BP Plc and Anadarko Petroleum Corp narrowly failed to persuade a U.S appeals court to reconsider its 2014 ruling that they could face civil fines under federal pollution laws over the 2010 Gulf of Mexico oil spill. By a 7-6 vote, the 5th U.S. Circuit Court of Appeals let stand a three-judge panel's decision to uphold a 2012 ruling from U.S. District Judge Carl Barbier in New Orleans, in which he said the companies could face Clean Water Act penalties.
