Overview
The Federal Republic of Nigeria has no bilateral extradition treaty with the Federal Republic of Germany. Nigeria is neither a party to the European Convention on Extradition (ECE) nor an EU member; the European Arrest Warrant does not apply. Extradition is therefore assessed exclusively on a treaty-less basis under Sections 1 ff. IRG and presupposes a formal assurance of reciprocity by Nigeria (Section 5 IRG). On the Nigerian side the procedure follows the Extradition Act (Cap. E25, Laws of the Federation of Nigeria 2004).
In practice Nigeria is of considerable relevance. Both states are Interpol members, so that arrests on the basis of Nigerian Red Notices and diffusions occur; in addition there are formal requests that have been granted on both sides in the past. The focus lies on allegations of economic crime, fraud and cybercrime — in particular advance-fee fraud and internet fraud (so-called "419" offenses, after the section of the Nigerian Criminal Code of the same number), money laundering and investment fraud. Owing to the large Nigerian diaspora in Germany and Europe, requests frequently concern persons resident here.
The defense in Nigeria constellations is shaped by two structural particularities that regularly call an extradition into question: the desolate detention conditions, in many cases contrary to human rights, with extremely long pre-trial detention (Section 73 sentence 1 IRG in conjunction with Article 3 ECHR), as well as the continuing death penalty, which in the twelve Sharia states of the north also includes cruel forms of punishment (Section 8 IRG). Added to this are rule-of-law deficiencies, judicial corruption and a precarious security situation.
Legal basis
In the absence of an international agreement, the Act on International Mutual Legal Assistance in Criminal Matters (IRG) of 23 Dec 1982 applies directly on the German side. Treaty-less extradition presupposes, under Section 5 IRG, an assurance of reciprocity; under Section 3 IRG dual criminality is required (the offense must carry a maximum penalty of more than one year's imprisonment, and in enforcement cases at least four months of the sentence must remain to be served). Political, military and exclusively fiscal offenses are subject to Sections 6 and 7 IRG.
For German citizens, extradition to Nigeria is excluded under Article 16(2) of the Basic Law in conjunction with Section 80 IRG; the relaxation in Section 80 IRG applies only to extraditions to EU member states. This bar also applies to German-Nigerian dual nationals (cf. BVerfGE 113, 273 — European Arrest Warrant I). Multiple nationality has been permissible without a retention permit since the Act to Modernize Citizenship Law of 27 June 2024, which increases the number of German-Nigerian dual nationals.
On the Nigerian side the Extradition Act (Cap. E25 LFN 2004) is decisive; the extradition decision rests with the Attorney-General of the Federation and the Federal Ministry of Justice, while the court proceedings are conducted before the Federal High Court. In substantive terms, Nigerian criminal law rests on a split system: in the south the Criminal Code applies, in the north the Penal Code, overlaid in twelve northern states by Islamic Sharia criminal law (Sharia Penal Codes). On the German side, the Higher Regional Courts decide on admissibility (Sections 13 ff. IRG); the granting decision is made by the General Public Prosecutor's Offices, and in cases of fundamental or foreign-policy significance by the Federal Office of Justice in agreement with the Federal Foreign Office.
Country-specific issues in Nigeria
Detention conditions and excessively long pre-trial detention — the decisive bar: The Nigerian penal system (administered by the Nigerian Correctional Service) is marked by massive overcrowding, desolate hygiene, malnutrition and inadequate medical care. According to reports, the Lagos prison Kirikiri holds over 2,500 detainees against a capacity of around 800; nationwide, out of some 84,000 detainees, two-thirds are permanently held in pre-trial detention, in many cases for years without a judgment. This situation is the regularly decisive argument in the extradition proceedings under Section 73 sentence 1 IRG in conjunction with Article 3 ECHR (see the dedicated section below).
The death penalty and Sharia criminal law in the north: Nigeria has not abolished the death penalty. While a de facto moratorium on executions exists — the last documented executions date from December 2016 — according to human-rights organizations more than 3,000 persons are held on death row; execution depends solely on the signature of the respective state governors and is reversible at any time. In the twelve northern Sharia states, cruel forms of punishment threaten for hudud offenses, including stoning (for example for adultery), flogging and amputation. Where there is a relevant charge, extradition is admissible under Section 8 IRG only subject to an effective, verifiable assurance.
Blasphemy and religious-political persecution: In several northern states blasphemy carries the death penalty under Sharia law. The case of the singer Yahaya Sharif-Aminu, who in 2020 was sentenced in Kano to death by hanging over a WhatsApp message classified as blasphemous, is pending before the Supreme Court of Nigeria; the UN Working Group on Arbitrary Detention declared his detention contrary to international law in August 2024. Proceedings with a religious, political or ethnic persecution background act as a bar under Section 6(1) IRG (political offense) and Section 6(2) IRG (threatened persecution on grounds of religion, political conviction or membership of a social group).
The rule of law, judicial corruption and the security situation: The Nigerian judiciary is burdened by documented corruption, political influence and serious procedural delays; a fair conduct of proceedings is not consistently guaranteed. Added to this is a precarious security situation due to Islamist terrorism (Boko Haram, ISWAP) in the northeast as well as widespread banditry and kidnapping, which also impair the conditions in custody and effective legal protection.
Economic and cybercrime as a typical ground for requests: The practical focus lies on allegations of advance-fee and internet fraud ("419"), investment fraud, money laundering and organized cybercrime. With these offenses, dual criminality (Section 3 IRG) can as a rule be affirmed, so that the focus of the defense lies on the detention and procedural guarantees (Section 73 IRG); at the same time, the mirror-image review must be carried out carefully in the case of broadly framed Nigerian offenses.
Detention conditions and the human-rights review
Detention conditions in the Nigerian penal system are documented by numerous independent sources (the US State Department Human Rights Report, Amnesty International, Human Rights Watch, UNODC and the human-rights reporting of the Federal Foreign Office) as seriously contrary to human rights. To the fore are the Lagos prison Kirikiri (Maximum and Medium Security) and numerous overcrowded facilities nationwide. Reports describe three- to fourfold overcrowding, sleeping on the floor, lack of running water, blocked or absent sanitary facilities, malnutrition, the outbreak of diseases such as cholera and tuberculosis, deaths in custody and ill-treatment. Particularly grave is the excessively long pre-trial detention: around two-thirds of all detainees wait without a judgment, frequently for years, for a hearing date.
It follows from German case law that, in the case of an extradition to Nigeria, the standard of review developed for Article 3 ECHR / Article 4 of the EU Charter (Aranyosi/Căldăraru, ECJ C-404/15 and C-659/15 PPU — to be applied as a standard also outside the European Arrest Warrant) regularly stands in the way of admissibility. A mere diplomatic assurance ("humane accommodation") is not sufficient in the absence of a reliable monitoring mechanism; what is required is a concrete, facility-specific and monitorable assurance naming the facility and subject to monitoring by the German Embassy in Abuja. In view of the situation documented across the board, such an assurance is in practice difficult to obtain and must be reviewed critically in the individual case as to its reliability.
Consular assistance is provided through the German Embassy in Abuja on the basis of the Vienna Convention on Consular Relations of 24 Apr 1963 (VCCR). In the case of German-Nigerian dual nationals, consular access following a surrender is not guaranteed in every case, since Nigeria treats its own nationals primarily as such — a point that further weakens the monitorability of an assurance and must be introduced into the admissibility proceedings.
Lines of defense
The defense in Nigeria extradition proceedings regularly holds good prospects of success where it is structured by a lawyer at an early stage. Review framework:
- Section 73 sentence 1 IRG in conjunction with Article 3 ECHR (detention conditions): Regularly the decisive argument. Systematically introduce reports from the US State Department, Amnesty International, Human Rights Watch and UNODC on Kirikiri and the Nigerian penal system into the admissibility proceedings; work out excessively long pre-trial detention and overcrowding as independent grounds for refusal. A concrete, facility-specific and monitorable assurance with monitoring by the Embassy in Abuja as the minimum requirement — where it is not monitorable, the bar continues to apply.
- Section 8 IRG (death penalty): Where the charges carry the threat of the Nigerian death penalty (murder, aggravated robbery, hudud and blasphemy offenses), extradition only subject to an effective, monitorable assurance. The de facto moratorium on executions since 2016 does not rule out Section 8 IRG, since the legal existence and the political reversibility (the governors' signature) are decisive.
- Section 6(2) IRG (threatened political/religious persecution): Where there is a connection to religion (in particular blasphemy allegations), political activity, or ethnic or social group membership, it must be reviewed without fail — regularly a bar. It also covers an ostensibly "criminal" request behind which lies a purpose of persecution.
- Section 6(1) IRG (political offense): Applicable in the case of security- and religion-related offenses as well as proceedings with a political slant.
- Article 16(2) of the Basic Law in conjunction with Section 80 IRG: Where there is German citizenship — including German-Nigerian dual nationals — extradition is excluded.
- Section 3 IRG (dual criminality): In the case of Nigeria-specific or broadly framed offenses (Sharia offenses, far-reaching cybercrime offenses), careful subsumption and mirror-image review; in the case of blasphemy and morality offenses, a German counterpart is lacking.
- Section 5 IRG (reciprocity): Treaty-less — a formal, reliable assurance of reciprocity is required.
- Section 11 IRG (rule of specialty): In treaty-less extradition, to be secured separately through the granting decision; a concrete enumeration of the granted offenses, with supplementary requests only subject to renewed consent.
- Section 9 IRG (double jeopardy / ne bis in idem): Where there are parallel investigations in Germany or third states, review the bar effect.
- Interpol/CCF: Challenge a politically or abusively motivated Red Notice or diffusion under Article 3 of the Interpol Constitution; an early CCF deletion request (Commission for the Control of INTERPOL's Files), a protective brief with the BKA and the Federal Office of Justice.
- Constitutional complaint with an urgent application (Section 32 BVerfGG): Following the declaration of admissibility by the OLG, the standard remedy in the case of fundamental-rights violations (Article 1(1), Article 2(2), Article 25 of the Basic Law in conjunction with Article 3 ECHR); where the detention-conditions and persecution objections have been carefully prepared, the prospects are not slight.
Legal representation in Nigerian extradition proceedings
An extradition case is a specialized mutual-legal-assistance procedure that goes beyond classic criminal defense. Engaging a defense lawyer specialized in extradition law at an early stage is regularly decisive — not only after the formal extradition arrest warrant has been issued, but already from the moment of an arrest based on an Interpol notice, an SIS alert or a European Arrest Warrant.
As a Certified Specialist in Criminal Law with a focus on extradition law, I advise and represent affected persons nationwide before the competent Higher Regional Courts and in constitutional complaint proceedings before the Federal Constitutional Court.
