Originally published in 1958, as a revised edition of The Development of International Law by the Permanent Court of International Justice (1934), this book received the Annual Award of the American Society of International Law in 1960. The achievement of the text is that, rather than attempting to provide a treatise on the organisation of international law, or a systematic digest of decisions made, it finds its basis in an appraisal of the international judicial process as a factor in the development of the law. From this position, ideas of great depth and subtlety are put forward regarding the nature of international justice and its possibilities. This is an important book that will be of value to anyone with an interest in its subject.
