In Kakih v PDP (2014) 15 NWLR (Pt.1430) p.374, in support of N.E.P.A. v Edegbero supra. I said that: “The claim of the party and the reliefs must be within Section 251 (1) of the Constitution before the Federal High Court can have jurisdiction. Furthermore, where an agency of Federal Government is a party, the principal reliefs must be directed against the Federal Government or any of its agencies before a Federal High Court can have jurisdiction.”
JURISDICTION IS FUNDAMENTAL TO ADJUDICATION
Jurisdiction, it is settled, is fundamental to adjudication. It is a radical and crucial necessity for, as in the instant case, where a Court proceeds without jurisdiction to hear the case, the proceedings so embarked upon by the Court are a nulity ab initio however well conducted the proceedings and brilliantly decided the issues agitated therein are. Defect in the Court’s competence is intrinsic and not extrinsic to the entire adjudicatory process. See Oloriode V. Oyebi (1984) 5 SC 1 at 32 33, Mustapha V, Governor of Lagos State and Musaconi Limited V. Mr. H, Aspinall (2013) LPELR 20745 (SC). It must be restated that a Court is only vested with jurisdiction and power to adjudicate on an issue when the matter is brought before it in accordance with both substantive and adjectival law. See Madukolu V. Nkemdilim (1962) SCNLR 341, Ukwu V. Bunge (1997) 8 NWLR (Pt 678) 527.
