Ohio Casualty Insurance v. Unigard Insurance

Citations: 564 F.3d 1192; 2009 U.S. App. LEXIS 11104; 2009 WL 1160297Docket: No. 08-4003

Court: Court of Appeals for the Tenth Circuit; April 28, 2009; Federal Appellate Court

Narrative Opinion Summary

In a declaratory judgment action, Ohio Casualty Insurance Company sought to clarify the responsibility to defend the Cloud Nine defendants in a lawsuit initiated by EdiZone, L.C. The case involved allegations of patent infringement and other business torts. Ohio Casualty provided coverage from 2001 to 2002, while Unigard Insurance Company covered from 2002 to 2005. The district court ruled that both insurers had a duty to defend and ordered them to equally share defense costs based on Ohio Casualty's 'equal shares' provision. Ohio Casualty challenged this decision, arguing for allocation based on 'time on the risk' as per Sharon Steel Corp. v. Aetna Casualty. The court decided to certify the issue to the Utah Supreme Court due to unresolved legal questions in Utah law concerning whether defense costs should be allocated under the 'equal shares' method or the 'time on risk' method. The appeal is stayed pending this certified question. The case highlights the complexities in interpreting insurance coverage clauses in successive policies and the allocation of defense costs.

Legal Issues Addressed

Allocation of Defense Costs in Successive Insurance Policies

Application: The court considered whether defense costs should be allocated based on 'equal shares' or 'time on the risk,' seeking guidance from the Utah Supreme Court due to ambiguity in Utah law.

Reasoning: Due to the unresolved legal issues surrounding Utah law, the court seeks guidance from the Utah Supreme Court on whether the defense costs should be allocated under the 'equal shares' method or the 'time on risk' method.

Duty to Defend Under Insurance Policies

Application: The case examines whether Ohio Casualty and Unigard Insurance are obligated to defend the Cloud Nine defendants in a lawsuit based on allegations of patent infringement and other claims.

Reasoning: The district court ruled in favor of Unigard's partial summary judgment motion, determining that Ohio Casualty had a duty to defend the EdiZone case due to the allegations of an advertising injury and mandated that both insurers equally share defense costs.

Interpretation of Insurance Coverage Periods

Application: The dispute involves whether coverage applies to successive policies, with Ohio Casualty arguing that Unigard's coverage did not overlap during its policy period, invoking the 'time on the risk' allocation.

Reasoning: Ohio Casualty contends that the district court incorrectly applied the 'other insurance' provision, arguing it only applies if there is concurrent coverage for a loss.

Other Insurance Clause in Insurance Policies

Application: The district court applied the 'other insurance' provision to mandate equal sharing of defense costs, although Ohio Casualty argued it should only apply to concurrent policies.

Reasoning: The district court determined that both insurers had a duty to defend and ordered them to equally share the defense costs based on the 'equal shares' provision in Ohio Casualty’s policy.
