In 1949, the Universal Declaration of Human Rights (UDHR) was adopted by the United Nations General Assembly. Although the Declaration is non-binding, the basic human rights outlined within it have served as the foundation of customary international law.[1] The relevance of the Declaration to solitary confinement is found in Article 5, which states that “No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment."[88] Thus, if solitary confinement is believed to constitute torture or cruel, inhuman, or degrading treatment or punishment, then the country practicing solitary confinement is violating the provisions set by the UDHR.
