Devolved, reserved and excepted matters

In the United Kingdom, devolved matters are the areas of public policy where the Parliament of the United Kingdom has devolved its legislative power to the national legislatures of Scotland, Wales and Northern Ireland, while reserved matters and excepted matters are the areas where the UK Parliament retains exclusive power to legislate.

The devolved administrations in Scotland, Wales and Northern Ireland have been granted power by the Parliament under their respective legislators in all areas except those which are reserved (or excepted in the case of Northern Ireland). Because the Parliament acts with sovereign supremacy, it is still able to pass legislation for all parts of the United Kingdom, including in relation to devolved matters.
