That was food and water fall under extraordinary treatment according to an evil Florida law, and by ruling Terri didn't want any extraordinary treatment if she was incapacitated, they make it difficult for any intervention.
Again, really evil.
How would ice chips on the tongue be anything but ordinary pallative care, though?
Actually, given that the law forbids the removal of pallative care, I can't quite figure how food and water, for someone who would otherwise suffer starvation/dehydration, would not be pallative?
