The Government of Wales, since 1998, composed of the Welsh National Assembly and the Welsh Assembly Government.
But judicially it remains within part of the jurisdiction of England and Wales, although the Welsh National Assembly was given the rights to enact Wales-specific Measures, and, with the Welsh devolution referendum, 2011, the Welsh National Assembly will be given the power to enact Acts.
Wales, together with Cheshire, used to have Court of Grand Session, and therefore not within the English circuit court system. Yet it has never been its own jurisdiction.
Before 1998, there was no separate government in Wales. Executive authority rested in the hands of the HM Government, with substantial authority within the Welsh Office since 1965. Legislative power rested within the Parliament of the United Kingdom. Judicial power has always been with the Courts of England and Wales, and the Supreme Court of the United Kingdom (or its predecessor the Law Lords).
