- 56 c. segregation 128. The delegation was concerned to discover that prisoners can be placed in the segregation units without such confinement being registered (i.e. for so-called cooling down periods), as recording only occurs once there is a decision by the Disciplinary Council authorising segregation; for example, the delegation met persons in Korydallos Men’s Prison who had been placed in the segregation unit for several days, but whose stays were not recorded. It also lends credence to claims from prisoners in several prisons that they were arbitrarily placed in the segregation unit when returning from leave, court or hospital. The CPT recommends that the Greek authorities ensure that all placements in a prison segregation unit are in accordance with the provisions of the Prison Law, properly authorised and correctly recorded in the relevant register. 129. As to the conditions in the segregation units visited, in Chios Judicial Prison the single isolation cell (8.5m²) had minimal access to natural light and poor artificial lighting and ventilation. The only furnishing in the cell was a decrepit mattress. The adjoining toilet area, separated by a barred gate, was dirty and the flush did not function; there was also no wash basin. In Komotini Judicial Prison, the five isolation cells were also not in a fit condition to hold prisoners. The delegation met a prisoner who had already spent seven days of his ten-day punishment in one of these cells; it was hot and filthy, with a putrid smell; there was poor ventilation, no bed (only a dirty mattress on the ground), no wash basin (hands were washed in the toilet) and minimal access to natural light. The CPT recommends that the segregation cells in these prisons be urgently renovated in the light of the above remarks. In addition to access to natural light, adequate artificial lighting and ventilation, they should also be equipped with a bed and suitable seating; preferably, a table should be installed as well. 130. The delegation was surprised to observe that there had been no improvements to the disciplinary cells in Korydallos Men’s Prison since the previous visit. In its response to the 2001 visit report (cf. CPT/Inf (2002) 32, paragraph 110), the Greek authorities stated that the cells were deliberately not equipped in order to prevent self-destructive tendencies and suicides. As already recommended by the CPT, the first concern can be addressed by installing a table and chair that are fixed to the floor. As to prisoners who are identified as being at risk of suicide or self-harm, they should be accommodated in specially adapted cells and placed under close-supervision – the cells in the segregation unit are totally inappropriate for such purposes. Further, in the course of the 2005 visit the delegation observed that some of the 6m² cells were being used to accommodate two prisoners; certain prisoners had to share a bed with others; and neither the toilets nor the shower were in working order. In addition, many complaints were heard that outdoor exercise was not offered on a daily basis. The CPT recommends that the material conditions in the segregation unit be substantially improved in the light of the above remarks, and that all prisoners undergoing disciplinary punishment are offered at least one hour of outdoor exercise per day.
