CRC/C/PRY/CO/3 (d) Carry out efforts in order to promote and ensure a better coordination among the different institutions involved; and (e) received. Establish an effective system for monitoring and follow-up of the calls Administration of juvenile justice 76. The Committee welcomes the efforts carried out by the State party to improve the system of juvenile justice, such as Act No. 1680/2001, which establishes a system of specialized justice for the treatment of issues concerning children in conflict with the law. However, it is concerned at the lack of information provided by the State party on the professionals of the justice system, such as judges and public defenders, specializing in children and at the wide use of preventive detention for children between 16 and 18 years of age, as well as the precarious conditions in which adolescents serve sentences. Furthermore, the Committee is concerned at the lack of an effective policy to implement socio-educational measures directed towards children in conflict with the law. 77. The Committee urges the State party to ensure that juvenile justice standards are fully implemented, in particular articles 37 (b), 39 and 40 of the Convention, as well 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). In particular, the Committee urges the State party to take into account the Committee’s general comment No. 10 (2007) on children’s rights in juvenile justice. It also recommends that the State party: (a) Undertake efforts to implement the policy on juvenile justice; (b) Introduce specialized judges for children in all the regions and ensure such specialized judges receive appropriate education and training; (c) Ensure that all stakeholders involved with the system of juvenile justice are trained to effectively implement justice, including police officers and prosecutors; (d) Develop alternatives to the deprivation of liberty, such as probation, mediation, community services orders, or suspended sentences, wherever possible; (e) Ensure that the deprivation of liberty is used only as a measure of last resort and for the shortest appropriate period of time, and is reviewed on a regular basis and that children are separated from adults during such deprivation; (f) Seek technical assistance and other cooperation from the Interagency Panel on Juvenile Justice, which includes the United Nations Office on Drugs and Crime, the Office of the High Commissioner for Human Rights, UNICEF and NGOs. Protection of witnesses and victims of crimes 78. The Committee also recommends that the State party ensure, through adequate legal provisions, procedures, and regulations, that all children victims and or witnesses of crimes, e.g. children victims of abuse, domestic violence, sexual and economic exploitation, abduction, and trafficking and witnesses of such crimes, have effective access to justice and be provided with the protection required by the Convention and that it take fully into account the United Nations Guidelines on Justice in Matters involving Child Victims and Witnesses of Crime. 18
