Public duties in the context of "Household Division"

Two Sheriffs of the City of London are elected annually by the members of the City livery companies. Today's Sheriffs have only ceremonial duties, but the historical officeholders held important judicial responsibilities. They have attended the justices at the Central Criminal Court, Old Bailey, since its original role as the court for the City and Middlesex.

The Sheriffs reside at the Old Bailey during their year of service, so that one of them can always be attendant on the judges. In Court No. 1 the bench's principal chairs are reserved for their and the Lord Mayor's use, with the Sword of the City hanging behind the bench. It is an invariable custom that the Lord Mayor of London must previously have served as Sheriff. To become a Sheriff, one must be lawfully entitled to armorial bearings by proving their right by descent, whilst those not armigerous by birth can apply for a grant from the College of Arms to run for office.

Foot guards are senior infantry regiments within the British Army and the Canadian Army whose primary role includes military and combat operations, while its secondary role include public duties responsibilities which reflect their senior status. Foot guards regiments were historically infantry soldiers who fought on foot who also performed public duties like mounting a guard.

The British foot guards were established in the 17th century, and served as an infantry unit and royal guards for the monarchy. In the 19th century, the Canadian foot guard were formed, modelled after their British counterparts as a reflection of Canada’s relationship with the monarchy and to undertake ceremonial duties in Ottawa. Historically, other countries have also maintained units called "foot guards," though not all of these were the senior infantry regiments of their forces or were units that were tasked with both military combat responsibilities and ceremonial public duties.
