"However, the UK Government will proceed in accordance with the convention that the UK Parliament would not normally legislate with regard to devolved matters except the agreement of the devolved legislature."
My Lords will notice with regard to devolved matters, that is the first question that would arise, is any piece of legislation with regard to devolved matters, but we don't know until we see it.
Secondly, even if it is with regard to devolved matters, what is Parliament expressing? It is expressing what amounts to a self-denying ordinance, albeit a qualified one. If it is with regard to a devolved issue, and we are not there, but if we go past that, then normally we will not legislate in respect of that. But it is our self-denying ordinance, and indeed, that was brought out by an observation that in fact I have already touched upon by my Lord, Lord Reed in the case of Imperial Tobacco v Lord Advocate, which is at volume A5, tab 41, MS 1592, but particularly paragraph 71 at MS 1619.
