The last congo I was in, we had a wealthy elder who would absolutely refuse to sit on any judical committee if the the accused appeared savvy enough to think to call a lawyer.
He cited the WTS' letter to bodies of elders in which they basically said, if sued you're on your own. He said he would be an obvious target of such a lawsuit because he had been very successful in business and was visibly well off. His position was the Society, by its letter, had made it necessary for him to make choices when it came to volunteering to sit on JCs. The other elders just shrugged and moved on with the discussion, finally settling on elders with less to lose.
