That is an interesting response and I will have to think about it. I share the concern of the noble and learned Lord, Lord Judge, not to involve the Executive where it should not tread. There could be parliamentary scrutiny. We have become possibly too reliant on codes of this and that to flesh out what lies underneath legislation—it is not something I much like, and I have obviously been sucked into it. So we could have parliamentary scrutiny if we had a statutory instrument, but we could also list in the Bill the sorts of examples we have talked about, in the way that the amendment from the noble Lord, Lord Anderson, and the noble and learned Lord, Lord Judge, seeks to do in Clause 4. I think that that is a particularly good way of going about it.
I do not suppose the Minister can answer this, but his reference to the Independent Reviewer of Terrorism Legislation prompts me to ask about progress in appointing the new reviewer. He is indicating that he cannot answer, and I did not expect him to, but it is a point that was worth making at some stage in this debate.
