- 35 79. The CPT has made it clear in its report on the 2009 visit that it is vitally important that the system of home leave be properly managed43. The prospect of home leave is a major incentive for good behaviour and remains an important factor in the maintenance of order within Greek prisons. However, the lack of social workers in each prison (in Domokos Prison there was no social worker for 600 prisoners) meant that it was not possible to fully analyse the family arrangements of each applicant nor properly evaluate their behaviour in prison. The CPT’s delegation also received complaints that prisoners were not properly informed about the criteria governing home leave. The CPT recommends that prisons be granted the necessary resources to ensure that applications for home leave are evaluated in a rigorous manner. 80. In most of the prisons visited there was limited resort to the use of segregation for disciplinary reasons, and the segregation units were primarily used to accommodate prisoners seeking protection from other prisoners. In Amfissa Prison, the segregation unit consisted of two minute cells (2.5m²), a corridor area of 3m² and a toilet. At the time of the visit, the unit was holding four prisoners for protection reasons, one of whom had been there for five months; in the recent past, the unit had held up to eight prisoners. The prisoners had to sleep on blankets placed on the floor. Further, these prisoners had no access to outdoor exercise, and spent 21 hours or more every day locked up in the unit. Such a state of affairs is totally unacceptable both as regards material conditions of detention and regime. As regards the former, the CPT must stress that cells of less than 6m² should be withdrawn from service. The CPT recommends that alternative facilities be found for prisoners on protection. In Domokos Prison, the segregation unit consisted of ten cells (each measuring approximately 10m²). At the time of the visit, the unit held four prisoners, three of whom were there for their own protection and one for administrative reasons. The inmates had no access outdoor exercise and were not offered any activities (including access to a television). The CPT recommends that every prisoner placed in segregation be guaranteed at least one hour of outdoor exercise every day. Further, for prisoners placed in segregation for nondisciplinary reasons, they should also be offered purposeful activities. 43 See CPT/Inf (2010) 33, paragraph 146.
