BP estimated more than a year ago that it would spend roughly $7.8 billion to resolve tens of thousands of claims by businesses and individuals covered by the settlement. The company now says it can't give a reliable estimate for the total value of the deal.
Barbier also heard testimony earlier this year for a first phase of a trial designed to identify the causes of BP's April 2010 well blowout and assign percentages of fault to the companies involved.
Billions more hinge on the outcome of the trial, which includes claims by the federal government and Gulf states. It's unclear whether Barbier will issue any substantive rulings before the trial's second phase, which is scheduled to start in the fall.
The spill began in April 2010 after the BP-leased drilling rig Deepwater Horizon exploded off the Louisiana coast, killing 11 rig workers. Roughly 200 million gallons of crude oil were released from the Macondo well a mile under the Gulf surface. Marshes, fisheries and beaches from Louisiana to Florida were fouled by the oil until a cap was placed over the blown-out well in July 2010.
BP set up a compensation fund for individuals and businesses affected by the spill and committed $20 billion. The claims fund initially was handled by lawyer Kenneth Feinberg but Juneau took over the processing of claims after the settlement was reached last year.
Juneau's office announced in May that it has determined more than $3 billion in claims are eligible for payment through the settlement agreement. More than 162,000 claims were filed and more than $2 billion had been paid to claimants as of May 6.
