Erin Patterson, convicted of murdering three relatives with a poisoned beef Wellington laced with death cap mushrooms, has begun an appeal against her conviction and sentence. Her legal team argues she suffered a miscarriage of justice during the high-profile trial, which attracted intense global media attention and scrutiny of Australia's criminal justice system.

The appeal centres on claims that errors were made during proceedings that undermined the fairness of her original trial and conviction. Patterson was found guilty of triple murder after serving the fatal meal to family members, a case that became one of Australia's most closely watched criminal trials in recent years.
