Erin Patterson Appeal Verdict: Mushroom Murder Convictions Decision 2026

Erin Patterson's appeal against her triple murder conviction will be decided on Friday, when Victoria's highest court hands down its ruling on whether her convictions for the mushroom murders should stand. The court of appeal will rule on two separate appeals from 10am, after hearing arguments in August.

Patterson was sentenced last year to life imprisonment with a non-parole period of 33 years for the murders of her estranged husband's parents, Don and Gail Patterson, and his aunt Heather Wilkinson. She was also convicted of the attempted murder of Heather's husband, Ian Wilkinson, who survived the poisoned beef wellington lunch after spending weeks in hospital.

What the Court Will Decide on Friday

The court of appeal will rule on two appeals: one against Patterson's convictions and one against her sentence. Patterson is not expected to attend the decision in person.

There are four possible outcomes for the conviction appeal: leave to appeal is not granted; leave to appeal is granted but the appeal is dismissed; leave to appeal is granted, the appeal is upheld and a retrial is ordered; or leave to appeal is granted, the appeal is upheld and an acquittal is entered.

If either of the final two outcomes occurs, there will be no need to rule on the sentence appeal. If not, the sentence appeal will be decided, meaning Patterson could either fail in her appeal or succeed and be resentenced.

Why the Appeal Matters

The case has drawn intense public interest due to its shocking nature: a family lunch that turned deadly. The appeal is significant not only for Patterson but also for the victims' families, who have endured a lengthy legal process.

In August, the court heard arguments that Patterson should have been given no possibility of ever being released from prison. This suggests the Crown may be seeking a harsher sentence if the appeal against conviction fails.

The decision will also set a precedent for how similar cases are handled in Victoria, particularly regarding sentencing standards for multiple murders.

Key Points from the Appeal Hearing

• The appeal was heard in August, with judgment reserved until Friday.
• Patterson was convicted of three murders and one attempted murder.
• She was sentenced to life with a 33-year non-parole period.
• The court will consider both conviction and sentence appeals.
• Possible outcomes range from acquittal to a retrial or dismissal.

Possible Outcomes and Their Implications

If Patterson's appeal against conviction is upheld and a retrial is ordered, the case would return to the Supreme Court for a new trial. This would mean the victims' families would have to endure another lengthy process.

If an acquittal is entered, Patterson would be released, though this is considered unlikely given the strength of the evidence presented at trial. If the appeal is dismissed, her convictions stand, and the court will then consider the sentence appeal.

The sentence appeal could result in a longer non-parole period if the court accepts the argument that Patterson should never be released. Alternatively, it could be reduced if the court finds the original sentence was excessive.

What This Means for the Victims' Families

The families of the victims have waited through the trial and now the appeal. A decision on Friday will bring some closure, but if a retrial is ordered, they may face further heartache.

The case has already had a profound impact on the small community of Leongatha, where the lunch took place. The appeal decision will be watched closely by those affected.
