The rule that precludes certain Crown officers from serving in the House of Commons is used to circumvent a resolution adopted by the House of Commons in 1623, under which members are not permitted to resign their seats. In practice, however, they always can. Should a member wish to resign from the Commons, she or he may request appointment to one of two ceremonial Crown offices: that of Crown Steward and Bailiff of the Chiltern Hundreds, or that of Crown Steward and Bailiff of the Manor of Northstead. These offices are sinecures (that is, they involve no actual duties); they exist solely to permit the "resignation" of members of the House of Commons. The Chancellor of the Exchequer is responsible for making the appointment, and, by convention, never refuses to do so when asked by a member who desires to leave the House of Commons.
