to promote “desirable” standards regarding multiple-occupancy cells of up to four inmates by adding 4m² per addition­al inmate to the minimum living space of 6m² of living space for a singleoccupancy cell: ►► 2 prisoners: at least 10m² (6m² + 4m²) of living space + sanitary annexe; ►► 3 prisoners: at least 14m² (6m² + 8m²) of living space + sanitary annexe; ►► 4 prisoners: at least 18 m² (6m² + 12m²) of living space + sanitary annexe. In other words, it would be desirable for a cell of 8 to 9m² to hold no more than one prisoner, and a cell of 12m² no more than two prisoners. 86. The CPT expects that the abovementioned minimum living space stand­ ards will be systematically applied in General Report of the CPT, 2015 ► Page 44 all prison establishments in Council of Europe member states, and hopes that more and more countries will strive to meet the CPT’s “desirable” standards for multiple-occupancy cells, in particular when constructing new prisons. 87. The CPT seeks to provide guidelines to practitioners and other interested parties, by clearly stating the CPT’s minimum standards regarding living space for prisoner(s) in a given cell. Ultimately, it is for the courts to decide whether a particular person has experienced suffering that has reached the threshold of inhuman or degrading treatment within the meaning of Article 3 of the ECHR, taking into account all kinds of factors, including the individual’s personal constitution. The number of square metres available per person is but one factor, albeit often a very significant or even decisive one.
