Protecting Reliance

Michael Spence is a Fellow and Tutor in Law of St Catherine's College, Oxford.

This well-written book deserves a wide readership. I would recommend it to all those involved in the practice or teaching of the law of obligations and also to legal taxonomists. To the legal practicioner in search of the most appropriate authority to support a particular aspect of equitable estoppel, the rich source of cases in the footnotes (including unreported Australian decisions) is a bonus. D Y K Fung Journal of Contract Law July 2001 One can only admire this book's brevity, clarity, and purpose... This provocative book will no doubt be the subject of much discussion. J.E.
