To add to what DoubtingBro already expressed -
When pressed by courts and lawyers the WT will claim that they cannot reveal anything about what transpires in a judicial meeting citing that it is protected under clergy confidentiality. There is even a statement provided in the book for elders to read verbatim when the accused tries to have legal representation in a JC.
This defense has already been denied by the courts for a few reasons including the fact that the JC is already in the practice of sharing confidential information with other outside parties, even without the knowledge of the accused. As a matter of fact, the new elders book says that when advice or other opinions are needed a JC committee may engage other parties (experienced elders, CO's, the branch) with confidential information regarding the accused. It further outlines that when such actions are taken the elders are not to tell the accused they are consulting with others.
