Quick answer
Yes. In Velásquez Rodríguez v. Honduras (judgment on the merits, 29 July 1988), the Inter-American Court of Human Rights held Honduras internationally responsible for the forced disappearance of Manfredo Velásquez. No individual officer had been convicted. The Court explained that a violation can be established even if the individual perpetrator is unknown. A State is also responsible when it fails to act with due diligence (reasonable care) to prevent, investigate and punish violations, even where the act is not directly attributable to it.
The case
Velásquez Rodríguez v. Honduras, Inter-American Court of Human Rights, judgment of 29 July 1988 (Merits). Manfredo Velásquez, a student at the National Autonomous University of Honduras, was seized by armed men in Tegucigalpa on 12 September 1981 and was never seen again. The Court found that the disappearance was carried out by agents acting under cover of public authority. It unanimously declared that Honduras had violated the rights to personal liberty (Article 7), humane treatment (Article 5) and life (Article 4) of the American Convention on Human Rights, each read with Article 1(1). Honduras was ordered to pay fair compensation to the victim's next-of-kin.
The law: Article 1(1) of the American Convention
Article 1(1) imposes two obligations on States: to respect the rights in the Convention and to ensure their free and full exercise. The Court read the duty to ensure broadly. It requires the State to organise the whole governmental apparatus so that it can legally secure human rights. As a result, the State must prevent, investigate and punish violations, and where possible restore the right and compensate the victim.
Key principles from the judgment
- Acts of public authority: any violation by public authorities, or by persons using their official position, is imputable to the State.
- Due diligence: even an act not initially imputable to the State, such as one by a private person or an unidentified person, can make the State responsible. That happens because of its lack of due diligence to prevent the violation or respond to it.
- Identity of the perpetrator is not decisive: the question is whether the violation occurred with government support or acquiescence, or whether the State allowed it without preventing it or punishing those responsible.
- A serious investigation: the duty to investigate is not breached merely because the investigation fails. However, it must be serious and "not as a mere formality preordained to be ineffective". It must not depend on the victim's family offering proof.
- Continuing duty: the duty to investigate lasts as long as the fate of the disappeared person is uncertain. The State must inform relatives of the victim's fate and, if the victim was killed, where the remains are.
- Limits: the existence of a particular violation does not, by itself, prove a failure to prevent it. Not every private crime becomes a State violation.
Example
Farhan is taken away by armed men and disappears. His family repeatedly approaches the police and the courts, but no real inquiry is made, and the officials wait for the family to produce evidence. Even if the kidnappers are never identified, the State's failure to investigate seriously can engage its responsibility under a human rights treaty that binds it. What matters is whether the State met its own duty of due diligence, not whether a particular officer was convicted.
Current-law note
The judgment remains a leading authority on positive obligations and due diligence in international human rights law. The International Convention for the Protection of All Persons from Enforced Disappearance entered into force on 23 December 2010. According to the UN Treaty Collection, India signed this Convention on 6 February 2007 but has not ratified it. India is also not a party to the American Convention; the case is studied in India as persuasive comparative authority.
Exam point
Velásquez Rodríguez v. Honduras (Inter-American Court, 1988) held that a State is responsible not only for what its agents do but also for failing, with due diligence, to prevent, investigate and punish human rights violations. A violation can be established even if the individual perpetrator is unknown.
