With the JWs, 3 knuckleheads (er...I mean kind hearted elders who want to do Jehovah's will to keep the congregation clean) meet in secret in a back room and discuss the presumed guilt of the individual, and then come out and tell the congregation that such and such is no longer one of Jehovah's Witnesses.

Then they announce this to the congregation with no supporting information and expect everyone to shun this person. It is very secret and nobody knows if the person left on his own or was kicked out and for what reason.
How does this work with the LHMN? I know with Bible Student ecclesia that I know, there must be a church trial with everyone voting and this only after a Matthew 18.
