In brief

In July 2023, a sequestered jury for the Erin Patterson murder trial was forced to share a hotel with prosecution lawyers and a key witness because of lodging shortages caused by a fringe table‑tennis event. Early‑morning emails revealed the overlap, prompting a legal team to argue a fundamental irregularity and seek a retrial. Prosecutors insist no contact occurred, citing rigorous supervision. Lacking CCTV or third‑party witnesses, the case hinges on perception of potential interference. The appeal is now under judicial review, while the prosecution seeks to maintain Patterson’s parole restrictions.

In a small Victorian town, the drama of a murder trial was set against a backdrop of sport, hotels and justice. Hundreds of table‑tennis fans descended on Gippsland last July for the national championships, swelling the town’s accommodation needs to a record high.

The trial of Erin Patterson – the woman convicted of poisoning her estranged husband’s relatives with a mushroom‑laden lunch – was rife with logistical challenges. The court decided to sequester a 12‑person jury, requiring them to be isolated in a separate apartment of a local hotel. However, on the week the table‑tennis tournament reached its peak, every available room was booked and the jury had to share the complex with key prosecution personnel, a detective and several journalists.

Testimony surfaced in an email from the judge’s chambers, sent at 08:28 on Monday 7 July. It clarified that the detective and two prosecution solicitors had booked the same floor of the hotel as the jurors, though the jurors and the prosecution kept to separate suites and met only in a dedicated conference room. The judge noted that “concerns about accommodation shortage” had led to the clash, but also warned that this was “undesirable.”

Patterson’s defence, led by barrister Richard Edney, used the email to argue a “fundamental irregularity” that “fatally undermined” the fairness of the verdicts. “What occurred here was an inexplicable and perhaps still unexplained failure in the process,” Edney told the Court of Appeal, calling the situation “catastrophic.” He argued that even fleeting, subconscious contact could have influenced jurors.

In response, the Director of Public Prosecutions Brendan Kissane KC said that the system worked as intended. He emphasized that the jury was supervised, and that steps were taken to avoid any encounter. He argued that the appeals of past cases cited by the defence all suffered from confirmed interaction, whereas “that is not the situation here.”

The crucial question now is perception: whether the appearances of possible interference justify a retrial, or whether the rigorous sequester and lack of evidence of actual interaction absolve the verdict. The judges are deliberating and will announce their decision later. In the meantime, the approval of Patterson’s parole period remains in dispute, as prosecutors seek its revocation.
