Maybe they are approaching this case from the wrong standpoint. Florida laws, if I understand them correctly, allow that a non-terminally ill patient, who may or may not be in a persistent vegetative condition, can be starved to death. The law also allows that nourishment and water fall under the definition of medicine or artificial life support. That may be unconstitutional and someone should look into appealing those laws to the Supreme Court.
The judge is bound to follow the law as it is written, whether or not it is moral, although mandating the death penalty to anyone based on hearsay testimony from one who has a "clear and convincing" conflict of interest and "remembered" his wife's wishes years later is highly questionable.
Even if a person is truly in a persistent vegetative state, it should be illegal to starve them to death in all 50 states. That's the can of worms they seem to want to keep the lid on.
This law is in many states. I believe it's in place in Va.
That's where Hugh Finn was starved.
His case is very simular to Terri's
