- 36 95. In the following paragraphs, the CPT shall make a number of specific recommendations concerning the prison establishments visited by its delegation. However, it wishes to emphasise at the outset that the act of depriving someone of his liberty brings with it the responsibility for the State to detain him under conditions which respect the inherent dignity of the human person. The facts found during the course of the CPT's visit demonstrate that as a consequence of the present level of overcrowding in prisons, the Greek authorities are not in a position to fulfil that responsibility vis-à-vis many prisoners. The CPT therefore recommends that a very high priority be given to measures to reduce overcrowding in the Greek prison system. 96. In addition to measures to combat overcrowding, steps to reinforce the existing prison staff resources are also required. At the time of the delegation's visit, some 25% of the 2250 posts making up the official staff complement were vacant; and this latter figure had been calculated on the basis of a prison population of 4500, not 6700. The CPT's delegation saw for itself that the ratio of staff to prisoners could on occasion be alarmingly low (cf. for example, paragraph 107). It should be emphasised that an inadequate staff/prisoner ratio not only renders the provision of an acceptable regime well-nigh impossible, but also generates an insecure environment for both staff and prisoners. The CPT recommends that appropriate steps be taken to fill all vacant prison staff posts. It also recommends that the existing official staff complement be reviewed, in order to ascertain whether it is adequate in the light of current and envisaged prison population levels. 2. Torture and other forms of ill-treatment 97. The CPT's delegation found no evidence of torture in the prison establishments it visited and heard no allegations of such acts in other prisons in the country. The two persons held in the Pavlos Melas Military Prison had no complaints whatsoever about the way they were treated there. As regards the civil prison establishments visited, a distinction must be made between the Korydallos Prison Complex and Larissa Prison. 98. The delegation heard hardly any allegations of physical ill-treatment by staff at the Korydallos Prison Complex. It noted that, overall, day to day dealings between staff and prisoners were relatively courteous and relaxed; and this despite often very poor material conditions of detention, which did not facilitate the maintenance of good relations. The above also applies on the whole to the Psychiatric Unit at Korydallos, although it must be added that existing arrangements in the Unit for dealing with mentally disturbed and violent prisoners involve a clear risk of physical ill-treatment (cf. paragraph 188).
