It is crystal clear that the question involved in issue 2 for the determination of this court is entirely constitutional. A constitutional issue, like the question of jurisdiction, is not only fundamental but must be disposed of by the court as soon as it is raised to ensure that the proceedings in which it is raised is not rendered nugatory and null and void and that the Constitution which is the supreme law of the land is not breached. See Alhaji Rufai Agbaje and others v. Mrs. W.A. Adelekan and others (1990) 7 NWLR (Pt. 164) 595 at 614. It is in the interest of the best administration of justice that where the issue of jurisdiction or a constitutional issue is raised in any proceedings before any court, it should be dealt with at the earliest opportunity and before a consideration of any other issues raised in the proceedings as anything purportedly done without or in excess of jurisdiction or in breach of the Constitution, which is the supreme law of the land, by any court established under the said Constitution is a nullity and of no effect whatever. See On venta and others v. Oputa and others (1987) 3 NWLR (Pt.60) 259; (1987) 2 N.S.C.C. 900; Attorney General of the Federation and others v. Sode and other (1990) 1 NWLR (Pt. 128) 500; (1990) I N.S.C.C. 271; Tukur v. Government of Gongola State (1989) 4 NWLR (Pt. 117) 517 at 545 etc. Accordingly, I will proceed firstly to examine issue 2 which raises a grave constitutional question in this appeal.
