A self-governing colony is a colony with an elected government in which elected rulers are able to make most decisions without referring to the colonial power with nominal control of the colony. Most self-governing colonies have responsible government.
Self-governing colonies for the most part have no formal authority over constitutional matters such the monarchy and the constitutional relationship with Britain. The Judicial Committee of the Privy Council, in London, serves as the ultimate avenue of appeal in matters of law and justice.
Colonies have sometimes been referred to as "self-governing" in situations where the executive has been under the control of neither the imperial government nor a local legislature elected by universal suffrage, but by a local oligarchy state. In most cases such control has been exercised by an elite class from a settler community.
The term "self-governing colony" has sometimes been used in relation to the direct rule of a Crown colony by an executive governor, elected under a limited franchise, such as in Massachusetts between 1630 and 1684.
The first local legislatures raised in England's colonies were the House of Burgesses of Virginia (1619) and the House of Assembly of Bermuda (1620), originally part of Viachieve responsible government in January–February 1848 through the efforts of Joseph Howe, followed by the Province of Canada later that year. They were followed by Prince Edward Island in 1851, New Brunswick, and Newfoundland in 1855 under Philip Francis Little. The Canadian colonies were federated as a Dominion in 1867, except for Newfoundland, which remained a separate self-governing colony, was a separate Dominion in 1907-1934, reverted to being a crown colony in 1934, and joined Canada in 1949. However, the term "self-governing colony" is not widely used by Canadian constitutional experts.
