This book analyses the criminalisation of the possession of extreme pornography through ss 63-68 of the Criminal Justice and Immigration Act 2008. It documents the legislative history of the offence and offers a criminological perspective on the role of the media in the construction of the extreme pornography problem. It evaluates the elements of the s 63 offence and critically reflects upon their weaknesses. Moreover, the book presents an up-to-date account of the number of prosecutions initiated and convictions obtained under s 63 since it came into force, alongside an exploration into the corresponding sentencing trends. The first study of its kind in England and Wales since the controversial legal provisions at issue came into effect in 2009, this book contributes new evidence to the application of the extreme pornography provisions and will play an important role in shaping debates on the prosecution of similar offences in the coming years. This book will serve as an invaluable resource to all those with an interest in law, criminology, sociology of deviance, sexuality and pornography studies.
