NEW ORLEANS - An insurer has a duty to defend some underlying claims arising from construction defects in an insured's demolition and renovation work on a restaurant, although the insurer has no duty to defend and indemnify underlying claims regarding costs incurred in the business interruption, a Louisiana federal judge held March 5 (Mark A. Morad v. Lino J. Aviz, et al., No. 12-2188, E.D. La.; 2014 U.S. Dist. LEXIS 28189).
