Complexity of transnational sources

Abstract

The title assigned to the IC session on Comparative Law and Unifi cation of laws (Droit comparé et unifi-cation du droit) at fi rst seemed rather enigmatic, a very broad topic, with great potential for development in a variety of directions, and suggesting many different lines of research. I had been informed that the reports to be collected by me concerned the “ Complexity of Transnational Sources/Complexité des sources transnationales:” without an explanatory subtitle this could mean several different things and I had to make up my mind about the approach to take in such a broad fi eld of investigation. I needed to defi ne a line to propose to our reporters: the problem crosses borders between the competences of different disciplines such as Confl ict of Laws/Private International Law (including procedural issues such as enforcement of foreign judgmen s), International Law (treaty law), European Union law, Uniformation of the Law and Private Law, to name but a few.
