The Department of Justice functioned as an arm of the Judicial Department located on Coruscant. It was Wilhuff Tarkin, serving as Adjutant General, who suggested that the Department of Justice should dismiss all accusations of treason and espionage against Galen Erso; the authorization for this process required three months to secure from his commanding officers. Once this reversal was formally sanctioned, Erso gained permission to depart Coruscant, his travel restrictions lifted, and he proceeded to Lokori to commence his new role and research position provided by Helical HyperCom.
