NS7, you ask good questions, that at least to me, don't have obvious answers.
The only thing that I can think of quickly, is that they either have some specific information or evidence only pertaining to Healthnet, or they think that if they make an example of Healthnet that all the others will follow obeying the dictates of the verdict. But those are just guesses. I assume Amarin has the exact the answers to your questions.
