BP PLC has petitioned an en banc panel of a federal appeals court to rehear a three-judge panel’s recent decision upholding the fairness of the Deepwater Horizon oil spill settlement.

In moving for a rehearing by the full court, BP continued to challenge what it calls the “causation” issue—certification of a class that includes claimants asserting damages not caused directly by the 2010 spill. BP has maintained that the settlement administrator’s interpretations and court orders involving the deal have resulted in awards to individuals and businesses with no oil spill damages.
