The Warden of the Fleet Prison, who was also keeper of Westminster Hall, was tasked with keeping it clean and letting the shops and booths along the sides. Despite acting as gaoler to the Exchequer of Pleas, Court of Chancery and Star Chamber as part of his duties the Warden was considered an officer of the Court of Common Pleas. All court officers were appointed for life, and could only be removed for misbehaviour. Despite this, the sheer number of positions meant that several came up for reappointment in each Chief Justice's tenure, and selling them could be very profitable.
