Chief Public Prosecutor
From Gineipaedia, the Legend of Galactic Heroes wiki
The Chief Public Prosecutor would have been the chief prosecution officer in the Free Planets Alliance' judicial system: he or she would have been in charge of prosecuting criminals in the highest courts of the Alliance, as well as overseeing the actions of many subordinate prosecutors. It is unknown whether the Chief Public Prosecutor was a local (city), regional (planet), or national (the entire Alliance) office. (LOGH: 'Invitation to an Opera')
