In When International Law Works, Professor Tai-Heng Cheng transcends current debates about whether international law is really law by focusing on the reasons for complying with or deviating from international laws and other informal norms, whether or not they are 'law.' Cheng presents a new framework to guide decision makers when they confront an international problem that implicates the oftencompeting policies and interests of their own communities and global order. Instead of advocating for or against international law, Cheng acknowledges both its benefits and shortcomings in order to present practical ways to decide whether compliance in a given circumstance is beneficial, moral, or necessary, and to adjust international law to meet the contemporary challenges of global governance. In this manner, Cheng shows how it is possible for decision makers to take international law and its limitations seriously. To test his theory, Cheng provides detailed case studies from recent events, ranging from the current global economic crisis to jihadist terrorism. This wideranging research demonstrates how his proposal for approaching international law would work in a real crisis, and sets this book apart from scholarship that focuses only on theory or isolated fields of international law. Through a critical combination of theory and practice, When International Law Works gives policymakers, judges, arbitrators, scholars, and students practical and thought-provoking guidance on how to face new global problems. In doing so, this new book challenges readers to rethink the role of law in an increasingly crisis-driven world.

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.

For some time, the word 'crisis' has been dominating international political discourse. But this is nothing new. Crisis has always been part of the discipline of international law. History indeed shows that international law has developed through reacting to previous experiences of crisis, reflecting an agreement on what it takes to avoid their repetition. However, human society evolves and challenges existing rules, structures, and agreements. International law is confronted with questions as to the suitability of the existing legal framework for new stages of development. Ulrich and Ziemele here bring together an expert group of scholars to address the question of how international law confronts crises today in terms of legal thought, rule-making, and rule-application. The editors have characterized international law and crisis discourse as one of a dialectical nature, and have grouped the articles contained in the volume under four main themes: security, immunities, sustainable development, and philosophical perspectives. Each theme pertains to an area of international law which at the present moment in time is subject to notable challenges and confrontations from developments in human society. The surprising general conclusion which emerges is that, by and large, the international legal system contains concepts, principles, rules, mechanisms and formats for addressing the various developments that may prima facie seem to challenge these very same elements of the system. Their use, however, requires informed policy decisions.

Filling a conspicuous gap in the legal literature, Andrew T. Guzman's How International Law Works develops a coherent theory of international law and applies that theory to the primary sources of law, treaties, customary international law, and soft law. Starting where most non-specialists start, Guzman looks at how a legal system without enforcement tools can succeed. If international law is not enforced through coercive tools, how is it enforced at all? And why would states comply with it?--Publisher.

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.

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.
