Judge Greer has declared, based on the statements of Schiavo and two siblings of his, that Terri said she did not want to live as a vegetable. Such statements are contradicted by her family, who also note that she feared Schiavo would try to kill her. They are also contradicted by Schiavo's own statements at the trial where he received over $1M in insurance payouts.
To claim in an malpractice suit that one is going to learn nursing skills to take care of one's wife, and immediately upon receiving the money declare they she said she'd have wanted to die in such a situation seems rather suspicious, does it not?
Further, even if Terri had indicated that she'd want to die if in a permanent vegetative state, there are supposed to be certain protocols to determine whether someone is, in fact, in such a state. If therapies are attempted and prove ineffective, then someones wishes to die if in a permanent vegetative state might come into play. In the extant case, however, Judge Greer is accepting the word of a hired "expert witness" who says he believes Terri is in a permanent vegetative state even though he's not done the protocols necessary to prove it; further, he ignores affidavits from other doctors who state that Terri's behavior is grossly inconcistent with her being in a permanent vegetative state.
