Attorneys for Robert Neulander have filed an appeal for his second murder conviction.
The former OBGYN was convicted once again last May of killing his wife in 2012.
His first trial, where he was also convicted, was thrown out in 2018 after accusations of juror misconduct.
His second trial was then delayed by the COVID-19 pandemic, allowing him to be out on bail for over two years.
The 71-year-old is currently serving a sentence of 20 years to life.
