International Law provides a comprehensive theoretical examination of the key areas of international law. In addition to classic cases and materials, Carlo Focarelli addresses the latest relevant international practice to illustrate contemporary themes and trends in international law and to examine its most topical challenges. The key features of this textbook include: • A unitary – ‘systemic’ and ‘realist-constructivist’ – theoretical illustration of international law, essential to an understanding of how international law works in practice and how it can, or should, be changed • A clear logical structure and thorough cross-referencing for accessible, systemic and consistent learning • Up-to-date bibliographies at the end of each chapter and academic commentary on the very latest cases, covering all aspects of international law. Insightful and topical, this textbook will be an invaluable teaching resource for students of law, political science, and international relations.
