Welcome to the website of the Centre for the Law of EU External Relations (CLEER). Since the start of the European integration process, the legal orders of the EC/EU and the Member States have co-existed and been influenced by international law. Conversely, the EU is a regulatory superpower with a policy lead in many areas. But the EU has failed to pull its political weight in the world. New developments at the level of the EU treaties, secondary legislation and case-law create conflicts with the evolving international legal order.
