If you have been convicted of a crime in Western Australia, it’s important to understand your rights to appeal and your chances of having the conviction overturned.
The following outlines the complex process of appealing a criminal conviction in WA, including common grounds for appeal, possible outcomes and the importance of legal representation.
What Is A Criminal Appeal?
A criminal appeal is a review of a decision made in a lower court on the basis of the conviction, the sentence given or both.
An appeal against conviction attempts to challenge the guilty verdict at trial, whilst an appeal against sentence is either arguing that the penalty imposed was manifestly excessive (if appealed by the defence) or inadequate (if appealed by the prosecution).
The primary statute governing criminal appeals in Western Australia is the Criminal Appeals Act 2004 (WA), which outlines two main pathways to appeal a criminal conviction:
- If the conviction occurred in the Magistrates Court, the appeal is generally brought before a single Judge of the Supreme Court under Part 2 of the Act.
- If the conviction followed a trial in the District Court or Supreme Court, the appeal is brought to the Court of Appeal under Part 3 of the Act.
The Act sets out both the grounds upon which an appeal may be brought and the powers available to the appellate court if the appeal succeeds.
Where a person is convicted in the Magistrates Court, section 13 of the Act provides that the a single Judge of the Supreme Court determines the appeal. This is not the case where the appeal comes from the District Court. In this case a coram of three Judges on the Court of Appeal determine the appeal. In both cases the appeal is conducted as a review process focused on whether there is legal error, unreasonable verdicts or miscarriages of justice.
Common Grounds for Appealing A Conviction
There are several well-established grounds for appealing a conviction, including error of law, unreasonable or unsupported verdicts, miscarriage of justice, and the emergence of fresh and compelling evidence.
Each ground reflects a distinct way in which a conviction may be shown to be unsafe or legally flawed, with a criminal lawyer relying heavily on the evidence presented at the original trial.
Error of Law
A common ground of appeal is that the trial judge made an error of law. This can include:
- Incorrect directions to the jury on the elements;
- Misinterpretation of the law; or
- Misapplication of evidentiary rules.
For example, if a jury was incorrectly directed on the meaning of self-defence for a charge of grievous bodily harm, that may constitute a misdirection on a question of law. Similarly, if evidence was admitted in breach of evidentiary rules and that ruling materially affected the verdict, an appeal may succeed on this ground.
Not every legal error results in a conviction being overturned. The court may still dismiss the appeal if it considers that no substantial miscarriage of justice has actually occurred despite the error.
Unreasonable or Unsupported Verdicts
A conviction may also be set aside if the verdict is unreasonable or cannot be supported having regard to the evidence.
This ground was explained in M v The Queen (1994) 181 CLR 487 as requiring the appellate court to conduct its own review of the evidence and determine whether it was open to the jury to be satisfied of guilt beyond reasonable doubt. The question is not whether the appellate court would have reached the same verdict, but whether, on the whole of the evidence, there remains a reasonable doubt.
This ground is difficult to establish, as appellate courts are cautious about interfering with verdicts unless the evidence is demonstrably inconsistent or implausible.
Miscarriage of Justice
An appellate court may also overturn a conviction if there has been a general miscarriage of justice, reflecting some fundamental unfairness in the original trial. Examples may include:
- Failure to disclose exculpatory material;
- Improper prosecutorial conduct;
- Jury irregularity; or
- Denial of procedural fairness.
This broad ground captures situations where the integrity of the trial process has been compromised by a significant departure from proper trial processes, so much so that an appeal is necessary.
Fresh and Compelling Evidence
A relatively new provision under section 35D of the Act allows for an appeal if fresh and compelling evidence has been uncovered which indicates a miscarriage of justice has occurred.
Evidence is “fresh” if it could not have been adduced at trial despite reasonable diligence, or if it was not adduced due to the incompetence or negligence of the offender’s lawyer. Evidence is “compelling” if it is highly probative in light of the issues disputed at trial.
The threshold for fresh and compelling evidence is high and heavily fact-dependent, with the appellate court likely to be reluctant to overturn a conviction unless newly discovered evidence drastically changes the nature of the original trial.
Time Limits for Appeals in WA
Appeals in WA are subject to strict time limits in which an appeal must be filed.
An appeal against a Magistrates Court decision must be made within 28 days of the date of the decision or sentencing (whichever is later). The court can extend time, however the applicant must provide a satisfactory explanation for delay and demonstrate that the proposed appeal has merit
Further, an appeal against a decision of the District Court or Supreme Court must be made within 21 days of the date of the decision or sentencing (whichever is later). If you are late lodging your appeal, you will need to ask the Supreme Court to let you lodge your appeal outside of time.
Possible Outcomes Of An Appeal
There are a number of possible outcomes following a successful appeal against conviction. If a court allows the appeal, it may:
- Quash the conviction and direct a judgment of acquittal;
- Order a new trial;
- Substitute a conviction for another offence that was open on the indictment.
The decision on whether a new trial should be ordered will largely depend on the nature of the error identified and whether, absent that error, there remains admissible evidence capable of supporting a conviction.
The court may also take into account the practical consequences of ordering a further trial, including the passage of time since the alleged offending, the availability and reliability of witnesses, and the potential hardship to both the accused and any complainant or civilian witnesses.
Why Appeals Are Complex
An appeal can often be more complex than the original trial, relying heavily on legal arguments and forensic dissection of transcripts and evidentiary rulings.
Appeals are not opportunities to argue that the jury “got it wrong”. Instead, they are structured challenges to legal error, unreasonableness or miscarriages of justice.
Strict time limits apply, and success depends on carefully formulated legal grounds supported by the trial record. Anyone considering an appeal should seek prompt advice from a criminal lawyer experienced in appellate work to properly assess prospects and procedural requirements.
