The High Court consists of the Chief Justice of Singapore and the Judges of the High Court. A person is qualified to be appointed a Judge if he or she has for an aggregate period of not less than ten years been a qualified person within the meaning of the Legal Profession Act or a member of the Singapore Legal Service, or both. The Chief Justice and Judges of the High Court are appointed by the President of Singapore if he, acting in his discretion, concurs with the advice of the Prime Minister. Where the appointment of Judges is concerned, the Prime Minister is required to consult the Chief Justice before tendering advice to the President. In addition, to facilitate the disposal of business in the Supreme Court, the President may, if he concurs with the Prime Minister's advice, appoint people qualified to be judges to be Judicial Commissioners of the Supreme Court. Judicial Commissioners exercise the same powers and perform the same functions as Judges of the High Court. However, unlike Judges who generally hold office until the age of 65 years, Judicial Commissioners do not have security of tenure.
