This second edition pursues the same aims as the first: to provide a clear and relatively short statement of the most important rules concerning judicial control of governmental administrative activity, and to provide a wider framework for understanding those rules. This framework is provided by considering the constitutional context of judicial control; the relationship between judicial control and other mechanisms for checking administrative activity; and the impact of judicial control on the agencies subject to it. What emerges clearly from considering judicial control in this wider context is that the role of the court in adjudicating complaints about governmental administrative action is not that of neutral arbiter but that of active participant in the public decision-making process. It is hoped that this book will provide readers with a concise but critical analysis of the law. This book is aimed at under-graduate law students studying administrative law as a second or third-year option or constitutional and administrative law as a first or second year compulsory subject.
