6. International organizations
This chapter looks at international organizations, their differences to States, and their position within the international legal order. Today, international organizations exist in virtually all fields of transnational and global collective concern. In the broadest sense, they facilitate international cooperation in all areas from the harmonization of tariffs to the management of delicate ecosystems, and range in their scope from small bilateral commissions regulating transboundary resources to regional security and economic organizations, all the way to the universalist aspirations of the UN. The chapter then considers the question of establishing the legal personality of international organizations under international law, which must be distinguished from the question of whether an international organization may also hold legal personality under the domestic law of a State.
