CAT/C/KAZ/CO/2 page 12 Trafficking in human beings 31. While noting with satisfaction legislative measures taken in the field of trafficking in human beings and the adoption of a National Plan of Action on Trafficking for 2006-2008, the Committee remains concerned at the prevalence of the phenomenon in the State party (arts. 2, 7, 12 and 16). As recommended by the Committee on the Elimination of Discrimination against Women in 2007 (CEDAW/C/KAZ/CO/2, para. 18), the State party should ensure that legislation on trafficking is fully enforced and that the National Plan of Action is fully implemented. The State party should also continue its efforts to investigate, prosecute, convict and punish persons found responsible, including government officials complicit in trafficking. Data Collection 32. While noting that some statistics have been provided, the Committee regrets the lack of comprehensive and disaggregated data on complaints, investigations, prosecutions and convictions of cases of torture and ill-treatment by law enforcement officials, as well as on the incidence of trafficking and sexual violence and on the number of prosecutions of persons in this connection. The Committee notes also the insufficient information on the training provided to law enforcement officials as regards the provisions of the Convention. The State party should provide detailed statistical data in its next periodic report, disaggregated by gender, ethnicity or nationality, age, geographical region and type and location of place of deprivation of liberty, on complaints related to cases of torture and other ill-treatment, including those rejected by the courts, as well as related investigations, prosecutions and disciplinary and penal sanctions, and on the compensation and rehabilitation provided to the victims. The State party should also provide further information on the incidence of trafficking and sexual violence, as well as on training provided to all State’s officials regarding the provisions of the Convention. 33. The State party is encouraged to consider becoming a party to 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, and the Convention on the Rights of Persons with Disabilities. The State party is also encouraged to ratify the International Convention for the Protection of All Persons from Enforced Disappearance. 34. The Committee invites the State party to submit its core document in accordance with the requirements of the common core document in the harmonized guidelines on reporting, as approved by the international human rights treaty bodies and contained in document HRI/GEN/2/Rev.5. 35. The State party is encouraged to disseminate widely the reports it submitted to the Committee, its replies to the list of issues and the concluding observations of the Committee, in all appropriate languages, through official websites, the media and non-governmental organizations. 36. The Committee requests the State party to provide, within one year, information on its response to the Committee’s recommendations contained in paragraphs 7, 9, 18 and 29 above.
