The Supreme Court is to overhaul the way it appoints its justices, offering part-time posts and the use of positive action to assist unrepresented groups such as women and ethnic minorities. The changes come as a record six justices – half the Bench – are set to retire within the next two years. Those leaving include the president of the Supreme Court, Lord Neuberger, who will stand down by the end of next year and whose position is predicted to be taken by Baroness Hale, the court’s deputy president.
