This monograph examines international legal regulation, analyses how it interacts with non-legal factors, and seeks to understand and confront the alleged inherent ambiguity and indeterminacy.

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 lawyers have long recognised the importance of interpretation to their academic discipline and professional practice. As new insights on interpretation abound in other fields, international law and international lawyers have largely remained wedded to a rule-based approach, focusing almost exclusively on the Vienna Convention on the Law of Treaties. Such an approach neglects interpretation as a distinct and broader field of theoretical inquiry. Interpretation in International Law brings international legal scholars together to engage in sustained reflection on the theme of interpretation. The book is creatively structured around the metaphor of the game, which captures and illuminates the constituent elements of an act of interpretation. The object of the game of interpretation is to persuade the audience that one's interpretation of the law is correct. The rules of play are known and complied with by the players, even though much is left to their skills and strategies. There is also a meta-discourse about the game of interpretation - 'playing the game of game-playing' - which involves consideration of the nature of the game, its underlying stakes, and who gets to decide by what rules one should play. Through a series of diverse contributions, Interpretation in International Law reveals interpretation as an inescapable feature of all areas of international law. It will be of interest and utility to all international lawyers whose work touches upon theoretical or practical aspects of interpretation.

This text analyses the law of treaty interpretation as applied by the WTO Appellate Body. By focusing on the development of the law in practice, and the intersection of customary international law principles with the growth of WTO specific law, the book reveals the complexity of treaty interpretation in a major international law forum.

"As the book clearly explains, there are situations in which questions of contract law need to be examined by investment tribunals - mainly as preliminary or incidental questions, to determine issues such as contract liability or breach of contract, that in turn are assumed as a basis for the issues of investment law in dispute"--

Fundamentals of Public International Law, by Giovanni Distefano, provides an overview of public international law’s main principles and fundamental institutions. By introducing the foundations of the legal reasoning underlying public international law, the extensive volume offers essential tools for any international lawyer, regardless of the specific field of specialization. Dealing expansively with subjects, sources and guarantees of international law, university students, scholars and practitioners alike will benefit from the book’s treatment of what has been called the “Institutes” of public international law.
