State v. Trombley: Ability-to-Pay Harmonization Validates Mandatory DUI Minimum Fines (If Suspendable), and Probation Cannot Reinstate Suspended Monetary Sanctions

1. Introduction

In State v. Trombley, 2026 MT 77, the Montana Supreme Court reviewed a combined judgment from the Twentieth Judicial District Court (Lake County) that (i) revoked a prior suspended sentence and (ii) imposed sentences in three new felony cases. Michael Ross Trombley (Defendant/Appellant) challenged only two monetary/conditions components tied to his felony DUI—fourth or subsequent offense.

The appeal presented two core issues:

  1. Whether the District Court imposed an illegal sentence by assessing a mandatory minimum $5,000 fine under § 61-8-1008(1)(a)(i), MCA (2021), even though the court fully suspended that fine after considering Trombley’s finances.
  2. Whether the judgment unlawfully delegated to the probation office the authority to “reinstate” suspended fines and fees upon perceived noncompliance with probation.

The State conceded the delegation issue but defended the fine. The Supreme Court affirmed the fine’s imposition-and-suspension and remanded to strike the improper delegation condition.

2. Summary of the Opinion

The Court held:

  • The $5,000 mandatory minimum felony DUI fine under § 61-8-1008(1)(a)(i), MCA was not an illegal sentence where the sentencing court: (a) considered ability to pay under § 46-18-231(3), MCA, (b) imposed the statutory minimum fine, and (c) used its suspension authority under § 46-18-201(2), MCA to suspend the fine entirely based on inability to pay.
  • The District Court lacked authority to delegate to probation and parole the power to reinstate suspended monetary sanctions; only the court may modify/revoke conditions under § 46-18-203, MCA. The Court ordered Condition No. 14 stricken on remand.

A concurrence/dissent agreed on the unlawful delegation but rejected the majority’s approach to mandatory fines, arguing that suspending a fine does not cure the illegality of imposing a fine on someone unable to pay, emphasizing the statutory language of § 46-18-231(3), MCA and the constitutional concerns discussed in earlier cases.

3. Analysis

3.1. Precedents Cited

The decision is best understood as an application of the Court’s then-recent “harmonization” framework for mandatory minimum fines and ability-to-pay requirements.

State v. Daricek, 2018 MT 31

Cited for the standard of review: the legality of a sentence is reviewed de novo. This framing matters because Trombley’s challenges were treated as pure questions of law about statutory authority and constitutional/statutory limits on sentencing.

State v. Gibbons, 2024 MT 63, cert. denied, ___ U.S. ___, 145 S. Ct. 355 (2024)

Trombley’s primary attack relied on State v. Gibbons, which held that a mandatory fine scheme (there, under § 61-8-731(3), MCA (2019)) was facially unconstitutional because it removed sentencing discretion needed to evaluate proportionality factors, including the offender’s ability to pay.

In Trombley, however, Gibbons did not control because it had already been limited by State v. Cole (discussed next). The majority expressly relied on Cole and noted that Cole overruled Gibbons in relevant part.

State v. Cole, 2026 MT 52

State v. Cole is the operative precedent. The Court in Cole held that § 46-18-231(3), MCA (ability-to-pay limitation on sentencing a fine) can be harmonized with statutes imposing “mandatory minimum” fines by requiring two steps:

  1. Determine the defendant’s ability to pay (as § 46-18-231(3), MCA requires).
  2. Impose the mandatory minimum fine, but then use § 46-18-201(2), MCA to suspend the fine to the extent the defendant cannot pay.

Trombley is a straightforward extension of Cole to the 2021 felony DUI penalty provision, § 61-8-1008(1)(a)(i), MCA, with the Court emphasizing that the relevant language of §§ 46-18-201(2)(a) and 46-18-231(3) remained identical in the 2021 MCA.

City of Whitefish v. Curran, 2023 MT 118

Cited for the principle that penalties are applied based on the statute in effect at the time of the offense. It anchors the Court’s use of the 2021 MCA for Trombley’s felony DUI.

City of Whitefish v. Curran, 2026 MT 65

Cited as further support consistent with Cole, signaling that the Court is building a coherent post-Cole line of cases on mandatory fines and suspension authority.

State v. Arellano, 2024 MT 108

Used to reject the State’s waiver argument. Arellano reiterates that a defendant cannot “agree” to an illegal sentence via plea agreement. Thus, even though Trombley’s plea agreement contemplated the fine, he could still challenge its legality.

State v. Mingus, 2004 MT 24, overruled in part by Gibbons, ¶ 64

The Court noted that, at the time of Trombley’s plea, prior “controlling authority” (including State v. Mingus) had treated § 46-18-231(3), MCA as inapplicable to mandatory fines. This historical point explains why the legal landscape shifted: Gibbons disrupted Mingus, and Cole then reframed the analysis through harmonization rather than facial invalidation.

Section 46-18-203, MCA (and the Court’s non-delegation point)

Although not a “precedent case,” the Court’s second holding rests on a core sentencing principle: only the district court may revoke, continue, or modify conditions of a suspended sentence. The Court relied on § 46-18-203(7)(a), MCA to conclude the probation office cannot be granted reinstatement power over suspended monetary sanctions.

Dissent’s additional authorities: State v. Yang, 2019 MT 266; State v. Vaska, 2025 MT 168; State v. Lenihan, 184 Mont. 338 (1979); and several out-of-state/federal cases

The concurrence/dissent invoked State v. Yang and Gibbons for the constitutional proposition that ability-to-pay is integral to proportionality in monetary sanctions, and cited State v. Vaska to criticize the Court’s shift toward overruling Gibbons. It further relied on State v. Lenihan to stress that sentencing authority is strictly statutory. The dissent also canvassed decisions such as City of Seattle v. Long, People v. Cowan (citing United States v. Bajakajian), Oregon v. Goodenow, Stuart v. State Dep't of Safety, Colo. Dep't of Lab. & Emp. v. Dami Hosp., LLC, United States v. Levesque, arguing that modern excessive-fines doctrine commonly requires meaningful consideration of ability to pay.

3.2. Legal Reasoning

(A) The mandatory minimum fine is lawful when paired with ability-to-pay findings and suspension authority

The Court’s core reasoning is statutory harmonization:

  • § 61-8-1008(1)(a)(i), MCA requires a minimum fine for felony DUI (fourth/subsequent).
  • § 46-18-231(3), MCA provides that a judge “may not sentence an offender to pay a fine unless the offender is or will be able to pay the fine.”
  • § 46-18-201(2), MCA authorizes a sentencing judge to “suspend execution of [a] sentence, unless specifically provided by statute.”

Applying State v. Cole, the Court treated the “mandatory fine” requirement as compatible with ability-to-pay limits because the court can impose the minimum fine to satisfy the penalty statute, while immediately suspending it (in whole or part) to avoid requiring payment the defendant cannot make.

On the facts, the Court emphasized the record showed the District Court: (1) considered Trombley’s financial circumstances; (2) imposed the $5,000 minimum; and (3) suspended it entirely—thereby rendering the sentence “not illegal.”

(B) Delegation to probation and parole to “reinstate” suspended monetary sanctions is unauthorized

Condition No. 14 attempted to empower the probation office to “reinstate” suspended fines/fees if it found probation noncompliance. The Court treated this as a core judicial function reserved by statute to the district court under § 46-18-203, MCA. Because the Legislature assigned revocation/modification authority to the court, the district court could not reassign it to the executive branch (probation and parole).

The remedy was narrow and surgical: affirm the rest of the judgment but remand for an amended judgment striking Condition No. 14.

(C) The concurrence/dissent’s critique: “imposition” versus “payment obligation”

The concurrence/dissent argued the majority’s approach collapses a critical distinction: even if collection is suspended, the court still “sentences an offender to pay a fine” when it imposes it—an action the dissent reads as prohibited by § 46-18-231(3), MCA where inability to pay exists. On that view, suspension does not cure illegality; rather, inability to pay prevents imposition in the first place.

3.3. Impact

  • Stabilization of mandatory-minimum fine sentencing post-Cole: Trombley reinforces that Montana courts may continue to impose statutory minimum fines for felony DUI, so long as they (a) assess ability to pay and (b) suspend all or part of the fine consistent with that assessment. This reduces the likelihood of successful facial constitutional attacks on mandatory-fine provisions—at least under the majority’s current interpretive framework.
  • Practical sentencing template: Trial courts now have a clear compliance roadmap: make an ability-to-pay record, impose the statutory amount, then suspend to the extent necessary. Defense counsel will likely focus on building a detailed financial record and ensuring the written judgment accurately reflects suspension decisions.
  • Limits on probation-office power: The remand to strike Condition No. 14 underscores a bright-line rule: probation may supervise and report, but it may not be given unilateral authority to reactivate suspended financial penalties. Future judgments will likely avoid similar delegation language, or defendants will have strong grounds to challenge it.
  • Continuing doctrinal tension: The concurrence/dissent signals ongoing instability: a change in Court composition or future litigation could revisit whether suspension truly satisfies statutory text and excessive-fines principles. Until then, Cole (as applied by Trombley) governs.

4. Complex Concepts Simplified

Mandatory minimum fine
A statute-set minimum dollar amount the court must include as part of the sentence for a particular offense. Under the majority’s approach, the court must impose that amount but may suspend it based on inability to pay.
Suspended fine
A fine that is imposed in the judgment but not immediately collectible (and may never become payable if conditions are satisfied). In Montana, suspension authority generally arises under § 46-18-201(2), MCA, unless a statute forbids suspension.
Ability-to-pay requirement (Montana)
§ 46-18-231(3), MCA restricts sentencing courts from ordering a defendant to pay a fine unless the defendant is or will be able to pay. The majority reads this as compatible with mandatory fines through suspension; the dissent reads it as a bar to imposing the fine at all if inability exists.
Delegation / non-delegation in sentencing conditions
Certain sentencing decisions—revoking, modifying, or continuing conditions—are assigned by statute to the court. A sentencing court cannot transfer that power to probation and parole; probation may monitor and recommend, but the court must decide.
Facial unconstitutionality
A claim that a statute is unconstitutional in all or most applications, not merely unconstitutional as applied to one defendant. Gibbons had adopted a facial approach to a mandatory DUI fine; Cole (and thus Trombley) moved away from that.

5. Conclusion

State v. Trombley solidifies two operational rules in Montana sentencing law:

  1. Following State v. Cole, a sentencing court may satisfy a felony DUI mandatory-minimum fine statute by imposing the minimum amount while honoring § 46-18-231(3), MCA through an ability-to-pay determination and suspending the fine under § 46-18-201(2), MCA to the extent the defendant cannot pay.
  2. A district court may not delegate to probation and parole the authority to reactivate suspended fines and fees; modification/revocation authority remains with the court under § 46-18-203, MCA.

The concurrence/dissent highlights enduring controversy: whether “impose then suspend” faithfully complies with the statutory text and excessive-fines principles. For now, Trombley confirms that, in Montana, the legality of mandatory fines hinges less on the fine’s nominal presence in the judgment and more on the court’s ability-to-pay inquiry and its use of suspension to prevent unpayable obligations—while keeping sentencing-modification power squarely in judicial hands.
