Required Joinder of Claims

This comparative study is confined to the situation of one claimant against one claimee. The principles which will be considered seem to be rather well settled both in the American and the German law. The fact, however, that besides many a common result we shall find fundamental differences in the pertinent basic concepts of the American and German systems makes the discussion worthwhile. It may, at least, promote a reconsideration of the propriety of those concepts.
