I'm having trouble understand @Jazzhead point. How did those DACA folks put themselves in danger by believing in Obama and filling out papers? Aside from the fact, that is is a mortal sin to believe anything Obama said, that is.
Emjay, the legal concept is called detrimental reliance. One party changes his position in reliance on the promise of the other party, who then breaks the promise. Here, approximately 700,000 folks came forward in response to the DACA program, letting the government know who and where they were, in exchange for renewable work permits and the chance to live life "above ground".
Yes, I understand that many here opposed DACA from the beginning, and some here harbor true animus towards these folks (even though their unwanted presence here is not because of their own actions). Yes, I agree with President Trump's position that he cannot continue the program unless and until its legal underpinnings are confirmed by Congress. As things now stand, the court agrees that Trump may suspend new DACA enrollments (approximately half of those ostensibly eligible for the program have come forward).
But what of those who enrolled in good faith, and demonstrated their ability and willingness to work, educate themselves, or otherwise serve the community as the program requires? They've come forward, and as far as they know if they cannot continue in the program they will lose their jobs, lose their status, and face deportation. Are these folks "in danger", as you snidely suggest, for "believing in Obama"? I don't know, but I do know that one poster in this thread, a proud Christian warrior, has told them to go eff themselves. To another, they're just contemptible "squatters".
There's not a lot of empathy here for folks whose parents brought them here many years ago from shithole countries in search of work and a better life.
Yeah, I think they satisfy the legal definition of harm by reason of detrimental reliance. I therefore understand why the judge ruled as he did - to keep the government from taking away the opportunity they were promised and returning them to the shadows.
