Abstract
This chapter examines the source and changing nature of the fundamental principles of criminal justice. It begins by considering a process of change for criminal justice featuring four factors labelled as ‘game changers’ — principles, policies, practices, and people — with a particular focus on principles. It then discusses the importance of the rule of law doctrine and some of its key features, including parliamentary sovereignty, separation of powers, an independent judiciary, due process, and human rights. It also explores the essential features of an adversarial justice system and the restorative justice principle and concludes with an assessment of the roles of the police, the courts, and the Crown Prosecution Service in the criminal justice system.
