There are two courts of law talked about here. To make sense of it all, you have to separate them. There are the bible laws and the secular laws. First, about secular law. In the US there is a definite separation of church and state. Typically, the courts will not get involved in the internal workings of a church. We could start a church of "Stand on your head and Whistle Dixie and when you fall over you are OUT." and the courts would not intervene. No laws broken there.
There is the whole matter of the civil courts, however, if you feel that someone has caused you harm. Again, the courts would likely not intervene because the principle of "buyer beware" is involved. You were informed of the rules of the club going in, so too bad for you. As has been described here, however, if the organization itself breaks its own written rules, you may have a chance to sue for damages. In that case, name the individuals who broke the rules and hold them personally responsible, as well as the organization itself because they are the ones who recruited the miscreants, and they are the ones with the deep pockets. Why didn't the organization keep the elders in check?
As for the bible laws, who do you appeal to if they are broken? Jehovah, of course. In my opinion, this is one of the fundamental flaws of this organization. There are no human-led checks and balances that we see in secular government, and in many churches. In many churches, and incompetent pastor can be voted out, his contract expires. In secular government, the President gets four years to prove himself. The Watchtower Society shows remarkable inflexibility. I believe this is because once in a position of power, it is well-nigh impossible to budge a Governing Body member until death. Old geezers are not very sympathetic of the problems of youth. And how JW youth suffer!
