The Nature of International Law provides a comprehensive analytical account of international law within the prototype theory of concepts.

This title was first published in 2002: The purpose if this volume is to provide a map of some of the great theoretical debates within the discipline of international law. The essays included are structured as dialogues between international legal theorists on concrete subjects such as democracy, gender, compliance, sovereignty and justice. They represent the most interesting theoretical work undertaken in international law.

This fully updated and revised edition explores the evolution, nature and function of international law in world politics.

Some legal rules are not laid down by a legislator but grow instead from informal social practices. In contract law, for example, the customs of merchants are used by courts to interpret the provisions of business contracts; in tort law, customs of best practice are used by courts to define professional responsibility. Nowhere are customary rules of law more prominent than in international law. The customs defining the obligations of each State to other States and, to some extent, to its own citizens, are often treated as legally binding. However, unlike natural law and positive law, customary law has received very little scholarly analysis. To remedy this neglect, a distinguished group of philosophers, historians and lawyers has been assembled to assess the nature and significance of customary law. The book offers fresh insights on this neglected and misunderstood form of law.

This illuminating book explores the nature of international humanitarian law (IHL), so doing by asking whether it should be seen as a permissive or a restrictive regime. An experienced lawyer in the field, Anne Quintin offers an in-depth expert analysis of this highly debated topic, revealing the true nature of IHL and concluding that whilst IHL initially developed as a restrictive regime composed of prohibitions and prescriptions, it nevertheless contains within it rare permissions that allow states to act.

Interest in international law has increased greatly over the past decade, largely because of its central place in discussions such as the Iraq War and Guantanamo, the World Trade Organisation, the anti-capitalist movement, the Kyoto Convention on climate change, and the apparent failure of the international system to deal with the situations in Palestine and Darfur, and the plights of refugees and illegal immigrants around the world. This Very Short Introduction explains what international law is, what its role in international society is, and how it operates. Vaughan Lowe examines what international law can and cannot do and what it is and what it isn't doing to make the world a better place. Focussing on the problems the world faces, Lowe uses terrorism, environmental change, poverty, and international violence to demonstrate the theories and practice of international law, and how the principles can be used for international co-operation.
