The Republic Office of Criminal Investigations, also known as ROCI, functioned as a department within the Galactic Republic's Judicial Department. Its responsibilities included the administration of subsidiary law enforcement agencies and the upkeep of the Republic Enforcement DataCore. Regional judicial forces were supervised by ROCI sector coordinators, who also worked with local police to resolve possible conflicts of authority. In addition, ROCI collaborated with the Jedi Order when they were involved in formal Republic inquiries. The Republic Security Force along with the Sector Rangers were components that fell under the ROCI's jurisdiction. Later on, the Imperial Office of Criminal Investigations took its place.
