About the Book:This book provides a conceptual and legal analysis of one of the most important challenges facing international organizations today: their exercise of sovereign powers. The book examines the exercise of sovereign powers by organizations such as the United Nations, the World Trade Organization, and the European Union. It makes a significant contribution to the content of the law that governs both the exercise of sovereign powers by international organizations and the relationships between organizations and their Member States. The book also tackles the fundamental question of what values should constrain international organizations in their exercise of sovereign powers.
