The United Nations Rules for the Protection of Juveniles Deprived of their Liberty known as the "Havana Rules" adopted by the United Nations General Assembly in 1990 are rules that determine the standards to be applied when a child is detained by a public judicial authority.

This text argues that deprivation of liberty must be a measure of last resort, which can only be ordered in exceptional cases. In this respect, this text sets out in detail the circumstances in which a child may be deprived of his or her liberty.In the event that deprivation of liberty appears to be unavoidable, these rules then determine very detailed instructions.
