On 1 October 2009, the Appellate Jurisdiction Act 1876 was repealed by Schedule 18 to the Constitutional Reform Act 2005[1][2] owing to the creation of the Supreme Court of the United Kingdom.
On 1 October 2009, the Lords Appeal in Ordinary became the first Justices of the Supreme Court of the United Kingdom.
Those appointees who were not already members of the House of Lords were created life peers; for their titles see above.
Initially it was intended that peers created in this way would only sit in the House of Lords while serving their term as judges, but in 1887 (on the retirement of Lord Blackburn) the Appellate Jurisdiction Act 1887 provided that former judges would retain their seats for life.
Under the terms of the Constitutional Reform Act 2005, which transferred the judicial functions of the House of Lords to the new Supreme Court, previous Law Lords who were transferred to the Supreme Court do not have the right to speak and vote in the House until they leave office.
