Section 10-3-1118 Limited to General Cooperation-Clause Defenses; Excess UIM Exhaustion Satisfied by Undisputed Damages Beyond Underlying Limits

I. Introduction

United Services Automobile v. Wenzell, Anthony (2026 CO 25) presented the Colorado Supreme Court with two recurring first-party insurance disputes arising from a rear-end collision and a complicated medical history: (1) the scope of Colorado’s “failure-to-cooperate” statute, section 10-3-1118, C.R.S. (2025), and whether its notice-and-cure procedures apply only to defenses based on a policy’s general cooperation clause or instead to any defense premised on the insured’s noncompliance with policy duties (including specific, enumerated duties such as signing medical-record authorizations); and (2) the meaning of “exhaustion” in an excess underinsured-motorist (UIM) setting where the excess policy contains an “other insurance” clause making it excess over “collectible” underlying insurance.

Parties. The petitioners were United Services Automobile Association (USAA) and State Farm Mutual Automobile Insurance Company. The respondent was Anthony Wenzell, an insured asserting breach of contract and bad-faith delay/denial after insurers sought broad medical releases to evaluate causation and apportionment between injuries from a prior accident and the accident at issue.

Procedural posture. The trial court granted summary judgment to the insurers, treating the medical-release requirement as a condition precedent and also ruling (as relevant here) that USAA had no bad-faith exposure until underlying coverage was “exhausted.” The court of appeals reversed in a published decision, Wenzell v. United Servs. Auto. Ass'n, 2024 COA 40, reading section 10-3-1118 broadly and concluding that “exhaustion” could not be tied to an underlying carrier’s policy-limits payment. The Supreme Court granted certiorari and affirmed in part and reversed in part.

II. Summary of the Opinion

Section 10-3-1118 (failure-to-cooperate procedures) is narrow. The Court held that section 10-3-1118’s procedural prerequisites apply only when the insurer asserts a defense arising from the policy’s general cooperation clause. The statute does not proceduralize defenses based on failure to satisfy specific, enumerated conditions precedent in the contract (such as a medical-authorization provision).
Excess UIM exhaustion is satisfied by “undisputed damages,” not by actual payment. The Court agreed with the court of appeals that an excess UIM carrier cannot condition its obligation to investigate/adjust on the primary UIM carrier’s tender of policy limits. It clarified that exhaustion clauses are enforceable only if “exhaustion” means the insured has shown undisputed damages exceeding the maximum limits of all underlying policies.
Disposition and remand. The Court directed that summary judgment be entered for the insurers on the condition-precedent issue, and it indicated that bad-faith claims fall with coverage where a condition precedent bars recovery (citing Jensen v. Am. Fam. Mut. Ins. Co.). It also rejected the court of appeals’ conclusion that exhaustion clauses inherently violate section 10-4-609(1)(c), allowing them in the excess UIM context so long as they track the “undisputed damages” concept.

III. Analysis

A. Precedents Cited

1. Statutory interpretation framework and common-law carryover

Apodaca v. Allstate Ins. Co.: supplied de novo review principles for interpreting the insurance code and reinforced that statutory meaning is a legal question for the Court.
Skillett v. Allstate Fire & Cas. Ins. Co.: anchored the “plain language first” approach and the directive to give effect to legislative intent.
Vigil v. Franklin and United States v. Hansen: supported the inference that when the legislature employs a common-law term, the existing common-law backdrop (“old soil”) accompanies it unless clearly displaced.
Beach v. Beach: provided the canon against implied abrogation of the common law—central to the Court’s choice to preserve the common-law separation between cooperation-clause defenses and condition-precedent defenses.
Cowen v. People: justified the Court’s use of ordinary dictionaries to identify potential meanings of “cooperate,” which in turn supported its finding of ambiguity in section 10-3-1118’s undefined terminology.

2. Cooperation clauses vs. conditions precedent (and prejudice)

State Farm Mut. Auto. Ins. Co. v. Brekke: the Court relied on Brekke to describe how policies often define cooperation and—critically—to distinguish “duties of cooperation” from “an additional list of duties” (conditions or other enumerated obligations) tied to claim evaluation. Brekke’s conceptual separation set up the holding that section 10-3-1118 targets the former, not the latter.
Soicher v. State Farm Mut. Auto. Ins. Co.: used to articulate that a classic failure-to-cooperate defense requires a showing that the insured’s noncooperation “materially and substantially disadvantaged the insurer,” i.e., actual prejudice. This prejudice requirement reinforced the Court’s view that “failure to cooperate” is a distinct doctrine, not a synonym for any contractual noncompliance.
State Farm Mut. Auto. Ins. Co. v. Goddard: cited as an example of appellate treatment distinguishing a policy’s cooperation clause from other enumerated duties, supporting the Court’s view that Colorado law recognizes multiple, separable contractual obligations.
Ahmadi v. Allstate Ins. Co.: referenced for the proposition that failure to cooperate and failure to satisfy conditions precedent are distinct concepts.
Jensen v. Am. Fam. Mut. Ins. Co.: supplied the rule applied on remand—failure to comply with a condition precedent bars recovery under the policy, which in turn collapses associated bad-faith theories premised on a duty to pay under the contract.

3. Excess UIM exhaustion, freedom of contract, and statutorily mandated coverage

Bailey v. Lincoln Gen. Ins. Co.: recognized freedom to contract in insurance, but also the Court’s authority to invalidate provisions contrary to public policy—used as a lens for evaluating exhaustion clauses.
Meyer v. State Farm Mut. Auto. Ins. Co. (and its treatment in Schlessinger v. Schlessinger ex rel. Schlessinger): the Court invoked Meyer’s principle that insurers may not “dilute, condition, or limit statutorily mandated coverage.” This was pivotal in rejecting a payment-limits exhaustion rule that would allow an excess carrier to postpone duties based on another insurer’s payment behavior.
Shelter Mut. Ins. Co. v. Mid-Century Ins. Co.: supported the legality of “other insurance” ordering provisions generally, situating USAA’s excess position within permissible UIM coordination.
Pub. Serv. Co. of Colo. v. Wallis & Cos.: acknowledged as an earlier use of “must first be exhausted” language, but the Court explained it had not previously defined “exhaustion” for UIM, leaving room for the present clarification.
Ligotti v. Allstate Fire & Casualty Insurance Co.: although not binding, it was adopted as consistent with Colorado’s UIM scheme; it supplied the core rationale that excess UIM liability turns on damages exceeding underlying limits, not on the amount the underlying insurer actually pays.
Waste Mgmt. of Minn., Inc. v. Transcon. Ins. Co. and Citigroup Inc. v. Fed. Ins. Co.: used as contrasting out-of-jurisdiction exemplars of (respectively) the “undisputed-damages” approach and the “payment-limit” approach to exhaustion.
Jordan v. Safeco Ins. Co. of Am., Inc.: cited alongside Meyer to reinforce that conditioning UIM coverage on a particular sequence or payment can conflict with Colorado’s statutory design.
State Farm Mut. Auto. Ins. Co. v. Fisher: used to cabin concerns about inflated claims by tying statutory bad-faith exposure to the insurer’s treatment of undisputed covered benefits.
Westin Operator, LLC v. Groh: supplied the summary-judgment standard—no genuine dispute as to any material fact.

4. The dissent’s competing authorities (illustrating the contested meaning of “failure-to-cooperate”)

Justice Berkenkotter’s dissent cited a line of cases and interpretive principles to argue that section 10-3-1118 is plain, broad, and aimed at preventing insurers from weaponizing noncooperation claims (especially around medical authorizations). The dissent invoked: Farmers Auto. Inter-Insurance Exch. v. Konugres (historical recognition of cooperation duties), State Farm Mut. Auto. Ins. Co. v. Secrist, Cribari v. Allstate Fire & Cas. Ins. Co., and Polland v. State Farm Mut. Auto. Ins. Co. to show variability in “noncooperation” characterizations; and interpretive rules from Turbyne v. People and People v. Guenther (do not add words), plus an absurdity-avoidance principle drawn from Archuleta v. Roane.

B. Legal Reasoning

1. Section 10-3-1118: procedural gatekeeping limited to the general cooperation clause

The Court framed the threshold question as whether the statutory “failure-to-cooperate defense” merges (or was meant to merge) the broader universe of defenses based on breach of any policy duty, including enumerated claim-handling duties characterized as conditions precedent. It answered no.

The reasoning ran in three steps:

Common-law taxonomy matters. Drawing on State Farm Mut. Auto. Ins. Co. v. Brekke and Soicher v. State Farm Mut. Auto. Ins. Co., the Court treated (a) failure-to-cooperate under a general cooperation clause and (b) breach of specific, enumerated conditions precedent as distinct defenses with different elements—most notably, prejudice is essential to the former but not necessarily to the latter.
Ambiguity does not equal abrogation. Because section 10-3-1118 uses “cooperate” without definition, the Court found the term susceptible to a colloquial meaning (any compliance) or a technical/common-law meaning (cooperation clause doctrine). The Court then applied Beach v. Beach to require a clear statement before concluding the legislature displaced the common law’s distinctions.
Legislative history was not “clear” enough to broaden the statute beyond the common-law category. The Court acknowledged committee statements that could be read broadly, but it concluded the record did not clearly evidence an intent to collapse all policy duties into the statutory “failure-to-cooperate” label. Therefore, section 10-3-1118 governs only defenses arising from the general cooperation clause.

Applying that construction, the insurers’ defense—failure to provide adequate medical releases required by specific policy language—was treated as a condition-precedent issue, not a statutory failure-to-cooperate defense. Section 10-3-1118’s notice-and-cure procedures therefore did not apply.

Notably, the Court added a cautionary note: its holding should not be read as permission for insurers to draft “novel or unduly onerous” conditions precedent to evade the statute, and it left open potential statutory bad-faith exposure for bad-faith use of conditions precedent.

2. Excess UIM exhaustion: enforceable, but only via “undisputed damages” exceeding underlying limits

On exhaustion, the Court harmonized three commitments: (i) honoring contractual ordering of coverage (excess vs. primary), (ii) preventing policy terms from conditioning or limiting statutorily mandated UIM coverage, and (iii) aligning bad-faith duties with the “undisputed benefits” concept.

The Court surveyed two exhaustion models used elsewhere—Waste Mgmt. of Minn., Inc. v. Transcon. Ins. Co. (damages-based) versus Citigroup Inc. v. Fed. Ins. Co. (payment-based)—and adopted the damages-based model for Colorado’s UIM context. It did so largely because:

Conditioning excess UIM duties on the primary carrier’s policy-limits payment would “condition” coverage in tension with Meyer v. State Farm Mut. Auto. Ins. Co. and related UIM policy cases (including Jordan v. Safeco Ins. Co. of Am., Inc.).
Colorado’s UIM statute prohibits reducing UIM coverage by setoffs tied to “other uninsured or underinsured motor vehicle insurance,” and the Court read that policy as inconsistent with an exhaustion definition that turns on underlying payment amounts rather than the insured’s loss.
Concerns about inflated claims are mitigated by State Farm Mut. Auto. Ins. Co. v. Fisher, because bad-faith liability turns on delay/denial of undisputed covered benefits, not on disputes about valuation or causation.

The Court therefore recognized an enforceable role for exhaustion clauses in excess UIM policies, but only if exhaustion is satisfied when the insured demonstrates undisputed damages that exceed the maximum limits of all underlying policies—rather than when the insured actually collects those limits.

C. Impact

1. Impact on section 10-3-1118 litigation

Narrowed reach of notice-and-cure. Insurers may avoid section 10-3-1118’s procedures when they plead noncompliance as breach of a specific, enumerated policy requirement (a condition precedent), rather than as breach of the general cooperation clause.
Higher stakes for “conditions precedent” drafting and enforcement. The Court’s caveat signals future scrutiny: policy terms labeled “conditions precedent” may invite litigation over whether they are “unduly onerous” or used in bad faith.
Practical pleading consequences. The decision incentivizes careful characterization of defenses and may shift more disputes into contract-interpretation fights over whether a given policy term is truly a condition precedent versus part of cooperation.

2. Impact on excess UIM claim handling

Excess carriers cannot wait on primary carriers’ tenders. Where undisputed damages exceed underlying limits, excess carriers must begin investigating/adjusting and pay undisputed amounts above those limits.
But “undisputed” is the trigger. The Court’s formulation gives excess carriers a defensible basis to defer paying (and potentially to defeat bad-faith claims) where causation, apportionment, or valuation prevents the insured from showing “undisputed” damages above underlying limits.
Coordination without forfeiture. The rule preserves lawful excess ordering (per Shelter Mut. Ins. Co. v. Mid-Century Ins. Co.) while preventing exhaustion clauses from operating as de facto barriers to UIM benefits.

IV. Complex Concepts Simplified

Failure-to-cooperate defense: A common-law defense tied to the policy’s general cooperation clause—e.g., the insured refuses to assist in investigation or litigation. Under Soicher v. State Farm Mut. Auto. Ins. Co., the insurer typically must show it was materially and substantially disadvantaged (prejudiced).
Condition precedent: A specific contractual requirement that must be satisfied before coverage is owed (here, providing a required authorization). Under Jensen v. Am. Fam. Mut. Ins. Co., failure to satisfy a condition precedent can bar recovery under the policy.
Section 10-3-1118’s notice-and-cure scheme: A statute that imposes procedural steps before an insurer may assert a failure-to-cooperate defense—timely written notice, a chance to cure, and a reasonableness limitation on the information requested. After this decision, those procedures apply only to defenses arising from the general cooperation clause.
Excess UIM and “exhaustion”: “Excess” UIM applies only after the insured’s damages exceed underlying coverage limits. After this decision, “exhaustion” may be enforced only as a damages-based concept: it is satisfied when the insured shows undisputed damages exceeding underlying limits—not when underlying carriers have actually paid policy limits.
Undisputed damages: Amounts that are not reasonably contested on coverage/causation/valuation; under State Farm Mut. Auto. Ins. Co. v. Fisher, statutory bad faith turns on delay/denial of such undisputed covered benefits.

V. Conclusion

United Services Automobile v. Wenzell, Anthony establishes two consequential rules in Colorado insurance law: (1) section 10-3-1118’s procedural protections attach only to defenses based on a policy’s general cooperation clause, not to defenses framed as breach of specific, enumerated conditions precedent; and (2) in excess UIM coverage, exhaustion clauses remain permissible but only when “exhaustion” is satisfied by the insured’s demonstration of undisputed damages exceeding underlying limits, not by the underlying carrier’s policy-limits payment.

The majority’s narrowing construction of section 10-3-1118 creates a sharper boundary between “cooperation” doctrine and contract conditions—while the dissent warns that the boundary invites circumvention and undermines the statute’s remedial purpose. On the UIM side, the Court’s “undisputed damages” trigger aims to preserve excess ordering without allowing payment-dependent exhaustion to erode the statutory promise of UIM protection.
