What is a conviction appeal in Victoria?
A conviction appeal is a challenge to a finding of guilt, asking a higher court to overturn the conviction. It is different from a sentence appeal, which accepts the conviction but challenges the penalty, and the two can sometimes be run together. An appeal is not a chance to simply re-argue the case for its own sake, but a formal process with defined pathways, grounds, and strict time limits.
Understanding where an appeal fits in the wider process helps, and our guide on what happens after being charged sets out the journey that leads to a conviction in the first place. Once a conviction is entered, the appeal system is how the law allows it to be tested.
Which court do you appeal to?
That depends entirely on which court convicted you, and the two pathways are very different. A conviction in the Magistrates’ Court is appealed to the County Court, while a conviction in the County or Supreme Court is appealed to the Court of Appeal. The table below sets out the key differences.
| Feature | Magistrates’ Court conviction | County / Supreme Court conviction |
| Appeal to | County Court | Court of Appeal |
| Type of appeal | Full rehearing (de novo) | Review on grounds, not a rehearing |
| Leave required? | No | Yes, leave to appeal is required |
| Time limit | 28 days from sentence | 28 days from sentence |
| Sentence risk | Can be increased, with a warning | Considered on the grounds raised |
The distinction matters because it changes almost everything about how the appeal runs, from whether the whole case is heard again to what you must prove. This is closely related to the difference between conviction and sentence appeals, which is worth understanding before deciding what to challenge.
How do you appeal a Magistrates’ Court conviction?
You appeal to the County Court, and the appeal is a full rehearing of the whole case. As Victoria Legal Aid explains, a County Court judge listens to the entire case again, without a jury, and the witnesses give their evidence again. This makes it a genuine second chance rather than a narrow review of what the magistrate did.
There is an important catch on sentence, though. Because the County Court hears the matter afresh, it can impose a lighter, the same, or a more severe sentence than the magistrate did, although the judge must warn you if they are considering a heavier penalty, giving you a chance to withdraw the appeal. The practical detail of this pathway is covered in our guide on how to appeal a Magistrates’ Court decision.
How do you appeal a County or Supreme Court conviction?
You appeal to the Court of Appeal, and, unlike the Magistrates’ pathway, you must first be granted leave to appeal. The Supreme Court of Victoria explains that in most cases you need the court’s permission for the appeal to be heard, which means persuading the court that your grounds are reasonably arguable.
This appeal is not a rehearing. Instead of hearing the witnesses again, the Court of Appeal examines whether something went wrong at the trial, based on the grounds you raise, the trial record, and legal argument. That makes the identification of proper grounds, and the quality of the written case, absolutely central to whether an appeal succeeds.
What are the grounds for a conviction appeal?
A conviction appeal must be built on recognised grounds, not simply a wish for a different result. Under the Criminal Procedure Act 2009, the Court of Appeal must allow a conviction appeal in three situations: where the verdict is unreasonable or cannot be supported having regard to the evidence, where an error or irregularity in the trial has caused a substantial miscarriage of justice, or where for any other reason there has been a substantial miscarriage of justice.
These grounds are demanding, and identifying which one genuinely applies is expert work. A dislike of the outcome is not a ground, but a real error in the way the trial was run, a misdirection to the jury, or a verdict that the evidence simply could not support may be. Getting the grounds right is the single most important part of a Court of Appeal matter.
What is the time limit, and can you appeal after pleading guilty?
The time limit is short and strict: 28 days from the date of sentence, for both appeal pathways. If you miss that window, you can still apply, but you must seek an extension of time and explain the delay, which the court is not obliged to grant. This is why acting quickly, and getting advice within days rather than weeks, matters so much.
Appealing a conviction after pleading guilty is far harder, but not impossible in limited circumstances, such as where the plea was not properly informed or was entered under some disadvantage. It is a narrow path, and closely connected to the question of whether you can change a plea after pleading guilty, which is itself a demanding process. Anyone in this position should get advice quickly and specifically.
What should you do if you want to appeal?
Act fast and get advice, because the merits, the pathway, and the deadline all need to be assessed at once. An appeal is not automatically the right move in every case, and part of good advice is an honest assessment of the prospects, since a weak appeal can carry risks, including on sentence. You can see how we approach criminal appeals and judicial review, which is a specialised area of practice.
The practical steps depend on the pathway, but they always begin with a clear-eyed review of what went wrong and whether it fits a recognised ground. For a Magistrates’ matter, the appeal is heard afresh in the County Court, while a higher-court conviction goes to the Court of Appeal on defined grounds. Either way, the earlier the review begins, the more can be done within the time available.
