Administration of juvenile justice 73. The Committee welcomes the adoption of the Law on Juvenile Perpetrators of Criminal Acts and on Criminal Legal Protection of Minors, which provides for special provisions for young offenders, such as, inter alia, mandatory defence of minors, exemptions and limited duration of proceedings and the imposition of guidance measures instead of juvenile prison. The Committee also welcomes the various projects aimed at the reintegration of juvenile perpetrators. The Committee is concerned at the lack of implementation of the existing provisions due to various factual constraints and the lack of an effective juvenile justice system of specialized prosecutors, judges and social workers to deal with children in conflict with the law. 74. The Committee recommends that the State party: (a) Continue and strengthen its efforts to ensure the full implementation of juvenile justice standards, in particular articles 37, 40 and 39 of the Convention and other relevant international standards in this area, such as the United Nations Standard Minimum Rules for the Administration of Juvenile Justice (“the Beijing Rules”), the United Nations Guidelines for the Prevention of Juvenile Delinquency (“the Riyadh Guidelines”) and the United Nations Rules for the Protection of Juveniles Deprived of Their Liberty (“the Havana Rules”), taking into account the Committee’s general comment No. 10 (2007) on child rights in juvenile justice. (b) As a matter of priority, pay particular attention to: (i) The need to take measures to prevent and reduce the use of pretrial and other forms of detention and to make this detention as short as possible, inter alia, by developing and implementing alternatives to detention such as community service orders, interventions of restorative justice, etc.; (ii) The need to train police officers, prosecutors, judges, probation officers and others involved in the process of dealing with children in conflict with the law, in order to, inter alia, make sure that these children are interrogated by trained police officers who notify parents immediately about their child’s arrest and who encourage the presence of legal assistance for the child; (iii) The need to promote, in accordance with article 40, paragraph 1, of the Convention, social reintegration of children in the society; (c) Strengthen preventive measures, such as supporting the role of families and communities in order to help eliminate the social conditions leading to problems such as delinquency, crime; (d) Enhance enforcement of existing legislation;
