For many years, I have begun my courses in comparative law by explaining to students that, because of its subject matter, comparative law is different from any other discipline taught in law schools. It does not deal with a body of law as, for example, civil procedure or labor law. Rather, it is a method, or a variety of methods, used to compare different bodies of law. In this perspective, it is not difficult to see the difference between comparative law and international law or between comparative law and foreign law. Indeed, international law itself can be studied comparatively such as in much of the work devoted to comparative private international law that has been produced in the U.S.-immigrant tradition of Comparative Law, from Ehrenzweig to Fritz Juenger. But can comparative law be studied comparatively? Is there such a thing as "comparative-comparative law"?
