In short:
Victoria's highest court has dismissed a bid by media outlets to lift a suppression order over secret evidence in the Erin Patterson case.
asserted
court → dismiss → case
The judges said, if published, the material would leave an "indelible impression" in the minds of jurors if Patterson was granted a re-trial on appeal.
What's next?
asserted
What → say → appeal
The suppression order will lift if Patterson fails to apply for special leave to appeal to the High Court by November 27.
asserted
Patterson → lift → November
Evidence in the Erin Patterson case that would receive "massive publicity" remains suppressed by Victoria's courts, three years after she murdered her relatives with a beef Wellington laced with death cap mushrooms.
asserted
she → receive → mushrooms
Last month, three judges of Victoria's Court of Appeal threw out Patterson's appeal against her convictions and changed her jail term to a life sentence without parole.
asserted
judges → throw → parole
However the judges refused to lift a suppression order over a piece of evidence, in case Patterson succeeds in a last-ditch appeal to the High Court and is granted a retrial.
asserted
Patterson → refuse → retrial
In a partially redacted judgment published online, the Court of Appeal said there was a danger Patterson would face "unfair prejudice" if potential jurors knew about the evidence.
asserted
jurors → redact → evidence
"While the evidence is nuanced and complex, it would be likely to attract very significant publicity with the potential to cause a real and substantial risk of prejudice to any future trial," Justices Stephen McLeish, Lesley Taylor and Peter Kidd wrote.
asserted
McLeish → attract → trial
For legal reasons, the ABC is unable to report details of what the evidence is.
asserted
evidence → report → details
In most legal matters, reporting restrictions are lifted at the end of a trial allowing publicity about things the jury did not hear.
asserted
jury → lift → things
The judges said this was an "exceptional case" and their ruling did not mean "contentious" pieces of inadmissible evidence would be automatically suppressed in other cases.
asserted
pieces → say → cases
Secret evidence would leave 'indelible impression' on potential jurors
The evidence was set to be included during Patterson's 2025 trial, where she was charged with murdering relatives Don Patterson, Gail Patterson and Heather Wilkinson, and attempting to murder Ian Wilkinson.
asserted
she → leave → Wilkinson
Midway through the trial, Justice Christopher Beale ruled the evidence inadmissible after hearing further legal argument, meaning the information never went before the jury.
asserted
information → rule → jury
Justice Beale suppressed the evidence after Patterson was found guilty, pending an appeal to Victoria's highest court, the Court of Appeal.
asserted
Patterson → suppress → Appeal
"[Justice Beale] found that the evidence would 'receive massive publicity' if publication were to be allowed," the appeal judges wrote.
asserted
judges → find → publicity
"It would 'leave an indelible impression on the minds of potential jurors in the event of a retrial'".
asserted
It → leave → retrial
The appeal judges decided to keep the suppression order in place, but said it would lift if Patterson failed to apply for special leave to appeal to the High Court by November 27.
asserted
Patterson → decide → November
Other suppressed details revealed last year
Media outlets, including the ABC, sought to have the suppression lifted after Patterson's appeal failed in the Court of Appeal last month.
asserted
appeal → suppress → Appeal
Media barrister Marcus Hoyne agreed that if published, the evidence would remain in the forefront of the public's mind until a hypothetical future retrial.
asserted
evidence → agree → retrial
However, he said, any such trial would face an extensive delay and a judge could properly instruct a jury about the evidence and explain why it had been ruled irrelevant and inadmissible.
uncertain
it → say → evidence
But the judges ruled publicity of the evidence posed a risk to the proper administration of justice.
asserted
publicity → rule → justice
"…it would be highly undesirable, to say the least, for jurors to be aware of the evidence the subject of the present application," they wrote.
asserted
they → say → application
All seven grounds of the mushroom killer's appeal were dismissed last month, with the judges calling her crimes "extraordinarily cold and calculated".
asserted
judges → dismiss → crimes
"On any view, these were heinous crimes,"the judges said.
asserted
judges → say → view
In 2025, other suppression orders were lifted over other material that was excluded from the trial.
asserted
that → lift → trial
It included claims Patterson had tried to murder her estranged husband Simon — unproven allegations that she denied, which were dropped by the prosecution.
uncertain
which → include → prosecution
Other suppressed details included material found on Patterson's computers, such as a book appendix titled "Some common homicidal poisons", a study about red kidney bean poisoning in the UK, and a paper on abrin, a highly toxic compound found in rosary pea seeds.
asserted
details → suppress → seeds
