When can courts consider extrinsic evidence in insurance duty to defend cases? Equine Assisted v. Carolina Casualty Explained

The Utah Supreme Court’s decision in Equine Assisted Growth and Learning Association v. Carolina Casualty Insurance Company clarifies when courts may consider extrinsic evidence in determining an insurer’s duty to defend under an insurance policy.

Background and Facts

After EAGALA terminated Greg Kersten as CEO, he filed an unauthorized lawsuit against EAGALA’s board, deceptively captioning the complaint to make it appear that EAGALA was the plaintiff. Though Kersten lacked authority to sue on EAGALA’s behalf, he obtained a temporary restraining order. EAGALA incurred substantial defense costs before ultimately dissolving the order. When EAGALA sought coverage from Carolina Casualty, the insurer denied the claim under an “insured versus insured” exclusion that excluded claims brought “by, on behalf of, or in the right of” EAGALA.

Key Legal Issues

The central issue was whether courts must limit their duty to defend analysis to the “eight corners” of the insurance policy and complaint, or whether they may consider extrinsic evidence when policy language requires determining facts not apparent from the complaint’s face.

Court’s Analysis and Holding

The Utah Supreme Court held that the duty to defend analysis depends on the policy’s contractual terms. When policy language conditions coverage on allegations contained in the complaint, courts apply the traditional “eight corners” rule and exclude extrinsic evidence. However, when the policy conditions the duty to defend on objective facts not determinable from the complaint alone—such as whether a claim was actually brought “by, on behalf of, or in the right of” the insured—courts must consider extrinsic evidence to resolve the coverage question.

Practice Implications

This decision emphasizes the importance of carefully analyzing insurance policy language when challenging coverage denials. Practitioners should examine whether policy exclusions or coverage provisions depend on factual determinations that extend beyond the complaint’s allegations. When they do, courts will consider extrinsic evidence, creating opportunities to challenge insurers’ coverage positions through factual development rather than being limited to purely legal arguments based on the pleadings.
