First published in 1965, this book was primarily intended to serve as a work of practical value to Foreign Offices and Diplomatic Missions, but it has proved equally useful to the practitioners and students of international law. The third revised edition, which is almost a new book, incorporates current developments and state practice, including judicial decisions in a variety of fields of topical interest, and also deals with current issues of interest in diplomatic relations. The author has headed a forty-nation inter-governmental organization for the past 16 years and had earlier served as Legal Adviser to the Indian Ministry of External Affairs under Prime Minister Nehru. He has drawn a great deal on his personal experience, gathered over almost 3 decades, in dealing with various problems and issues. "A Diplomat's Handbook of International Law and Practice" is thus a work of unique practical value. The book is divided into three parts. Part I deals with the establishment and conduct of diplomatic relations, the functions of diplomatic agents, diplomatic immunities and privileges including those of non-diplomatic and sub-ordinate staff. Part II concerns consular functions, immunities and non privileges. Part III contains a study of some selected topics of international law which are of particular interest to foreign service officers.
