III. Content of the obligation to take effective measures to prevent torture 8. States parties must make the offence of torture punishable as an offence under its criminal law, in accordance, at a minimum, with the elements of torture as defined in article 1 of the Convention, and the requirements of article 4. 9. Serious discrepancies between the Convention’s definition and that incorporated into domestic law create actual or potential loopholes for impunity. In some cases, although similar language may be used, its meaning may be qualified by domestic law or by judicial interpretation and thus the Committee calls upon each State party to ensure that all parts of its Government adhere to the definition set forth in the Convention for the purpose of defining the obligations of the State. At the same time, the Committee recognizes that broader domestic definitions also advance the object and purpose of this Convention so long as they contain and are applied in accordance with the standards of the Convention, at a minimum. In particular, the Committee emphasizes that elements of intent and purpose in article 1 do not involve a subjective inquiry into the motivations of the perpetrators, but rather must be objective determinations under the circumstances. It is essential to investigate and establish the responsibility of persons in the chain of command as well as that of the direct perpetrator(s). 10. The Committee recognizes that most States parties identify or define certain conduct as ill-treatment in their criminal codes. In comparison to torture, ill-treatment may differ in the severity of pain and suffering and does not require proof of impermissible purposes. The Committee emphasizes that it would be a violation of the Convention to prosecute conduct solely as ill-treatment where the elements of torture are also present. 11. By defining the offence of torture as distinct from common assault or other crimes, the Committee considers that States parties will directly advance the Convention’s overarching aim of preventing torture and ill-treatment. Naming and defining this crime will promote the Convention’s aim, inter alia, by alerting everyone, including perpetrators, victims, and the public, to the special gravity of the crime of torture. Codifying this crime will also (a) emphasize the need for appropriate punishment that takes into account the gravity of the offence, (b) strengthen the deterrent effect of the prohibition itself, (c) enhance the ability of responsible officials to track the specific crime of torture and (d) enable and empower the public to monitor and, when required, to challenge State action as well as State inaction that violates the Convention.
