This is to allow the governor to step in on the side of survival if the adult's wishes are unclear (in a very specific context).In my example, the adult's wishes were unclear.
The husband claimed that lady's interpretation of Christian Science would not allow a brain drain.
The parents claimed that the lady's interpretation of Christian Science would allow a brain drain.
So the error if any ought to be on the side of preserving life.
When intentions are unclear or in doubt ALWAYS err on the side of life. ALWAYS ALWAYS ALWAYS!!!!
