This book is an erudite and impressive statement of what diplomatic law actually is and what, presumably, it may become, bearing in mind such ongoing controversies as the tension between the principle of non-interference in the affairs of a particular country - and the duty to promote and champion the basic tenets of human rights. - Phillip Taylor MBE and Elizabeth Taylor, Richmond Green Chambers

Review from previous edition ... a cornerstone in any large or small library collection dealing with diplomats... It remains the 'must have' work for all members of the worldwide diplomatic community... a handy collection of cases from national courts... conveniently organised by Article. - American Society of International Law

questions of diplomatic law are routinely answered by asking, "What does Denza say?" The Oxford University Press fortunately recognized Denza as a classic and supported a second edition, published in 1998 ... This breadth and depth of resources ensures that Denza will remain the preeminent English language authority in its field. Happily, now that it has been published in a beautiful typeface on quality paper, Denza finally looks like the definitive work that it is - Catherine W. Brown, US Department of State, American Journal of International Law

First published in 1976, Denza's Diplomatic Law has become the classic study on the Vienna Convention on Diplomatic Relations 1961. No study of diplomatic law or, indeed, the subject of diplomatic relations in general would be complete without reference to Denza's work. Having produced such an authoritative work, it must have been with no small degree of trepidation that Denza approached the prospects of improving upon that work 22 years later. However, there is no doubt that Denza has succeeded in her task ... The inclusion of the new material is pervasive throughout the book ... there can be little doubt that Diplomatic Law will remain the leading authority on the Vienna Convention for many years to come. It is an essential purchase for all practitioners of diplomacy and academics involved in the study of diplomacy in general and diplomatic law in particular. - J Craig Barker, International and Comparative Law Quarterly Vol 48

well structured, it is easy to use and has a comprehensive and useful table of cases dealing with the different interpretation and application of the Convention ... during my readings I recognized many topics from my active service and the book will be a most welcome tool in my future professional life ... a useful and comprehensive source of practical guidance for diplomats as well as other practitioners. And I am sure it will be equally appreciated by scholars and students of public international law as a source of reference and learning. - Anders C Hougaard, EJIL 10 (1999)

Rarely is an international law reference text, let alone an article-by-article commentary on a convention, both authoritative and entertaining, Eileen Denza's third edition of Diplomatic Law is, however, an exception - Lance Bartholomeusz, UN Relief and Works Agency for Palestine, EJIL 20
