A criminal conviction or sentence is not always the last word on a matter. South African law gives a convicted person, and in limited cases the State, the right to ask a higher court to review the decision of the trial court. This process is called an appeal, and it is one of the most important safeguards in our criminal justice system.
An appeal is not a second trial. The appeal court does not hear evidence afresh or call new witnesses. Instead, it looks at the record of what happened in the trial court and asks whether the conviction or sentence is legally sound. That is why the grounds on which you appeal matter so much. A well-grounded appeal identifies a specific error that, if corrected, could change the outcome.
This guide explains the recognised grounds for appeal in criminal cases in South Africa, the leave-to-appeal and petition process, and what to expect at the appeal hearing. It is written for accused persons, their families, and anyone who wants to understand how criminal appeals work under the Criminal Procedure Act 51 of 1977 and the Superior Courts Act 10 of 2013.

What Is a Criminal Appeal in South Africa?
A criminal appeal is the legal process by which a higher court reviews the decision of a lower court in a criminal matter. The most common route is from a Magistrate’s Court to the High Court having jurisdiction, governed by the Criminal Procedure Act 51 of 1977. Appeals from the High Court to the Supreme Court of Appeal, and from there to the Constitutional Court, are governed by the Superior Courts Act 10 of 2013 and the Constitution.
The appeal court does not reconsider the case as if it were the trial court. It works from the record, the written judgment, and the heads of argument filed by both sides. Oral argument may be heard, but the focus during appellate review is on whether the trial court erred in a way that justifies setting aside or changing the outcome.
The Main Grounds for Appeal in Criminal Cases
South African courts recognise four broad categories of ground on which a criminal conviction or sentence may be challenged. Each one is addressed in detail below.
- Misdirection on law or fact. The trial court wrongly interpreted the law, misapprehended the evidence, or made a finding no reasonable court could make on the facts.
- Procedural irregularity. The trial did not follow the prescribed procedure, affecting the fairness of the proceedings.
- Verdict unreasonable on the evidence. Even if each step was technically correct, the conviction is not supported by the evidence as a whole.
- Sentence. The sentence is disturbingly inappropriate, either too severe for the accused or too lenient for the State.
Misdirection on Law or Fact
Misdirection is the most common ground of appeal. A misdirection on law happens when the trial court interprets a statute incorrectly, applies the wrong legal test, or wrongly admits or excludes evidence. A misdirection on fact happens when the court misapprehends the evidence, ignores material evidence, or makes a factual finding that the record does not support.
The leading principle was set out in R v Dhlumayo 1948 (2) SA 677 (A). On questions of law, the appeal court has a wide discretion to interfere because it is in as good a position as the trial court to decide the law. On questions of fact, the appeal court will be slower to interfere, because the trial court saw and heard the witnesses. Even so, where the trial court’s factual findings are not reasonably supported by the evidence, the appeal court will set them aside.
Procedural Irregularity
A procedural irregularity is a failure to follow the rules that govern a criminal trial. Not every irregularity justifies setting aside a conviction. The test, drawn from cases such as S v Sikunyana 1978 (3) SA 551 (A), is whether the irregularity caused a failure of justice. If the accused’s right to a fair trial, protected by section 35(3) of the Constitution, was breached in a way that affected the outcome, the conviction will usually be set aside.
Examples include the wrongful admission of inadmissible evidence, failure to explain the right to silence or the right to legal representation, a refusal to grant an adjournment that prevented the accused from properly presenting a defence, or bias on the part of the presiding officer.
Verdict Unreasonable on the Evidence
This is the “reasonable possibility” test. Even where the trial court committed no identifiable error of law and no obvious procedural irregularity, the conviction can still be set aside if the verdict is unreasonable on the evidence. In S v Shackell 2001 (4) SA 1 (SCA) the Supreme Court of Appeal confirmed that an appeal court will interfere only if, having considered the evidence as a whole, it concludes that there is a reasonable possibility that the trial court’s finding is wrong, or that the verdict is one that no reasonable court could have reached.
This ground is deceptively narrow. The appeal court does not substitute its own view of the facts. It asks whether a reasonable court decision, acting fairly on the evidence, could have convicted. If the answer is yes, the conviction stands, even if the appeal court might itself have reached a different conclusion.
Sentence Appeals: Too Severe or Too Lenient
An accused may appeal against sentence even where the conviction is not challenged, and the State may, in limited circumstances, appeal against a sentence it considers too lenient. The principles were comprehensively set out by the Supreme Court of Appeal in S v Malgas 2001 (1) SA 1222 (SCA).
The appeal court will not interfere with the trial court’s sentencing discretion merely because it would have imposed a different sentence. It will interfere only where the trial court committed a misdirection, such as over-emphasising aggravating factors, ignoring mitigating factors, or failing to apply the correct legal principles. The sentence must be one that is, in the words of S v Malgas, “disturbingly inappropriate” before the appeal court will alter it.
Leave to Appeal and the Petition Stage
Not every conviction can be appealed as of right. Most criminal appeals require leave (permission) of the court. For appeals from the Magistrate’s Court to the High Court, section 309B of the Criminal Procedure Act 51 of 1977, introduced by the Judicial Matters Second Amendment Act 55 of 2003, requires the appellant to obtain leave before the appeal can proceed. Where the accused pleaded guilty, separate provisions in section 316 of the Criminal Procedure Act apply.
For appeals from the High Court (sitting as a court of first instance in serious matters) to the Supreme Court of Appeal, section 62(1) of the Superior Courts Act 10 of 2013 applies. Following the 2014 amendments, the test is higher than the old “reasonable prospect of success” test. The appellant must show either that there is a reasonable prospect that another court would come to a different conclusion, or that there is some other compelling reason why the appeal should be heard.
If the judge in the court a quo refuses leave, the aggrieved party may petition the decision. In the High Court, the petition is directed to the Supreme Court of Appeal and considered by a panel of judges. Petitions are decided on the papers and must be lodged within strict time limits, usually 21 days from the refusal. Strong grounds, properly formulated, are essential at this stage because most failed petitions end the matter.
The Appeal Hearing: What Happens Next
Once leave is granted, the matter is enrolled for hearing. The appellant files heads of argument setting out the grounds of appeal and the legal authorities relied on. The respondent files answering heads. On the day of the hearing, counsel for both sides present oral argument before a bench, typically two or three judges in the High Court and five in the Supreme Court of Appeal.
The possible outcomes of an appeal against conviction include the conviction being confirmed, set aside and replaced with an acquittal, or set aside and remitted to the trial court for a retrial. For an appeal against sentence, the appeal court may confirm the sentence, reduce it, or, where the State appeals, increase it. The appeal court’s reasons form part of the developing body of South African criminal law.
Time limits are strict. Notice of appeal must usually be filed within 14 days of the sentence in the Magistrate’s Court, and similar periods apply in the High Court. Missing the deadline can extinguish the right to appeal, which is why anyone considering an appeal should take advice immediately after conviction and sentence.
Frequently Asked Questions
What are the grounds for appeal in a criminal case in South Africa?
The recognised grounds are misdirection on law or fact by the trial court, a procedural irregularity that caused a failure of justice, a verdict that is unreasonable on the evidence under the reasonable possibility test, and a sentence that is disturbingly inappropriate. Each ground must be identified with reference to the trial record.
Do I need leave to appeal in a criminal matter?
In most criminal appeals yes. Section 309B of the Criminal Procedure Act 51 of 1977 requires leave for appeals from the Magistrate’s Court to the High Court, and section 316 applies where the accused pleaded guilty. For appeals from the High Court to the Supreme Court of Appeal, section 62 of the Superior Courts Act 10 of 2013 requires the appellant to show a reasonable prospect that another court would come to a different conclusion or some other compelling reason.
What happens if leave to appeal is refused?
If the judge in the court a quo refuses leave, the aggrieved party may petition the refusal. The petition is decided on the papers by a panel of judges and must be lodged within strict time limits, usually 21 days. A weak petition ends the matter, so the grounds must be properly formulated.
What are the possible outcomes of a criminal appeal?
For an appeal against conviction the court may confirm the conviction, set it aside and substitute an acquittal, or set it aside and order a retrial before a fresh court. For an appeal against sentence the court may confirm, reduce, or in a State appeal increase the sentence.
Can the State appeal a criminal case in South Africa?
Yes, but only in limited circumstances. The State may appeal against an acquittal on a question of law with the required leave, and may appeal against a sentence it considers too lenient. The same leave-to-appeal thresholds under the Criminal Procedure Act 51 of 1977 and the Superior Courts Act 10 of 2013 apply.
