This was just a procedural decision, NOT a decision on the substance of the matter (i.e. is DACA constitutional?). All that happened here is that the Supremes (well, 4 of them) decided NOT to go outside of normal judicial procedures, which are to have a District Court decision appealed to the Circuit Court, and only then to the Supremes. Nothing unusual about that at all - which doesn’t mean that I like this decision, but for some unknown reason they didn’t consult with me on it. :>)
I would be surprised if any of the nine voted to hear this case before the 9th Circuit has heard it. Certiorari before judgment is very rare, and I am not sure why it would be warranted in this case. It’s not like the government was in a rush to deport the DACA people even before there was a DACA.
