If the issue gets kicked upstairs to the SCOTUS it could buy enough time.
Here's what I see as the perfect case scenario: investigation into allegations of the HINO get him removed as Terri's guardian. Meanwhile, while the battle against Terri's Law and the Constitution is being fought in the courts, an order is issued that would require Terri to be allowed whatever therapy might be available. (Don't you think that there might be neurologists and others who would DONATE time to this now?)
Anyway, Terri responds to treatment and rehabilitation, new tapes are made (unfettered by HINO) which prove to the world that 1) Terri was NOT vegetative, 2) HINO is a pathological liar and 3) the courts were dead wrong. Seeing this in the new light sways the court to make the right decision and uphold life and the Constitution so that this doesn't happen again, to Terri or anybody. If, in the course of the investigation, George Felos was exposed for the charlatan he is, that would be icing on the cake.
And finally, investigation of the HINO uncovers enough to bring him up on criminal charges and we pop the popcorn and watch the perp walk. It would be a really nice touch if we had a shot of Terri watching the perp walk from her wheel chair as well, and laughing out loud!
Well I DID say this would be the ideal! *Sigh*
