Secret evidence in Erin Patterson mushroom murder case to stay hidden

Victoria's highest court has refused to lift a suppression order on secret evidence in the Erin Patterson case, saying it could cause unfair prejudice if she gets a retrial. Patterson is currently serving a life sentence without parole after being convicted of murdering three relatives and attempting to kill a fourth with a deadly beef Wellington laced with death cap mushrooms.

Court Ruling

Three judges on the Court of Appeal threw out Patterson's appeal last month and called her crimes cold and calculated. However, the judges kept the suppression order in place to protect a fair trial. They warned that the material would leave an indelible impression on potential jurors' minds if published now. Media outlets had asked the court to lift the order, arguing that judges can instruct juries to ignore irrelevant details, but the court ruled that the publicity posed a real risk to justice.

Next Steps

Justice Christopher Beale originally ruled the evidence inadmissible during the 2025 trial after hearing legal arguments, meaning the jury never saw it. The current suppression order will only lift if Patterson fails to apply for special leave to appeal to the High Court by November 27. Other suppression orders were lifted last year regarding unproven allegations that she tried to murder her estranged husband Simon, along with computer search details about homicidal poisons and toxic compounds.

Context

Suppression orders are legal tools used by courts to temporarily ban the publication of certain details so that a fair trial or appeal process is not ruined by public bias. In high-profile criminal cases, preventing jurors from seeing sensitive material before or during court proceedings helps protect the basic right to an unbiased hearing.
