CAT/C/GRC/CO/5-6 The State party should strengthen its efforts in respect of redress, including compensation and the means for as full rehabilitation as possible, and develop a specific programme of assistance in respect of victims of torture and ill-treatment. The State party should also establish more efficient and accessible procedures to ensure that victims can exercise their right to compensation in accordance with Law 3811/2009, especially by reducing the time used by domestic courts to award damages in such cases. The Committee also recommends that the State party should without exception and as a matter of urgency offer prompt redress to victims of violence which has been determined by international supervisory organs and courts, such as this Committee and the Human Rights Committee, and the European Court of Human Rights. Aghia Varvara case 27. The Committee reiterates its previous concern that 502 out of 661 Albanian Roma street children reportedly went missing following their placement during 1998-2002 in the Greek Aghia Varvara children’s institution and it is particularly concerned that these cases have not been investigated by the relevant State party authorities (arts. 2 and 12). The Committee urges the State party to engage with the Albanian authorities with a view to promptly creating an effective mechanism to investigate these cases in order to establish the whereabouts of the missing children, in cooperation with the Ombudsmen of both countries and relevant civil society organizations, and identify disciplinary and criminal responsibilities of those involved, before the passage of time creates difficulties in ascertaining the facts. The Committee also recommends that the State party adopt a comprehensive policy to combat violations of the rights of street children in order to prevent recurrences in the future. Data collection 28. While noting with interest that a special working group has recently been set up to submit a thorough proposal for the reorganization and modernization of the State party’s Justice Statistics, the Committee regrets the absence of comprehensive and disaggregated data on complaints, investigations, prosecutions and convictions of cases of torture and illtreatment by law enforcement officials, including police and prison officials and border guards, as well as on trafficking and domestic and sexual violence (arts. 11 and 12). The State party should establish an effective system to compile statistical data relevant to the monitoring of the implementation of the Convention at the national level, including data on complaints, investigations, prosecutions and convictions of cases of torture and ill-treatment, trafficking and domestic and sexual violence, as well as on means of redress, including compensation and rehabilitation, provided to the victims. 29. The Committee invites the State party to ratify the core United Nations human rights treaties to which it is not yet a party, namely the International Convention on the Protection of the Rights of All Migrant Workers and Members of their Families, the Convention on the Rights of Persons with Disabilities, and the International Convention for the Protection of All Persons from Enforced Disappearance. 30. The State party is requested to disseminate widely the report submitted to the Committee and the Committee’s concluding observations, in appropriate languages, through official websites, the media and non-governmental organizations. 31. The State party is invited to submit its common core document, in accordance with the requirements of the common core document contained in the harmonized guidelines on reporting under the international human rights treaties (HRI/GEN/2/Rev.6). 9
