The form of Massachusetts government is provied by the Constitution of the Commonwealth. The legislative power is exercised by the bicameral General Court, which is composed of the Senate and House of Representatives. The executive power generally is exercised by the Governor, although only after receiving the advice and consent of the Governor's Council with respect to certain subjects. Several other officers, including the Attorney General and Secretary of the Commonwealth, perform executive functions and are elected independently. The judicial power is reposed in the Supreme Judicial Court, which superintends the entire system of courts. Cities and towns also act through local governmental bodies that possess only the authority granted to them by the Commonwealth over local issues, including limited home rule authority. Most county governments were abolished in the 1990s, although a handful remain.
