This is the first volume of essays arising from an exceptional series of seminars on criminal justice and human rights held earlier this year. The contributors, among them distinguished members of the judiciary and esteemed academics, have produced a set of vigorous and topical essays which will be essential reading for anyone concerned about criminal law, the future direction of the British criminal justice system, and the currently evolving changes in the position of the law on the critical areas of freedom of speech and expression as it moves to meet the challenges of swiftly shifting social, political and technological priorities and boundaries.
