Quoted from another forum I frequent:
The problem is the Treaty of Union - the English Act states that the English parliament was to be dissolved and Westminster was to pop into existence. Varying the Treaty would require the agreement of the other party to it, namely, the political entity known as the Scots. I don't think that would be a problem, but Westminster would have to admit the supremacy of the Claim of Right (1989 and 1689) and Arbroath (1320), of course. They really don't want to do that I suspect, which is leading to all the nonsense about EVEL and the like. Most people don't really understand the nature of the Union and the Treaty - if you do, much becomes clearer (for instance, the result of the indyref didn't really matter - the definition of who could vote in it, and hence the definition of 'Scot', in 2012, was the really important thing).
So, for a devolved English parliament to come into being, the United Kingdom would need to dissolved and a new power structure negotiated. The extra spanner being those negotiations would then have to recognise the Scottish concept of "The People are Sovereign", which clashes with the English concept of "Parliament is Sovereign".
Hence the fudge of English Votes for English Laws.
I wonder if Tony Blair's "New Labour" really understood what sort of constitutional Pandora's Box they opened up when they set up the devolved administrations in Cardiff and Edinburgh and rebuilt the one in Stormont?
Probably not.
