in output as Hospital B begins providing services in only limited, theologically permissible circumstances. 123If an agreement “is formed with the objectively intended purpose or likely effect of increasing price or decreasing market wide output in the short run,” it may be considered a naked restraint on competition. 11 Phillip E. Areeda & Herbert Hovenkamp, Antitrust Law: An Analysis of Antitrust Principles and Their Application ¶ 1906a, at 235 (5th ed. 2024).
For example, while Hospital B would have previously provided a patient with a tubal ligation for sterilization purposes, it will now provide patients with a tubal ligation only if they can demonstrate a medical need. In either case, the decrease in output means that Hospital B will turn away some (indeed many) consumers seeking reproductive healthcare.

Several consequences flow from this output reduction. First, some consumers will go without care, perhaps because their need was time-sensitive or because financial challenges bar them from going elsewhere.124See Stulberg et al., supra note 12, at 423.
This denial of care constitutes deadweight loss, a form of inefficiency associated with reduced output.125See generally Christopher R. Leslie, Antitrust Damages and Deadweight Loss, 51 Antitrust Bull. 521, 522 (2006).
Second, some number of consumers will seek care at an alternative provider in the market. The alternative providers, in turn, will experience an increase in market share (i.e., market power) that will provide them with the ability to charge higher prices.126“This is because (everything else equal) the greater the market share of a firm, the greater is its ability (and thus temptation) to reduce its individual output and cause a price rise in the entire market.” Richard J. Hoskins, Antitrust Analysis of Joint Ventures and Competitor Collaborations: A Primer for the Corporate Lawyer, 10 U. Mia. Bus. L. Rev. 119, 121 (2002). The extent to which these additional providers can raise prices will depend on how many exist in the market.
Consumers who purchase care at these providers, then, will suffer an overcharge due to the supracompetitive price. This, of course, is no different from what happens when a cartel agrees to reduce output to raise the price of a product. In such a scenario, some socially beneficial transactions do not occur, while others take place at a supracompetitive price.127One wrinkle is that Hospitals A and B are not imposing this restraint, presumably, to raise their own prices (as cartel members do). But if prices in the larger market rise because of this agreement, it seems plausible that Hospitals A and B will respond by raising their prices as well. Moreover, as Daniel Francis has argued, “antitrust can and should” account for anticompetitive conduct that may result from non-profit-maximizing behavior. Francis, supra note 115, at 199.

But it is also important to think about how the agreement impacts competition between Hospital A and Hospital B specifically. External conditions can make it more or less costly for individuals or corporations to adhere to religious principles. As McConnell and Posner explain, “If contraceptives are illegal, a Catholic will experience little incremental cost from obeying the Church’s teaching against birth control, but once they are legalized the Catholic will face a temptation to stray from the Church’s teaching.”128Michael W. McConnell & Richard A. Posner, An Economic Approach to Issues of Religious Freedom, 56 U. Chi. L. Rev. 1, 57–58 (1989).
The same logic holds for religious businesses that seek to profit in a competitive market: The legalization of services prohibited by the Church puts Catholic hospitals at a competitive disadvantage because they cannot provide as many services as their competitors—or at least not without experiencing a theological cost.

For instance, both Hospital A and Hospital B compete to treat patients presenting at the emergency room experiencing a miscarriage. They also compete to treat patients who are seeking prenatal and delivery services. But Hospital B—prior to the agreement—provided a wider range of treatment options to these patients.129A woman who chose Hospital B for prenatal and delivery services could count on being able also to receive a tubal ligation or contraceptive counseling from her provider.
In doing so, it exerted pressure on Hospital A to also provide a greater range of services. 130Note that we cannot assume that a Catholic hospital or its managers will never deviate from the Directives or even share the same interpretation of the Directives. In the 1960s, more liberal Catholic dioceses began construing the Directives more leniently with respect to contraception. See Kevin D. O’Rourke, Thomas Kopfensteiner & Ron Hamel, A Brief History: A Summary of the Development of the Ethical and Religious Directives for Catholic Health Care Services, Health Progress, Nov.–Dec. 2001, at 18, 19. And experience shows that different bishops interpret the Directives differently. “[W]hat is acceptable to a bishop in one diocese may not be acceptable to the bishop in the next.” Patricia Donovan, Hospital Mergers and Reproductive Health Care, 28 Fam. Plan. Persps. 281, 283 (1996).
By agreeing not to provide more services than its religious counterpart, Hospital B is therefore reducing pressure on Hospital A to provide the full range of reproductive healthcare despite its religious objections to doing so.

Finally, while it can often be difficult to parse out anticompetitive effects on quality of care,131See Peter J. Hammer & William M. Sage, Antitrust, Health Care Quality, and the Courts, 102 Colum. L. Rev. 545, 548 (2002) (finding that surprisingly few antitrust cases deal with quality as a specific competitive dimension).
this is not the case when we are faced with a religious output restriction that reduces the treatment options providers can provide to patients. Here, the negative quality effects are built into the agreement. First, the elimination of particular services obviously negatively impacts the quality of care—patients are simply denied care! Second, as detailed in Part I, the religious standard of care practiced at Catholic hospitals is not always the standard of care: Physicians at Catholic hospitals report being forced to provide substandard care with respect to postpartum tubal ligations,132Stulberg et al., supra note 12, at 425.
ectopic pregnancy management,133See Foster, Dennis & Smith, supra note 43, at 106.
and timely miscarriage management.134Freedman, Landy & Steinauer, supra note 49, at 1776–77; Freedman & Stulberg, supra note 14, at 6.
Yet, because Hospital B has agreed to provide only care that Hospital A would itself be willing to provide, the community is now faced with two hospitals that provide substandard reproductive healthcare. Indeed, Hospital B can no longer serve as an important escape valve for patients who present at Hospital A only to be denied care.135Freedman, Stulberg & Platt, supra note 50, at 182.

Put simply, there are clear and serious anticompetitive effects flowing from the religious rider that accompanies the collaboration agreement. The relevant question is, then, whether this agreement constitutes a “naked” restraint on trade that is per se illegal or an “ancillary” agreement that is reasonably necessary to achieve the overall procompetitive goals of the larger collaboration. And here, for simplicity’s sake, we will assume that the overall collaboration does result in procompetitive effects (in other service lines). If this were not the case, the collaboration as a whole would be impermissible under the rule of reason.136Copperweld Corp. v. Indep. Tube Corp., 467 U.S. 752, 768 (1984).

Plaintiffs challenging this religious rider would, of course, argue that the rider constitutes a “naked” agreement on trade. If an agreement “is formed with the objectively intended purpose or likely effect of increasing price or decreasing market wide output in the short run,” it may be considered a naked restraint on competition.137 Areeda & Hovenkamp, supra note 123, ¶ 1906a, at 235; see also NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 100 (1984).
Here, of course, the explicit purpose of the religious rider is to decrease market output at Hospital B. And its only effect in the market for reproductive healthcare services is anticompetitive; it has no plausible redeeming procompetitive effects.

Moreover, from an economic standpoint, the rider bears no rational relation to increased efficiency or improved care in other service lines. Even if the overall collaboration allows the two hospitals to achieve such effects, there is no reason why the large partnership’s procompetitive benefits could be achieved if Hospital B provides only “medically indicated” contraception and sterilization to patients presenting at its facilities but could not be achieved if Hospital B provided contraception and sterilization to patients who wanted it for birth control purposes as well. Moreover, if the agreement “produced procompetitive efficiencies, [it] would increase output and reduce the price” of services, not reduce the available services while increasing the ability of other market competitors to raise prices.138Bd. of Regents, 468 U.S. at 114. In making their argument, plaintiffs would do well to highlight the similarities between the output restriction and the one considered in NCAA v. Board of Regents. There the Court concluded that a rule limiting the total number of times each NCAA college football team could televise its games constituted a “naked restriction on price or output” because “[p]rice is higher and output lower than they would otherwise be, and both are unresponsive to consumer preference.” Id. at 107, 109.

As defendants, Hospitals A and B would face a “heavy burden of establishing an affirmative defense which competitively justifies this apparent deviation from the operations of a free market.”139Id. at 113; see also FTC v. Ind. Fed’n of Dentists, 476 U.S. 447, 459 (1986) (“Absent some countervailing procompetitive virtue[,] . . . such an agreement limiting consumer choice by impeding the ‘ordinary give and take of the market place,’ cannot be sustained under the Rule of Reason.” (citation omitted)).
To do so, they would need to show that the religious rider is an ancillary restraint and therefore exempt from the per se rule.140“If the joint venture integrates production or distribution, then agreements to restrict output or raise prices are still illegal per se unless the defendants can show that the challenged agreement is essential to the functioning of the venture.” Hovenkamp, supra note 122, at 78.
Under the ancillary restraints doctrine, a horizontal agreement can be exempt from the per se rule if it meets two requirements: “(1) [it is] ‘subordinate and collateral to a separate, legitimate transaction,’ . . . and (2) [it is] ‘reasonably necessary’ to achieving that transaction’s pro-competitive purpose.’ 141Aya Healthcare Servs. v. AMN Healthcare, Inc., 9 F.4th 1102, 1109 (9th Cir. 2021) (first quoting Rothery Storage & Van Co. v. Atlas Van Lines, Inc., 792 F.2d 210, 224 (D.C. Cir. 1986); and then United States v. Addyston Pipe & Steel Co., 85 F. 271, 281 (6th Cir. 1898)).
If the restraint meets these two conditions, it is analyzed under the rule of reason, which, as explained above, involves a fact-specific inquiry to determine if the restraint’s procompetitive effects outweigh its anticompetitive effects.142Id.; see supra note 108 and accompanying text.

Here, the crux of the matter is whether the religious rider is “reasonably necessary” to achieve the collaboration’s asserted procompetitive effects: higher quality care and lower costs at both hospitals. Hospital A and Hospital B would presumably argue that the agreement is reasonably necessary. And we might expect the argument to go something like this: Hospital A operates in the market as a Catholic hospital. Because of this, it can collaborate only under certain conditions—that is, ones that do not give rise to “scandal.”143 U.S. Conf. of Cath. Bishops, supra note 36, at 24.
Therefore, in order for it to collaborate with a secular hospital, it must secure an agreement from that hospital that it too will operate in the market as a Catholic hospital (i.e., follow the Directives). Otherwise, the collaboration cannot take place. Put differently, Hospital A and Hospital B might argue that the religious rider is reasonably necessary to achieve the procompetitive benefits of the larger collaboration because Hospital A simply won’t collaborate without such a rider. Either the religious rider is permitted or the procompetitive benefits of the larger collaboration (which we assume have been proven) will not be achieved.

From one perspective, this argument makes sense. If one hospital would not enter a collaboration without this religious rider, isn’t the religious rider therefore reasonably necessary to achieve the collaboration’s procompetitive effects? In support of this intuition, Hospitals A and B might point to the Seventh Circuit’s often-cited decision in Polk Bros. v. Forest City Enterprises.144Polk Bros. v. Forest City Enters., 776 F.2d 185, 189 (7th Cir. 1985).
The Seventh Circuit expanded on Polk Bros. in Blackburn v. Sweeney, explaining that “courts must look to the time an agreement was adopted in assessing its potential for promoting enterprise and productivity.”145Blackburn v. Sweeney, 53 F.3d 825, 828 (7th Cir. 1995).
If the agreement promoted enterprise and productivity when it was adopted, the restraint is properly characterized as ancillary, not naked.146Polk Bros., 776 F.2d at 189.
And this, the two hospitals would argue, is the case with respect to the religious rider.

But this argument is highly problematic. First, this argument boils down to an assertion that the output restriction is reasonably necessary because the parties say it is. But antitrust law does not permit defendants to simply assert that certain anticompetitive agreements are necessary; when determining whether an otherwise per se illegal agreement is reasonably necessary to achieve the procompetitive effects of a larger agreement, courts pressure test the arguments put forth by conducting “an inherently fact-specific inquiry” to determine whether cooperation would have been possible absent the challenged restraint.147See Snow v. Align Tech., Inc., 586 F. Supp. 3d 972, 979 (N.D. Cal. 2022); Aya Healthcare Servs. v. AMN Healthcare, Inc., 9 F.4th 1102, 1110 (9th Cir. 2021); Polk Bros., 776 F.2d at 190.
For instance, when considering whether a non-solicitation agreement between two healthcare staffing agencies was reasonably necessary, the Ninth Circuit concluded that the answer was yes because the non-solicitation agreement ensured that one of the healthcare firms could provide spillover assignments to the other without endangering its own ability to supply hospitals.148Aya Healthcare, 9 F.4th at 1110. In contrast, the district court in Snow v. Align Technology, Inc. concluded that the plaintiffs had plausibly alleged that the challenged restraint was not reasonably necessary for the cooperative undertaking due to the power imbalance between the parties. Snow, 586 F. Supp. 3d at 980.
Other courts have recognized that certain anticompetitive restraints may be reasonably necessary to the success of a joint venture because they alleviate concerns about free-riding,149Rothery Storage & Van Co. v. Atlas Van Lines, Inc., 792 F.2d 210, 221 (D.C. Cir. 1986); Med. Ctr. at Elizabeth Place, LLC v. Atrium Health Sys., 922 F.3d 713, 730 (6th Cir. 2019). As Areeda and Hovenkamp note,

joint venturers may have quite legitimate reasons for restraining members’ competitive business outside the venture. Most such concerns apply to some variation of the free rider problem. Basically, the venture must have some way of protecting the intellectual property, trade secrets and other learning of the venture from being used in competition with the venture itself. If such protection is insufficient, the venture will be deterred from forming in the first place.

protect trade secrets,150In re HIV Antitrust Litigation, 656 F. Supp. 3d 963, 994–95 (N.D. Cal. 2023).
or permit a new product to be sold.151See Broad. Music, Inc. v. CBS, Inc., 441 U.S. 1, 23 (1979).
Here, however, the agreement to limit output at the secular hospital serves no purpose beyond making cooperation religiously palatable to Hospital A.

Second, federal enforcers have long maintained that “if the participants [to a collaboration] could achieve an equivalent or comparable efficiency-enhancing integration through practical, significantly less restrictive means, then . . . the agreement is not reasonably necessary.”152FTC & U.S. Dep’t of Just., Antitrust Guidelines for Collaborations Among Competitors 9 (2000), https://www.ftc.gov/sites/default/files/documents/public_events/joint-venture-hearings-antitrust-guidelines-collaboration-among-competitors/ftcdojguidelines-2.pdf [perma.cc/R5Q7-JSH9]. Some courts have held that consideration of less restrictive alternatives is appropriately reserved for a rule of reason analysis, not the ancillary restraints analysis. E.g., In re HIV Antitrust Litigation, 656 F. Supp. 3d at 994 n.23. Yet even these courts have not simply accepted defendants’ claims that a restraint is reasonably necessary, and they have required that defendants provide some plausible, economic-based rationale such as preventing free riding or protecting proprietary information. Id. at 99.
Supreme Court case law supports this reasoning. In NCAA v. Board of Regents, for instance, the Court explained that the NCAA’s efficiency justification for limiting member schools’ ability to televise their football games failed because NCAA football could be marketed just as effectively without the restrictive television plan.153NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 114 (1984).
Here, the hospitals’ argument should fail for the same reason: The two hospitals could achieve the same procompetitive efficiencies of the larger collaboration without the output restriction. Further, there is considerable evidence that there are, in fact, less restrictive (and religiously palatable) alternatives to a flat output restriction at the secular hospital. In past religious-secular collaborations and mergers, the parties have instituted “religious firewalls” (i.e., structural remedies) to ensure the secular partner can provide care while making sure that Catholic hospital employees, funds, and facilities are not used to provide impermissible care. 154Durand, supra note 17, at 2623–29; Carol S. Weisman, Kaiser Family Foundation, Is There a Common Ground? Affiliations Between Catholic and Non-Catholic Health Care Providers and the Availability of Reproductive Health Services 15–17 (1997), https://www.kff.org/womens-health-policy/is-there-a-common-ground-affiliations-between [perma.cc/3JEA-4V9D].
And, at times, the parties have gotten quite creative, such as by creating a “hospital within a hospital.”155Durand, supra note 17, at 2624.
Antitrust law has no problem with such institutional practices and, in fact, would encourage them if they allow procompetitive collaborations that might not otherwise occur.

Third, this argument goes directly against a core pillar of modern antitrust law, namely, the principle that social justifications for anticompetitive conduct are not cognizable.156NCAA v. Alston, 141 S. Ct. 2141, 2167 (2021).
Although the hospitals may couch the religious rider in economic terms by arguing that it is reasonably necessary to obtain procompetitive efficiencies, this does not change the fact that the first-order reason for the restraint is a matter of faith. Hospital A will not cooperate with Hospital B if Hospital B provides certain services under certain conditions because Hospital A believes that providing those services to consumers is immoral. More specifically, Hospital A fears that by collaborating with or selling to a firm that provides these services, it may give rise to scandal—that is, lead observers to conclude that it views the sale of these services to be permissible.157 U.S. Conf. of Cath. Bishops, supra note 36, at 24 (“The cooperation of a Catholic institution with other health care entities engaged in immoral activities, even when such cooperation is morally justified in all other respects, might, in certain cases, lead people to conclude that those activities are morally acceptable. This could lead people to sin.”).

This amounts to a social justification for anticompetitive behavior, a defense that has been rejected time and time again by the Supreme Court.158See, e.g., FTC v. Superior Ct. Trial Laws. Ass’n, 493 U.S. 411, 424 (1990); FTC v. Ind. Fed’n of Dentists, 476 U.S. 447, 459 (1986); FTC & U.S. Dep’t of Just., supra note 152, at 9 (“Some claims—such as those premised on the notion that competition itself is unreasonable—are insufficient as a matter of law . . . .”).
Moreover, the Court has also made clear that firms are not entitled, through anticompetitive agreements, “to pre-empt the working of the market by deciding for [themselves] that [their] customers do not need that which they demand.”159Ind. Fed’n of Dentists, 476 U.S. at 462.
Thus, while it is perfectly fine for a Catholic hospital to believe that the market should not provide certain services, arguments based on an assumption that competition for particular services is undesirable are precluded under the Sherman Act.160Nat’l Soc’y of Pro. Eng’rs v. United States, 435 U.S. 679, 695 (1978) (“Even assuming occasional exceptions to the presumed consequences of competition, the statutory policy precludes inquiry into the question whether competition is good or bad.”).
This is because “[t]he heart of our national economic policy long has been faith in the value of competition.”161Standard Oil Co. v. FTC, 340 U.S. 231, 248 (1951).
Antitrust law assumes that “all elements of a bargain—quality, service, safety, and durability—and not just the immediate cost, are favorably affected by the free opportunity to select among alternative offers.”162Nat’l Soc’y of Pro. Eng’rs, 435 U.S. at 695 (emphasis added).
And the Court has made clear that this reasoning applies to all products in the market, including those that some may believe to be harmful.163Id. (“Exceptions to the Sherman Act for potentially dangerous goods and services would be tantamount to a repeal of the statute.”).

Now, it is possible that the defendant hospitals might make a different sort of argument under the ancillary restraint doctrine. The parties might argue that Hospital B’s cessation of various service lines is necessary to avoid inefficiencies stemming from an attempt to integrate reproductive care across the secular and religious hospitals. And, indeed, attempts to adhere to the Directives while maintaining care have caused inefficiencies in past collaborative agreements among Catholic and secular entities. For example, after the local bishop of one Catholic hospital learned that sterilizations were taking place in the hospital, something the bishop saw as violating the Directives, the Catholic hospital sold one individual operating room to a nonreligious clinic.164Stulberg et al., supra note 12, at 425–26.
As a result:

[T]here were two consent forms: one consent form for the cesarean section on Saint P’s Hospital paper, and then a separate consent form which was the clinic paper for the tubal ligation. And then the biggest step . . . was that [hospital] staff cannot be, in any way, shape, or form, involved in the case. They can’t be at the OR table, they can’t start the case, they can’t participate in the c-section—in any way, at all—if there will be a tubal ligation.165Id. at 426 (second alteration in original).

Such restrictions on staffing and operations ultimately lowered the quality of care, as one physician explained:

[I]t’s vastly complicated, but I’ll keep it only stupidly complicated. All c-sections between 7:00a.m. and 5:00p.m. are staffed by clinic ambulatory surgery personnel, whether they need a tubal or not. And after 5:00p.m., we try and maintain a call team of ambulatory surgery personnel that will come in from outside the hospital to cover the c-sections that require tubals. . . . We have not been able to maintain a call team for every night, and weekend. So, at this point, we have maybe 60% of the nights and weekends covered. So . . . if you want your tubes tied, you’re basically playing, you know, Russian Roulette as to whether you’ll get your operation done.166Id. at 425.

In response, Hospitals A and B might argue that, absent Hospital B’s agreement to limit output, adherence to the Directives would limit the ability of the parties to fully integrate administrative and financial processes. The parties will have to devise inefficient workarounds to allow Hospital B to provide services in a way that allows Hospital A to comply with the Directives, workarounds that harm patient care.

But such an argument holds no water under the antitrust laws. Anticompetitive ancillary restraints are permissible only when they are necessary to achieve efficiencies, not to avoid self-imposed inefficiencies.167Broad. Music, Inc. v. CBS, Inc., 441 U.S. 1, 19–21 (1979) (setting of price “necessary” for the blanket license).
Such an argument would in fact make clear, as noted earlier, that there are practical, significantly less restrictive means for achieving the overall collaboration that do not require a total cessation of services at the secular institution.168See Arizona v. Maricopa Cnty. Med. Soc’y, 457 U.S. 332, 352–53, 356–57 (9th Cir. 1982) (scrutinizing the defendant medical foundations for indicia of integration and evaluating the record evidence regarding less restrictive alternatives). Note that it would be procompetitive were a Catholic hospital to partner with a secular hospital to design mechanisms by which patients who were denied care at the Catholic hospital (for religious reasons) could easily transfer to a corresponding provider at the secular hospital.

The argument that a religiously motivated output restriction is necessary to effectuate the collaboration’s procompetitive benefits should therefore fail. But note that if the joint venture itself, without output restriction, has been proved to be otherwise procompetitive, the joint venture should be left intact. And if the parties propose religious “firewalls” in the absence of the output restriction, courts should be receptive to such “firewalls” as long as they do not restrict the ability of the secular hospital to compete as an independent market actor in its own facilities.

* * *

The restraint described above constitutes a naked restraint on trade that is not reasonably necessary to achieve procompetitive benefits. Instead, it exists for purely social, faith-based reasons. As such, it violates Section 1 of the Sherman Act, and courts should enjoin the restraint.

2. Agreements to Restrict Output Post-Sale

I next consider religious post-sale restrictions on hospitals. As noted earlier, Catholic hospitals and systems sometimes require secular buyers to agree to adhere to the Directives—for decades and sometimes even in perpetuity—when purchasing a Catholic hospital. As with religious-secular competitor collaborations involving output restrictions, these restrictions are often justified as legitimate efforts to promote the Catholic healthcare mission.169Joyce Carr, California Says Catholic Hospitals Can’t Stipulate How They’re Sold, Nat’l Cath. Reg. (Aug. 17, 2003), https://www.ncregister.com/news/california-says-catholic-hospitals-cant-stipulate-how-theyre-sold [perma.cc/433J-HN5X].

But we should suspect that such agreements also lead to anticompetitive market effects. Requiring a secular buyer to comply with the Directives means, in practical terms, that a competitor has agreed to substitute its judgement as to what services to sell, and under what circumstances, for that of another market actor—a market actor that has exited the market. This seems problematic from an antitrust viewpoint, since antitrust law is motivated by the belief that agreements which “deprive[] the marketplace of the independent centers of decisionmaking that competition assumes and demands” are “fraught with anticompetitive risk.”170Copperweld Corp. v. Indep. Tube Corp., 467 U.S. 752, 768–69 (1984). This, of course, was true for the religious-secular competitor collaboration scenario as well.
So let us consider the potential anticompetitive effects of such an agreement and whether they might be justified by some procompetitive outcome. Again, for analytical clarity, I use a stylized hypothetical to guide the discussion:

Hospitals A, B, and C are the only three hospitals in County D. Hospital A is a Catholic hospital and structures its provision of reproductive healthcare according to the Directives. Hospitals B and C are secular hospitals which provide a full range of reproductive healthcare services. The owners of Hospital A enter into an agreement to sell Hospital A to a secular buyer that seeks to enter the market in County D. As part of the sale agreement, the secular buyer agrees to continue adhering to the Directives in perpetuity at Hospital A, even though it holds no moral opposition to Directive-prohibited healthcare services and would otherwise provide them.

As a starting point, the first-order effect of this agreement is an artificial suppression of output. By agreeing to adhere to the Directives, the secular buyer has agreed not to expand the types of services it will provide to the community (in vitro fertilization, elective abortions) or expand output in an existing service line (miscarriage care, contraception, sterilization) regardless of market demand or profitability.171“A refusal to compete with respect to the package of services offered to customers, no less than a refusal to compete with respect to the price term of an agreement, impairs the ability of the market to advance social welfare . . . .” FTC v. Ind. Fed’n of Dentists, 476 U.S. 447, 459 (1986).
And it has agreed to refrain from doing so in perpetuity. Thus, although one might expect that the sale of Hospital A to a secular buyer would lead to an increase in services and market competition,172Were it not for the agreement, the secular buyer would be incentivized to provide the full spectrum of reproductive healthcare. Its entrance into the market would in turn increase the competitive pressures on Hospitals B and C in terms of price and quality.
this does not occur because the secular buyer has contracted away its right to fully compete in various service lines, regardless of consumer demand. In other words, the restraint “reduc[es] the importance of consumer preference in setting . . . output” and constrains the buyer’s freedom to compete in the market.173NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 107 (1984).
The second-order effect of this agreement is that the price for reproductive services in the market will be artificially inflated. Were it not for the agreement, the secular buyer would be incentivized to provide the full spectrum of reproductive care under just as many circumstances as Hospitals B and C are willing to provide such care. That is, were it not for the agreement, the market would see an increase in competition among Hospitals A, B, and C, which should have a downward impact on price.

Thus, just as with the religious rider in the competitor collaboration scenario, the religious rider in the hospital sale scenario leads to clear and serious anticompetitive effects in the market. The entrance of the secular buyer should increase output and decrease price, but these effects are stymied because the religious rider stays Hospital A’s new owner. The religious rider, in other words, acts like an agreement not to compete because it prevents the new owner from fully and freely competing in the market. The question then becomes: Are there any procompetitive justifications for this religious rider?

We might imagine that Hospital A’s seller would argue that the religious rider is ultimately procompetitive because it is reasonably necessary to achieve some other procompetitive effect. Here, the owner of Hospital A might argue that it would not sell Hospital A to a secular buyer without the religious rider, and thus the relevant procompetitive benefit is the sale of the hospital itself.

Now, at a high level, this argument makes some sense if we think about antitrust law’s approach to noncompetes in the business-sale context. Although agreements not to compete have long been prohibited under antitrust doctrine,174“It must be remembered that restrictive covenants are restraints of trade” and that “[t]he law looks unfavorably towards such restraints.” Laidlaw, Inc. v. Student Transp. of Am., Inc., 20 F. Supp. 2d 727, 757 (D.N.J. 1998).
noncompetes in the context of a business sale are an established exception to the general rule.175Section 1 of the Sherman Act has never been found to prohibit such agreements when they are reasonably limited in duration and geography. See, e.g., Frackowiak v. Farmers Ins. Co., 411 F. Supp. 1309, 1318 (D. Kan. 1976).
The reasoning for such an exception is essentially the ancillary restraint doctrine: The law recognizes that a noncompete agreement might sometimes be necessary to effectuate the sale of a business.176Bus. Elecs. Corp. v. Sharp Elecs. Corp., 485 U.S. 717, 729 n.3 (1988) (“The classic ‘ancillary’ restraint is an agreement by the seller of a business not to compete within the market.”).

In the classic scenario of a business sale, the noncompete provision is believed to be reasonably necessary for two reasons. First, and most importantly, it assures the buyer that the seller will not simply set up shop down the street and take all her old customers with her, thereby undermining the value of the buyer’s purchase.177“A covenant ancillary to the sale of a business ensures the buyer that the former owner will not walk away from the sale with the company’s customers and goodwill, leaving the buyer with an acquisition that turns out to be only chimerical.” Smith v. Burkitt, 795 N.E.2d 385, 390 (Ill. App. Ct. 2003).
Without such assurance, a buyer might not be willing to make the purchase, and the sale would not take place. Second, the noncompete agreement also enables the seller to sell her business at its fair value. Without the ability to agree not to compete, a business seller may not be able to obtain the true value of her business in a sale because potential buyers fear she will undercut the value of their purchase by competing post-sale.178“[A] man . . . should be at liberty to sell . . . in the most advantageous way in the market; and in order to enable him[,] . . . it is necessary that he should be able to preclude himself from entering into competition with the purchaser.” Budget Rent-A-Car Corp. of Am. v. Fein, 342 F.2d 509, 515 n.12 (5th Cir. 1965) (quoting Orkin Exterminating Co. of S. Ga. v. Dewberry, 51 S.E.2d 669 (Ga. 1949), overruled by, Barry v. Stanco Commc’ns Prods., Inc., 252 S.E.2d 491 (Ga. 1979)); see also Hudgins v. Amerimax Fabricated Prods., Inc., 551 S.E.2d 393, 396 (Ga. Ct. App. 2001).

However, because the default assumption is that noncompete agreements are prohibited,179Laidlaw, 20 F. Supp. 2d at 757.
a noncompete to the sale of a business must be reasonable and limited in scope.180See, e.g., Jewel Box Stores Corp. v. Morrow, 158 S.E.2d 840, 843 (N.C. 1968).
Determining whether a noncompete is reasonable is a matter of state law. In general, state courts will enforce an agreement not to compete in the context of a business sale “(1) if it is reasonably necessary to protect the legitimate interest of the purchaser; (2) if it is reasonable with respect to both time and territory; and (3) if it does not interfere with the interest of the public.”181Id.; see, e.g., Beverage Sys. v. Beverage Repair, 784 S.E.2d 457, 461 (N.C. 2016) (holding that a noncompete’s geographical restriction covering areas in which the prior owner had never conducted business was unreasonably broad).
Noncompetes generally fail on either prong (1) or (2), as the enforcement of a reasonable contract designed to enable the sale of a business is considered in the public’s interest.182See, e.g., Hudgins, 551 S.E.2d at 394 (remanding for determination of a more restrictive territory); Beverage Sys., 784 S.E.2d at 462 (refusing to amend the overly broad restrictive covenant and rendering it unenforceable); Budget Rent-A-Car Corp. of Am., 342 F.2d at 515 n.12; Lexis-Nexis v. Beer, 41 F. Supp. 2d 950, 959 (D. Minn. 1999) (reasoning that enforcing the noncompete will “serve the public interest by ensuring that reasonable agreements are enforced to protect a business’s hard-earned good will”).

However, when we apply the traditional analysis to a religious, post-sale noncompete on a secular buyer, the traditional justifications for allowing a noncompete in a business sale start to fall apart. First, of course, is the fact that the agreement here requires compliance in perpetuity. While noncompetes in the sale of a business have been allowed to protect the purchaser’s legitimate interest, they have never been allowed to exist in perpetuity.183See, e.g., Crye Precision LLC v. Bennettsville Printing, 755 F. App’x 34, 36–37 (2d Cir. 2018) (noting that a noncompete without temporal or geographic limitations goes far beyond what courts have deemed to be reasonable).
So, right off the bat, requiring Hospital A to refrain from fully competing in the markets for reproductive healthcare services in perpetuity would be a grave cause of concern from an antitrust perspective. At the very least, a court would find that the agreement’s duration is unreasonable and strike that provision.184This would also be true for a provision that required compliance for two decades, as was the case when Tenet Healthcare purchased the Queen of Los Angeles/Hollywood Presbyterian Medical Center in 1998. Fogel, supra note 36, at 4.
Second, from a geographic perspective, the restraint makes no sense given that the seller has exited the market.

But the problems in the seller’s argument go deeper than this because the core justifications for allowing noncompetes in the sale context do not apply here. First, business-sale noncompetes have traditionally been allowed to protect the buyer’s legitimate interest by limiting the seller’s ability to compete post-sale.185See, e.g., Am. Control Sys., Inc. v. Boyce, 694 S.E.2d 141, 145 (Ga. Ct. App. 2010); Kladis v. Nick’s Patio, Inc., 735 N.E.2d 1216, 1220 (Ind. Ct. App. 2000) (“Generally, the agreement attempts to preserve a business’s ‘goodwill’ for the buyer.”).
The law accepts that a seller might not be able to find a buyer for her business if she cannot promise the buyer that she will not immediately lure all her old customers to a new shop. But in the example above, this logic does not hold. The religious rider does nothing to protect the buyer’s legitimate interests; the secular buyer would gladly purchase the hospital without the religious rider. Instead, the religious rider is protecting the seller’s interest in ensuring that certain services not be sold in the market because the seller believes it is immoral to provide and consume them. But this interest is not legitimate (i.e., cognizable) under the antitrust laws.186Nicole Garnette and Patrick Reidy have argued that religious restrictions in business sales can functionally resemble noncompetes in that they protect the “reputation” of the faith community: “When faith communities impose restrictions prohibiting their former property from being identified as [religious], they seek to ensure that future uses remain publicly disaffiliated from their religious organization.” Nicole Stelle Garnett & Patrick E. Reidy, Religious Covenants, 74 Fla. L. Rev. 821, 853–54 (2022). Doing so protects the “goodwill” of the faith community, just as a traditional noncompete protects the “goodwill” of the business to be sold. However, such restraints are very different from the one analyzed here because they still “allow[] future purchasers full of use of their property—limiting them only in their desire to expressly identify their property with its former owner.” Id. at 854.

Second, in the traditional noncompete scenario, the restraint on competition works to ensure that the buyer obtains the full value of the business while also protecting the seller’s ability to sell at full price.187Mohr v. Bank of N.Y. Mellon Corp., 371 F. App’x 10, 16 (11th Cir. 2010); see also Presto-X-Co. v. Beller, 568 N.W.2d 235, 238 (Neb. 1997) (“Nebraska has recognized the legitimate need of one who purchases a business to reasonably protect himself against competition from the seller.”).
But a restriction on the new owner’s ability to compete post-sale should undermine the value of the sale. 188A healthcare business that is limited from competing fully in the market is akin to a bird with its wings clipped. It cannot respond appropriately to the change in market currents.
After all, most buyers want to be able to use their new property as they see fit.189Nor would we assume that the buyer’s decision to enter new service lines (or begin producing more output in existing service lines) post-sale undermines the value of the business it now owns.
And evidence suggests that buyers who commit to the continuation of religious restrictions have received a discount in past sales.190Sepper, supra note 16, at 941–42; Paul Gertler & Jennifer Kuan, Does It Matter Who Your Buyer Is? The Role of Nonprofit Mission in the Market for Corporate Control of Hospitals, 52 J.L. & Econ. 295, 302 (2009).

Now, of course, business sellers are entitled to sell their businesses for less money than the market might demand. Antitrust law doesn’t prevent this (absent an anticompetitive restraint). The key point here is that restraining a buyer’s ability to compete is not necessary for the seller to receive the full market value of its business. That is, it is not ancillary to the sale’s larger procompetitive purpose. Thus, the second main justification for deviating from the law’s antipathy towards noncompetes in the context of a business sale—protecting the sale value—does not hold when a noncompete is imposed on the buyer as opposed to the seller.

For these reasons alone, any plaintiff challenging the agreement has a strong argument that the agreement is not reasonably necessary to achieve the larger procompetitive effects of the sale. To find otherwise would require a court to invert the traditional analysis governing noncompetes in the business-sale context. But a plaintiff might further support its claim by focusing on the public interest prong of the traditional test. While the public interest prong rarely plays a decisive role in the traditional noncompete analysis,191Stormans, Inc. v. Selecky, 586 F.3d 1109, 1138–39 (9th Cir. 2009) (“When the reach of an injunction is narrow, limited only to the parties, and has no impact on non-parties, the public interest will be ‘at most a neutral factor in the analysis rather than one that favor[s] [granting or] denying the preliminary injunction.’ ” (alteration in original) (quoting Bernhardt v. Los Angeles Cnty., 339 F.3d 920 (9th Cir. 2003)).
it is considerably more forceful when the subject of analysis is a religiously motivated noncompete imposed on a secular healthcare buyer. First, in the most general of terms, it is clearly in the public’s interest that there be a thriving, competitive market for healthcare services.192Several courts have held that enforcing a noncompete provision in the healthcare context is against the public interest. See, e.g., Murfreesboro Med. Clinic, P.A. v. Udom, 166 S.W.3d 674, 679, 683 (Tenn. 2005) (“Having a greater number of physicians practicing in a community benefits the public by providing greater access to health care. Increased competition for patients tends to improve quality of care and keep costs affordable.”); Southernmost Foot & Ankle Specialists, P.A. v. Torregrosa, 891 So. 2d 591, 595 (Fla. Dist. Ct. App. 2004) (affirming lower court’s decision that it was against the public interest to enforce a noncompete provision against the only podiatrist with staff privileges in the community).
Courts should be suspicious of sale agreements that prevent healthcare entities from providing a comprehensive range of services to the community.193See Murfreesboro Med. Clinic, 166 S.W.3d at 679.
These agreements effectively act as barriers to entry and deprive communities of the benefits that flow from increased competition in the healthcare space. And under the terms of the sale agreement, the buyer of Hospital A would be prohibited from adding reproductive services even if Hospitals B and C shut down and Hospital A was the sole source of healthcare for the entire community.

Second, while religious institutions and providers generally have a right to unilaterally refuse to provide treatments that conflict with their religious beliefs,194See supra note 93 and accompanying text.
it is against the public interest to allow religious institutions and providers to impose through contract these care restrictions on secular providers, just as it is against the public interest to allow secular providers to contract away their ability to fully compete. Doing so denies the community the benefits that accrue from an otherwise willing provider (competitor) entering the market,195Banning such post-sale noncompetes is always in the public interest, but it is especially crucial when a community’s only hospital is involved. Without local secular options, patients often must travel far for comprehensive reproductive care. A Catholic hospital sale offers a key chance to expand local services.
thereby forestalling an increase in competition (and lower prices) and consumer choice.196Prohibiting such agreements does nothing to prevent religious consumers from receiving healthcare in accordance with their values. “From the standpoint of secular obstetric ethics, physicians are obligated to provide care with respect for a woman’s autonomy, acting in her best interest at all times, and acting in the best interest of the fetus conditional on the pregnant woman’s wishes.” Freedman & Stulberg, supra note 14, at 2 (emphasis added). This means that a woman may choose not to receive treatment to which she has a moral objection.

Note, of course, that nothing under Section 1 prevents a Catholic hospital from deciding to sell only to a Catholic buyer whom it trusts to follow the Directives unilaterally. Nor does Section 1 prohibit a secular buyer from voluntarily and unilaterally deciding that it would like to see how profitable it would be to continue operating under the Directives. If there is value in it, the buyer will be prompted to continue adhering to Catholic doctrine voluntarily. In contrast, if the value that accrues from possessing a Catholic identity and complying with the Directives is not large enough, the buyer will act accordingly. The problem arises when the buyer and seller enter into an agreement that removes the buyer’s independent decisionmaking ability to act as it chooses. Such an outcome is “not consistent with [the] fundamental goal of antitrust law.”197NCAA v. Bd. of Regents of the Univ. of Okla., 468 U.S. 85, 107 (1984).

* * *

The restraint described above is wholly different from the typical sort of noncompete agreement that courts have analyzed in the context of a business sale. It does nothing to protect a buyer’s legitimate interest and instead acts as a barrier to entry across multiple service lines, thereby depriving the public of greater output and lower prices—the goods of increased competition. Put differently, it is an unreasonable restraint on trade, one whose anticompetitive effects are not outweighed by any procompetitive benefits. As such, it runs afoul of Section 1 of the Sherman Act.

B. A Religious Exemption to the Sherman Act?

Courts have not considered whether religiously motivated output restrictions—in the context of a competitor collaboration or sale—violate the antitrust laws. It does not appear that any such restriction has been challenged under Section 1 of the Sherman Act.198A Westlaw search for cases dealing with the intersection of antitrust law and free exercise rights resulted in only two results. See Proctor v. Gen. Conf. of Seventh-Day Adventists, 651 F. Supp. 1505 (N.D. Ill. 1986); Costello Publ’g Co. v. Rotelle, 670 F.2d 1035 (D.C. Cir. 1981). Both cases involved the distribution of religious literature. In Proctor, the district court concluded that the plaintiff’s antitrust claims failed because the Sherman Act did not apply, given the facts of the case, to the colporteur ministry or distribution systems established for the purposes of evangelism. Proctor, 651 F. Supp. at 1524. In Costello, the D.C. Circuit rejected the possibility of a blanket religious exemption to the Sherman Act and held that “in every case, the court must carefully assess the nature and extent of the antitrust violations, including their market impact, against the religious goal sought to be implemented before deciding” whether the challenged activities fell outside the scope of the Sherman Act. Costello, 670 F.2d at 1050.
As Catholic doctrine’s reach into secular institutions clashes with reproductive healthcare advocates’ desperation to preserve access, the potential for litigation is ripe. Although I hope that the previous Sections have shown why these suits should succeed under Section 1, I will spend a bit more time here developing the doctrinal case for denying a religious exemption under Section 1 of the Sherman Act.

To start, it may be helpful to again emphasize what the Sherman Act does not do. The Sherman Act does not require Catholic hospitals (or any hospital) to provide particular services to the public. Nor does the Sherman Act require Catholic hospitals (or any hospital) to collaborate with or sell to a particular market actor.199The default rule is that a firm can lawfully refuse to deal with rivals, so long as this choice is unilateral. However, under Section 2 of the Sherman Act, a dominant firm’s refusal to deal with rivals becomes unlawful when it operates to monopolize the market through exclusion. See Verizon Commc’ns Inc. v. Law Offs. of Curtis V. Trinko, LLP, 540 U.S. 398, 408 (2004).
Business decisions regarding what products or services to sell, as well as what entities to collaborate with or sell to, are to be made at the discretion of each individual firm according to its own profit-maximizing calculus.

In addition, the Sherman Act takes no issue with the growth in facilities operating under Catholic doctrine when that growth does not take place through anticompetitive means.200See United States v. Grinnell Corp., 384 U.S. 563, 570–71 (1966); Standard Oil Co. v. FTC, 340 U.S. 231, 248 (1951) (“The heart of our national economic policy long has been faith in the value of competition.”).
Imagine, for instance, that a Catholic hospital and secular hospital chose to enter into a joint venture to create a clinic serving prenatal and postpartum clients. Even if this new clinic operated under the Directives—and thus provided no abortion services or contraceptive services—the Sherman Act would likely view this collaboration in a favorable light. After all, by collaborating, the two firms expanded output in the community. Similarly, imagine that a buyer in the market wants to purchase a Catholic hospital and continue operating it under Catholic doctrine because she believes that is the most profitable course of action.201Antitrust takes no issue with this scenario, as long as the buyer retains the ability to change her mind and expand output if she so desires.
The Sherman Act again takes no issue with this.202Moreover, antitrust takes no issue with a state deciding to allow an otherwise anticompetitive joint venture (or sale) between a Catholic and secular facility to take place. The state action doctrine allows states to displace competition in pursuit of other goals. Parker v. Brown, 317 U.S. 341, 350–52 (1943). Otherwise anticompetitive action may therefore be protected from antitrust scrutiny if (1) the challenged restraint has been clearly articulated and affirmatively expressed by state policy, and (2) the policy is actively supervised by the state itself. Cal. Retail Liquor Dealers Ass’n v. Midcal Aluminum, Inc., 445 U.S. 97, 105 (1980). Thus, some states have passed Certificate of Public Advantage (COPA) laws, which provide antitrust immunity to hospital mergers and collaborations that would otherwise be illegal. Christopher Garmon & Kishan Bhatt, Certificates of Public Advantage and Hospital Mergers, 65 J.L. & Econ. 465, 466 (2022). Nothing prohibits firms from seeking a COPA certificate in the context of a religious-secular collaboration; whether that certificate would be granted, of course, depends on the state’s own calculus.

The problem arises—from an antitrust perspective—when religious firms seek to dictate through contract the market behavior of other firms in ways that harm consumers.203“[I]t is not antitrust’s purpose to regulate markets but only to see that unrestrained alternatives emerge.” Hovenkamp, supra note 122, at 43.
In the restraints examined above, a religious firm is not simply asserting its own right to sell only those services it deems legitimate or to collaborate only with those firms it finds morally suitable; it is also seeking to control the market decisions of another, independent firm.

Courts should firmly resent any inclination to treat such restraints as permissible simply because of their religious gloss. First, if taken at face value, the hospitals’ argument in both the competitor-collaboration and sale context (i.e., that the religious rider is ancillary to a larger, procompetitive agreement) appears to result in a blanket religious exemption to the ancillary restraint doctrine. As noted earlier, when determining whether an otherwise per se illegal agreement is reasonably necessary to achieve the procompetitive effects of a larger agreement, courts carefully evaluate the arguments put forth by the parties to determine whether cooperation would have been possible absent the challenged restraint.204See, e.g., Snow v. Align Tech., Inc., 586 F. Supp. 3d 972, 979–80 (N.D. Cal. 2022); Aya Healthcare Servs. v. AMN Healthcare, Inc., 9 F.4th 1102, 1110 (9th Cir. 2021); Polk Bros. v. Forest City Enters., 776 F.2d 185, 190 (7th Cir. 1985).
But if antitrust law were to allow a firm to justify an ancillary restraint based on a religious belief, a court’s ability to interrogate the veracity of this assertion becomes murky. The Constitution rightly bars Courts from questioning whether the religious beliefs of an individual—or a firm—are “true.”205See United States v. Ballard, 322 U.S. 78, 86 (1944).
So, faced with the claim that a religious hospital is prohibited, by the terms of its faith, from engaging in a collaboration or selling a hospital without imposing a religious restriction, a court may well feel forced to simply accept the business agreement. And this would seem to relieve religious firms of the burden to prove that an otherwise anticompetitive restraint is reasonably necessary to achieve procompetitive effects.206The Areeda-Hovenkamp treatise explains that the burden of justification for a trade restraint is to show that it has a competitively legitimate objective and serves that objective. See 7 Phillip E. Areeda & Herbert Hovenkamp, Antitrust Law: An Analysis of Antitrust Principles and Their Application ¶¶ 1505, 1505a, at 428–33.
Put simply, while antitrust law does not allow firms to claim that anticompetitive behavior is reasonably necessary simply because the firms say it is so, this is what would likely occur if antitrust law were to treat religious justifications as cognizable.

Second, in arguing that the output restriction in reproductive service lines is necessary to achieve procompetitive gains in other service lines, the parties seek to trade off the welfare of one consumer group (primarily composed of women) with that of another. But the Sherman Act does not protect only certain market participants; it “protect[s] all who are made victims of the forbidden practices by whomever they may be perpetrated.”207Mandeville Island Farms, Inc. v. Am. Crystal Sugar Co., 334 U.S. 219, 236 (1948) (emphasis added).
And the Supreme Court has made clear that “[i]f a decision is to be made to sacrifice competition in one portion of the economy for greater competition in another portion, this . . . is a decision that must be made by Congress and not by private forces or by the courts.”208United States v. Topco Assocs., 405 U.S. 596, 611 (1972) (Brennan, J., concurring); see also United States v. Phila. Nat’l Bank, 374 U.S. 321, 371 (1963) (observing that an “ultimate reckoning of social or economic debits and credits” is “[a] value choice of such magnitude” as to be “beyond the ordinary limits of judicial competence, and in any event has been made for us already, by Congress”).
It is not the courts’ place to decide “which markets, and market participants, are more deserving of competition in discrete parts of the economy.”209Brief for the Am. Antitrust Inst. as Amicus Curiae in Support of Respondents at 7, NCAA v. Alston, 141 S. Ct. 2141 (2021) (No. 20-512).
Moreover, this principle seems even more potent in the healthcare context; how can courts be the ones to decide which consumers are more deserving of a competitive healthcare market?

Finally, holding the doctrinal line against religious exemptions for anticompetitive conduct is important to ensure fair and consistent treatment under the antitrust laws. For instance, what if two abortion clinics agreed that they would institute a pricing cap on the price of dilation and curettage to ensure that women in the community could access care at an affordable price? Such a restraint would constitute a per se illegal price fixing agreement, regardless of the good intentions of the clinics. Yet a religious exemption might allow some firms to get away with similar behavior, if they could prove it was religiously motivated. It might allow, for instance, two pediatric clinics that form a joint venture to justify one clinic requiring the other to cease providing childhood vaccinations to patients because of the first clinic’s religious objection to vaccines. As others have noted, “[I]t would obviously harm predictability to treat identical practices or transactions differently by reason of subjective occurrent thoughts.”210Daniel Francis, Making Sense of Monopolization, 84 Antitrust L.J. 779, 816 (2022).
Moreover, writing in a religious exemption for anticompetitive behavior would likely open the floodgates to more problematic behaviors, as “[e]very practice that makes consumer harm possible and profitable leaves a loaded gun lying around the economy that someone might later decide to pick up and use.”211Francis, supra note 115, at 266.
The creation of a religious exemption to the Sherman Act would almost certainly result in a wave of defendants using religion to justify anticompetitive behaviors. Dealing with such cases does not seem like a good use of courts’ time.

* * *

For the reasons detailed in this Part, courts should refrain from expanding (either explicitly or implicitly) antitrust doctrine to allow for a religious exemption to religiously motivated output restrictions like those considered here. Refusing to provide a religious exemption to firms engaged in anticompetitive conduct is both entirely in line with current antitrust law and also necessary to ensure fair and consistent treatment under antitrust law.

III. Applying a Religious Liberty Lens

If we have strict, rigid rules, and we still live or try to make a living like we did in the 1800s, we couldn’t compete in our businesses. . . . In order to succeed and make a living and support our family, we can’t compete if we’re out here trying to build houses with hand saws and hammers and nails. We would have no job because it would take us way too long . . . . —Al Yoder 212 DW Documentary, The Lives of the Amish in the US, at 18:21–18:34; 21:00–21:18, (YouTube, Jan. 5, 2024), https://youtu.be/B9He5DVePvk?si=cgzpXuAvgY2AiYKf (Amish carriage builder explaining why his religion permits technology in the business realm but not the home).

Religious-secular collaborations and hospital sales that impose religiously motivated restrictions at secular institutions can cause serious anticompetitive harm. Antitrust law, as a doctrinal matter, cannot and should not be read to excuse such anticompetitive restraints due to their religious overtones. But protection from antitrust liability might be found elsewhere. Indeed, there is good reason to believe that any attempt to challenge these restraints today, while solidly grounded in antitrust doctrine, may ultimately run aground in the shallows of religious liberty law. Although just fifteen years ago it was clear that corporations could not justify anticompetitive behavior on the basis of religious belief, the Supreme Court’s recent expansion of religious liberty rights213See infra Sections A–.B.
raises the possibility that religious firms may now engage in otherwise impermissible anticompetitive behavior if they can frame it in free exercise terms.214We might suspect this to be particularly true when that behavior primarily impacts access to reproductive healthcare services. See generally Elizabeth Sepper, Anti-Abortion Exceptionalism After Dobbs, 51 J.L. Med. & Ethics 612 (2023).

This Part provides a preliminary look at some of the key doctrinal issues—under both the First Amendment and the Religious Freedom Restoration Act (RFRA)—that are likely to arise in a suit challenging religiously motivated restraints, like those considered in Part II. The goal is not to provide an exhaustive analysis but to consider key questions and points of dispute. This initial analysis suggests that the plaintiffs (and therefore the government) should prevail: The Sherman Act’s prohibition of religiously motivated, anticompetitive restraints both serves a compelling interest and is appropriately tailored to achieve that interest. The doctrinal issues raised here, however, are worthy of further scholarly exploration.

A. A Comparable Secular Exemption

The First Amendment guarantees that “Congress shall make no law . . . prohibiting the free exercise [of religion].”215 U.S. Const. amend. I.
Until recently, the cornerstone of modern free exercise jurisprudence was Employment Division v. Smith,216Emp. Div., Dep’t of Hum. Res. v. Smith, 494 U.S. 872 (1990).
wherein the Supreme Court held that “the right of free exercise does not relieve an individual of the obligation to comply with a ‘valid and neutral law of general applicability on the ground that the law proscribes (or prescribes) conduct that his religion prescribes (or proscribes).’ 217Id. at 879 (quoting United States v. Lee, 455 U.S. 252, 263 n.3 (1982)).
However, although Smith has not been officially overruled, recent Supreme Court decisions have greatly weakened it, such that the existence of any comparable secular exemption to a law or regulation triggers strict scrutiny.218Tandon v. Newsom, 141 S. Ct. 1294, 1296 (2021) (“[G]overnment regulations are not neutral and generally applicable, and therefore trigger strict scrutiny under the Free Exercise Clause, whenever they treat any comparable secular activity more favorably than religious exercise.”). See generally Zalman Rothschild, Individualized Exemptions, Vaccine Mandates, and the New Free Exercise Clause, 131 Yale L.J.F. 1106 (2022).
One must therefore consider whether there are any comparable secular exemptions to the Sherman Act that would allow secular firms to engage in similar anticompetitive behavior.

At first glance, it would seem that a defendant hospital would be in a strong position to argue that there is at least one comparable secular exemption. At this moment in time, there are around thirty statutory exemptions to the Sherman Act219See ABA Section of Antitrust L. Federal Statutory Exemptions from Antitrust Law (2007).
and several judge-made doctrines that can be viewed as exemptions as well.220The filed-rate doctrine, for instance, prohibits private treble-damage actions alleging that industry rates approved by a regulator resulted from unlawful collusion. Keogh v. Chi. & Nw. Ry., 260 U.S. 156 (1922).
Among other things, antitrust law does not apply (or applies in a limited manner) to the “business of insurance,”22115 U.S.C. § 1012(b).
ocean shipping,222See Ocean Shipping Reform Act of 1998, Pub. L. No. 105-258, 112 Stat. 1902 (codified as amended in scattered sections of 46 U.S.C. app.).
exporting cartels that send products into foreign commerce,223Export Trading Company Act of 1982, Pub. L. 97-290, tit. III, § 301, 96 Stat. 1240, 1243–1247 (codified at 18 U.S.C. § 4001–4021).
international airline alliances,22449 U.S.C. §§ 41308–41309, 42111.
or professional baseball.225Fed. Baseball Club of Balt., Inc. v. Nat’l League of Pro. Baseball Clubs, 259 U.S. 200 (1922).
Under the Court’s current jurisprudence, just one of these exemptions needs to be sufficiently comparable to trigger a religious exemption.

But as scholars have noted, 226Micah Schwartzman & Richard Schragger, Slipping from Secularism 1, 6 (Univ. of Va. Sch. of L. Pub. L. & Legal Theory Rsch. Paper Series, No. 2022-75, 2022), https://papers.ssrn.com/sol3/papers.cfm?abstractid=4266290 [perma.cc/4GX8-SUGE].
whether a court finds a comparable exemption necessarily depends on how broadly or narrowly one conceives of the state’s interest. This is because whether a secular exemption is “comparable” depends on whether it undermines the government’s interest to the same, or similar, extent as a requested religious exemption. 227Tandon v. Newsom, 141 S. Ct. 1294, 1296 (2021) (“Comparability is concerned with the risks various activities pose . . . .”).
If a permitted secular exemption undermines the government’s stated goal to the same degree as a prohibited religious exemption, the activities are comparable.228Id.
Therefore, how the parties—and ultimately a court—defines the government’s interest under the Sherman Act will determine if a religious exemption is due.

A defendant seeking an antitrust exemption for religious hospitals (and their secular partners) will likely argue that the government’s interest should be conceptualized broadly: protecting competition writ large. If the government’s interest is conceptualized as protecting competition, then Congress’s exemptions for certain industries or activities can evince that the government’s interest in protecting competition isn’t absolute. And if some industries or activities are exempted, so too should anticompetitive behavior motivated by religious belief. Thus, if agreements relating to anti-hog-cholera serum and hog-cholera virus are exempt from the antitrust laws, and they are,229Act of Aug. 24, 1935, ch. 641, §  57, 49 Stat. 750, 781 (codified at 7 U.S.C. § 852).
then so too should the restraints in Part II. Or, similarly, a party might argue that because the medical residency matching program (which arguably constitutes an output- and price-fixing agreement within the physician labor market) has been immunized from antitrust liability,230See 15 U.S.C. § 37b.
so too should religiously motivated agreements to limit output or not compete.231The Supreme Court has recognized that businesses have a First Amendment right to engage in political lobbying even when they lobby for legislative action that is intended to harm their competitors or the competitive process. See E. R.R. Presidents Conf. v. Noerr Motor Freight, Inc., 365 U.S. 127, 135 (1961) (“We accept . . . that no violation of the Act can be predicated upon mere attempts to influence the passage or enforcement of laws.”); United Mine Workers v. Pennington, 381 U.S. 657, 670 (1965) (“Joint efforts to influence public officials do not violate the antitrust laws even though intended to eliminate competition.”). But this line of cases does not represent an exemption to the Sherman Act; it merely lays out the scope of the Act. As the Eighth Circuit has explained, “it was the competitors in commerce that Senator Sherman had in mind as the concern of his bill,” not participants to the legislative process. Missouri v. Nat’l Org. for Women, 620 F.2d 1301, 1304–16 (8th Cir. 1980).

A hospital might also point to the existence of a Certificate of Public Advantage (COPA) statute, if one exists in the relevant state. COPA laws allow state agencies to approve mergers and collaborations that are traditionally considered anticompetitive if the state determines the benefits outweigh the potential harms.232See Garmon & Bhatt, supra note 202, at 466.
If the state has allowed an otherwise anticompetitive collaboration to take place in one market, the hospitals would likely use this allowance as evidence that the government’s interest in promoting competition is not absolute. In fact, the hospitals might even argue, relying on Fulton v. City of Philadelphia,233Fulton v. City of Philadelphia, 141 S. Ct. 1868 (2021).
that the very existence of the state action doctrine itself, which allows states to subvert the competitive process in pursuit of specific policy goals,234Cal. Retail Liquor Dealers Ass’n v. Midcal Aluminum, Inc., 445 U.S. 97, 105 (1980).
demands a religious exemption. In Fulton, the Court made clear that, when the government retains any discretion to grant exemptions from a general rule, it must exempt religious objectors unless it can satisfy the strict scrutiny test.235Fulton, 141 S. Ct. at 1879.
Therefore, defendants might argue that, if the state can absolve potentially anticompetitive conduct for a secular reason, then it must do the same for religious reasons.

Those who oppose a religious exemption will, on the other hand, seek to show that such a broad conceptualization of the government’s interest is inaccurate. Plaintiffs will likely argue that framing the government’s interest as simply “protecting competition writ large” is inherently counterintuitive in the antitrust context, given that the first step in any Section 1 case is to define the relevant market—the economic sphere that measures and assesses anticompetitive conduct.236See, e.g., Ohio v. Am. Express Co., 138 S. Ct. 2274, 2285 (2018) (noting that the first step in determining whether a restraint is anticompetitive is to define the relevant market).
Defining the relevant market is a necessary precursor to determining participants’ market share, the relevant competitors in the market, and, importantly, whether the challenged conduct is anticompetitive. What is anticompetitive in one market might not be so in another.

For example, the restraints discussed in Part II suggest that the government’s interest needs to be framed in relation to the healthcare market. And plaintiffs would likely argue that the relevant market is even narrower: the market(s) for reproductive healthcare. By narrowing the focus in this way, plaintiffs can knock out most of the statutory and doctrinal exemptions that exist. The relevant question would then become: Are there any exemptions that, to an extent similar to the requested religious exemptions, undermine the government’s interest in promoting competition in these specific markets?237Note what that requested religious exemption would be: the ability to dictate the market actions of another, independent firm. See supra Part I.

Plaintiffs would, of course, argue that there are no comparable statutory exemptions exempting anticompetitive behavior in the reproductive healthcare market. And this is true—there are no exemptions specifically targeting the reproductive-healthcare markets. Moreover, they would likely argue that the state action doctrine—and therefore COPA statutes—does not represent a comparable secular exemption. The state action doctrine exempts certain anticompetitive conduct from antitrust scrutiny when private entities act pursuant to a “clearly articulated and affirmatively expressed . . . state policy” that is “ ‘actively supervised’ by the [s]tate.”238Cal. Retail, 445 U.S. at 105 (quoting City of Lafayette v. La. Power & Light Co., 435 U.S. 389, 410 (1978)).
It does not provide immunity to private actors engaging in anticompetitive behavior on their own initiative,239N.C. State Bd. of Dental Exam’rs v. FTC, 574 U.S. 494, 505 (2015) (explaining that the state action doctrine does not allow “active market participants . . . to regulate their own markets free from antitrust accountability”).
as is the case with the restraints detailed in Part II.240Whether a state must provide a COPA certificate to a religious-secular collaboration if it asks for one is a separate question, then, from whether private hospitals can enter into anticompetitive agreements with impunity simply because they might also have religious motivations.

Further, plaintiffs might argue, as scholars have, 241Schwartzman & Schragger, supra note 226, at 8.
the government can have multiple interests. While the overarching purpose of the Sherman Act (and antitrust laws in general) is to protect and promote competition within our national economy, the Act actually works to advance a multitude of more specific government interests within each of the individual markets that make up the larger economy.242Indeed, one might argue that the Sherman Act provides the government with a mechanism—protecting competition—for advancing many different compelling interests that are effectuated (at least in part) through market competition.
The government, for instance, does not seek to protect competition in the healthcare market simply for the sake of protecting competition; it does so because it believes that, by protecting the competitive process within the healthcare market, it will ensure its citizens can purchase innovative, affordable, and quality healthcare services. As such, the government’s decision to provide an exemption in any particular market based on government interests specific to that market does not mean that it has necessarily undermined its interest in protecting competition in other markets.

B. Substantial Burden

RFRA provides that the “[g]overnment shall not substantially burden a person’s exercise of religion even if the burden results from a rule of general applicability.”24342 U.S.C. § 2000bb-1.
A court considering a religious liberty defense to the restraints described in Part II will therefore need to consider whether Section 1’s prohibition on anticompetitive restraints substantially burdens Catholic hospitals’ exercise of religion.

Given the Supreme Court’s decision in Burwell v. Hobby Lobby Stores, Inc.,244Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682 (2014).
a Catholic hospital will arguably be on strong footing in asserting that Section 1’s anticompetitive-restraint prohibition substantially burdens their free exercise rights. In Hobby Lobby, the plaintiffs argued that the Affordable Care Act’s contraceptive mandate substantially burdened their exercise of religion because it forced them to be complicit in behavior that they viewed as ending an innocent life.245Id. at 691. Both Hobby Lobby and the restraints considered here involve what Reva Siegel and Douglas NeJaime have termed “complicity-based conscience claims”—claims that focus on the conduct of others outside the faith community. Douglas NeJaime & Reva B. Siegel, Conscience Wars: Complicity-Based Conscience Claims in Religion and Politics, 124 Yale L.J. 2516, 2520 (2015).
In their eyes, certain forms of contraception are abortifacients, and to provide their employees with insurance coverage for such medications would be tantamount to funding abortion.246Hobby Lobby, 573 U.S. at 700–02.
While the government argued that the link between providing coverage and the potential ending of human life was too attenuated to substantially burden the owners’ religious exercise, the Court rejected this argument, noting that it was outside the Court’s jurisdiction to say that the plaintiffs’ beliefs “are mistaken or insubstantial.”247Id. at 725.
Because the owners were forced (in their eyes) to choose between funding their employees’ use of immoral services or dropping their employee insurance plans altogether and paying a penalty,248Id. at 726.
the mandate constituted a substantial burden on their free exercise.249Id.

Here, the Catholic hospital would likely make a similar complicity-based argument. The Catholic hospital might argue, for instance, that the Sherman Act’s prohibition on output restrictions in a competitor collaboration substantially burdens its exercise of religion because the prohibition forces the Catholic hospital to choose between collaborating in a way that makes it morally complicit or not collaborating at all.250Here, I try to present the strongest case for the Catholic hospital, though it’s unclear whether the Sherman Act would require morally complicit collaboration. The Act does not bar hospitals from using religious “firewalls” to keep Catholic staff, funds, and equipment from supporting prohibited services.
This, in turn, restricts the hospital’s ability to grow and might even cause it to fail. Similarly, in the business-sale context, the argument would be that selling the hospital to a buyer who may offer prohibited services makes the Catholic hospital complicit and gives rise to scandal. 251This argument is much weaker than the collaboration argument. If the Catholic hospital has been sold to a new, secular owner, it is hard to see how the former owners of the hospital become complicit when the new owners begin allowing providers to provide the full range of reproductive healthcare services. Indeed, while Justice Alito’s opinion in Hobby Lobby seemed to suggest that courts could never consider how attenuated the burden on religious exercise truly is because doing so requires interrogating the good-faith beliefs of the claimants, the facts here highlight the problematic nature of such a rule. It would require that the courts simply accept, without question, that an individual’s own free exercise is burdened when they are prohibited from imposing their religion on others with whom they share no relationship.
Thus, the Sherman Act’s prohibition on noncompetes may force the Catholic hospital to choose between selling its hospital to a morally unsuitable buyer or not selling at all. Put differently, the Sherman Act imposes a substantial burden on Catholic hospitals by making the hospital choose between adherence to its faith and financial growth.252The Catholic hospital might also make an argument that is not based in complicity reasoning: The prohibition of anticompetitive restraints unreasonably burdens its free exercise because it prevents the hospital from persuading other market actors of the value of religiously informed healthcare (i.e., converting others to its faith). As the Directives explain, “collaborative arrangements [with other institutions] can provide opportunities for Catholic health care institutions to influence the healing profession through their witness to the Gospel of Jesus Christ.” U.S. Conf. of Cath. Bishops, supra note 36, at 23. But the Sherman Act does not prohibit firms or their employees from discussing their religious beliefs with competitors.

Given how deferential Hobby Lobby was to the plaintiff’s substantial burden argument, it is possible that a court would find the above arguments persuasive. But it is also possible that a court would be reluctant to find that a corporation’s free exercise rights are substantially burdened by the inability to control another market actor’s actions. In Hobby Lobby, after all, the plaintiffs did not seek to control their employees’ behavior; the company sought simply to ensure that they themselves did not subsidize behavior they believed to be immoral. In fact, one can describe Hobby Lobby as an opinion solely focused on the unilateral right of corporations, for-profit and non-profit alike, to refuse “to engage in activities to which they object on grounds of conscience.”253Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682, 716 (2014).
But the restraints considered here present a different question: Are a corporation’s free exercise rights substantially burdened when the corporation is prohibited from preventing other market actors from engaging in activities to which it objects on grounds of conscience?

Plaintiffs would of course argue that the answer is no. And to support their argument, they might try to distinguish between two important, often-conflated concepts: (1) the plaintiffs’ sincere religious belief that the coverage mandate made them complicit in immoral behavior, and (2) the plaintiffs’ belief that having to choose between that complicity and paying significant fines constituted a substantial burden. The Court’s opinion made clear that courts have no role to play in evaluating the reasonableness of a plaintiff’s belief that certain behaviors would make them complicit.254Id. at 686.
But this question is separate from whether a regulation imposes a substantial burden. A careful reading of the Court’s opinion in Hobby Lobby shows it found the coverage mandate to impose a substantial burden because it forced the plaintiffs to pay “an enormous sum of money—as much as $475 million per year in the case of Hobby Lobby—if they insist[ed] on providing insurance coverage in accordance with their religious beliefs.”255Id. at 726.

Put differently, the regulation in Hobby Lobby required Hobby Lobby’s owners to choose between suffering “substantial secular costs” for being religiously compliant and “substantial religious costs” for complying with a secular law. 256See Ira Lupu & Robert Tuttle, Symposium: Religious Questions and Saving Constructions, SCOTUSblog (Feb. 18, 2014) (emphasis added), https://www.scotusblog.com/2014/02/symposium-religious-questions-and-saving-constructions [perma.cc/N4GS-WETJ].
To distinguish the facts here from those in Hobby Lobby, then, the plaintiffs might argue that there is no similar religious-secular tradeoff. While violating Section 1 of the Sherman Act can result in treble damages, compliance with it does not necessarily impose a religious cost on a Catholic hospital. The hospital is still free to operate under Catholic doctrine and collaborate or sell only to those market actors it finds morally suitable; the Sherman Act does not require Catholic hospitals to collaborate with secular hospitals or to sell to any particular market actor. Catholic hospital employees and stakeholders are also free to advocate for expanding Catholic healthcare principles. Section 1 of the Sherman Act simply prohibits the Catholic hospital from imposing an anticompetitive restraint (e.g., its religious beliefs) on another market competitor (or a secular firm from agreeing to an anticompetitive restraint proposed by a Catholic hospital).

Notably, to conclude that such a prohibition does not constitute a substantial burden does not require a court to doubt the sincerity (or reasonableness) of a Catholic hospital’s beliefs regarding complicity. Instead, it requires a court to distinguish between accepting the Catholic hospital’s sincere belief—that it would be complicit in immoral behavior were it to voluntarily collaborate with or sell to a firm that engages (or plans to engage) in behavior prohibited by Catholic doctrine—and accepting the Catholic hospital’s argument that to be denied the ability to impose an output restriction or noncompete on another firm substantially burdens its religious exercise. More simply, it only requires a court to reject the argument that a corporation’s exercise of religion is substantially burdened when it cannot impose that religion on another corporation.

Plaintiffs might also argue that to accept the argument that Section 1 imposes a substantial burden on religious firms would provide Catholic hospitals with an unwarranted and artificial competitive advantage.257In his opinion in Hobby Lobby, Justice Alito noted that, were the owners of Hobby Lobby to eliminate health insurance from their employee benefits, “it is predictable that the compan[y] would face a competitive disadvantage in retaining and attracting skilled workers.” Hobby Lobby, 573 U.S. at 722. Yet a religious exemption that provides an unfair competitive advantage to religious firms is just as problematic, as others have noted. See Kent Greenfield, Corporations Are People Too (And They Should Act Like It) 100 (2018) (“[T]he regulatory exception gained by the corporation should not be so great that it gives the corporation a material advantage in the marketplace.”); William P. Marshall, Bad Statutes Make Bad Law: Burwell v Hobby Lobby, 2014 Sup. Ct. Rev. 71, 127 (“[A]ny claim put forth by a for-profit entity that would allow it to gain an economic advantage over its competitors should face judicial resistance because of the obvious unfairness to competitors and because of the likelihood that it would encourage strategic claims to exploit RFRA’s protections.”).
Catholic hospitals arguably face a (self-imposed) competitive disadvantage in the market: Their ability to collaborate with or to sell to particular market actors is constrained by religious doctrine. In contrast, no such constraint impedes a secular hospital’s evaluation of a potential collaborator or buyer, meaning it may benefit from more financial growth opportunities. But these two types of firms are (currently) on even footing under the Sherman Act: Neither can justify imposing anticompetitive agreements on the market on the basis of social, noneconomic goals. Buying into the Catholic hospital’s substantial burden analysis, however, upends that even footing and provides Catholic hospitals with immunity for anticompetitive behavior that is not available to secular firms.258To do so would result in a form of what scholars have termed “structural preferentialism,” a regime in which religious firms are given special treatment not otherwise available to secular firms. See Richard Schragger, Micah Schwartzman & Nelson Tebbe, Reestablishing Religion, 92 U. Chi. L. Rev. 199, 208 (2025).
And this would improperly “shift the costs of observing one’s religion to others who do not believe or practice it,” in effect imposing a tax on nonadherents.259Frederick Mark Gedicks & Rebecca G. Van Tassell, Of Burdens and Baselines: Hobby Lobby’s Puzzling Footnote 37, in The Rise of Corporate Religious Liberty 323, 334 (Micah Schwartzman, Chad Flanders & Zoë Robinson eds., 2016). Here, both consumers and providers at secular institutions pay the “tax.”
In other words, finding a substantial burden would not only be incorrect—it would also represent an unfair “redistribution” of the private market order, like that decried by the Hobby Lobby plaintiffs.260See Elizabeth Sepper, Gays in the Moralized Marketplace, 7 Ala. C.R. & C.L. L. Rev. 129, 136 (2015). This conclusion is not inconsistent with Justice Alito’s claim, in responding to the Court’s decision in United States v. Lee, 455 U.S. 252, 261 (1982), that “when followers of a particular religion choose to enter into commercial activity, the Government does not have a free hand in imposing obligations that substantially burden their exercise of religion.” Hobby Lobby, 573 U.S. at 735 n.43. Plaintiffs need not argue that there is a blanket commercial exemption to RFRA and or that one must apply the strict RFRA test to the Sherman Act.

C. Compelling Interest(s)

At the second stage of analysis under both the First Amendment261Church of the Lukumi Babalu Aye, Inc. v. City of Hialeah, 508 U.S. 520, 546 (1993).
and RFRA, 26242 U.S.C. § 2000bb-1(b)(1).
a court must consider whether the government’s refusal to provide a religious exemption to Section 1 is justified by a compelling interest. Specifically, what interest does the government have in preventing the types of restraints considered in Part II, and is that interest sufficiently weighty to override religious exercise rights?

As Elizabeth Sepper has documented, corporate challengers to the Affordable Care Act’s contraceptive mandate sought to reduce the government’s compelling interest to preserving market access.263Sepper, supra note 260, at 136–37; see also Sepper, supra note 4 at 1477–83 (showing how advocates for religious exemptions have repeatedly sought to compress the government’s compelling interest to preserving market access).
In their view, the government could not justify impinging on corporations’ (or individuals’) religious beliefs when a functioning market already permitted employees to purchase contraceptives on their own dime. And in siding with the religious objectors, several courts accepted this line of reasoning. The Tenth Circuit, for instance, reasoned that an interest in promoting sex equality could not justify the mandate because women remained “free” to purchase contraception themselves.264Hobby Lobby Stores, Inc. v. Sebelius, 723 F.3d 1114, 1144–45 (10th Cir. 2013).
The D.C. Circuit, in turn, viewed the mandate as a “subsidization of a woman’s procreative practices.”265Gilardi v. U.S. Dep’t of Health & Hum. Servs., 733 F.3d 1208, 1221 (D.C. Cir. 2013).
As articulated by Richard Epstein, the government doesn’t have a compelling interest in forcing religious firms to subsidize employees’ contraceptive use because contraceptives “are readily available in the marketplace to all comers at competitive prices.”266Epstein, supra note 6, at 52 (“Why must the state compel employers to make payments or public declarations that violate their religious beliefs when the very services at issue are freely available elsewhere?”).
Such arguments have been expanded to justify religious exemptions more broadly; Andrew Koppelman suggests, for instance, that religious exemptions to antidiscrimination laws are sensible unless “markets will not solve the problem.”267Koppelman, supra note 7, at 133.

Whether one agrees with these arguments, it should be clear that those advocating for a religious exemption to the mandate implicitly assumed religious businesses were not acting in ways that impeded market competition and, therefore, consumers’ ability to purchase contraception at competitive prices.268See Sepper, supra note 260, at 138.
Indeed, the Tenth Circuit noted specifically that religious employers opposing the mandate did not seek to “prevent employees from using their own money to purchase” contraceptives in the market.269Hobby Lobby Stores, 723 F.3d at 1144.
It should follow then that, should circumstances present where religious firms do engage in behavior that disrupts the market’s competitive functioning by reducing output and raising prices, the government does have a compelling interest in stopping such behavior. To argue otherwise would require defendants to suggest that the government does not have a compelling interest in preserving market access to goods and services. And while they might do so, it would be a hard argument to make.

By passing the Sherman Act, the Supreme Court explained, Congress “sought to establish a regime of competition as the fundamental principle governing commerce in this country.”270City of Lafayette v. La. Power & Light Co., 435 U.S. 389, 398–99 (1978) (emphasis added).
The Act is a “charter of freedom”271United States v. Socony-Vacuum Oil Co., 310 U.S. 150, 220–22 (1940).
that assumes “the unrestrained interaction of competitive forces will yield the best allocation of our economic resources, the lowest prices, the highest quality and the greatest material progress, while at the same time providing an environment conducive to the preservation of our democratic political and social institutions.”272N. Pac. Ry. Co. v. United States, 356 U.S. 1, 4 (1958) (emphasis added).
In fact, the Supreme Court has gone so far as to characterize the antitrust laws as “the Magna Carta of free enterprise. They are as important to the preservation of economic freedom and our free-enterprise system as the Bill of Rights is to the protection of our fundamental personal freedoms.”273United States v. Topco Assocs., 405 U.S. 596, 610 (1972) (referring to the Sherman Act).
In other words, it has long been accepted that the Sherman Act serves a fundamental role in protecting the nation’s economic interests.

Thus, plaintiffs would argue that the government has a compelling interest in preserving competition—and therefore market access—in the markets for reproductive healthcare. 274And they would not be the first to do so. See, e.g., Greenfield, supra note 257, at 100 (“[T]he importance of ensuring the fairness of marketplace competition should count as a compelling interest to justify not [providing a religious exemption].”).
In doing so, plaintiffs would do well to emphasize that, unlike in the contraceptive mandate cases, enforcing the Sherman Act in this context ensures that female consumers benefit from a free and competitive reproductive-healthcare marketplace—rather than from free reproductive health services. Similarly, in contrast to antidiscrimination laws, which have been portrayed as forcing religious firms to provide services they reject on religious grounds, the government does not seek to force Catholic hospitals (or even secular hospitals) to provide a particular service. Rather, the government seeks to ensure that any decision to provide or not to provide a service is made freely. That is, the goal is to provide an opportunity for the market to work, not to dictate what the market must provide.275Put differently, the goal is to “restor[e] conditions in which the competitive process is revived and any number of competitors may flourish (or not) based upon the merits of their offerings.” Massachusetts v. Microsoft Corp., 373 F.3d 1199, 1231 (D.C. Cir. 2004) (en banc).

But plaintiffs could argue also that the Sherman Act plays an important role not only in promoting economic freedom but religious freedom as well. While a Catholic hospital would logically focus on its own religious liberty rights, plaintiffs would do well to note that consumers also have a religious liberty interest in being able to pursue healthcare in accordance with their own religious beliefs (or lack thereof). And the existence of secular healthcare institutions—that is, institutions that do not limit healthcare treatments according to a particular religious doctrine—play an enormously important role in ensuring consumers can access care that accords with their own faith.276Plaintiffs might also note that, while the Sherman Act’s reach extends to all industries, the government’s interest in protecting competition in healthcare markets arguably takes on particular strength. Healthcare consumers purchase goods and services that promote good health or treat injury and illness; the inability to purchase certain healthcare services, or to purchase quality healthcare services, therefore has a tangible effect on quality of life—and can even be a matter of life and death.
Thus, it is one thing if Catholic healthcare spreads far and wide in the market through free and fair competition because the majority of consumers seek out healthcare compliant with Catholic doctrine. It is another matter entirely if that spread is in part a function of anticompetitive behavior that results in decreased options and subpar treatment for consumers at secular facilities. Plaintiffs might therefore argue that the government has a compelling interest not only in promoting a competitive healthcare market but also in ensuring consumers can access care that aligns with their religious beliefs (or lack thereof). Indeed, just as the government has an interest in preventing the acquisition of secular monopoly power through anticompetitive means, plaintiffs might argue, so too does it have an interest in preventing the acquisition of a religious monopoly in healthcare through anticompetitive means.277I am not the first to note the synergy between the Sherman Act and religious freedom. See Barak D. Richman, Religious Freedom Through Market Freedom: The Sherman Act and the Marketplace for Religion, 60 Wm. & Mary L. Rev. 1523, 1525 (2019).

To prohibit one but not the other would arguably be inconsistent with the “State’s obligation of religious neutrality.”278Masterpiece Cakeshop v. Colo. C.R. Comm’n, 138 S. Ct. 1719, 1723 (2018).
And plaintiffs might point to the Supreme Court’s opinion in Associated Press v. United States for support.279Associated Press v. United States, 326 U.S. 1 (1945).
There the Court rejected a free speech challenge to the Sherman Act, noting

a command that the government itself shall not impede the free flow of ideas does not afford non-governmental combinations a refuge if they impose restraints upon that constitutionally guaranteed freedom. . . . Freedom to publish is guaranteed by the Constitution, but freedom to combine to keep others from publishing is not.280Id. at 20.

Put simply, while the Constitution protects the free exercise of religion, plaintiffs would emphasize it is not just the Catholic hospital’s free exercise rights that are at stake here. Catholic hospitals (and other religious firms) have the right to unilaterally pursue the tenets of their faith, but that does not mean they have the freedom to combine and impose restraints on other market actors’ abilities to provide or purchase healthcare in accordance with their own beliefs. In the words of one court, “assuming that the [hospital’s] activity is a genuine expression of the right to exercise freely, there are still limits on the tactics that may be used to accomplish its ends.”281Costello Publ’g Co. v. Rotelle, 670 F.2d 1035, 1049–50 (D.C. Cir. 1981).
Here, plaintiffs can argue that the state has a compelling interest in protecting the religious liberty rights of all its citizens, not just some, and that the Sherman Act’s prohibition of anticompetitive restraints helps effectuate that goal.

D. Less Restrictive Alternative

Under both the First Amendment282Church of the Lukumi Babalu Aye, Inc. v. City of Hialeah, 508 U.S. 520, 546 (1993).
and RFRA,28342 U.S.C. § 2000bb-1(b)(2).
even a law or regulation justified by a compelling interest must not sweep too broadly and thereby restrict individuals’ (or corporations’) free exercise rights unnecessarily. If the government could achieve its goals through less burdensome means, it must do so. So, the question becomes, is there a way for the government to protect market competition while allowing restraints like those considered in Part II?

If one accepts that the government has a compelling interest in protecting market competition, the answer seems to be no. The key antitrust concern with respect to the restraints described in Part II is that a market actor (the secular hospital or the new, secular owner of a hospital) is unable to respond independently to market demand for reproductive healthcare because it has agreed to provide only the services that a Catholic hospital would be willing to provide. Such agreements are prohibited because their very existence distorts the competitive process by “depriv[ing] the marketplace of the independent centers of decisionmaking that competition assumes and demands.”284Copperweld Corp. v. Indep. Tube Corp., 467 U.S. 752, 769 (1984); accord Am. Needle, Inc. v. NFL, 560 U.S. 183, 190 (2010); see also Tony & Susan Alamo Found. v. Sec’y of Labor, 471 U.S. 290, 302 (8th Cir. 1985) (observing that an exemption to the Fair Labor Standards Act would enable employers to use their superior bargaining power to coerce employee waivers and would likely depress the wages of all employees in the relevant labor market).
Thus, because the restraints themselves are problematic, it would seem that the government’s interest in protecting competition can be achieved only by prohibiting the restraints entirely, that is, by prohibiting the output restriction or agreement not to compete. Either the secular healthcare provider is free to respond independently to market demand, or it is not.285See Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682, 734 (2014) (“[T]he fundamental point would be that there simply is no less restrictive alternative to the categorical requirement to pay taxes.”).

Importantly, however, this does not mean that there might never be a less restrictive alternative available under the Sherman Act—or other antitrust laws. Antitrust law does not seek to dictate a particular market outcome or any particular level of competition; instead, it seeks to ensure that competitive market conditions are not impeded by illegal conduct. As such, relevant agencies have sought to appropriately thread the needle between protecting competition and preventing anticompetitive behavior when crafting remedies for Sherman Act Section 2 and Clayton Act Section 7 violations.286Edward Cavanagh, Antitrust Remedies Revisited, 84 Or. L. Rev. 147, 188–92 (2005).

For instance, rather than prohibit a proposed merger entirely, the agencies might instead accept certain structural remedies that would adequately protect market competition.287For example, on May 28, 2025, the FTC mandated that Synopsys, Inc. and Ansys, Inc. divest assets to mitigate antitrust issues arising from their merger. FTC, Statement of Chairman Andrew N. Ferguson 1 (2025), https://www.ftc.gov/system/files/ftc_gov/pdf/synopsys-ansys-ferguson-statementjoined-by-holyoak-meador.pdf [perma.cc/3DME-ZS2N].
And, as noted earlier, creative structural remedies have been employed in the context of religious-secular hospital mergers, remedies that have allowed for services to continue while simultaneously respecting a Catholic hospital’s need to distance itself from allegedly immoral procedures.288Durand, supra note 17, at 2623–24.
One might therefore argue that the government’s decision to completely block a religious-secular hospital merger, rather than allow some sort of structural remedy to preserve care, would fail both the narrow tailoring and least restrictive alternative tests of the First Amendment and RFRA.

Whether structural or behavioral remedies could allow for a compromise between the government’s interest in protecting the competitive process and a religious firm’s desire to engage in conduct that runs afoul of the antitrust laws, then, depends on the type of conduct at issue. Section 1’s flat prohibition against anticompetitive restraints suggests there is no remedy other than removing the restraint; in certain monopolization and merger cases, however, there might be more room for compromise.

* * *

Currently, there is no religious exemption to the Sherman Act’s prohibition against anticompetitive restraints. Yet, because of the prevailing winds of religious liberty law, religious firms that find themselves facing an antitrust challenge to the restraints considered here will certainly be incentivized to raise a religious liberty defense. My analysis suggests that a religious liberty defense should be rejected. Even if a court finds that defendants have the better argument on the first prong of either First Amendment or RFRA analyses (an outcome that is by no means certain), the Sherman Act’s prohibition of religiously motivated, anticompetitive restraints both serves a compelling interest and is appropriately tailored to achieve that interest. In other words, there are market limits to free exercise rights.

IV. Bringing a Case: Some Practical Considerations

I have argued that Catholic and secular hospitals have routinely entered into agreements that violate Section 1 of the Sherman Act, thereby harming competition and reducing community access to reproductive healthcare. Plaintiffs may therefore want to bring suit under Section 1 of the Sherman Act challenging the types of restraints analyzed in Part II. The removal of these restraints will allow the market to operate according to the natural give-and-take of market forces, thereby incentivizing hospitals (secular and religious alike) to provide the full range of reproductive healthcare services.289This does not mean that the secular hospital must begin providing care. The hospital (and its providers) simply regains the power to determine output consistent with its own needs for profit and understanding of what constitutes the most appropriate form of care for a particular patient.
Given the unique nature of these agreements, I make two suggestions for potential plaintiffs to consider.

First, any plaintiff that files suit should file suit only against the secular hospital. Doing so will allow the plaintiff to make clear that the goal of an antitrust challenge is not to force the Catholic hospital290Or individual providers at either hospital.
to provide healthcare services to which it is morally opposed, but to require the secular hospital to begin allowing its providers to provide healthcare in accordance with patient need and their best medical (and moral) judgment. It also helps highlight the fact that the secular hospital has no religious liberty defense of its own and is restricting its doctors’ ability to provide appropriate care to patients for profit-maximizing reasons.

Second, while the antitrust laws allow for private and public enforcement, doctrinal standing concerns suggest that state attorneys general are best suited to bring suit, at least if damages are sought as part of the remedy. This is because one of the key harms imposed by the agreements in Part II is the inability to purchase healthcare. This results in a form of deadweight loss, a concept that has not been adequately incorporated into consumer antitrust doctrine.291Leslie, supra note 125, at 522.
This is likely due, at least in part, to the difficulty in estimating individual-level deadweight loss damages.292Id. at 557.
But, as others have argued, state attorneys general have the ability to bring parens patriae suits to recover aggregate deadweight loss.293Id. at 559.

A. The Secular Hospital as Sole Defendant

Antitrust conspirators face joint and several liability.294Tex. Indus., Inc., v. Radcliff Materials, Inc., 451 U.S. 630, 646 (1981).
I suggest, however, that potential plaintiffs sue the secular hospital and only the secular hospital. I do so for both practical and strategic reasons.

As a starting point, the first-order goal of any lawsuit challenging the above restraints is to increase access to care by removing the anticompetitive restraint. In the competitor-collaboration scenario, the secular hospital has agreed to cease providing certain services to the community that it would otherwise provide. Meanwhile in the secular buyer scenario, the buyer has agreed never to provide those services for the duration of the contract, regardless of its own desires and community demand. Both lead to an artificial suppression of healthcare in the community. The first goal of any lawsuit, then, is injunctive relief requiring the secular hospital to allow its providers to provide the full range of medical care. It is not the goal, in contrast, to require the Catholic hospital (or even individual providers at either hospital) to provide care in violation of sincerely held religious beliefs. As such, injunctive relief can only target the secular hospital.

But even if a plaintiff were to sue for damages as well, strategic considerations suggest that it should, again, sue only the secular hospital. Doing so helps emphasize that the goal of the lawsuit is to end the anticompetitive restraint, not to attack religious healthcare per se. After all, the secular hospital has no religious liberty defense in support of its actions. Its only hope is to show why its agreement to limit output does not violate the Sherman Act. This, as I demonstrated in Part II, is something it cannot do.

It is possible, of course, that the secular hospital might move to join the Catholic hospital under Rule 19 of the Federal Rules of Civil Procedure, which states that a required party must be joined in an action if feasible.295 Fed. R. Civ. P. 19(a)(1)(B)(i).
Similarly, the Catholic hospital might move to intervene, arguing that the case raises important issues about its ability to operate in the market as a religious healthcare provider. 296See Fed. R. Civ. P. 24(a)(2).
However, either action poses some risks for the hospitals. Doing so would highlight, first, that the secular hospital has no religious reason for its behavior and has agreed to cease providing standard and popular services to the community for profit-maximizing reasons, and, second, that the Catholic hospital is trying to deny access to care not just at its own facilities but others as well. The public will likely find neither fact particularly palatable. In fact, history suggests that some religious-secular collaborations and proposed mergers have fallen apart following community outcry when the real-world effects (i.e., denial of care) became public.297For instance, an agreement linking the nonsectarian Sierra Vista Medical Center with the Catholic Carondelet Health System was dissolved in 2011, after it became known that administrators refused to allow a doctor to provide an emergency abortion to a patient suffering a miscarriage. MergerWatch 2013, supra note 83, at 14; see also Stephanie Innes, Tucson Health: Carondelet and Sierra Vista Medical Center Dissolve Agreement, Ariz. Daily Star (Mar. 30, 2011), https://tucson.com/news/blogs/health/tucson-health-carondelet-and-sierra-vista-medical-center-dissolve-agreement/article_e98acc9e-5a52-11e0-9779-001cc4c03286.html [perma.cc/DCE2-TWHT].

In sum, plaintiffs should sue the secular hospital because of the mismatch between which hospital is the target for injunctive relief (the secular hospital) and which hospital is motivated by religious belief (the Catholic hospital). Suing only the secular hospital highlights the disjunction within this mismatch and will make for a cleaner argument before the court, thereby decreasing the chances of a court improperly concluding that the plaintiff seeks to force the Catholic hospital to provide morally contested services. Moreover, by focusing on just the secular hospital, the plaintiff can work to craft a narrative that is less about Catholic healthcare per se and more about the secular hospital’s willingness to cease or refrain from providing necessary healthcare to community members for profit-maximizing, rather than faith-based, reasons.

B. The State as Plaintiff

From an access perspective, the most important relief to be gained by challenging the restraints described in Part II is injunctive relief. Such relief would allow providers at the secular hospital to begin providing care based on patient needs and according to their best medical judgment. But the antitrust laws are designed also to provide compensation to the victims of illegal, anticompetitive behavior. Indeed, private plaintiffs are highly incentivized to bring suit, as the Clayton Act provides treble damages plus attorneys’ fees for anyone injured by an antitrust violation.29815 U.S.C. § 15(a).
In doing so, the Act creates a “crucial deterrent to potential violators.”299Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, Inc., 473 U.S. 614, 635 (1985).
But here, a claim for damages presents a few challenges, primarily because of the particular intersection between antitrust standing and the estimations of damages. In this section, I will contend that doctrinal standing issues suggest that state enforcers are best suited to bring a case for damages.

Let us begin with antitrust standing. Because the harms that flow from an anticompetitive violation are theoretically infinite—thus creating infinite potential plaintiffs—the courts have developed antitrust standing as a prudential doctrine to limit the number of plaintiffs who can bring a case.300See Antonin Scalia, The Doctrine of Standing as an Essential Element of the Separation of Powers, 17 Suffolk U. L. Rev. 881, 885 (1983); C. Douglas Floyd, Antitrust Victims Without Antitrust Remedies: The Narrowing of Standing in Private Antitrust Actions, 82 Minn. L. Rev. 1, 26 (1997).
A private antitrust plaintiff’s standing therefore turns on the following: “(1) the nature of the plaintiff’s alleged injury; that is, whether it was the type the antitrust laws were intended to forestall; (2) the directness of the injury; (3) the speculative measure of the harm; (4) the risk of duplicative recovery; and (5) the complexity in apportioning damages.”301Amarel v. Connell, 102 F.3d 1494, 1507 (9th Cir. 1996) (citing Associated Gen. Contractors of Cal., Inc. v. Cal. State Council of Carpenters, 459 U.S. 519, 535 (1983)).
While prongs (1)–(2)302The paradigmatic antitrust injury, as the Seventh Circuit has explained, is “injury from higher prices or lower output, the principal vices proscribed by the antitrust laws.” Nelson v. Monroe Reg’l Med. Ctr., 925 F.2d 1555, 1564 (7th Cir. 1991) (quoting Ball Mem’l Hosp., Inc. v. Mut. Hosp. Ins., Inc., 784 F.2d 1325, 1334 (7th Cir. 1986)). As noted in Part II, both types of injury are present here. Similarly, the harms flow directly from the anticompetitive agreement to consumers seeking reproductive healthcare in the market.
and (4)–(5)303Plaintiffs suffer only one of two types of harm: Either they are denied the ability to purchase healthcare, or they purchase care at an overcharge. Because a potential plaintiff falls into one but not both groups, there is no chance of duplicative recovery and no inherent difficulty in apportioning damages among plaintiffs.
pose no challenges in the scenarios outlined in Part II, prong (3) is a different matter.

To understand why, we need to consider how damages would be calculated in the scenarios above. Antitrust damages are typically calculated by comparing what the plaintiff’s financial results would have been in a “but for” world (i.e., one in which the antitrust violation did not occur) with the plaintiff’s financial results in the actual world.304Leslie, supra note 125, at 529–30.
For instance, in the context of a price-fixing scheme, a consumer plaintiff’s damages would generally be the difference between the price the plaintiff actually paid and the price the plaintiff would have paid absent the existence of the price-fixing scheme.305See, e.g., Mike Scarcella, US Jury Awards .7 Mln to Kraft, Other Producers in Egg Price-Fixing Case, Reuters (Dec. 1, 2023), https://www.reuters.com/legal/litigation/us-jury-awards-177-mln-kraft-other-producers-egg-price-fixing-case-2023-12-01 [perma.cc/SWA2-4SU7].
Yet the typical antitrust damages scenario does not apply to the facts above—consumers are not harmed because they paid an overcharge to the secular or Catholic hospital; they were harmed because they were either (1) denied the ability to purchase care or (2) paid an overcharge to an alternate provider in the market—that is, one that was not party to the anticompetitive agreement.

It may be helpful here to add some numbers to the discussion. Say the competitive price (the price that would exist absent the anticompetitive restraint) for a tubal ligation in either scenario considered in Part II is $4,000, while the supracompetitive price (the price an alternate provider in the market can charge in light of the secular hospital’s restraint on output) ranges from $4,500 to $7,000, depending on how many additional providers are in the market. And let’s say that we have two hypothetical consumers, one who is willing to pay $5,000 for a tubal ligation and one who is willing to pay $6,000.

Under competitive conditions, one hypothetical consumer receives a surplus of $1,000—the difference between her reservation price and the actual market price—while the other receives a surplus of $2,000. But under anticompetitive conditions—that is, when the Catholic and secular hospital (or buyer) enter into their agreement—each consumer either pays an overcharge at an alternate hospital or is unable to purchase care at all. As Table 1 demonstrates, which harm occurs will depend upon both the individual consumer’s reservation price and how many other competitors exist in the market, if any.

We see, for instance, that the consumer with a higher reservation price of $6,000 can access care (albeit at an overcharge) under more market scenarios than the consumer with a lower reservation price. This means that higher income individuals (or individuals with more comprehensive insurance coverage) are more likely than lower income individuals to secure treatment in the face of the anticompetitive restraints analyzed here.306One physician detailed the disparate effects based on income following her hospital’s decision to stop providing tubal ligations:

When they first stopped doing it I thought it was terrible because our hospital is the main maternity hospital and our patients . . . tend to be the lower socioeconomic patients. . . . So you had a situation where if you had insurance, had a job or had money, you could go over across the street and get your tubal done. But if you were, you know, getting Medicaid or if you had [state public insurance], then you didn’t have access to that, and I thought it was a terrible double standard.

Stulberg et al., supra note 12, at 424 (alteration in original).
But in two-hospital markets, consumers are unable to access care regardless of income level or insurance coverage. Thus, potential plaintiffs fall into two buckets: Either they suffer an overcharge receiving care at an alternate provider not party to the agreement, or they are unable purchase a particular reproductive healthcare service altogether.

This is problematic from a standing perspective for two reasons. The first reason is that it is impossible—at least without engaging in speculation—to calculate the individual damages suffered by those consumers who are denied the ability to purchase care. In Table 1, each consumer’s reservation price is simply assumed, but in real life, of course, that number would need to be subject to reasonable proof. This poses a major problem in the litigation context, as there must be a reasonable basis for assumptions employed in the plaintiff’s damages model.307 ABA Section of Antitrust L., Sample Jury Instructions in Civil Antitrust Cases F-8 (1999).
The second reason is that the plaintiffs who are forced to pay an overcharge at an alternate provider in the market are what we call “umbrella victims.” Umbrella victims are consumers who purchase a supracompetitive-priced product not from a member of a cartel but from another firm in the market that has raised its prices under the “umbrella” of the higher price charged by the cartel members.308See Ahmed Alfaris, Antitrust Standing for Umbrella Purchasers, 58 U.S.F. L. Rev. 1, 1–2 (2023). That is, while many antitrust conspiracies are incomplete (i.e., they do not include every competing firm in the market), their market effects often allow or lead non-conspiring firms to also raise their prices to a supracompetitive level. Yet because these firms do not commit an antitrust violation in doing so, consumers cannot sue them for the overcharge. Instead, such consumers must sue the cartel members under an umbrella pricing theory.
Courts are currently divided on whether or not umbrella victims have standing to bring an antitrust claim,309Compare U.S. Gypsum Co. v. Ind. Gas Co., 350 F.3d 623, 627 (7th Cir. 2003), and In re Beef Indus. Antitrust Litig., 600 F.2d 1148, 1166 n.24 (5th Cir. 1979), with Mid-West Paper Prods. Co. v. Cont’l Grp., Inc., 596 F.2d 573, 580–87 (3d Cir. 1979).
with those denying standing generally doing so due to concerns about potentially speculative and duplicative damages recovery.310See, e.g., Mid-West Paper, 596 F.2d at 585, 583 (finding that accounting for umbrella damages would allow for duplicative recovery and require complicated and fruitless economic analysis of causation and effect); In re Coordinated Pretrial Proc. in Petroleum Prods. Antitrust Litig., 691 F.2d 1335, 1340–41 (9th Cir. 1982) (concluding proving an overcharge would have been a speculative endeavor and allow for duplicative recovery).

Neither of these standing problems are insurmountable, however. Consider first the damages incurred by the denial of care (i.e., the deadweight loss that occurs when socially beneficial transactions do not take place). While it is very difficult to calculate an individual-level measure of harm for consumers who are denied care, it is not as difficult to calculate an aggregate measure of the harm, as Christopher Leslie has previously argued:311Leslie, supra note 125, at 562.
“Although deadweight loss cannot be calculated with pinpoint accuracy, reasonable estimates are possible. And that is all that the standard for antitrust damages requires.”312Id. at 545.
And while it would be difficult and perhaps ill-advised to allow individual consumers to sue for aggregate deadweight loss,313Id. at 558–59.
there is no reason the state could not do so. State attorneys general have the authority to pursue antitrust claims on behalf of natural persons in their states,31415 U.S.C. § 15c.
and they have done so in a broad range of consumer suits.315See Susan Beth Farmer, More Lessons from the Laboratories: Cy Pres Distributions in Parens Patriae Antitrust Actions Brought by State Attorneys General, 68 Fordham L. Rev. 361, 362–64 (1999).
Moreover, the federal parens patriae statute specifically provides that “damages may be proved and assessed in the aggregate . . . without the necessity of separately proving the individual claim of, or amount of damages to, persons on whose behalf the suit was brought.”31615 U.S.C. § 15d.
The damages secured in a parens patriae suit could then be distributed among consumers who can demonstrate that they sought and were denied care at the secular hospital or funneled to the state’s family planning programs through a cy pres distribution, among other possibilities.317Leslie, supra note 125, at 564. The damages secured in a parens patriae suit shall “(1) be distributed in such manner as the district court in its discretion may authorize; or (2) be deemed a civil penalty by the court and deposited with the State as general revenues.” 15 U.S.C. § 15e.

Now let us consider umbrella victims. A closer examination shows that there is no problem when it comes to standing because the concerns that have motivated some courts’ denial of standing—the difficulty in estimating damages and the threat of duplicative recovery—are not present under the types of restraints considered in Part II. First, calculating the overcharge incurred by consumers who sought care at an alternative provider poses no greater difficulty or speculation than calculating an overcharge in the typical antitrust case. The agreements in Part II require the secular hospital to decrease its output (or refrain from increasing its output) artificially, which will in turn provide the other providers in the market with more patients and, therefore, greater market share. Plaintiffs can present expert economic evidence, supported by patient inflow data and payor claims data, demonstrating the decrease in output and its foreseeable impact on other competitors in the market. There may even be evidence that the secular hospital’s cessation of services positively impacted competitor hospitals’ bargaining positions with insurance networks seeking to ensure that their members can access the full spectrum of reproductive care.

Second, there is no possibility of duplicative recovery as there are only two types of harm imposed—overpaying or an inability to purchase—and consumers can fall into only one of those two buckets. That contrasts a more typical antitrust case, in which there are direct purchasers who are considered the most appropriate plaintiff. There are no direct purchasers in the scenarios outlined above, only those who are denied care and those forced to purchase it elsewhere at a supracompetitive price. The sum of the overcharge damages and the aggregate deadweight loss is therefore equal to the total harm imposed by the agreement.

That damages concerns have led some courts to deny that umbrella standing does not apply to the scenarios analyzed here suggests the umbrella victims, if not the “deadweight loss” victims, could successfully bring individual suits or a class action suit. But such a suit could account only for a portion of the harm imposed by the hospitals’ anticompetitive agreement—consumers who were denied the ability to purchase care would be left out. As such, I suggest that the most efficient approach is for the state to bring suit on behalf of both sets of consumers.

Conclusion

In 2010, “historically secular Sierra Vista Regional Health Center in southeastern Arizona began a trial two-year affiliation with the Catholic Carondelet Health Network, a member of the Ascension Health system.”318 MergerWatch 2013, supra note 83, at 14.
The affiliation was expected to culminate in a merger between the two entities. “As a condition of the affiliation, Sierra Vista, the sole community provider of acute care in a rural three-county region, was required to follow the Directives.”319Id.
Shortly after the trial affiliation began, a woman experiencing a miscarriage at fifteen weeks presented at the hospital. The patient had been carrying twins and had already miscarried one of the twins at home.320Id.
When she arrived at the hospital, she was stable, “[b]ut the umbilical cord from the first fetus was coming out of her vagina, while the second fetus was still in her uterus.”321Jonathan Cohn, Unholy Alliance, New Republic (Feb. 22, 2012), https://newrepublic.com/article/100960/catholic-church-hospital-health-care-contraception [perma.cc/68HN-XK4N].
The doctor who examined her recommended that she receive an abortion given the low chance of a successful pregnancy and the high risks of severe hemorrhaging and infection.322 MergerWatch 2013, supra note 83, at 14.
The patient and her husband agreed with this course of treatment, and the physician prepared to complete the miscarriage.323Id.
But the remaining fetus had a heartbeat, meaning that abortion was not permitted under the Directives—at least not until an abortion would be necessary to preserve the mother’s life. This fact led a hospital administrator to intervene and order the physician to transfer the patient to avoid violating the Directives.324Id.
According to the physician’s deposition, the administrator did not inquire as to the possible risks or complications of denying treatment, whether the patient could possibly continue the pregnancy, where the patient would be transferred, or how long it might take her to receive treatment.325Affidavit of Robert Holder ¶¶ 9–29 (Dec. 10, 2010), https://www.washingtonpost.com/wp-srv/health/documents/abortion/holder-affidavit.pdf [perma.cc/2JF5-LXPP].
The doctor was forced to return to the patient and her husband and inform them that he could not provide the agreed-upon treatment. Instead of receiving care at Sierra Vista, the patient was sent by ambulance to another hospital eighty miles away.326Id. at 3.
This ambulance trip put her at risk of hemorrhaging and sepsis, although her condition luckily did not worsen, and she received the care she needed.327Cohn, supra note 321.

This denial of care has been frequently highlighted as an example of the dangers religious healthcare restrictions pose to patients.328See, e.g., id.; MergerWatch 2013, supra note 83, at 14; Stephanie Mencimer, Do Bishops Run Your Hospital?, Mother Jones (Nov. 2013), https://www.motherjones.com/politics/2013/10/catholic-hospitals-bishops-contraception-abortion-health-care [perma.cc/6FNR-9SJL].
But while it seems everyone recognized the inherent wrongness of the situation—a patient being denied care that she and her provider felt was both medically and morally appropriate, and in a secular hospital no less—no observers appear to have recognized that this story had antitrust implications. As this Article has demonstrated, this trial affiliation contained an illegal output restriction. According to the public reporting, Sierra Vista and Carondelet Health, although in the process of merging, had not yet done so. Instead, they were still operating as separate, competing market actors.329Arizona’s Carondelet Health and Sierra Vista Regional Sign Agreement to Share Resources, Becker’s Hosp. Rev. (Mar. 17, 2010), https://www.beckershospitalreview.com/uncategorized/arizonas-carondelet-health-and-sierra-vista-regional-sign-agreement-to-share-resources [perma.cc/FV8V-ABJ4].
Yet, due to the agreement, Sierra Vista could not act as an independent economic actor and provide treatment to patients unless the Carondelet Health Network was willing to do so as well.

While the board of Sierra Vista Regional Medical Center voted to discontinue its affiliation with the Carondelet Health Network shortly after this incident,330 MergerWatch 2013, supra note 83, at 14.
there are still many secular facilities operating under religious restrictions as a matter of contract. For those who believe in a free and open marketplace, one that allows consumers to purchase and providers to provide care in accordance with their own religious beliefs, such contractual arrangements are deeply problematic. Our nation’s antitrust laws, however, offer a viable tool for combatting such exclusionary practices and ensuring that all Americans can access the care they need and deserve.
