Public Law analysis: Scotland—the Court of Session has refused a petitioner’s first plea in law, rendering their petition incompetent with regard to section 11A of the Tribunals, Courts and Enforcement Act 2007 (TCEA 2007) and refusing the petition. The petitioner sought to challenge the lawfulness of the restrictions on judicial review introduced by section 2 of the Judicial Review and Courts Act 2022 (JRACA 2022). The JRACA 2022 inserted section 11A into TCEA 2007, therefore removing judicial review as a route of challenge to a permission to appeal decision by the Upper Tribunal (UT) on the basis that such decisions are final and not liable to be questioned or set aside in another court. As a preliminary step, the petitioner sought a declaration that TCEA 2007, s 11A was unlawful, and separately null and void as well as seeking to overturn the UT’s decision of 5 September 2022 refusing permission to appeal. The petitioner argued that TCEA 2007, s 11A was unlawful firstly because the power to regulate judicial review procedure in Scotland is a devolved matter and secondly, because Parliamentary sovereignty was constrained by Article XIX of the 1707 Treaty of Union and by the common law. The Court held that the UK Parliament’s power to make laws for Scotland is unaffected by the Scotland Act 1988. It also held that TCEA 2007, s 11A was not inconsistent with the rule of law, nor that there was any conflict with Article XIX of the 1707 Treaty of Union.
