In short:
Erin Patterson will today learn whether she has won an appeal against her convictions for murdering three lunch guests and trying to kill a fourth with poisonous mushrooms in 2023.
asserted
she → learn → 2023
If the Court of Appeal quashes her convictions, it could either order a retrial or acquit her of the charges.
The court will also hand down a decision on a prosecution bid to keep Patterson behind bars for the rest of her life.
Triple-murderer Erin Patterson will learn within hours whether she has won her appeal against her convictions.
uncertain
she → quash → convictions
Patterson is serving three life sentences with a non-parole period of 33 years after a jury found her guilty of murdering her parents-in-laws Don and Gail Patterson, along with Gail's sister, Heather Wilkinson, in 2023.
asserted
her → serve → 2023
The victims had been invited to lunch at Patterson's Leongatha home, in Victoria's south-east, where she served them death cap mushrooms inside beef Wellington.
asserted
she → invite → Wellington
Patterson, 52, was also found guilty of the attempted murder of Mrs Wilkinson's husband, Korumburra church pastor Ian Wilkinson, who survived after falling gravely ill from the poisoning.
asserted
who → find → poisoning
Patterson lodged an appeal against the jury's verdicts, claiming there was a substantial miscarriage of justice during her trial, which was held in the regional town of Morwell in 2025.
asserted
which → lodge → 2025
Patterson's lawyers told a two-day appeal hearing in August there had been a "catastrophic" accommodation bungle during the deliberations over the verdicts, which saw the jury staying at the same hotel as the main police witness for the prosecution, as well as two members of the prosecution team.
asserted
jury → tell → team
The defence made lengthy submissions about the risk of the jury being influenced by any direct and indirect contact with the parties, even as simple as a jury member seeing one of the others through a hotel window.
asserted
member → make → window
It also argued that prosecutor Nanette Roger SC's cross-examination of Patterson was "unfair and oppressive".
asserted
examination → argue → Patterson
Patterson's lawyers told the court the five-day questioning included, at times, terse exchanges which posed a risk of creating improper inferences in the jury members' minds.
asserted
which → tell → minds
They also accused Dr Rogers of changing the prosecution case during her closing addressing by implying there was a motive for the murders after telling the jury there was no evidence of a motive when she was opening the case.
asserted
she → accuse → case
Prosecution's fight to lock up Patterson for life
When handing down Patterson's life sentence, Justice Christopher Beale set a 33-year non-parole period.
asserted
Beale → lock → period
That means Patterson could be released back into the community when she's in her early 80s.
uncertain
she → mean → 80s
The prosecution's appeal against that minimum term focused on the severity of Patterson's crimes and the conditions she would face in jail.
asserted
she → focus → jail
The team argued that a life sentence without parole was the only option given the number of Patterson's victims, the amount of planning that went into the deadly lunch, the continuation of the offending by not revealing the poisoning to medical staff when there was a chance to treat the victims, and a lack of remorse displayed by Patterson.
asserted
that → argue → Patterson
The prosecution also argued Justice Beale should not have made an allowance for Patterson facing years in protective custody because of her notoriety.
asserted
Patterson → argue → notoriety
The appeal court heard Patterson had access to a library, recreation centre, exercise yard and treadmill, had regular video calls with her children and engaged in hobbies such as crocheting.
asserted
Patterson → hear → crocheting
What could happen today
uncertain
What → happen → ?
Despite already hearing the appeal arguments, Court of Appeal judges Lesley Taylor, Stephen McLeish and Peter Kidd must first rule whether Patterson's case has met the requirements to be granted leave to appeal.
asserted
case → hear → leave
That means there are four possible outcomes for Patterson's appeal:
- The court may rule leave has not been granted to appeal, which means Patterson's appeal was judged to be without merit before her detailed arguments were more deeply considered.
- Leave to appeal may be granted but the case may be dismissed, meaning the judges were not convinced by Patterson's lawyers that there had been a miscarriage of justice.
- Leave to appeal may be granted and the judges may announce that "the appeal has been upheld".
uncertain
appeal → mean → justice
That would mean that Patterson has won her appeal against her convictions.
asserted
Patterson → mean → convictions
The judges may then order the entire trial be held again.
uncertain
trial → order → ?
- Leave may be granted, the appeal upheld but the judges may decide, based on the evidence presented to support Patterson's submissions, that the jury's verdicts should be quashed and Patterson be acquitted of all charges and released from prison.
If a retrial is ordered or the court acquits Patterson, the prosecution's appeal against the sentence is no longer relevant.
uncertain
appeal → grant → sentence
If Patterson loses her appeal, the judges will then turn to the prosecution's appeal.
asserted
judges → lose → appeal
If that appeal is dismissed, the original sentence of life imprisonment with a minimum term of 33 years set by Justice Beale remains in place.
asserted
sentence → dismiss → place
If the appeal is upheld, the Court of Appeal will announce Patterson's new sentence.
asserted
Court → uphold → sentence
Due to the large media and public interest in the case, the decision will be handed down in Court 1 of the Victorian Supreme Court, not in the usual Court of Appeal building.
asserted
decision → hand → building
Patterson is not expected to attend today's hearing in person.
asserted
Patterson → expect → person
