Not until now, but I happen to be knowledgeable enough about immigration law that it's no big surprise to me. My primary worry is that because the executive branch does have extremely broad discretion over immigration enforcement and the scope of judicial review is somewhat limited, by law, the administration will be able to do enough damage on its own initiative that by the time disputes work their way through the courts the issue will be moot, as court proceedings are overtaken by facts.
Put another way, it's real hard to bring someone to justice for arson when you're inside the burning building. It might happen later, but in the short term that does little to remediate the risk to your life and property.
Allow me to suggest that you read and internalize this essay, because it is one of the few accurate summaries of out political reality that I've encountered in the past year.

I am nt arguing that politics is over and there's nothing that can be done any more, in fact I'm going to a city budgeting meeting in a couple of hours to find out/debate what to do about the imminent disappearance of federal funding. But your points about basic civics are redundant, I seriously doubt there's anyone reading or posting here who doesn't already know that.
