So reports Lyle Denniston.

One potentially likely outcome is this: the Court decides to summarily reverse, and at least Justices Ginsburg and Breyer write a dissent from the summary affirmance (here’s why).  Justice Scalia (or another Justice) decides to issue a statement concurring in the summary reversal.

If all of this happens, the Court’s term will likely end with no mention of the Montana case, because, with the crush of end-of-the-term opinions (including the high profile health care cases), these opinions won’t be written in time for the end of the term.
