The administrator of the Deepwater Horizon oil spill settlement fund has denied BP PLC’s latest allegations of potential fraud among members of an appeals panel that reviews claims and involving an employee in a customer center in Alabama.

BP has moved for the third time to halt the processing of payments to individuals and businesses with economic damages claims under the settlement, the value of which it revised last month to $9.6 billion. U.S. District Judge Carl Barbier, overseeing the oil spill litigation in New Orleans, has twice denied similar requests by BP.
