Mushroom murder appeal: defence cites "catastrophic" hotel mix-up involving jury and prosecutors

Lawyers for Erin Patterson, convicted of murder in Australia's high-profile mushroom poisoning case, argue her conviction was undermined by a "catastrophic" mix-up in which the jury stayed at the same hotel as prosecutors and a key witness. The defence says the incident compromised the fairness of the trial. The case is currently being heard on appeal.
