should not happen. The staff of this kind of establishments should behave in suach a way so as to avoid conflicts and eliminate bad examples from the environments, they were raised in. In response to the recommandations of the National Preventive Mechanism, the heads of the mentioned establishments informed the Human Rights Defender that the collective responsibility shall not be used. Moreover, the catallogue of disciplinary measures of some establishments, have been extended by cleaning of the establishment (e.g. YCC No 1, YCC No3 and YSC No 2 in Łódź) or physical exercises. In the opinion of the Mechanism representatives, this kind of punishments may cause a distortion of image of work as a form of self-maintainance and physical exercise as a form of getting fit. For that reason, such provisions were erased from internal regulations. In response, the head of the Youth Sociotherapy Centre in Łódź informed that during their meeting the juveniles decided there is no need to erase the punishment consisting in working for the establishment from the punishment regulation. In relation to that Mechanism presented its position on the matter once again and, in consequence, this punishment was removed from the punishment regulation. It was erased from regulation also in other etablishemnts, where it was recommanded by the Human Rights Defender. When it comes to the recommendations concerning non-statutory punishments, the head of the Silesian Care Centre in Różanystok explained that daily reports and class register are constatly controlled in order to check if the punishments in use are in compliance with the punishment and awards regulation. The head tried also to examine the issue of inhuman punishment, reported to the visiting persons. In his opinion, it is impropable that an inmate was punished with „kneeling all night by a wall”, as such a punishment could be perceived by supervisors and could be communicated to other persons, including school staff. The head stated that the are no grounds to believe that kneeling all night was used as a punishment. The same situation concerned cleaning of toilet ceiling, which is impossible to verify without detailed information. Despite explanations presented by the head of the establishment, in the opinion of the Mechanism representatives, the number of signals they got during interview with inmates of SCC in Różanystok means it is possible that this kind of punishment might have been used. The head of YCC in Podzamcze promised to focus in particular on the way the juveniles are treated by their tutors. c) Coercive means in use Recommendation of the Committee of Ministers CM/Rec(2008)11 on the European Rules for juvenile offenders subject to sanctions or measures.
