The Supreme Court was the highest court of law in the Galactic Republic. The Court, headquartered in the Galactic Courts of Justice Building on Coruscant, consisted of twelve judges. The Chief Justice, one of the twelve, was the head of both the court and the entire judicial branch of government. The Supreme Chancellor nominated candidates for the court who were then approved or denied by the Galactic Senate.
The Supreme Court was described as the court of last resort; it was the last and highest court of appeals, and it determined constitutional legality. The Supreme Court, however, would also preside over cases involving high ranking politicians and other individuals of note in the Republic. Some cases, such as treason by Galactic Senators or impeachment trials, were handled by the Senate, as the Senate considered them internal affairs that should have been handled from within.
