CAT/C/SRB/CO/1 page 7 (b) Improve the material conditions of detention in places of deprivation of liberty, in particular with respect to hygienic conditions and medical care, including giving access to independent medical personnel on a systematic basis. In this regard, it is important that the State party ensure that the Ministry of Health monitor the exercise of professional duties of medical staff in prisons; and (c) Set up a system of inspection of the conditions of imprisonment by independent experts, as previously reiterated by the Committee in its recommendation under its article 20 report.
