House of Lords Speaker be a member of the House of Lords (though the same has long been customary). Whilst presiding over the House of Lords, the Lord Chancellor traditionally wore ceremonial black and gold robes. Robes of black and gold are now worn by the Lord Chancellor and Secretary of State for Justice in the House of Commons, on ceremonial occasions. This is no longer a requirement for the Lord Speaker except for State occasions outside of the chamber. The Speaker or Deputy Speaker sits on the Woolsack, a large red seat stuffed with wool, at the front of the Lords Chamber.
Judicial functions of the House of Lords continued to come before the House of Lords in a similar manner. An Appellate Committee, normally consisting of five Lords of Appeal in Ordinary or Lords of Appeal, heard the actual appeals. The minimum number of Law Lords that could form a Committee was four. Seven Lords could sit in particularly important cases. On 4 October 2004 a Committee of nine Lords, including both the Senior Law Lord Lord Bingham of Cornhill and Second Senior Law Lord Lord Nicholls of Birkenhead, was convened to hear challenges to the indefinite detention of suspects under the Anti-terrorism, Crime and Security Act 2001,
