This issue reminds of the dictum of this Court in Sodipo v Lemminkainem OY and Anor[1986] 1 NWLR (pt. 15) 220, According to the Court: “A Judge exists to determine disputes and examine with due care and microscopic senses all matters before him in his pursuit of justice.” This dictum, to my mind, is a complete answer to the criticism by the appellants to the way and manner the learned trial Judge resolved the preliminary objection. In the first place, the question of no “live issue” found in the suit, was not raised by any of the parties in arguing the preliminary objection. A trial Judge, however, is within his rights to properly inform himself of a defect in a suit, either with or without external intervention, because it touches directly on the competence of the suit and hence the jurisdiction to entertain it as such. Thus, the established principle that the issue of jurisdiction can be raised at any stage of the proceedings, at the instance of either the parties or by the Court suo motu, Amale v. Sokoto Local Govt and Ors. [2012] 1 SC (pt. IV) 45; Odiase v. Agho [1972] 1 All NLR (pt.1) 170; Petrojessica Entreprises Ltd v. Leventis Technical Co. Ltd, [1992] 2 NWLR (pt. 244) 675. Where however, the issue of jurisdiction is raised, it should be examined in all ramifications. It should not be compartmentalized and subjected to piecemeal examination and treatment, Oloba v Akereja [1988] 3 NWLR (pt. 84) 508. The very many faces of jurisdiction should come under the searchlight and be pronounced upon, notwithstanding that it might not have been brought to the attention of the Court.
