NEW ORLEANS - The stay of a Hurricane Katrina coverage lawsuit is still "unsettled" because federal courts have applied a Louisiana Supreme Court's key ruling on the issue of interruption of prescription "in disparate ways," a Louisiana federal judge ruled Aug. 14, denying the insurer's motion to sever the insureds' claims and proceed separately (Dewitt Lewis, et al. Hanover Insurance Company, No. 10-3026, E.D. La.; 2012 U.S. Dist. LEXIS 114059).
