This concise book is an introduction to the role of international law in international relations. Written for lawyers and non-lawyers alike, the book first appeared in 1928 and attracted a wide readership. This new edition builds on Brierly's scholarship and his idea that law must serve a social purpose. Previous editions of The Law of Nations have been the standard introduction to international law for decades, and are widely popular in many different countries due to the simplicity and brevity of the prose style. Providing a comprehensive overview of international law, this new version of the classic book retains the original qualities and is again essential reading for all those interested in learning what role the law plays in international affairs. The reader will find chapters on traditional and contemporary topics such as: the basis of international obligation, the role of the UN and the International Criminal Court, the emergence of new states, the acquisition of territory, the principles covering national jurisdiction and immunities, the law of treaties, the different ways of settling international disputes, and the rules on resort to force and the prohibition of aggression.

Due diligence obligations are typically described by scholars and practitioners as 'elusive', 'weak', and difficult to pin down in the abstract. Challenging these assumptions, this book offers a systematic reconstruction of the foundations of due diligence obligations of states and explores their nature, rationale, content and scope of operation in international law. Tackling due diligence from a general perspective, this book seeks to complement scholarly studies on public international law obligations and their theory. This book will be relevant for academics, practitioners, graduate students across international law and anyone seeking to better conceptualise due diligence under international law and understand how due diligence obligations are operationalised in practice.

Beyond Human Rights, previously published in German and now available in English, is a historical and doctrinal study about the legal status of individuals in international law.

This rich and remarkable volume offers an overview of the most important schools, movements and trends which make up the theoretical landscape of contemporary international law, as well as the works of over 500 authors. It moves beyond generalization and examines how the relevant literature deals with the basic issues of the international legal system, such as international obligations, legitimacy, compliance, unity and universality, the rule of law, human rights, use of force and economics. It offers insights into the addressees (the state, international organizations, individuals and other private persons), and the construction of international law, including law-making, the relationship between norms, and interpretation. Moreover, it widens the discourse by addressing old, yet enduring, as well as new concerns about the functioning of the international legal system, and presents views of non-international lawyers and political scientists regarding that system. It is a valuable analysis for researchers, students, and practitioners.

One of the most prominent and urgent problems in international governance is how the different branches and norms of international law interact and what to do in the event of conflict. With no single 'international legislator' and a multitude of states, international organisations and tribunals making and enforcing the law, the international legal system is decentralised. This leads to a wide variety of international norms, ranging from customary international law and general principles of law, to multilateral and bilateral treaties on trade, the environment, human rights, the law of the sea, etc. Pauwelyn provides a framework on how these different norms interact, focusing on the relationship between the law of the World Trade Organisation (WTO) and other rules of international law. He also examines the hierarchy of norms within the WTO treaty. His recurring theme is how to marry trade and non-trade rules, or economic and non-economic objectives at the international level.

Examining the fulfilment of international obligations by subjects of this law, this book explores the normative and functional links between the sources and rules of international law on the one hand, and the responsibility for violating international law on the other. In the sphere of law-making, the theory of obligations allows for a more precise and considered formulation of international obligations. It has the potential to enable subjects of international law to behave more rationally, allowing deeper reflection on whether to take on obligations and how to properly perform them. This book proposes a new approach to the issue of the proper operation of international law, with the theory of obligations at its heart. Linking the institutions and concepts of international law into a rational whole, the book offers an analysis of the operation of international law and the behaviour of its subjects to develop a framework for ensuring the ultimate effectiveness of international law. Analysing sources of law including treaties and common law, alongside the resolutions of international organisations, this book demonstrates the practical application of the subject with reference to the jurisprudence of international courts and other bodies. The volume will be of interest to scholars, students, and practitioners concerned with international law – its creation, performance, application, compliance, and enforcement.
