7. The Criminal Justice System
Each Concentrate revision guide is packed with essential information, key cases, revision tips, exam Q&As, and more. This chapter examines the criminal justice system (CJS). The CJS is built upon procedural, evidential, and substantive foundations. These foundations dictate its direction and progression. A case will always begin with an investigation by the police or some other investigatory body. An individual may then be charged with an offence where he/she is provided with the option of pleading guilty or not guilty. Trial may follow. Where the defendant's case will be tried depends on the type of offence in question and, in some cases, the decision of the defendant. A convicted person may appeal against either conviction or sentence for which the defendant will be required to prove why they either should not have been convicted, or why their sentence should be reduced.
