Generally, proceedings before the Court of law can be regarded as a nullity where:- (a) The Court is not properly constituted as regards numbers and qualifications of the members of the bench. (b) The subject-matter of the action is not within the jurisdiction of the Court. (c) The case before the Court is not initiated by due process of law, or that there is a condition precedent to the exercise of jurisdiction. See MADUKOLU V NKEMDILIM, (1962)1 ALL N.L.R 587. — M.L. Shuaibu, JCA. Ekpo v GTB (2018) – CA/C/324/2013
JURISDICTION CAN BE RAISED AT ANYTIME NOT APPLICABLE TO ARBITRATION
For instance, the general position of the law that the issue of jurisdiction of a Court can be raised at any stage of the proceedings of a case, even for the first time at the appellate stage, is not applicable to arbitral proceedings before an arbitral Tribunal because the Act, in Section 12(3) has provided the stage at which a challenge to the jurisdiction of the arbitral Tribunal is to or may be raised by a party.
