Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
In 2009, in its combined third and fourth periodic reports to the Committee against Torture, Sri Lanka stated:
33. Article 3 of [the 1984] Convention against Torture prohibits … extradition of a person where there are substantial grounds for believing that such person faces the threat of torture in the receiving State. Sri Lanka as a policy does not extradite persons where such threats exist and there have been no instances of persons in Sri Lanka seeking to refute an extradition order based on allegations of torture.
34. Additionally, no allegations have been levelled against the State for any action in breach of this principle. Any such concerns will be dealt with at the Executive level.
35. The Extradition Law No. 8 of 1977 of Sri Lanka incorporates restrictions on extradition which includes the possibility of punishment, detention or restriction by reasons of race, nationality or political opinion. This provision covers the situations envisaged by Section 3 of  CAT [Convention against Torture]. Further there are adequate provisions under the laws governing Immigration and Emigration, and Extradition to honour this principle.
38. Article 7 of the  Convention against Torture states that if the authorities should decide not to extradite the accused then it should submit the case to its competent authorities for the purpose of prosecution. This provision is reflected in sections 7, 8, and 9 of the CAT Act [Convention against Torture Act(1994)].

Sri Lanka further stated:
47. … Sri Lanka has also undertaken to inform any other State having jurisdiction of the offence, or any other State that requests the extradition of the accused, the measures that have been or will be taken to extradite or prosecute such person for that offence.
50. In accordance with Sections 8 of the CAT Act [Convention against Torture Act (1994)], Sri Lanka has amended its extradition law to provide for torture as an extraditable offence. Although as per the Extradition Law of 1977, extradition is conditional on the existence of an extradition treaty, unless the request is made by a commonwealth country, Section 9(2) of the CAT Act provides that the Minister may, in the absence of such an extradition agreement, by order published in the gazette, treat the Convention as an extradition agreement for extradition [in] respect of the offence … [of] torture. Extradition is also possible against those who aid and abet acts of torture.
