Its a really weird use of the word government to not actually refer to the government but to the executive and saying the “courts are outside of the government” makes it seem like they aren’t a part of the state.

Consider though system like the Swedish system which existed in the Viking age with Things and a king.

Things were courts with huge power, and consisted of a gathering of all free men and had basically unlimited power, because they were the people. Meanwhile, the government was the person of the king.

I think that's an example of a system where the courts (Thing) is clearly not part of the government.

I'd say it's weirder to conflate state and government.

Why is it so weird that a language as widely spoken as English should have dialectical variation?

Wait ‘til you find out what some of my friends mean when they say “pavement”.

The important point is that courts have the power to overrule unconstitutional or unlawful government decisions.
