Lordrichter
The number of Lords of Appeal in Ordinary (excluding those who were no longer able to hear cases because of age restrictions) was limited to twelve, but could be changed by statutory instrument. By a convention of the House, Lords of Appeal in Ordinary did not take part in debates on new legislation, so as to maintain judicial independence. Lords of Appeal in Ordinary held their seats in the House of Lords for life, remaining as members even after reaching the judicial retirement age of 70 or 75. Former Lord Chancellors and holders of other high judicial office could also sit as Law Lords under the Appellate Jurisdiction Act, although in practice this right was only rarely exercised.
