“While the Strasbourg jurisprudence does not preclude reliance on articles other than article 3 as a ground for resisting extradition or expulsion, it makes it quite clear that successful reliance demands presentation of a very strong case. In relation to article 3, it is necessary to show strong grounds for believing that the person, if returned, faces a real risk of being subjected to torture or to inhuman or degrading treatment or punishment: Soering para 91; Cruz Varas para 69 Vilvarajah para 103.”
“136. In the light of the considerations set out above, the Court confirms the standard predominant in its case-law of 3 sq. m of floor surface per detainee in multi-occupancy accommodation as the relevant minimum standard underArticle 3 of the Convention . 137. When the personal space available to a detainee falls below 3 sq. m of floor surface in multi-occupancy accommodation in prisons, the lack of personal space is considered so severe that a strong presumption of a violation of Article 3 arises. The burden of proof is on the respondent Government which could, however, rebut that presumption by demonstrating that there were factors capable of adequately compensating for the scarce allocation of personal space (see paragraphs 126-128 above). 138. The strong presumption of a violation of Article 3 will normally be capable of being rebutted only if the following factors are cumulatively met: (1) the reductions in the required minimum personal space of 3 sq. m are short, occasional and minor (see paragraph 130 above): (2) such reductions are accompanied by sufficient freedom of 133 above); (3) the applicant is confined in what is, when viewed generally, an appropriate detention facility, and there are no other aggravating aspects of the conditions of his or her detention (see paragraph 134 above). 139. In cases where a prison cell – measuring in the range of 3 to 4 sq. m of personal space per inmate – is at issue the space factor remains a weighty factor in the Court’s assessment of the adequacy of conditions of detention. In such instances a violation of Article 3 will be found if the space factor is coupled with other aspects of inappropriate physical conditions of detention related to, in particular, access to outdoor exercise, natural light or air, availability of ventilation, adequacy of room temperature, the possibility of using the toilet in private, and compliance with basic sanitary and hygienic requirements (see paragraph 106 above). 140. The Court also stresses that in cases where a detainee disposed of more than 4 sq. m of personal space in multi-occupancy accommodation in prison and where therefore no issue with regard to the question of personal space arises, other aspects of physical conditions of detention referred to above (see paragraphs 48, 53, 55, 59 and 63-64 above) remain relevant for the Court’s assessment of adequacy of an applicant’s conditions of detention underArticle 3 of the Convention (see, for example, Story and Others v. Malta, nos. 56854/13, 57005/13 and 57043/13, §§ 112-113,29 October 2015 ). 141. Lastly, the Court would emphasise the importance of the CPT’s preventive role in monitoring conditions of detention and of the standards which it develops in that connection. The Court reiterates that when deciding cases concerning conditions of detention it remains attentive to those standards and to the Contracting States’ observance of them (see paragraph 113 above).”
“192. The serious shortage of prison staff in all establishments visited continues to be a major obstacle in ensuring the proper functioning of prisons. For example, at Diavata Prison staffing levels in relation to the number of prisoners have been reduced from 1:4 in 2007 to 1:40 in 2015 with only 15 officers on duty for 600 prisoners (see also section 2 above for numbers of prison officers on duty in other prisons). The CPT must repeat 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 leads to stronger groups of prisoners being able to exercise their powers unchecked over other inmates (see section 2 above). As was the case in 2013, the CPT’s delegation found that prison staff in many instances had to rely upon the leaders of those groups to maintain order in several of the prisons visited. Without sufficient staffing levels, it is also not possible to offer prisoners an acceptable regime thus reinforcing the warehousing phenomenon. Moreover, many prison staff complained about working up to 14 days consecutively without time off and about overtime and extra shifts not paid, and reported that they were seeking professional help due to the stress. Such a state of affairs not only increases the likelihood of burnout, but also undermines motivation. This in turn only increases the risks for both staff and prisoners. The current staffing levels in the Greek prison system must be radically increased starting with Korydallos Men’s prison. The CPT reiterates its recommendation to the Greek authorities that staffing levels in all prisons must be urgently reviewed and increased to levels which ensure effective control and a safe environment for prisoners and staff, as well as the possibility to put in place a programme of activities for all prisoners.”
