Devolution is the statutory granting of powers from the central government of a Sovereign state to government at a subnational level, such as a
regional, local, or state level. It differs from
federalism in that the powers devolved may be temporary and ultimately reside in central government, thus the state remains,
de jure,
unitary.
Any devolved parliaments or assemblies can be repealed by central government in the same way an ordinary statute can be. Federal systems, or federacies, differ in that state or provincial government is guaranteed in the constitution. Australia, Canada and the United States have federal systems, and have constitutions (as do some of their constituent states or provinces). They also have Territories, with less power and authority than a state or province.
The devolution can be mainly financial, e.g. giving areas a budget which was formerly administered by central government. However, the power to make legislation relevant to the area may also be granted.
In the United Kingdom, devolved government was created following simple majority referenda in Wales and Scotland in September 1997. In 1998, the Scottish Parliament, National Assembly for Wales and Northern Ireland Assembly were established by law. The move came eighteen years after similar proposals were defeated in qualified majority referendums in Wales and Scotland in March 1979, though in Scotland's case a slim majority of those voting had backed the proposal.
