High Tribunal

The High Tribunal of Gallifrey put the Doctor on trial on at least one occasion.

By some accounts, the court who placed the Second Doctor on trial was the High Tribunal. (PROSE: Doctor Who and the Doomsday Weapon, The Quantum Archangel) One account specified that it consisted of the First Time Lord, Second Time Lord, and Third Time Lord, the three highest-ranking members of Time Lord society. (PROSE: Doctor Who and the Doomsday Weapon)

Another account noted that the High Tribunal was also behind the trial of the Sixth Doctor. (PROSE: Synthespians™, The Quantum Archangel)
