Miscarriages of Justice

Miscarriages of Justice examines the failures of the criminal justice system that lead to wrongful convictions or the acquittal of the guilty. Students analyse the causes of these failures, such as police misconduct, unreliable forensic evidence, false confessions, and witness error. The topic also covers the appeals process and the role of the Criminal Cases Review Commission (CCRC) in investigating potential errors. This aligns with WJEC AC3.1 and AC3.2, requiring students to examine information for validity and draw conclusions.

Activity 01

Inquiry Circle50 min · Small Groups

Inquiry Circle: Case File Cold Case

Provide groups with a summary of a famous miscarriage of justice. They must act as the CCRC, identifying three specific 'points of failure' (e.g., hidden evidence or coerced confession) that justify a new appeal.

Formal Debate: The Right to Appeal

Divide the class. One side argues that the appeals process should be easier to access to prevent wrongful convictions. The other side argues that too many appeals undermine the finality of the law and distress victims. Both must use criminological terms.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Miscarriages of justice only happened in the 'old days' before DNA.

    While DNA has helped, miscarriages of justice still happen due to human error, new types of digital evidence, or procedural mistakes. The 'Case File Cold Case' activity helps students see that the *reasons* for failure are often systemic, not just technological.

  • If someone is found 'not guilty' on appeal, it means they are definitely innocent.

    A successful appeal often means the original conviction was 'unsafe' (procedurally flawed), not necessarily that the person is innocent. Understanding the legal term 'unsafe conviction' is a key distinction for students to make in their writing.
