My Lords, very briefly, given the hour, I think we can all agree that the independent reviewer is not only a formidable lawyer but a master of modern communication with his blogs and tweets.
I welcome the broad support for Amendment 16A given by the noble Lord, Lord Butler. I want to press the Minister a little on some of his replies: first, on the potential clash with the Independent Chief Inspector of Borders and Immigration. I have just tried to flick through his last annual report but I do not think that he touches on anything to do with national security or powers linked to counterterrorism. As the noble Lord, Lord Butler, has just said, there is a way of dovetailing to make sure that there is no clash. What Amendment 16A proposes is very much to the extent that immigration and nationality law is used for counterterrorism purposes, which is not broadly the focus of the borders and immigration inspector.
Then there was a reference to a one-off review of Section 66, on deprivation of citizenship. However, a one-off review is not the same thing as continuous review and monitoring, so that is really apples and pears.
I join the noble Lord, Lord Butler, in wondering about the Secretary of State at some point, possibly several years hence, appointing an overseer of Part 2 of the Justice and Security Act. The Minister said that that person could be the independent reviewer. Why wait? Why risk setting up two separate posts, which would be inefficient and potentially add some costs? Why not short-circuit the exercise by deciding now to give that function to the independent reviewer? As my noble friend Lady Hamwee said, the case-by-case judicial oversight of the court is not what is meant here by the independent reviewer’s role in having that overview of the way that Part 2 of the Justice and Security Act, on closed material proceedings, has been employed in a whole string of cases. It is rather different. I would press the Minister to give a little more justification as to why Amendment 16A is not feasible.
Lastly, I may not have heard the Minister correctly—it may, again, be the lateness of the hour—but I am not sure that he gave an in-principle explanation of why it is not possible to have a statutory basis for the access to secret material. Of course, I accept what he and the independent reviewer have said—that in practice there has not been a problem and that if the Government tried to be obstructive, we would all know about it pretty soon. However, I do not think that he explained what the policy, or legal or other difficulty, is.
