- 27 The CPT calls upon the Greek authorities to take immediate steps to ensure that no more than one prisoner is accommodated in each of the nine 6m² cells in Special Area C at Korydallos Men’s Prison and that every prisoner has his own bed. Further, the cells should be properly refurbished and all prisoners in the Special Areas must be offered at least one hour of outdoor exercise every day and access to purposeful activities. The CPT would also like to be informed of the number of persons held in each of the Special Areas of Wings C, D, E and F on 1 June 2022. 46. At Nigrita Prison, the two cells near the reception area were used for the accommodation of vulnerable persons. At the time of the visit, one cell accommodated an older prisoner who was bedridden with a terminal illness and a second prisoner who had requested to be placed on protection after self-harming. This latter prisoner who was grappling with substance use took on the charge of caring for the older prisoner (feeding him and giving him water). In the adjacent cell was a foreign national from Iraq who spoke neither Greek nor English and was suffering from a long-standing bullet wound to his leg. The two cells were clearly not adapted for stays of more than a day or two as they were equipped only with a bed (no table or chairs) and had no access to hot water and no sockets for television or other appliances. They also had no access to any outdoor yard. In the circumstances, the placement of these prisoners in these two cells was appropriate, at least for a short period, and the prisoners themselves preferred to be located at the reception area rather than on the main wings. The CPT recommends that the two cells be appropriately furnished if they are to be used for stays of longer than 48 hours and that all persons accommodated in these cells be offered at least one hour of outdoor exercise every day. Further, if these cells are to be used for accommodating vulnerable persons, including prisoners with physical disabilities, they must be adapted and furnished accordingly. 4. Prison staff 47. The dire staffing situation in all the prisons visited was glaring and clearly undermined the functioning of the prison system. Regrettably, no progress has been made by the Greek authorities to remedy the totally inadequate staffing numbers in prisons since the CPT raised this issue explicitly in 2011 public statement on Greece in respect of prisons. The CPT has repeatedly stressed that an inadequate number of custodial staff renders prisons insecure for both prisoners and staff; in particular, it impedes any efforts to maintain effective control, which often leads to stronger groups of prisoners being able to exercise their powers unchecked over other inmates. The delegation observed in the prisons visited how the inmate population was separated along ethnic/cultural lines and that within each of these specific groups there was a defined hierarchical structure, which all inmates adhering to that group were obliged to follow. It was also evident that prison staff in many instances relied upon the leaders of these groups to maintain order in an establishment. Furthermore, low staffing levels make it nearly impossible to provide an acceptable regime for prisoners.
