A detailed explanation of how wrongful conviction appeals are reviewed in England and Wales, covering the role of the Court of Appeal, the Criminal Cases Review Commission (CCRC), appeal grounds, the CCRC review process, outcomes after referral, compensation claims for quashed convictions, and practical guidance for those seeking to challenge unsafe convictions.

Wrongful convictions are among the most serious miscarriages of justice. In England and Wales, there is no simple mechanism to rewrite history, but the legal system does provide structured procedures that allow convictions to be challenged and, in appropriate cases, overturned. This article explains how appeals are reviewed in wrongful conviction claims, who can initiate them, how the process works, what bodies are involved, and what options exist if an appeal fails. It also addresses compensation after a conviction is quashed and practical considerations for people navigating these procedures.
What Is a Wrongful Conviction?
A wrongful conviction occurs when a person is found guilty of a criminal offence they did not commit, whether because of flawed evidence, procedural error, misinterpretation of law, or other serious defects in the trial process. The key legal principle underpinning all appeals is that a conviction must be safe and just; if it isn't, it may be overturned on appeal.
Grounds for Appeal After Conviction
If a person has been convicted in a criminal court in England and Wales, they may be able to lodge an appeal. Successful appeals generally require legitimate legal grounds, such as:
- Errors of law: The trial judge may have misdirected the jury or applied the law incorrectly.
- Procedural irregularities: Fundamental procedural failures could include unfair jury selection, inadmissible evidence wrongly admitted, or serious disclosure failures.
- New evidence: Material evidence that was not available at trial and could not reasonably have been presented at that time.
- Unfair trial: Any other factor that so undermines confidence in the verdict that it would be unsafe to uphold it.
These are examples; successful appeals hinge on demonstrating that the original conviction was unsound in law or fact. The appeal process is not an automatic retrial; it is a review of the original decision.
The Court of Appeal: First Line of Defence
In England and Wales, appeals against conviction are usually heard by the Court of Appeal (Criminal Division). This court is the principal appellate body for criminal cases, and it has the power to:
- Quash convictions it considers unsafe.
- Order retrials in some circumstances.
- Alter sentences if a sentence is disproportionate or unlawful.
To bring an appeal, the convicted person typically must first obtain leave (permission) to appeal. This may be granted at the trial court or by the Court of Appeal itself. The court scrutinises the grounds of appeal and, where appropriate, permits a full hearing. Returns to the Court of Appeal after conviction are time‑limited and subject to strict procedural requirements. For example, applications must generally be made within defined periods from the date of conviction or sentence.
If an appeal is unsuccessful, or if no appeal rights remain, another avenue may be available.
The Criminal Cases Review Commission (CCRC)
For many convicted individuals who have already exhausted their appeal rights, the statutory body responsible for reviewing potential miscarriages of justice is the Criminal Cases Review Commission (CCRC). Established under the Criminal Appeal Act 1995, the CCRC is independent of the police, prosecution and courts. It has the unique power to investigate suspected wrongful convictions and, critically, refer cases back to the Court of Appeal for a fresh hearing.
When Can the CCRC Consider a Case?
The Commission reviews cases if:
- The person has already appealed and lost, or
- There are exceptional circumstances where an appeal was not pursued or possible.
There is no statutory time limit for applying to the CCRC. Individuals can seek a review decades after conviction if new evidence or arguments emerge.
What Does the CCRC Look For?
The CCRC examines applications for evidence or legal issues that might make a conviction unsafe. This could include:
- New evidence or arguments not raised at trial or on appeal.
- Errors in forensic, scientific or witness evidence.
- Evolving legal principles that affect the fairness of the original trial.
If the Commission believes there is a real possibility that the appeal court would quash the conviction or modify a sentence, it will refer the case back for a fresh appeal.
The CCRC Process
- Initial Screening: The Commission checks eligibility and whether it has legal powers to investigate.
- Investigation: Case papers, trial records, previous appeal materials and any new material are gathered.
- Decision: If investigators and Commissioners agree there is merit, the CCRC refers the case to the Court of Appeal.
In practice, most applications do not result in referrals, and the threshold for a referral is high. If the CCRC declines to refer a case, an applicant may be able to challenge that decision by judicial review.
What Happens After a Referral?
Once the CCRC refers a case, the Court of Appeal reviews it afresh. The referral triggers a new hearing in which both defence and the prosecution present arguments. The court's task is to decide whether the conviction or sentence is unsafe. A successful appeal will typically result in the conviction being quashed. A sentence may also be reduced or otherwise altered.
Compensation After a Conviction Is Quashed
If a conviction is overturned on a successful appeal, including following a CCRC referral, an individual in England and Wales may be able to claim compensation for miscarriage of justice. The GOV.UK compensation scheme provides that:
- Claims can be made if the conviction was quashed and was submitted after defined time frames.
- Applications go through the Miscarriages of Justice Applications Service.
This compensation is distinct from damages claims in civil court and has its own legal criteria. Claimants must prove their innocence beyond reasonable doubt under current rules, which campaigners and legal bodies have criticised as excessively stringent.
Practical Considerations
- Legal Representation: Appeals and CCRC applications are legally complex. Many applicants instruct solicitors or specialist advocacy groups.
- Evidence Gathering: New evidence or robust legal argumentation is essential to succeed in review stages.
- Support Services: Organisations such as the Miscarriages of Justice Support Service provide practical assistance on steps post-release and during claims processes.
Key Takeaways
In England and Wales, wrongful conviction appeals are reviewed through a combination of judicial and administrative pathways:
- The Court of Appeal is the main forum for challenging convictions on legal and factual grounds.
- The Criminal Cases Review Commission (CCRC) provides a crucial safety net for cases where appeal rights have been exhausted but fresh evidence or issues suggest a conviction may be unsafe.
- A successful appeal can lead to a quashed conviction and opens the door to compensation under the statutory scheme.
These systems aim to balance finality in criminal justice with fairness and protection against miscarriages of justice. They are intricate, and while powerful, they require careful navigation of legal standards and procedures.
