This week, Corzine's lawyers are seeking to have a civil case dismissed. A group of investors, including the Virginia Retirement System, claim Corzine, MF Global and its banks — including Goldman, JPMorgan Chase and Citigroup — misled investors about the risks MF Global was taking with its leveraged bets on European debt. Corzine's lawyers claim the case "makes no sense" because Corzine bought 50,000 shares of MF Global two months before the collapse, The WSJ reports. Furthermore, Corzine's lawyers say the firm collapsed because of "unsuccessful business strategies," not fraud.
