Galactic Courts of Justice Building
From Wookieepedia, the Star Wars wiki.
The Galactic Courts of Justice Building, usually referred to just as the Courts Building, was the headquarters for the judicial branch of the Old Republic's government, and housed the Supreme Court, and possibly the lesser Regional Courts as well. It was the same in the Empire for a time.
It was located in the Plains of Coruscant, near Bail Antilles' favorite restaurant.
Most likely the Court of Justice was housed in this same building alongside the ressurected Regional Courts.
