Sorry, the old memory is not what it was, so I won't attempt to guess a year, I remember the Letter coming, and on a subsequent C.O visit, he read it and emphasized how important it was.
Important to the Org that is, as the motivation behind it was to make sure that no Elder implicated the Org in any way, they did not wish to be in Court as an Org, and even less did they wish to pay compensation.
This effectively left Elders out in the cold, and highlighted the greedy money-grubbing attitude of the Org, and its total lack of love or concern for the victims. Things have not changed.
The G.B and leaders of the J.W Org are heartless avaricious BASTARDS !
