The new UK Supreme Court opened in October 2009. Only one member of the Court is a woman. Lady Brenda Hale was appointed to the predecessor of the Supreme Court, the Appellate Committee of the House of Lords in 2003, the first and only female Law Lord. An opportunity to appoint a second female Supreme Court Justice will arise when a current vacancy on the court is filled.
Biographies of the Justices can be found on the Supreme Court website.
