The Supreme Court is the highest and final court of appeal for all United Kingdom civil cases, and criminal cases from England, Wales and Northern Ireland. Formed in October 2009, it replaced the Appellate Committee of the House of Lords as the highest court in the UK. At the time of writing, it has heard over 835 appeals and hears cases of the greatest public or constitutional importance. The building is located on Parliament Square, just opposite Big Ben and the Houses of Parliament.
The judges of the Supreme Court, known as Justices, have the final say on the biggest legal issues. For example, the Court recently heard the high-profile Brexit prorogation-related judicial review case of R (Miller) v The Prime Minister which sought to investigate the legality of the prorogation of parliament in Summer 2019.
