NEW ORLEANS - An insured has failed to submit a timely signed and sworn proof of loss of her Hurricane Isaac damage and the National Flood Insurance Act (NFIA) does not authorize her extracontractual claims against her insurer, a Louisiana federal judge ruled June 3, dismissing the coverage lawsuit (Janina Howell-Douglas v. Fidelity National Indemnity Insurance Co., No. 13-5578, E.D. La.; 2014 U.S. Dist. LEXIS 75469).
