As you know darkspilver - standard jw procedure when there is an appeal committee is to have the original committee sat in the same room.
Procedure AFAIK is -
Local Elders initiate contact to CO - "We have a decision appealed."
CO - "I'll send three brothers."
Bigger cases.
CO to Branch "Got a tough one here boys whad'll I do?"
Branch - "We'll sort it and arrange a "Special Committee."
In either case the original elders initiate contact up the food chain.
