Back in September, a federal district judge in Oklahoma, agreeing with a three-judge panel opinion of the D.C. Circuit, held that the Affordable Care Act subsidies applied only to states that had, themselves, established state exchanges and not states in which the federal government had to run the exchange after the state refused.
Well, a lot has happened since then. The D.C. Circuit took its case up en banc, vacating the panel opinion, and the U.S. Supreme Court agreed to hear the challenge in the form of King v. Burwell, a Fourth Circuit case finding the other way.
Now, Oklahoma's attorney general wants to appeal his state's case straight to the Supreme Court.
