The Supreme Court is the ultimate authority on the meaning and interpretation of the Constitution of the Federal Republic of United State. When constitutional questions arise in any court, those questions may ultimately reach the Supreme Court for final and binding resolution.

What is Constitutional Interpretation?

Constitutional interpretation is the process by which the Supreme Court determines the meaning, scope, and application of provisions of the Constitution in specific cases or controversies. The Court’s interpretation is final and binding on all courts, governments, and institutions in Nigeria.

Types of Constitutional Questions

• Interpretation of fundamental rights provisions (Chapter IV of the Constitution)
• Questions of legislative competence — whether the National Assembly or a State House of Assembly has power to enact a particular law
• Separation of powers disputes between the executive, legislative, and judicial branches
• Federal-state relations — conflicts between federal and state laws
• Questions regarding the eligibility or qualification of public officers
• Disputes over the validity of elections, constitutional amendments, and executive actions

How Constitutional Questions Reach the Supreme Court

Constitutional questions typically reach the Supreme Court through the normal appellate process — a party raises a constitutional issue in a lower court, and the matter works its way up through the Court of Appeal to the Supreme Court. The Constitution also grants the Supreme Court original jurisdiction over specific constitutional matters, meaning some cases begin directly in the Supreme Court without going through lower courts.
