A comprehensive guide to how appeals are reviewed for miscarriage of justice claims in England and Wales, explaining direct appeals, the role of the Criminal Cases Review Commission (CCRC), legal tests, time limits and compensation after quashed convictions.

A miscarriage of justice occurs when an innocent person is convicted or someone receives an unfair sentence. In England and Wales, the legal system has multiple stages and safeguards to review and correct wrongful convictions or sentences. These appeals processes are designed to ensure fairness and maintain public confidence in criminal justice. This article explains how appeals are reviewed for miscarriage of justice claims, detailing the legal framework, procedural rights, the role of key bodies, important tests applied by courts, time limits, practical steps, and related questions.
What Is a Miscarriage of Justice?
A miscarriage of justice happens when a court verdict or sentence is fundamentally flawed, often because of errors of law, new evidence that undermines the original decision, procedural unfairness, or other significant legal failings. The Court of Appeal (Criminal Division) is responsible for reviewing the safety of convictions and sentences. If the court considers a conviction “unsafe,” it can quash it, order a retrial, or substitute a different outcome.
How Criminal Appeals Work in England and Wales
Direct Appeals to the Court of Appeal
After a conviction or sentence in the Crown Court, the defendant has the right to appeal to the Court of Appeal Criminal Division (CACD). Appeals must generally be filed within strict time limits (often 28 days from conviction or sentence), though extensions can occasionally be granted.
The court's statutory duty, as set out under the Criminal Appeal Act 1968, is to allow an appeal if it thinks the conviction is unsafe. This may be because of legal errors at trial, procedural irregularities, or evidence that casts serious doubt on the verdict or sentence.
Direct appeals are typically the first line of challenge against convictions and take into account any errors raised during trial or newly recognised issues that affect the fairness of the original process, such as improper jury directions or unreliable evidence.
The Role of the Criminal Cases Review Commission (CCRC)
An Independent Review Body
Where a defendant's appeal has already been refused or exhausted, and serious issues remain, the Criminal Cases Review Commission (CCRC) offers a second line of review. This statutory body was established under the Criminal Appeal Act 1995 to investigate alleged miscarriages of justice and has the unique power to refer cases back to the appeal courts for reconsideration.
When the CCRC Can Intervene
The CCRC considers applications from anyone who believes they have been wrongly convicted or sentenced - including those who have already lost at appeal. There is no time limit for applying to the CCRC, meaning very old cases can still be examined, although practical challenges such as lost evidence can complicate investigations.
A case is typically referred to the Court of Appeal only if, after investigation, the CCRC concludes there is a real possibility that the conviction or sentence would not be upheld were the appeal to be heard again. This is known as the “real possibility” test under section 13 of the Criminal Appeal Act 1995.
Scope of CCRC Investigations
During its review, the CCRC can access police records, prosecution material, court documents, expert reports and other information using statutory powers. Its independence from the police, prosecution and courts helps ensure impartial investigation, although critics sometimes argue that the test for referral is too restrictive and reliant on predicting how the Court of Appeal will respond.
If the CCRC refers a case to the Court of Appeal, the appeal court then decides whether the conviction is unsafe. The CCRC itself does not have the power to overturn convictions or order compensation - only to refer the case for another appeal.
What Courts Look at When Reviewing Miscarriage of Justice Appeals
When considering whether a conviction is unsafe, appellate courts assess a range of factors:
- Fresh Evidence: Evidence not available at trial, whether newly discovered or not presented previously due to factors outside the defendant's control, may be considered if it could materially affect the verdict or sentence.
- Procedural Errors: Failures in disclosure, legal representation, jury directions or fundamental unfairness can render a conviction unsafe.
- Evidence Reliability: If key evidence used at trial is later shown to be unreliable - for example, flawed forensic results - the Court of Appeal will consider whether this undermines confidence in the original verdict.
- Jury Safety Tests: While the Court of Appeal generally defers to jury findings, it may intervene if it forms a genuine “lurking doubt” about the conviction's safety.
Time Limits and Permission to Appeal
Standard Appeal Deadlines
- Appeals to the Court of Appeal must typically be lodged within 28 days of conviction or sentencing in the Crown Court.
- Appeals from magistrates' courts go first to the Crown Court or, on points of law, to the High Court.
Need for Permission
Most appeals require permission (leave to appeal) from either the lower court or the Court of Appeal itself. This is a threshold step to show that an appeal has a realistic basis before it is fully heard.
Applications to the CCRC
There is no formal deadline to apply to the CCRC for review. However, appellants are advised to apply as soon as possible after exhausting direct appeal rights.
Compensation After Successful Miscarriage of Justice Appeal
If a conviction is quashed on appeal - whether directly or after a CCRC referral - a claimant may be eligible for compensation under the Miscarriage of Justice Compensation Scheme. To qualify, the conviction must be overturned and certain procedural criteria met, such as the timing of the appeal relative to sentencing.
Compensation applications must be supported by official documentation from the appeal outcome and associated court papers.
Practical Steps for a Miscarriage of Justice Claim
- Seek Legal Advice Early: Specialist criminal appeal solicitors can help identify grounds for appeal and navigate complex procedural requirements.
- Gather Evidence: Compile all trial documents, transcripts, expert reports and any new evidence that may affect safety of conviction.
- File Appeal Promptly: Ensure appeal notices and grounds are lodged within statutory time limits.
- Consider CCRC Review: If direct appeal is denied or exhausted, prepare a detailed application to the CCRC, emphasising new evidence or significant legal errors.
- Prepare for Lengthy Processes: CCRC investigations and subsequent appeals can be lengthy and resource‑intensive.
Challenges and Ongoing Debate
Some critics argue that the current legal framework - particularly the “real possibility” test for referrals - can be too restrictive, potentially making it difficult to address all genuine miscarriages of justice. Bodies such as the Law Commission and justice reform organisations have called for reviews of criminal appeals law to ensure fairness and adapt to modern evidence‑based challenges.
High‑profile cases such as the Peter Sullivan wrongful conviction overturned after nearly 40 years demonstrate both the power and limitations of the system in correcting long‑standing miscarriages of justice.
Common Questions About Miscarriage of Justice Appeals
Can anyone apply to the CCRC?
Yes, anyone convicted in England and Wales can apply, including those who have lost their appeal.
What qualifies as new evidence?
New evidence must not have been considered at trial or on appeal and must raise a real possibility that the conviction would be overturned if re‑heard.
Is the CCRC part of the courts?
No. It is independent of the courts, police and prosecution and serves to investigate cases and, if appropriate, refer them back for appeal.
Key Takeaways
Appeals for miscarriage of justice claims in England and Wales are designed to provide fair and robust review mechanisms for individuals wrongly convicted or unfairly sentenced. The process typically begins with a direct appeal to the Court of Appeal, focusing on whether the conviction is unsafe due to errors in law, evidence or procedure. If conventional appeal paths are exhausted, the Criminal Cases Review Commission (CCRC) provides a further independent review route, investigating claims and potentially referring cases back to the Court of Appeal. Success in these processes can lead to quashed convictions, retrials, modified sentences and access to compensation schemes. These safeguards help maintain integrity and public confidence in the criminal justice system.
