I don't believe this would be possible today considering the GB knows the tremendous impact Ray Franz did to their movement. They probably have all higher ups (branch coordinators, bethel elders, committee members, and GB) sign a non-disclosure agreement or confidentiality agreement and extend this 50 years AFTER they leave if they are ever terminated, suspended, disfellowshipped, or made to resign.
There are however, certain limitations in various country statutes that can make null or void depending on circumstances.
That's my 2-cents. :-)
