My Lords, I thank noble Lords who have participated in the debate on these amendments, and the noble Lord, Lord Elis-Thomas, for bringing them forward. I am well acquainted with his burning passion in relation to these matters, which I know we have discussed many times before.
I turn to the amendments, through which the noble Lord and the noble Baroness seek to extend the common law-type powers of Welsh Ministers. I shall break off and explain what I think that means to the noble Lord, Lord Howarth. The issue here is that, yes, common law grows up over a period of time, mostly, though not exclusively, from the contribution of judges—some of it would be by convention in other ways, I think. Here we are seeking to confer these types of powers on Welsh Ministers. We cannot do that by the effluxion of time, because time has not allowed that, so we are taking what is already the position in relation to the common law powers that exist for UK Ministers and saying that we believe that those types of powers should exist for Welsh Ministers. We are transposing them because we cannot build in the period of time element.
It is our view that these amendments would undermine the protection given to a very limited number of Minister of the Crown functions, which the Assembly may modify only with the consent of United Kingdom Ministers. Clause 18 is a key part of delivering the clear settlement that we putting in place through this Bill. Ministers of the Crown and Scottish Ministers already exercise these common law-type powers. This clause would put Welsh Ministers broadly on the same footing as Ministers of the Crown and Scottish Ministers by ensuring that in future they too will be able to exercise such common law powers.
The noble Lord, Lord Elis-Thomas, asked a very fair question in relation to the royal prerogative. I am very willing to meet with him to discuss this further
but, so far as we have been able to ascertain, the royal prerogative has not been conferred on Welsh Ministers. They derive their powers from transfer of function orders or under the legislation. The noble Lord probably knows more about the royal prerogative than I do; I am very happy to meet with him on this issue.
