Niger’s failure to protect Hadijatou Mani Koraou shows how a private act of enslavement can become a state’s international responsibility. The ECOWAS Court held that a government may be answerable when its courts and officials know of slavery and fail to provide effective protection. For East African advocates, the case offers a practical method: prove the conditions of control, identify what state institutions knew, and explain the legal steps they could have taken.

The facts and the domestic proceedings

Dame Hadijatou Mani Koraou c. La République du Niger (ECW/CCJ/APP/08/08; ECW/CCJ/JUD/06/08) [2008] ECOWASCJ 6 (27 October 2008) is one of the most important African regional decisions on contemporary slavery. The Court of Justice of the Economic Community of West African States (ECOWAS Court) decided the case in Niamey. The published judgment lists Judges Sanogo, Nana and Tall. It records no dissenting opinion, so the decision should be read as the Court’s judgment rather than as a split-panel ruling.

Hadijatou Mani was born into a community where hereditary status shaped social relations. In 1996, when she was about twelve, she was sold to El Hadj Souleymane Naroua for 240,000 CFA francs. She was placed in his household and subjected over many years to forced domestic and agricultural work, sexual exploitation, violence, humiliation and control over her movement. Naroua later gave her a paper describing her as freed. The paper did not undo the conditions she had experienced or restore her ability to choose her life. Its very existence pointed to the power that one person claimed to exercise over another.

In 2005, after leaving the household, Mani sought recognition that she was free and protection against being returned. A local court treated the relationship through a marriage framework and made statements that accepted a slave status as a possible social fact. The Niger Supreme Court later quashed the local ruling because of a defect in the court’s composition. It did not decide whether Mani had been enslaved or whether the alleged owner should be prosecuted under Niger’s anti-slavery provisions. This distinction mattered: a procedural reversal corrected the defect in the proceedings but left the underlying protection question unanswered.

Mani then brought her claim against Niger before the ECOWAS Court. She did not ask the regional court to impose criminal punishment on Naroua as though he were a party in a domestic prosecution. Her claim focused on the State’s own responsibility: whether Niger had failed to protect her from slavery despite laws prohibiting it and despite the circumstances becoming visible to public authorities. The Court accepted that she had standing and rejected the State’s objection that she first had to exhaust local remedies. This opened the way to a merits decision about the conduct of the State.

The question before the ECOWAS Court

The central legal question was whether Niger had breached its international obligations by failing to protect Mani from slavery and by allowing state institutions to treat the alleged enslavement as a private or customary matter. A connected question was whether the Court could hear the case when the national proceedings had not produced an effective answer. These are two distinct questions. The first concerns responsibility on the merits. The second concerns access to the regional forum. The judgment’s value is clearer when the two are not collapsed into one.

The legal materials included the African Charter on Human and Peoples’ Rights, the 1926 Slavery Convention and Niger’s own Penal Code as amended in 2003 to criminalise slavery. The Court drew on the accepted international understanding of slavery, which centres on powers attaching to ownership being exercised over a person. The test does not depend on a bill of sale or a formal declaration that someone is property. It asks what control the person actually faced: whether they could leave, refuse work, choose relationships, control their body or live without the other person’s claimed authority.

That functional approach makes the legal question understandable to a reader without specialist training. A person can be unfree even if the law does not recognise legal ownership. A customary label, marriage certificate, household arrangement or paper of “liberation” cannot settle the question if the evidence shows coercion and domination. The Court had to decide not only whether the law prohibited slavery in theory, but whether state conduct gave that prohibition practical effect in Mani’s life.

The decision and the rule of law

The ECOWAS Court found that Mani had been a victim of slavery and that Niger had failed to fulfil its duty to protect her. The Court did not hold that every private wrong automatically becomes a treaty breach. Its reasoning connected private conduct with the State’s positive obligation to take reasonable and effective measures when it knows, or ought to know, that a fundamental right is at risk. An official’s failure to apply a clear anti-slavery law, particularly when a court was confronted with facts pointing to slavery, can therefore make the State internationally responsible.

The rule of law may be stated this way: where a State has undertaken to prohibit slavery, it must use its laws and institutions to identify, prevent, investigate and remedy slavery in practice; it cannot avoid responsibility by describing coercive control as a private arrangement or a custom. A paper stating that the victim has been freed is not an adequate substitute for protection, accountability and a remedy. Nor is a procedural correction enough if the essential rights question remains unexamined and the person remains at risk.

The judgment also matters for access to justice. Niger argued that local remedies had not been exhausted and that national proceedings were still pending. The Court did not treat that objection as an automatic bar. It examined the situation and recognised that local remedies need not be pursued indefinitely where they are unavailable, ineffective or unduly prolonged. This is not permission to bypass national courts whenever a claimant prefers a regional forum. It is a reminder that the exhaustion requirement exists to give the State a fair chance to provide a real remedy, not to trap a victim in procedures that cannot address the violation.

The Court held Niger responsible for the inaction of its administrative and judicial authorities and awarded Mani 10 million CFA francs. The monetary remedy recognised that the harm was not merely an abstract violation of international law. It was an injury to a person who had been deprived of liberty and dignity over a prolonged period. Compensation, however, could not itself undo the years of abuse. The broader remedy was the Court’s explicit recognition that slavery had occurred and that the State’s failure to act mattered in law.

What the advocates made legally visible

The judgment names Abdourahaman Chaïbou-Nanzir as local counsel and records the assistance of Helena Duffy and Ibrahima Kane of INTERIGHTS. Their advocacy, together with Mani’s own testimony and witnesses, kept the focus on the State’s omissions. The case was advanced for Mani before the ECOWAS Court, and its key achievement was to connect the facts to Niger’s law, the African Charter and the State’s international duty to protect. A claim framed solely as a dispute between Mani and Naroua risked being treated as a private status or marriage dispute. The lawyers instead connected the facts to Niger’s legislation, the African Charter and the State’s international duty to protect. That framing gave the Court a clear legal path to find responsibility without having to decide Naroua’s criminal guilt in his absence.

The evidentiary approach was also instructive. The facts were not reduced to the old-fashioned question whether a document proved formal ownership. Duration, age, payment, labour, sexual exploitation, physical abuse, confinement and control of movement combined to show how power operated. A strong advocate in a comparable case would organise evidence around the elements of control rather than rely on labels. Witness accounts, medical records, communications, official files, employment arrangements, movement restrictions and the victim’s own description can each help reconstruct a pattern that otherwise may be dismissed as “custom” or “family life.”

The applicant’s account also made the State’s knowledge question concrete. Courts had heard a dispute in which the evidence suggested the applicant had been sold and controlled. A judge’s response to those facts could not be treated as legally neutral simply because the proceeding began as a status or domestic dispute. Where national law already prohibits the conduct, a court should identify the criminal or protective dimension, ensure the affected person can speak safely, and refer the matter to competent authorities when necessary. The Court criticised the domestic handling because it normalised rather than challenged the applicant’s status.

For counsel, a possible weakness in many similar cases is failing to separate available remedies from effective remedies. The applicant should create a dated record of each complaint, the authority approached, the response received, steps delayed and any present risk. That record helps answer an exhaustion objection with particulars. It also helps distinguish an ordinary appeal still capable of providing protection from a process that has stalled or has itself reinforced the harmful condition. Mani’s case demonstrates the importance of showing the regional court exactly why the national path failed to address the core rights question.

The record should also distinguish relief against the alleged perpetrator from relief against the State. A victim may seek prosecution, protection, compensation, recognition of status, access to services or reform of a practice. Each remedy has a different legal route. Pleading them distinctly helps a court see the State’s acts and omissions rather than making it appear that an international tribunal is being asked to conduct a domestic criminal trial. It reduces the risk that a strong human-rights claim is dismissed because the relief is imprecisely framed.

Why the case matters in East Africa

Niger is not an East African State, and the ECOWAS Court is not the East African Court of Justice. Koraou is therefore not binding precedent in East Africa simply because its reasoning is persuasive. Its relevance comes from shared instruments and shared legal questions. The African Charter applies across East African Community Partner States. Article 5 prohibits slavery, the slave trade, torture and cruel, inhuman or degrading punishment and treatment. Article 18(3) calls on the State to eliminate discrimination against women and protect the rights of women and children. Article 1 requires States Parties to recognise the Charter rights and adopt measures to give them effect. The ECOWAS judgment helps explain what effective protection can require in practice.

National constitutions provide a more immediate legal route. Uganda’s Constitution protects every person from slavery and servitude under Article 25, provides for a fair hearing under Article 28, and protects freedom of speech and expression under Article 29. Kenya’s Constitution protects dignity in Article 28 and prohibits slavery, servitude and forced labour in Article 30. Rwanda’s Constitution protects human dignity and prohibits slavery and servitude, while the national criminal law supplies offences and procedures. These guarantees should be read with the African Charter and, where relevant, the Protocol to the African Charter on the Rights of Women in Africa. The exact remedy depends on the facts and the procedural setting in each country.

The comparison is especially useful where a survivor’s circumstances are hidden behind household or work arrangements. A person may appear to be a domestic worker, spouse, dependent relative, migrant worker or apprentice, yet the factual indicators may show forced labour or trafficking. The correct question is not whether the arrangement has a familiar local label. It is whether the person could leave, refuse, control wages, retain identity documents, move freely and access authorities without fear. Koraou supplies a disciplined way of asking those questions without presuming that poverty or informal work alone equals slavery.

East African advocates may also use the judgment when assessing state responsibility for private abuse. Human-rights duties are not limited to refraining from direct abuse by public officers. A State can breach its obligations where it fails to use reasonable legal and institutional measures to protect people against serious harm by private actors. The precise threshold varies by right and instrument, but Koraou shows why proof of notice, available law, official response and continuing risk should be gathered together. The failure to prosecute is not, by itself, always proof of a Charter violation; the case turns on the whole record and the State’s protective response.

There is a regional forum distinction too. The East African Court of Justice’s human-rights jurisdiction has developed through interpretation of the Treaty for the Establishment of the East African Community, especially the principles of good governance, democracy, the rule of law and human rights in Articles 6(d) and 7(2). In James Katabazi and Others v Secretary General of the East African Community and Attorney General of Uganda, Reference No. 1 of 2007, the EACJ held that it could examine whether a Partner State’s conduct breached Treaty principles even though it did not have a general human-rights jurisdiction under Article 27(2). Koraou and Katabazi share an important lesson: frame the claim through the mandate of the particular regional body and the State’s treaty obligations, rather than assuming that every regional court can hear every rights claim in the same way.

Later decisions and practical lessons

Koraou fits within a broader African movement toward examining the real conditions behind formal status. In its later Endorois decision, the African Commission examined how State control over ancestral land affected a community’s ability to practise religion, maintain culture and benefit from resources. The facts and rights differ, but both matters reject the idea that official labels are enough. A State’s description of an arrangement as lawful, beneficial or customary does not conclude the human-rights inquiry when the lived effect is deprivation and exclusion.

The African Court’s later Ogiek judgment, African Commission on Human and Peoples’ Rights v Kenya, Application No. 006/2012, Judgment of 26 May 2017, offers a further regional comparison. It treated an indigenous community’s relationship to ancestral land as central to rights guaranteed under the Charter. That case is not an extension of Koraou’s slavery holding. It demonstrates a broader method: identify the affected person or community, state the concrete interference, map the treaty right, and test what the State did to protect or justify it. Keeping that distinction clear prevents an advocate from treating very different harms as if they were legally identical.

For an East African advocate handling a forced-labour or trafficking claim, the practical lesson is to build the case in four linked stages. First, state the facts in a short chronology that shows how control began and continued. Second, identify the applicable national offences and constitutional rights, along with the regional or international obligations. Third, prove what authorities knew and what action they could reasonably have taken. Fourth, explain why the remedy requested fits the forum. This sequence lets an ordinary reader follow the case and gives the judge a workable legal test.

A State’s response should be evaluated with equal care. Investigators should not treat the victim’s departure from an abusive situation as proof that the danger has ended. Prosecutors should consider whether the evidence supports offences beyond a narrow assault charge. Courts should avoid language that treats a person’s enslavement as acceptable by virtue of marriage, custom or economic dependence. Administrative agencies should provide safety, interpretation, shelter or referral where necessary. These are practical steps, not abstract aspirations: each can determine whether a victim can participate in proceedings and whether evidence is preserved.

The judgment should not be overstated. It does not establish that regional courts replace national criminal courts, that every lapse by a police officer automatically creates international responsibility, or that every worker experiencing poor conditions is legally enslaved. It also does not make the ECOWAS Court’s decisions binding in East Africa. Its persuasive force is strongest where there is evidence of severe control, a clear protective duty, state notice and an inadequate institutional response. An honest case analysis states those boundaries because they make the principle more useful, not less.

Conclusion

The enduring lesson of Dame Hadijatou Mani Koraou c. La République du Niger is that a legal prohibition must reach the person it is meant to protect. The ECOWAS Court recognised that the State could be responsible where slavery was visible to its institutions and those institutions failed to use the law to end it. For East African readers, the case is a persuasive guide to proving actual control, establishing state knowledge, addressing exhaustion of remedies and choosing the correct regional pathway. The rule is simple enough to understand: a government cannot meet its duty by writing a prohibition into law and then leaving a person unprotected when the facts are brought before its courts.
