When and How You Can Challenge a Criminal Sentence

Receiving a criminal conviction or a sentence that feels unjust is a disorienting and dispiriting experience. In that moment, many people feel that the outcome is fixed – that the court has spoken and nothing more can be done. That perception is understandable but often incorrect. The NSW criminal justice system includes formal mechanisms for reviewing decisions, and a surprising number of outcomes that seem final at the time of sentencing are genuinely capable of being changed through the appeals process.

Understanding your right to appeal – including the strict time limits that apply – is one of the most important things you can know in the aftermath of an unfavourable court outcome. At Essere – The Defenders, we assist clients with appeals at every level of the NSW court system, and the consistent pattern we observe is that the people who seek advice quickly have the most options available to them.

What Types of Decisions Can Be Appealed?

The NSW appeals framework allows a range of court decisions to be challenged. The most common grounds pursued by defendants include the sentence imposed – where the defendant believes the sentence is excessive, fails to properly account for relevant mitigating circumstances, or reflects a legal error in the sentencing exercise. A finding of guilt following a defended hearing or trial can also be challenged where there was a legal error in the conduct of the proceedings, a misdirection to a jury, or a factual finding that was not properly open on the evidence.

Decisions made during proceedings that affected the outcome – evidentiary rulings, procedural decisions, or failures of process – can in some circumstances form grounds for appeal even if they were not specifically challenged at the time they were made. And in serious criminal matters, applications based on fresh evidence – evidence that was not available and could not reasonably have been obtained at the time of the original hearing – can provide a basis for a conviction to be reconsidered.

The Court Hierarchy and Where Appeals Are Heard

Where your appeal is heard depends on which court made the original decision. Decisions of the Local Court – where the majority of criminal matters in NSW are heard and determined – are appealed to the District Court, which conducts what is known as a rehearing. At a rehearing, the matter is considered again on its merits rather than simply reviewed for legal error, which means new evidence can be called and both prosecution and defence have an opportunity to present their cases again. District Court decisions are reviewed by the NSW Court of Criminal Appeal, which primarily considers questions of law. For matters of significant constitutional or legal principle, final appeals may be made to the High Court of Australia.

Time Limits: The Most Important Thing You Need to Know

This is the element of the appeals process that most people underestimate, and it is the one that causes the most preventable loss of rights. In NSW, an appeal from the Local Court to the District Court must generally be lodged within 28 days of the date of conviction or sentence. This is a strict deadline. Applications to lodge out of time require satisfying the court that there was good reason for the delay – a threshold that becomes progressively harder to meet the longer time passes.

Twenty-eight days passes very quickly when you are dealing with the aftermath of a criminal outcome. The practical implication is clear: if you have received a conviction or sentence you believe is wrong, the most important thing you can do is seek legal advice immediately – not in a few weeks, and not when it feels more convenient. The earlier a lawyer can review your case, the better positioned you are to explore all available options.

What Makes an Appeal Succeed?

An appeal is not simply an opportunity to re-argue the same facts before a different judicial officer and hope for a different result. Appellate courts review decisions against specific legal criteria, and a successful appeal requires the identification and demonstration of specific grounds – the articulation of what was wrong with the original decision, why it meets the legal threshold for appellate intervention, and what different outcome should follow.

Common grounds that courts accept include errors of law in how the trial or sentencing was conducted; manifest excessiveness in the sentence imposed, meaning the sentence was clearly outside the range that a proper exercise of sentencing discretion would support; factual findings that were not reasonably open on the evidence before the court; procedural unfairness or denial of natural justice; and inadequate representation that fell below the standard required to constitute a fair trial. Establishing these grounds requires detailed knowledge of the law of criminal appeals and careful analysis of the original proceedings.

The Real Cost of Not Appealing When You Should

Accepting a conviction or sentence that has genuine grounds to be challenged – because you did not know you could appeal, because you were not advised of the possibility, or because it seemed too difficult – is a decision with real and lasting consequences. A criminal conviction affects employment, professional licensing, international travel, and many other aspects of life in ways that accumulate over time. An unjust or excessive sentence means time taken from you that cannot be returned. The decision not to explore available options is itself a consequential choice.
