Yes, because we want a process whereby the judge can hear the evidence of the intelligence agencies in a closed—secret, if one likes—process, and that is not the purpose of PII. PII is a very old process that has developed over the years from simple beginnings, and I imagine that in the early cases—before my time—it was probably rather straightforward: if a Minister said he wanted public interest immunity, it was granted. The findings of Lord Justice Scott in the arms to Iraq inquiry —not at my expense, I am glad to say—rather upset that approach. PII is of course used flexibly in proper cases because judges and lawyers all want to hear evidence in open court whenever possible, but I think that we need to update all this. We are not abolishing public interest immunity, but I think that in many cases extending closed material procedures, which is what we are proposing, would be an altogether more sensible way of getting a proper judgment in the case.
Let me turn to the provisions of the Norwich Pharmacal jurisdiction.
