Retained EU Law (Revocation and Reform) Bill

I seek clarification about the amendments of the noble Baroness, Lady McIntosh, and the noble and learned Lord, Lord Hope, on the power that Secretaries of State have on extension, and so on. The Minister said that it would be if the devolved Administrations request it. Does that mean that the request will be granted? This affects the settlement we have on devolution and our union. As he says, for everything for which they have responsibility they will change, amend or keep it, but if they want an extension on the sunset, they have to request it. Does that mean that, if they request it, it could be refused?
