The Emergence of International and Regional Value Systems as a Manifestation of the Emerging International Constitutional Order

Abstract

This article explores the composition of the emerging international value system, including its hierarchical components. It also contrasts this fragile international value system with the more strongly developed European value system (European public order), as concretized by the European Convention on Human Rights and the jurisprudence of the European Court of Human Rights. It first argues that international human rights norms constitute the ‘core content’ of a constantly evolving and layered international value system. Within this value system, a special but fragile hierarchical status is granted to those human rights norms that qualify as jus cogens and/or erga omnes norms. Thereafter it explores the manner in which the European Court of Human Rights has concretized the normative superiority of obligations under the European Convention on Human Rights for member states vis-à-vis other norms of public international law, to the extent that a conflict between these norms arises. It concludes by examining whether these developments could also strengthen the international value system through a spill-over effect via the work of international human rights bodies and national courts. This, in turn, would strengthen the ability of the international value system to determine the outcome of conflicts between international obligations stemming from different international regimes. © 2006, Foundation of the Leiden Journal of International Law.
