The Eleventh Circuit recently confirmed the rule that “other insurance” clauses should not be used to disadvantage policyholders. Nat’l Cas. Co. v. Georgia Sch. Bd. Ass’n - Risk Mgmt. Fund, No. 22-13779, 2023 WL 5977299, at *1 (11th Cir. Sept. 14, 2023). In a dispute between an insurance company and a public risk management fund, both insurance policies included “other insurance” clauses stating that each insurer would only provide excess insurance coverage where the policyholder is covered by other insurance. The district court found that the clauses were irreconcilable because both insurance policies could not provide only excess insurance coverage—at least one policy would need to provide primary coverage. Because of the conflict, the Georgia federal district court applied Georgia’s irreconcilable-clauses rule and held that each policy must provide coverage to the policyholder on a pro rata basis. The Eleventh Circuit affirmed the district court’s application of Georgia’s irreconcilable-clauses rule.

The California Supreme Court ruled that vertical exhaustion applied to determine how a policyholder could access its excess insurance policies. Montrose Chem. Corp. v. Superior Court, No. S244737 (Cal. Apr. 6, 2020). The case involved coverage for Montrose Chemical Corporation’s environmental liabilities at its Torrance facility under insurance policies issued from 1961 to 1985. Montrose and its insurers agreed that Montrose’s primary policies were exhausted but disputed the sequence in which Montrose could access the excess insurance policies.
