Yes, I did misunderstand that part you quoted, I apologise for that.
Your reasoning still proves nothing except what we already know, that neither the watchtower nor the parents are allowing blood transfusions, and they have no authority to prevent it from happening.
1) No, but I never claimed they did. (Hlc's draft these kind of legal documents, that's part of their work.)
2) No, and I never claimed they had.
All I do know is that the hlc's will follow guidance from the watchtower when they act, so either the watchtower allows the hlc's to draft these documents, or the hlc's keep it private and the watchtower is not informed or consulted.
Now I have questions for you:
Why are the parents asked to sign the document? Why do the hospital sign the document?
There has to be a benefit on the hospitals part,otherwise why would they make the concession? Is it so the parents do not cause trouble? Does coming to this understanding make things easier in any way for the hospital?
