Conventionality Control Between International and Constitutional Law: the Viewpoint of a Comparativist

This contribution addresses conventionality control in its double dimension, encompassing international law and constitutional law. It focuses on the comparative methodological issues when equating the Inter-American and the European systems of protection of human rights, taking into account the progressive “Europeanization” of the former’s case law. Then, it critically examines the question of judicial authority of domestic and international courts in multilevel systems, to raise a few points concerning the complex relationship between international courts and states.
