ThinkRankUnderstanding Our Criminal Justice System
A criminal justice system investigates alleged offences, protects rights, presents evidence, and decides guilt through a fair trial. Police, prosecutors, defence lawyers, magistrates, judges, prisons, victims, and accused persons have different roles. Presumption of innocence and due process protect everyone from arbitrary punishment.

- •Explain fair trial
- •Explain justice includes safeguards
Key Concepts
Investigation and evidence
Police investigate, collect evidence, record statements, and follow legal procedures; investigation is not the same as proof of guilt.
Fair trial
The accused has rights to know the charge, obtain legal representation, challenge evidence, and be judged by an impartial court.
Justice includes safeguards
Arrest rules, bail, legal aid, judicial oversight, and the presumption of innocence limit misuse of state power.
Terminology
Historical Insight
Legal aid
A person who cannot afford a lawyer should be able to receive legal assistance so poverty does not decide the quality of defence.
Witness evidence
A court examines the reliability and relevance of evidence rather than treating an accusation as a conviction.
