I am conscious of the time, and I want to make a few more points, if my hon. Friend will forgive me.
This point goes to the heart of what Lord Woolf, the former Lord Chief Justice, has said. The plaintiffs themselves will sometimes benefit from the arrangements, as well as the Government who are defending the case. I can think of current cases, some of which are controversial, in which information given to the judge about the activities of the intelligence agencies some years ago could well help the plaintiff as well as the Government.
Furthermore, if it was suggested that a particular closed material procedure had been drawn too widely to include information that did not need to be protected, the benefit of the special advocate system is that if the advocate was doing their job properly, they would raise the matter with the judge. If the judge was satisfied that the breadth of the closed material procedure needed to be reduced, the evidence in question could be heard in open court.
