The general principle referred to by the noble Lord, Lord Turnbull, which has been very clearly enunciated by the courts, is that no public authority, including local authorities, has the power or statutory authority to exact money that exceeds the amount that the local authority—or other person making the imposition—sets. The charge the person is required to pay must be just equal to the amount that will be needed to carry out the service, or other thing. If it does, it is taxation and that covers all forms; it does not matter whether it is a payment, charge, fee or anything else. That is a general principle. Therefore, the provision in Clause 7(7), preventing the regulations imposing or increasing taxation, prevents any local authority or other power having the power to make any such imposition.
On the amendment proposed by the noble Lord, Lord Lisvane, I wonder whether the first part of the clause —Clause 8(1), I think—is the subject of Amendment 126. My noble friend Lord Deben wondered why we were talking about this in a withdrawal Bill, but the clause says that we may have an international obligation that is breached by withdrawal; it therefore seems reasonable to deal with that in the withdrawal Bill because it is a consequence of withdrawal. That amendment implies that this power cannot be used to make any financial settlement that would cause a cost to the United Kingdom because if it did, it would inevitably require taxation—presumably, whoever makes the settlement does not intend to defray the cost out of his or her own pocket. It is a fundamental restriction on the way in which these matters of international obligation may be resolved. I think I am right in that, but no doubt the noble Lord will tell us its effect on the amendment in due course.
