Re: Arbitrary law is reappearing
The attempt to distinguish between the PM's actions and the will of Parliament is doomed. In constitutional terms, the PM is nothing but the spokesperson of Parliament (ignoring the House of Lords which has no serious relevance).
The PM is the leader of the majority party - or of a coalition should no party have a workable majority. The will of Parliament, of course, is determined by majority voting. Thus, constitutionally speaking, whatever the PM says and does must express the will of the majority in the House of Commons.
To attempt to drive a wedge between the government and the House of Commons, as the Supreme Court decision did, is to create a distinction where none legally exists.
Divide and conquer.
