On June 9, the U.S. Supreme Court said BP must continue to pay claims as it pursues legal challenges to the payouts.
Friday's filing came six months Barbier directed Juneau to change his policy in reviewing claims applications, and ensure that claimants be able to "match" revenues with costs for the purpose of calculating financial losses.
BP said Juneau's new policy, which won court approval on May 5, will lead to "dramatically different calculations of lost profits," and justifies recouping earlier, inflated awards.
To illustrate the potential changes, BP said a seller of animal skins would have under the new policy been paid $14 million less than it was awarded, while a construction company located hundreds of miles from the Gulf would have been paid $8.4 million less.
Juneau's earlier interpretation "resulted in claimants receiving awards well in excess of what they are entitled to under the settlement agreement - in some cases by millions of dollars - or awards that weren't warranted at all," BP spokesman Geoff Morrell said. "Letting these erroneous awards stand uncorrected would violate basic principles of fairness and equity."
Steve Herman and Jim Roy, the lead lawyers for business claimants, said in a statement: "This is just another attempt by BP to back out of the commitment it made to the Gulf."
A spokesman for Juneau did not immediately respond to a request for comment.
The April 20, 2010 explosion of the Deepwater Horizon drilling rig and rupture of BP's Macondo oil well led to 11 deaths and the largest U.S. offshore oil spill. BP has said it has taken $42.7 billion of pretax charges for the spill.
The case is In re: Oil Spill by the Oil Rig "Deepwater Horizon" in the Gulf of Mexico, on April 20, 2010, U.S. District Court, Eastern District of Louisiana, No. 10-md-02179.
