Tribble was convicted twice of murder, before those convictions were overturned.
Tuesday, the 63-year-old will be in court to question the reliability of witnesses from his prior trials.
Tribble was accused of shooting and killing Michael Borello, 43, in North Wolcott in 2000. Tribble pleaded not guilty to those second-degree murder charges. He claimed he acted in self-defense, shooting his pistol first and then heading to his truck to get his shotgun before striking the unarmed man several times when Borello tried to get away.
Last December, the Vermont Supreme Court ruled Tribble's judge made several mistakes. His first conviction was also tossed.
