Learn how appeals are heard in England and Wales for cases involving severe aggravating factors. This guide covers criminal appeal routes, time limits, grounds for challenging sentences, how aggravating factors are treated on appeal, and mechanisms like the unduly lenient sentence scheme.

When a person is convicted of a criminal offence in England and Wales, the sentencing judge will consider aggravating factors that make the offence more serious. These factors can influence the length or severity of the sentence. If a defendant believes that an appellate court has not properly dealt with those aggravating factors, or that the sentence is excessive or unduly lenient, there are established routes to challenge the decision. This article explains how appeals are handled in such cases, the courts involved, applicable timings, key legal principles, and practical steps for affected parties.
What Are Aggravating Factors and Why They Matter
In sentencing, courts are required to assess the seriousness of an offence by identifying relevant factors that increase culpability or harm. An aggravating factor is anything that makes the offence more serious than an ordinary example of that offence. Common examples include:
- The offence was committed while on bail for another offence.
- The offender has relevant previous convictions.
- Hostility based on characteristics such as race, religion, disability or sexual orientation.
- Abuse of a position of trust.
- Multiple victims or especially serious harm caused.
Aggravating factors directly affect sentencing decisions under the Sentencing Council's guidelines and must be balanced against mitigating factors when judges determine an appropriate sentence.
Grounds for Appeal in Cases with Severe Aggravating Factors
An appeal is not a re‑trial. In criminal appeals, the focus is on errors in law or principle, and whether the sentence was manifestly excessive or unduly lenient given all circumstances, including aggravating factors.
1. Manifestly Excessive Sentences
A defendant may appeal against sentence if they believe the decision was manifestly excessive. This occurs when the sentence exceeded the proper range that a sentencing judge could reasonably consider, having properly applied the sentencing guidelines and weighed aggravating against mitigating factors.
Appellants commonly argue that:
- The court applied too high a starting point for sentencing.
- Aggravating factors were given disproportionate weight.
- The judge misclassified the severity category of the offence.
- The balance between aggravating and mitigating factors was improper.
2. Wrong in Law or Procedural Errors
An appellant may also complain that the sentencing judge misapplied the law or failed to adhere to procedural requirements (for example, failing to give adequate reasons for the sentence). Such errors can include not properly explaining how aggravating factors influenced the sentence.
Appeal Routes and Courts
The route for appeal depends on where the sentence was imposed and the specific issue under challenge.
✧ Appeals from the Magistrates' Court
If convicted and sentenced in the magistrates' court, a defendant generally has an automatic right of appeal to the Crown Court against conviction or sentence. The Crown Court re‑hears both the law and facts (on appeals against conviction) or reconsiders the sentencing exercise itself.
✧ Appeals from the Crown Court
For cases dealt with in the Crown Court, an appellant must apply for permission to appeal to the Court of Appeal Criminal Division under the Criminal Appeal Act 1968. Permission is typically required for both conviction and sentence appeals, and must be applied for within statutory time limits.
The Court of Appeal
The Court of Appeal in England and Wales is the principal appellate body for criminal appeals. It hears cases on conviction or sentence from the Crown Court and evaluates whether the original decision was unsafe (for convictions) or unjust (for sentences), including whether aggravating factors were properly accounted for.
Time Limits for Filing Appeals
Strict time limits apply in criminal appeals:
- From the Magistrates' Court: Appeals must usually be made within 21 days of conviction or sentence.
- From the Crown Court: Appeals must be lodged within 28 days of conviction for conviction appeals or within 28 days of sentencing for sentence appeals.
If an appellant misses these deadlines, they may apply for permission to appeal out of time, but must provide credible reasons why the standard time limit could not be met.
Special Appeals: Unduly Lenient Sentences
In serious criminal cases, the Unduly Lenient Sentence Scheme allows members of the public, victims or Crown officials to ask the Attorney General's Office to review a sentence and decide whether it should be referred to the Court of Appeal for being unduly lenient.
To qualify:
- The case must involve serious offences triable on indictment.
- A referral must be requested within 28 days of the sentencing.
- If the Court of Appeal agrees the sentence is unduly lenient and outside the range which a reasonable sentencer could consider appropriate, it may increase the sentence.
This mechanism ensures that severe aggravating factors which may have been undervalued in the original sentencing can be re‑examined through public and prosecutorial channels.
What Happens at the Appeal Hearing
Once an appeal is permitted:
- Skeleton arguments are exchanged between the appellant and the Crown Prosecution Service, setting out points of law and grounds for challenge.
- The Court of Appeal will hear legal argument and review transcripts and sentencing remarks.
- For sentence appeals, the court assesses whether the sentence was wrong in law or manifestly excessive, considering how aggravating factors were applied.
The court may:
- Uphold the original sentence.
- Reduce the sentence if it finds clear error or disproportion.
- Increase the sentence in unduly lenient reviews.
- Quash a conviction if unsafe.
Practical Guidance for Appeals Involving Aggravating Factors
Seek Early Legal Advice
Preparing an appeal requires gathering transcripts, analysing sentencing remarks, and identifying legal errors relating to aggravating factors. Early advice from a solicitor or experienced appellate counsel improves prospects of identifying valid grounds.
Certify the Grounds Clearly
Grounds of appeal must clearly articulate why the sentence was unjust, whether due to misapplication of aggravating factors, undue severity, or failure to balance mitigating circumstances.
Anticipate Possible Outcomes
An appeal may result in:
- A reduction of the sentence.
- Confirmation of a proper sentence.
- An increase in sentence if the Attorney General's scheme finds the original too lenient.
Key Takeaways
In England and Wales, appeals in cases with severe aggravating factors are handled through established criminal appeal routes:
- From magistrates' courts to Crown Court for rehearings.
- From Crown Court to the Court of Appeal under the Criminal Appeal Act 1968.
- Through public or official referral for review of unduly lenient sentences within strict time limits.
An appeal challenges the legal correctness or appropriateness of the original decision, rather than simply disagreeing with it. Success depends on convincing the appellate court that the original sentencing misapplied the law or treated aggravating factors improperly.
