 Under the Constitutional Reform Act 2005, the Lords of Appeal in Ordinary when the Act came into effect in 2009 became judges of the new Supreme Court of the United Kingdom and were then barred from sitting or voting in the House of Lords until they had retired as judges.One of the main justifications for the new Supreme Court was to establish a separation of powers between the judiciary and the legislature.It is therefore unlikely that future appointees to the Supreme Court of the United Kingdom will be made Lords of Appeal in Ordinary.
