Devolution is the granting of powers to a lower level of government, while preserving sovereignty to the granting level. Unlike the federal arrangements of countries such as the United States of America, devolution reserves supreme power to the granting level.
In other words, the granting level (the United Kingdom Parliament) can pass legislation which overrides legislation of the lower level (the Scottish Parliament) and it can even withdraw those powers at any time.
Former schemes of devolution in the United Kingdom:
- the Government of Ireland Act, 1920 - suspended in 1972
- the Scotland and Wales Acts, 1978 - both were rejected in referenda
Schemes of devolution which are implemented at present:
- The Belfast Agreement, also known as the ‘Good Friday’ Agreement for Northern Ireland, 1998
- the Scotland Act, 1998
- the Wales Act, 1998
