The multilateral treaty against torture (Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment or “CAT”) has been examined.
CAT also has a supplement (the Optional Protocol to the Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment). It created the Subcommittee on the Prevention of Torture with a mandate to visit places where persons are deprived of liberty in the States Parties. This Protocol also requires States parties to establish an independent national mechanism for the prevention of torture at the domestic level with a similar mandate to inspect places of detention. The Protocol’s purpose, as set forth in its Article 1, is to establish “a system of regular visits undertaken by independent international and national bodies to places where people are deprived of their liberty, in order to prevent torture and other cruel, inhuman or degrading treatment or punishment.”
The Protocol was adopted by the U.N. General Assembly on December 18, 2002, and it entered into force on June 22, 2006.
