The Appellate Jurisdiction Act 1876 (39 & 40 Vict. c. 59) was an Act of the Parliament of the United Kingdom that altered the judicial functions of the House of Lords by allowing senior judges to sit in the House of Lords as life peers with the rank of baron, known as Lords of Appeal in Ordinary. The first person to be made a law lord under its terms was Sir Colin Blackburn on 16 October 1876, who became Baron Blackburn. The Act was repealed by the Constitutional Reform Act 2005, which transferred the judicial functions from the House of Lords to the Supreme Court of the United Kingdom. Following the creation of the Supreme Court of the United Kingdom, the practice of appointing Lords of Appeal in Ordinary was discontinued. The last person to be made a law lord was Sir Brian Kerr on 29 June 2009, who became Baron Kerr of Tonaghmore.
