Erin Patterson Sentenced to Life for Mushroom Murders, DPP Appeals

The Director of Public Prosecutions appeals Erin Patterson's sentence, arguing it is 'manifestly inadequate.' Erin Patterson also appeals her conviction, with a central argument focusing on the jury's accommodation during deliberations.

The jury reportedly stayed in the same hotel as the police informant and prosecution lawyers. Erin Patterson's lawyers argue this arrangement denied her a fair trial, claiming it was a 'fundamental irregularity.'

Richard Edney claims the failure to properly separate the jury during their deliberations constituted a fundamental irregularity that denied Erin Patterson a fair trial. Edney asserts the sequestration and its circumstances were catastrophic, representing a fundamental failure to comply with the dictum that 'justice not only to be done, but to be seen to be done.'

An evidentiary vacuum reportedly surrounds the sequestering, with no CCTV available from the hotel and the jury unable to be questioned, Edney claims. Erin Patterson's lawyers also argued that her cross-examination was 'unfair and oppressive' and lasted about six days.

Erin Patterson's lawyers further argued that the prosecutor's closing address caused a substantial miscarriage of justice due to alleged misstatements of evidence. Erin Patterson also argues that evidence from her Facebook 'friends' should not have been allowed as it was not 'relevant.'

The prosecution reportedly used cell tower evidence and evidence of death cap mushroom sightings to infer Erin Patterson's movements. However, Erin Patterson's lawyers claim this cell tower evidence and evidence of death cap mushroom sightings should not have been allowed in the trial as it was not relevant, or its value was outweighed by its unfair prejudice to Erin Patterson.

Veronika Drago claims the cell tower evidence was 'dangerous' and 'unfair.' Three judges of Victoria's highest court are hearing the appeal.

Simon Patterson, the estranged husband, was invited to the lunch but did not attend. Prosecutors dropped charges relating to him before the trial began in April 2025.
