There were growing fears in Whitehall that the Scottish nationalists could hold London to ransom by voting down the Great Repeal Bill—which puts EU law into British law.
Britain’s devolution settlement was developed under the auspices of the EU single market.
The government now believes that the relevant framework should be reset at a UK level, in particular for devolved policy areas such as agriculture, fisheries and environmental protection.
But that requires the authorisation of all the devolved administrations in Cardiff, Edinburgh and Belfast through “legislative consent motions”.
A Conservative official said that there was likely to be sabre-rattling by the SNP during the process, which could take eight weeks, but said there were hopes that Holyrood would not stand in the way. “It’s common sense. There would be major consequences for Scotland if this wasn’t passed, there would be holes in the law,” he said.
The Guardian’s Andrew Sparrow, earlier this evening:
This is a consequence of what is known as the Sewel convention, which says the Westminster parliament should not legislate on matters devolved to Scotland without the Scottish parliament’s approval.
As we learned earlier in the year, the Sewel convention is just that—a convention—and is not (as far as I believe) enforceable by the courts1. The UK Government, however, has thus far not (as far as I’m aware) overridden a vote in the Scottish Parliament. It seems that it could legally do so but in such a scenario we would be in uncharted constitutional waters.
Update: The Guardian has published an article looking in more detail at this issue. The piece includes quotes from Mike Russell, the Scottish Government’s Brexit minister, and Graham Matthews, president of the Law Society of Scotland.
