CAT/OP/KAZ/1/Add.1 244. All convicted prisoners, irrespective of their length of sentence, have equal access to everyday products (food, clothes and other essential items) and to recreational opportunities (reading newspapers and magazines and watching television). 245. No differentiation is made on these issues. 246. The conditions of detention are the only variable; they depend on the regime under which a sentence is being served (ordinary, relaxed or strict). 247. In accordance with article 127 of the Penalties Enforcement Code, it has been made possible for prisoners serving life sentences and those in prison hospitals to receive primary, basic secondary and general secondary education. 248. It has been made possible for prisoners serving life sentences and those in prison hospitals to receive primary, basic secondary and general secondary education. 249. Convicted prisoners are encouraged to take primary, basic secondary and general secondary education, and their willingness to do so is taken into account in appraising their behaviour and preparing a character assessment. 250. Under article 141 of the Penalties Enforcement Code, prisoners serving life sentences are entitled to a daily walk lasting: (1) One hour for those held under the strict regime (2) One and a half hours for those held under the ordinary regime (3) Two hours for those held under the relaxed regime Paragraph 122 In that spirit, the Subcommittee recommends discontinuing the overemphasis on security and, in particular, the degrading procedure followed when taking prisoners serving life sentences out of their cells, and putting an end to the excessive use of systematic security measures. 251. Rule 11 of the Nelson Mandela Rules stipulates that different categories of prisoners shall be kept in separate institutions or parts of institutions, taking account of their sex, age, criminal record, the legal reason for their detention and the necessities of their treatment. 252. Rule 37 of the Nelson Mandela rules refers to any form of involuntary separation from the general prison population, such as solitary confinement, isolation, segregation, special care units or restricted housing, whether as a disciplinary sanction or for the maintenance of order and security, including promulgating policies and procedures governing the use and review of, admission to and release from any form of involuntary separation. 253. National laws and regulations provide for special treatment for prisoners serving life sentences. 254. Moreover, rule 89 of the Nelson Mandela Rules stipulates that the fulfilment of these principles requires individualization of treatment and for this purpose a flexible system of classifying prisoners in groups. It is therefore desirable that such groups should be distributed in separate prisons suitable for the treatment of each group. 255. According to rule 93 of the Nelson Mandela Rules, the purposes of classification are: (a) To separate from others those prisoners who, by reason of their criminal records or characters, are likely to exercise a bad influence (b) To divide the prisoners into classes in order to facilitate their treatment with a view to their social rehabilitation 256. So far as possible, separate prisons or separate sections of a prison shall be used for the treatment of different classes of prisoners. 257. In addition, preliminary observation 2 of the Nelson Mandela Rules stipulates that, in view of the great variety of legal, social, economic and geographical conditions of the world, it is evident that not all of the rules are capable of application in all places and at all times. They should, however, serve to stimulate a constant endeavour to overcome practical 28 GE.18-05420
