The existence of a hierarchy between the different international legal rules is increasingly being debated. This volume will identify the extent to which judicial bodies and domestic courts contribute to an emerging normative hierarchy within international law, based on the primacy of human rights.

This Oxford Handbook examines the sources of international law, how the understanding of sources changed throughout the history of international law; how the main legal theories understood sources; the relationship between sources and the legitimacy of international law; and how sources differ across the various sub-areas of international law.

International relations are generally understood as a realm of anarchy in which countries lack any superior authority and interact within a Hobbesian state of nature. In Hierarchy in International Relations, David A. Lake challenges this traditional view, demonstrating that states exercise authority over one another in international hierarchies that vary historically but are still pervasive today. Revisiting the concepts of authority and sovereignty, Lake offers a novel view of international relations in which states form social contracts that bind both dominant and subordinate members. The resulting hierarchies have significant effects on the foreign policies of states as well as patterns of international conflict and cooperation. Focusing largely on U.S.-led hierarchies in the contemporary world, Lake provides a compelling account of the origins, functions, and limits of political order in the modern international system. The book is a model of clarity in theory, research design, and the use of evidence. Motivated by concerns about the declining international legitimacy of the United States following the Iraq War, Hierarchy in International Relations offers a powerful analytic perspective that has important implications for understanding America's position in the world in the years ahead.

3.1 Custom and "Soft Law"

This book offers a comparative analysis of the institutional law of public international organizations, covering issues such as membership, institutional structure, decisions and decision-making, legal status, privileges and immunities. It has been designed to appeal to both academics and practitioners.

The hierarchy of states presents Ian Clark's Reform and resistance in the international order, a well-established text on international relations first published in 1980, in a completely revised form. Combining a detailed examination of theory with a full account of historical developments, Dr Clark analyses the nature of international order - the hierarchical state system - and its potential for reform. The theory of international order is explored tracing two traditions of thought epitomised in the writings of Kant and Rousseau, whilst in a historical survey Dr Clark covers the main attempts to implement international order since 1815 and includes such aspects as concert diplomacy, alliance systems, international organisations as well as such informal understandings as nuclear deterrence, crisis management and spheres of influence. This revised edition contains two new chapters - one on international/world order issues and the other on 'macro' changes between 1815 and 1990. Dr Clark has updated his discussion on the course of superpower relations and most of the material on the post-1945 period is introduced in this edition for the first time.
