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.

International Law is both an introduction to the subject and a critical consideration of its central themes and debates. The opening chapters of the book explain how international law underpins the international political and economic system by establishing the basic principle of the independence of States, and their right to choose their own political, economic, and cultural systems. Subsequent chapters then focus on considerations that limit national freedom of choice (e.g. human rights, the interconnected global economy, the environment). Through the organizing concepts of territory, sovereignty, and jurisdiction the book shows how international law seeks to achieve an established set of principles according to which the power to make and enforce policies is distributed among States.

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 book challenges the idea that international law looks the same from anywhere in the world. Instead, how international lawyers understand and approach their field is often deeply influenced by the national contexts in which they lived, studied, and worked. International law in the United States and in the United Kingdom looks different compared to international law in China and Russia, though some approaches (particularly Western, Anglo-American ones) are more influential outside their borders than others. Given shifts in geopolitical power and the rise of non-Western powers like China, it is increasingly important for international lawyers to understand how others coming from diverse backgrounds approach the field. By examining the international law academies and textbooks of the five permanent members of the UN Security Council, Roberts provides a window into these different communities of international lawyers, and she uncovers some of the similarities and differences in how they understand and approach international law.

In the freshest new international law text in 20 years, Christopher C. Joyner offers a critical assessment of international legal rules in the early 21st century as they are applied by governments to the real world. Looking at concepts and principles, processes and critical problems, Joyner steers clear of an old-time case method approach, preferring to treat issues thematically. He shows the challenges of international law in terms of peace, security, human rights, the environment, and economic justice. Particular features of the book include engaging vignettes, clearly defined key terms, and special coverage of emerging topics including common spaces; international criminal law; rules, norms, and regimes; and trade relations and commercial exchange. Through it all, Joyner maintains an intent focus on the role of the individual in the evolving international legal order.

This book asks what the legal definition of an international organization is by examining how they create particular legal systems that derive from international law, and analysing the systems of governance in these organizations.

This book explores international law as a social construct by analysing its social foundations and by re-conceptualizing the way in which it is commonly understood. It asks what law is and how it works in society, and shows why it is worth to struggle for new and better-working rules in the international legal order.
