A major criminal justice development took place in Victoria on 30 October 2026, when the Court of Appeal rejected Erin Patterson's challenge against her murder convictions and increased her sentence to life imprisonment without the possibility of parole.

The decision follows one of Australia's most widely followed criminal cases, involving a deadly mushroom lunch hosted by Patterson at her home in Leongatha, Victoria, in July 2023. The meal resulted in the deaths of three people: Don Patterson, Gail Patterson and Heather Wilkinson. Heather's husband, Ian Wilkinson, also became seriously ill but survived.

Patterson was convicted of three murders and one attempted murder following a high-profile trial. In September 2025, she received three life sentences, with a minimum non-parole period of 33 years. This meant she could potentially apply for parole after serving that period.

However, prosecutors believed the original sentence was not sufficiently severe given the circumstances of the crimes. They appealed the sentencing decision, arguing that Patterson should never have the opportunity to be released from prison.

At the same time, Patterson challenged her convictions, arguing that problems during the trial had affected the fairness of the proceedings. Her legal team raised several grounds of appeal, including concerns about jury arrangements and the admission of mobile phone evidence.

On 30 October, a three-judge Court of Appeal panel, including Justice Stephen McLeish, delivered its decision at the Supreme Court of Victoria in Melbourne. The court rejected Patterson's appeal against her convictions after considering the arguments presented by her defence team.

The court also accepted the prosecution's argument that the original sentence was inadequate. As a result, the non-parole period was removed and Patterson was resentenced to life imprisonment without parole.

The decision means she will not be eligible for release through the ordinary parole process. It represents a significant outcome in the legal proceedings and closes an important stage of the case.

During the appeal proceedings, the court also considered arguments about Patterson's prison conditions. Her lawyers had described her confinement as particularly restrictive, while prosecutors maintained that the seriousness of the crimes justified the sentence they were seeking.

The judges considered the legal arguments from both sides before delivering their final decision. The ruling reflects the court's assessment of the seriousness of the offending and the evidence considered during the original proceedings.

The case has attracted national attention because of the unusual circumstances surrounding the deaths, the impact on the affected families and the extensive investigation that followed the lunch.

The outcome has also renewed public discussion about sentencing standards, criminal appeals and the role of parole in Australia's justice system.

For the families affected by the deaths, the decision marks another significant moment in a long legal process. Although the appeal proceedings have concluded at this level, any further legal challenge would face strict requirements under Australian law.

The ruling is one of the major court developments reported in Victoria on 30 October 2026.
