NEW ORLEANS - An insurer cannot demonstrate that arbitration claims regarding construction defects are unambiguously excluded from coverage, a Louisiana federal judge held April 9, denying summary judgment to the insurer regarding its duty to defend and finding that a ruling on the duty to indemnify issue is premature (Travelers Casualty and Surety Company of America v. University Facilities Inc., et al., No. 10-1682, E.D. La.; 2012 U.S. Dist. LEXIS 49970).
