On Watchtower having a special relationship with congregations-
I don't want to contradict Robert's detailed report since I wasn't there, but I have read the briefs (and am an attorney), and the only special relationship issue raised in the briefs was whether WTS and/or the congregation had a special relationship with Candace Conti (and to a lesser degree Kendrick), and not with each other. Since parties are not allowed to raise new arguments that they do not address in the briefs, I wonder if this could have been a misunderstanding.
In this context "special relationship" has a legal meaning under California law, rather than a special relationship in the everyday meaning of the words. Generally no duty to warn or prevent harm from occurring to someone exists except in the case of one with a special relationship to the potential victim. This case did not involve agency or vicarious liability, where the WTS was held responsible for the elders' actions. Rather, the jury found 27% of the blame was with WTS for its own negligent actions.
