SCOTUS is one of the very few courts that controls its own docket so is free to decide, with or without giving a reason, what cases it will hear on the merits. Over 95% of the applications to SCOTUS are rejected without giving a reason exactly as happened here, so the disposition of this case without a reason is not in the least unusual. (Yes, I am a lawyer).
SCROTU denied the stay. I’m probably grasping at straws but does that imply other aspects of the case are still under consideration or was that part and parcel of the whole case?
