- 47 The delegation did not find any evidence of excessive recourse to disciplinary sanctions, and more particularly to the sanction of confinement in a special cell. As regards Larissa Prison, a prison officer acknowledged that in the past, a quite liberal use had been made of the sanction of confinement in a special cell; however, in recent times, that sanction had been employed with greater circumspection. This was borne out by the register of disciplinary sanctions. 132. Confinement in a special cell is also one of the measures to which a prison director might have recourse "for the maintenance of order and for purposes of protection and pacification in penal institutions" (cf. Rule 93.1 (ii) of the Code). No time limit is specified4. The CPT would like to be informed of the safeguards which apply when such a measure is taken against the wishes of the prisoner concerned (right to be informed of the reasons for the measure; right to be heard; review procedures; right of appeal to a higher authority; etc.). 133. The segregation unit at Korydallos Mens Prison consisted of two groups of 10 cells, all of which were apparently used for both disciplinary confinement and other segregation purposes. The cells measured approximately 7 m²; they were equipped with a bed, but no other furniture (eg. table or chair). There was adequate ventilation and artificial lighting; however, access to natural light was, at best, mediocre. Each cell possessed an asian toilet, and some cells had a wash basin. The adjacent exercise yards measured approximately 40 m². The whole unit required to be - and was being - redecorated. 134. No-one was being confined as a punishment at the time of the delegation's visit. A number of transvestite prisoners had been held in the unit for several months at their own request. Other prisoners were being held in the unit involuntarily, presumably under Rule 93 or 94 of the Code (the absence of a segregation unit register made it difficult to ascertain the precise grounds); certain of them appeared to have psychological or psychiatric problems. The prisoners were allowed to move freely within the unit and exercise areas during much of the day, and they had TV sets and other personal possessions in their cells (though staff indicated that a prisoner undergoing disciplinary confinement would remain in his cell and would not be allowed personal possessions). 135. The conditions of detention in this segregation unit are on the whole acceptable for prisoners undergoing the disciplinary sanction of confinement in a special cell. However, the CPT considers that it would be desirable for the cells accommodating such prisoners to be fitted with a table and chair, if necessary fixed to the floor. The CPT also recommends that all prisoners, including those confined to a special cell as a punishment, be allowed at least one hour of exercise in the open air everyday. 4 The director may also order that prisoners suffering from an infectious disease or who are a danger to themselves or others be confined in a special cell (Rule 94). Such a measure is to be lifted as soon as the reason which caused its imposition disappears; if that reason persists, the prisoner concerned is to be transferred to a specialist state hospital for treatment.
