Large, you bring up some interesting points, but I don't think it's as simple as you're making it out to be.
First and foremost, if the hedgies are found to have engaged in insider trading, the judge would most certainly change the contract rate to the federal judgment rate. This alone would waterfall into the preferred pool.
Secondly, you are failing to note that the hedgies are not only the debtors, but they make up some of the creditor class as well. Because of that, if insider trading is found, there is absolutely no way the judge could consider the GSA "fair and reasonable". This, in addition to the fact that insider trading would have automatically indicated "bad faith negotiations".
Going after the hedge funds is a genius move by Susman. I only wish we had done so sooner.
