Rule of Law under the 1999 Constitution

Introduction

The rule of law is a foundational principle of the Nigerian constitutional order, underlying the structure and operation of the legal system. While not expressly defined in the Constitution, the rule of law is implicit in numerous constitutional provisions and has been elaborated by the Supreme Court as a fundamental feature of the Nigerian state. The concept encompasses the supremacy of the Constitution, the accountability of government under law, the independence of the judiciary, and the protection of fundamental rights.

Constitutional Foundations

Section 1 of the 1999 Constitution declares the Constitution to be supreme, providing that any law inconsistent with it is void to the extent of the inconsistency. This provision gives practical effect to the rule of law by establishing a hierarchy of legal norms with the Constitution at the apex. The supremacy clause ensures that all governmental action, whether legislative, executive, or judicial, must conform to constitutional requirements.

Separation of Powers

The Constitution establishes a tripartite separation of powers among the legislative, executive, and judicial branches. This separation is a structural safeguard for the rule of law, preventing the concentration of power in any single branch. The Supreme Court in Lakanmi v A-G (West) (1970) emphasized that the rule of law requires that no person or institution be above the law, including the government itself.

Judicial Independence

The independence of the judiciary is essential to the rule of law. The Constitution guarantees judicial independence through provisions on judicial appointment (by the NJC), security of tenure (section 292), financial autonomy, and immunity from suit for judicial acts. The National Judicial Council (NJC) serves as a buffer against executive interference in judicial appointments and discipline.

Access to Justice

The rule of law requires that citizens have access to courts to enforce their rights and challenge governmental action. The Constitution guarantees the right of access to court (section 46) and provides for legal aid and the enforcement of fundamental rights. The Supreme Court has liberalized the rules of locus standi to facilitate public interest litigation challenging governmental action.

Equality Before the Law

Section 17 of the Constitution provides that all citizens have equality of rights, obligations, and opportunities. The principle of equality before the law is a core element of the rule of law, requiring that laws apply equally to all persons and that no person or group is above the law. The courts have applied this principle to strike down discriminatory laws and practices.

Legal Certainty and Non-Retroactivity

The rule of law requires that laws be clear, accessible, and predictable. Section 36(8) of the Constitution prohibits the retroactive application of criminal laws (ex post facto laws), providing that no person shall be held guilty of a criminal offense for an act that was not an offense at the time it was committed. This principle ensures legal certainty and protects against arbitrary state action.

Judicial Review

The rule of law is enforced through judicial review of legislative and executive action. The courts have the power to declare unconstitutional legislation void and to set aside unlawful administrative action. The Supreme Court has consistently affirmed that the rule of law requires that governmental action be authorized by law and that the courts have jurisdiction to determine the legality of governmental action.

Conclusion

The rule of law is a foundational principle of the Nigerian Constitution, implicit in its structure and express provisions. The supremacy of the Constitution, the independence of the judiciary, equality before the law, legal certainty, and the availability of judicial review are essential elements of the rule of law in Nigeria. The courts continue to play a vital role in upholding the rule of law against challenges from executive and legislative overreach.
