Introduction
Extradition sits at the intersection of criminal procedure and international cooperation. It is the legal mechanism through which one state surrenders a person to another state to face prosecution or serve a sentence for crimes within the requesting state’s jurisdiction.
What “Extradition” Means
The Court of Appeal has adopted the plain meaning: “the official surrender of an alleged criminal by one state or nation to another having jurisdiction over the crime charged.”OKOYOMON v. A.G. Federation (2016) LPELR-57485(CA).
Nature of Extradition Proceedings
The Supreme Court has clarified the unique legal character of extradition proceedings in Nigeria. In A.G. FEDERATION V. ANUEBUNWA (2022) LPELR-57750(SC),the Court described extradition proceedings as sui generis and explained their relationship with criminal law.
The Court stated:
“Generally, all cases and matters before the Courts in Nigeria are either civil or criminal. The proper classification of a case is important because of the applicable procedural rules and standards. Extradition Proceedings in Nigeria are sui generis and strictly guided by the Extradition Act and Extradition Proceedings Rules. The proceedings are criminal to the extent that they deal with a criminal charge or conviction raised by the requesting State. However, unlike regular criminal proceedings, extradition proceedings do not result in a determination of whether the alleged fugitive is guilty or innocent, nor do they end in a post-conviction sentence. Extradition proceedings are therefore a peculiar kind of criminal proceedings.”
Per HELEN MORONKEJI OGUNWUMIJU, JSC (Pp. 56–57 Paras. E–B).
Core Legal Framework
Nigeria’s extradiction regime is primarily governed by the Extradition Act, Cap E25, LFN 2004 (as amended),together with applicable treaties and cooperation schemes (e.g., the London Scheme for Extradition within the Commonwealth). The Courts have emphasized that Nigerian statutes should be interpreted in a way that avoids breaching international obligations where those obligations are reflected in our laws. OKOYOMON v. A.G. Federation (2016) LPELR-57485(CA).
Treaty or No Treaty?
With a treaty/common scheme:Nigeria has obligations (reflected domestically) to cooperate with requests that meet statutory requirements.
Without a treaty:“there is no duty under international law to extradite.” OKOYOMON v. A.G. Federation (Per Aboki, JCA).
Essence of Extradition Proceedings
The Court of Appeal also clarified the core objective of extradition hearings in ANUEBUNWA v. A.G.F (2020) LPELR-51434(CA).
The Court emphasized that the proceeding is primarily concerned with whether the requesting State has placed sufficient material before the court to justify surrender of the alleged fugitive.
The Court held:
“The whole essence of an extradition proceeding like the trial judge has said in page 326 of the Record of Appeal is for the Applicant to establish by credible evidence, that is by producing to the judge in the case of a fugitive criminal accused of an offence claimed to be an extradition offence, a warrant issued outside Nigeria authorizing the arrest of the fugitive.”
Per MOHAMMED BABA IDRIS, JCA (P. 16 Paras. D – E).
The Court’s Limited but Crucial Role
Per the Supreme Court in A.G.F v. Anuebunwa (2022):
The judge is not trying the offence on the merits. The judge asks whether the evidence would justify committal if the offence had been committed in Nigeria (Section 9). If yes, the court commits the person to custody to await the Attorney-General’s surrender order.
Standard of Proof
The prima facie threshold applies to the extradition hearing. By contrast, any fundamental rights suit filed by the person sought (e.g., challenging detention/conditions) is civil, where proof is on a balance of probabilities. A.G.F v. Anuebunwa (2022) LPELR-57750(SC).
Identity: “He Who Asserts Must Prove”
Where identity is disputed, the burden lies on the applicant/requesting state to show the person before the court is the person sought. In ANUEBUNWA v. A.G.F (2020), the Court of Appeal faulted the grant of extradition where the government failed to discharge this burden after a concrete challenge to identity.
Substantive and Human-Rights Safeguards
Extradition is bounded by statutory and constitutional protections:
Passage of Time: If, given the time elapsed since the offence, surrender would be unjust or oppressive, extradition is barred. IGWILO v. A-G Federation (2024) LPELR-61816(CA)(applying Section 3(c) Extradition Act and the 1931 Treaty).
Rule of Law & Due Process: Extradition must follow lawful procedures. This requirement is also linked to the concept of rendition, which the Supreme Court examined in FRN v. KANU (2023) LPELR-79929(SC).
The Court explained the meaning of rendition and distinguished lawful transfer of fugitives from what is commonly called extraordinary rendition.
“Interestingly, one word that has gained immeasurable traction in the proceedings of the two Courts below, and indeed this Court, is RENDITON…….. In the present context, the term render denotes: The return of a fugitive from one state to the state where the fugitive is accused or was convicted of a crime.……..………..… The transporting of a prisoner or fugitive from one jurisdiction to another that has rightfully requested custody. With passage of time, the term extraordinary rendition equally gained traction…….… thereby denoting: The transfer, without formal charges, trial, or Court approval, of a person suspected of being a terrorist…..… to a foreign country for imprisonment and interrogation………. See BLACK’S LAW DICTIONARY, 11th edition 2019 @ 1550.……”
Per IBRAHIM MOHAMMED MUSA SAULAWA, JSC (Pp. 106–108 Paras. F–E).
In essence, the Court highlighted the distinction between lawful extradition carried out under statutory and treaty procedures and extraordinary rendition, which involves the transfer of a person without formal legal process. The discussion reinforces the centrality of due process and adherence to the rule of law in cross-border criminal cooperation.
Doctrine of Specialty (Section 15)
A surrendered person should be tried only for the offence(s) for which they were surrendered (and closely related offences), absent consent from the surrendering state. KANU v. FRNexplores when specialty applies and when it may not (e.g., where there was no lawful surrender by the foreign state).
Effect of Extraordinary Rendition on Jurisdiction
A related issue in extradition and international criminal cooperation is whether the unlawful abduction or extraordinary rendition of a suspect from another country can invalidate criminal proceedings before Nigerian courts.
The Supreme Court addressed this issue in FRN v. KANU (2023) LPELR-79929(SC).
The Court held:
“……This far-reaching decision of the lower Court triggered serious discourse, particularly on whether an extraordinary rendition of a person will have the consequence of rendering the entire charge against him null and void. Courts are creations of statutes, and they are created along with their jurisdiction and powers as conferred on them by the enabling statute, such statutory jurisdiction can only be taken away by another statutory enactment, in other words statutory jurisdiction cannot be taken away by mere omission to follow due process in securing the attendance in Court by an accused person to answer the charge against him… The provisions of Section 251 of the Constitution of the Federal Republic of Nigeria (as amended), and Section 32 of the Terrorism Prevention Act, 2011 as amended by the Terrorism Prevention (Amendment) Act 2013 are still valid and subsisting… the provisions cannot be rendered void by mere reason of irregular and extraordinary rendition of the escapee Respondent… The decision of the lower Court throwing away the entire charge is obviously wrong… The Respondent must therefore march to the trial Court and answer the charge against him.……”
Per TIJJANI ABUBAKAR, JSC (Pp. 124–128 Paras. B–B).
In essence, the Supreme Court clarified that while the government is expected to comply with lawful extradition procedures, an irregular or unlawful rendition of an accused person does not automatically nullify the criminal charge or deprive the trial court of jurisdiction. Jurisdiction flows from the Constitution and relevant statutes, and it cannot be defeated solely by the manner in which the accused was brought before the court.
Duties of the Attorney-General
The Supreme Court in A.G.F v. Anuebunwa (2022) detailed key averments the Attorney-General of the Federation must make, including:
1. Assurance the request isn’t for political/discriminatory reasons.
2. Confirmation of dual criminality/extraditability and non-triviality.
3. Comfort that surrender won’t be unjust or oppressive, and that fair-trial guarantees exist in the requesting state.
4. Confirmation that no Nigerian proceedings are pending for the same offence(s).
Commonwealth Cooperation and Domestic Effect
The Court of Appeal in OKOYOMON aligned the London Scheme with the Extradition Act, emphasizing that the Act substantially incorporates its relevant clauses—reinforcing that our courts give effect to cooperative obligations where domesticated.
Key Grounds for Resisting Extradition
A person sought for extradition may challenge the request on several grounds, including:
mistaken identity
political offence exception
passage of time rendering surrender oppressive
risk of unfair trial in the requesting state
violation of constitutional rights
Prepare for potential fundamental rights applications (detention conditions, fair-trial risk). In some situations, issues of detention and bail may also arise before or during extradition proceedings. See our earlier guide on applying for bail in Nigeria.
Practitioner’s Checklist (At a Glance)
1. Treaty/Legal Basis: Identify the treaty or cooperative scheme and show how the Extradition Act accomodates it.
2. Attorney-General’s Discretion: Ensure the supporting affidavit satisfies Sections 3, 9, 11 of the Extradition Act.
3. Extradition Documents (Section 17): File authenticated warrants, charge/depositions, and conviction certificates (if any).
4. Prima Facie Case: Map facts to Nigerian offences to show committal-level sufficiency.
5. Identity Proof: Anticipate and front-load cogent identity evidence (photos, biometrics, sworn identifiers, consistent particulars).
6. Bars to Surrender: Assess Section 3 (time bar, political character, oppression, etc.) and Section 15 (specialty).
7. Rights Landscape: Prepare for potential fundamental rights applications (detention conditions, fair-trial risk).
8. Scope of Hearing: Keep submissions focused—extradition is not the trial.
Conclusion
Nigerian extradition law balances international cooperation with individual protections. Courts look for prima facie sufficiency, proper authentication, clear identity, and fair-trial assurances, all while respecting specialty and time-bar safeguards. Counsel should be meticulous with the record and anticipate identity and rights-based challenges from the first filing.
