"Juvenile delinquency is certainly one of the best illustrations of the difficulties encountered by contemporary legislators in adapting criminal law to persons whose discernment is non-existent or incomplete". This assertion reflects the finesse of the issue of implementing the criminal responsibility of minors whose discernment is, depending on the case, non-existent or incomplete. Repressive juvenile justice has its own unique hallmark, the right balance between the need for repression and the imperative of protection: a veritable panache. Most of the protective and guiding principles relating to children's rights are dictated by the CRC.A true institutional mimicry, these protective principles have established a real foundation of juvenile law in our domestic legislation. This is how juvenile courts came into being in Niger, following a singular process. At least one juvenile court judge has been set up in each of Niger's ten regional courts, with a view to safeguarding and guaranteeing the application of the delicate and repressive juvenile justice system.
