    ASSOCIATE CHIEF JUSTICE LEE, opinion of the Court:
    ¶1 Manuel Antonio Lujan was convicted of aggravated robbery
    based on eyewitness identification testimony and other evidence
    admitted at trial. The court of appeals reversed the conviction under
    STATE v. LUJAN
    Opinion of the Court
    the “reliability” factors set forth in State v. Ramirez, 
    817 P.2d 774
    (Utah 1991). State v. Lujan, 
    2015 UT App 199
    , 
    357 P.3d 20
    . Ramirez
    identified five factors for courts to consider in assessing the
    reliability (and hence admissibility) of eyewitness identification
    testimony under the due process clause of the Utah Constitution: (1)
    the “opportunity” of the eyewitness to view the suspect; (2) the
    degree of attention paid to the suspect; (3) the witness’s capacity to
    observe the event; (4) the degree of “spontane[it]y” and
    “consisten[cy]” of the eyewitness testimony; and (5) “the nature of
    the event being observed.” 817 P.2d at 781 (citation omitted).
    Applying these factors, the court of appeals concluded that the
    testimony in question was “legally insufficient . . . to warrant a
    preliminary finding of reliability and, therefore, admissibility.”
    Lujan, 
    2015 UT App 199
    , ¶ 15 (quoting Ramirez, 817 P.2d at 784). And
    it reversed on the ground that the State had not carried its burden of
    establishing    that    “the    improperly     admitted     eyewitness
    identifications were harmless beyond a reasonable doubt.” Id. ¶ 16.
    ¶2 In so doing, however, the court of appeals also raised
    concerns about the viability of the standard set forth in Ramirez. In
    light of developments in “scientific and legal research regarding the
    reliability of eyewitness identification[]” testimony since our
    decision in Ramirez, the majority indicated that it had “every reason
    to believe” that the Ramirez framework “must be revisited” by this
    court. Id. ¶ 10 n.1. Then-Judge Pearce dissented but echoed the view
    “that the time may have arrived for the Utah Supreme Court to
    revisit its holding” in Ramirez. Id. ¶ 21 (Pearce, J., dissenting).
    ¶3 We granted certiorari in light of the court of appeals’ open
    call for our reconsideration of Ramirez. And in the course of our
    consideration of this case a number of developments have ensued.
    We asked for supplemental briefing on the question of whether and
    to what extent the Ramirez factors set a freestanding guarantee of
    evidentiary reliability rooted in the Utah Constitution. We then
    reheard the case after a member of the court retired while the matter
    was under advisement. And in the meantime our court considered
    and promulgated a new rule of evidence governing the admissibility
    of eyewitness identification testimony. See UTAH R. EVID. 617
    (effective November 1, 2019).
    ¶4 These developments have informed our consideration of the
    important questions presented in this case. In light of them we now
    take up the court of appeals’ request that we revisit the factors set
    forth in our decision in Ramirez. And we do so first by specifying the
    “order of operations” in assessing the reliability and admissibility of
    eyewitness identification testimony. We clarify that the threshold
    2

    2020 UT 5
    Opinion of the Court
    step in this assessment is a matter for our rules of evidence. We hold
    that those rules, including (in cases going forward) new rule 617 of
    the Utah Rules of Evidence, prescribe the factors that trial courts
    should consider in judging the reliability and admissibility of
    eyewitness identification evidence. And we note that our established
    rulemaking process lends itself nicely to adaptation over time in
    response to developments in scientific and legal scholarship in this
    important field.
    ¶5 We also contrast our adaptive rulemaking process with our
    settled method of constitutional interpretation. Our recent cases have
    clarified our carefully circumscribed role in interpreting the
    constitution. We have emphasized that the provisions of this charter
    document are not a license for common-law policymaking1 but
    instead a fixed set of limits on the operation of our government. Such
    limits are interpreted in accordance with the public understanding of
    the constitution when it was originally established.2 And these
    premises highlight a key limitation on the factors set forth in our
    Ramirez decision—the fact that the Ramirez court spoke vaguely of
    advancing constitutional “due process” interests but nowhere rooted
    the factors we adopted in the text or original understanding of the
    Utah Constitution. There is some tension and confusion in our case
    law on the question whether the Ramirez factors are mandated as a

    the due process clause of the Utah Constitution is not a

    3
    STATE v. LUJAN
    Opinion of the Court
    matter of state constitutional law.3 But it is clear that we have never
    identified a basis for these factors in the interpretive methodology
    that governs our approach to questions of state constitutional law—
    the original public meaning of the due process clause of the Utah
    Constitution. And that shortcoming is sufficient for us now to
    reinforce a point we alluded to in our decision in State v. Hubbard,
    which is that the Ramirez factors themselves are not rooted in
    constitutional soil. See 
    2002 UT 45
    , ¶ 27, 
    48 P.3d 953
     (the Ramirez
    factors “provide guidance” but are not “exhaustive or exclusive”
    considerations in determining whether identifications are “violative
    of due process”).
    ¶6 We revisit and clarify Ramirez on this basis. We endorse the
    need for revising and updating the factors set forth in that opinion.
    But we emphasize that the revising and updating is done as a matter
    of our revisions to the Utah Rules of Evidence, and not by treating
    the Utah Constitution as a vessel for judicial policymaking.
    ¶7 This is not to say that there is no role for the due process
    clause in a case like this one. Our decisions in Ramirez and Hubbard
    also reinforced a premise established under the federal Due Process
    Clause in binding precedent of the United States Supreme Court.
    That premise is that eyewitness identification evidence may be
    excluded if it is produced as a result of suggestive police activity and
    the taint of suggestive police procedures creates a “substantial
    likelihood of misidentification.” Neil v. Biggers, 
    409 U.S. 188
    , 201
    (1972); see also Ramirez, 817 P.2d at 784 (considering reliability in the
    context of a “blatant[ly] suggestive[]” showup); Hubbard, 
    2002 UT 45
    ,
    ¶¶ 23, 26 (examining whether “procedural actions taken by [police]”
    are so “impermissibly suggestive” as to create a “substantial
    likelihood of irreparable misidentification” under both the federal
    and state due process clauses). We endorse and reaffirm that
    principle here, which controls as a matter of stare decisis. But we
    clarify that in the face of suggestive police activity the due process
    standard is still only a constitutional backstop to the threshold
    inquiry into reliability and admissibility under our rules of evidence.

    Opinion of the Court
    And we emphasize that that threshold inquiry under our rules may
    render the constitutional inquiry unnecessary in many cases.
    ¶8 We thus reverse the court of appeals on the ground that the
    legal framework it established (and, indeed, the one it invited us to
    reconsider) is no longer viable. Because we have substantially
    reformed the law in this field, we might, in an ordinary case, be
    inclined to remand to the district court to allow it to apply our new
    standards to the facts of this case in the first instance. We see no need
    to do so here, however. Instead we reinstate the jury verdict on an
    alternative basis advanced by the State—on the ground that any
    arguable error in admitting the eyewitness identification evidence in
    this case was harmless in light of the other evidence in the record
    establishing Manuel Lujan’s guilt.
    I
    ¶9 Early in the morning before sunrise on November 25, 2012, a
    man went out to get his car ready for an upcoming annual
    inspection. When he sat down in the driver’s seat he noticed that the
    car’s dome light was on and that someone had opened the rear
    driver’s side door. Then he saw a man who was later identified as
    Manuel Lujan, who closed the rear door and opened the driver’s
    door. Lujan squatted next to the driver’s seat with his face about
    eight to nine inches from the man’s face and asked, “why you
    following me?” Lujan then stood up, opened his jacket, and reached
    near his waist for what the man thought was a knife or gun. The man
    decided to retreat to the house, fearing he might be stabbed or shot.
    ¶10 At that point the man stood up, placing himself at eye level
    with Lujan and within such close proximity that the men were
    “almost touching.” The man then slowly moved towards the house,
    maintaining visual contact with Lujan the entire time. Lujan
    followed the man, moving into the light of the car’s headlights. Once
    inside, the man turned on the floodlights, locked his door, and woke
    up his younger brother. The two stepped outside the house in time
    to see Lujan drive the car off the property. And the man’s brother
    quickly called the police, who responded shortly thereafter.
    ¶11 The man’s encounter with Lujan occurred before sunrise.
    But there were streetlights on across the street, the man’s porch light
    was on, and the car’s headlights and dome light remained on
    throughout the encounter.
    ¶12 When the police arrived at the man’s house, the man gave a
    description of the robber. He stated that the robber was about 5’10”,
    180 pounds, “Spanish,” wearing a black jacket, and had “‘longish
    5
    STATE v. LUJAN
    Opinion of the Court
    hair’ [that] poked out of [a] beanie to ‘mid-ear length.’” While the
    man was giving his statement, the police officer noticed a trail of
    liquid on the ground from where the car had been parked and
    leading north out of the driveway. The officer cut the interview short
    to follow the trail of liquid. He found the car abandoned a few blocks
    away near an elementary school. The officer then had additional
    officers set up a containment area and called for a K-9 unit to help
    him search for the culprit.
    ¶13 One of the officers participating in the safety sweep around
    the school heard a noise sounding like someone climbing a chain
    link fence near the classrooms. The officer followed the noise and
    found Lujan “curled into a ball” next to a fenced-off air conditioning
    unit outside one of the classrooms. When the officer asked Lujan
    why he was hiding, Lujan responded “somebody is following me.”
    The officer described Lujan as a Hispanic man with closely shaven
    hair and a goatee, wearing a black beanie and a black jacket.
    ¶14 Approximately thirty minutes after the robbery, an officer
    transported the man to the site where the police had found Lujan.
    Lujan was the only non-police officer in the area, was in handcuffs,
    and was illuminated with police spotlights. The police asked the
    man if he could identify the robber. And he identified Lujan as the
    same person who had accosted him and stolen his car.
    ¶15 Lujan was charged with first-degree-felony aggravated
    robbery. A few months later, the defense requested a lineup
    identification procedure. The man identified two possible
    perpetrators in the lineup—Lujan and another person who “looked
    familiar.” The man again identified Lujan as the robber at the
    preliminary hearing. After the preliminary hearing, Lujan moved to
    suppress the in-court identification as well as evidence that the man
    had identified Lujan in the showup. The court denied his motion and
    permitted the man to identify Lujan at trial as the person who
    robbed him. At trial, the defense called an expert to testify about the
    reliability of eyewitness identification. But the jury ultimately
    convicted Lujan for aggravated robbery.
    ¶16 Lujan appealed. The court of appeals reversed and vacated
    Lujan’s conviction, remanding for a new trial. It concluded that the
    eyewitness identification testimony was not reliable, and thus
    inadmissible, under the reliability factors laid out in State v. Ramirez,
    
    817 P.2d 774
     (Utah 1991). State v. Lujan, 
    2015 UT App 199
    , ¶ 19, 
    357 P.3d 20
    . Yet it also openly called on this court to revisit the Ramirez
    factors, asserting that Ramirez was an “unreliable tool” and stating
    that the “scientific and legal research regarding the reliability of
    6
    Cite as: 
    2020 UT 5
    Opinion of the Court
    eyewitness identifications has progressed significantly in the last
    twenty-four years.” 
    Id.
     ¶ 10 n.1.
    ¶17 Then-Judge Pearce dissented. He “agree[d] with the
    majority that the time may have arrived for the Utah Supreme Court
    to revisit its holding” in Ramirez. Id. ¶ 21 (Pearce, J., dissenting). Yet
    he also noted that the court of appeals was “duty-bound to apply”
    the Ramirez standard so long as it stands as precedent. Id. And he
    proceeded to disagree with the majority’s conclusion in applying
    Ramirez to the facts of this case. Id. Judge Pearce concluded that “the
    showup involving Defendant in this case was substantially less
    troublesome than that the Ramirez court approved.” Id. And he
    accordingly indicated that he would have affirmed Lujan’s
    conviction. Id. ¶ 31.
    ¶18 We granted certiorari. We review the court of appeals’
    decision de novo, affording no deference to its analysis of the
    important legal questions presented.
    II
    ¶19 The court of appeals has invited us to reconsider and revise
    the standards of evidentiary reliability set forth in our decision in
    Ramirez. And understandably so, as the scientific and legal
    scholarship in this field has evolved substantially since the time of
    our decision in that case—in a manner raising serious questions
    about the continuing viability of the factors we prescribed in the
    Ramirez decision. See State v. Clopten, 
    2015 UT 82
    , ¶ 53, 
    362 P.3d 1216
    (noting that “eyewitness memory science” relied upon in prior
    precedent had “already been called into question by subsequent
    research”). We granted certiorari to take up the court of appeals’
    challenge. And in the course of the briefing and argument we also
    uncovered a key point of conflict or imprecision in our case law in
    this field. The imprecision concerns the legal basis for the factors
    prescribed in our Ramirez opinion.
    ¶20 On one hand, we have sometimes suggested that the
    Ramirez factors are rooted in constitutional soil. See, e.g., State v.
    Ramirez, 
    817 P.2d 774
    , 778 (Utah 1991); State v. Guzman, 
    2006 UT 12
    ,
    ¶ 21, 
    133 P.3d 363
    ; State v. Hubbard, 
    2002 UT 45
    , ¶ 25, 
    48 P.3d 953
    . In
    the Ramirez case itself, for example, we spoke of a “required
    constitutional admissibility analysis” for eyewitness identification
    testimony. 817 P.2d at 778. And when we articulated factors for
    judging reliability and admissibility of such testimony, we spoke of
    the matter as presenting a “constitutional” question. Id. at 780–81.
    7
    STATE v. LUJAN
    Opinion of the Court
    ¶21 Lujan has advanced this view of the Ramirez factors in his
    briefing in this case. Citing Ramirez and other decisions, Lujan has
    urged us to reinforce the factors that we prescribed in Ramirez. And
    he asks us to treat them as establishing a threshold standard of
    evidentiary reliability that a court should use in “fulfilling its charge
    as [a] gatekeeper . . . [for] eyewitness identification.” Lujan asserts
    that this standard is guaranteed by the due process clause of our
    Utah Constitution.
    ¶22 The State urges a contrary view. It asks us to “free the
    [Ramirez] factors of a constitutional foundation” and instead
    establish that the threshold standard of reliability and admissibility
    of evidence is a matter for our rules of evidence. It maintains that
    keeping up with “current research” is best “accomplished through
    evidentiary means” given the “fast-changing dynamics” of the field.
    ¶23 This position also finds some support in our case law—and,
    as the State notes, in recent authority from the United States
    Supreme Court. In Hubbard we stated that the factors set forth in
    Ramirez “provide guidance” on the reliability of eyewitness
    identification testimony but suggested that the list is not “an
    exhaustive or exclusive list of factors that may be considered in
    determining whether an identification is reliable.” 
    2002 UT 45
    , ¶ 27.
    Our cases, moreover, have never proffered the Ramirez factors as a
    freestanding standard of evidentiary admissibility. Instead, as the
    State notes in its briefing, almost every case4 in which we have
    applied the Ramirez factors has involved a threshold showing of state
    action in the form of suggestive police activity.5 This implicates a key

    4 Hubbard is the one case in which we applied the Ramirez factors
    in the absence of suggestive police activity. 
    2002 UT 45
    , ¶ 26. But as
    noted above, we made clear in that case that we did not consider
    their application constitutionally required. Id. ¶ 27; see also infra
    ¶¶ 26–28.

    identification following a one-person showup arranged by police);

    Opinion of the Court
    question on which we requested supplemental briefing in this case:
    whether the Utah due process clause establishes a freestanding
    guarantee of evidentiary reliability or instead just comes into play in
    the face of suggestive police activity.
    ¶24 The State points us to recent authority from the United
    States Supreme Court on this question—Perry v. New Hampshire, 
    565 U.S. 228
     (2012). The Perry Court held that the threshold inquiry for
    admissibility of eyewitness identification testimony is a matter for
    “statutes and rules . . . govern[ing] the admissibility of evidence.” 
    Id. at 237
    . It also stated that “due process concerns arise only when law
    enforcement officers use an identification procedure that is both
    suggestive and unnecessary.” 
    Id.
     at 238–39. “Even when the police
    use such a procedure,” the Perry Court held that “suppression of the
    resulting identification is not the inevitable consequence.” 
    Id. at 239
    .
    “Instead of mandating a per se exclusionary rule, . . . the Due Process
    Clause requires courts to assess, on a case-by-case basis, whether
    improper police conduct created a substantial likelihood of
    misidentification.” 
    Id.
     (citation and internal quotation marks
    omitted). “The due process check for reliability” of eyewitness
    identification testimony, in other words, “comes into play only after
    the defendant establishes improper police conduct.” 
    Id. at 241
    .
    ¶25 We need not and do not decide whether to endorse the Perry
    framework as a matter of the law of due process under the Utah
    Constitution. In this case the State has not challenged the allegation
    of suggestive police activity. And for that reason we need not decide
    the broader question whether the Utah due process clause
    establishes a freestanding guarantee of the reliability of eyewitness
    identification testimony that would attach in the absence of state
    action in the form of suggestive police activity.
    ¶26 That still leaves the question whether, in a case involving
    suggestive police activity, the Ramirez factors themselves are
    mandated by the Utah Constitution. We hereby hold that they are
    not so mandated. We suggested as much in our decision in Hubbard.
    
    2002 UT 45
    , ¶ 27. And, importantly, Lujan has proffered no basis for
    a determination that the Ramirez factors would have been
    understood by the public as an element of the guarantee of “due
    process of law” at the time of the ratification of the Utah
    _____________________________________________________________

    a photo array arranged by police).

    STATE v. LUJAN
    Opinion of the Court
    Constitution. This is a fatal deficiency under our case law. We have
    repeatedly reinforced the notion that the Utah Constitution is to be
    interpreted in accordance with the original public meaning of its
    terms at the time of its ratification. See South Salt Lake City v. Maese,
    
    2019 UT 58
    , ¶ 18, 
    450 P.3d 1092
    ; Zimmerman v. Univ. of Utah, 
    2018 UT 1
    , ¶ 25, 
    417 P.3d 78
    ; Neese v. Utah Bd. of Pardons & Parole, 
    2017 UT 89
    ,
    ¶ 96, 
    416 P.3d 663
    . And we have emphasized that it is this mode of
    analysis that controls. The due process clause of the Utah
    Constitution is not a “free-wheeling constitutional license” for this
    court to “assure fairness on a case-by-case basis.” In re Steffensen,
    
    2016 UT 18
    , ¶ 7, 
    373 P.3d 186
    . It is a guarantee of procedural rights
    “measured by reference to traditional notions of fair play and
    substantial justice.” 
    Id.
     (citation and internal quotation marks
    omitted). And Lujan has not established a basis for the conclusion
    that the “traditional notions” of due process rooted in the original
    public meaning of the Utah Constitution would sustain a decision to
    chisel the Ramirez factors into constitutional stone.
    ¶27 Nor can we find any such basis in our opinion in Ramirez.
    The Ramirez opinion looked only to evolving social science in its
    articulation of the reliability factors that it identified. It based the
    factors on “well-respected and essentially unchallenged empirical
    studies” as laid out in State v. Long, 
    721 P.2d 483
     (Utah 1986), even
    while conceding that the holding in Long “was not squarely based on
    the state constitution.” Ramirez, 817 P.2d at 780. The opinion
    established this “more empirically based approach” solely because
    the court “judge[d] this to be a more appropriate approach.” Id.
    ¶28 These sorts of considerations—rooted in evolving social
    science and legal scholarship—may be appropriate grounds for our
    provision of “guidance” on the reliability of eyewitness
    identification testimony. See Hubbard, 
    2002 UT 45
    , ¶ 27. But such
    evolving grounds are not a basis for establishing fixed principles of
    constitutional law. And our decision in Ramirez nowhere offered an
    originalist basis for constitutionalizing the reliability factors set forth
    in that opinion.
    ¶29 We reinforce that understanding of Ramirez here. In so
    doing we reverse the decision of the court of appeals, which applied
    the factors set forth in the Ramirez opinion as the threshold basis for
    assessing the admissibility of the eyewitness identification testimony
    10
    Cite as: 
    2020 UT 5
    Opinion of the Court
    in this case.6 We thus clarify that the threshold legal framework for
    judging the admissibility of eyewitness identification testimony is
    established under our rules of evidence. Those rules, importantly,
    have the virtue of being subject to nimble reformulation and revision
    in response to changes in prevailing scientific and legal scholarship
    of relevance to the reliability of eyewitness identification testimony.
    See Clopten, 
    2015 UT 82
    , ¶ 80 (Lee, A.C.J., concurring) (explaining
    that concerns about our eyewitness identification testimony law “can
    and should be dealt with by an amendment to our rules of evidence”
    and noting the “many virtues of that system” in contrast to having
    judges “make rules of evidence on the fly based on evolving social
    science”).
    ¶30 And we note that our rulemaking process has in fact
    fulfilled this task. Even while this case was under advisement, our
    advisory committee on the Utah Rules of Evidence considered and
    proposed a new rule of evidence governing the admissibility of
    eyewitness identification testimony—rule 617. This rule draws on
    recent scholarship in social science journals and law journals of
    relevance to the reliability of eyewitness identification testimony.
    And it establishes factors and standards for a trial court to employ in
    judging the admissibility of eyewitness testimony.
    ¶31 This new rule, of course, was not in place at the time of the
    trial in this proceeding. So it could not have been applied in the
    disposition of this case. But other rules of evidence were in place at
    the time of the trial court proceedings, and those rules could and
    should have been applied in assessing Lujan’s challenge to the
    admissibility of the eyewitness identification testimony in this case.
    ¶32 The governing rules of evidence were not the basis for the
    lower court decisions before us on certiorari in this case. And in the
    absence of a lower court decision applying the governing law as now
    _____________________________________________________________
    6 This is, of course, no knock on the court of appeals. That court
    was bound to follow our case law as it stood in place at the time of
    the decision before us on certiorari review. And our precedent was
    plausibly read as establishing the Ramirez factors as a freestanding,
    constitutionally mandated standard for judging the admissibility of
    eyewitness identification testimony. So although we reverse the
    court of appeals, the judges of that court are to be applauded for a
    decision that helpfully cued up an important question for our
    review—and that prompted a reformulation of precedent that is only
    ours to make.
    11
    STATE v. LUJAN
    Opinion of the Court
    clarified by this court, we might ordinarily remand the case for
    reconsideration in light of the newly revised standard. We see no
    need to do so here, however, because we affirm the verdict in the
    trial court on an alternative basis advanced by the State. We hold
    that any arguable error in the admission of the eyewitness testimony
    in this case was harmless beyond a reasonable doubt in light of the
    substantial evidence connecting Lujan to the crime even absent the
    testimony of the eyewitness.
    ¶33 In the paragraphs below we first highlight the standards in
    our rules of evidence (both at the time of trial and under newly
    adopted rule 617) that should have formed the basis for the
    threshold inquiry into the admissibility of the eyewitness testimony
    in this case. Second, we clarify the remaining role for due process in
    a case involving suggestive police activity—a constitutional backstop
    for the reliability standards set forth in our rules of evidence. And
    finally, we conclude by explaining the basis for our decision to
    affirm the trial verdict without any need for a remand under the
    framework as clarified in this decision.
    A
    ¶34 Our rules of evidence include several tools for assessing the
    reliability and admissibility of eyewitness identification testimony.
    And importantly, these tools leave room for consideration of, and
    adaptation based on, developments in scholarly literature in this
    field.
    ¶35 A key question for admissibility under the rules in place at
    the time of the trial in this case arises under rule 403. That rule
    provides that “[t]he court may exclude relevant evidence if its
    probative value is substantially outweighed by a danger of” (among
    other things) “unfair prejudice.” UTAH R. EVID. 403.
    ¶36 The threshold inquiry under rule 403 goes to the probative
    value of the testimony of a given eyewitness. Where there is an
    eyewitness to a crime, his testimony typically will have at least some
    probative value. Yet developments in the scholarly literature have
    uncovered some grounds for questioning the strength or reliability
    of such evidence. Important research has identified both “estimator
    variables” and “system variables” that may tend to undermine the
    reliability of a given eyewitness account. See MASSACHUSETTS
    SUPREME JUDICIAL COURT STUDY GROUP ON EYEWITNESS EVIDENCE,
    REPORT AND RECOMMENDATIONS TO THE JUSTICES (2013); State v.
    Henderson, 
    27 A.3d 872
     (N.J. 2011). And these variables may be
    considered in assessing both the probative value of a given piece of
    12
    Cite as: 
    2020 UT 5
    Opinion of the Court
    eyewitness identification testimony and the possibility of it
    producing unfair prejudice.
    ¶37 Estimator variables are factors connected to the event,
    witness, or perpetrator—items over which the justice system has no
    control. See Henderson, 27 A.3d at 895. These are factors that may
    affect the reliability of an eyewitness account. They include (among
    others) the viewing conditions at the time of the event (distance,
    lighting, etc.), the amount of stress (or duress) the witness was
    under, whether there was a weapon that the witness focused on,
    witness characteristics (age, impairment, etc.), perpetrator
    characteristics (like age and race, given that witnesses are better at
    identifying persons of their own age and race), and factors affecting
    memory decay. Id. at 904–10.
    ¶38 System variables consist of factors controlled by the court or
    law enforcement. See id. at 895–96. Examples of system variables that
    may affect the reliability of an eyewitness account are the use of
    double-blind     identification   procedures,    the    quality    of
    pre-identification instructions, and the use of proper lineup
    construction. See id. at 896–903.
    ¶39 These lists are exemplary. The cited sources list other
    estimator and system variables. And research in this field is
    ongoing—over time we are understanding better and better how
    human perception and recall work when it comes to eyewitness
    identification. But the core point is this: The perception and memory
    of an eyewitness account may be affected by a wide range of factors
    not intuitively obvious to a juror (or even a judge), and careful
    consideration of these factors is important in assessing the reliability
    or probative value of eyewitness testimony. See Nicholas A.
    Kanh-Fogel, The Promises and Pitfalls of State Eyewitness Identification
    Reforms, 104 KY. L.J. 99, 124 (2016).
    ¶40 Our rulemaking process is set up in a manner that enables
    us to react nimbly to further developments in this field. And as our
    understanding of the factors that affect the reliability of eyewitness
    testimony develops, our application and understanding of our rules
    of evidence can likewise evolve.
    ¶41 The above-listed factors are crucial to the assessment of
    unfair prejudice. Eyewitness testimony is common. And it is
    sometimes viewed as the gold standard. It is tempting to say that
    “there is almost nothing more convincing . . . than a live human
    being who takes the stand, points a finger at the defendant, and says
    ‘That’s the one!’” Henderson, 27 A.3d at 889 (citation and emphasis
    omitted). But some eyewitness accounts are fool’s gold. An
    13
    STATE v. LUJAN
    Opinion of the Court
    eyewitness who is affected by significant estimator or system
    variables may appear to present a highly probative account of the
    crime; but false appearance of probity may ultimately translate into
    unfair prejudice. Cf. State v. Maestas, 
    1999 UT 32
    , ¶ 26, 
    984 P.2d 376
    (“[B]ecause jurors do not appreciate the fallibility of [eyewitness]
    identifications, they often give eyewitness testimony undue
    weight.”).
    ¶42 The above-noted estimator and system variables also
    informed our advisory committee’s proposal that we adopt a new
    rule of evidence aimed specifically at eyewitness identification
    testimony. New rule 617 first identifies nine nonexclusive factors
    (based on “estimator variables” identified in the literature) for a
    judge to use in assessing the reliability and thus admissibility of
    eyewitness identification evidence: (1) “opportunity to observe the
    suspect committing the crime”; (2) impaired attention caused by a
    weapon or other distraction; (3) physical and mental capacity to
    make an observation; (4) awareness that a crime was taking place
    and resulting effect on a witness’s ability to “perceive, remember,
    and relate it correctly”; (5) cross-racial identification; (6) length of
    time between the original observation and identification;
    (7) instances of identification or failure to identify a suspect, and
    later consistency; (8) exposure to opinions, photographs, or other
    information influencing the independence of the identification; and
    (9) “any other aspect of the identification” affecting reliability. UTAH
    R. EVID. 617(b). Under rule 617(b), the court is to exclude eyewitness
    identification evidence if the party challenging the evidence “shows
    that a factfinder . . . could not reasonably rely on the eyewitness
    identification.” 
    Id.
    ¶43 Rule 617 also incorporates “system variables.” These
    variables are incorporated by the rule in its identification of factors
    relevant to determining whether a photo array, lineup, or showup
    was “unnecessarily suggestive.” Id. 617(c). If an identification
    procedure is “contested,” the court is to “determine whether the
    identification procedure was unnecessarily suggestive or conducive
    to mistaken identification” based on the system and estimator
    variables set forth in the rule. Id. “If so, the eyewitness identification
    must be excluded unless the court, considering” both estimator and
    system variables, “finds that there is not a substantial likelihood of
    misidentification.” Id.
    ¶44 By taking account of both the “estimator variables” and
    “system variables” that have been identified in scholarly literature,
    rule 617 thus allows a trial judge to more effectively assess whether
    such variables have undermined the reliability of a given eyewitness
    14
    Cite as: 
    2020 UT 5
    Opinion of the Court
    account. In light of the evolving nature of academic discourse on this
    subject, however, the rule does not paint courts into a corner. Rule
    617 makes clear that the factors it identifies to account for estimator
    and system variables are nonexhaustive: “As scientific research
    advances, other factors in addition to those outlined . . . may be
    considered” by judges in performing their gatekeeping function. 
    Id.
    617 advisory committee notes.
    ¶45 A threshold focus on the rules of evidence furthers the
    principle of constitutional avoidance—by frontloading the question
    of admissibility under our rules of evidence in advance of any
    constitutional inquiry. And it yields the kind of flexibility called for
    by the court of appeals in its decision below and by the parties in
    their briefing. See State v. Lujan, 
    2015 UT App 199
    , ¶ 10 n.1, 
    357 P.3d 20
     (referring to developments in “scientific and legal research
    regarding the reliability of eyewitness identification[]” testimony
    over the years since our decision in Ramirez and suggesting that the
    Ramirez framework “must be revisited” by this court); see also
    Clopten, 
    2015 UT 82
    , ¶ 80, 
    362 P.3d 1216
     (Lee, A.C.J., concurring) (the
    evolution of eyewitness identification science “can and should be
    dealt with by an amendment to our rules of evidence”).
    B
    ¶46 While the threshold standard of admissibility of eyewitness
    testimony is provided by the Utah Rules of Evidence, the governing
    case law also preserves a role for due process. When eyewitness
    identification evidence is secured by “unnecessarily suggestive”
    police action, the federal Due Process Clause adds a constitutional
    backstop to our rules of evidence. Perry v. New Hampshire, 
    565 U.S. 228
    , 235 (2012). And our case law has established a similar backstop
    under the due process clause of the Utah Constitution. See, e.g., State
    v. Ramirez, 
    817 P.2d 774
    , 779, 784 (Utah 1991); State v. Hubbard, 
    2002 UT 45
    , ¶¶ 25–26, 
    48 P.3d 953
    .
    ¶47 The backstop test under federal law bars eyewitness
    evidence if the taint of suggestive police procedures created a
    “substantial likelihood of misidentification.” Neil v. Biggers, 
    409 U.S. 188
    , 201 (1972). In assessing that likelihood, the court is to weigh the
    “indicia of reliability” against the “corrupting effect of the
    police-arranged suggestive circumstances.” Perry, 
    565 U.S. at 232
    .
    ¶48 The Supreme Court has identified factors to consider in that
    assessment. These factors include: “the opportunity of the witness to
    view the criminal at the time of the crime, the witness’ degree of
    attention, the accuracy of his prior description of the criminal, the
    level of certainty demonstrated at the confrontation, and the time
    15
    STATE v. LUJAN
    Opinion of the Court
    between the crime and the confrontation.” 
    Id.
     at 239 n.5 (citation
    omitted). These factors are to be applied in assessing “on a case-by-
    case basis[] whether improper police conduct created a ‘substantial
    likelihood of misidentification.’” 
    Id. at 239
     (quoting Biggers, 
    409 U.S. at 201
    ). Where the court finds such a likelihood in light of the
    “totality of the circumstances,” due process requires the exclusion of
    the evidence. 
    Id.
    ¶49 While this court did expand on the Supreme Court’s
    “factors” in Ramirez—with factors that we deemed to “more
    precisely define the focus of the relevant [due process] inquiry,” 817
    P.2d at 781—these factors are not constitutionally required because
    they are not rooted in the text or original understanding of the Utah
    Constitution. See supra ¶¶ 26–28. We reinforce that holding here. But
    we nonetheless preserve the standards set forth in Ramirez as a
    matter of stare decisis as clarified above. Thus, we hold that the
    Ramirez factors are entitled to stare decisis respect, and will not be
    overridden, insofar as they provide “guidance” of relevance to the
    purpose for which they have been applied in our case law—as
    possible considerations in assessing whether evidence produced as a
    result of suggestive police activity should be excluded on the ground
    that it leads to a substantial likelihood of misidentification. But
    unless and until the framework for a backstop due process test is
    rooted in the original meaning of the Utah due process clause, these
    factors remain just that—guidance, rather than a constitutionally
    required test.7
    _____________________________________________________________
    7 In so holding we do not rule out the possibility of a
    determination, in a future case in which the question is squarely
    presented, that state constitutional standards under the Utah due
    process clause differ from federal due process standards under Neil
    v. Biggers, 
    409 U.S. 188
    , 201 (1972). See Alpine Homes, Inc. v. City of
    West Jordan, 
    2017 UT 45

    424 P.3d 95
     (explaining that even
    where “the Utah clause is similar to the federal clause, we do not
    presume that federal court interpretations of federal Constitutional
    provisions control the meaning of identical provisions in the Utah
    Constitution” (citation and internal quotation marks omitted));

    Opinion of the Court
    ¶50 In so stating we reinforce points we have made throughout
    this opinion. We endorse the need for ongoing adjustment and
    refinement of the standards of reliability and admissibility of
    eyewitness identification testimony in response to scholarly
    developments in this field. Yet we emphasize that the principal,
    threshold basis for such adjustment and refinement is through
    amendments to our rules of evidence.
    ¶51 We also emphasize the predominant role for our rules of
    evidence in the run of cases. The standard for admissibility under
    our rules of evidence is, if anything, more protective than the
    constitutional due process standard. Cf. Ramirez, 817 P.2d at 784
    (declining to engage in “separate Biggers federal analysis” in light of
    the court’s conclusion that the state due process clause “is certainly
    as stringent as, if not more stringent than, the federal analysis”).
    Specifically, the estimator and system variables that have been
    incorporated into rule 617, and could be considered under rule 403,
    encompass all of the factors relevant to the due process inquiry (and
    more). It seems likely that whenever there is a “substantial
    likelihood of misidentification” under the due process framework
    there will also be a basis for exclusion under our rules of evidence.
    And this will allow our courts to avoid the constitutional inquiry in
    the run of cases, and to keep the focus on the standards of
    admissibility under our rules of evidence.

    due process in our formulation of state due process standards. And
    we may thus depart from the federal formulation if and when we are
    presented with state constitutional analysis rooted in the original
    meaning of the Utah due process clause. See South Salt Lake City v.

    17
    STATE v. LUJAN
    Opinion of the Court
    C
    ¶52 We have clarified and reformulated the framework for the
    analysis of the admissibility of eyewitness identification testimony in
    Utah. Ordinarily that might call for a remand to allow a lower court
    to apply our revised legal standard to the facts of this case in the first
    instance. We see no need for a remand in a case like this one,
    however, because we endorse an alternative basis for affirming the
    trial verdict even assuming (for the sake of argument) error in the
    admission of the eyewitness testimony in this case. We conclude,
    specifically, that any arguable error was harmless beyond a
    reasonable doubt8 in light of other substantial evidence connecting
    Lujan to the crime in question.
    ¶53 We can evaluate the harmlessness of the eyewitness
    identification testimony by considering “the importance of the
    witness’ testimony in the prosecution’s case, whether the testimony
    was cumulative, the presence or absence of evidence collaborating or
    contradicting the testimony of the witness on material points, the
    extent of cross-examination otherwise permitted, and, of course, the
    overall strength of the prosecution’s case.” State v. Villarreal, 
    889 P.2d 419
    , 425–26 (Utah 1995) (citation omitted). And here we harbor no
    reasonable doubt that the jury would still have convicted Lujan even
    without the testimony from the eyewitness.
    ¶54 Even without Lujan’s eyewitness identification, the jury
    would still have had the description of the robber and corroboration
    from the police that Lujan largely matched that description. The jury
    also would have heard that Lujan was found when police followed a
    trail of liquid on the ground from where the stolen car had been
    parked and leading north out of the driveway. Significantly, the jury
    would have heard that the trail of liquid led them to find the stolen
    car parked a few blocks away near an elementary school—and to
    find Lujan “curled into a ball” and hiding next to a fenced-off air
    conditioning unit in the adjacent school yard. Lujan was the only
    person found in the area, and he largely fit the description of the
    robber. And when the police found Lujan he expressed the same
    _____________________________________________________________
    8 This is the federal standard for harmlessness of constitutional
    errors under Chapman v. California, 
    386 U.S. 18
    , 24 (1967). We apply
    this standard here based on the arguendo assumption that there may
    have been a constitutional violation in admitting eyewitness
    identification testimony that could be thought to have run afoul of
    the above-stated due process standard.
    18
    Cite as: 
    2020 UT 5
    Opinion of the Court
    concern the robber had raised earlier that night—stating “somebody
    is following me.”
    ¶55 It is also significant that Lujan challenged only the
    admission of the in-court and show-up identifications given by the
    eyewitness. With this in mind, we may presume for purposes of our
    harmlessness analysis that the jury would have heard a separate
    identification given by the eyewitness—the identification given in
    the lineup. Thus, the jury would also have been told that four
    months after the robbery, two suspects were identified from a
    lineup, and that only one of them was the only person located within
    minutes of the early-morning robbery a short distance from the
    stolen car, and who largely matched the description given to the
    police minutes before.
    ¶56 In light of all the evidence we conclude that any error in
    admitting the eyewitness identification testimony was harmless
    beyond a reasonable doubt. The in-court and showup identifications
    were undoubtedly important to the prosecution’s case. But we think
    that evidence was cumulative and largely unnecessary. And in light
    of the other evidence implicating Lujan we hold that any potential
    error in the district court’s admission of his eyewitness identification
    was harmless beyond a reasonable doubt. We affirm the trial verdict
    against Lujan on this basis.
    III
    ¶57 Eyewitness identification testimony presents difficult
    problems for our courts. Our past decisions could be read to suggest
    that the admissibility of such evidence should be judged in the first
    instance under a due process standard framed by factors identified
    in our opinion in State v. Ramirez, 
    817 P.2d 774
     (Utah 1991). We now
    repudiate that notion. We hold that the admissibility of this kind of
    evidence is to be measured in the first instance by our rules of
    evidence. And we clarify that in cases in which eyewitness testimony
    is procured by unnecessarily suggestive police misconduct, the role
    of the due process inquiry is a limited one—a secondary backstop to
    the threshold question of admissibility under our rules of evidence.
    19
