CAT/C/NLD/CO/5-6 Data collection 30. In light of its previous concluding observations (para. 17), the Committee regrets the State party’s response ‘that the Government is unable to provide information as data are not registered in a way that would allow the production of the statistics’ (para. 89 of the report) on complaints, investigations, prosecutions, convictions and sanctions of cases of torture and ill treatment by law enforcement, security, military and prison personnel. The Committee observes with concern the State party’s response that the law does not allow for the collection of such data (arts. 2, 12, 13 and 16). The Committee recommends that the State party: (a) Establish a national system for the collection of data including through research studies to facilitate analysis of the implementation of the Convention; (b) Provide the Committee with detailed statistical data, disaggregated by crime, ethnicity, age and sex, relevant to the monitoring of the implementation of the Convention at the national level, including data on complaints, investigations, prosecutions, convictions and penal or disciplinary sanctions of cases of torture and ill-treatment by law enforcement, security, military and prison personnel, domestic and sexual violence, crimes with racist motives, ethnic composition of the detainee population including the representation therein of Antilleans, Moroccans, Roma, Sinti and Turks, as well as on means of redress, including compensation and rehabilitation provided to the victims. 31. The Committee is also concerned about the lack of updates in the report, due to privacy concerns, on the asylum applications, including their outcomes. The Committee reiterates its recommendation that, in order to have a clearer view of the situation regarding protection against torture, the State party include in its future reports, data which are disaggregated by age, sex and ethnicity on: (a) The number of asylum applications registered and the number of applications processed respectively under the normal and accelerated procedures; (b) The number of applications accepted; (c) The number of applicants whose applications for asylum were accepted on grounds that they had been tortured, or might be tortured if returned to their country of origin, as well as data on asylum granted on grounds of sexual violence; (d) The number of cases of refoulement or expulsion. Other issues 32. The Committee invites the State party to ratify the core United Nations human rights treaties to which it is not yet a party, including the Convention on the Rights of Persons with Disabilities and the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, and to consider signing and ratifying the Optional Protocol to the Convention on the Rights of Persons with Disabilities, the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights and the Optional Protocol to the Convention on the Rights of the Child on a communications procedure. 33. 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. 34. 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). 11
