1. Case Citation and Basic Information
C.N. and V. v France (Application No 67724/09) was decided by the European Court of Human Rights (Fifth Section) on 11 October 2012. The Chamber was composed of Dean Spielmann (President), Mark Villiger, Karel Jungwiert, Boštjan M. Zupančič, Ann Power-Forde, Angelika Nußberger, and André Potocki, with Claudia Westerdiek serving as Section Registrar. The case concerned two sisters who alleged that they had been subjected to servitude and forced labour in France. The Court held that France had failed to provide effective protection against modern slavery, finding a violation of Article 4 of the European Convention on Human Rights. The judgment is regarded as a significant authority on States’ positive obligations to prevent exploitation, protect victims, and ensure effective criminal enforcement against human trafficking and servitude.
2. Introduction
The European Court of Human Rights (ECtHR) plays a pivotal role in safeguarding fundamental rights under the European Convention on Human Rights through the authoritative interpretation of Convention provisions. Among these, Article 4, which prohibits slavery, servitude, forced labour, and human trafficking, imposes both negative and positive obligations on States to protect individuals from exploitation.[1] C.N. and V. v France is a landmark judgment because it reinforces the duty of States to establish effective legal and institutional safeguards against modern forms of servitude. This paper examines how the ECtHR interpreted these positive obligations and addresses the following question: ‘How did the Court define States’ responsibilities under Article 4, and how has the judgment strengthened the protection of victims of modern slavery?’[2]
3. Facts of the Case
The applicants, C.N. and V., were two Burundian sisters who alleged that they had been subjected to servitude and forced labour while living with relatives in France. After arriving in France as minors, they were expected to undertake extensive domestic duties, including cleaning, cooking, childcare, and other household tasks without remuneration. Their daily lives were characterised by excessive working hours, restricted personal autonomy, limited access to education, and dependence on the household in which they lived.[3]
The applicants contended that their vulnerable immigration status and economic dependence rendered them unable to escape their exploitative circumstances. Although French authorities initiated criminal proceedings against the individuals concerned, the domestic courts concluded that the evidence was insufficient to establish criminal liability for the offences alleged under the legislation then in force.[4] Dissatisfied with the outcome, the applicants lodged an application before the European Court of Human Rights, arguing that France had failed to provide effective legal protection against servitude and forced labour. The dispute therefore required the Court to determine whether France had fulfilled its positive obligations under Article 4 of the European Convention on Human Rights to prevent exploitation and ensure effective legal remedies for victims.[5]
4. Legal Issues
The case raised fundamental questions concerning the scope and effectiveness of State obligations under Article 4 of the European Convention on Human Rights, which prohibits slavery, servitude, forced labour, and human trafficking. The principal issue was whether France had provided an adequate legal and institutional framework capable of protecting individuals from severe forms of domestic exploitation.[6] Closely connected to this was the question of whether the existing French criminal legislation offered effective protection and remedies for victims of servitude and forced labour. The case also required clarification of the legal distinctions between slavery, servitude, and forced labour, concepts that are closely related but differ in their defining characteristics and legal consequences under international human rights law.[7] More broadly, the application invited the Court to consider the extent of States’ positive obligations to prevent exploitation, investigate allegations effectively, and ensure that domestic legal systems provide practical and effective protection against contemporary forms of modern slavery.[8]
5. Arguments Presented
The applicants argued that France had violated Article 4 of the European Convention on Human Rights by failing to protect them from conditions amounting to servitude and forced labour. They contended that, despite clear indicators of prolonged domestic exploitation, the French authorities did not provide an effective legal response capable of preventing, investigating, or punishing the abuse they had endured. In their view, the criminal legislation in force at the material time was inadequate because it did not criminalise all forms of servitude and failed to offer effective remedies for victims of modern exploitation. Consequently, the applicants maintained that France had not discharged its positive obligation to secure practical and effective protection against abuses prohibited by Article 4.[9]
The French Government disputed these allegations, asserting that the domestic legal framework already contained sufficient criminal provisions to address exploitation through offences such as abuse of vulnerability and unlawful working conditions. It further argued that the applicants had access to judicial remedies, that criminal proceedings had been conducted in accordance with domestic law, and that the authorities had acted within the limits of the available evidence. Accordingly, the Government maintained that the Convention did not require any additional legislative measures and that no breach of Article 4 had occurred.[10]
The central disagreement therefore concerned not the existence of legal protections in principle, but whether those protections were sufficiently comprehensive and effective to satisfy France’s positive obligations under Article 4 in safeguarding individuals from contemporary forms of servitude and forced labour.[11]
6. Court’s Reasoning and Analysis
In its assessment, the European Court of Human Rights adopted a purposive interpretation of Article 4 of the European Convention on Human Rights, emphasising that the provision must be interpreted in light of present-day conditions and the evolving nature of modern exploitation. Rather than confining Article 4 to its historical understanding of slavery, the Court recognised that contemporary forms of servitude and forced labour often arise through coercion, vulnerability, and dependency rather than formal ownership. Consequently, the Convention requires practical and effective protection against all forms of exploitation that undermine human dignity.[12]
Central to the Court’s reasoning was the principle that States assume positive obligations under Article 4. These obligations extend beyond refraining from direct violations and require governments to establish an effective legal and institutional framework capable of preventing exploitation, protecting victims, conducting effective investigations, and ensuring that perpetrators are held accountable.[13] The Court reiterated that human rights protection cannot depend solely on the existence of legal provisions; domestic legislation must operate effectively in practice. This interpretation reflects the Convention’s broader objective of guaranteeing rights that are practical rather than merely theoretical.[14]
The Court further recognised that modern slavery frequently affects individuals in situations of heightened vulnerability, including migrants, domestic workers, and children. Such circumstances impose a heightened duty of diligence on national authorities to identify indicators of exploitation and respond promptly. By placing vulnerability at the centre of its analysis, the Court reinforced the preventive dimension of Article 4 and acknowledged that exploitation may occur through subtle forms of control rather than overt physical restraint.[15]
Examining the French legal framework, the Court questioned whether the criminal legislation applicable at the material time provided sufficient protection against servitude and forced labour. Although French law criminalised certain exploitative conduct, it did not comprehensively address all manifestations of domestic servitude. The resulting legislative gaps reduced the effectiveness of criminal prosecution and limited the protection available to victims, demonstrating that formal criminal offences alone were insufficient to satisfy Convention obligations.[16]
The Court also relied on broader European and international human rights standards, including earlier Strasbourg jurisprudence and international instruments addressing trafficking and forced labour, to interpret the scope of Article 4 consistently with contemporary human rights developments. This comparative approach reinforced the Convention’s character as a living instrument responsive to emerging forms of exploitation.[17]
Ultimately, the Court concluded that effective enforcement is indispensable to Article 4. Rights cannot be adequately protected where legislative deficiencies or weak enforcement prevent victims from obtaining meaningful justice. The judgment therefore underscores that States must combine comprehensive legislation with effective investigation, prosecution, and institutional commitment to fulfil their obligations under the Convention.[18]
7. Judgment and Ratio Decidendi
The European Court of Human Rights held that France had violated Article 4 of the European Convention on Human Rights in relation to the first applicant, C.N., after concluding that the domestic legal framework had failed to provide effective protection against servitude and forced labour. The Court found that, although French law criminalised certain forms of exploitation, the legislation applicable at the material time did not adequately address the particular circumstances of domestic servitude, thereby limiting the effectiveness of criminal prosecution and victim protection.[19] In contrast, the Court found no violation in respect of the second applicant, V., as the evidence did not establish that her circumstances reached the threshold required under Article 4.[20] The Court further awarded just satisfaction to the first applicant under Article 41 of the Convention for the non-pecuniary damage resulting from the violation.[21]
The judgment was founded on the principle that Convention rights must be practical and effective rather than theoretical or illusory. The ratio decidendi established that States have a positive obligation under Article 4 to adopt and enforce a comprehensive legal framework capable of preventing, investigating, prosecuting, and punishing practices amounting to servitude and forced labour. Merely maintaining general criminal offences is insufficient where those provisions fail to provide effective protection against contemporary forms of exploitation.[22]
8. Critical Analysis
The judgment in C.N. and V. v France represents a significant advancement in the protection of individuals vulnerable to modern forms of exploitation. Its principal strength lies in the Court’s progressive interpretation of Article 4, recognising that servitude and forced labour extend beyond traditional notions of slavery and require legal responses that reflect contemporary realities. By emphasising the positive obligations of States to prevent, investigate, and punish exploitative practices, the Court reinforced the principle that human rights protection must be practical and effective rather than merely theoretical.[23] The decision has therefore strengthened the legal framework for combating human trafficking and domestic servitude across Europe.
Nevertheless, the judgment is not without limitations. Although the Court acknowledged the interconnected nature of slavery, servitude, and forced labour, it provided only limited guidance on the precise legal boundaries between these concepts. This continuing ambiguity may create uncertainty for domestic courts when classifying exploitative conduct. Furthermore, while the judgment requires States to establish effective legal frameworks, it offers relatively little direction on the institutional measures necessary to ensure consistent implementation in practice. Consequently, the effectiveness of Article 4 protection continues to depend largely on national political commitment and enforcement capacity.[24]
From a comparative perspective, the judgment builds upon Siliadin v France, which first recognised that States bear positive obligations to criminalise and effectively sanction practices amounting to servitude.[25] It also complements Rantsev v Cyprus and Russia, where the Court expanded Article 4 protection by recognising human trafficking as falling within its scope and by strengthening States’ duties to prevent exploitation through effective cooperation and investigation.[26] C.N. and V. v France further develops this jurisprudence by reinforcing the requirement that domestic legal systems must provide comprehensive and effective protection against evolving forms of exploitation. In my view, the judgment strikes an appropriate balance between doctrinal development and practical human rights protection, although greater conceptual clarity would enhance its long-term value for national courts and legislators.
Conclusion
C.N. and V. v France reaffirmed that Article 4 of the European Convention on Human Rights requires States to provide practical and effective protection against servitude and forced labour through robust legislation and effective enforcement. The Court found a violation of Article 4 in respect of the first applicant, awarding EUR 30,000 in non-pecuniary damages under Article 41, while finding no violation concerning the second applicant.[27] As a Chamber judgment, it was not subsequently referred to the Grand Chamber and therefore became final in accordance with Article 44 of the Convention.[28] Its lasting impact lies in strengthening States’ positive obligations and influencing subsequent anti-trafficking jurisprudence. Future legal development should focus on clearer distinctions between forms of exploitation and more effective domestic implementation. In my view, the judgment remains a cornerstone of European human rights law because it prioritises meaningful protection over purely formal legal guarantees.[29]
