There's a level of review (sort of) between the Supreme Court and the 9th Circuit.
It's called an en banc review and is basically a request for the entire federal appeals court to decide the issue instead of just a three-judge panel of the court.
(Disclaimer/clarification - My understanding is that the Ninth Circuit, unlike other circuits, has so many judges (30+) that a review by *all* of the justices is nearly impossible because of the size the courtroom would have to be. But they still do en banc reviews).
Anyhow, it will most likely be overturned en banc and the Supreme Court will deny cert (refuse to hear the case - leaving the last ruling in effect).
