CRC/C/GTM/CO/3-4 97. The Committee recommends that the State party establish a 3-4 digit, toll-free, 24-hour national helpline for children. The State party should collaborate with NGOs willing to work towards establishing a helpline, ensure that all children are aware of and can access the helpline, and that it has an outreach component for the most marginalized children, and allocate funds to provide services in remote areas. Administration of juvenile justice 98. While welcoming the fact that the PINA Law establishes special courts for children in conflict with the law, the Committee is concerned at: (a) The insufficient number of specialized judges, as well as of judges charged with the control of execution of sanctions, and the existence of only one juvenile appellate court. (b) The lack of sufficient information on the availability of alternative measures to deprivation of liberty; (c) The large number of adolescents in detention centres and information received to the effect that offences against property are the main reason for detention; (d) The centralization of detention centres in the capital city and surrounding areas, making children’s contact with their families and communities difficult; (e) The serious overcrowding and the lack of care and reintegration programmes in the detention centres; (f) The insufficient and undertrained staff in detention centres; and (g) The absence of internal and external controls on the detention centres. 99. The Committee urges the State party to ensure that juvenile justice standards are fully implemented, in particular articles 37 (b), 40 and 39 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 its general comment No. 10 (2007) on children’s rights in juvenile justice (CRC/C/GC/10). It further recommends that the State party: (a) Take all necessary measures, including a preventive approach to addressing juvenile criminality, in particular paying adequate attention to social factors and strengthening various forms of restorative justice (probation, counselling, community service or suspended sentences) to ensure that children are held in detention only as a last resort and for the shortest period of time; (b) Take all necessary measures to ensure that all cases of detention are in compliance with the law and respect the rights of the child as set out under the Convention. The State party should ensure that children are held separately from adults both in pre-trial detention and after being sentenced; (c) Take all necessary measures to ensure that conditions in detention facilities are not detrimental to a child’s development and meet international minimum standards, including regular contact with their families, eliminating overcrowding and providing sufficient well-trained staff in detention centres; 17
