Judicial Department / Legends The Judicial Department ( sometimes called the Judiciary or the Judiciary Department ) was the primary law enforcement agency for the Galactic Republic . Under the command of the Galactic Senate , it became a department of the Office of the Supreme Chancellor during the last decades of the Republic . Though the Judicials of the department , in general , served as law enforcement and later also as military forces , the department had specific agencies to provide police services . This included the Republic Office of Criminal Investigations ( ROCI ) , the Sector Ranger s ( officially under the ROCI ) , the Republic Security Force , and the Senate Guard . The ROCI was in charge of coordinating Republic criminal investigations and managed the Sector Rangers , one of the earliest law enforcement agencies in Republic service . The Republic Security Force was composed of uniformed police officers called Republic Peace Officer s . It provided basic law enforcement services to Republic worlds including emergency response , traffic control , apprehending criminals and conducting raids . Though officially a part of the Judicial Department , the Senate Guard mostly acted independently . After the Ruusan Reformation the department was drastically reorganized and its responsibility were expanded . Notably , the Judicial Department was placed in charge of supervising the Jedi Order . Also , the remaining forces of the Army of Light were reorganized as the Judicial Forces , the only form of a standing military the Republic would have for the next thousand years . With the coming of the Clone Wars between the Republic and Confederacy of Independent Systems , the Judicial Forces ' navy and ground units were merged into the re - established Republic Navy and Grand Army of the Republic , respectively . The Jedi Order similarly became a part of the military command structure . With these changes , the Judicial Department focused solely on law enforcement duties until it was dissolved with the formation of the Galactic Empire . Description . Duties and departments . The Judicial Department was the primary law enforcement agency for the Galactic Republic . Headquartered in the Judicial Arcology on the planet Coruscant , the Judicial Department was responsible for policing the Republic ' s space and investigating criminal activities . To accomplish this , the department managed several agencies with specific law enforcement duties . This included the Republic Office of Criminal Investigations ( ROCI ) , the Sector Ranger s ( officially under the ROCI ) , the Republic Security Force , and the Senate Guard . The ROCI was charged with coordinating investigations by law enforcement agencies of criminal activities . They also supervised the Sector Rangers . The Rangers were one of the earliest law enforcement agencies in Republic service and though officers were assigned on a sector level , the Rangers had Republic wide jurisdiction and were usually sent to investigate organized crime . The Republic Security Force , also called the Republic Guard , was composed of uniformed police officers called Republic Peace Officer s . Republic Security provided basic law enforcement services to Republic worlds that requested them including responding to emergency calls , controlling traffic , apprehending criminals and , when needed , conducting raids . The Senate Guard , though an official branch of the Judicial Department , mostly worked independently and ultimately answered to the Senate Guard Committee . Organizational structure . The Judicial Department was a part of the Office of the Supreme Chancellor and led by the Supreme Chancellor . Members of the department including police officers and other officials were referred to as Judicials . The Director of Investigation was in overall command of investigations conducted by the Judicial Department . The Director of Personnel was in charge of recruiting new Judicial members . In regards to press relations , the position of Information Director was responsible for notifying the public of Judicial activities and to give statements . For the prosecution of cases , the department had several General Attorneys and their assistants . Sector Coordinator s were in charge of Judicial operations within their assigned sector . For those that sought service within the Judicial Department , most graduated from the Judicial Academy though others also entered the Raithal Academy and the Academy of Carida History . It existed as far back as the Indecta Era , when it developed assassin droid technology . After the Russan Reformation , the Republic Military was reorganized as the Judicial Forces and placed under the command of the Judicial Department . Along with the Republic Outland Regions Security Force and the Republic Special Task Force they patrolled Republic space and assisted the Jedi when extra military force was required . The Russan Reformation also placed the Jedi Order under the supervision of the Judicial department . Following the disastrous Eriadu Trade Summit , the Senate passed restrictions on the Judicial Department , limiting the cases in which the Chancellor could use it without first gaining explicit approval from the Senate . These restrictions were presumably lifted sometime during the administration / reign of Palpatine . During the Dorvalla incident in 33 BBY , the Judicial Department requested a meeting with Supreme Chancellor Finis Valorum and later informed him of the hostilities that emerged between the Trade Federation and the Nebula Front . They were later deployed to deal with the crisis before it escalated . In 21 . 5 BBY , the Judicial Department was involved in an ongoing investigation of the Haruun Kal government in order to determine their treatment of the native Korun . However , the planet instead decided to escape any persecution by joining hands with the Confederacy of Independent Systems during the Clone Wars . The Judiciary was later involved in questioning rogue Givin saboteur Gavrilonnis Tejere before he could complete his work on Coruscant . After being processed , Grand Master Yoda revealed to the HoloNet that Tejere had no connection to the Separatists . Judicial Forces did not reveal their questioning of the suspect after he was brought into custody by Jedi Master Yoda and Mace Windu . The investigation of the Givin saboteur was later a joint venture between the Judiciary and Senate Bureau of Intelligence agents as well as overseen by Jedi Knight Qu Rhan . At another point , the Department was involved in a joint investigation with the Jedi Order over the possibility of Stone Mite s being a genetically engineered weapon deployed on worlds after the planet Ord Tiddell suffered from a devastation infestation of the insects . They along with the Jedi Order also worked in concert to battle the threat of the Pirates of Iridium in the Atrivis sector . In the resultant skirmish , four Republic Judiciaries along with two Jedi Knights were killed over the gas giant Vuchelle . This was later revealed to the news network by the Judicial Department who highlighted the victory over the pirate forces of Iridium . The department also denied the attempts by the People ' s Inquest to reveal the budget of the Jedi Order . With the formation of the Galactic Empire , the Judicial Department was dissolved and its responsibilities were given to other agencies .
