Based on an analysis of the diplomatic practice of States, and decisions by national and international courts, this book explores the two central questions of the recognition of governments. These are namely: what are the meanings of the term 'recognition' and its variants in internationallaw; and what is the effect of recognition on the legal status of foreign authorities, and in particular of authorities in exile recognized as governments. The book is comprehensive in its analysis of the issues, and covers material which is of significant historical interest, as well as materialsuch as recent developments in Angola, Kuwait, and Haiti. Thus Talmon's book will hold great appeal for international law scholars and practitioners alike. It will also be of interest to diplomats and civil servants working in organizations such as the United Nations.
