A/HRC/4/40/Add.4 page 3 On the basis of its findings, the Working Group makes recommendations to the Government aimed at strengthening the control over the legality of detention at all stages of the criminal justice process. The Working Group calls upon the Government to urgently address the situation of detainees held under the old Criminal Procedure Code. It also recommends the establishment of a specific, professionally staffed penitentiary system separate from the police. Finally, the Working Group stresses the importance of strengthening prevention, law enforcement and criminal justice in dealing with the maras specifically, and with crime in general, instead of relaxing the rule of law and the protection against arbitrary detention.
