Story summary

Erin Patterson, a 51-year-old Australian woman, is appealing her conviction for murdering three relatives and attempting to kill another by serving them a meal containing death cap mushrooms. She was found guilty in July last year of killing her husband's parents, Don and Gail Patterson, and his aunt Heather Wilkinson, at her home in Leongatha, Victoria, and sentenced to life in prison with the possibility of parole after 33 years. Patterson's lawyers argue that the jury sequestration was fundamentally flawed because jurors were housed in the same hotel as the police and media, which could have influenced their verdict. The prosecution is also appealing against the sentence, arguing that a 33-year parole period is "manifestly inadequate" given the severity of the crimes. In a separate challenge, Crown prosecutors are urging the court to reject Patterson's appeal, stating that her crimes were "truly dreadful" and that she should never be allowed to leave prison. The Court of Appeal in Melbourne will reserve its decisions on both appeals, meaning it could take weeks or months before the outcome is known.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
