See, I read that part of the Conservative manifesto as saying that there does need to be a review for the sake of not dragging stuff through the courts, as parliament and government should have more defined limits on what they can and cannot do. Technically what Boris did was right, but a court judged it differently which then put the queen in a sticky situation as ultimately she said it was okay, even though that’s not really a thing as the monarchy don’t get involved in that level any more. A clear definition would mean that there’s no more fudging or opposition parties voting against stuff or dragging decisions through the courts just to make a point, whether they’re right or wrong.
We’ve had a lot of tricky state vs government vs court questions with the whole Brexit thing, questions that no one ever thought would need to be asked. Makes sense to clear them all up for the future, whatever that means.
