Giving an overview of the current state of the law and practice in relation to treaties, this edited work is an essential reference for practitioners and legal advisers involved in treaty negotiations or the interpretation of treaties. It also reflects on the current areas of disagreement or ambiguity.

From trade relations to greenhouse gases, from shipwrecks to cybercrime, treaties structure the rights and obligations of states, international organizations, and individuals. For centuries, treaties have regulated relations among nation states. Today, they are the dominant source of international law. Thus, being adept with treaties and international agreements is an indispensable skill for anyone engaged in international relations, including international lawyers, diplomats, international organization officials, and representatives of non-governmental organizations. The Oxford Guide to Treaties provides a comprehensive guide to treaties, shedding light on the rules and practices surrounding the making, interpretation, and operation of these instruments. Leading experts provide essays designed to introduce the law of treaties and offer practical insights into how treaties actually work. Foundational issues are covered, including what treaties are and when they should be used, alongside detailed analyses of treaty formation, application, interpretation, and exit. Special issues associated with treaties involving the European Union and other international organizations are also addressed. These scholarly treatments are complimented by a set of model treaty clauses. Real examples illustrate the approaches treaty-makers can take on topics such as entry into force, languages, reservations, and amendments. The Oxford Guide to Treaties thus provides an authoritative reference point for anyone studying or involved in the creation or interpretation of treaties or other forms of international agreement.

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.

International humanitarian law is the law that governs the conduct of participants during armed conflict. This branch of law aims to regulate the means and methods of warfare as well as to provide protections to those who do not, or who no longer, take part in the hostilities. It is one of the oldest branches of international law and one of enduring relevance today. The Oxford Guide to International Humanitarian Law provides a practical yet sophisticated overview of this important area of law. Written by a stellar line up of contributors, drawn from those who not only have extensive practical experience but who are also regarded as leading scholars of the subject, the text offers a comprehensive and authoritative exposition of the field. The Guide provides professionals and advanced students with information and analysis of sufficient depth to enable them to perform their tasks with understanding and confidence. Each chapter illuminates how the law applies in practice, but does not shy away from the important conceptual issues that underpin how the law has developed. It will serve as a first port of call and a regular reference work for those interested in international humanitarian law.

This Oxford Handbook ambitiously seeks to lay the groundwork for the relatively new field of comparative foreign relations law. Comparative foreign relations law compares and contrasts how nations, and also supranational entities (for example, the European Union), structure their decisions about matters such as entering into and exiting from international agreements, engaging with international institutions, and using military force, as well as how they incorporate treaties and customary international law into their domestic legal systems. The legal materials that make up a nation's foreign relations law can include constitutional law, statutory law, administrative law, and judicial precedent, among other areas. This book consists of 46 chapters, written by leading authors from around the world. Some of the chapters are empirically focused, others are theoretical, and still others contain in-depth case studies. In addition to being an invaluable resource for scholars working in this area, the book should be of interest to a wide range of lawyers, judges, and law students. Foreign relations law issues are addressed regularly by lawyers working in foreign ministries, and globalization has meant that domestic judges, too, are increasingly confronted by them. In addition, private lawyers who work on matters that extend beyond their home countries often are required to navigate issues of foreign relations law. An increasing number of law school courses in comparative foreign relations law are also now being developed, making this volume an important resource for students as well. Comparative foreign relations law is a newly emerging field of study and teaching, and this volume is likely to become a key reference work as the field continues to develop.

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.

The Oxford Handbook of the History of International Law provides an authoritative and original overview of the origins, concepts, and core issues of international law. The first comprehensive Handbook on the history of international law, it is a truly unique contribution to the literature of international law and relations. Pursuing both a global and an interdisciplinary approach, the Handbook brings together some sixty eminent scholars of international law, legal history, and global history from all parts of the world. Covering international legal developments from the 15th century until the end of World War II, the Handbook consists of over sixty individual chapters which are arranged in six parts. The book opens with an analysis of the principal actors in the history of international law, namely states, peoples and nations, international organisations and courts, and civil society actors. Part Two is devoted to a number of key themes of the history of international law, such as peace and war, the sovereignty of states, hegemony, religion, and the protection of the individual person. Part Three addresses the history of international law in the different regions of the world (Africa and Arabia, Asia, the Americas and the Caribbean, Europe), as well as 'encounters' between non-European legal cultures (like those of China, Japan, and India) and Europe which had a lasting impact on the body of international law. Part Four examines certain forms of 'interaction or imposition' in international law, such as diplomacy (as an example of interaction) or colonization and domination (as an example of imposition of law). The classical juxtaposition of the civilized and the uncivilized is also critically studied. Part Five is concerned with problems of the method and theory of history writing in international law, for instance the periodisation of international law, or Eurocentrism in the traditional historiography of international law. The Handbook concludes with a Part Six, entitled "People in Portrait", which explores the life and work of twenty prominent scholars and thinkers of international law, ranging from Muhammad al-Shaybani to Sir Hersch Lauterpacht. The Handbook will be an invaluable resource for students and scholars of international law. It provides historians with new perspectives on international law, and increases the historical and cultural awareness of scholars of international law. It is the standard reference work for the global history of international law.
