I have found that ground (1) is premised on the jurisdiction of the lower court. It is the law that even where a court of law does not pronounce whether it has jurisdiction to try a matter or not, once the establishing law or other statutes or the subject matter or party before the court has divested that court of jurisdiction, then jurisdiction does not reside in the court. The ground is properly taken by the appellant in this appeal as issue of jurisdiction can be raised at any level of the proceedings of a court even at appeal levels. See: Nigeria Eng. Works Ltd. v. Denap Ltd. (2001) 18 NWLR (Pt.746) 726.
