Sure, which is why the judicial branch reviews such decisions, and has reviewed this one and has come to the conclusion that it was justified. Just because you don't like their ruling doesn't make it not binding.
Their ruling is not final yet, per the article. I'm also free to disagree with the correctness and propriety of a judicial ruling and believe it was biased (of course, I do have to still abide by it, to the extent that it applies to me in any way). That it's binding doesn't mean it's right and that it is in accord with the law and/or the constitution.
A judicial ruling is by definition in accord with the law or constitution (because it literally becomes the law) whether you or I like it or not, if and until such a time as it is overturned.
No, I don't think that's correct. Humans are fallible, and just because a court says that something is in accord with law/constitution, doesn't mean it actually is.
That distinction is academic, of course, because when the courts decide a certain way, then of course that's how things will play out.
Well, except when the Trump admin ignores court orders.
