Sounds like GM is about to have some problems. A judge is looking into the possibility that when GM took a buyout from the government in 2009 and had the company restructured, that a huge chunk of the money was purposely diverted to hedge fund holders. This was done without many people knowing, and also at the expense of other creditors. If the judge decides that this was improper, he could open up the lawsuit which could wind up costing GM close to a BILLION dollars. Hit the link after the jump.
