"but couldnt they announce that "_______ is no longer a Jehovahs witness" without any legal rammifications? isnt that why they stopped using "df'ed & da'ed"? so they can still fommand the cong to shun and not be sued?"
They could certainly try and possibly succeed. I'm not sure if these issues have been specifically addressed with Jehovah's Witnesses. They have won cases where that announcement came immediately after someone was disfellowshipped. The situation might be different for someone who can prove or at least claim that they have stopped being a Jehovah's Witness for a significant period of time. Yes the announcement would be true, but I don't think it would be hard to prove that it involves actual punishment since it is code for start shunning that person. In theory, there is a limited window of opportunity for the Watchtower Society to punish former members. I don't think the courts in the U.S. have had an opportunity to rule on this.
