I simply want to add that I support her comment. She is not exaggerating when she says that it would cost that much. However, I am also a practising lawyer, and my opinion is that this would only be at first instance. Preparing a case for Superior Court can easily cost a half million dollars. Then there is the appeal, and then the appeal before the Supreme Court.
Moreover, each appeal level always involves more interveners in the issues. I think this is a good thing, and I am not saying that to criticize the interveners, but it also increases court case costs. Indeed, every intervener has a written argument that is submitted to the court. We must answer all of the arguments from all of the interveners, and not only the arguments of the opposite side.
In my opinion, a half million dollars is thus a normal amount, but only in first instance proceedings.
