Law lord in the context of "Constitutional Reform Act 2005"

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.

Colin Blackburn, Baron Blackburn, PC (18 May 1813 – 8 January 1896) was a British lawyer and judge. The son of a Scottish clergyman, he was educated in Scotland and England, before joining the English bar. He was little known to the legal world before he was elevated from the junior bar to a puisne judgeship in the Court of Queen's Bench by Lord Campbell in 1859, a position he held until 1876, when he was appointed to the Court of Appeal. In October of that year, he was the first person to be appointed as a law lord under the provisions of the newly enacted Appellate Jurisdiction Act. He retired in 1886 and died ten years later.
