CAT/C/CZE/CO/6 cases are investigated and, on a finding of criminal responsibility, lead to a penalty proportionate to the gravity of the offence. The State party should also ensure detection, monitoring and protection of vulnerable detainees with a risk of suicide, and provide them with appropriate assistance, including psychiatric care and other preventive measures; (f) Ensure adequate access to health services, free of charge, and to interpretation services during medical examinations or consultations, if needed; (g) Consider allowing non-governmental organizations (NGOs) to regularly monitor all places of detention to complement the monitoring undertaken by the national preventive mechanism. Situation of asylum seekers and other foreign nationals 20. The Committee is concerned at the State party’s practice of detaining individuals seeking international protection, including those in particularly vulnerable situations, and at the lack of alternative accommodation for families. Taking into account the fact that the Asylum Act prohibits the detention of asylum-seeking children, the Committee is particularly concerned that families with children continue to be detained at the BěláJezová facility, often for periods of more than two months. The Committee regrets that persons detained at immigration detention centres lack adequate access to free legal assistance, resulting in low levels of awareness of their rights to apply for asylum, or to appeal against a negative decision. It is also concerned at reports of the absence of a standard operating procedure to identify and protect persons in vulnerable situations, the use of excessive force, such as indiscriminate handcuffing when expelling foreign nationals, and the obligation of foreign nationals awaiting deportation to pay for their detention (arts. 3, 11 and 16). 21. The State party should take all the measures necessary to: (a) End the practice of detaining persons in need of international protection, particularly children, and ensure the provision of alternative accommodation for families with children; (b) Continue its efforts to improve material conditions in reception centres and detention facilities, including with regard to provision of basic necessities, healthcare services and educational and recreational opportunities for children; (c) Provide free legal assistance at all reception and detention centres, and facilitate access to those places by NGOs providing legal assistance; (d) Develop and implement a standard procedure for the identification and protection of persons in vulnerable situations, including victims of torture and illtreatment; (e) Review the policy of obliging detained foreigners awaiting deportation to pay for their detention, with a view to abolishing it. Stateless persons 22. The Committee is concerned at the absence of a legal definition of statelessness in the domestic legislation, and the lack of a separate mechanism to identify and protect stateless persons, who need specific procedural safeguards (art. 3). 23. The State party should introduce a definition of statelessness into its domestic legislation. It should also establish a dedicated statelessness determination procedure, provide stateless persons with identification documents, and create a central database of stateless persons in its territory. Inclusion of Roma children 24. While noting the measures taken by the State party to implement the decision of the European Court of Human Rights in D.H. and others v. the Czech Republic, and the increase in the number of Roma children in mainstream education, the Committee is 5
