Fisker Automotive Inc.'s creditors pounced Tuesday to preserve potential lawsuits targeting the U.S. Department of Energy's decision to shut off funding to the hybrid-car maker, Dow Jones Daily Bankruptcy Review reported today. The move came as Fisker sought preliminary court approval to tap a bankruptcy loan and move toward a sale of its operations to Hybrid Tech Group LLC. Bankruptcy Judge Kevin Gross cleared the bankruptcy financing on an interim basis and set a Jan. 3 hearing date to review the sale of Fisker to Hybrid Tech. However, the judge said he will hear from an official committee of unsecured creditors once that panel is formed before making any final decisions.
