Without doubt, where a case is heard and judgment is delivered by a court without jurisdiction, the proceedings will be a nullity. – Iguh, JSC. Oshatoba v. Olujitan (2000)
THERE ARE TWO TYPES OF JURISDICTION
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.
