CAT/C/GRC/CO/7 Committee also takes note of the information provided by the delegation on the deinstitutionalization policies recently adopted by the State party (arts. 11 and 16). 39. The State party should: (a) Ensure that means of restraint are used only as a last resort to prevent the risk of harm to the individual or others and only when all other reasonable options would fail to satisfactorily contain the risk; (b) Ensure that involuntary psychiatric hospitalization is strictly necessary and proportionate and is applied as a measure of last resort and under the effective supervision and independent monitoring of judicial organs; (c) Ensure legal safeguards for persons hospitalized involuntarily in psychiatric institutions, including the provision of legal representation and the right to be heard in person by the judge, the judicial tribunal or the board ordering the hospitalization, and ensure that placement procedures are supported by two separate and reasoned medical opinions; (d) Ensure that there are sufficient funded mental health services in the community. Social care settings for persons with disabilities 40. Concerning the treatment of persons in social care settings, including those with psychosocial disabilities, the Committee recalls the numerous deficiencies found by the national preventive mechanism during its monitoring activities in 2018.

Training 44. While appreciating the information provided by the State party about human rights training programmes for members of the Hellenic Police and the Hellenic Coast Guard, prison staff, judges and prosecutors, the Committee is concerned at the lack of information on the evaluation of the impact of those programmes. It regrets that only scant information has been provided on training programmes for professionals directly involved in the investigation and documentation of torture and for medical and other personnel dealing with detainees on how to detect and document physical and psychological sequelae of torture and ill-treatment (art. 10). 45. The State party should: (a) Provide instruction and further develop mandatory in-service training programmes to ensure that all public officials, in particular law enforcement officials, prison staff and medical personnel employed in prisons and psychiatric institutions, are well acquainted with the provisions of the Convention, especially the absolute 10
