Erin Patterson, serving a life sentence for murdering three relatives with death‑cap mushrooms, is on appeal after a court discovered a key flaw: jurors stayed in the same hotel as prosecutors, a key witness, and journalists.


Patterson’s lawyers maintain the hotel stay exposed jurors to influences that could have altered their impartiality, calling the mistake “catastrophic” and demanding a full retrial to restore trust in justice.


The original 2023 trial saw prosecutors argue Patterson had hunted death‑caps after a couple of sightings near her hometown announced on the citizen‑science platform iNaturalist. Phone‑tower data was presented to show a possible route, but defence counsel argue this evidence was speculative and unverified.


Additionally, Facebook messages sent months before the fateful lunch were admitted, while the defence said they were irrelevant and prejudicial. The prosecution’s closing remarks and cross‑examination of witnesses were also flagged as problematic.


Meanwhile, Victoria’s Director of Public Prosecutions is contesting the 33‑year parole period, describing it as “manifestly inadequate.” The prosecution has indicated it will appeal this part of the sentence as well.


The three‑judge panel will reserve its decision, meaning it may take weeks before a final verdict is announced. The case underscores the importance of strict courtroom protocols and raises broader questions about life‑sentence parole and legal fairness in high‑profile criminal cases.
