There is also case law of the European Court of Human Rights relevant to right to truth.[4] In Cyprus v. Turkey (2001), the ECtHR ruled against Turkey in the case of Greek Cypriots who had been last seen in the custody of Turkish troops. The anguish of surviving relatives constituted a "continuing violation of Article 3 of the European Convention on Human Rights (ECHR) with respect to the relatives of the Greek-Cypriot missing persons."[23] In El-Masri v. Macedonia (2012), the ECtHR established that North Macedonia had violated the Convention in allowing El-Masri to be taken into US custody during extraordinary rendition.
