My Lords, I am grateful to the noble and learned Lord for giving way. He is right in the very general statement that he makes. But we must bear in mind that, when drafting legislation, especially that dealing with people's rights, if we express one thing and omit the other there is an assumption that the other is necessarily admitted. There is a well known Latin phrase for that, but one must not use it now. I would have thought that it could do no harm, but would clarify matters, if the rights of the defence were inserted in the way that my noble friend has so wisely suggested.
