CAT/C/GC/2 page 5 that States or individuals can incur for perpetrating torture and ill-treatment under international customary law and other treaties. 16. Article 2, paragraph 1, requires that each State party shall take effective measures to prevent acts of torture not only in its sovereign territory but also “in any territory under its jurisdiction.” The Committee has recognized that “any territory” includes all areas where the State party exercises, directly or indirectly, in whole or in part, de jure or de facto effective control, in accordance with international law. The reference to “any territory” in article 2, like that in articles 5, 11, 12, 13 and 16, refers to prohibited acts committed not only on board a ship or aircraft registered by a State party, but also during military occupation or peacekeeping operations and in such places as embassies, military bases, detention facilities, or other areas over which a State exercises factual or effective control. The Committee notes that this interpretation reinforces article 5, paragraph 1 (b), which requires that a State party must take measures to exercise jurisdiction “when the alleged offender is a national of the State.” The Committee considers that the scope of “territory” under article 2 must also include situations where a State party exercises, directly or indirectly, de facto or de jure control over persons in detention. 17. The Committee observes that States parties are obligated to adopt effective measures to prevent public authorities and other persons acting in an official capacity from directly committing, instigating, inciting, encouraging, acquiescing in or otherwise participating or being complicit in acts of torture as defined in the Convention. Thus, States parties should adopt effective measures to prevent such authorities or others acting in an official capacity or under colour of law, from consenting to or acquiescing in any acts of torture. The Committee has concluded that States parties are in violation of the Convention when they fail to fulfil these obligations. For example, where detention centres are privately owned or run, the Committee considers that personnel are acting in an official capacity on account of their responsibility for carrying out the State function without derogation of the obligation of State officials to monitor and take all effective measures to prevent torture and ill-treatment. 18. The Committee has made clear that where State authorities or others acting in official capacity or under colour of law, know or have reasonable grounds to believe that acts of torture or ill-treatment are being committed by non-State officials or private actors and they fail to exercise due diligence to prevent, investigate, prosecute and punish such non-State officials or private actors consistently with the Convention, the State bears responsibility and its officials should be considered as authors, complicit or otherwise responsible under the Convention for consenting to or acquiescing in such impermissible acts. Since the failure of the State to exercise due diligence to intervene to stop, sanction and provide remedies to victims of torture facilitates and enables non-State actors to commit acts impermissible under the Convention with impunity, the State’s indifference or inaction provides a form of encouragement and/or de facto permission. The Committee has applied this principle to States parties’ failure to prevent and protect victims from gender-based violence, such as rape, domestic violence, female genital mutilation, and trafficking. 19. Additionally, if a person is to be transferred or sent to the custody or control of an individual or institution known to have engaged in torture or ill-treatment, or has not implemented adequate safeguards, the State is responsible, and its officials subject to punishment for ordering, permitting
