A/HRC/31/57/Add.3 (j) Make publicly available reliable information on the number of perpetrators from the previous regime that have been prosecuted and sentenced, and how these persons are being treated in the special prison where they are held. 115. With regard to conditions of detention, the Special Rapporteur recommends that the Government: (a) Take steps, in law and in practice, to increase the number of hours all categories of inmates are allowed access to open areas, and to improve the physical spaces in which such access is enjoyed; (b) Take measures to offer more and meaningful work opportunities and activities, conducive for both physical and mental health, to inmates in semi-open and closed establishments, and particularly those serving long or life sentences; (c) With regard to the currently very strict pretrial regime, take steps to ensure full observance of the presumption of innocence; this includes the right of persons in pretrial detention to enjoy as much social contact and opportunities for movement as is consistent with their status as innocent persons; (d) In that regard, should there be a need to separate co-defendants pending investigations, guarantee that this be done on a case-by-case basis and by court order; (e) Take measures to provide juveniles who break the law with alternatives to detention; and in cases where alternatives to detention are not available, guarantee that children are kept separate from adults at all times (see A/HRC/28/68); (f) Consider alternatives to prolonged or indefinite solitary confinement in “safe cells”, including supervision that does not exacerbate conditions that make detainees a risk to themselves or others; this includes training prison personnel to be able to identify and deal with early signs of potential mental illness; (g) In that regard, guarantee that adequate psychological treatment is readily available in cases where inmates have inflicted self-injury or show behaviour suggesting they may do so; (h) With regard to both solitary confinement and placement in “safe cells”, take measures to guarantee fair process, including by granting inmates the authority to challenge the decision and an independent review; (i) Ensure effective use of the in situ complaints scheme, including by providing ways in which inmates, including those in closed or high-security regimes, may enjoy confidential and anonymous access to sealed complaint boxes; (j) Consider revising the rules on and practices related to visits and other communications with the outside world: in the case of visits, this includes the type allowed (short or long, contact or non-contact), the categories of inmates allowed to enjoy visits, frequency of visits and the categories of visitors allowed to visit; with regard to communications, this includes the categories of inmates allowed to make telephone calls and the frequency with which they may be made; (k) Immediately eliminate all unjustified surveillance that risks constituting an invasion of the privacy of inmates; (l) Ensure regular and programmed medical check-ups, including routine analytical blood and urine medical tests and thorax radiology, by medical and lab staff, of all inmates and in all detention facilities; 20
