It is a pleasure to see the hon. Member for St Helens North (Conor McGinn) on the Opposition Front Bench. I have a lot of sympathy with what he said, and I hope the Minister will address the points he made, because we want to be constructive. We all support the overall thrust of the Bill, but my concern, as Chair of the Justice Committee, is that we do not do anything—albeit inadvertently and for good reasons—that undermines the checks and balances that are a normal part of the criminal process.
That is why the change in the burden of proof in relation to TPIMs needs more justification put behind it. Jonathan Hall QC, the independent reviewer of terrorism legislation, is highly regarded in this field, and the Minister has quoted him with approbation on a number of occasions. In this instance, he does not regard the case as being made out. If the Minister takes a different view, with respect, we need something more substantial as to why that is the case. There may be good reasons, but it cannot be done on a purely speculative basis. It cannot be on the basis that it may be useful to have this wider test. It might engage some people outside the jurisdiction in ways that we cannot currently in terms of gathering evidence and intelligence, but that case has to be made. Having voted on two occasions to increase the burden of proof to where it currently is, I would like to have a pretty clear sense that there is a compelling reason for reversing those decisions—and there may be, but I think the Minister owes it to us to set that out, and we need Mr Hall to set out why he comes to a different view. We may be persuadable, but it is important that the case is made and that the House understands that.
I accept that there is an overall three-year time limit on the working of the Bill, but I am concerned that, without a time limit, the TPIM will become the default mechanism and more like a control order. We surely all ought to recognise that, wherever possible—wherever proper, admissible evidence can be obtained and proceedings can be safely and securely brought—if people have done the vile things that we are talking about, which pose a real criminal threat to the security of this country and its people, the normal and proper course ought to be to prosecute through the normal due process. An alternative means of dealing with this should only be undertaken in the most exceptional circumstances. I can see that there may sometimes be such circumstances, but again, that case needs to be spelt out.
The third issue that I wish quickly to deal with is polygraphs. The Law Society takes the view that the suggestion of the use of polygraphs in some of these circumstances is more to persuade people psychologically —that is the phrase it uses in its briefing—against breaching the orders. That may be valuable in itself, but we ought to be wary of the limits of polygraphs’ usefulness. There are mixed views in academic, scientific and legal
circles about the reliability of polygraphs. I do not have a fixed view about them, but I think we should approach their use with caution and proportionality.
