This book explores the process of treaty modification by subsequent practice, explaining how such practice can significantly revise treaty obligations or even create new ones, allowing evolution of the law.

Under the relevant rules of international law, treaties are interpreted in accordance with the ordinary meaning of the language they use, their object and purpose, and the intention of the drafters, but also in light of the subsequent practice of its parties. This subsequent practice can shed light on articles whose meaning is ambiguous and subsequent agreement can even alter the meaning of treaty provisions. At a time when many of the most important international treaties are more than fifty years old, subsequent practice plays an increasingly important role in their interpretation. Treaties and Subsequent Practice discusses the role and relevance of this subsequent practice in the process of dynamic treaty interpretation. The book provides a comprehensive treatment of this topic by eminent commentators, combining contributions which focus on practical cases with chapters examining the theoretical underpinnings of treaty interpretation. The concept of subsequent practice is situated in the more general context of treaty law and international law, looking at different cases and doctrinal questions to assess its policy dimensions. The book addresses the question of whether subsequent practice plays a more or less significant role in different areas of international law, and whether it can be employed as a partial substitute for formal treaty amendments. It also includes two previously unpublished reports issued by the International Law Commission's Study Group on this topic.

Human activities have taken place in the world's oceans and seas for most of human history. With such a vast number of ways in which the oceans can be used for trade, exploited for natural resources and fishing, as well as concerns over maritime security, the legal systems regulating the rights and responsibilities of nations in their use of the world's oceans have long been a crucial part of international law. The United Nations Convention on the Law of the Sea comprehensively defined the parameters of the law of the sea in 1982, and since the Convention was concluded it has seen considerable development. This Oxford Handbook provides a comprehensive and original analysis of its current debates and controversies, both theoretical and practical. Written by over forty expert and interdisciplinary contributors, the Handbook sets out how the law of the sea has developed, and the challenges it is currently facing. The Handbook consists of forty chapters divided into six parts. First, it explains the origins and evolution of the law of the sea, with a particular focus upon the role of key publicists such as Hugo Grotius and John Selden, the gradual development of state practice, and the creation of the 1982 UN Convention. It then reviews the components which comprise the maritime domain, assessing their definition, assertion, and recognition. It also analyses the ways in which coastal states or the international community can assert control over areas of the sea, and the management and regulation of each of the maritime zones. This includes investigating the development of the mechanisms for maritime boundary delimitation, and the decisions of the International Tribunal for the Law of the Sea. The Handbook also discusses the actors and intuitions that impact on the law of the sea, considering their particular rights and interests, in particular those of state actors and the principle law of the sea institutions. Then it focuses on operational issues, investigating longstanding matters of resource management and the integrated oceans framework. This includes a discussion and assessment of the broad and increasingly influential integrated oceans management governance framework that interacts with the traditional law of the sea. It considers six distinctive regions that have been pivotal to the development of the law of the sea, before finally providing a detailed analysis of the critical contemporary issues facing the law of the sea. These include threatened species, climate change, bioprospecting, and piracy. The Handbook will be an invaluable and thought-provoking resource for scholars, students, and practitioners of the law of the sea.

This is the first comprehensive account of the modern international law of treaty interpretation expressed in 1969 Vienna Convention, Articles 31-33. As stated by the anonymous referee, it is the most theoretically advanced and analytically refined work yet accomplished on this topic. The style of writing is clear and concise, and the organisation of the book meets the demands of scholars and practitioners alike.

Helps the reader better understand what it is that international lawyers do when interpreting a treaty.

The rules of treaty interpretation codified in the 'Vienna Convention on the Law of Treaties' now apply to virtually all treaties, in an international context as well as within national legal systems, where treaties have an impact on a large and growing range of matters. The rules of treaty interpretation differ somewhat from typical rules for interpreting legal instruments and legislation within national legal systems. Lawyers, administrators, diplomats, and officials at international organisations are increasingly likely to encounter issues of treaty interpretation which require not only knowledge of the relevant rules of interpretation, but also how these rules have been, and are to be, applied in practice. Since the codified rules of treaty interpretation came into decree, there is a considerable body of case-law on their application. This case-law, combined with the history and analysis of the rules of treaty interpretation, provides a basis for understanding this most important task in the application of treaties internationally and within national systems of law. Any lawyer who ever has to consider international matters, and increasingly any lawyer whose work involves domestic legislation with any international connection, is at risk nowadays of encountering a treaty provision which requires interpretation, whether the treaty provision is explicitly in issue or is the source of the relevant domestic legislation. This fully updated new edition features case law from a broader range of jurisdictions, and an account of the work of the International Law Commission in its relation to interpretative declarations. This book provides a guide to interpreting treaties properly in accordance with the modern rules.

The book examines treaty law from the angle of types of motion, combining theory with practical examples and empirical data.

In international law, the refugee definition enshrined in Article 1A(2) of the Refugee Convention and its 1967 Protocol is central. Yet, seven decades on, the meaning of its key terms are widely seen as unclear. The Refugee Definition in International Law asks whether we must continue to accept this or whether a systematic legal analysis can shed new light on this important term. The volume addresses several framework questions concerning approaches to definition, interpretation, ordering, and the interrelationship between the definition's different elements. Each element is then analysed in turn, applying Vienna Convention of the Law of Treaties rules in systematic fashion. Each chapter evaluates the main disputes that have arisen and seeks to distil basic propositions that are widely agreed, as well as certain suggested propositions for resolving ongoing debates. In the final chapter, the basic propositions are assembled to demonstrate that in fact there is now more clarity about the definition than many think and that considerable progress has been made toward achieving a working definition.

The 1969 and 1986 Vienna Conventions on the Law of Treaties are essential components of the international legal order. This is the first Commentary on their provisions, containing thorough and well-structured analyses of each of their Articles. It draws on preparatory works and practice and is written by a large collection of experts from the field
