In other words, when it has been decided that a devolved nation has the right to decide on an issue then its consent is sought to Westminster legislation if it relates to that area of activity. There is, of course, a corollary. Because we now have EVEL – English Votes on English Law – Scottish MPs cannot vote on English legislation. So, Scotland is ring fenced from English decision making. Legal Consent Motions might be seen as ring fencing English MPs from Scottish decisions.
And in that case, and because Brexit very clearly does impact Scotland in ways Scotland may not want then of course it is right that Scotland must have the right of veto in this issue. Without EVEL I would find that vey hard to justify. But Cameron demanded EVEL. And his party has to live with the consequences. Whether or not we leave the EU may be down to Scotland. And it’s all Cameron’s fault.
Note the leap there. From “has a right to decide upon” to “should have the right to decide.”
The Scottish P gets to vote on things which we have already decided the Scottish P should get a vote on, even if the legislation is going through Westminster. Is Brexit already a devolved issue?
