I do not dispute any of that; that is where I am coming to with respect to the attitude of the special advocates. Clearly, of the two they do not like
CMPs, for reasons that I am about to elaborate. That means not that CMPs should be impossible to use, but that restriction should be the order of the day.
The best outline of the weakness of closed material procedures came from Lord Justice Kerr, who effectively said—I am now desperately paraphrasing—that unchallenged evidence can be “misleading”, which was the word he used. That came up any number of times during the Lords debate from a number of lawyers. Helena Kennedy, for example, cited a case in which a tape recording of a conversation that appeared to incriminate a defendant was played in court. When the defendant heard it, he said, “I’m sorry, but I left after about five minutes.” People listened carefully and could hear the door opening and closing as he went. So a piece of evidence that appeared to be incredibly incriminating became not incriminating at all. David Anderson put a similar point to the Lords Committee when he was giving evidence.
The issue of challenge is important; it is critical to our judicial process—completely different from any other judicial process around the world. The challenge is vital. Without it, the judicial process is not operating properly. That is why we have to take on board what the special advocates say and effectively build it into the structure of the Bill—to create, as it were, a hierarchy. We have to go through that thought process.
I am cognisant of the point made by the Minister without Portfolio. We do not want a Minister to be pinned down for a year working on one PII. I am sure—indeed, I know from experience—that some of the Guantanamo cases are incredibly complicated and involve very many documents. I do not think it is beyond the ken of the House to achieve that.
I will support the Opposition’s amendment today, although I am open to argument if we can find better wording to get what we are trying for. I am talking about a hierarchy, a priority—first, open hearings; then the PII process, if that is appropriate; if it is not, CMPs in the final analysis. I agree with my right hon. and learned Friend the Member for Kensington (Sir Malcolm Rifkind) that the process should be more open than it currently is.
