Counter-Terrorism and Sentencing Bill

My Lords, I do not have anything to add on the substance of the amendments which my noble friend Lady Hamwee has outlined. However, I would like to go back to something that my noble friend Lord Thomas of Gresford raised in relation to the use of polygraph tests on convicted terrorists who were subject to licence: the right to silence. Quite rightly, the noble and learned Lord who was the Minister at the time said that, because these people would be convicted offenders under licence, they had no right to silence. But TPIM subjects are not convicted offenders on licence; they are unconvicted. That is the whole idea of a TPIM, and so they do have a right to silence. The question for the Minister is: would it be a breach of TPIM conditions, which is a criminal offence for which the person could be sent to prison, if they refuse to participate in a polygraph test or if, in a polygraph test, they refuse to say anything?
