Jurisdiction (Federal High Court)
Section 251(1)(s) · 1999 Constitution (2004 edition)
What Constitution says
(s) such other jurisdiction civil or criminal and whether to the exclusion of any other court or not as may be conferred upon it by an Act of the National Assembly: Provided that nothing in the provisions of paragraphs (p), (q) and (r) of this subsection shall prevent a person from seeking redress against the Federal Government or any of its agencies in an action for damages, injunction or specific performance where the action is based on any enactment, law or equity.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
