I was envolved about 16 years ago in a committee that sole purpose was to disfellowship a respected member of the congregation for being an apostate. We recieved information from the WT legal department and CO and DO on how to proceed. Often the CO and DO would meet with us individually to sort of direct the process.
We couldn't get the brother df'd for apostacy so the legal made up 2 questions we were to ask the person and if they answered anything other than a "Unqualified Yes" to these questions then we were to announce under strict wording from the legal department that:
"So and so was no longer one of Jehovah's Witnesses" we were told by the legal department,, that we were not to answer any questions the friends might ask us about the announcement.
