Correction, 3/2/2014, 8:00 a.m. EST: An earlier version of this article incorrectly stated that BP tried to decertify the class of plaintiffs covered by the settlement of economic and property damages claims. Instead, the company has argued that if the district court continues to reject BP’s position on the settlement terms, then the class must be decertified.

Update: On March 3, the U.S. Court of Appeals for the Fifth Circuit rejected BP’s appeal of the causation issue.
