While regulatory institutions and strategies have been the subject of increasing academic attention, there has been limited application of regulatory theories to criminal justice scholarship. This collection of essays from a range of outstanding international scholars adopts a critical, inter-disciplinary approach, providing an innovative application of regulatory theory to the practice of criminal justice and offering suggestions for further research. Part I explores the aims and values of criminal justice and other regulatory networks and the synergies and tensions between these fields; Part II examines criminal justice as a regulatory force to control ‘deviant' and anti-social behaviour and Part III examines the regulation and oversight of criminal justice through the operation of prison inspectorates and explores notions of responsive justice.
