Oko v. State  17 NWLR (Pt. 1593) 24 at 65-66, paras. H-A, per Peter-Odili, JSC:
“Clearly, this partition or fragmentation of the jurisdictional question is one to which the appellant is estopped from embracing. It is all the more foreclosed as counsel had the time and opportunity of raising the issue of the lack of consent in the trial court and failed to do so. He lost his chance which he cannot call up as the fancy takes him.”
The pronouncement of the Supreme Court above is significant in addressing the practice of some counsel who might have observed some objectionable points touching on jurisdiction but would rather elect to raise the points piecemeal. That is to say, as a matter of tactics, counsel may observe 3 jurisdictional questions but would file a preliminary objection or motion raising one or two grounds only; leaving the third as a ‘spare bullet’ to be used (either at the court of first instance or on appeal) should the earlier application fail.
