"Deprivation of liberty" has been known as one of the traditional executive guarantees of criminal law, used in the form of punishment for convicts. However, today with certain social norms and necessities, we are witnessing the use of "deprivation of liberty" in other branches in the form of official, educational, hygienic, disciplinary, and similar guarantees. The increasing importance and the extending use of this type of non-criminal "deprivation of liberty" in recent years, has caused the laws of various countries and international documents to recognize this type of "deprivation of liberty". Among these documents is the European Convention on Human Rights, which. as an advancing legal document in the international realm, in its 5th article, has considered an independent nature of criminal "deprivation of liberty", by numerating the instances of non-criminal "deprivation of liberty", while accepting the notion of non-criminal "deprivation of liberty".
