In brief

Erin Patterson, convicted of murdering three relatives by serving them beef Wellington laced with death‑cap mushrooms, faces a new appeal after the court highlighted a hotel accommodation mix‑up that exposed the jury to potential influence. Lawyers argue the jury’s stay alongside prosecutors, a key witness and reporters undermined the integrity of the verdict and warrants a retrial. The appeal also challenges specious mobile‑phone tower evidence and certain Facebook messages, filing that key evidence was excluded unfairly. Meanwhile Victoria’s Director of Public Prosecutions is contesting Patterson’s 33‑year parole period, calling it "manifestly inadequate". The outcome will only be decided once the appeal judges reserve their decision, a process that may take several weeks.

Hotel Controversy Re‑opens Erin Patterson Case

The Victorian Court of Appeal has heard arguments that a hotel accommodation misstep may have compromised the integrity of the murder trial that saw Erin Patterson convicted of killing three relatives with death‑cap mushrooms.

Patterson, 51, is serving a life term after ordering homemade beef Wellington that killed her in‑laws Don and Gail, and a 66‑year‑old relative Heather. The tryst reportedly involved the addition of the deadly mushroom to the dish.

Defence counsel Richard Edney noted that the jury spent the trial on a hotel floor that also housed prosecution staff, a key police witness and journalists. He said this situation was a "catastrophic" flaw that called the verdict into question and therefore demanded a new trial.

The prosecution, represented by Director of Public Prosecutions Brendan Kissane, admitted the hotel mix‑up was accidental but insisted the jury had no communications with outside parties, calling the allegation a mere inference. He argued no "irregularity" fundamentally affected the trial.

Additional issues that surfaced on appeal include speculative mobile‑phone tower evidence that placed Patterson near two suspected mushroom locations, and Facebook messages sent months earlier that were deemed irrelevant. Defence lawyers sifted the evidence as unfairly prejudicial and wrongly excluded.

Patterson herself watched the appeal from prison via a video link, while her estranged husband, who was meant to attend the originally planned dinner, cancelled last minute on suspicion of past poisoning attempts.

The appeal judges will reserve their decision for several weeks. In the meantime, the prosecution will continue to contest both the appeal arguments and Patterson’s proposed parole after 33 years, arguing it does not reflect the seriousness of her crimes.
