What Is the Process for Appealing a Conviction?

An appeal against a conviction is a formal legal process that allows someone convicted in a criminal court to ask a higher court to review and change the decision. In England and Wales, this process is governed by statute and procedural rules and varies depending on where the original conviction was made. This article explains the process step by step, clarifying rights, time limits, different courts involved, common grounds for appeal, and practical considerations. It is written in clear, accessible language for members of the public, students, and legal practitioners seeking a reliable introductory guide.

What Does It Mean to Appeal a Conviction?

A conviction appeal is a challenge to the finding of guilt in a criminal case. The purpose is not to re‑argue every point of the original trial, but to identify legal errors, procedural irregularities, or other significant issues that could make the conviction unsafe. The court deciding the appeal examines whether the conviction should stand or be overturned.

You cannot appeal simply because you are unhappy with the outcome. You must demonstrate that the original decision was affected by some defect in law, procedure, or fairness.

Which Convictions Can Be Appealed?

Almost all criminal convictions in England and Wales can be challenged, including:

• Convictions after a trial (guilty verdict after hearing evidence)
• Convictions following a guilty plea (subject to limited grounds)
• Convictions in the Magistrates' Court and Crown Court

However, different appeal routes and time limits apply depending on where the conviction was originally made.

Time Limits for Appealing a Conviction

Strict deadlines apply:

• From a Magistrates' Court: Generally, you must lodge an appeal within 15 business days (about 21 days) of the date of sentencing.
• From a Crown Court: You must apply for permission to appeal within 28 days of conviction (or sentencing if later).

If these deadlines are missed, courts may allow an appeal “out of time” if a good reason is provided, but this can be difficult and requires compelling justification.

Step‑by‑Step: Appealing a Magistrates' Court Conviction

1. Notice of Appeal

To appeal a conviction made in a Magistrates' Court, you start by filing a notice of appeal to the Crown Court. You must complete the relevant form and serve it on the Magistrates' Court office and the prosecution (the respondent).

This appeal does not require prior permission in most cases, but the time limit is strict. If you miss the deadline, you must apply for an extension of time and explain the delay.

2. Grounds of Appeal

Your notice should include the grounds of appeal - that is, the legal and factual reasons why the conviction is unsafe. Grounds might include errors in law, misdirection by the magistrates, procedural defects, or misapplication of evidence.

3. Hearing at the Crown Court

When the appeal is accepted, the Crown Court conducts a fresh hearing. This is not a review on paper but a complete re‑hearing of the case with the evidence given again (including witness testimony if required).

A Crown Court judge and at least one magistrate hear the appeal and can:

• Confirm the conviction
• Quash the conviction
• Order a retrial
• Vary the original sentence (if also challenged)

The procedure resembles a new trial.

Step‑by‑Step: Appealing a Crown Court Conviction

1. Apply for Permission to Appeal

Convictions from the Crown Court do not automatically go before an appellate bench. You must first apply for permission to appeal to the Court of Appeal Criminal Division. This is done using Form NG (Notice and Grounds of Appeal), which sets out the reasons for the appeal.

You must send the application within 28 days of conviction (or sentencing if later). Late applications require an explanation.

2. Single Judge Review

A single judge from the Court of Appeal reviews the application to decide if there is an arguable basis for appeal. If permission is refused, you can renew the application (a “renewal”) at the full Court of Appeal.

3. Full Appeal Hearing

If permission is granted, the appeal is heard by a panel of judges in the Court of Appeal. At the hearing:

• Your legal representative presents skeleton arguments
• The prosecution responds
• The court considers legal and factual aspects

The Court of Appeal may:

• Quash the conviction
• Order a retrial
• Substitute a conviction
• Dismiss the appeal if the conviction is not shown to be unsafe

The appeal outcome depends on whether the conviction is found to be unsafe - a statutory standard under the Criminal Appeal Act 1968.

Grounds for Appealing a Conviction

Appeals must be grounded on recognised legal bases. Common grounds include:

• Error of law (incorrect interpretation or application of legal principles)
• Misleading or improper directions to the jury
• Procedural irregularities affecting the fairness of the trial
• New evidence that could not be presented at the original trial (and could have affected the verdict)
• Miscarriage of justice due to material mistakes

Simply disagreeing with how the court assessed evidence is rarely sufficient on its own.

What Happens After the Appeal?

Success

If the appeal succeeds:

• The conviction may be quashed, meaning it is set aside.
• The court may order a retrial if warranted.
• Costs may be awarded in some circumstances.

A quashed conviction does not automatically give rise to compensation, but you may explore compensation schemes if you were wrongfully convicted.

Failure

If the appeal is dismissed:

• The original conviction stands.
• You may have limited rights to apply to higher courts in very narrow circumstances.

Further Options: Criminal Cases Review Commission and Supreme Court

Criminal Cases Review Commission (CCRC)

If all ordinary appeal routes are exhausted and you believe there has been a miscarriage of justice, you can apply to the Criminal Cases Review Commission. The CCRC is an independent body that can investigate and refer a case back to the Court of Appeal if it identifies new evidence or arguments that might render the conviction unsafe.

Supreme Court

An appeal beyond the Court of Appeal to the Supreme Court is rare. It is only permitted where a point of law of general public importance is involved. Permission is required from the Court of Appeal or the Supreme Court itself.

Practical Considerations

• Legal Representation: Appeals are complex and formal. Engaging a solicitor or barrister experienced in criminal appeals significantly improves the chances of properly presenting grounds and complying with procedural rules.
• Time and Cost: Appeal processes can take months or longer and may involve additional legal costs. Some legal aid is available in certain cases.
• Bail Pending Appeal: If you are serving a custodial sentence, you may apply for bail while the appeal is pending, but this is not guaranteed.
• Record and Transcript: Securing a full trial transcript is often essential for preparing grounds of appeal.

Key Takeaways

The process for appealing a conviction in England and Wales depends on the court that convicted you:

• Magistrates' Court convictions are appealed to the Crown Court, normally within 15 business days. The Crown Court re‑hears the case.
• Crown Court convictions are appealed to the Court of Appeal Criminal Division; you must obtain permission within 28 days of the conviction or sentence.
• Appeals challenge legal and procedural errors that render a conviction unsafe.
• If ordinary appeal routes are exhausted, applications to the CCRC or Supreme Court are possible in limited circumstances.
• Strict time limits, formal grounds of appeal, and detailed preparation are essential to the appeal process.

Understanding these steps and deadlines helps clarify how criminal appeals operate and what actions might be considered when a conviction is thought to be unsafe.
