Allocating defense costs among insurers

In Continental Casualty v. North American Capacity Ins. Co., the district court required three primary carriers to split defense costs, while not allowing the excess insurer to recover defense costs from the primaries.  No. 10-20262 (May 30, 2012).  The Fifth Circuit affirmed on the cost-splitting issue, after careful review of the policies’ coverage triggers, scope, and “other insurance” clauses.  Op. at 15-20.  The Court reversed as to the excess carrier, finding it had a right of contractual subrogation, and distinguishing Mid-Continent Insurance v. Liberty Mutual, 236 S.W.3d 765 (Tex. 2007).
