FILE - In this Sunday, June 6, 2010 file photo, a small oil-covered fish floats on the water's surface at Bay Long off the coast of Louisiana following a deadly April 20, 2010 explosion at the BP Deepwater Horizon offshore platform. The subsequent leak released an estimated 172 million gallons of petroleum into the Gulf of Mexico. BP argued Wednesday, Sept. 24, 2014, in New Orleans, that a flawed funding formula in the settlement is giving money to businesses for questionable claims, and they should be forced to return it. But U.S. District Judge Carl Barbier says a deal is a deal. His ruling thwarts BP's latest attempt to control its soaring liability from the spill, which may be nearing $50 billion.
