On Friday, BP attorneys argued that a three-judge panel of the 5th Circuit should overturn Barbier's approval order if the company's separate appeal of more recent rulings on settlement terms is unsuccessful. BP argues that Barbier misinterpreted the settlement and has allowed businesses to receive hundreds of millions of dollars for inflated or fictitious claims.
A different 5th Circuit panel heard the company's appeal in July but hasn't ruled yet. BP said it would still support Barbier's approval of the settlement if its appeal is successful.
Although Tuesday's brief doesn't explicitly address that dispute, plaintiffs' lawyers said BP initially was "thrilled" with how claims were being processed. They previously have argued that BP undervalued the settlement and underestimated how many claimants would qualify for payments.
Court-supervised claims administrator Patrick Juneau's office has made more than $4.5 billion in settlement offers to more than 55,000 Gulf Coast businesses and residents who claim the spill cost them money.
The private attorneys said only five groups of objectors have filed briefs with the 5th Circuit, while more than 200,000 claims have been filed with the settlement program. Only 731 of the 200,000 claims have resulted in appeals by class members, they added.
"For perspective purposes, over 69,000 business economic claims have been filed while only two lawyers, representing less than 15 businesses, have objected, voicing only the narrowest of a single concern," they wrote.
The 5th Circuit hasn't scheduled a hearing yet for objectors' appeals.
