Counter-Terrorism and Sentencing Bill

Debate between Lord Falconer of Thoroton and Baroness Hamwee

Committee stage & Committee: 2nd sitting (Hansard) & Committee: 2nd sitting (Hansard): House of Lords
Tuesday 9th February 2021 Lords Chamber

[Lord Falconer of Thoroton (Lab) [V]]

This amendment proposes that the Secretary of State, within six months of the Bill being passed, should set up a pilot to see how the polygraph condition works in relation to terrorist offenders. It is a probing amendment. It may well be that a different or longer period would be required for the pilot, but the purpose of a pilot is to test a number of aspects of polygraph testing. We have gone through this on the previous group, and I do not want to spend too much time on it because we have already discussed it a lot, but I have three particular concerns that would be tested by a pilot.

First, how does polygraph testing operate in practice? I would be grateful if the Minister, who was very helpful on the previous amendment, would give us some indications about how it works in practice. By that, I mean the following. If one asks a question of an offender in a polygraph test, “Did you, in breach of your conditions, visit a certain place?”, and he gives an answer to which there is—to use the language of the Minister and the briefing—a significant response, does that mean that further investigations take place? If there is no significant response, would that mean, for example, that there would not be any further investigation? Does that give rise to risks that too much reliance will be placed on the answers in polygraphs to, for example, not undertake further investigations?

My second area of concern is the one raised by the noble Baroness, Lady Hamwee, on Amendment 19. It would appear from the very helpful answer given by the Minister on the previous group that answers given would be admissible in proceedings against another offender, albeit that their admission would be subject to the discretion of the trial judge for the other offence. In certain circumstances I can see very clearly that they might be of real evidential value—for example, because they constituted an admission or because they constituted evidence of a conspiracy, depending on the content of what is being said. Can I take it that the Government are saying that they might in certain circumstances be admissible and that they are content for that to be the position? It is important that the Committee knows what the position is.

Thirdly, am I right in saying that decisions about recall are made not by a court but by a probation officer, and are there any reasons why he or she should not rely on a significant response—to use lay man’s language, a failure—of a polygraph test? I beg to move.

[Baroness Hamwee (LD) [V]]

My Lords, the questions that have been asked are important. We cannot assume that the rules that currently apply for use with sex offenders are going to apply in terrorism cases. Indeed, Clause 35(2) tells us that there may be particular rules for terrorism cases, and even if that was not in the Bill, we know that rules can be changed at any time, relatively easily.

Polygraphs do not have a great reputation with the public, and “The Jeremy Kyle Show” did not enhance it, which is another reason for wanting to explore details today. I made the point only yesterday on the Domestic Abuse Bill that operators have to follow courses accredited by the American Polygraph Association, and I was interested—I will try to use a neutral term—that we in this country are following American practice.

Under the rules, there are requirements about reports and records. I had a look at the 2009 rules, under which the operator is required to explain the requirements of the session: that anything disclosed might be communicated to the probation officer, and that there must be consent—or, rather, written confirmation—from the offender that these explanations have been given. I stopped myself calling it “consent” because, in that situation, I wonder whether the anxiety to which my noble friend Lord Thomas referred would preclude a complete understanding by the offender of what is happening. In that situation, knowing that refusal to take a test would amount to a breach of licence conditions, would you not sign anything?

The current reviewer of terrorism legislation has called for a pilot, and, if not a pilot, then post-legislative scrutiny. Not many Bills come along for post-legislative scrutiny by Parliament. The noble and learned Lord, Lord Stewart, painted a picture that I did not quite recognise. It sounded rather more like a departmental review—an internal review—than scrutiny by Parliament to see how an Act is getting on.

At last week’s briefing, I asked about the reliability of polygraphs used on subjects who have undergone some extreme experiences, such as having been in a war zone. I understand that that cohort is particularly in the Government’s mind at the moment. The professor of psychiatry—Professor Grubin, I think—who, I understand, advises the Home Office, realised that I was referring to trauma. I had not wanted to assume that they were subjects who had been traumatised, but he was right. I remain concerned not only about what might be perceived from offenders’ reactions but that the test itself might be retraumitising, so I think that the questions being posed are very helpful.
