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.
JURISDICTION IS DETERMINED FROM THE FACTS PRESENTED BY THE PLAINTIFF
Para. 12: “The plaintiffs failed to address the issues raised by the defendant in the preliminary objection. This court in its inherent jurisdiction to do justice at all times will however proceed to analyze the issues raised in line with the facts presented by the plaintiffs in the initiating application. This is more so as jurisdiction is determined from the facts presented in a Plaintiffs application and not from the defence.”
