I think you are missing the target. You would need to file a civil lawsuit directly against DW. Then all you need to show is he was not acting in the best interest of the majority of the members (his charter) thereby he is acting on his own. Then ALPA would not bear liability for his actions and he would have to fund the suit himself. Don't know how that really helps but it would feel better.

Also, How about under the Federal RICO statutes showing that DW conspired with JL to defraud those affected. If you could show that they had reason to act in that manner for personal gain (does not have to be monetary, could be increased power) then the fact that other also benefited is not relevant. Much broader net under federal statues but you'd need a prosecutor buy into that theory.

Isn't this fun.
