BP Plc asked a federal appeals court to block economic loss payments in its $9.2 billion settlement of the 2010 Gulf of Mexico oil spill unless they can be directly linked to the disaster. The London-based company said U.S. District Judge Carl Barbier in New Orleans has ignored the appellate court's earlier decision requiring him to review causation in determining which claims should be paid. The company asked an appeals panel for an immediate injunction.
