The Crown Prosecution Service (CPS)

The Crown Prosecution Service (CPS) is the principal prosecuting authority in England and Wales. This topic explores how the CPS works independently of the police to decide which cases should proceed to court. Students learn to apply the 'Full Code Test,' which consists of the Evidential Stage and the Public Interest Stage. This is a critical skill for WJEC AC 2.1, as it requires students to think like legal professionals.

Simulation Game: The Charging Decision

Provide groups with three case files containing witness statements and forensic reports. Students must apply the Full Code Test and write a brief justification for whether to charge, caution, or drop the case.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • The police decide who gets prosecuted in court.

    While the police investigate and suggest charges, the CPS makes the final decision for all but the most minor offences. Simulation exercises where students act as CPS lawyers help clarify this shift in power.

  • If there is enough evidence, the CPS must always prosecute.

    Even with strong evidence, a case must pass the Public Interest Stage. If prosecuting would be disproportionate or harmful to the victim, the CPS may decline. Think-pair-share activities on 'mercy' cases help surface this distinction.
