The six men accused of being involved in a small riot at Her Majesty's Penitentiary in St. John's in August have pleaded not guilty to hostage taking and other charges.
The men made a court appearance on Wednesday, and elected to be tried in provincial court.
The other charges are for damaging property and having their faces covered.
During the disturbance, a door that was ripped off a shower was used as a battering ram to smash through a window.
A floor was also flooded.
CBC News was told the ruckus might have been fuelled by jail-house liquor.
A source said prisoners are given fruit and sugar with meals. Some inmates hide the items, allowing the fruit and sugar to ferment into liquor.
The trial is set to begin on March 20.
