Forgive my ignorance for this question as I am a scientist and not a scholar on governmental or legal topics:
Where do judges and the court system come into play here?
Where does legislation come into play here?
What needs to happen in order for someone with some power to finally put their foot down and say "This will end now"? And if that ever does happen, who gives the say so? The head of DHS? The President? A ruling by the supreme court?
My understanding is that the court would only get involved if/when it comes down to a lawsuit...is this correct?
