previous visit, had not been removed. What is more, after analysing the documentation and interviewing the juveniles and the director of the establishment it was determined that the juveniles in the Detention Centre were subject to degrading treatment and punishment. Most reservations were reported as regards placing the juveniles in transition rooms – without any legal basis, for a long period of time, under inappropriate living conditions. The director of the Detention Centre and the head of the District Educational Supervision Team in Białystok mostly did not share the post-visit findings and recommendations and introduction of some changes suggested by the NMP representatives encountered difficulties. In the connection with the above, the Human Rights Defender applied to the Ministry of Justice for addressing the disputable – in the opinion of the director of JDC in Białystok - issues. The report on the actions carried out in the Juvenile Detention Centre in Białystok, submitted to the Ministry of Justice, became a basis for initiating the explanatory proceedings at the Department of Decision Implementation and Probation of the Ministry of Justice, during which the director of the Detention Centre and the head of the District Educational Supervision Team in Białystok were asked for explanations. Also, the Chief Judge of the District Court in Białystok supervising the establishment was obliged to submit an opinion on the way of the implementation of the tasks by the Detention Centre. The Chief Judge of the District Court in Białystok issued a favourable opinion on the work of the director of the establishment, confirming the validity of four charges only, with the information about their immediate removal. In addition, within the framework of his powers, he obliged himself to order a comprehensive visit to the Juvenile Detention Centre in Białystok. Once the Department of Decision Implementation and Probation received the information in the course of the explanatory proceedings, it was decided to inspect the establishment, in order to assess the state of the implementation of recommendations issued by the National Preventive Mechanism as a result of the visit to the Detention Centre carried out in 2008 and to compare the results with the evaluation made during reinspection in 2010. Based on the inspection results, it was found that a number of charges specified in the post-visit information of the NMP representatives on the irregularities in the functioning of the establishment had been confirmed. Therefore, the director of the establishment was obliged to remove the irregularities found. a) Living conditions Recommendations CM/Rec(2008)11 of the Committee of Ministers to the Member States on the European Rules for juvenile offenders subject to sanctions or measures.
