It is a basic right of the accused to have a copy of a transcript in most courts, there are other basic rights that a JC by JW's denies, such as representation by a lawyer or "friend at Court" and pre-trial access to the evidence against the accused.
I would ask for a copy of their notes for preparing my appeal, I know this would be denied, but it makes them look what they are, a secret star-chamber kangaroo court where justice is virtually impossible.
Here in the U.K priest-penitent confidentiality is not enshrined in law, is it in the USA ? in which case, if it is, it is really incumbent upon the Elders to maintain confidentiality. (Not in the case of a confession of criminal behaviour, such as child abuse, I would think)
As to recording the proceedings, I would personally go ahead ,without telling them, and record their private deliberations. As to the latter, I would not splatter them all over the Internet, but the rest of the procedure I would, for the world to hear how un-christian this cult is.
I doubt they would take any action in law against you after the event, there are already some recordings on the Net of J.C's, they didn't do anything about those to my knowledge, but you/I would be taking a small chance, I suppose.
