Responding to certified questions from the Fifth Circuit, the Texas Supreme Court held that in limited circumstances, extrinsic evidence may be considered in determining the duty to defend. Monroe Guar. Ins. Co. v. Bitco Gen. Ins. Corp., 2022 Tex. LEXIS 148 (Tex. Feb. 11, 2022).
The two insurers each provided CGL coverage to the insured, 5D Drilling & Pump Service, Inc., at different times. BIitco provided two consecutive one-year CGL policies covering October 2013 to October 2015. Monroe's CGL policy covered 5D from October 2015 to October 2016.
5D was sued by David Jones for breach of contract and negligence, seeking damage allegedly resulting from 5D's drilling operations on Jones's property. Jones contracted with 5D in the summer of 2014 to drill a 3600-foot irrigation well on his farmland. The complaint did not detail when 5D's purportedly negligent acts occurred or even when 5D began or stopped the work.
5D demanded a defense from both insurers. Bitco defended under a reservation of rights, but Monroe refused to defend, contending that any property damage occurred before its policy period began. Bitcon sued Monroe in federal district court, seeking a declaration that Monroe owed a defense to 5D. Bitco and Monroe stipulated that 5D's drill bit stuck in the bore hole during 5D's drilling "in or around November 2014," or about ten months before Bitco's policy would end and Monre's would begin. Both parties sought summary judgment on the issue of whether Monroe owed a duty to defend.
The federal district court applied the eight-corners rule and concluded Monroe owed a duty to defend. Monroe appealed. The Fifth Circuit certified questions to the Texas Supreme Curt asking whether consideration of extrinsic evidence was permissible as articulated in Northfield Ins. Co. v. Loving Home Care, Inc., 363 F.3d 523 (5th Cir. 2004). Northfield predicted the Texas Supreme Court would recognise an exception to the eight-corners rule and apply it only "when it is initially impossible to discern whether coverage is potentially implicated and when the extrinsic evidence goes solely to a fundamental issue of coverage which does not overlap with the merits of or engage the truth or falsity of any facts alleged in the underlying case." Id. at 531.
The Texas Supreme Court adopted the Northfield standard. If the underlying petition stated a claim that could trigger the duty to defend, and the application of the eight-corners rule, due to a gap in the plaintiff's pleading, was not determinative of whether coverage existed, Texas law permitted consideration of extrinsic evidence provided the evidence (1) went solely to an issue of coverage and did not overlap with the merits of liability, (2) did not contradict facts alleged in the pleading, and (3) conclusively established the coverage fact to be proved.
The second certified question ask whether, when applying the exception, could the court consider extrinsic evidence of the date of an occurrence? The court answered yes, so long as the extrinsic evidence met the other requirements set forth by the court. Here, however, the extrinsic evidence did not pass the test. Evidence of the date of property damage overlapped with the merits. A dispute as to when property damage occurred also implicated whether property damage occurred on that date, forcing the insured to confess damages at a particular date to invoke coverage, when its position could very well be that no damage was sustained at all. Because the use of the stipulation would overlap with the merits of liability, it could not be considered in determining whether Monroe owed a duty to defend.
