Can the UKSC overrule Devolved Parliaments and Assemblies in other parts of the UK?
The UKSC can hear ‘devolution issues’, which include questions about whether a Bill or Act of Parliament, or any provision of a Bill or Act of Parliament, would be within the legislative competence of the Scottish Parliament or of the Northern Ireland Assembly. Under the Government of Wales Act 2006, a question whether an Order in Council, Assembly Measure, Act of the Assembly or Bill is within the legislative competence of the Welsh Assembly can also be referred to the UKSC.
