The members of the Senate elect a Supreme Chancellor from among their ranks who serves as the Senate's presiding officer and as the Republic's de facto leader. The Chancellor is assisted by the Vice Chair, who is presumably elected in the same manner as the Chancellor; the same Vice Chair is present throughout the entire prequel trilogy. The Senate follows pseudo-parliamentary rules. Supreme Chancellor Finis Valorum was forced out of office by the Senate in a motion of no confidence, introduced by Queen Padmé Amidala of Naboo, for example.
