There was not a Supreme Court case, but the SOFA allowed such votes to stand in June, and no one even challenged it to the Court as there was a pretty wide spread consensus that this was the right decision (at least in public statements, perhaps some people opposed these votes being counted but didn't want to publically state their views).
Public opinion is irrelevant, the reason it wasnt challenged was because it wouldnt have affected the outcome of the election.
This may be very well true, and I would have understood very well if the supreme court had ruled Hawk's vote invalid.
But the SOFA should have stuck to his own precedent.
Not that it matters now, this thing is over, and I'd like to congratulate WMS on his victory.
