Overview
- The Victorian Court of Appeal begins a two-day hearing on Wednesday to decide if Patterson is granted leave to launch a full appeal and to hear the prosecution's separate bid to increase her sentence.
- Patterson has asked the court to review seven grounds alleging miscarriage of justice, including that her five-day cross-examination was unfair, that prosecutors shifted their case in closing submissions, and that key technical evidence was wrongly admitted or excluded.
- Her appeal also relies on a confirmed sequestration irregularity when jurors unknowingly stayed at the same hotel as the lead detective and two prosecution staff, which her lawyers say undermined the verdicts.
- Prosecutors have cross-appealed the September 2025 sentence, arguing the 33-year non-parole period is manifestly inadequate and asking for a longer minimum term or life imprisonment without parole.
- The underlying case began with a July 16, 2023 Leongatha lunch where beef Wellington tainted with lethal death cap mushrooms killed three relatives and gravely ill one survivor, and any Court of Appeal ruling could leave convictions intact, order a retrial, quash verdicts, or lead to re‑sentencing.
