This is a tough one and I don't envy any of the judges who have to rule on it.
On one side is the husband who they suspect had something to do with the condition she's in. He wants to get remarried so he has something to gain by her death.
On the other hand, I know that I personally would not want to be in the physical/mental state that she's in even if it's not technically vegetative.
What I don't understand is why the husband won't relinquish legal care to her parents in exchange for a divorce.
