Triple murder
Erin Patterson’s bid to overturn her convictions was rejected on Friday, leaving the 52‑year‑old with a life sentence and no chance of release. The Court of Appeal in Melbourne heard arguments on two appeals related to the triple murder case that shocked the state last year. Patterson, who did not appear in person, watched the 15‑minute hearing via video link as Justice Stephen McLeish explained why the appeal failed and why the Director of Public Prosecutions succeeded in securing a longer sentence.
Patterson had been sentenced last year to life imprisonment with a 33‑year non‑parole period for the murders of her estranged husband’s parents, Don and Gail Patterson, and his aunt, Heather Wilkinson. The victims died after eating a lunch that Patterson prepared, which was later found to contain death‑cap mushrooms. The court also upheld her conviction for the attempted murder of Heather’s husband, Ian Wilkinson, who survived a mushroom‑laced beef Wellington but spent weeks in hospital.
During the hearing, Justice McLeish noted that the appeal was granted leave on the first two grounds raised by Patterson’s lawyers but was dismissed, along with the five additional grounds. He added that the DPP’s appeal against the original sentence was allowed because the initial term did not reflect the gravity of the offences. “Patterson sustained an intent to murder all four people for three weeks, from the time they were invited to the lunch, during the meal, and during the protracted suffering and ultimate deaths that resulted,” he said.
The judges described the conduct as “carefully planned and deliberate,” highlighting a series of deceptions that included false claims of cancer, denial of foraging mushrooms, and lies about the mushrooms’ source. Justice McLeish called the offending “extraordinarily cold and calculated” and said it must be denounced in the strongest possible terms. After the judgment, Patterson stood, took a book placed beside her, and walked off‑screen, while family members in the courtroom embraced and detectives involved in the investigation appeared relieved.
Patterson now faces the option of seeking leave to appeal to the High Court if she wishes to continue contesting either the conviction or the new sentence. A small group of Victorian offenders have been handed life without parole, and Patterson is among the very few women in Australian history to receive such a penalty. The court had previously considered that she should receive either no possibility of release or a non‑parole period so long that she would likely die in custody.
Her legal team had presented seven grounds for appeal, arguing that jurors had stayed in the same hotel as police and prosecutors while deliberating, a circumstance they described as a “catastrophic” failure of the justice system. Senior counsel Richard Edney, representing Patterson, called the failure to separate the jury a “fundamental irregularity” that denied a fair trial. He told the court that the situation was “inexplicable and perhaps still unexplained.”
Another point of contention was the admissibility of photographs and videos of mushrooms found on an SD card in Patterson’s home. Her lawyers claimed the trial judge, Christopher Beale, erred in ruling those items inadmissible, asserting they supported her defence that she had foraged the mushrooms herself. The DPP’s barrister, Brendan Kissane KC, countered that even if Patterson were to reach her 80s before becoming eligible for parole, the sentence remained too lenient given the seriousness of the conduct. When asked whether a longer non‑parole period effectively condemned her to die behind bars, Kissane replied, “It has its harsh aspect to it, of course, we accept that. But in our submission that is not a matter that is outweighed by the seriousness of the offending.”
The case has drawn public attention not only because of the gruesome method of killing but also due to the rarity of life‑without‑parole sentences for women in Australia. Legal experts note that the decision reinforces the courts’ willingness to impose the maximum penalty when pre‑meditation, deception, and extreme cruelty are proven. For victims’ families, the upheld sentence provides a measure of closure after a prolonged and emotionally draining trial.
As the legal process moves forward, Patterson’s next step will be to decide whether to apply to the High Court for permission to appeal. If granted, the higher court could review both the conviction and the sentence, though such applications are rarely successful in cases where the appellate courts have already found the original judgment sound. Until then, Patterson remains in custody, serving a term that, under current law, will likely last the rest of her life.
The decision also serves as a reminder to the criminal justice system of the importance of procedural fairness, especially regarding jury management and evidence admissibility. While the court affirmed the original findings, it show that any deviation from established trial standards could be a basis for appeal. For now, the Victorian legal community and the public will watch closely to see whether Patterson pursues further recourse or accepts the finality of the Court of Appeal’s ruling.
