Juveniles should only be deprived of their liberty in accordance with the principles and procedures set forth in these Rules and in the United Nations Standard Minimum Rules for the Administration of Juvenile Justice (The Beijing Rules). Deprivation of the liberty of a juvenile should be a disposition of last resort and for the minimum necessary period and should be limited to exceptional cases. The length of the sanction should be determined by the judicial authority, without precluding the possibility of his or her early release.
