'This volume is a timely and rich resource for modern constitutionalists. The essays are engaging, incisive and offer broad political and legal perspectives on one of the central questions in contemporary constitutional debates.'Professor Adrienne Stone, University of Melbourne, Australia'Recent developments in constitution-making and amending practices have implicated a range of methods of encouraging direct public participation, through crowd-sourcing, referenda, and more. This book examines the ways that these developments accentuate a range of fundamental issues dealing with the constituent power, sovereignty, and deliberation, through conceptual analysis and empirical studies. An important contribution to an increasingly important discussion.'Professor Mark Tushnet, Harvard Law School, USA‘This book reveals both good and bad practice, and problems of how to cope with citizen choices that are not mandated at formal election times. The book is timely and well written and appeals to a broad cross-section of readers from political science to constitutional lawyers. It is highly recommended.’Professor John McElldowney, Warwick University, UK
