PluriCourts Lunch seminar Between Universalism and State Consent: Regional Customary International Law and the International Court of Justice

PluriCourts Lunch seminar with Freya Baetens


Regionalism—or regional international law—captures the set of rules that apply in the relations between States in a certain region. It can only be defined by reference to—and potentially in contradistinction to—universalism. At its heart lies a reaction against the assertion of an international legal system with universal application—perhaps ironically, a system of a distinctive regional (European) origin itself.

This paper examines how the International Court of Justice (ICJ) has addressed claims based on regional international law. It will be shown that, although regionalist considerations are recognised by the ICJ, they are first converted to the classic currencies of international law: universality and State consent.


PluriCourts Lunch Seminars are a forum for pluridisciplinary discussion of core issues relating to international courts and tribunals. PluriCourts scholars or invited speakers present new and ongoing research or comment on current questions. The seminars are open to everyone.
