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 thoughmuch 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.
