Click on the title to read the legal opinion rendered to the British Parliament by Michael Fordham QC.
A synopsis of the opinion can be found in the Guardian:
The conclusion reached by Fordham and his colleague Tom Hickman is that an offence would definitely have been committed. If acted on, the opinion could mean that UK troops would not be allowed to "render" detainees to the US military until it was clear that they would no longer face the possibility of torture or ill-treatment.
What prompted the inquiry was a statement made in February this year by Ben Griffin, a former SAS soldier who was on active service in Iraq. In his statement, Griffin said that he was "in no doubt" that individuals handed over to the US military "would be tortured". He cited what had happened to those detained at Guantánamo Bay, Bagram airbase and Abu Ghraib prison.
The opinion adds: "UK forces operating in Iraq are potentially also subject to UK criminal law, tort law and Iraqi law. Notably, the Criminal Justice Act 1988 makes it a criminal offence for a public official, whatever his nationality and wherever located, to commit an act of torture."
