denial of indemnity coverage under a renter’s insurance policy. We review a district
court’s grant of summary judgment de novo. Whitman v. Mineta, 541 F.3d 929, 931
(9th Cir. 2008). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
Tomas’s claims arise from an arbitration award entered against her after the
buyers of her former home alleged damage caused by pet urine during her post-sale
occupancy. In her first Oregon state court action, Tomas sought a declaration that
Allstate had a duty to defend her in the arbitration. The state court granted summary
judgment for Allstate, holding that there was no duty to defend because no coverage
existed under the policy due to several exclusions, including those for contaminants,
property occupied by the insured, and contractual liability. Tomas then filed the
instant lawsuit in Oregan state court, raising claims for declaratory relief, breach of
contract, and negligence per se based on Allstate’s alleged duty to indemnify.
Following removal, the federal district court found that Tomas’s claims are barred
under the doctrine of issue preclusion and granted summary judgment to Allstate.
1. The district court correctly held that issue preclusion bars Tomas’s claims
for declaratory relief and breach of contract in her second lawsuit. Issue preclusion
“forecloses relitigation of factual or legal issues that have been actually and
necessarily decided in earlier litigation.” San Remo Hotel, L.P. v. S.F. City & Cnty.,
364 F.3d 1088, 1094 (9th Cir. 2004). A federal court sitting in diversity applies the
preclusion law of the state where it sits. Daewoo Elecs. Am. Inc. v. Opta Corp., 875
2
F.3d 1241, 1244 (9th Cir. 2017). Under Oregon law, issue preclusion applies when
an issue of ultimate fact or law was actually litigated and essential to a final
judgment, among other requirements not disputed here. See Nelson v. Emerald
People’s Util. Dist., 862 P.2d 1293, 1296–97 (Or. 1993).
In Tomas’s first lawsuit, the state court conclusively determined that Allstate
had no duty to defend Tomas because there was not a potentially covered
“occurrence” since the alleged property damage fell squarely within the policy’s
exclusions. That determination controls the question of indemnification in this
lawsuit because Tomas already had a full and fair opportunity to litigate the meaning
and application of the policy’s coverage and exclusions. As a result, her attempt to
relitigate the identical coverage question is precluded absent any new legal or factual
developments to justify a different result. See id. at 1297.
Although the duty to indemnify is distinct from the duty to defend under
Oregon law, see Ledford v. Gutoski, 877 P.2d 80, 82–85 (Or. 1994) (en banc), here
both duties are controlled by the same interpretation of the scope of coverage
provided by the policy. See Twigg v. Admiral Ins. Co., 525 P.3d 478, 485 (Or. Ct.
App. 2023), overruled on other grounds, 373 Or. 445 (2025). Because the state
court’s decision in the first case regarding the duty to defend was wholly premised
on an interpretation of (non)coverage under the policy, the district court properly
3
concluded that the coverage issue was already resolved in the first lawsuit, could not
be relitigated, and thus Allstate had no duty to indemnify Tomas.
2. The district court also correctly held that issue preclusion bars Tomas’s
negligence per se claim. That claim contends that Allstate failed to comply with the
provisions of an Oregon statute regarding unfair claim settlement practices. See Or.
Rev. Stat. § 746.230. The issue of whether Allstate was obligated to indemnify
Tomas for the arbitration award was conclusively resolved in the first lawsuit and
that issue is essential to this negligence per se claim. Tomas does not otherwise
identify a legally protected interest that was not resolved in the first lawsuit. Issue
preclusion therefore bars Tomas’s negligence per se claim.
AFFIRMED.
