Extraordinary assertions keep being made outside this House that the Bill allows Ministers to decide whether there should be closed
material proceedings, but that is complete nonsense. The “must” to “may” amendment arises in circumstances where the judge who takes the decision decides that national security would be at issue. The original Bill said that once he finds that there is a risk to national security, he “must” have a closed material procedure. Such is the concern of all these critics that we have made it clear that we will accept a wider discretion, so even when the judge—not the Minister—is satisfied that national security is at risk, he “may” have a closed material procedure. I submit that people should think about the possibility that that leaves the judge with all the discretion in the world to think about all the other issues that might mean there is some compelling reason in a particular case not to allow a CMP, even when national security is threatened. I simply do not understand why the right hon. Gentleman—he is not the first; I am not singling him out—and others keep asserting that Ministers will decide on that when the Government gave up that position months ago.
