Hathaway: A Comparative Foreign Relations Law Agenda: Opportunities and Challenges

Oona A. Hathaway (Yale Univ. - Law) has posted A Comparative Foreign Relations Law Agenda: Opportunities and Challenges. Here's the abstract:

International law is generally understood to be made up of the rules that states accept as binding in their relations with one another. But international law is the product not only of a political and legal process that takes place between states — as this common understanding implies — but also of processes that take place within them. And yet to date there has been remarkably little cross-national work examining the role of domestic politics and law in the creation of treaties and other international law. Part of the reason for this gap is the difficulty of conducting cross-national studies of foreign relations law on a large scale. To the extent there have been comparative studies done of foreign relations law, they have been largely limited to relatively small-scale case studies. More comprehensive examination of the differences across nations in the ways in which they make international commitments is rare. This chapter aims to contribute to an emerging conversation about how best to carry out a more comprehensive examination of differences between states in the law governing their engagement in the world around them. It maps out five areas that offer opportunities and challenges for the study of comparative foreign relations law. First, the choice of methodology, whether quantitative or qualitative. Second, the under-representation of certain states in existing foreign relations scholarship. Third, the domestic political and institutional structures that shape the interplay between the legislative, executive, and judicial functions within states. Fourth, the role of geopolitics. Fifth, the chapter sounds a cautionary note about approaching international law through domestic law.
