 There is no formal constitutional structure for the lower level courts and tribunals, as these are established on a case by case basis by Parliament.The power of nominations of Justices throughout the Superior Courts of Judicature lies within the hands of the Chief Justice of the Supreme Court along with the power of approval by the President.The Supreme Court is composed of the Chief Justice and at least nine other Justices, but is able to hear cases with at least five Justices sitting at one time.
