The Convention Against Torture and other Cruel, Inhuman or Degrading Treatment (CAT) (R) came into force in 1987. It defines torture and other illegal treatment and requires signatory states to prevent torture in any territories under their jurisdiction. This requirement entails not only banning torture in domestic law but also refraining from sending any persons to states where they are likely to experience torture. The CAT also requires that state official personnel, including law enforcement, be given training and guidance to prevent the use of torture. The CAT is monitored by the Committee Against Torture.
