UN Charter

This chapter examines the powers or competences of the United Nations as a separate legal entity. Its possession of legal personality, its specialized agencies, and some of the separate legal entities in the UN family are concepts that are related but distinct from the powers of these bodies. The possession of international legal personality means that these bodies have their own rights and duties, and powers vested in them in their own right. However, the possession of legal personality does not define the particular powers of the organization, nor does it mean that they have plenary competence under international law or in municipal legal systems. The chapter discusses the relationship to legal personality; nature and scope; purposes and principles of the organization; division of competence between principal organs and subsidiary organs; domestic jurisdiction limitation of Article 2(7); substantive content of powers internationally and in domestic law; consequences of ultra vires acts.
