You mention that Ackman has no case before the court, which is true. He did, however, file suit against the gov. in 2014 claiming that they illegally confiscated GSE profits.
He initially voluntarily dropped one suit and later the second I believe. What role do you see him playing in this settlement and why do you think that he dropped his suits? Could it be that he is working with other litigants, funding their suits, etc.? Perhaps this is a better strategy to have access to different courts/judges. I don't see him just idly standing by without strategic involvement.
As for warrants, what is your opinion on whether or not they are exercised in some fashion based on your knowledge of the situation?
