Abstract
This chapter discusses the principles and structure of criminal law and evaluates the criminal justice system in the light of statistics and public perception and the context in which the criminal law operates. It begins with a discussion of the definition of crime and criminalisation and explains theories of criminal law, such as the harm principle, moralism, and feminism. Problem question technique and IRAC are discussed in this chapter. The burden and standard of proof in criminal proceedings and the classification of crimes and the courts are discussed. Finally, the chapter explores miscarriages of justice, punishment, and access to justice.
