And a court has found that Terri Schiavo does not want extra ordinary measures used to preserve her life and that she has that right.
Until that ruling is overturned, if Jeb does act outside the scope of his authority, he will be violating Terri Schiavo's rights.
What a court finds is not the measure of one's rights. Real rights are inalienable, a court decision cannot strip a person of them. In the specific case, the court's finding is of course an abomination that should offend anyone even reasonably familiar with the facts of the case. The court made the finding in contravention of law - hearsay evidence is not admissible in court, yet that's all the court's findings of Terri's alleged will is based on.
Oh... furthermore, food and water are not extraordinary measures. There's nothing that she requires to stay alive that you and I do not also require.
And your point is what, exactly? German courts found that Jews could be deprived of their property. Many US courts have 'found' innocent people guilty. Just because the courts 'find' something doesn't mean it is correct.
I'm beginning to think the judiciary couldn't find its own posterior with both hands glued to it, but that's just me.
