Evidence obtained by Torture cannot be used against terror suspects.
This is the main point of the decision of the House of Lords, just published. You can find the decision here.
The House of Lords reached the decision by Unanimity in this extrimely delicate issue. This is particularly astounding, given the conservative views of some of its members. Read in particular Lord Bingham's opinion.
Amazing decision, it will cause a lot of debates. No doubt!
