In A.G. Kwara State & Anor v Saka Adeyemo & Ors (2016) 7 SC (Pt.II) p. 149. I said that: Jurisdiction is a question of law. There are two types of jurisdiction. 1. Jurisdiction as a matter of procedural law. 2. Jurisdiction as a matter of substantive law. A litigant may waive the former. Again in Appeal No: SC.175/2005 Heritage Bank Ltd v Bentworth Finance (Nigeria) Ltd decided by this Court on 23 February, 2018 Eko J.S.C. explained the distinction between substantive jurisdiction and procedural jurisdiction.
NO JURISDICTION WHERE STATUTORY CONDITION NOT FULFILLED
After all, it is to be remembered that all appeals in this country and elsewhere exist merely by statute and unless the statutory conditions are fulfilled no jurisdiction is given to any Court of Justice to entertain them.
