Council Tax Valuation Bands Bill [HL]

I should explain retrospection, since my noble friend Lord Marlesford is on the point—and my noble friend on the Front Bench made the same point. What is proposed, if it is going to look back to anybody who bought a house before 2000, is to tax people on their past choices and on potentially capricious values. I do not think that that is a very fair way in which to proceed. In that sense, it is retrospective but, obviously, it would come into force and go forward.
