None of the doctors on whose judgment the court relied ever saw Terri Schiavo. None. They examined brain scans and other diagnostic materials which did not add up to a full clinical diagnosis, because they did not involve personal contact with or observation of the patient.
Repeated appeals and reviews resulted in the same conclusions because they were merely reiterating the same opinions on the same brain scans. At no time did they admit other, more relevant diagnostic criteria.
Moreover--- and this is actually the most important point--- Terri's brain scans and her measurable responsiveness, or awareness, or lack thereof, don't actually matter from a moral or legal standpoint: because it is morally wrong, a medical ethical violation, and, in the State of Florida, a specific crime under law, to intentionally deprive a dependent person of food or water, no matter what the person's level of disability.
Michael Schiavo's role as his wife's medical proxy/guardian ought to have been terminated when:
I don't know whether claims made about Terri's husband by Terri's parents were out of line, and if they lied, that's libel. Michael Schiavo himself never, to my knowledge, charged them with libel, so that's not directly relevant to the present discussion.
Putting that to the side, Terri's mother's and father's intentions to secure basic, decent ordinary care (food and water) and prevent their daughter's premature death are not bias; they demonstrate the only legitimate attitude of medical guardianship.

Thank you for that reply. You provided an excellent summary of a case that should have never unfolded the way it did.
There is absolutely no reason that Terri should not be alive and happy in her family’s care today.
