Bürgerliches Gesetzbuch
Criminal and private laws are codified on the national level in the "Strafgesetzbuch" and the "Bürgerliches Gesetzbuch" respectively. The German penal system seeks the rehabilitation of the criminal and the protection of the public. Except for petty crimes, which are tried before a single professional judge, and serious political crimes, all charges are tried before mixed tribunals on which lay judges ("") sit side by side with professional judges.
