A/68/44 Training (16) The Committee is concerned that no specific methodologies exist to evaluate the efficiency of training or educational programmes for law enforcement and medical personnel, judges and prosecutors, as well as persons working with migrants and asylum seekers on the absolute prohibition of torture and ill-treatment (art. 10). The State party should: (a) Develop specific methodologies to evaluate the training and educational programmes provided on the absolute prohibition of torture and ill-treatment to law enforcement and medical personnel, judges and prosecutors, as well as persons working with migrants and asylum seekers; (b) Ensure that the Istanbul Protocol is made a mandatory part of the training for all medical professionals involved in the documentation and investigation of allegations of torture and ill-treatment in order to permit, inter alia, the proper diagnosis of signs of torture. Conditions of detention (17) The Committee is concerned by information suggesting that conditions in some prisons and police arrest houses do not meet international standards, including with regard to infrastructure, hygiene and sanitary conditions, hot water, heating, windows, ventilation, lighting, furniture and living space. It is concerned that unsatisfactory conditions have also been reported by the Chancellor of Justice in some new or renovated facilities. The Committee is particularly concerned by the use of cells with unsuitable conditions in some police stations. It is also concerned by the failure of the prison authorities to ensure the right of prisoners to have their complaints about the conditions of detention heard (arts. 2, 11, 12, 13 and 16). The State party should: (a) Take immediate steps to improve the material conditions in all prisons and police arrest houses, including newly built and renovated ones, with a view to improving the infrastructure, hygiene and sanitary conditions, hot water, heating, ventilation, lighting and furniture, and repairing broken windows, in accordance with international standards; (b) Take steps to ensure minimum international standards of at least four square meters of living space for each detainee; (c) Ensure that the construction of planned additional prisons and the expansion and renovation of existing places of detention continue according to schedule; (d) Ensure the existence of impartial mechanisms to deal with the complaints of prisoners about their conditions of detention and provide effective follow-up to such complaints. Categorization of prisoners according to their language proficiency (18) The Committee is concerned by reports that since 2011, prisoners’ name badges include information about their proficiency in the Estonian language, which some consider to be discriminatory and humiliating (arts. 2, 11 and 16). The Committee recommends that the State party put an end to any discrimination against prisoners on the basis of their proficiency in the Estonian language and ensure that prisoners are not penalized with regard to administrative or disciplinary matters if they do not have a sufficient understanding of the language.
