Case Brief Summary & Legal Analysis

General Brief
4 min read

tl;dr: Policyholders whose properties were flooded after Hurricane Katrina-related levee breaches sued their insurers. The court held that the policies’ standard “flood” exclusions were unambiguous and barred recovery, even if third-party negligence in maintaining the levees caused the inundation.

Legal Significance: A standard “flood” exclusion in an insurance contract is unambiguous and applies to inundations from man-made structure failures, not just “natural” events. The underlying cause of the failure, such as negligence, is irrelevant to the application of the clear and explicit contractual exclusion.

Case Facts & Court Holding

Key Facts & Case Background

In the aftermath of Hurricane Katrina, levees along three major canals in New Orleans ruptured, causing catastrophic flooding. Numerous homeowners, renters, and commercial property owners (plaintiffs) with all-risk insurance policies sought coverage for their water damage from their insurers (defendants). The policies contained exclusions for loss caused by “flood.” The plaintiffs argued that their losses were not caused by a “flood” in the natural sense, but rather by water intrusion resulting from the negligent design, construction, and maintenance of the man-made levees. They contended that because the term “flood” was undefined in the policies and did not explicitly exclude man-made or negligence-induced events, it was ambiguous. Under the principle of contra proferentem, they argued this ambiguity must be construed in their favor to provide coverage. The insurers moved to dismiss, asserting that the inundation of water was unambiguously a “flood” under the plain meaning of the policy exclusions, regardless of the cause of the levee failures. The district court found the term ambiguous for most policies, but the Fifth Circuit granted an interlocutory appeal to resolve this controlling question of law.
