The chapter 11 protection of Texas's largest power company, Energy Future Holdings, will remain with the U.S. Bankruptcy Court for the District of Delaware, the judge handling the case ruled on Thursday, Reuters reported on Friday. Energy Future filed one of the largest nonfinancial bankruptcies ever in April in Delaware, where the company's subsidiaries are incorporated. The company has $42 billion in debt. U.S. Bankruptcy Judge Christopher Sontchi rejected arguments by a trustee for junior creditors that the case should be in Dallas, where the company is headquartered, because it would better serve employees and regulators.
