A/66/44 prevent and combat such phenomena, including medical, social and rehabilitative measures (arts. 2, 4 and 16). The State party should combat trafficking in human beings through the adoption and implementation of specific anti-trafficking legislation ensuring that trafficking is defined as a crime in the State party in accordance with international standards. These offences should be punishable by appropriate penalties. The State party should provide protection for victims and ensure their access to medical, social, rehabilitative, counselling and legal services. Discrimination and violence against vulnerable groups (25) The Committee is concerned at reports that vulnerable groups such as lesbian, gay, bisexual and transgender (LGBT) persons are subjected to discrimination and ill-treatment, including sexual violence, both in public and domestic settings (arts. 2 and 16). The State party should investigate crimes related to discrimination directed towards all vulnerable groups and pursue ways in which hate crimes can be prevented and punished. The State party should also promptly, thoroughly and impartially investigate all cases of discrimination and ill-treatment of these vulnerable groups, and punish those responsible for these acts. The State party should conduct awareness-raising campaigns for all officials who are in direct contact with victims of such violence, as well for the population at large. Situation of “Bidun” persons (26) The Committee expresses its concern at the situation of at least 100,000 people, who are not legally recognized by the State, known as the “Bidun” (without nationality) and who are allegedly victims of various types of discrimination and ill-treatment (art. 16). The State party should enact specific legislation in order to protect “Bidun” people and recognize their legal status. The State party should adopt all adequate legal and practical measures to simplify and facilitate the regularization and integration of these persons and their children. It should ensure that these persons enjoy all human rights without discrimination of any kind. The State party should also adopt the necessary measures to guarantee that these persons are informed of their rights in a language they understand and have access to the fundamental legal safeguards from the moment they are deprived of their liberty, without any discrimination. National human rights institution (27) The Committee notes with concern that the State party has not yet established a national human rights institution to promote and protect human rights in the State party, in accordance with the principles relating to the status of national institutions for the promotion and protection of human rights (the Paris Principles) (General Assembly resolution 48/134, annex) (art. 2). The State party should establish an independent national human rights institution, in accordance with the Paris Principles. Data collection (28) 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, security, intelligence and prison personnel, as well as on trafficking, ill-treatment of migrant workers, and domestic and sexual violence. The State party should 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, 106 GE.11-45568
