Version as at 1 July 2023 Crimes of Torture Act 1989 Schedule 1 Parties undertake to include such offences as extraditable offences in every extradition treaty to be concluded between them. 2. If a State Party which makes extradition conditional on the existence of a treaty receives a request for extradition from another State Party with which it has no extradition treaty, it may consider this Convention as the legal basis for extradition in respect of such offences. Extradition shall be subject to the other conditions provided by the law of the requested State. 3. States Parties which do not make extradition conditional on the existence of a treaty shall recognize such offences as extraditable offences between them‐ selves subject to the conditions provided by the law of the requested State. 4. Such offences shall be treated, for the purpose of extradition between States Parties, as if they had been committed not only in the place in which they occurred but also in the territories of the States required to establish their jurisdiction in accordance with article 5, paragraph 1. Article 9 1. States Parties shall afford one another the greatest measure of assistance in connection with criminal proceedings brought in respect of any of the offences referred to in article 4, including the supply of all evidence at their disposal necessary for the proceedings. 2. States Parties shall carry out their obligations under paragraph 1 of this article in conformity with any treaties on mutual judicial assistance that may exist between them. Article 10 1.

Each State Party shall include this prohibition in the rules or instructions issued in regard to the duties and functions of any such person.
