Just recently, the world watched closely as President Bola Ahmed Tinubu completed a state visit to the United Kingdom, marking one of the most consequential diplomatic engagements of his tenure so far. Among the discussions and agreements that emerged, a new Migration Partnership Agreement between Nigeria and the United Kingdom drew particular attention due to its implications for thousands of Nigerians living in the UK, many of whom face uncertain immigration status.
The pact, announced on March 15, 2026, promised to accelerate the return of Nigerian nationals who are in the UK without legal authorization, including failed asylum seekers and certain foreign offenders. Yet, almost immediately after the announcement, one of Nigeria’s most prominent legal minds, Femi Falana, SAN, raised fundamental questions about the legality, constitutionality, and human rights implications of the agreement.
His concerns have reverberated across political, legal, and social media spaces, sparking debates about how international treaties should be executed within Nigeria’s constitutional framework and what safeguards must exist to protect citizens from potential abuse.
What the UK–Nigeria Migration Agreement Entails
The Migration Partnership Agreement, as outlined in March 2026, seeks to create a formal mechanism for the return of Nigerian nationals in the United Kingdom who are without lawful status. This includes failed asylum seekers whose claims have been denied, as well as certain foreign offenders who have completed their sentences in the UK. One of the most notable aspects of the agreement is the proposed use of documents colloquially referred to as “UK letters” to substitute for Nigerian passports in order to facilitate returns.
These letters would serve as verification of nationality and authorization for deportation, expediting what is described as a cumbersome process in conventional practice. The deal also includes provisions for the potential transfer of prisoners who have been convicted in the UK to serve sentences in Nigerian correctional facilities.
While framed as a pragmatic solution to streamline migration processes, the arrangement immediately drew scrutiny from legal and human rights experts who questioned whether bypassing traditional verification mechanisms and parliamentary domestication of treaties could pose serious constitutional issues.
Femi Falana’s Legal Objections and Constitutional Position
Femi Falana, SAN, who has built a reputation over decades as a defender of constitutional rights and human dignity, has publicly challenged the enforceability of the Migration Partnership Agreement. His first major concern centers on the lack of constitutional backing for the pact within Nigeria. Under Section 12(1) of the 1999 Nigerian Constitution, treaties and international agreements only gain the force of law domestically after being enacted by the National Assembly.
Since the UK–Nigeria Migration Partnership Agreement has not yet undergone legislative domestication, Falana argues that it cannot legally be enforced against Nigerian citizens, and any actions taken under it may constitute an unconstitutional exercise of executive authority. He emphasizes that bypassing this legislative step undermines both the supremacy of the Constitution and the democratic principle of separation of powers, effectively allowing the executive branch to create binding obligations for citizens without proper parliamentary oversight.
Falana’s second point of contention is the potential violation of due process rights. The proposed use of “UK letters” instead of passports or other formal verification documents could allow deportations to occur without proper confirmation of citizenship. In practical terms, this means individuals may be returned to Nigeria based on documentation that lacks rigorous validation, raising the possibility of wrongful removal.
Falana notes that this mechanism risks circumventing existing judicial and administrative procedures that ensure individuals have the opportunity to challenge their nationality status or deportation orders in court. For him, this is not a mere technicality; it represents a serious threat to constitutional protections and the fundamental right to a fair hearing enshrined in Section 36 of the Nigerian Constitution.
Risk of Arbitrary Deportation and Human Rights Concerns
A central pillar of Falana’s critique is the risk that the agreement could create conditions for arbitrary deportation. By lowering the threshold for what constitutes acceptable documentation and bypassing established judicial processes, the pact may enable authorities to remove individuals without giving them sufficient notice, opportunity for legal representation, or the ability to challenge their removal. Falana warns that such actions could violate not only Nigeria’s constitutional guarantees but also international human rights obligations.
Nigeria is a signatory to the African Charter on Human and Peoples’ Rights as well as the International Covenant on Civil and Political Rights, both of which require that deportation procedures respect human dignity, provide access to remedies, and avoid wrongful or punitive removals.
These obligations are binding on the Nigerian government and create a legal expectation that any international agreement, particularly one that directly affects citizens, must be executed with full attention to procedural safeguards and the protection of fundamental rights.
Right to Family Life and Social Considerations
Falana further highlights the human dimension of the agreement, noting that many Nigerians in the UK are long-term residents with spouses, children, and established communities. Deportations carried out without careful consideration of familial and social circumstances could irreparably disrupt lives. He cites precedent from UK immigration law emphasizing the best interests of children and the principle of proportionality in removal decisions.
Failure to account for these factors may not only violate international human rights standards but also undermine the moral legitimacy of the agreement. In practical terms, families could be separated, children uprooted from schools, and communities fractured if the agreement is implemented without safeguards that account for these human realities.
Falana’s critique, therefore, is rooted in both legal reasoning and concern for the tangible impact on people’s lives, highlighting the intersection of law, ethics, and policy.
Prisoner Transfers and Legal Consistency
Another element of the agreement that Falana questions is the provision allowing for convicted persons in the UK to serve their prison sentences in Nigeria. According to Nigerian law, imprisonment generally requires a valid court order or warrant, and the direct transfer of prisoners without proper judicial review or authorization could contravene domestic statutes. Falana argues that executing such transfers under the pact without legislative oversight or judicial approval may itself be illegal, creating a scenario in which both the principle of legality and procedural fairness are compromised.
The potential for conflicting obligations between international commitments and domestic law underscores the broader risk that implementing the agreement without proper safeguards may generate legal uncertainty and expose the government to litigation.
Lack of Legislative and Public Scrutiny
Falana also underscores the procedural deficiencies surrounding the agreement, noting that it was announced publicly during the state visit without any evidence of debate or scrutiny in Nigeria’s National Assembly. He frames this omission as a violation of democratic norms, arguing that treaties affecting citizens’ fundamental rights require not only legislative domestication but also public engagement. The absence of parliamentary debate prevents lawmakers from analyzing the provisions, raising questions about accountability and transparency in the negotiation and implementation of international agreements.
Falana’s position reinforces the principle that diplomacy and policy cannot override constitutional mandates, and that public consent and legislative input are essential components of lawful governance.
Implications of Falana’s Arguments
The legal and human rights implications of Falana’s critique are far-reaching. Firstly, until the Migration Partnership Agreement is formally domesticated by Nigeria’s National Assembly, it cannot be enforced in Nigerian courts, and any deportation carried out in its name could be legally contested. Secondly, if the agreement is implemented prematurely, Nigerians may be subjected to removal without due process, violating both constitutional rights and international human rights standards. Thirdly, the potential for legal challenges is substantial, as courts could be asked to determine whether aspects of the agreement are unconstitutional, unlawful, or inconsistent with domestic statutes.
Falana’s scrutiny places the onus on the government to ensure that enforcement mechanisms comply fully with legal requirements, protect human dignity, and uphold Nigeria’s obligations under both domestic and international law.
Falana’s Calls for Action
In response to these concerns, Femi Falana has outlined specific actions that he believes are necessary before the agreement can be operationalized. These include a comprehensive review of the pact, the domestication of its provisions through proper legislation, and the incorporation of clear human rights protections for Nigerians who may be affected by deportation or prisoner transfers. He stresses that safeguards must be explicit, accessible, and enforceable, ensuring that citizens have the ability to challenge removal orders, verify documentation, and maintain family integrity.
His calls highlight the broader principle that international agreements should complement, rather than circumvent, domestic constitutional protections and social realities.
What Happens Next
At present, the UK–Nigeria Migration Partnership Agreement remains primarily a political and diplomatic commitment announced during a state visit. Its domestic legality is under scrutiny, and the legal opinions expressed by Femi Falana signal that implementation without proper legislative domestication could provoke constitutional challenges. Should activists, civil society organizations, or affected citizens pursue litigation, Nigeria’s judiciary may be asked to rule on the constitutionality of the agreement and the permissibility of using informal documents in deportation procedures.
The outcome of such legal challenges could set important precedents for how Nigeria negotiates and implements international agreements that affect citizens directly.
Closeout
Femi Falana’s public critique of the UK–Nigeria Migration Partnership Agreement is a profound examination of the intersection between international diplomacy, constitutional law, and human rights protection. It emphasizes that while governments may seek to expedite migration processes or fulfill diplomatic objectives, the rule of law and the rights of citizens must remain paramount.
The questions he raises—about due process, constitutional domestication, human rights obligations, family integrity, and procedural safeguards—are not merely theoretical but have immediate and tangible implications for Nigerians living in the UK. As Nigeria navigates the legal and political dimensions of this agreement, Falana’s scrutiny serves as a vital reminder that law, fairness, and respect for human dignity cannot be sidelined in the pursuit of expediency or international partnership.
The unfolding legal discourse will likely shape the future of migration governance in Nigeria and serve as a reference point for how treaties and bilateral agreements are approached within the framework of constitutional democracy.
