Lords of Appeal in Ordinary
Until the formal opening of the Supreme Court of the United Kingdom on 1 October 2009, life peers created under the Appellate Jurisdiction Act were known as "Lords of Appeal in Ordinary" or in common parlance "Law Lords". They performed the judicial functions of the House of Lords and served on the Judicial Committee of the Privy Council. They remained peers for life, but ceased to receive judicial salaries at the age of 75. Under the terms of the Act, there may be no more than 12 Lords of Appeal in Ordinary under the age of 75 at one time. However, after the transfer of the judicial functions of the Lords to the Supreme Court of the United Kingdom, the Act ceased to have meaningful effect.
