Counter-Terrorism and Sentencing Bill — House of Lords, 2021-02-09
Topic: Law and Crime
Jonathan Marks (Liberal Democrats, Centre to centre-left): My Lords, as my noble friend Lady Hamwee and others have explained, Clause 32 puts the imposition of polygraph conditions on serious terrorist offenders released on licence on the same footing as applies in the case of serious sexual offences. I say at the outset that I agree with the noble Lord, Lord Faulks, and my noble friend Lord Thomas that different considerations apply with terrorist offenders and sexual offenders Yesterday, in Committee on the Domestic Abuse Bill, we discussed the use of polygraph testing for domestic abuse offenders released on licence—and again, different considerations apply. Nevertheless, I said then that my outright opposition to the use of polygraph testing anywhere in our criminal justice system had become more nuanced when the proposed use was for the limited purpose of monitoring compliance with licence conditions on release from custody. My outright opposition hitherto stemmed from the lack of proven reliability of polygraph testing and from the perception at least that it is directed to providing binary answers, true or false, to complex evidential questions—hence the use of statements such as "He failed a polygraph test". Lawyers naturally prefer a system which depends on the careful and balanced evaluation of evidence, often conflicting or inconsistent, rather than certainty In part, as I said yesterday, I have become more sympathetic to the use of polygraph testing with the help of the comprehensive and very helpful learning session organised by the MoJ last Thursday, which was attended by a number of Peers, including the noble Lord, Lord Faulks, and my noble friend Lady Hamwee, as they have said. In addition, I accept that there are legitimate reasons for the use of polygraph testing to provide information to the police and others investigating serious offences and, in the case of terrorism, often potential offences that threaten multiple lives. However, accepting polygraph testing for those limited purposes does not mean that we can accept polygraph testing in criminal cases, and that will remain our position unless and until the reliability of polygraph testing is far more conclusively established than it is now. I agreed completely with the observations of my noble friend Lord Thomas of Gresford on how stress can affect evidence given in a court and on how falsely polygraph testing may skew such evidence Our Amendment 19 would amend Section 30 of the Offender Management Act to ensure that evidence of any statement made by a released defender in a polygraph session, and any of his physiological reactions while being so examined, could not be used in a criminal prosecution of any person, not just the released offender. It is right that this amendment is billed as a probing amendment, but that is plainly right. However, at the moment, Section 30 does not say that. As the noble and learned Lord, Lord Wolfson, said yesterday in answer to me on the domestic abuse provisions: "Section 30 of that Act provides unequivocally that any statement or any physiological reaction made by an offender during the polygraph session may not be used in criminal proceedings in which that person is a defendant."—[Official Report, 8/2/21; col. 41.] Therefore, the Government accept the principle that evidence obtained as a result of polygraph testing, or flowing from physiological reactions under such testing, cannot be used as evidence in a prosecution brought against the person being tested. It must be right that it should not be possible to use such evidence in the prosecution of anybody else, and the reasons mentioned by my noble friend Lord Thomas apply equally to that situation It therefore seems that, while this is a probing amendment, it is an amendment that the Government can and should plainly accept without compromising their position or anything that the Bill is trying to achieve, and that it is simply consistent with the position taken by the Government that polygraph-testing evidence cannot be used to secure a criminal conviction I stress, in the context of the danger posed by terrorism, that I take the point made by the noble Lord, Lord Faulks, that deradicalisation is difficult to achieve. He described it as a holy grail. I emphasise that nothing we say would prevent those administering polygraph testing to released offenders from passing on to the police for the purpose of preventing terrorism information revealed to them. Nor should the police be inhibited from using such information passed on to them in investigating and avoiding terrorist offences Amendments 19A and 19B would have the effect of insisting on the affirmative resolution procedure for regulations making provision relating to the conduct of polygraph sessions further to a terrorism-related offence. I suggest that the need for the affirmative resolution procedure is obvious. I would be grateful, however, if the Minister could confirm a number of other points about the regulations proposed, not just for the conduct of polygraph sessions but for using information obtained in the course of such sessions in relation to recall from licence My understanding is that, as with sexual offences, and as we were assured yesterday with domestic abuse offences, no decisions on recall from licence can be taken as a result of a test indicating deception. If the result of a test implies that an offender is lying about breach of a licence condition or about further offences, for example, I understand that investigators may ask the police to investigate further before taking any positive action. There is therefore to be no recall on the basis of a failed test, which will lead to recall only if the police find other evidence establishing that a breach has occurred. I hope that will be confirmed in a terrorist context as well I also have some concerns about cases where an offender makes a disclosure in a polygraph test, confessing to behaviour that is a breach, and who might therefore be recalled. I asked yesterday about this and was told by the noble and learned Lord, Lord Wolfson, that recall in domestic abuse cases may follow if "disclosures made voluntarily by the offender during the polygraph examination … reveal that they can no longer be safely managed in the community. Those circumstances would also lead to a return to custody. The important point to bear in mind in that regard is that that is no different from a situation in which an offender makes such disclosures without the polygraph licence condition."—[Official Report, 8/2/21; col. 41.] I take that point, but I regard it as important that, before a disclosure in a polygraph test can lead to recall, there should be a hearing where the disclosure is either admitted by the offender to be true or can be tested so as to ensure that it is voluntary, genuine and true before a recall based on it is affected Yesterday I posed a number of questions to the Minister in relation to domestic abuse polygraph conditions. They are reported in Hansard, but the same questions are pertinent today in connection with this Bill. They concerned in particular: first, a guarantee that the results of polygraph testing carried out under the clause could not be used to secure convictions of a criminal offence; secondly, that recall from licence on the basis of a disclosure in a polygraph test of a breach of a licence condition will not be possible without a further hearing—the point I just mentioned; and, finally, whether evidence of a breach of a polygraph licensing condition could ever be itself based on evidence from a failed polygraph test. It would be helpful to have those answers in the context of this Bill relating to terrorist offences as well.
