I believe that we have seen this story before. i said at the time that I thought that the hospital were "trying it on", albeit in a laudable attempt to save her life.
"Her emotional husband told the court his wife had signed a document used by Jehovah's Witnesses, known as the Advanced Care Directive, "
If she signed the standard form then it was illogical that she would amend it in the way they say. She would either stand by it, or say to do anything.
I am glad if she gets better, but if one believes in an adult patients freedom to choose or refuse what happens to their body , it is not a good thing for personal liberty
