MELBOURNE: A Victorian Court of Appeal justice is due to rule Friday on the case of Erin Patterson, who was sentenced last year to life in prison with a 33-year non-parole period for poisoning three relatives with death cap mushrooms served in a beef Wellington lunch.

Patterson, 52, was convicted of murdering her former in-laws Gail and Don Patterson and Gail's sister Heather Wilkinson, who fell ill after eating the meal prepared at her home in Leongatha, a town about two hours southeast of Melbourne, in 2023. All three died within days. Ian Wilkinson, Heather's husband, spent time in intensive care, recovered and later testified at trial. Patterson had also invited her husband to the lunch; he cancelled the night before. The couple were separated.

Patterson has maintained the deaths were an accident and testified on her own behalf at trial. She is not expected to appear in court when the decision is delivered.

Her defence team has asked the court to overturn the conviction, arguing the jury in the widely followed case was not sequestered sufficiently, that prejudicial evidence was admitted, and that the prosecution's closing arguments went too far. Counsel for Patterson have also argued that the inclusion of certain evidence amounted to a substantial miscarriage of justice.

Prosecutors have filed their own appeal against the sentence. They told the court that a 33-year non-parole term was "manifestly inadequate" for crimes they called "truly dreadful" and "a vile crime without redeeming features." They also argued the sentencing judge erred in weighing the likelihood that Patterson would be held in solitary confinement, saying the media attention surrounding the case was a consequence of her own actions.

If the court sides with Patterson, judges could quash the conviction and order a retrial, or overturn it and enter an acquittal. The case has drawn sustained attention in Australia, with podcasts, books and a fictionalised television series built around the lunch and its aftermath.
