This book investigates and critically evaluates the concept of public benefit within charity law in the common law world. In the course of the study the book: provides a rich account of how the concept of public benefit has developed over time in charity law jurisprudence; deepens understanding of the aspects of public benefit that remain poorly understood even today; and suggests ways in which public benefit jurisprudence might develop in an orderly and principled way so as to better address some of the core concerns of charity law and the public policy objectives that lie behind it. The book includes contributions from world leading charity law experts and jurists. Each chapter reflects on a key aspect of public benefit jurisprudence in charity law. The topics have been chosen carefully to ensure coverage of most if not all of the large unresolved questions relating to public benefit in the common law world. Each chapter is accompanied by a comment, written by an academic expert or leading practitioner. The comments complement the chapters by critically engaging with those chapters and by offering different and thought-provoking perspectives on the subject matter of the chapters. The book will be of interest to academics working in law, philosophy, economics, sociology and political science. It will also provide a valuable resource for legal practitioners and judges, government officials, especially charity regulators, and in the not-for-profit sector itself.
