EU delegation visit to Lanka mass grave site triggers protest; victims' families

Australian mushroom murderer Erin Patterson will learn Friday if she has succeeded in overturning her conviction for killing three people with a poisoned beef Wellington lunch.

A judge sentenced her to life imprisonment, eligible for parole after 33 years. On Friday at 10 am , the Court of Appeal will hand down its decision on both appeals, officials said.

They alleged a litany of irregularities in the trial, including an “oppressive” cross-examination and unfair decisions on the admission of evidence.

In August her lawyers argued before the Court of Appeal in Melbourne that she had suffered a miscarriage of justice.

If they agree to do so, the judges may dismiss the appeal or uphold it, in which case they may order a new trial or acquit her. On her sentence, the court will either dismiss the prosecution’s appeal or uphold it and re-sentence her.

Her trial last year drew podcasters, film crews and true crime fans to a courthouse in the rural town of Morwell, a sedate hamlet in Victoria better known for its prize-winning roses.
