Jurisdiction (High Court of the FCT)
Section 257(1) · 1999 Constitution (2004 edition)
What Constitution says
(1) Subject to the provisions of section 251 and any other provisions of this Constitution and in addition to such other jurisdiction as may be conferred upon it by law, the High Court of the Federal Capital Territory, Abuja shall have jurisdiction to hear and determine any civil proceedings in which the existence or extent of a legal right, power, duty, liability privilege, interest, obligation or claim is in issue or to hear and determine any criminal proceedings involving or relating to any penalty, forfeiture, punishment or other liability in respect of an offence committed by any person.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
