Quick Summary

The Supreme Court of Victoria in Australia rejected Erin Patterson’s appeal against her conviction for murdering three relatives with death cap mushrooms and attempting to kill another by lacing beef wellington during a meal. The court ruled that Patterson should serve life imprisonment without the possibility of parole due to the “cold and calculated” nature of her crime, which included deceiving her family about a supposed cancer diagnosis to keep her children away from the deadly lunch. Judges dismissed Patterson’s arguments regarding unfair trial conditions and procedural issues, leaving her with no further legal recourse except for an application to the High Court.

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.
