NEW ORLEANS (AP) — A federal appeals court has opened the door for BP to appeal some claims related to a settlement reached after the 2010 Gulf of Mexico oil spill.

The appeals court in New Orleans late Friday ordered a lower court judge to change a procedure that effectively blocked appeals. And the appeals court told the judge to reconsider a rule barring BP from appeals regarding the calculation of a business' losses that are based on the way revenues and expenses are matched.

However, the appeals judges upheld a bar on appeals involving BP's contention that something other than the oil spill caused some losses. BP has already lost a series of court battles on its argument that settlement money was going to businesses that didn't have spill-related losses.
