Not sure what you're referring to.

The whole argument about the referendum being non-binding.

As a matter of democratic government, the people were given a say in a referendum. That referendum was, as far as I can tell, properly conducted according to the rules known in advance. By the standards of any national vote, including things like general elections, the turnout was high, and while the margin was not huge, the option that received the most votes was clear. Both MPs' intent and the people's expectation before the vote was apparently that the decision being made was final.

Beyond that, one can argue about legal technicalities and constitutional nuance, but it doesn't change the result. Disregarding that result, in the absence of a further popular vote or other similarly authoritative step, would IMHO have no popular mandate, without which again IMHO a government has no legitimacy in the first place.

(Just to be clear, my whole argument here is really about the democratic legitimacy of the process. The integrity of our system of government is, to me, a higher priority than any individual decisions or actions by any current part of the government, just as in other situations I might defend someone's right to express an opinion even though I personally did not agree with it.)

It's their job to make good laws, not just to give speeches suggesting what their unwritten intentions may be.

Indeed, but it is an imperfect world and even legislators and lawyers sometimes leave ambiguity in their wording. When that happens, we need to take some intelligent and hopefully fair and transparent view on how to interpret the law in question.

As it happens, there does seem to be some legal precedent for considering what was said in Parliament in the process of making the law to resolve such ambiguities. The House of Lords changed the previous standard of considering Parliamentary commentary as privileged and allowed the use of material from Hansard under some conditions, in Pepper v Hart. I was a little surprised that the Leave side didn't try to rely on that sort of argument during the court challenge.

That may well be, but it does not invalidate the legal argument behind it.

Indeed. But equally, a legal argument can never invalidate a moral/ethical one. If the view of the people on a specific matter has been explicitly asked and answered, I struggle to accept a government that then disregards that view as legitimately representing its people.

Take the Supreme Court's. Do you really think its ruling is "using sophistry to undermine democracy and civilised government"?

Assuming we're talking about the Supreme Court case regarding whether the government had to consult Parliament before triggering Article 50, as far as I know these kinds of arguments were not pursued in detail.

I haven't read the whole thing, but my understanding is that both sides stipulated that the referendum was non-binding, the enabling legislation didn't explicitly give the government the power or obligation to do anything specific after a leave vote, the government didn't attempt to invoke Pepper v Hart or any similar implicit authority, and the action the government wanted to take would have legislative effects. How could the Supreme Court have reached any other decision than it did if those were the facts of the case and accepted by both sides?

No doubt such senior judges were considering all kinds of details carefully before reaching their decision, but it seemed to me at the time that the government never really presented much of an argument.

I don't understand why you don't blame this on the MPs who had the power to prevent it.

I don't think MPs did have the power to prevent it, though. As a matter of law, it seems our highest authorities accept that Parliament currently has no mechanism to legislate for a binding referendum. If MPs had been more explicit in the Referendum Act then it might have saved everyone some time and hassle, but it's hard to believe it would have entirely avoided all the debate over whether the result was binding given the controversial nature of the subject.

My personal view is that the best way to avoid such problems would be to have a proper written constitution that provided explicitly for binding referendums on matters of such importance as part of the machinery of government. Sadly, I have yet to be named Supreme Ruler Of The Universe, and so implementing such a constitution is beyond my power. For now. ;-)
