You never have one except because everyone decides they do. The moment anyone with a modicum of power decides to say it doesn't exist, it doesn't exist.
> In 1942 there were 110,000 Japanese-American citizens, in good standing, law abiding people, who were thrown into internment camps simply because their parents were born in the wrong country. That's all they did wrong. They had no right to a lawyer, no right to a fair trial, no right to a jury of their peers, no right to due process of any kind. The only right they had was...right this way! Into the internment camps.
> Just when these American citizens needed their rights the most...their government took them away. and rights aren't rights if someone can take em away. They're priveledges. That's all we've ever had in this country is a bill of TEMPORARY priviledges; and if you read the news, even badly, you know the list get's shorter, and shorter, and shorter.
From the outside, it continues to surprise me when people bring this up, as if they're either too ignorant to know about the Dixiecrat schism or want to pretend that everyone else is. What's the point? It's so easy to look up.
It's just propaganda, optics, PR. Obviously the Democrat party in 1940 has absolutely no relation to the Democrat party in 2025, except for the name. People use that same name to smear the 2025 party because they can. And it works because propaganda works. That's how Germany got Hitler and it's how the USA got Elon.
I think it’s important to clarify that in this case, having a “modicum of power” is in the form of being able to say it doesn’t exist without a riot and a beheading. It’s not in the form of money or command of an army, though those things definitely help.
Really, in democratic societies there are three levels; those where the offending politician is actually deposed, those where their unconstitutional action is blocked by the courts or by another arm of government (as with Boris), and those where _they never do the thing in the first place because they realise they can't get away with it, and there'll be unpleasant consequences for them_ (this is by far the most common, particularly in parliamentary democracies, where Dear Leader can be fired at a moment's notice). If none of these happen, then typically the democracy ends.
The US is probably unusually vulnerable to this sort of thing; it has an unusually powerful executive, and a highly politicised Supreme Court, in particular. Though, it kind of remains to be seen how far the Supreme Court will be pushed. Some or all of Trump's appointees may take the view that they got into the job to screw over minorities and aid business, but not necessarily to actually end democracy in the US. They are likely not all that beholden to him.
R v Miller was important but ultimately overtaken by events - while Parliament did want to discuss Brexit, they were unable to find a viable solution and we still got no-deal Brexit where vital things like the status of Northern Ireland had to be patched up later. For whatever insane reason, the demand to eject us from the Single Market was just too strong.
R (Miller) v The Prime Minister (not to be confused with R v Miller, or R (Miller) v Secretary of State for Exiting the European Union (the solution here is clearly to just stop naming people 'Miller', to avoid further confusion)) was probably ultimately more important in its precedent than its concrete outcomes, though, yeah.
