The reservations related to the practice of granting consent for visits only to parents, which is an excessive restriction, unsupported by the legislation. Moreover, at JDC in Laskowiec the person authorized to determine contacts of the juvenile with the open environment is the housemaster, which, in the NMP's opinion, is a too far-reaching authorization. On the other hand, the rules of procedure do not specify the rights to contacts with the family of the juveniles placed in the transition room. The violation of the right of the juveniles discussed in this paragraph is also the practice of controlling all the letters of the juveniles whose application was confirmed during the visits in the establishment in Falenica, Laskowiec, Białystok and Mrozy. It should be stressed that it is completely unacceptable to control correspondence of the juveniles addressed to the institutions such as the Ombudsman for Children or Human Rights Defender, which was found in JDC in Mrozy. The practice threatening the protection of family ties was also the practice observed by the National Preventive Mechanism representatives in the Juvenile Detention Centre in Białystok – a juvenile from one of the groups, the so-called readaptation group, had limited contact by telephone with his parents. During the day, the juvenile had the right to make only one phone call the duration of which could not exceed 5 minutes. The NMP recommendations to remove the above-mentioned irregularities have been implemented in accordance with the explanations of the directors of the detention centres in Laskowiec, Mrozy and Falenica. The director of JDC in Białystok negated the National Preventive Mechanism recommendations. He informed that the provisions of the Act on Juvenile Delinquency Proceedings on the implementation of the visits and control of correspondence were observed and that he had no plans to introduce any changes in that regard. f) Right to medical care United Nations General Assembly Resolutions no. 43/173 of 9 December 1988.
