High Court of the Time Lords

By some accounts, the High Court of the Time Lords was a powerful Time Lord institution which held the Doctor's first trial. (PROSE: The Trial of Doctor Who, Doctor Who and the Auton Invasion, World Game) Other sources gave different names for the court which filled this role. (TV: The Deadly Assassin, PROSE: Doctor Who and the Doomsday Weapon, Doctor Who and the Terror of the Autons, et al.) By some accounts, the High Court was overseen by the President, (PROSE: Doctor Who and the Auton Invasion, World Game) matching a slightly different's reference to the "High Tribunal" as headed by the First Time Lord, the highest-ranking member of Time Lord society. (PROSE: Doctor Who and the Doomsday Weapon)

Drax once remarked to the Fourth Doctor that he had heard about the High Court exiling the Doctor to Earth. (PROSE: Doctor Who and the Armageddon Factor)

The Sixth Doctor once made reference to the High Courts of Gallifrey. (PROSE: Revelation of the Daleks)
