Erin Patterson’s legal team argued in the Victorian Court of Appeal that sequestering jurors in the same hotel as lead investigators represented a catastrophic failure of justice, threatening her triple murder convictions during a high-profile appeal hearing.
Jury Sequestration and the Hotel Accommodation Dispute
Lawyers for triple murderer Erin Patterson argued before three judges of Victoria’s highest court that allowing jurors to stay in the same hotel as police and prosecution teams during deliberations represented a fundamental breakdown of the legal process. The appeal hearing, which opened on Wednesday, puts both Patterson’s conviction and her sentence under judicial scrutiny.
Patterson watched the proceedings via videolink from the Dame Phyllis Frost Centre, wearing a royal blue jumper and reviewing notes. Surviving victim Ian Wilkinson and other members of the Wilkinson and Patterson families sat in the front row of the public gallery as new barrister Richard Edney opened arguments by attacking the integrity of the trial.
“What we say has occurred here in the applicant’s trial was an inexplicable and perhaps still unexplained failure of a process. We would describe the sequestration and what occurred during it as catastrophic. There has been a fundamental failure here to comply with the dictum I’ve been referring to.”

The defense pointed out that the jury stayed in the same hotel as the homicide squad detective in charge of the case and lawyers from the office of public prosecutions. Edney argued that the arrangement undermined the principle that justice must not only be done, but be seen to be done, creating an environment susceptible to subconscious influence or inappropriate communication.
Judicial Scrutiny Over Evidence of Contact
When Justice Peter Kidd pressed the defense on whether any actual communication between jurors and investigators took place, Edney conceded there was no direct evidence of it. He maintained, however, that the lack of transparency and the absence of hotel CCTV footage created an evidentiary vacuum around the sequestration period.
Justice Kidd questioned whether physical proximity alone sufficed to invalidate a trial without proof of interaction, noting that jurors remained under the supervision of the designated jury keeper.
“Even if you’re right that communication can be non-verbal, surely there must be something more than simply seeing somebody. There can be a nod, a wink … there’s no evidence that’s occurred here. Maybe you won’t agree with me, but in this case it seems that the state of the evidence at all times was that there was no separation, and that the jurors were under the supervision of the jury keeper.”

Challenging Scientific Evidence and Mushroom Foraging Records
Beyond the jury accommodation issue, Patterson’s legal team advanced multiple additional grounds for appeal, targeting expert testimony and excluded evidence from the original trial. Veronika Drago, representing Patterson, argued that cell tower data presented by expert Dr Matthew Sorrell was dangerous and unfair.
The prosecution used that technical evidence to suggest Patterson visited two locations where death cap mushrooms were reported on a citizen science website. Defense lawyers also contended that trial judge Christopher Beale erred by ruling inadmissible certain photos and videos of mushrooms found on an SD card at Patterson’s home, material they argued supported her claim that she foraged for mushrooms.
Crown Appeal Against the Thirty-Three-Year Sentence
While Patterson seeks to overturn her convictions for the July 2023 murders of Don and Gail Patterson, both 70, and Gail’s sister Heather Wilkinson, 66, alongside the attempted murder of Ian Wilkinson, the state prosecutor is pushing in the opposite direction. Victoria’s top prosecutor, Brendan Kissane KC, maintains that the 33-year non-parole period handed down following her sentence to life imprisonment is manifestly inadequate.
The Court of Appeal judges must determine whether the combined grounds presented by the defense justify granting Patterson leave to challenge her conviction, even as the Crown argues for an extended prison term. The appeal hearings before Justices Stephen McLeish, Lesley Taylor, and Peter Kidd are scheduled to continue over subsequent days.
