Kekere-Ekun JSC in the case of James v INEC Supra, at Page 583-584 Para H-A: “…it is clear that where a court lacks jurisdiction to entertain a cause or matter, it lacks jurisdiction to determine any issue arising within that cause or matter. To attempt to do so would amount to delving into the merit of the case, which would amount to a nullity in the event that the court lacks jurisdiction to determine the suit.”
FEDERAL HIGH COURT HAS JURISDICTION IN MATTERS OF FEDERAL GOVERNMENT AGENCY
The very fact that the operation and interpretation of the provisions of the Constitution affecting the powers and functions of a Federal Government agency is the main subject of this case, the 1st Respondent, the Honourable Attorney General of the Federation as the Chief Law Officer of the entire Federation appointed under Section 150 of the same Constitution, who is therefore not only the guardian of the Constitution but also the protector of the same, the Appellant’s action which sought to protect the violation of the provisions of the Constitution, is certainly not only regarded as an action against the National Judicial Council whose powers and functions were subject of the violation but also against the Honourable Attorney General of the Federation whose role in protecting the provisions of the Constitution from being violated, was in issue in the case. These features of this case are what brought the case within the jurisdiction of the Federal High Court.
