does not concern the provision according to which living space standard per an remand person in a detention facility shall not be less than 3 m2.114 The Public Defender is of the opinion that placement of remand/convicted persons in such conditions is in breach of the standards established by the European Committee for the Prevention of Torture (CPT). The CPT developed a strict standard for the minimum amount of living space that a prisoner should be afforded in a cell. According to this standard, 6m² of living space should be afforded for a single-occupancy cell. 4m² of living space should be afforded per prisoner in a multiple-occupancy cell. As the CPT has made clear in recent years, the minimum standard of living space should exclude the sanitary facilities within a cell. When devising the standard of 4m² of living space, the CPT had in mind, on the one hand, the trend observed in a number of western European countries of doubling up 8 to 9m² cells that were originally designed for single occupancy, and, on the other hand, the existence of large-capacity dormitories in prison establishments (colonies) in various central and eastern European countries. CPT has decided to promote a desirable standard. According to CPT, it would be desirable for a cell of 8 to 9m² to hold no more than one prisoner, regarding multipleoccupancy cells of up to four inmates by adding 4m² per additional inmate to the minimum living space of 6m² of living space for a single-occupancy cell.115 Therefore, the Public Defender of Georgia observes that the penitentiary establishments should afford the following standards: multiple occupancy cells for up to four inmates by adding 4m² per additional inmate to the minimum living space of 6m² for a single-occupancy cell. 3.5.3.
