The United Nations Convention Against Torture and Other Cruel, Inhuman, or Degrading Treatment or Punishment (CAT) requires signatory parties to take measures to end torture within their territorial jurisdiction. For purposes of the Convention, torture is defined as an extreme form of cruel and unusual punishment committed under the color of law. The Convention allows for no circumstances or emergencies where torture could be permitted. Additionally, CAT Article 3 requires that no state party expel, return, or extradite a person to another country where there are substantial grounds to believe he would be subjected to torture.
