A FEDERAL JUDGE on Thursday refused to allow a class action against State Farm Insurance Cos. over the insurer’s denial of claims on Mississippi’s Gulf Coast after Hurricane Katrina.

State Farm policyholder Judy Guice had asked U.S. District Judge L.T. Senter Jr. to permit her to join other policyholders whose homes were reduced to slabs by the August 2005 storm in a class action against the Bloomington, Ill.-based insurer.
