Introduction and Facts

Introduction

Fawehinmi v. Abacha is one of the most important constitutional and human rights decisions in Nigerian legal history. The case arose during the military regime of General Sani Abacha, a period characterized by extensive use of military decrees and restrictions on civil liberties. The decision addressed the relationship between domestic law and international human rights treaties, particularly the African Charter on Human and Peoples’ Rights.

The significance of the case lies in the Supreme Court’s recognition that the African Charter, having been domesticated by the National Assembly, forms part of Nigerian law and is enforceable by Nigerian courts. The judgment remains a leading authority on the status of international human rights instruments in Nigeria and the protection of fundamental rights.[1]

Facts of the Case

The respondent, a legal practitioner, was arrested without warrant at his residence on Tuesday, January 30 1996, at about 6 a.m., by six men who identified themselves as operatives of the State Security Service (referred to as SSS) and policemen, and taken away to the office of the SSS at Shangisha Lagos, where he was detained. At the time of the arrest, the respondent was not informed of, nor charged with, any offence. He was later detained at Bauchi prisons.

Consequently, the he applied ex-parte through his Counsel, to the Federal High Court, Lagos, pursuant to the Fundamental Rights (Enforcement Procedure) Rules 1979 for the reliefs against the 4 respondents who are now appellants before us and shall hereinafter be referred to as appellants.

A declaration that the arrest of the applicant, Chief Gani Fawehinmi at his residence at 9A Ademola Close GRA, Ikeja Lagos on Tuesday, January 30, 1996, by the State Security Service(S.S.S.) or officers, servants, agents, privies of the respondents and /or of the Federal Military Government constitutes a gross violation of the applicant’s fundamental rights guaranteed under Sections 31, 32 and 38 of the 1979 Constitution and Articles 4, 5, 6 and 12 of the African Charter on Human & Peoples’ Rights (Ratification and Enforcement) Act Cap 10. Laws of Federation of Nigeria 1990 and is therefore illegal and unconstitutional. 

Alternatively, Chief Fawehinmi sought an order of mandamus compelling the authorities to arraign him before a competent court or tribunal in accordance with the Constitution and the African Charter. He also requested an injunction restraining further violations of his fundamental rights and claimed ₦10 million damages for his alleged unlawful arrest and detention.

Legal Issues

1. Whether the African Charter on Human and Peoples’ Rights, having been domesticated by the National Assembly, was part of Nigerian law and directly enforceable in domestic courts.
2. Whether the African Charter enjoyed supremacy over conflicting domestic laws and military decrees.
3. Whether Nigerian courts retained jurisdiction to intervene in detentions authorized under Decree No 2 despite ouster clauses.
4. Whether the detention of Chief Gani Fawehinmi was unlawful and whether he was entitled to the reliefs sought.[2]

Arguments Presented by the Parties

Contentions by the Appellants

The appellants argued that the Constitution (Suspension and Modification) Decree No. 107 of 1993 and other military decrees had ousted the jurisdiction of the courts to review actions taken by the military government. They contended that under military rule, decrees constituted the supreme law of the land and therefore prevailed over all other laws, including the African Charter on Human and Peoples’ Rights. Accordingly, they maintained that the respondent could not rely on the Charter to challenge his arrest and detention.

Contentions by the Respondent

The respondent argued that the African Charter on Human and Peoples’ Rights had been domesticated through the African Charter (Ratification and Enforcement) Act and therefore formed part of Nigerian law. He contended that his arrest and detention violated his rights to personal liberty and fair hearing guaranteed under the Charter. Consequently, he maintained that the courts retained the jurisdiction to enforce those rights and grant appropriate relief.

Court’s Reasoning and Analysis

The Supreme Court examined the status of the African Charter on Human and Peoples’ Rights within the Nigerian legal system. The Court held that under section 12 of the Constitution, treaties do not automatically become part of Nigerian law upon ratification. However, once a treaty is domesticated by an Act of the National Assembly, it becomes enforceable as part of Nigerian municipal law[3]. Since the African Charter had been incorporated through the African Charter (Ratification and Enforcement) Act, its provisions could be invoked before Nigerian courts. The Court emphasized that the Charter occupied a special position because it embodied international human rights obligations voluntarily assumed by Nigeria. Nevertheless, the Court rejected the argument that the Charter was superior to military decrees. During military rule, decrees constituted the supreme law of the land and could override any inconsistent statutory provision, including the African Charter. The Court further considered the effect of the ouster clauses contained in Decree No. 2 of 1984 and Decree No. 107 of 1993. While acknowledging the broad language of those decrees, the Court held that the judiciary retained a limited power to determine whether executive action was genuinely authorized by the relevant decree. The Court therefore affirmed the role of judicial review in ensuring that government authorities acted within the powers conferred by law. In reaching its decision, the Court relied on previous authorities, including Ogugu v. State, and emphasized the importance of protecting fundamental rights through both constitutional and statutory mechanisms. The judgment clarified the relationship between international human rights law and domestic law in Nigeria and established that domesticated treaties are enforceable in Nigerian courts.

Judgment

The Supreme Court dismissed the appeal but issued landmark pronouncements on the enforceability of the African Charter.

Key rulings included:

1. The African Charter, having been domesticated, forms part of Nigerian law and is enforceable in Nigerian courts.
2. The Charter guarantees rights that individuals may directly invoke before Nigerian courts without additional legislative enactment.
3. However, during military rule, decrees were supreme in the legal hierarchy. In case of inconsistency between a decree and the African Charter, the decree prevailed.
4. Despite this general principle, the Court in this case ruled that the detention of Fawehinmi was unlawful, as it unjustifiably violated rights guaranteed under the African Charter.

Expanded Key Rulings and Remedies

The Court clarified important principles on remedies for rights violations:

Application of the African Charter: The provisions of the African Charter on Human and Peoples’ Rights were directly applicable in Nigerian courts. Individuals could rely on them without need for fresh legislation.

Supremacy of the Charter: The Court held that the African Charter, as a domesticated statute, took precedence over inconsistent domestic laws and decrees. In particular, ouster clauses in military decrees could not extinguish Charter-guaranteed rights.

Unlawfulness of Detention: The Court found that Fawehinmi’s detention during the 1998 protest violated his rights to liberty, fair hearing, and dignity.

Ratio Decidendi

The ratio decidendi of General Sani Abacha & Ors v. Chief Gani Fawehinmi (2000) is that an international treaty does not have the force of law in Nigeria merely because it has been ratified; it becomes enforceable only after it has been domesticated by an Act of the National Assembly pursuant to section 12 of the Constitution. Once domesticated, the treaty forms part of Nigerian law and may be enforced by Nigerian courts. However, during military rule, a valid military decree prevails over any inconsistent statutory provision, including a domesticated treaty.

Significance of the Decision

The decision remains one of the most influential authorities on the status of international human rights treaties in Nigeria. It clarified that domesticated treaties form part of Nigerian law and can be enforced by domestic courts.

Implications and Impact

The judgment strengthened human rights litigation in Nigeria by allowing litigants to rely on the African Charter before domestic courts. It has been cited extensively in subsequent constitutional and human rights cases.

Critical Evaluation

One strength of the decision is its recognition of the enforceability of international human rights norms within the domestic legal system. However, the Court’s acceptance of the supremacy of military decrees limited the practical protection of rights during military rule. Critics argue that this aspect of the judgment reflected the constraints of the political environment rather than a robust commitment to judicial protection of rights.[4]

Conclusion

The decision in this case remains a landmark authority in Nigerian constitutional and human rights jurisprudence. The Supreme Court clarified the legal status of international treaties within the Nigerian legal system, holding that treaties become enforceable only after domestication by the National Assembly. By recognizing the African Charter on Human and Peoples’ Rights as part of Nigerian law, the Court strengthened the protection of human rights and expanded the scope of rights enforcement in Nigerian courts. At the same time, the Court acknowledged the supremacy of military decrees during military rule, thereby reflecting the constitutional realities of that era. The case continues to serve as a leading precedent on the relationship between international law and domestic law in Nigeria and underscores the judiciary’s vital role in safeguarding fundamental rights and the rule of law.
