Utility-Owned Streetlight Evidence Is Admissible in Municipal Premises-Liability Claims; Public Duty Doctrine Does Not Categorically Bar Lighting-Based Unsafe-Intersection Theories

I. Introduction

In Sara Da' v. City of Bozeman (2026 MT 164), Jubilee Nesta Sara Da' (Plaintiff/Appellant) sought damages after being struck by a vehicle driven by Tasha Nelson while crossing a City-owned intersection and crosswalk in Bozeman. Sara Da' alleged the intersection was hazardous due to a combination of conditions: inadequate crosswalk markings, inadequate signage, and inadequate illumination because a streetlight positioned over the intersection was inoperative.

The City of Bozeman (Defendant/Appellee) did not own the streetlight; it was owned by NorthWestern Energy, which obtained summary judgment before trial. Relying on that summary-judgment ruling, the District Court excluded expert testimony and argument that the inoperative streetlight contributed causally to the collision—reasoning that streetlight-related negligence was not actionable against the City under premises liability and that the public duty doctrine (PDD) therefore shielded the City.

The Supreme Court of Montana reversed and ordered a new trial, holding that the PDD did not justify removing streetlight-related evidence from the jury simply because the light was utility-owned when the plaintiff’s claim is, in substance, a premises-liability challenge to the safety of a City-owned intersection as a whole.

II. Summary of the Opinion

  • Dispositive holding: The District Court erred as a matter of law by ruling that the PDD barred Sara Da' from introducing expert testimony and other evidence that an inoperative, utility-owned streetlight contributed to an unsafe condition at the City’s intersection and to Nelson’s collision with Sara Da'.
  • Scope of the Court’s ruling: The Court did not decide breach, notice, causation, or comparative fault; it held only that the streetlight’s inoperative condition could not be categorically removed from the jury’s consideration on PDD grounds.
  • Remedy: Reversal and remand for a new trial so Sara Da' may present liability evidence regarding the inoperative streetlight.

III. Analysis

A. Precedents Cited and Their Influence

1. The PDD framework and its limits: Gatlin-Johnson ex rel. Gatlin v. City of Miles City and Kent v. City of Columbia Falls

The majority grounded its analysis in two controlling Montana decisions that restrict overuse of the PDD where generally applicable tort duties supply the duty element:

  • Gatlin-Johnson ex rel. Gatlin v. City of Miles City, 2012 MT 302: The Court reiterated that a facility being open to the public does not mean “the public duty doctrine applies to any negligence claim” arising from its use. The majority in Sara Da' treated Gatlin-Johnson as confirming that ordinary premises-liability duties can apply to governmental entities without requiring a “special duty” showing.
  • Kent v. City of Columbia Falls, 2015 MT 139: The Court emphasized that the PDD “should not be applied by default” and does not eliminate a duty arising under “generally applicable principles of law,” including premises liability. In Sara Da', Kent supported the majority’s core move: reframing the dispute from a “streetlight duty” case into a “condition of City property” case in which lighting is one component of overall safety.

Together, these cases supplied the doctrinal anchor for the majority’s rule: if the plaintiff alleges an unsafe condition of City premises under ordinary negligence/premises principles, the PDD is not a categorical bar—nor a basis to strip a component condition (lighting) from the jury.

2. Third-party undertaking doctrine kept in its lane: Maryland Casualty Company v. Asbestos Claims Court and Restatement (Second) of Torts, § 324A

The District Court’s streetlight ruling leaned heavily on its earlier summary judgment for NorthWestern Energy, which was decided under Restatement (Second) of Torts, § 324A, as applied in Maryland Casualty Company v. Asbestos Claims Court, 2020 MT 70.

The majority accepted that § 324A and Maryland Casualty Company provided the right test for NorthWestern Energy’s potential duty as a third-party service provider—particularly reliance concepts under § 324A(c). But the Court held that this analysis did not resolve the City’s separate duties as the owner/maintainer of the intersection. Put differently, the absence of § 324A(c) reliance evidence might defeat a claim against the utility, but it does not dissolve the City’s premises-liability duty concerning the safety of its intersection.

3. Ownership is not always dispositive where the hazard affects safe use of the premises: Piedalue v. Clinton Elementary Sch. Dist. No. 32 and Dobrocke v. City of Columbia Falls

To rebut the City’s premise that “no ownership/control of the streetlight” ends the inquiry, the Court invoked Montana cases recognizing premises-liability exposure even when the immediate instrumentality is not owned by the defendant, so long as the hazard is sufficiently connected to the safe use of the defendant’s property:

  • Piedalue v. Clinton Elementary Sch. Dist. No. 32, 214 Mont. 99 (1984): Lack of title to the irrigation ditch did not defeat a premises claim where the hazard affected safe use of the defendant’s roadway.
  • Dobrocke v. City of Columbia Falls, 2000 MT 179 (overruled on other grounds by Roberts v. Nickey, 2002 MT 37): The City could owe premises duties for hazards affecting safe use of City property even if the hazard did not originate from the municipality; categorical ownership-based defenses were rejected.

These authorities supplied the connective principle the Court used here: utility ownership of a streetlight does not automatically sever lighting conditions from a municipality’s premises-liability case when the alleged danger is the condition of the municipal intersection as experienced by users.

4. Supporting negligence framework and standards of review

  • Bueling v. Swift, 1998 MT 112 and Lorang v. Fortis Ins. Co., 2008 MT 252: While evidentiary rulings are generally discretionary, legal determinations underlying evidentiary exclusions are reviewed de novo.
  • Seltzer v. Morton, 2007 MT 62: The Court must consider whether an erroneous exclusion affected substantive rights.
  • Peterson v. Eichhorn, 2008 MT 250: Summary-judgment review principles, including viewing evidence in favor of the nonmovant, informed the Court’s assessment of the District Court’s reliance on the NorthWestern summary judgment ruling.
  • Babcock v. Casey's Mgmt., LLC, 2021 MT 215 and § 27-1-701, MCA: Premises liability is negligence; landowners owe reasonable care to maintain safe conditions and warn of lurking dangers.

B. Legal Reasoning

1. Constitutional and statutory baseline: governments are not categorically immune

The Court began from Montana’s explicit anti-immunity baseline: Mont. Const. art. II, § 18 and §§ 2-9-101, -102, MCA provide that governmental entities are liable “under circumstances where the governmental entity, if a private person, would be liable.” The PDD is thus framed as a limited doctrine preventing undue judicial interference with governmental processes—not a general immunity.

2. The central doctrinal move: characterizing the claim as premises liability about a City-owned intersection

The majority held the District Court erred by treating utility ownership of the light as categorically removing lighting conditions from “the premises” and thereby triggering the PDD. The “relevant premises” were the City’s intersection and crosswalk in a high mixed-traffic area; the plaintiff’s theory was that the intersection was unsafe due to combined conditions (markings, signage, and illumination). Under Gatlin-Johnson and Kent, that framing keeps the case within ordinary premises-liability principles, where the PDD does not operate to negate duty by default.

3. A narrow holding: admissibility and jury consideration, not automatic municipal liability

The Court emphasized limits:

  • No holding that the City had a “general duty to patrol every streetlight.”
  • No holding that the City owed a “special duty” because the intersection was studied in safety planning.
  • No holding that the City breached a duty or had notice the light was out.

Instead, the holding is evidentiary-substantive: when unsafe premises is alleged, evidence of an inoperative streetlight positioned to illuminate the crossing cannot be categorically excluded solely due to utility ownership; ownership and maintenance responsibilities are for the jury’s evaluation of breach, notice, causation, and comparative fault.

4. “Leasing out” safety functions cannot become a duty-avoidance device

The Court expressed a policy concern: if a municipality could avoid premises liability whenever a safety-related component is owned/maintained by a third party, and the third party avoids liability due to lack of premises ownership or § 324A constraints, plaintiffs could be left without a responsible tortfeasor even when dangerous conditions exist in the functional environment of municipal property. The Court thus refused a rule that would allow municipalities to “lease out” integral safety functions and thereby categorically evade jury consideration of those conditions.

C. Impact

1. Litigation and trial practice in Montana

  • Expanded admissibility pathway: Plaintiffs can present lighting-condition evidence as part of an unsafe-condition theory against a municipality even when the light is utility-owned—so long as the theory is grounded in the condition and safe use of municipal premises.
  • Reduced force of PDD at the evidentiary gatekeeping stage: The PDD cannot be used categorically to exclude a subset of condition evidence where generally applicable premises duties are asserted.
  • Sharper separation of doctrines: Maryland Casualty Company v. Asbestos Claims Court and Restatement (Second) of Torts, § 324A are confirmed as tools for utility/third-party duty, not as a backdoor mechanism to shrink municipal premises duties.

2. Municipal risk management and inter-entity coordination

  • Cities may face stronger incentives to formalize notice/reporting protocols with utilities, document response pathways for outage reports near high-risk crossings, and incorporate illumination failures into intersection safety assessments.
  • The decision may increase the practical importance of indemnity/contractual allocation discussions between municipalities and utilities, even though the Court did not require any specific contractual arrangement.

3. The dissents’ fault lines and future doctrinal pressure points

Justice Rice’s Dissent framed the claim as a challenge to discretionary allocation of city-wide traffic-control resources—more akin to Prosser v. Kennedy Enters. Inc. and the PDD’s core purpose (also citing Nelson v. Driscoll and out-of-state authority such as King v. Town of Selmer). Justice Baker’s Dissent emphasized common-law “no duty to light” principles and argued the jury’s rejection of non-lighting theories left “lighting alone,” which should not create liability absent a “peculiar condition” requiring illumination (relying heavily on Mixon v. Pac. Gas & Elec. Co., Plattner v. City of Riverside, Glover v. Georgia Power Co., and other authorities).

The majority’s remand leaves open future disputes over how Montana courts distinguish (a) premises-condition negligence from (b) discretionary design/resource-allocation challenges—especially where plaintiffs plead both.

IV. Complex Concepts Simplified

  • Public Duty Doctrine (PDD): A rule limiting government liability when the government’s duty is owed to the public at large (e.g., general policing/regulatory functions). If the PDD applies, a plaintiff typically must show a “special duty” under recognized exceptions (as summarized in Kent v. City of Columbia Falls).
  • Premises liability: Ordinary negligence applied to property conditions; landowners must use reasonable care to keep premises reasonably safe and warn of hidden dangers (see Babcock v. Casey's Mgmt., LLC; § 27-1-701, MCA). Under Gatlin-Johnson ex rel. Gatlin v. City of Miles City, these generally applicable duties can apply to governmental entities.
  • Third-party undertaking (Restatement (Second) of Torts, § 324A): A doctrine imposing duty on a party who undertakes to render services for another and thereby harms a third person; reliance under § 324A(c) is often pivotal (as discussed in Maryland Casualty Company v. Asbestos Claims Court).
  • “Law of the case” (as used by the trial court): A principle that prior rulings in the same case may govern later phases. The Supreme Court effectively held the NorthWestern summary judgment ruling could not be treated as conclusively determining the City’s premises-liability evidentiary scope.
  • Comparative fault: A system where responsibility can be allocated among parties (and sometimes the plaintiff) based on their respective contributions to harm. The Court emphasized that utility ownership is relevant to comparative fault even if it is not a categorical duty bar.

V. Conclusion

Sara Da' v. City of Bozeman establishes an important evidentiary-and-duty clarification in Montana tort law: when a plaintiff alleges a City-owned intersection is unsafe under premises-liability principles, the public duty doctrine does not permit a categorical exclusion of evidence about an inoperative streetlight positioned to illuminate the crossing merely because the streetlight is owned by a utility company. Ownership and maintenance responsibility remain highly relevant—particularly to notice, breach, causation, and comparative fault—but they are not a per se gatekeeping rule that removes lighting from the jury’s consideration. The decision reinforces Montana’s constitutional and statutory commitment to governmental tort accountability while preserving factual questions for the finder of fact.
