The UN Committee against Torture (CAT) criticised the United Kingdom for not ensuring that evidence which may have been obtained through torture by third states is never submitted in immigration proceedings under the Anti-Terrorism, Crime and Security Act 2001. Indefinite administrative detention, practices connected to diplomatic assurances in the context of non-refoulement and the application of minimum guarantees, such as post-return monitoring arrangements and due process guarantees were also raised as concerns by the Committee. Recalling the extraterritorial application of CAT the Committee called on the UK to make public the results of all investigations into alleged misconduct by its forces in Iraq and Afghanistan.
