We have had an interesting debate on these new clauses. I note that the hon. Member for Hammersmith (Mr Slaughter) described the legislation
as complex, controversial and important and asked whether I would accept his analysis. I agree that it is complex, inasmuch as we are dealing with the need for closed material proceedings and the nature of sensitive material. It is controversial and it is clearly very important, as it relates to the assurances we are seeking to give to overseas partners and, obviously, to the nature of justice itself, which was very much a feature of the preceding debate. In the context of his description, I certainly recognise the need for an assurance to this House and to the public about how the powers and provisions in the Bill will be used in practice, as well as on the points that have been made about that.
In essence, that question was at the heart of our debate in Committee about the utility, effectiveness and proportionality of the use of closed material proceedings and the frequency of their use, which, in many ways, touches on the point alluded to by my hon. Friend the Member for Chichester (Mr Tyrie). We have given an indication of how many cases are expected per year, but clearly the reporting mechanism we envisage is intended to provide a sense of how many times the provisions will be used in that way.
I shall focus on a number of points raised during the debate and characterise some of the themes that emerged. The first is the question of whether there should be a formal renewal process. The Opposition have sought to interpose an annual renewal through new clause 4, but even if we accept the principle, that is simply too short a time period for the reasons given by many right hon. and hon. Members. The House would not be able to assess the effectiveness and operation of the provisions, given that we are talking about cases that are likely to run for an extended period of time.
When we considered the timing and effectiveness of a renewal provision, going back as far as the Terrorism Prevention and Investigation Measures Act 2011, we looked back at what happened under control orders, which is perhaps the closest parallel to an annual renewal debate on which we can draw. I recall the annual debates on control orders and I am sure that the hon. Member for Hammersmith will agree that some of them were sub-optimal, to say the least. In many respects, they became—[Interruption.] They were not, perhaps, the kind of fully formed debate that the hon. Member for Hammersmith is seeking through new clause 4, because, in essence, they became a cursory discussion at the time for the annual renewal of the provision. The debates were often short, were not necessarily well attended and did not necessarily apply the level of scrutiny that he is looking for. It is difficult to see, if he is talking about a renewal 12 months after Royal Assent, what information would be available to inform consideration properly of whether the legislation was effective. If we put aside the detail of the principle, there is a clear issue with the timing.
