The Fifth Circuit has upheld the multibillion settlement of the claims of the residents and businesses impacted by BP's oil spill in the Gulf of Mexico, The Washington Post reports. BP had objected to the approval of the settlement by arguing "that U.S. District Judge Carl Barbier and court-appointed claims administrator Patrick Juneau have misinterpreted settlement terms in ways that would force the London-based oil giant to pay for billions of dollars in inflated or bogus claims by businesses," The Post further reports. BP argued that the class of claimants could have included people who didn't actually suffer any injury due to the oil spill.
