- Erin Patterson appeals life sentence for the 2023 mushroom poisoning murders in Victoria
- Defence cites catastrophic mix-up with jurors staying at the same hotel as prosecutors
- Prosecutors defend mobile phone evidence and argue guilty verdicts were inescapable
- Appeal court judges in Melbourne have reserved their decision for upcoming weeks
Legal representatives for Australian convicted killer Erin Patterson have argued before the appeal court that her conviction was undermined by a catastrophic logistical error involving jurors staying at the same hotel as prosecutors and a key witness during deliberations.
Patterson is currently serving a life sentence after murdering three relatives and attempting to kill a fourth by serving a beef Wellington containing death cap mushrooms at her home in Victoria in 2023. Her victims included in-laws Don and Gail Patterson, both 70, along with Gail's sister Heather Wilkinson, 66, while Ian Wilkinson survived the meal.

During Wednesday's proceedings at the Court of Appeal in Melbourne, defence counsel argued that a retrial was necessary to ensure justice was seen to be done. Director of Public Prosecutions Brendan Kissane acknowledged the incident was regrettable but maintained it occurred by accident, questioning whether actual communication took place between jurors and outsiders.
The legal challenge highlights the critical importance of jury sequestration and procedural integrity in high-profile criminal trials. When defense teams point to logistical errors during deliberations alongside disputed digital evidence, it underscores how appellate courts must weigh the strict appearance of fairness against established factual records in complex poisoning cases.
Patterson's legal team also contested the inclusion of speculative evidence, including mobile phone tower data suggesting she searched for death cap mushrooms near locations reported on the iNaturalist platform, as well as critical Facebook messages sent to her estranged husband Simon Patterson and his parents months prior to the lunch.
Crown prosecutor Jeremy McWilliams defended the use of the telecommunications expert testimony to establish opportunity, while filing documents stating that the guilty verdicts were inescapable. Prosecutors will also cross-appeal Patterson's sentence, with the three appeal judges reserving their final decision for several weeks.
