Victoria's Court of Appeal on Friday dismissed Erin Patterson's appeal against murder convictions in the Australian death-cap mushroom case and upheld a prosecution challenge to her sentence, ABC News Australia and The Guardian reported^1,2.

Patterson was convicted of murdering three relatives after a lunch of beef Wellingtons that contained death cap mushrooms, ABC said². The Guardian's live court report said those victims were her estranged husband's parents, Don and Gail Patterson, and his aunt Heather Wilkinson, and that she was also convicted of the attempted murder of Heather's husband, Ian Wilkinson, who survived¹.

ABC said she had mounted an appeal on seven grounds, that all but two were dismissed before the remaining grounds were heard, and that those remaining grounds were also dismissed². The Guardian's live blog likewise said she lost her bid to overturn the convictions after the court found unsuccessful or rejected all seven grounds her lawyers had argued¹.

A separate appeal by prosecutors seeking a harsher sentence was upheld, and Patterson will be re-sentenced, ABC reported². The Guardian said the director of public prosecutions succeeded and that she will be resentenced to life without parole¹. ABC said the decision means it is likely Patterson will die in jail².

The Guardian reported she had been sentenced last year to life imprisonment with a 33-year non-parole period¹. Its live coverage said she appeared by video link from Dame Phyllis Frost Centre and that Ian Wilkinson was not in court for the ruling¹.

ABC said it was still adding details to a breaking brief². The full written reasons of the Court of Appeal were not excerpted in either account at the time of filing^1,2.
