My Lords, on the last occasion, the noble and learned Lord, Lord Lloyd of Berwick, gave the example of a man who was acquitted of a murder of which he was in fact guilty. That was the noble Lord's premise. The man later admitted the offence to his wife. I gave the example of a man who was acquitted of a murder and subsequently bragged that he was guilty. In both those cases a murder was committed and the murderer walked free from the original trial. If there is new and compelling evidence, I do not see the injustice, subject to the safeguards that we have discussed, of that person being brought to book.
