- 47 - 109. Conditions in the segregation unit at Malandrino Prison were satisfactory (well lit, including good access to natural light, and ventilated 9.3 m² cells, designed to accommodate one prisoner, each with direct access to a small exercise yard). 110. At Alicarnassos Prison, cells were also of a reasonable size for one person (7 m²); however, they were regularly used to accommodate two prisoners. Further, they had limited access to natural light and artificial lighting was very poor (from the adjacent corridor), they were unfurnished (save for mattresses placed directly on the floor), and they had an unscreened lavatory. Khania had two segregation cells, measuring respectively 2.8 m² and 5.4 m²; the former is too small to be used as prisoner accommodation and the latter should never accommodate more than one prisoner. The cells were very poorly lit and devoid of furniture (mattresses were placed directly on the floor) and sanitary facilities (prisoners were provided with chamber pots). The prison’s management stated that it avoided, to the extent possible, placing any prisoners in these cells. The segregation cells at Korydallos Prison for Men (in wing D) had been repainted; however, the CPT is disappointed to note that no other improvement had been made since its previous visits (cf. CPT/Inf (2001) 18, part I, paragraph 178 and part II, paragraph 57).22 In particular, the cells used for disciplinary segregation had still not been equipped with a table and chair. The CPT recommends that the situation in the segregation units in Alicarnassos, Khania and Korydallos prisons be reviewed, in the light of the above remarks. The 2.8 m² cell at Khania Prison should be withdrawn from service forthwith; further, as regards the 5.4 m² cell, arrangements should be made to ensure that any prisoner held in it is guaranteed ready access to a lavatory under decent conditions. 111. Prisoners held at Alicarnassos and Malandrino prisons were guaranteed outdoor exercise. However, the disciplinary unit at Khania did not have an outdoor exercise facility. Further, at Korydallos, only one small exercise yard was in service at the time of the visit; this facility was seldom used. Out-of-cell time and, in the case of prisoners undergoing administrative segregation, association time was spent in the corridor area. The CPT recommends that steps be taken to ensure that all prisoners held in the disciplinary units at Khania and Korydallos prisons are guaranteed at least one hour of outdoor exercise every day. 22 Cf. also, the judgement of the European Court of Human Rights in the case of Peers v. Greece.
