Reading that passage it seems to me that Robson argues that he needs to keep in the Corporate Defendants to be able to do discovery on them which he "believes" would lead to him being able to identify other individuals as direct perpetrators of transporting him for the purpose of lewd acts. Seems to be yet another desperate fishing attempt to me.
Who will he sue? Employees working for those companies? Does he look for dirt on Weitzman and Branca? I wonder if that crazy FBI files article made them believe (or at least desperately hoping) that there was really some big cover up and child abuse maffia going on around MJ with Weitzman and Branca involved?
BTW, this is from a prosecution motion from 2005:
So Joy Robson was pushing MJ for the green cards and to bring them to the US. So why doesn't Wade sue his mother on Penal Code 266j?
