NEW ORLEANS AP – A judge incorrectly dismissed several insurance companies from a lawsuit accusing insurers of overbilling the federal government for Hurricane Katrina’s flood damage in Louisiana, a federal appeals court has ruled.

Wednesday’s ruling by the 5th Circuit Court of Appeals in New Orleans only revives part of the case that lawyers for a group of purported “whistleblowers” filed against eight insurers and six adjusting firms after the August 2005 storm.
