Although, unlike the 1979 Constitution, Section 318(1) of the present Constitution does not define “High Court”, there is no doubt that the term carries the same meaning as given by Section 277(1) of the 1979 Constitution to mean Federal High Court or the High Court of a State. Therefore, it is my understanding that where a person’s fundamental right is breached, being breached or about to be breached, that person may apply under section 46(1) to the Judicial division of the Federal High Court in the State or the High Court of the State or that of the Federal Capital Territory in which the breach occurred or is occurring or about to occur. This is irrespective of whether the right involved comes within the legislative competence of the Federation or the State or the Federal Capital Territory, See the case of Minister of Internal Affairs v. Shugaba (1982) 3 NCLR 915. It has to however be noted that the exercise of this jurisdiction by the Federal High Court is where the fundamental right threatened or breached falls within the enumerated matters on which that court has jurisdiction. Thus, fundamental rights arising from matters outside its jurisdiction cannot be enforced by the Federal High Court. See: Tukur v. Government of Gongola State (1989) 3 NSCC 225. Equally, a High Court of a State shall lack jurisdiction to entertain matters of fundamental rights, although brought pursuant to section 46(2) of the Constitution where the alleged breach of such matters arose from a transaction or subject matter which fall within the exclusive jurisdiction of the Federal High Court as provided by Section 251 of the Constitution.
