1. If any person alleges that any of the provisions of sections 3 to 17 (inclusive)⁴ of this Constitution has been, is being or is likely to be contravened in relation to him (or, in the case of a person who is detained, if any other person alleges such a contravention in relation to the detained person), then, without prejudice to any other action with respect to the same matter that is lawfully available, that person (or that other person) may apply to the High Court for redress.
2. The High Court shall have original jurisdiction-
a. to hear and determine any application made by any person in pursuance of subsection (1) of this section; and
b. to determine any question arising in the case of any person that is referred to it in pursuance of subsection (3) of this section,
and may make such declaration and orders, issue such writs and give such directions as it may consider appropriate for the purpose of enforcing or securing the enforcement of any of the provisions of sections 3 to 17 (inclusive) of this Constitution:
Provided that the High Court may decline to exercise its powers under this subsection if it is satisfied that adequate means of redress for the contravention alleges are or have been available to the person concerned under any other law.
3. If in any proceedings in any court (other than the Court of Appeal, the High Court or a court-martial) any question arises as to the contravention of any of the provisions of sections 3 to 17 (inclusive) of this Constitution, the person presiding in that court may, and shall if any party to the proceedings so requests, refer the question to the High Court unless, in his opinion, the raising of the question is merely frivolous or vexatious.
4. Where any question is referred to the High Court in pursuance of subsection (3) of this section, the High Court shall give its decision upon the question and the court in which the question arose shall dispose of the case in accordance with that decision or, if that decision is the subject of an appeal to the Court of Appeal or to Her Majesty in Council, in accordance with the decision of the Court of Appeal or, as the case may be, of Her Majesty in Council.
5. There shall be such provision as may be made by Parliament for conferring upon the High Court such powers in addition to those conferred by this section as may appear to be necessary or desirable for the purpose of enabling that court more effectively to exercise the jurisdiction conferred upon it by this section.
