The trial in 2373 of the Voth scientist Forra Gegen, who was charged with heresy for arguing that his saurian people had evolved on Earth and not in the Delta Quadrant.
The Voth heresy trial of Gegen takes place in the Voyager episode Distant Origin. Gegen, a palaeontologist, finds the remains of a Voyager crewman on a planet the ship visited and sees that the bones share genetic markers with his own species. He and his assistant Veer follow Voyager in search of proof.
After Gegen takes Chakotay aboard his ship, the two work together. The evidence shows that the Voth are descended from Earth's hadrosaurs and left the planet tens of millions of years ago. Voth Doctrine holds that they were the first intelligent race of their own region, and a huge city ship seizes Voyager.
Before Minister Odala, Chakotay argues that such a journey is something to be proud of. Odala is unmoved, and she threatens to send Voyager's crew to a detention colony. To save them Gegen withdraws his theory and is transferred to another field. Chakotay leaves him a globe of Earth.
