Northwestern Mutual Life Insurance v. Weiher, 809 F.3d 394

Background

Douglas Weiher, a Minnesota resident and Wisconsin dentist, applied in 2010 for a Northwestern Mutual disability policy and agreed in writing to terminate an existing Great-West policy as a condition of issuance; Northwestern warned failure to cancel could lead to rescission.
Weiher signed an Amendment to Application promising to terminate the Great-West policy by its next premium due date but did not cancel that policy.
Weiher became disabled in 2012, filed claims; Great-West and Unum paid his claims; Northwestern discovered the Great-West policy remained in force and rescinded Weiher’s Northwestern policy.
Northwestern sued for rescission in federal district court in Minnesota; Weiher counterclaimed for breach of contract; both parties moved for summary judgment.
The district court treated Weiher’s promise as a promissory warranty and, applying Wisconsin law (Wis. Stat. § 631.11(3)), granted summary judgment for Northwestern, finding the un-cancelled policy increased Northwestern’s risk.
The Eighth Circuit majority reversed and remanded, holding Northwestern failed to show as a matter of law that Weiher’s failure to cancel increased the insurer’s risk at the time of loss; it left an alternative § 631.11(1)(b) misrepresentation theory for the district court to consider on remand. Judge Loken dissented, arguing Fox v. Catholic Knights controls and § 631.11(3) does not apply to this condition precedent.

Issues

Issue	Weiher's Argument	Northwestern's Argument	Held
Whether Northwestern could rescind under Wis. Stat. § 631.11(3) for breach of a promissory warranty	The statute requires the insurer to prove the breach existed at time of loss and increased the risk at that time; Northwestern did not meet that burden	The promise was a promissory warranty and its breach increased risk (over-insurance/moral hazard), so rescission is allowed	Reversed district court: Northwestern did not prove as a matter of law that breach increased risk at time of loss; summary judgment improper
What “risk” means under § 631.11(3) and whether over‑insurance qualifies	“Risk” should be read narrowly: risk of the insured becoming disabled; Northwestern didn’t show additional coverage increased that risk	“Risk” includes moral hazard/financial risk that over-insurance increases likelihood or severity of claim	Majority: unnecessary to resolve broadly; even assuming over‑insurance counts, Northwestern failed to show Weiher was over‑insured at time of loss
Whether evidence of Northwestern’s underwriting standards and affidavits establishes increased risk as a matter of law	Those materials don’t address whether risk increased at time of loss for this specific policy and claimant	Underwriting standards and declarant testimony show Northwestern would not have issued the policy and that over‑insurance raises risk	Majority: underwriting policies and general testimony insufficient to satisfy the clear-and-convincing standard for § 631.11(3) at summary judgment
Whether rescission might be available under § 631.11(1)(b) (misrepresentation/affirmative warranty)	Weiher says he accidentally failed to cancel (no intent to deceive); materiality/knowledge disputed	Northwestern argues the false promise was material and relied upon, supporting rescission under (1)(b)	Majority: factual disputes on knowledge/intent exist; district court did not decide this ground and should consider it on remand
