Section 172(2) of the Constitution does not oblige the Constitutional Court to determine all appeals or confirmations of orders of constitutional invalidity brought before it. At least where a provision declared invalid by a High Court has subsequently been repealed by an Act of Parliament, the Court has discretion to decide whether to deal with the matter. In exercising this discretion, the Court should consider whether any order it may make will have any practical effect either on the parties or on others. Where new legislation replaces all relevant aspects of the legislative framework upon which a dispute was based, and the basis upon which parties approached the High Court has disappeared, the grant of relief and confirmation of constitutional invalidity can serve no purpose. In such circumstances, the Court may decline to hear the matter. As a general principle, an order of invalidity should have no effect on cases which have been finalized prior to the date of the order of invalidity, in the interests of justice, good government, avoiding dislocation to the administration of justice, and ensuring a smooth transition.
