My right hon. and learned Friend is right.
That leads me to my final point, which goes to the heart of the Opposition’s amendment. It concerns the so-called Wiley balancing act, in which a judgment must be made on whether national security is more important than the administration of justice. Of course that is relevant for PII, because that is the absolute choice that has to be made in those circumstances, but the whole point of closed material procedures—unlike PII—is that the evidence will be available to the judge. The administration of justice cannot but be helped if the judge has access to all the relevant information. So the Wiley balancing act is simply not relevant in such
cases. The judge must be satisfied that there is a risk to national security, and he will have the last word on that. At that point, a closed material procedure will be granted, and that is the least bad option. We do not argue that CMPs are a good option, that they are desirable or that they are ideal. They are far from that, but they are better than the alternatives and, sometimes in this imperfect world, this is the only responsible way to behave.
