This is an incredibly important debate, because it goes very much to the heart of the views we take on what the Executive can do. It is anathema to our system that the Executive can impose restrictions on individual citizens on the basis of either the balance of probabilities or, worse, reasonable suspicion. Any restrictions placed must be justified, normally in a criminal court or, in the context of the current pandemic, by an exceptional event such as the pandemic.
All those who have engaged in this debate have accepted the need for some form of TPIM. On behalf of my party, I accept that too, but all our instincts should say that it should be on the most limited ground necessary at any point. I strongly opposed, as my party did, the idea that one can impose a TPIM on the grounds of suspicion alone and welcome Amendment 14, in which the Government reject that approach and go for a situation where the Minister “reasonably believes” that the person has been engaged in terrorist activity. The difference between “reasonably believes” and “balance of probabilities” seems in practice quite difficult to define; the Minister has to believe that the person has been engaged in terrorist activity and he or she must have reasonable grounds for believing so. What is the difference between having reasonable grounds on one hand and believing it on the balance of probabilities on the other, when the person who will test that is the courts? I think it is quite fine, but we will support government Amendment 14. I am grateful that they have listened; it is a very significant shift. The difference between honestly and reasonably believing something and suspicion is significant.
I am very disappointed that the Government persist in the idea that, once you have the basis for a TPIM, you can roll it over indefinitely. As various noble Lords have pointed out, the inclination of the Executive will be to roll these things over without further evidence. Therefore, we on this side of the House will also support Amendment 16.
Four years is a long time, longer than allowed at present and, what is more, the four years can be extended if new evidence emerges during that four-year period. We think there should be a limit on when a TPIM can be granted, where there is evidence for it. We would need new evidence to extend it beyond the four years. We think that four years is a long time, but we recognise that if the House backs this four years, that is the basis for a compromise we very much hope the Government will accept.
Amendment 22 would compel the Independent Reviewer of Terrorism Legislation to conduct an annual review in relation to TPIMs. I think that is right. I agree with everybody who has said that the independent reviewer has to be properly resourced to do it. This is such an exceptional power that I think it is right that the independent reviewer should look at it every year.
On the proposition that there needs to be a limit on the period of restriction that is required in a particular home, because the power is going to be amended to remove the reference to “overnight”, the Government have given assurances that there will be such a limit, because of the courts’ imposition of limits to ensure that nobody is imprisoned in their house for 24 hours a day, which is what the noble Lord, Lord Strasburger, said the consequences of the section would be. That is not my understanding, legally, of the consequence of the removal of “overnight”, but I would like the Minister to repeat that assurance and also to say that if the court protection went, the Government would come back to ensure that it could not involve 24-hour imprisonment, in effect, in a particular house.
These are exceptional powers. Our role in this House is to ensure that they are subject to specific limits. I think the combination of government Amendment 14,
Amendment 16, in the name of the noble Lord, Lord Anderson, and government Amendment 22, which would compel an annual review, is a workable compromise. I am very disappointed that the Government are not accepting it at the moment.
