The Executive Council is the senior decision-making body and executive branch of the Government of the Principality; however, as it is made up partially of officers of the Legislative Assembly and high-ranking members of the Judicature, among others, the various branches of government can be said to overlap in the Council.

Members of the Executive Council are selected by the Prince in accordance with procedures described in the Constitution. The Executive Council is responsible for the day-to-day administration of the Government. In this role, its members work with the various branches of Government, with other Councilors, or as individuals. The Reigning Prince, who is himself a member of the Executive Council, cannot retreat from Council without risking having his powers suspended by a Regency.
