"In fact, Defender of Truth having all of your pointed references too, claims that he does not know either."
Maybe because I misunderstood your vaguely worded questions..
1. Do you know for a fact that Watchtower drafted any part of the Letter of Understanding posted on this thread?
2. Do you know for a fact that Watchtower (appointees) asks for the LOU posted on this thread in connection with medical treatment?
First question was ridiculous, since when has it been claimed that the Watchtower society drafted this letter?
Second question, I thought you meant do the Hlc request this letter from the Watchtower, which has not been stated anywhere as far as I have seen.
If in the first question you meant Watchtower appointed men, my reply would be yes.
If in the second question you meant do they ask the hospital whether the lou is in place, my reply is yes. Marvin has cleared it up now, it seems.
