Colorado Reaffirms Strict Liability for Felony Hit-and-Run and Applies Harmless-Error Review to Habitual-Offender Jury Omissions

1. Introduction

Brown v. People addresses two consequential questions at the intersection of criminal liability and constitutional procedure: whether Colorado may punish felony leaving-the-scene offenses without proof of any culpable mental state, and whether a habitual-offender sentence must be overturned when a judge, rather than a jury, makes the necessary findings about prior criminal episodes.

The court preserved its existing strict-liability interpretation of Colorado’s leaving-the-scene statute. It also upheld the facial constitutionality of the former habitual-offender scheme while concluding that any error in denying Brown the required jury determination was harmless beyond a reasonable doubt. The decision therefore principally reaffirms and applies existing precedent rather than creating an entirely new framework.

Background and proceedings

In June 2017, Jason P. Brown drove his truck into an alley and over two people sleeping beneath a white blanket. One victim sustained serious injuries requiring emergency surgery; the other died that night. A witness told Brown that he had run over the victims. Brown denied doing so and drove away.

Police later located Brown at his home. Officers observed signs associated with alcohol consumption, although Brown said he had not consumed alcohol until arriving home. Those observations formed part of the factual background; the opinion’s holdings do not depend on a determination that he committed an intoxicated-driving offense.

The prosecution charged Brown with leaving the scene of an accident resulting in death, referred to as “LTS (death),” and leaving the scene of an accident resulting in serious bodily injury, referred to as “LTS (SBI).” It also added habitual-criminal counts under the statutory scheme then in force. Brown challenged that scheme and demanded a jury trial on the habitual-criminal allegations.

The jury instructions on the leaving-the-scene charges required proof of Brown’s direct involvement in the accident, the resulting death or serious bodily injury, and his failure to perform the statutory stopping and assistance duties. They required no proof that Brown acted intentionally, knowingly, recklessly, or negligently. The jury convicted him of both offenses. The judge then adjudicated him a habitual offender, and Brown received an aggregate sixty-year prison sentence.

The court of appeals affirmed in People v. Brown. It regarded the strict-liability issue as controlled by existing Colorado Supreme Court precedent and alternatively found any omission of a knowledge requirement harmless beyond a reasonable doubt. It also rejected Brown’s constitutional challenge to the habitual-offender statute. The supreme court granted review of both issues.

2. Summary of the Opinion

• No mental-state element for the leaving-the-scene offenses: People v. Manzo remains controlling. The prosecution need not prove a culpable mental state for LTS (death) or LTS (SBI).
• No displacement by federal precedent: The majority concluded that Rehaif v. United States did not overrule or undermine People v. Manzo sufficiently to justify abandoning it.
• Increased penalties did not change the statutory interpretation: The legislature raised the offenses’ felony classifications without adding a mental-state requirement.
• The former habitual-offender scheme was not facially unconstitutional: Under People v. Gregg, it could operate constitutionally by allowing a jury to determine whether qualifying convictions arose from separate and distinct criminal episodes.
• The jury omission did not require reversal: Any error in Brown’s judge-only habitual-offender adjudication was nonstructural and harmless beyond a reasonable doubt on the particular record.

Justice Samour agreed that Brown’s convictions and sentence should stand. He nevertheless rejected the majority’s strict-liability reasoning. In his view, the statute should require knowledge of involvement in an accident of the kind that triggers a duty to stop. He would have affirmed the challenged conviction because the evidence of Brown’s awareness made the instructional omission constitutionally harmless.

That distinction matters: the majority found no leaving-the-scene instructional error; Justice Samour found an error but no reversible prejudice.

3. Analysis: Standards of Review and Governing Precedents

Three preliminary precedents established the court’s review framework:

• Roberts v. People required de novo review of whether the jury instructions correctly stated the governing law. The supreme court therefore independently evaluated whether a mental-state element belonged in the instructions.
• Dean v. People supplied de novo review for both facial and as-applied constitutional challenges to statutes.
• Hagos v. People supplied the standard for preserved constitutional trial error: reversal is required unless the prosecution proves harmlessness beyond a reasonable doubt. A reasonable possibility that the error contributed to the result defeats harmlessness.

These standards separated two inquiries that might otherwise become blurred. First, the court had to decide what the law required. Only if a constitutional trial error existed did it need to determine whether that error justified reversal.

4. Strict Liability for Leaving the Scene

A. The controlling precedent: People v. Manzo

In People v. Manzo, 144 P.3d 551 (Colo. 2006), the court held that LTS (SBI) was a strict-liability offense. Although the statute did not expressly label the offense “strict liability,” the court interpreted its mandatory stopping obligations as requiring no culpable mental state and treated the offense as falling within the public-welfare category.

Brown challenged both the continuing validity and the applicability of that decision. He argued that later United States Supreme Court authority strengthened the presumption favoring mental-state requirements and that increased felony penalties made the earlier decision unsuitable for the present offenses.

The majority rejected both arguments. Its holding expressly covers LTS (death) and LTS (SBI), even though the first certiorari question referred specifically to the death-resulting offense. The court explained that Brown’s substantive arguments applied equally to both.

B. Stare decisis: stability as the starting point

Love v. Klosky supplied the majority’s test for departing from precedent. The court must be clearly convinced both that the earlier rule was originally erroneous or has become unsound because of changed conditions, and that abandoning it would produce more good than harm.

This framework placed the burden on Brown to establish a sufficient reason for changing settled law. The majority did not approach the statute as an entirely open interpretive question. It asked whether subsequent developments justified displacing an established construction and concluded that they did not.

C. Why Rehaif v. United States did not change the result

Rehaif v. United States, 588 U.S. 225 (2019), concerned federal firearm provisions containing an express “knowingly” requirement. The question was whether that requirement applied both to firearm possession and to the defendant’s prohibited status. The Supreme Court held that it did.

Brown relied on the decision’s broader discussion of the presumption of scienter, including its observation that courts typically decline to apply that presumption to regulatory or public-welfare provisions carrying only minor penalties. He argued that serious felony punishment could not comfortably coexist with complete strict liability.

The majority gave four reasons for rejecting that reading:

1. Different statutory questions: Rehaif v. United States addressed the reach of an expressly enacted mental state. Colorado’s statute contains no express mental state, making the issue whether one should be implied.
2. Dicta rather than a controlling rule: The majority characterized the federal decision’s broader observations about statutes without scienter requirements as unnecessary to the question actually decided.
3. A qualified formulation: The word “typically” signaled a general approach rather than an exceptionless prohibition.
4. Penalty severity was not dispositive: The majority read the federal decision as preserving a contextual inquiry, not establishing that a sufficiently severe penalty automatically invalidates strict liability.

The majority thus understood Rehaif v. United States as an application of longstanding interpretive principles, not a doctrinal change requiring the abandonment of People v. Manzo. Its conclusion is limited to the offenses and arguments before it; the opinion does not announce that every serious felony may constitutionally dispense with a mental-state requirement.

D. Statutory amendments and legislative acceptance

The legislature amended section 42-4-1601 four times after People v. Manzo. Most importantly, it elevated LTS (death) from a class 4 to a class 3 felony in 2008 and LTS (SBI) from a class 5 to a class 4 felony in 2012. It did not add a mental-state element.

The majority relied on two interpretive precedents:

• Griego v. People presumes that the General Assembly legislates with awareness of existing judicial decisions.
• People v. Swain treats amendment of a previously construed statute, without changing the construed language, as acceptance and ratification of that construction.

Applied together, those principles supported an inference that the legislature accepted the strict-liability interpretation while increasing punishment.

The legislative hearings supplied a related policy explanation. Lawmakers wanted to eliminate an incentive for intoxicated drivers to flee, sober up, and face a lower-level leaving-the-scene charge rather than a more serious intoxication-based vehicular offense. Aligning felony classifications reduced that disparity.

For the majority, the amendments therefore reinforced rather than weakened the existing interpretation. The court considered judicial insertion of “knowingly” inconsistent with the legislature’s chosen deterrent structure.

E. Why the majority rejected knowledge limited to the accident

Brown also argued that a driver must at least know an accident occurred before the statutory duty to stop can sensibly arise. The majority acknowledged that other states had adopted that reasoning, citing State v. Al-Naseer and Clancy v. State. It nevertheless considered Colorado’s statutory language and legislative intent controlling.

The majority identified an additional problem: Colorado generally applies a prescribed mental state to every element unless an intention to limit it clearly appears. Section 18-1-503(4) states that principle. Two decisions reinforced it:

• People v. Coleby applied “knowingly” throughout an offense despite its appearance in only one portion of the statute, because no legislative intent supported limiting it.
• People v. Trevino explained that the same general allocation rule applies to an implied mental state.

The majority found no sufficient textual or historical basis for requiring knowledge of the accident while excluding knowledge of the resulting death or injury. It therefore declined to construct that intermediate position.

Finally, the majority rejected Brown’s due-process challenge for substantially the same reasons. It viewed that challenge as depending on an interpretation of Rehaif v. United States that it had already rejected and directed concerns about inequitable applications to the legislature.

5. Justice Samour’s Separate Opinion: Scienter, Fairness, and Constitutional Limits

Justice Samour’s disagreement concerns the governing rule, not Brown’s ultimate entitlement to relief. His opinion argues that the majority gives insufficient weight to the presumption of scienter, constitutional limits on severe strict-liability punishment, and the practical possibility that a driver may genuinely be unaware of an accident.

A. The presumption of scienter and its foundational precedents

The separate opinion builds its analysis around several federal decisions:

• Morissette v. United States supplies the historical foundation: criminal liability ordinarily combines a wrongful act with a culpable mind. It also describes public-welfare offenses as commonly carrying relatively small penalties and limited reputational harm.
• United States v. X-Citement Video, Inc. supports applying scienter to distinguish wrongful conduct from otherwise innocent activity, even when the most grammatical reading of a statute points elsewhere.
• Staples v. United States provides the separate opinion’s principal analogy. The Supreme Court required knowledge of the characteristics bringing a weapon within a regulated category and refused to treat dangerousness and regulation alone as sufficient reasons to eliminate scienter.
• Rehaif v. United States, in Justice Samour’s reading, reaffirmed those principles and gave particular force to the distinction between minor regulatory penalties and harsh imprisonment.

The central disagreement is therefore not simply whether Rehaif v. United States formally overruled a state precedent. Justice Samour believed People v. Manzo was defective from the outset and that later developments made those defects more apparent.

He also invoked Schlup v. Delo and the concurrence in In re Winship for the criminal justice system’s foundational concern with avoiding convictions of innocent persons. These authorities serve as a normative foundation for his objection to severe punishment of drivers who lack awareness of the accident, rather than as direct holdings interpreting a leaving-the-scene statute.

B. Public-welfare offenses: a narrow exception, not a general safety label

Justice Samour traced the regulatory exception through United States v. U.S. Gypsum Co., United States v. Int'l Mins. & Chem. Corp., United States v. Dotterweich, and United States v. Balint. Those decisions concern limited settings in which dealings with dangerous substances or products can place a person on notice of heightened regulatory responsibilities.

United States v. Freed, involving unregistered grenades, illustrated the distinction. The defendant knew he possessed grenades; the omitted knowledge concerned registration. That is different, Justice Samour reasoned, from imposing punishment where the defendant lacks awareness of the event that creates the duty to act.

Liparota v. United States reinforced the concern about criminalizing apparently innocent activity. It required knowledge that food-stamp possession was unauthorized rather than treating a comprehensive regulatory scheme as enough to eliminate scienter.

Justice Samour read Staples v. United States as especially significant because it expressly discussed automobiles: the existence of vehicle regulation does not necessarily justify imprisonment for an unknown regulatory defect. He considered that reasoning incompatible with treating every driver as sufficiently on notice to justify a felony conviction for unknowingly leaving an accident.

He further challenged the five public-welfare considerations used in People v. Manzo: the omission of a required act, the risk of injury, interference with regulation, the absence of express intent language, and comparatively lower penalties. In his view, none overcame the basic problem that an unaware driver cannot perform a duty triggered by an unknown event.

People v. Ellison, quoted in the earlier decision for the public-safety importance of driving regulation, did not resolve that problem. Dangerousness and regulation, Justice Samour maintained, were insufficient under Staples v. United States. Likewise, Tenement House Dep't v. McDevitt, discussed through the federal authorities, illustrated the longstanding connection between reduced culpability and comparatively lenient regulatory punishment.

C. An implied mental state under Colorado law

Justice Samour relied on section 18-1-503(2), which permits implication of a culpable mental state for an offense or some of its material elements when the prohibited conduct necessarily involves that state. A duty to stop after an accident, he reasoned, necessarily presupposes awareness that the triggering accident occurred.

Brubaker v. Colo. Sun supported avoiding illogical or absurd statutory results. People v. Lee supported construing statutes to avoid serious doubts about their constitutionality. People v. Rostad supplied the broader concern about severe punishment without a culpable mental state and helped explain why intoxication-based vehicular offenses present a different issue: voluntarily consuming intoxicants and choosing to drive involves conscious conduct absent from the hypothetical unaware-driver case.

For the specific choice of “knowingly,” the separate opinion relied on:

• Randolph v. People and Gorman v. People, which support implying knowledge when a statute is silent and no clear reason favors another mental state;
• People v. Moore and People v. Bridges, examples of implying knowledge in particular criminal statutes; and
• People v. Lawrence, which likewise inferred knowledge where the statutory wording did not logically suggest specific intent, recklessness, or negligence.

The opinion notes that People v. Bridges was overruled in part on other grounds by People v. Jeffers, and that People v. Lawrence was abrogated on other grounds by Crawford v. Washington. Those later cases were cited to qualify the earlier authorities’ precedential status, not as independent support for the leaving-the-scene analysis.

Justice Samour’s proposed requirement was limited: knowledge of involvement in an accident of a type triggering a statutory duty to stop, not knowledge of the ultimate injury or death. He considered section 18-1-503(2) sufficient to permit that element-specific approach despite the majority’s reliance on section 18-1-503(4).

D. Competing lessons from legislative silence

Justice Samour disputed both pillars of the majority’s legislative analysis. First, testimony about discouraging flight assumes a driver knows an accident occurred; an unaware driver cannot respond to that incentive. Second, later amendments do not necessarily prove legislative approval of every aspect of a judicial interpretation.

His cited authorities developed that second point:

• People v. Jones, drawing on Patterson v. McLean Credit Union, cautioned against treating failure to amend a statute as affirmative legislative approval. The earlier interpretation at issue there came from People v. Lage.
• Star Athletica, L.L.C. v. Varsity Brands, Inc., quoting Pension Benefit Guar. Corp. v. LTV Corp., described legislative inaction as generally lacking persuasive significance.
• Alexander v. Sandoval warned against inferring approval from isolated amendments rather than a comprehensive statutory revision.
• United States v. Wells, quoting NLRB v. Plasterers' Loc. Union No. 79, cautioned against finding adoption of a controlling rule in legislative silence alone.
• Zuber v. Allen similarly characterized legislative silence as an unreliable guide to interpretation.

These authorities expose a genuine methodological tension: the majority treated amendment without correction as ratification, while Justice Samour treated that inference as too weak to overcome scienter and constitutional concerns.

E. Comparative leaving-the-scene precedents

The separate opinion’s extensive survey served two purposes: to demonstrate that accidents can occur without a driver’s awareness and to show that many courts imply knowledge in leaving-the-scene statutes. Those authorities are persuasive, not binding, in Colorado. Their statutory settings also differ, so they do not establish one uniform nationwide test.

Justice Samour’s claim that Colorado occupies an unusually isolated position is thus grounded in the cited comparative decisions. It remains a characterization advanced in the separate opinion, not a comprehensive nationwide factual determination independently made by the majority.

F. Knowledge can be proved without a confession

The separate opinion rejected the concern that requiring knowledge would make prosecution impracticable. State v. Nekolite, State v. Sidway, and People v. Wells recognize circumstantial proof of awareness. Cahours v. State, echoing State v. Miller, explains that knowledge and intent are commonly established through surrounding circumstances rather than direct evidence.

This is an important distinction: requiring actual awareness does not require the prosecution to produce an admission. Impact, vehicle damage, witnesses’ warnings, pauses, evasive conduct, and other facts may support an inference beyond a reasonable doubt.

G. Why Justice Samour nevertheless agreed with affirmance

Justice Samour considered the stare decisis exception satisfied under People v. Kembel and McShane v. Stirling Ranch Prop. Owners Ass'n. He viewed the earlier rule as both originally erroneous and increasingly unsound after greater penalties and further federal scienter decisions.

Even so, Brown’s circumstances did not present the unaware-driver problem. Brown paused, was told he had run over people, denied it, and drove away. Relying on the overwhelming-evidence approach illustrated by Pettigrew v. People, Justice Samour concluded that omitting a knowledge instruction was harmless beyond a reasonable doubt.

His further suggestion that courts should prohibit classifying felonies as public-welfare offenses absent a clear legislative statement was a proposed future rule. Neither the majority nor the court as a whole adopted it.

6. The Habitual-Offender Scheme: Constitutional Operation and Harmless Error

A. People v. Gregg defeats the facial challenge

The former scheme increased punishment where a defendant convicted of a felony had three qualifying previous convictions on charges separately brought and tried and arising from separate and distinct criminal episodes.

In People v. Gregg, the court had already rejected a facial challenge to a substantively equivalent statutory version. Although the statute assigned the judge responsibility for determining whether the defendant had been convicted as alleged, it did not expressly prohibit a jury from determining whether those convictions arose from separate criminal episodes.

The constitutionally permissible sequence was therefore:

1. The jury determines whether the relevant prior convictions arose from separate and distinct criminal episodes.
2. If it does, the judge reviews the finding for evidentiary sufficiency and enters the appropriate judgment.
3. If it does not, the court must acquit on the habitual-criminal counts.

Brown v. People applies that construction to the earlier statutory version governing Brown. The statute’s survival does not mean the judge-only procedure used in his case was necessarily proper. It means the statute could be administered consistently with the jury-trial requirement.

B. The omission was nonstructural

Brown argued that denying the jury determination required automatic reversal. The court disagreed, relying principally on People v. Crabtree, which treats omission of an element from jury consideration as nonstructural error subject to constitutional harmless-error review when preserved.

Two federal decisions reinforced that conclusion:

• Washington v. Recuenco holds that failure to submit a sentencing factor to the jury, like failure to submit an offense element, is not structural error.
• Neder v. United States distinguishes an omitted-element instruction from defects such as complete denial of counsel or trial before a biased judge. An omission does not necessarily make the entire proceeding fundamentally unfair or unreliable.

The issue was therefore not whether the jury right mattered, but whether the particular failure required reversal despite the evidence.

C. Why the record established harmlessness

The prosecution introduced records of six prior felony convictions: attempted theft and three forgeries in Colorado, and two vehicle-taking offenses in California. The records contained overlapping identifiers, including Brown’s name, birth date, physical description, photographs, identification numbers, and social security information, subject to an apparent typographical error in one file.

The files also reflected different plea, conviction, and sentencing dates spanning 1995 through 2008. On this particular record, the court considered the separate-and-distinct-episodes requirement indisputably established.

Bartley v. People supported the conclusion that overwhelming properly admitted evidence can establish constitutional harmlessness. The prosecution’s proof, the court held, satisfied that demanding standard.

This is a record-specific holding. The opinion should not be read to establish that different conviction or sentencing dates, standing alone, invariably prove distinct criminal episodes.

D. Authentication, old records, and possible reclassification

Brown challenged the reliability of the records because some original exhibits were lost, some convictions were decades old, and the California offenses might qualify for misdemeanor reclassification.

The court rejected those challenges:

• Certification: All but one file were triple certified, with reciprocal clerk and judge certifications and court seals. The remaining file was dual certified and contained sufficient authenticity markers.
• Historical authentication precedent: Brown v. People, 238 P.2d 847 (Colo. 1951), approved comparable triple-certified judgments as duly authenticated public records. This is a different case from the present litigation.
• Statutory evidentiary effect: Section 18-1.3-802 makes duly authenticated prior-conviction records prima facie evidence of the convictions.
• Age: The applicable pre-1998 record satisfied CRE 901(b)(8). Age alone did not undermine authenticity where the document’s condition and location supported it.
• California offenses: The court assumed without deciding that misdemeanor reclassification might be available. Even excluding those offenses, the four Colorado felonies exceeded the three-prior-conviction threshold.

The court therefore did not resolve the California reclassification question. Its conclusion rested on the independently sufficient Colorado convictions.

7. Potential Impact

A. Leaving-the-scene prosecutions

The immediate consequence is clear: Colorado prosecutors need not prove that a defendant knew an accident occurred to establish LTS (death) or LTS (SBI). Trial courts applying the decision should not add such a requirement to the elemental instructions.

Strict liability does not dispense with proof of the other statutory elements. The prosecution must still establish direct involvement, the relevant resulting harm, and failure to perform the statutory duties beyond a reasonable doubt. Nor does “directly involved” necessarily mean that the defendant caused the collision.

B. Severe penalties and future constitutional disputes

The majority declined to make punishment severity decisive. The separate opinion nevertheless identifies a substantial unresolved tension between severe imprisonment and liability without awareness of the triggering event.

Brown’s own evidence made that issue less outcome-determinative because his awareness was strongly supported. A future case involving genuine uncertainty about awareness could present the constitutional concern more sharply, although lower Colorado courts remain bound by this decision.

C. Legislative reform

The majority places responsibility for changing the statutory rule with the General Assembly. Possible reform could expressly require knowledge of the accident, distinguish accident awareness from awareness of resulting harm, or define a different culpability threshold.

Justice Samour’s discussion provides a framework for such legislation. His proposed distinction would preserve result-based felony grading while requiring awareness of the event that triggers the duty to stop.

D. Habitual-offender proceedings

The decision preserves challenges to the procedure used in an individual case even when a facial attack on the statute fails. It also confirms that denial of the required jury finding is not automatically reversible.

For prosecutors, the practical lesson is to present authenticated records that establish identity, qualifying convictions, and distinct criminal episodes. For defendants, a meaningful dispute about whether offenses arose from the same episode may be critical to defeating harmless-error treatment. The prosecution retains the burden of establishing harmlessness beyond a reasonable doubt.

8. Complex Concepts Simplified

Mens rea or scienter

A legally required mental state, such as knowledge or recklessness. Here, the dispute primarily concerned awareness of the accident, not knowledge of the law.

Strict liability

Liability without proof of a culpable mental state. The prosecution must still prove the offense’s remaining elements.

Public-welfare offense

A regulatory offense for which courts may sometimes interpret a statute as dispensing with ordinary mental-state requirements. The opinions disagree over whether serious leaving-the-scene felonies properly belong in that category.

Stare decisis

The principle that courts ordinarily follow earlier decisions. It promotes stability but permits departure under demanding conditions.

Dicta

Statements in an opinion that are unnecessary to its decision. The majority and Justice Samour disagreed about whether important language in Rehaif v. United States belonged in this category.

Facial versus as-applied challenge

A facial challenge attacks the statute itself; an as-applied challenge concerns its operation in a particular case. A statute may survive the former while a proceeding conducted under it remains constitutionally defective.

Structural error

A fundamental defect in the trial framework that generally requires reversal without asking whether it affected the outcome. The jury omission here was not classified as structural.

Constitutional harmless error

A constitutional trial error that does not justify reversal because the prosecution establishes harmlessness beyond a reasonable doubt.

Prima facie evidence

Evidence sufficient to establish a proposition unless adequately rebutted. It is not the same as conclusive proof.

9. Conclusion

Brown v. People leaves Colorado’s strict-liability rule for felony leaving-the-scene offenses intact despite increased penalties and a forceful separate opinion favoring an implied knowledge requirement. It also preserves the former habitual-offender statute through a constitutionally permissible jury-finding procedure and confirms that omission of that procedure can be harmless on an overwhelming record.

The decision’s broader significance lies in its competing approaches to criminal responsibility: the majority emphasizes precedent, legislative acceptance, and deterrence; Justice Samour emphasizes scienter, individual awareness, and constitutional limits on severe punishment. The judgment is settled for Brown, but that underlying debate remains important for future litigation and legislative reform.
