Scotland Bill

My Lords, I think that we will have to differ on the construction of powers under the 1998 Act. However, I am quite clear on it. Now, instead of an Act with a construct providing for a general power for the Scottish Government to make requests to the UK Government, and for the UK Government to accede to those or not, and because we are now getting to a very significant devolution of tax powers, it is entirely appropriate, as I hope my noble friend will agree, that if such devolution is to go ahead as the Government wish, the full structure should be set out as it is in this Bill although not in the 1998 Act. I hope that that explains that one. Perhaps I should carry on with air passenger duty, which is the narrow but important subject of these amendments.
