CAT/C/CZE/CO/6 concerned that Roma children remain overrepresented in specialized educational programmes for children with mild mental disabilities (arts. 2, 10, 12–13 and 16). 25. Recalling its previous recommendation (see CAT/C/CZE/CO/4-5, para. 14), the Committee calls on the State party to strengthen its efforts to eradicate the segregation of Roma children in its educational system, and ensure that the decision to place Roma children in educational programmes is not adversely influenced by their Roma identity. Hate crimes against minority groups, including Roma and Muslims 26. While noting the launching of the Campaign against Racism and Hate Violence and the training of police officers on investigating hate crimes, the Committee remains concerned at the continued occurrence of hate crimes against minorities, including the Roma and Muslim communities, and at the xenophobic statements endorsed by some politicians, including members of parliament (arts. 2, 12–14 and 16). 27. The Committee urges the State party to publicly condemn threats and attacks against minority groups, including the Roma and Muslim communities, and to refrain from endorsing, through action or omission, such attacks by ensuring: (a) Prompt, thorough and effective investigations of all threats and attacks targeting these groups, including any alleged discriminatory motives that may provoke these actions, and guaranteeing that those responsible are tried and punished in accordance with the gravity of their acts; (b) Effective training of law enforcement officials and the judiciary on hatemotivated crimes and the systematic monitoring of such crimes; (c) Awareness-raising measures to counter prejudice and stereotypes, and policies to combat and prevent racially motivated crimes and discrimination. Involuntary sterilization 28. The Committee is concerned that the State party has failed to establish an extrajudicial mechanism to provide effective reparation to all persons who were subjected to involuntary sterilization, particularly Roma women. It regrets that the only means for victims of involuntary sterilization to obtain such reparation is through a legal action that is subject to a three-year statute of limitations, and that many such cases have already been time-barred (arts. 2, 14 and 16). 29. Recalling its previous recommendation (see CAT/C/CZE/CO/4-5, para. 13), the Committee calls on the State party to promptly, impartially and effectively investigate all allegations of involuntary sterilization of Roma women, and prosecute and, if found responsible, punish perpetrators. The State party should establish an extrajudicial compensation mechanism through which victims of involuntary sterilization have access to fair and adequate redress, and consider extending the time limit for filing compensation claims. Redress 30. The Committee regrets the absence of disaggregated statistical data concerning compensation provided to victims of torture and ill-treatment, including victims of involuntary sterilization, surgical castration, ill-treatment in psychiatric settings, attacks against minorities, trafficking and domestic and sexual violence. It is also concerned about the time limit set for filing complaints under the State Liability Act (No. 82/1998) (art. 14). 31. The State party should provide the Committee with data on the total number of requests for compensation received, the number of requests granted and the amount of the compensation awarded by courts. It should consider extending the time limit for filing claims under the State Liability Act, in order to allow victims to obtain fair and adequate compensation. The Committee draws the State party’s attention to its general comment No. 3 (2012) on the implementation of article 14, in which it elaborates on the nature and scope of the State parties’ obligations under article 14 of 6
