NEW ORLEANS AP – Citing ethical breaches, a federal judge Friday barred a group of Mississippi attorneys once affiliated with a well-known tort lawyer from representing any policyholders in lawsuits against State Farm Fire and Casualty Co. over Hurricane Katrina damage.

U.S. District Judge L.T. Senter Jr. in Gulfport, Miss., also disqualified two key witnesses in the lawyers’ cases from testifying against State Farm or their former employer, a firm that helped the Bloomington, Ill.-based insurer adjust Katrina claims.
