High Council

The High Council, sometimes called the Supreme Council or High Council of Time Lords, was the governing body of the Time Lords on Gallifrey, composed of the Lord President and advisers from the ruling Houses.

Officially, without a President, the Council could ratify nothing, even if this occurred in exceptional cases such as the absence of the President-elect. (TV: The Invasion of Time)

The Council was composed of Cardinals representing the Chapters of Gallifrey. Its members were elected. (TV: The Ultimate Foe)

By time of the Last Great Time War, the Time Lords had resurrected Rassilon, who returned to lead the High Council against the Daleks. At least an emergency session of the council was arranged, when the War Doctor and his companion Cinder landed on Gallifrey, bringing news about the Temporal Cannon of the Daleks. It was the first time a human had been allowed to attend such a meeting. (PROSE: Engines of War)

By the last day of the war, the High Council met in a darkened chamber in the ruined Citadel. They met there on the last day of the war to discuss Rassilon's Final Sanction. (TV: The End of Time)

After the Twelfth Doctor returned to Gallifrey, by this point hidden at the end of the universe, Rassilon sent them out to meet the Doctor who merely walked back inside the barn he had slept in as a child.
