Originally, the House of Assembly was the only house in the legislature. It held its first session in 1620, making Bermuda's Parliament amongst the world's oldest legislatures. An appointed Privy Council originally performed roles similar to those of an upper house and of a cabinet.
A major constitutional change took place in 1968. The Privy Council was replaced with an appointed Senate and a Cabinet composed of Members of Parliament from the party with the most seats in the House of Assembly. Political parties were legalised, and universal adult suffrage adopted. The position of Premier was also introduced as leader of the ruling party, and an official opposition.
1 "Bailiwick-wide" legislation passed in the States of Guernsey applies not only in Guernsey, but also in Alderney and Sark, with the consent of their governments.
2 Although Island Councils for Ascension and Tristan da Cunha exist, they are purely consultative. Legislation is enacted by the Governor, although this power is normally exercised on their behalf by an Administrator.
