Committee of Enquiry
From Tardis Wiki, the free Doctor Who reference
The Committee of Enquiry was an organization that existed among the Time Lords' government on Gallifrey.
During the reign of Morbius, the Committee was chaired by Junior-Cardinal Borusa which investigated Morbius's activities. It was discovered that he had supporters even within the Celestial Intervention Agency. (PDA: Warmonger)
It is possible that the jury, the Inquisitor and the Valeyard present at the Sixth Doctor's trial during the Trial of a Time Lord arc, could be considered a Committee of Enquiry for that particular trial.
