Background
The Supreme Court of the United Kingdom is the final court of appeal for all UK civil cases and for criminal cases from England, Wales, and Northern Ireland. It was established on 1 October 2009 under the Constitutional Reform Act 2005, taking over the judicial functions previously exercised by the Appellate Committee of the House of Lords (the Law Lords). It sits in the former Middlesex Guildhall on Parliament Square, opposite the Houses of Parliament.
The Supreme Court sits above the Court of Appeal in the judicial hierarchy. The Divisional Court (a High Court configuration for judicial review) sits below the Court of Appeal, meaning most judicial-review cases end at the Divisional Court or Court of Appeal, with only those on points of general public importance reaching the Supreme Court. Reform UK's February 2026 challenge to the election postponement was scheduled for Divisional Court hearing; had the government not withdrawn the policy, any adverse ruling could eventually have reached the Supreme Court on appeal.
