Administrative Law in Nigeria

Introduction

Administrative law in Nigeria governs the exercise of public power by executive and administrative bodies. Rooted in English common law principles but shaped by the Constitution of the Federal Republic of Nigeria 1999 (as amended), Nigerian administrative law provides the legal framework for controlling governmental action, ensuring procedural fairness, and protecting citizens from arbitrary exercise of state power. The field encompasses judicial review through prerogative writs, the operation of administrative tribunals, and the evolving standards of natural justice applied by Nigerian courts.

Constitutional Foundations

Section 6 of the 1999 Constitution vests judicial powers in the courts, establishing the constitutional basis for judicial oversight of administrative action. The Constitution expressly provides for the enforcement of fundamental rights under Chapter IV and empowers the High Courts to exercise supervisory jurisdiction over inferior tribunals and administrative bodies. Section 46 specifically confers jurisdiction on the High Court to hear applications for the enforcement of fundamental rights, creating a conduit for challenging administrative action that infringes individual liberties.

Prerogative Writs and Remedies

The High Court of Justice (in each state and the Federal Capital Territory) exercises supervisory jurisdiction through the prerogative writs of certiorari, mandamus, prohibition, and habeas corpus, alongside the equitable remedy of injunction and declaratory judgments.

Certiorari

Certiorari lies to quash decisions of inferior courts, tribunals, or public authorities that are tainted by jurisdictional error, error of law on the face of the record, or breach of natural justice. In Okumagba v Egbe (1965) 1 All NLR 62, the Supreme Court affirmed that certiorari is available to correct errors of law apparent on the face of proceedings, regardless of whether the inferior court acted within its jurisdiction.

Mandamus

Mandamus compels a public officer or body to perform a statutory duty owed to the applicant. The Supreme Court held in State v Ilori (1983) 2 SCNLR 167 that mandamus will issue only where there is a clear legal duty and the applicant has made a prior demand for performance that was refused. The remedy is discretionary and will not be granted where an alternative remedy exists.

Prohibition

Prohibition restrains an inferior court or tribunal from acting outside its jurisdiction or in excess of its powers. Unlike certiorari, which quashes decisions already made, prohibition operates prospectively to prevent unlawful proceedings before their conclusion.

Habeas Corpus

Habeas corpus secures the release of persons unlawfully detained. Section 35 of the 1999 Constitution guarantees the right to personal liberty, and the High Court exercises inherent jurisdiction to hear habeas corpus applications challenging the legality of any detention.

Administrative Tribunals

Nigeria maintains numerous administrative tribunals exercising quasi-judicial functions, including the Tax Appeal Tribunal, the Code of Conduct Tribunal, the Industrial Court (now the National Industrial Court), and specialized regulatory tribunals established by statute. The Constitution (Third Alteration) Act 2010 elevated the National Industrial Court to constitutional status with exclusive jurisdiction over labour matters.

The Stare decisis principle applies to tribunal decisions, and tribunals must observe the rules of natural justice. In Adeyemi v Opeyemi (2005) 12 NWLR (Pt 940) 560, the Court of Appeal emphasized that administrative tribunals must comply with the audi alteram partem rule, ensuring that parties are given a fair hearing.

Judicial Review Procedure

Order 40 of the Federal High Court (Civil Procedure) Rules 2019 governs applications for judicial review. The procedure requires applicants to seek leave of court within three months of the decision or act complained of. The court considers whether the applicant has sufficient interest (locus standi) and whether there is an arguable case. In Fawehinmi v President, FRN (2007) 14 NWLR (Pt 1054) 275, the Supreme Court liberalized the locus standi requirement for public interest litigants seeking to challenge governmental action affecting the public at large.

Grounds for Judicial Review

Nigerian law recognizes three classical grounds for judicial review: illegality, irrationality (Wednesbury unreasonableness), and procedural impropriety. Illegality arises where a public body acts without legal authority or exceeds its statutory powers. Irrationality applies where the decision is so unreasonable that no reasonable authority could have reached it, following the test in Associated Provincial Picture Houses Ltd v Wednesbury Corporation (1948) 1 KB 223. Procedural impropriety encompasses breach of natural justice and failure to follow prescribed statutory procedures.

Ouster Clauses and Justiciability

Ouster clauses purport to exclude or limit judicial review of administrative action. Nigerian courts have consistently held that ouster clauses cannot wholly exclude the supervisory jurisdiction of the High Court. In Lakanmi v A-G (West) (1970) 1 All NLR 57, the Supreme Court declared that even constitutional provisions purporting to oust the court’s jurisdiction cannot prevent the court from inquiring into the validity of legislation affecting fundamental rights.

Conclusion

Administrative law in Nigeria continues to develop as courts assert their constitutional role in checking executive and administrative power. The constitutional supremacy established by section 1 of the 1999 Constitution, combined with the robust supervisory jurisdiction of the High Courts, provides a framework for accountable governance. Recent trends include expanded locus standi, growing recognition of legitimate expectations, and increased judicial willingness to review administrative discretion.
