My Lords, the noble Lord, Lord Hodgson, with great force and fervour, invites the House to consider that a silver bullet from this place and the other place is perhaps not a bad thing at all. That may well be so, and both Houses are entitled to fire silver bullets by way of resolutions, debates and in a number of other ways, but not in their legislative capacity. That is really all that this issue is about.
There are only three areas of law—or at least there used to be when I was a law student a very long time ago—statute, common law and custom. If a statute is to have any purpose or meaning at all, it has to change to some extent one at least of those three areas. Custom can be left out of it; it is agreed universally that it does not change the content of a statute by one hair’s breadth. There was, I think, some dubiety in Committee about common law, but I honestly think that that is answered by a long-standing principle in our law—namely, that a statute to change the common law has to say so expressly on the face of it and to make it clear beyond peradventure or doubt that that is happening: otherwise, there is a presumption that the common law is not changed. I should have brought Maxwell’s Interpretation of Statutes along with me but I am sure that the Minister will accept that that is still a fundamental principle of our law. The right to legislate is a sovereign right and privilege to be used sparingly. It is not to be used for propaganda purposes.
