The Lord Warden was solely responsible for the return of all writs to the Crown, along with the collection of taxes and the arrest of criminals. His court was held in St James's church, near Dover Castle, and there he exercised jurisdiction broadly equivalent to that of Chancery. He also had a "lieutenant's powers of muster", and the Constableship of Dover Castle, later added (1267) to the warden's office, enabled him to keep a garrison and administrative staff, including the clerk and the lieutenant of the castle.
