A/HRC/31/57/Add.3 86. Infractions of prison rules are punishable by the withdrawal of privileges. In the case of serious infractions, punishment may entail confinement in an isolation cell. The official maximum time in isolation for disciplinary breaches was recently reduced from 20 to 14 days; the Special Rapporteur notes that, in practice, the number of days in isolation is frequently reduced. In addition, during isolation, inmates continue to be allowed an hour outside in a small exercise yard, by themselves. 87. The Special Rapporteur learned, however, that some inmates are held permanently in isolation regime, spending 23 hours a day alone in their cells, some of them for years. He notes the security reasons given by the prison authorities. While the Special Rapporteur finds that such a regime might be justified in cases where an inmate so requests or in cases of risk of self-injury, he noted with concern that at least one inmate had spent two and a half years in isolation without being offered any alternative regime. 88. The Special Rapporteur notes with concern that while inmates are notified whenever a sanction (including solitary confinement) is imposed, no actual process of hearing is made available to challenge the decision, or of shared decision-making through a disciplinary board. 89. In addition, the Special Rapporteur received testimonies of inmates who had had their sentences extended, generally when they were close to their date of release. He heard allegations that the authorities would claim to have found blades or other weapons in their possession, which according to the inmates were planted there by the authorities themselves. The inmates were subsequently referred to the Office of the Chief Prosecutor with new charges, resulting in a new conviction. In another case, an inmate originally charged with homicide complained to the Public Defender about alleged ill-treatment in October 2014, and was subsequently charged with having made a false complaint. The Special Rapporteur stresses that criminal charges of false testimony risk having a chilling effect on future complaints, whether to the national preventive mechanism or to any other authority. 90. While the Special Rapporteur is not in a position to verify the above allegations, he notes with concern that some inmates have been re-charged and re-sentenced, therefore made to serve a term much longer than the one originally handed down. He also notes that convicted persons have a right to expect an end to their prison terms, and to rehabilitation and reintegration into society. 5. Medical attention 91. With regard to medical attention and the documentation of physical or psychological trauma, the Special Rapporteur learned that a medical examination is routinely conducted on detainees upon their admission to or transfer between prison facilities, and medical registration forms are filled out. He found that all prison facilities are adequately staffed, with doctors and nurses working in shifts, to serve the population with basic services, including dental care. Similarly, in temporary detention isolators, medical exams are conducted upon the detainee’s arrival, as are services through the public hospital and ambulance services when considered necessary. The Special Rapporteur nonetheless noted an overall need for improvement in quality and consistency of recording and documentation and of the medical attention offered. 92. With regard to the recording and documentation of injuries, the Special Rapporteur found that reports were generally incomplete, lacking correct and complete descriptions or photographic documentation of the injury, and an interpretation of the probable cause. While the Special Rapporteur noted with concern that in only one establishment did the head doctor have a copy of the Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (the Istanbul 15
