Given the SCOFLAw's bravura performances, that's not a bad way to bet, but whether the SCOTUS backs that up is another story. The ghouls who want her death are predicting a quick injunction on Monday, which sounds farfetched since the results would be irreparable harm to Terri.
I don't see that happening at all. There is absolutely no reason to rush to an early decision in this matter, for exactly the reason you mention.
I read somewhere else this morning that the Florida AG will file his brief defending the law by next Friday, which sounds far more realistic.
