This work is based on long-term research into State practice combined with the development of a theoretical foundation of such practice, which explains the behaviour of states as subject to clear legal restraints. It argues that state practice is not compatible with traditional concepts of international law and that a fresh approach is required.

Undoubtedly one of the paragons of public international law in contemporary times, Colin Warbrick is truly held in high esteem by his peers at home and abroad. His breadth of knowledge is reflected in a large number of scholarly works and in his appointment as a Specialist Adviser to the Select Committee on the Constitution of the House of Lords and as a consultant to both the Council of Europe and OSCE. This "festschrift" celebrates on his retirement as Barber Professor of Jurisprudence at Birmingham University, his extraordinary talent and academic career by bringing together a group of eminent judges, practitioners and academics to write on international human rights, international criminal justice and international order and security, fields in which Professor Warbrick has left an indelible mark.

When studying international law there is often a risk of focusing entirely on the content of international rules (i.e. regimes), and ignoring why these regimes exist and to what extent the rules affect state behavior. Similarly, international relations studies can focus so much on theories based on the distribution of power among states that it overlooks the existence and relevance of the rules of international law. Both approaches hold their dangers. The overlooking of international relations risk assuming that states actually follow international law, and discounting the specific rules of international law makes it difficult for readers to understand the impact of the rules in more than a superficial manner. This book unifies international law and international relations by exploring how international law and its institutions may be relevant and influence the course of international relations in international trade, protection of the environment, human rights, international criminal justice and the use of force. As a study on the intersection of power and law, this book will be of great interest and use to scholars and students of international law, international relations, political science, international trade, and conflict resolution.

Shirley Scott explains how the USA has benefited from continuity in its strategic engagement with international law.

The world is poised for another important transition. The United States is dealing with the impact of the Afghan and Iraq wars, the use of torture and secret detention, Guantanamo, climate change, nuclear proliferation, weakened international institutions, and other issues related directly or indirectly to international law. The world needs an accurate account of the important role of international law and The Power and Purpose of International Law seeks to provide it. Mary Ellen O'Connell explains the purpose of international law and the power it has to achieve that purpose. International law supports order in the world and the attainment of humanity's fundamental goals of peace, prosperity, respect for human rights, and protection of the natural environment. These goals can best be realized through international law, which uniquely has the capacity to bind even a superpower of the world. By exploring the roots and history of international law, and by looking at specific events in the history of international law, this book demonstrates the why and the how of international law and its enforcement. It directly confronts the notion that international law is "powerless" and that working within the framework of international law is useless or counter-productive. As the world moves forward, it is critical that both leaders and their citizens understand the true power and purpose of international law and this book creates a valuable resource for them to aid their understanding. It uses a clear, compelling style to convey topical, informative and cutting-edge information to the reader.

Foucault's challenging view of power and knowledge as the basis for interpreting the international system forms the central themes of this book. As the application of international law expands and develops this book considers how Foucault's approach may create a viable framework that is not beset by ontological issues. With International law essentially stuck within an older framework of outmoded statist approaches, and overly broad understanding of the significance of external actors such as international organizations; current interpretations are either rooted in a narrow attempt to demonstrate a functioning normative structure or interpret developments as reflective of some emerging and somewhat unwieldy ethical order. This book therefore aims to ameliorate the approaches of a number of different 'schools' within the disciplines of international law and international relations, without being wedded to a single concept. Current scholarship in international law tends to favour an unresolved critique, a utopian vision, or to refer to other disciplines like international relations without fully explaining the significance or importance of taking such a step. This book analyses a variety of problems and issues that have surfaced within the international system and provides a framework for consideration of these issues, with a view towards accounting for ongoing developments in the international arena.

A runner-up for the 2018 Chadwick Alger Prize, International Studies Association's International Organization Section, this provocative reassessment of the rule of law in world politics examines how and why governments use and manipulate international law in foreign policy.
