“Peter Bekker’s work on the legal position of intergovernmental organisations is an important contribution to this area of the law. … The strength of this book is its laying out of a clear and flexible framework for the consideration of organisational immunity. It is a reasonably technical discussion, although it is well illustrated by reference to practical examples, with particularly good use made of UN practice, and relevant work of the ILC. … [I]t is quite a practical guide for those creating and dealing with intergovernmental organisations.”
—Michelle Jarvis, Book Review, 16 Australian Yearbook of International Law 380 (1995)
