For decades, an insurer’s duty to defend under Texas law was determined exclusively by reviewing the insurance contract and the allegations of the complaint under the “eight-corners rule.” All of this changed last week when, in a long-awaited decision, the Texas Supreme Court ruled that courts may consider extrinsic evidence to determine the existence of coverage in certain limited situations. Monroe Guar. Ins. Co. v. BITCO Gen. Ins. Corp., No. 21-0232, 2022 WL 413940 (Tex. Feb. 11, 2022).

In Monroe, a drilling contractor was sued for damages arising out of the allegedly botched drilling of an irrigation well. The underlying lawsuit alleged that negligent drilling caused damage to surrounding farmland. However, the complaint did not allege when the damage occurred. The contractor’s insurers, BITCO General Insurance Corporation (“Bitco”) and Monroe Guarantee Insurance Company (“Monroe”) disputed whether Monroe owed a duty to defend. Although Bitco agreed to provide a defense, Monroe refused, arguing that the property damage happened before its policy period. Bitco sued Monroe for contribution. In the trial court, the insurers stipulated that a drill bit became stuck before Monroe’s policy incepted, a fact that would have supported Monroe’s “prior damage” defense. On summary judgment, though, the trial court ruled this stipulated fact could not be considered under Texas’ eight-corners rule. Monroe appealed, and the Fifth Circuit, which had previously endorsed an exception to the eight-corners rule under Northfield Insurance Co. v. Loving Home Care, Inc., 363 F.3d 523, 531 (5th Cir. 2004), certified the question to the Texas Supreme Court.
