BP will be asking a federal judge in New Orleans today to approve refunding some settlement payments over the 2010 oil spill.
The company says hundreds of millions of dollars should be returned from some businesses that received payments between August 2012 to October of last year.
BP says it's fair because Judge Carl Barbier found the formula used at that time was incorrect, and ordered a change.
Opposing attorneys say BP is trying to get out of its obligations. They say the release plaintiffs sign to get a settlement payment is a binding agreement for both sides.
Barbier has given each side 20 minutes at a hearing today.
He's also hearing arguments about whether cleanup workers can be paid under the settlement for chronic medical problems blamed on the spill but not diagnosed until after April 16, 2012.
