This book examines the justice gap and trial process for sexual assault against both adults and children in two jurisdictions: England and Wales and New South Wales, Australia. Drawing on decades of research, it investigates the reality of the policing and prosecution of sexual assault offences - often seen as one of the 'hardest crimes to prosecute' - across two similar jurisdictions. Despite the introduction of many reform options, satisfactory outcomes for victims and the public are still difficult to obtain. Cossins takes a new approach by examining the structures of power within the trial process, to show how and at what points that process is weighted against complainants of sexual assault, in order to make thought-out suggestions for reform. She argues that this justice gap is a result of myths and misconceptions about rape which can be eliminated by a radical replacement of the adversarial system with a trauma-informed system. This book takes into consideration the psychological literature and speaks to students and academics across subjects including law, criminology, gender studies and psychology, and to practitioners in law and victim services, and policy-makers.
