Victoria’s Court of Appeal has heard prosecutors argue that Erin Patterson should have been sentenced to spend the rest of her life in prison with no chance of release, or at least a non-parole period so long she would likely die in custody. The submission came as the Director of Public Prosecutions pursues a separate appeal against her sentence, arguing it was “manifestly inadequate” for the killing of three of her estranged husband’s relatives.
Patterson, 51, was convicted last year of the murders of Don and Gail Patterson and Gail’s sister Heather Wilkinson, and the attempted murder of local pastor Ian Wilkinson, after the four were served a beef Wellington lunch laced with death cap mushrooms at her Leongatha home in 2023. She is now appealing against her convictions on seven grounds, while the DPP is separately arguing the sentence handed down to her did not adequately reflect the gravity of her offending.
What the Court of Appeal is being asked to decide #
The appeal now before Victoria’s Court of Appeal is, in effect, two cases running side by side. Patterson’s own legal team is asking the court to overturn her convictions entirely, pointing to seven separate grounds they say undermine the jury’s verdict. At the same time, the Crown is pushing in the opposite direction, arguing that even if the convictions stand, the sentence imposed by the trial judge was too lenient given the scale of what occurred.
A Crown prosecutor told the court that all seven of Patterson’s grounds for appeal should fail, according to court documents seen by VCN. The prosecution’s position, as put to the appeal judges, is that Patterson’s conduct — the deaths of three people and the serious harm caused to a fourth — warranted either a sentence of life imprisonment without any prospect of parole, or a non-parole period long enough that release would be improbable within her lifetime.
Background to the case #
Patterson was found guilty following a lengthy trial in the Supreme Court sitting at Morwell, in Gippsland, which drew national and international media attention over its ten-week course. The court was told the four lunch guests fell seriously ill after eating individual beef Wellington parcels at Patterson’s home in July 2023. Don and Gail Patterson and Heather Wilkinson died in the days that followed. Ian Wilkinson survived after a lengthy stay in hospital.
At trial, the prosecution’s case centred on evidence that death cap mushrooms, one of the world’s most toxic fungi, had been deliberately included in the meal. Patterson’s defence maintained she had not intended to harm her guests and that any poisoning was accidental. The jury ultimately rejected that account, returning guilty verdicts on all charges. Patterson was sentenced by the trial judge to a term of imprisonment with a non-parole period, a sentence the DPP now argues fell short of what the offending demanded.
Why prosecutors say the sentence was too soft #
In arguing the sentence was manifestly inadequate, the Crown’s submission to the Court of Appeal focused on the number of victims, the degree of planning alleged to have been involved, and the breach of trust inherent in a family lunch turning fatal. Prosecutors told the court that a case involving three deaths and an attempted murder sat at the most serious end of the scale for criminal offending in Victoria, and that the sentence needed to reflect both punishment and the protection of the community.
Victoria Police has not commented further on the appeal given the matter remains before the courts, referring inquiries to the Office of Public Prosecutions. It is understood the appeal hearing is expected to run over several days, with both Patterson’s defence team and Crown prosecutors making extended submissions to a panel of Court of Appeal judges.
The grounds of Patterson’s own appeal #
Patterson’s legal team has raised seven grounds in seeking to have her convictions quashed. Court documents outlining the appeal have not been fully detailed publicly, and VCN is not in a position to canvass matters that may touch on rulings made during the trial that remain subject to ongoing legal argument. What is on the public record is that the Crown urged the appeal judges to reject each of the seven grounds put forward, telling the court there was no proper basis to disturb the jury’s verdict.
Legal observers note that appeals against conviction in Victoria are determined on strict legal principles — the Court of Appeal does not re-run the trial or re-weigh the evidence as a jury would, but instead considers whether legal errors occurred that could have affected the verdict, or whether the verdict was unreasonable having regard to the evidence. That threshold is deliberately high, reflecting the weight the justice system places on jury decisions reached after a full trial.
How sentence appeals work in Victoria #
For readers unfamiliar with the process, a DPP appeal against sentence is a distinct legal avenue from an appeal against conviction. Under Victorian law, the prosecution can ask the Court of Appeal to increase a sentence if it can demonstrate the original sentence was “manifestly inadequate” — a legal test that requires showing the sentence was so far outside the appropriate range that it amounts to an error, not simply that a longer sentence might have been preferable.
These appeals are relatively uncommon and are reserved for cases prosecutors consider clear departures from an appropriate sentencing range. If successful, the Court of Appeal has the power to quash the original sentence and impose a new one, which could include a longer non-parole period or, as argued in this case, a sentence of life imprisonment without parole.
What happens next #
The Court of Appeal has reserved its decision on both matters — Patterson’s conviction appeal and the DPP’s sentence appeal — with judgment expected to be handed down at a later date. Victoria Police said in a statement previously issued at the time of sentencing that the case had involved an extensive and complex investigation, though the force has declined to comment further while the appeal is before the court.
Patterson’s convictions remain in place while the appeal is determined. The matter is currently before the courts, and the outcome of both the conviction appeal and the Crown’s sentence appeal will not be known until the Court of Appeal delivers its judgment. All persons remain entitled to the full appeal processes available under Victorian law, and Patterson is presumed innocent of nothing beyond what has already been determined by the jury unless and until the Court of Appeal finds otherwise.
