The issues revolve around whether or not she was in a persistant vegetative state or not and whether or not, and whether or not she had a "living will".
She did not appear from films on TV to be a persistent vegetative state, nor was she permitted to be examined by physicians not under the control of her "husband", an adulterer.
There was no written document to prove any "living will" existed.
The actions and motives of her "husband" and open adulterer are suspicious and questionable.
The Judge in the Case, Greer, was apparently the recipient of campaign money from the firm representating Schiavo - or so it was so posted in this forum.
Whettemore (spelling?), the Federal Judge who reviewed the case, was from the Florida court system and was reviewing the actions of his collegues.
Congress passed a law directing the Federal Courts to review the case de novo - an action they blantantly and defiantely ignored.
