Erin Patterson: The hotel booking snafu that could free mushroom murderer

Erin Patterson, convicted of poisoning her estranged husband’s relatives with mushroom-laced food in 2023, has filed an appeal challenging her convictions based on jury management during her trial. The case centers on a logistical failure that occurred during jury deliberations in the Gippsland region, where accommodation shortages created complications for sequestering the jury panel.

When the jury retired to deliberate, a national table tennis championship taking place in the region exacerbated existing accommodation shortages. The jury was housed separately on a dedicated floor of a hotel, with meals provided in a conference room, but the prosecution team—including the lead detective and two solicitors—was also staying at the same facility. Although the sequestered jurors used separate dining and meeting spaces, they shared common areas with members of the prosecution case. Additionally, an unspecified number of journalists covering the high-profile trial were present at the hotel. The trial judge received notification of this arrangement in an email on the day the jury reached its verdicts.

Patterson’s legal team argues this situation constituted a fundamental irregularity that compromised the integrity of the convictions. The defence contends that even without direct communication between jurors and prosecution personnel, the mere presence of trial participants could have created subconscious bias. The defence further emphasizes that no video recordings, sworn statements from those at the hotel, or documentation exists beyond two emails from the court, leaving what they describe as a “vacuum of evidence” about what transpired during this critical week.

The prosecution acknowledges the accommodation situation was undesirable but maintains that no inappropriate contact occurred between jurors and other parties. They note that those staying at the hotel took active steps to avoid common areas where they might encounter the sequestered jury. During appeal proceedings, Justice Peter Kidd questioned whether innocent proximity constituted a genuine problem, noting that jurors routinely encounter trial participants in various settings while under keeper supervision.

The appeal courts are now considering whether the jury arrangement was sufficiently compromised to warrant a retrial.
