    No. 15SC770, Vigil v. People—Criminal Law—Jury—Evidence—Witnesses.
    Vigil sought review of the court of appeals’ judgment affirming his
    convictions of second degree burglary and second degree aggravated motor
    vehicle theft. As pertinent to the issues on review in the supreme court, the trial
    court denied Vigil’s for-cause challenge to Juror C.A. but granted the prosecution’s
    challenge to Juror D.K. At trial, and over defense counsel’s objection, an officer
    was permitted to opine without qualification as an expert that Vigil’s shoes
    visually matched shoeprints he photographed at the crime scene. With regard to
    Vigil’s assignments of error concerning these rulings, the court of appeals
    concluded that the trial court had not abused its discretion by denying Vigil’s
    challenge to Juror C.A.; that any error committed in granting the prosecution’s
    challenge to prospective Juror D.K. would in any event have been harmless; and
    that the trial court did not abuse its discretion in allowing the officer to offer a lay
    opinion concerning the shoeprint comparison in question.
    The supreme court affirmed, ruling that the trial court did not abuse its
    discretion in denying Vigil’s challenge to Juror C.A.; granting the prosecution’s
    challenge to prospective Juror D.K., even if it amounted to an abuse of discretion,
    did not result in any violation of Vigil’s rights; and the trial court did not abuse its
    discretion in admitting the officer’s testimony as lay opinion.

    ¶1    Vigil sought review of the court of appeals’ judgment affirming his
    convictions of second degree burglary and second degree aggravated motor
    vehicle theft. As pertinent to the issues on review in the supreme court, the trial
    court denied Vigil’s for-cause challenge to Juror C.A. but granted the prosecution’s
    challenge to Juror D.K. At trial, and over defense counsel’s objection, an officer
    was permitted to opine without qualification as an expert that Vigil’s shoes
    visually matched shoeprints he photographed at the crime scene. With regard to
    Vigil’s assignments of error concerning these rulings, the court of appeals
    concluded that the trial court had not abused its discretion by denying Vigil’s
    challenge to Juror C.A.; that any error committed in granting the prosecution’s
    challenge to prospective Juror D.K. would in any event have been harmless; and
    that the trial court did not abuse its discretion in allowing the officer to offer a lay
    opinion concerning the shoeprint comparison in question.
    ¶2    Because the trial court did not abuse its discretion in denying Vigil’s
    challenge to Juror C.A.; because granting the prosecution’s challenge to
    prospective Juror D.K., even if it amounted to an abuse of discretion, did not result
    in any violation of Vigil’s rights; and because the trial court did not abuse its
    discretion in admitting the officer’s testimony as lay opinion, the judgment of the
    court of appeals is affirmed.
    2
    I.
    ¶3    Nathan Richard Vigil was charged with first degree aggravated motor
    vehicle theft, second degree burglary, theft, and attempt to commit second degree
    burglary in connection with the disappearance of a truck, motorcycle, and various
    other items of personal property from a farm in Conejos County. Although the
    attempted burglary count was dismissed and the defendant was acquitted of theft,
    he was convicted of second degree burglary and a lesser included offense of
    second degree aggravated motor vehicle theft. He was sentenced to concurrent
    terms of six years and eighteen months in the custody of the Department of
    Corrections.
    ¶4    Evidence was presented at trial from which the jury could find that in
    November 2010, the victim discovered that his truck, motorcycle, and other
    personal property were missing from his farm. An officer of the Conejos County
    Sheriff’s Department responded to the farm and photographed shoeprints near
    the area where the truck had been parked. Witnesses informed the officer that the
    defendant had asked them to tow a truck to a trading post in the area but that they
    had not realized at the time that the truck belonged to the victim. While the
    defendant was being held for a different crime at the Alamosa County Sheriff’s
    Office, the officer examined his shoes and determined that they “visually
    matched” shoeprints on the victim’s farm.
    3
    ¶5    During voir dire, Juror C.A. indicated that he knew the victim’s family and
    that he might work on the father’s farm equipment sometime in the future, and he
    appeared equivocal as to whether he could render an impartial verdict for these
    reasons. The court denied defense counsel’s challenge for cause after directly
    asking C.A. if he could evaluate the victim’s testimony “just like all the other
    witnesses who will testify,” and after receiving C.A.’s answer, “I think I could.”
    The court subsequently granted a prosecution challenge to prospective Juror D.K.
    on the ground that he was biased against the police and prosecution. Ultimately,
    both the prosecution and defense exhausted their allotted number of peremptory
    challenges, and neither used a peremptory challenge to strike Juror C.A. nor
    requested any additional challenge.
    ¶6    Without qualification as an expert and over defense objection at trial, the
    investigating officer in question was permitted to opine, on the basis of his
    observation of what he considered to be identical “Skechers” emblems and similar
    size, that the soles of the shoes he examined at the Sheriff’s Office “visually
    matched the prints that were out on the scene.”
    ¶7    On appeal, the intermediate appellate court affirmed the defendant’s
    convictions. With regard to the defendant’s assignments of error concerning these
    three rulings of the trial court, the appellate court found that the ruling concerning
    Juror C.A. fell within the broad discretion permitted trial courts when ruling on
    4
    challenges of juror bias; that any error, had one occurred, in granting the
    prosecution’s challenge to prospective Juror D.K. was necessarily harmless; and
    that the trial court did not abuse its discretion in admitting lay opinion of shoeprint
    comparison.
    ¶8    The defendant petitioned this court for a writ of certiorari.
    II.
    A.
    ¶9    Criminal defendants in this jurisdiction are entitled to trial by an impartial
    jury of the county or district in which the offense was alleged to have been
    committed.    Colo. Const. art. II, § 16.       Within constitutional limitations, the
    legislature determines the qualifications for jury service. People v. White, 
    242 P.3d 1121
    , 1124 (Colo. 2010).
    ¶10   Section 105 of the Uniform Jury Selection and Service Act, §§ 13-71-101 to
    -145, C.R.S. (2019), initially defines qualification for jury service in terms of
    citizenship and either residency or habitation in a particular county, but it then
    provides a number of specific conditions that will nevertheless disqualify an
    otherwise qualified prospective juror. § 13-71-105(1), (2), C.R.S. (2019). Although
    a prospective juror may therefore be qualified in terms of citizenship and vicinage,
    he nevertheless “shall be disqualified” for failing to meet any of a number of other
    5
    conditions related to such things as his age, facility with the English language,
    physical or mental capabilities, familial obligations, and prior jury service. 
    Id. ¶11 The
    absence of any qualification prescribed by statute to render a person
    competent as a juror is itself designated cause for removal, on the basis of which a
    challenge by one of the parties must be sustained. § 16-10-103(1)(a), C.R.S. (2019).
    Beyond the actual absence of some statutory qualification, however, the legislature
    has enumerated a number of other grounds that will also support a challenge for
    cause in criminal cases, broadly involving circumstances implicating a prospective
    juror’s ability to remain impartial. These circumstances include such things as the
    prospective juror’s relationship with the defendant or counsel, any prior adverse
    relationship with the defendant in a civil or criminal matter, prior juror service or
    service as a witness in a related matter, the existence of a fiduciary relationship
    with the defendant or a victim, and employment by either a law enforcement
    agency or the public defender’s office. § 16-10-103(1)(a)–(k). The detection of
    actual enmity or bias toward the defendant or the state is, of course, also expressly
    designated cause for removal. § 16-10-103(1)(j).
    ¶12   In addition to permitting each party to challenge prospective jurors for
    cause, the legislature has provided a specific number of challenges to each side,
    varying with the nature of the charge and circumstances of the particular
    prosecution, to be exercised peremptorily. § 16-10-104(1), C.R.S. (2019). As the
    6
    term implies, these challenges may, within constitutional limitations, be exercised
    without regard for or specification of any reason whatsoever. The statute directs
    that such peremptory challenges are to be exercised “as provided by applicable
    rule of criminal procedure.” § 16-10-104(2). Rule 24(d) of the Colorado Rules of
    Criminal Procedure not only provides the mechanics and timing for exercising
    peremptory challenges but also permits the trial court to add peremptory
    challenges to either side, or to both sides, for good cause shown.
    ¶13   Because challenges for cause, unlike peremptory challenges, are limited
    only by statutory grounds for removal and not in number, a trial court may
    entertain numerous challenges for cause from either or both sides during the
    selection of a single jury. As the Supreme Court has noted, often such challenges
    are “fast paced, made on the spot and under pressure,” and the court “must be
    prepared to decide [them], often between shades of gray, ‘by the minute.’” United
    States v. Martinez-Salazar, 
    528 U.S. 304
    , 316 (2000) (citation omitted). And while
    some of the qualifications for jury service and other statutory grounds justifying a
    challenge for cause are matters of law determinable with relative certainty, others
    are not.
    ¶14   The question whether there exists a state of mind in any particular
    prospective juror evincing enmity or bias toward the defendant or the state such
    that he cannot judge the matter fairly and impartially is necessarily a matter
    7
    involving an exercise of discretion on the part of the trial court and therefore a
    range of permissible judgments about the ability and willingness of that
    prospective juror. See Carrillo v. People, 
    974 P.2d 478
    , 485–86 (Colo. 1999). We have
    previously recognized “the trial court’s unique role and perspective,” and the
    “preferred position” in which it finds itself, in evaluating a prospective juror’s
    credibility, demeanor, and sincerity in explaining his state of mind. 
    Id. at 486
    (quoting in part People v. Macrander, 
    828 P.2d 234
    , 239 (Colo. 1992), overruled in part
    by People v. Novotny, 
    2014 CO 18
    , ¶ 27, 
    320 P.3d 1194
    , 1203). For these reasons,
    among others, such assessments by a trial court are subject to a “very high
    standard of review,” 
    id. at 485–86,
    meriting a finding that the court has abused its
    discretion only if its ultimate ruling is “manifestly arbitrary, unreasonable, or
    unfair.” Freedom Colo. Info., Inc. v. El Paso Cty. Sheriff’s Dep’t, 
    196 P.3d 892
    , 899
    (Colo. 2008). In determining whether a trial court has abused its discretion,
    reviewing courts have therefore been admonished from considering merely
    whether they would have reached the same conclusion and, instead, must affirm
    as long as the trial court’s decision fell within a range of reasonable options.
    Churchill v. Univ. of Colo. at Boulder, 
    2012 CO 54
    , ¶ 74, 
    285 P.3d 986
    , 1008 (quoting
    E–470 Pub. Highway Auth. v. Revenig, 
    140 P.3d 227
    , 230–31 (Colo. App. 2006)).
    ¶15   Even a ruling on a challenge for cause that clearly falls outside this
    acceptable range and is therefore erroneous, however, will not necessarily result
    8
    in a violation of a criminal defendant’s right to an impartial jury. Should a
    prospective juror be erroneously removed for cause, that action, in and of itself,
    will not result in a biased juror sitting in judgment of the defendant. By the same
    token, the defendant’s right to an impartial jury can be adversely affected by an
    erroneous denial of his challenge for cause only if that juror is not otherwise
    removed, as by a different challenge for cause or a challenge exercised
    peremptorily.
    ¶16   In a series of cases decided over the last quarter-century, the United States
    Supreme Court has retreated from its earlier pronouncements concerning the role
    and importance of peremptory challenges in jury selection and has now made
    clear that peremptory challenges have no basis in the federal constitution and are,
    instead, purely a creature of legislation. Rivera v. Illinois, 
    556 U.S. 148
    , 157 (2009)
    (“[T]here is no freestanding constitutional right to peremptory challenges.”).
    Recounting the long history of legislative provision for peremptory challenges in
    federal criminal trials, and construing the current provision approved by Congress
    as Fed. R. Crim. P. 24, the Court has more recently emphasized the fact that a
    principal reason for permitting peremptory challenges has always been to help
    secure the constitutional guarantee of trial by an impartial jury, 
    Martinez-Salazar, 528 U.S. at 314
    –16; that exercising the authorized number of peremptory
    challenges is all that the parties are entitled to by the rule, 
    id. at 315;
    that the
    9
    decision of a defendant to use one of his peremptory challenges to cure what turns
    out to be an erroneous denial of a for-cause challenge therefore does not impair
    his statutory right, 
    id. at 317;
    and that the mistaken denial of a state-provided
    peremptory challenge does not, without more, violate the federal constitution,
    
    Rivera, 556 U.S. at 158
    .
    ¶17   In Novotny, we reconsidered a line of authority in this jurisdiction dictating
    automatic reversal for any erroneous ruling on a challenge for cause adversely
    impacting the defendant’s ability to shape the composition of the jury through the
    use of peremptory challenges. ¶¶ 
    14–17, 320 P.3d at 1199
    –1200. Much as the
    Supreme Court had done in disavowing its earlier pronouncements from Swain v.
    Alabama, 
    380 U.S. 202
    , 219 (1965), and those cases on which it relied, see 
    Rivera, 556 U.S. at 160
    ; 
    Martinez-Salazar, 528 U.S. at 317
    n.4, we overturned this line of our
    own precedents as having been substantially undermined by developments in the
    harmless-error doctrine in general, and the structural error/trial error dichotomy
    in particular, Novotny, ¶ 
    17, 320 P.3d at 1200
    . Because we were there faced with
    the specific question whether automatic reversal was the proper remedy for such
    an error in light of the subsequently developed structural error doctrine, we
    reserved the question whether the use of a peremptory challenge to remove a
    prospective juror for whom a challenge for cause was erroneously denied must be
    disregarded as harmless in every case. 
    Id. at ¶¶
    1–2, 320 P.3d at 1196
    . Instead we
    10
    remanded to the court of appeals for consideration of the appropriate remedy in
    that particular case. 
    Id. at ¶
    27, 320 P.3d at 1203
    . In the intervening five years, a
    number of divisions of the intermediate appellate court have reasoned that in the
    absence of bad faith or actual participation by a biased juror, the use of a
    peremptory challenge to cure an erroneous ruling on a defendant’s challenge for
    cause is necessarily harmless. People v. Marciano, 
    2014 COA 92M
    -2, ¶ 10, 
    411 P.3d 831
    , 835 (citing People v. Wise, 
    2014 COA 83
    , ¶¶ 28–29, 
    348 P.3d 482
    , 489); People v.
    Wilson, 
    2014 COA 114
    , ¶ 23, 
    356 P.3d 956
    , 963 (quoting Wise, ¶

    );
    Wise, ¶¶ 28–29, 28 
    n.6, 348 P.3d at 489
    & n.6.
    ¶18   Although in Novotny we focused on the propriety of automatic reversal for
    what we had previously considered to be the “forced” use of a defendant’s
    peremptory challenge to cure an erroneous ruling on a challenge for cause, our
    reliance not only on developments in the harmless error doctrine, but also on more
    recent Supreme Court jurisprudence finding a lack of any constitutional
    underpinning whatsoever for peremptory challenges, largely foreshadowed
    today’s holding. Today we expressly answer the question left open in Novotny by
    disavowing our prior understanding that the constitution, statute, rule, or some
    combination of the three, grants a criminal defendant a right to shape the jury
    through the use of peremptory challenges.
    11
    ¶19   In both the context of erroneously denying a defense challenge for cause and
    the context of erroneously granting a prosecution challenge for cause, we had
    come to believe that a criminal defendant, quite apart from being denied his
    constitutional right to an impartial jury, is harmed, or disadvantaged tactically, see
    Blades v. DaFoe, 
    704 P.2d 317
    , 322 (Colo. 1985), overruled in part by Laura A. Newman,
    LLC v. Roberts, 
    2016 CO 9
    , ¶ 2, 
    365 P.3d 972
    , 973, by being deprived of an equal
    opportunity to change the composition of, or “shape,” the jury, see People v. Lefebre,
    
    5 P.3d 295
    , 304 (Colo. 2000), overruled in part by Novotny, ¶ 
    27, 320 P.3d at 1203
    ;
    
    Macrander, 828 P.2d at 244
    . For this proposition, we relied in part on pre-harmless
    error caselaw finding that violation of the peremptory challenge statute alone
    amounted to harm requiring reversal, see, e.g., 
    Macrander, 828 P.2d at 243
    (relying
    on Denver City Tramway Co. v. Kennedy, 
    117 P. 167
    (Colo. 1911)), and in part on
    now-rejected Supreme Court caselaw implicitly finding federal constitutional
    underpinnings of peremptory challenges, see, e.g., 
    Lefebre, 5 P.3d at 306
    (understanding Ross v. Oklahoma, 
    487 U.S. 81
    (1988), to hold that a federal due
    process violation results if a trial court fails to provide a defendant his state law-
    granted right to peremptory challenges, a proposition expressly rejected by the
    Court in 
    Rivera, 556 U.S. at 158
    ).      In our most recent consideration of this
    proposition, and the only instance in which we actually relied on language from
    the statute and rule themselves, we announced that “[t]he function of peremptory
    12
    challenges in a criminal proceeding is to allow both the prosecution and the
    defense to secure a more fair and impartial jury by enabling them to remove jurors
    whom they perceive as biased, even if the jurors are not subject to a challenge for
    cause,” 
    Lefebre, 5 P.3d at 303
    , and we inferred that the allowance by statute and
    rule of the same number of peremptory challenges, in the absence of good cause
    to add peremptory challenges to one or both sides, was intended to further this
    end, 
    id. at 303–04.
    ¶20   While providing the same number of peremptory challenges to both the
    defense and prosecution in the absence of good reason to do otherwise clearly
    evidences an intent to permit, at least initially, each side to exercise the same
    number of peremptory strikes, on its face it implies virtually nothing about the
    purpose for providing for peremptory, in addition to for-cause, challenges. Much
    like the federal legislative authorization for peremptory strikes, our statute simply
    provides a specified number of strikes, varying with the nature of the charges and
    number of defendants, and our rule merely embellishes on that provision by
    permitting additional strikes to the prosecution or defense for good cause. Our
    prior cases fail to suggest support in the text or legislative history of either
    provision for any underlying legislative intent to permit the parties to shape the
    jury to their tactical advantage, as distinguished from merely to aid in the ultimate
    acquisition of a constitutionally required fair and impartial jury.
    13
    ¶21   In Martinez-Salazar, the Supreme Court expressly rejected the notion that a
    criminal defendant who expends one of his peremptory challenges to cure an
    erroneous ruling on his challenge for cause has effectively been “forced” to do so
    in order to remove the objectionable veniremember and, therefore, has effectively
    been deprived of one of the strikes allotted him by Rule 
    24. 528 U.S. at 314
    –15.
    The Court reasoned that where the defendant has exercised the number of
    peremptory challenges permitted by the rule, whatever the reason for his decision
    to do so, he has received nothing less than that to which the rule entitled him. 
    Id. at 315.
    Following this same logic, where the court erroneously grants a challenge
    for cause, the party making that challenge has not effectively received a
    peremptory challenge beyond the number allotted him by statute, and therefore
    unless the court acted in bad faith to assist him in some way other than acquiring
    a fair and impartial jury, he has received no more than that to which the statute
    entitled him.
    ¶22   We are not unmindful that retreating from the shape-the-jury rationale that
    led to the now-overturned remedy of automatic reversal further implicates the
    doctrine of stare decisis. For virtually the same reasons we found it important and
    justified in Novotny to partially overturn this line of our own prior holdings, we
    consider it similarly justified to now overturn them in full. To the extent that our
    prior rationale was based on pre-harmless error holdings, the constitutional
    14
    significance of peremptory challenges, and even federal due process implications
    of violating state peremptory challenge law, those premises have now all been
    independently swept away by developments in the jurisprudence of the Supreme
    Court which we have either already adopted or by which we are constitutionally
    bound. As we indicated in Novotny, the venerable principle of stare decisis is not
    an immutable law but rather ultimately a matter of discretion for a high court, and
    when, as here, the bases for a prior holding, whether legal or factual, no longer
    support that holding, and especially where retreating from that holding would not
    unfairly upset settled expectations, overturning it is not only merited but is in fact
    an obligation of the high court. Novotny, ¶¶ 
    24–26, 320 P.3d at 1202
    –03.
    B.
    ¶23   Vigil contends that the trial court erred by denying his challenge for cause
    to Juror C.A. Though Juror C.A. initially appeared equivocal as to his ability to
    remain impartial due to his acquaintance with the victim’s family and the
    possibility that he might work on the father’s farm equipment sometime in the
    future, the trial judge sought, and C.A. expressly gave, his assurance that he
    thought he could evaluate the victim’s testimony “just like all the other witnesses
    who will testify.” It was for the trial court not only to assess the juror’s credibility
    but also to evaluate whether he would be able to render an impartial verdict.
    15
    ¶24   Contrary to the assertion of the defendant, it was unnecessary for the trial
    court to query the prospective juror in precise terms of bias and impartiality and
    to receive his express assurance that he was not biased and both could and would
    render an impartial verdict. While the ultimate aim of jury selection is to produce
    an unbiased and impartial jury, Smith v. Dist. Court, 
    907 P.2d 611
    , 613 (Colo. 1995),
    neither the United States Constitution nor the Colorado Constitution “dictate[s] a
    catechism for voir dire.” People v. Harlan, 
    8 P.3d 448
    , 464 (Colo. 2000) (alterations
    in original) (quoting Morgan v. Illinois, 
    504 U.S. 719
    , 729 (1992)), overruled in part by
    People v. Miller, 
    113 P.3d 743
    , 748 (Colo. 2005). Similarly, the statutory requirement
    that a challenge for cause be sustained as to any juror having a state of mind
    evincing enmity or bias toward the defendant or the state also makes clear that no
    person shall be disqualified by reason of having formed an opinion as to guilt or
    innocence if the court is satisfied from examination of the juror or from other
    evidence that he will render a verdict according to the law and the evidence
    submitted to the jury at the trial. § 16-10-103(1)(j). Where the source of concern
    for C.A.’s impartiality arose from his prior relationship with the victim’s family, it
    was within the trial court’s unique role in jury selection and discretion to conclude
    from C.A.’s clarification that he could assess the victim’s testimony just as any
    other witness and that he could render an impartial verdict.
    16
    ¶25   With regard to the trial court’s ruling granting the prosecution’s for-cause
    challenge of prospective Juror D.K., whether that ruling amounted to an abuse of
    discretion or not, in the absence of bad faith, which has not been asserted here, see
    Johnson v. Schonlaw, 
    2018 CO 73
    , ¶ 16, 
    426 P.3d 345
    , 350, it could not require
    reversal. Because D.K. did not sit in judgment of the case, that ruling could not
    have deprived the defendant of his constitutional right to a fair and impartial jury;
    and because neither the prosecution nor the defendant is granted any right in this
    jurisdiction, by constitution, statute, or rule, to shape the composition of the jury
    through the use of peremptory challenges, the defendant could not have been
    harmed by the deprivation of any such right.
    III.
    ¶26   In Venalonzo v. People, 
    2017 CO 9
    , ¶ 22, 
    388 P.3d 868
    , 875, this court recently
    clarified the distinction between expert and lay opinion within the contemplation
    of Rules 701 and 702 of the Colorado Rules of Evidence. If opinion testimony could
    be based on an ordinary person’s experiences or knowledge, the testimony in
    question may be admitted as a lay opinion. 
    Id. at ¶
    2, 388 P.3d at 871
    . If, however,
    a witness offers testimony in the nature of an opinion that could not be formed
    without reliance on specialized experiences, knowledge, or training, for that
    testimony to be admissible, the witness must be qualified as an expert. 
    Id. 17 ¶27
      Vigil asserts that the officer’s opinion testimony constituted improper
    expert testimony in the guise of lay testimony. At trial, the prosecution asked the
    officer to compare the shoeprints he photographed at the victim’s farm with the
    photos he took of Vigil’s shoes. The officer merely opined that the print of Vigil’s
    shoes “visually matched the prints that were out on the scene.” He later explained
    that he based his comparison of the shoeprint and the shoe itself on their identical
    “Skechers” emblems and similar size measurements.
    ¶28   Because neither a comparison of a shoe and an imprint left in the dirt by a
    shoe based on the size of each, nor a visual comparison of an emblem on the sole
    of a shoe and an imprint in the dirt left by a shoe, is beyond the ken of an ordinary
    person without specialized training or experience of any kind, 
    id., an opinion
    that
    the defendant’s shoe caused the imprint in the dirt observed by the officer was
    admissible as a lay opinion. Although the officer in question made reference to
    his experience and training with regard to evidence collection generally, that
    testimony could not reasonably have been understood to suggest that the officer
    had specialized training in the comparison of shoeprints or that his opinion was
    entitled to any greater weight than the opinion of anyone capable of measuring
    the size of the two and visually observing the emblem and imprint in the dirt. The
    trial court therefore did not abuse its discretion by admitting the officer’s shoeprint
    comparison testimony as lay testimony pursuant to CRE 701.
    18
    ¶29   We also reject the defendant’s contention that the officer’s testimony was
    unhelpful to the jury. Although he photographed the prints in question, his
    measurements of the shoes themselves and the imprints at the scene were the first-
    hand observations of the evidence in question.
    IV.
    ¶30   Because the trial court did not abuse its discretion in denying Vigil’s
    challenge to Juror C.A. for cause; because any error the trial court committed in
    granting the prosecution’s challenge to prospective Juror D.K. for cause did not
    result in a violation of Vigil’s constitutional, statutory, or rule-based rights, and
    therefore does not require reversal; and because the trial court properly admitted
    the officer’s testimony as lay opinion, the judgment of the court of appeals is
    affirmed.
    JUSTICE HOOD specially concurs, and JUSTICE HART joins in the special
    concurrence.
    JUSTICE GABRIEL dissents.
    19
    JUSTICE HOOD, specially concurring.
    ¶31   For the reasons set forth below, I join the court’s judgment in all respects. I
    write separately, however, to explain why I believe People v. Novotny, 
    2014 CO 18
    ,
    
    320 P.3d 1194
    , dictates today’s result as to prospective Juror D.K. and why I believe
    the division majority’s “clear bias” rationale as to Juror C.A. was incorrect.
    Therefore, I respectfully concur.
    I. Prospective Juror D.K. and Prejudice Post-Novotny
    ¶32   The majority acknowledges that the court’s decision in Novotny “largely
    foreshadowed today’s holding.” Maj. op. ¶ 18. The majority then explains that
    “[t]oday we expressly answer the question left open in Novotny by disavowing our
    prior understanding that the constitution, statute, rule, or some combination of the
    three, grants a criminal defendant a right to shape the jury through the use of
    peremptory challenges.” Id.; see also 
    id. at ¶
    20 (“Our prior cases fail to suggest
    support in the text or legislative history of either provision for any underlying
    legislative intent to permit the parties to shape the jury to their tactical advantage,
    as distinguished from merely to aid in the ultimate acquisition of a constitutionally
    required fair and impartial jury.”).
    ¶33   The majority’s characterization of Novotny as simply foreshadowing today’s
    holding is puzzling, however, given Novotny’s rationale. Of course, the opinion is
    best known for overruling the automatic-reversal rule of People v. Macrander,
    1
    
    828 P.2d 234
    (Colo. 1992).     But in overruling Macrander, the court expressly
    disavowed the notion that parties have a due process right to use peremptory
    challenges to “shape” the jury. See, e.g., Novotny, ¶ 
    22, 320 P.3d at 1201
    (“Whether
    or not the Fourteenth Amendment due process violation we mistakenly identified
    in Lefebre could have itself catapulted impairment of a defendant’s ability to shape
    the jury into this limited class of fundamental constitutional errors, the Supreme
    Court has since made abundantly clear that no such due process protection exists
    for state-granted peremptory challenges.”).
    ¶34   Thus, from my perspective, Novotny did more than foreshadow today’s
    holding. It foreordained it. Were this simply a case of foreshadowing—with a
    genuine choice remaining—I might choose a different path. But, as it is, I feel
    compelled to join the decision because we have done no more than arrive at the
    end of the path on which Novotny placed us. Although I dissented in Novotny,
    stare decisis compels my reluctant obedience to its dictates today. On that basis, I
    concur as to the Juror D.K. portion of the court’s holding in the case at bar.
    II. Juror C.A. and the Standard for Reviewing Bias
    ¶35   As to Juror C.A., I note that the majority correctly eschewed the division’s
    articulation of a “clear bias” standard of review in evaluating whether Juror C.A.
    should have been dismissed for cause. I write separately to spell out why I think
    this was a wise choice.
    2
    ¶36   The division concluded that “a trial court is not compelled to grant a
    challenge for cause where a juror’s responses are equivocal and do not articulate
    a clear expression of bias . . . .” People v. Vigil, 
    2015 COA 88M
    , ¶ 11, __ P.3d __; see
    also 
    id. at ¶
    15 (“We do not agree, however, that the juror’s answers taken as a
    whole revealed any ‘clear bias’ that ‘would make his dismissal from the jury
    compulsory.’” (quoting People v. Young, 
    16 P.3d 821
    , 826 (Colo. 2001))). Because
    Juror C.A. “did not clearly evince bias,” the division held that “Juror C.A.’s
    equivocal responses did not require the trial court to excuse him.” 
    Id. at ¶¶
    11, 14.
    ¶37   In gleaning this “clear bias” standard, the division relied on references to
    clear bias in several of our decisions, the most relevant being Carrillo v. People,
    
    974 P.2d 478
    , 488 (Colo. 1999), and 
    Young, 16 P.3d at 826
    . But I believe the
    division’s reliance is misplaced.
    ¶38   True, in concluding in Carrillo that the trial court did not abuse its discretion
    in denying a defendant’s challenge for cause, this court observed that a
    prospective juror’s “answers to questions about his working relationship with [the
    victim’s father] appear ambiguous and fail to articulate a clear expression of bias
    requiring his 
    dismissal.” 974 P.2d at 488
    . And, following a similar conclusion in
    Young, we briefly noted in dicta that the record did “not reveal that [the challenged
    juror] had any clear bias against [the defendant] which would make his dismissal
    from the jury 
    compulsory.” 16 P.3d at 826
    .
    3
    ¶39   But while these observations may permit an appellate court to consider
    whether a juror’s responses articulated a “clear expression of bias” when
    reviewing the challenged voir dire as a whole, they do not announce a new legal
    standard for determining whether a juror evinced enmity or bias, as the division
    did here. Not only is such a standard absent from the challenge-for-cause statute’s
    plain language, see § 16-10-103(1)(j), C.R.S. (2019), it also doesn’t make sense. After
    all, if a trial court can never abuse its discretion in denying a challenge for cause if
    a prospective juror’s responses are equivocal, appellate review of such decisions
    could become a hollow exercise. Rare is the case in which a prospective juror
    unyieldingly clings to a clear statement of bias. Unless the prospective juror is
    intent on being excused, probing by counsel and the court typically leaves us with
    a muddle of equivocal statements, not unlike what we see here as to Juror C.A. In
    the absence of some evidence of rehabilitation demonstrating that the juror is
    willing to render a verdict according to the law and evidence—and not based on
    enmity or bias—equivocation alone can make it manifestly unreasonable or unfair
    to deny a challenge for cause.       Accordingly, the majority properly avoided
    applying a “clear bias” standard of review.
    ¶40   Likewise, the majority is right to tacitly reject the defendant’s argument for
    a “genuine doubt” standard. Pointing to our decision in People v. Russo, 
    713 P.2d 356
    , 362 (Colo. 1986), in which we stated in part that “[i]f the trial court has genuine
    4
    doubt about the juror’s ability to be impartial . . . , it should resolve the doubt by
    sustaining the challenge,” Vigil argues that an expression of doubt as to
    impartiality, minus rehabilitation expressly regarding impartiality, requires the
    prospective juror’s dismissal for cause. But this “genuine doubt” language is also
    nowhere to be found in the challenge-for-cause statute. See § 16-10-103(1)(j).
    ¶41   Instead, the majority correctly focuses on the statute’s plain language. Maj.
    op. ¶ 11 (“The detection of actual enmity or bias toward the defendant or the state
    is, of course, also expressly designated cause for removal.”); see also 
    id. at ¶
    24
    (“Similarly, the statutory requirement that a challenge for cause be sustained as to
    any juror having a state of mind evincing enmity or bias toward the defendant or
    the state also makes clear that no person shall be disqualified by reason of having
    formed an opinion as to guilt or innocence if the court is satisfied from examination
    of the juror or from other evidence that he will render a verdict according to the
    law and the evidence submitted to the jury at the trial.”).
    ¶42   And here, there was at least some follow-up by the trial court. I therefore
    agree with the majority that under the highly deferential standard of review,
    premised on the trial court’s opportunity to see and interact with the juror, there
    was no abuse of discretion.
    ¶43   In the end, the division put it well:
    Juror C.A.’s statement that he would treat [the victim’s] testimony the
    same as other witnesses’ testimony meant that he would treat [the
    5
    victim’s] testimony impartially (i.e., he would not be unduly partial
    toward [the victim] when assessing his testimony). Juror C.A.’s
    statement that he would treat [the victim’s] testimony impartially was
    some evidence that he would render an impartial verdict (i.e., he
    would not be unduly partial toward [the victim] when rendering the
    verdict).
    With the benefit of hindsight and time to parse the record, we could
    conceive of more complete follow-up questions for Juror C.A.
    However, simply because we could construct additional useful
    questions for the juror does not necessarily give us license to overturn
    the trial court’s decision. The restraint on our review of the trial
    court’s ruling reflects the supreme court’s considered judgment of the
    respective roles of the trial and appellate courts regarding challenges
    for cause. Thus, we must resist the temptation to second-guess the
    trial court’s decision based on a cold record.
    Although the trial court’s questioning could have been more
    comprehensive, it still elicited a response significant to the challenge
    for cause, as explained above. Therefore, even if imperfect, the trial
    court’s questioning of the juror weighs in favor of affirmance.
    Vigil, ¶¶ 16–18 (internal citations omitted).
    ¶44   In concluding, I echo the sentiment expressed by the division majority. The
    trial court’s follow-up questioning of Juror C.A. regarding his potential bias in
    favor of the victim in this case was less than ideal. But this was a quintessential
    game-time call. The trial judge was there; we weren’t. Moreover, I take comfort
    in the fact that this court tends to see outliers. I place my faith in Colorado’s trial
    judges to go beyond perfunctory questioning that superficially protects the record
    but endangers a defendant’s (and, when at issue, the state’s) right to a truly fair
    and impartial jury.
    6
    I am authorized to state that JUSTICE HART joins in this special
    concurrence.
    7
    JUSTICE GABRIEL, dissenting.
    ¶45   I agree with the majority’s conclusion that the trial court did not abuse its
    discretion in admitting a police officer’s lay opinion that Vigil’s shoes matched
    shoeprints that the officer had photographed at the crime scene.          Maj. op.
    ¶¶ 28–30. I disagree, however, with the majority’s conclusions that (1) the trial
    court did not abuse its discretion in denying Vigil’s challenge for cause to Juror
    C.A. and (2) any error that the trial court committed in granting the prosecution’s
    challenge for cause as to Juror D.K. did not prejudice Vigil. 
    Id. In particular,
    I
    disagree with the majority’s apparent test for prejudice, which makes it virtually
    impossible for a criminal defendant ever to prove prejudice in this context and
    which I believe results in an unlevel playing field.
    ¶46   Accordingly, I respectfully dissent.
    I. Factual Background
    ¶47   The majority does not quote much of the voir dire examinations of either
    Juror C.A. or Juror D.K. Because those examinations are central to my analysis, I
    discuss them at greater length.
    ¶48   During voir dire, Juror C.A. volunteered that he had “done quite a bit of
    work” for the victim and his family and that he had “gotten along great with them
    for years and years.” The following exchange then occurred with defense counsel:
    1
    [Defense Counsel]: . . . Due to these business relationships you’ve had
    with the alleged victim in this case, do you feel it would be difficult
    for you to render an impartial verdict?
    [Juror C.A.]: I can’t say that. I really can’t. I’d like to say no. I’d like
    to say no, but I don’t know.
    [Defense Counsel]: So what are you saying? Are you saying, yes, you
    can render an impartial [verdict] or no you can’t?
    [Juror C.A.]: It’s something that sits there. I know the people. I really
    do. I don’t know the defendant here.
    [Defense Counsel]: Do you think you may be doing business with
    them in the future?
    [Juror C.A.]: Possibly with the dad. I work out in that area, out in
    Questa. And I come through there, and I do stop and visit with [the
    victim’s father] every once in a while. If he’s got something that’s out
    of whack on his pivots, I go and take care of it for him. I don’t know.
    [Defense Counsel]: Your Honor, I’m going to ask the same thing of
    [Juror C.A.]. He stated he has a business relationship with the—[the
    victim] and his family and may be having business in the future; and
    in the back of his mind, that may make him where he’s not completely
    unbiased or prejudiced in making an ultimate determination.
    THE COURT: Sir, can you evaluate his testimony just the same as the
    testimony of all the other witnesses?
    [Juror C.A.]: His you’re talking about?
    THE COURT: [The victim’s]. Can you evaluate his testimony just like
    all the other witnesses who will testify in this case?
    [Juror C.A.]: I think I could.
    THE COURT: Challenge for cause is denied.
    ¶49   Ultimately, Juror C.A. served as the jury’s foreperson.
    2
    ¶50   Also during voir dire, Juror D.K. noted that he was watching a law
    enforcement officer friend’s farm for him. The prosecution then asked Juror D.K.
    how on a scale of one to ten, with ten being the best, he would “rate” law
    enforcement in Conejos County. D.K. responded, “I would have to split the
    difference and say five because I take it on a case-by-case basis. So some they get
    right; some they get wrong.” He explained this answer by noting that he had
    heard allegations of “heavy-handedness and favoritism, racism,” and when the
    prosecution asked if that would influence how he would look at this case, he
    responded, “It depends on the evidence presented.”
    ¶51   Juror D.K. then observed, “My tendency is for my heart to be in favor of the
    defendant,” and he said that he would “like to let [the defendant] off.” He added,
    however, by way of explanation, “I would like to think the best of most people,”
    including the police in Conejos County, many of whom he thought were “really
    nice guys.” When the prosecution then asked whether his foregoing comments
    meant that he was predisposed to acquit Vigil, he answered, “I’m predisposed to
    let him or his mouthpiece have their say.” Having already exhausted its allotted
    peremptory challenges, the prosecution challenged Juror D.K. for cause.
    ¶52   The court then allowed defense counsel to question Juror D.K., and counsel
    asked him if he could reach a verdict based solely on the evidence presented and
    the court’s instructions. Juror D.K. responded, “Yes, I believe so. I take this
    3
    seriously.” Although he then offered that he had had a negative experience with
    the justice system elsewhere in the past, when defense counsel asked whether that
    experience would affect how he thought today, he replied:
    No. I wouldn’t think so. Again, I take this seriously. It’s a
    responsibility. If a person has done something which society believes
    merits retribution, then that person should be punished; but I don’t
    want to just throw somebody to the dogs unless I’m sure that that
    person deserves the punishment.
    ¶53   Defense counsel followed up by asking if Juror D.K. meant that it would be
    unfair not to afford Vigil the presumption of innocence. D.K. responded, “This is
    the United States. You are presumed innocent until you’re found guilty.” He
    added, however, that although he is a forgiving person, some things should not
    be forgiven, including “murder, rape, incest, thievery, assault, et cetera, et cetera.”
    ¶54   Based on this colloquy, defense counsel passed Juror D.K. for cause. The
    court, however, granted the prosecution’s challenge.
    II. Analysis
    ¶55   I begin by setting forth the law applicable to challenges for cause. I then
    address the trial court’s rulings on the challenges for cause to Jurors C.A. and D.K.,
    and I conclude that the court abused its discretion in denying Vigil’s challenge to
    Juror C.A. and in granting the prosecution’s challenge to Juror D.K. I end by
    addressing the issue of prejudice, and I conclude that (1) because Juror C.A. sat on
    the jury, reversal is required and (2) the majority’s test for prejudice renders it all
    4
    but impossible for a defendant to prove prejudice in this context and results in
    what I believe to be an unlevel playing field.
    A. Law Regarding Challenges for Cause
    ¶56   A fair trial is a basic requirement of due process, and the right to challenge
    a juror for cause is an integral part of a fair trial. People v. Macrander, 
    828 P.2d 234
    ,
    238 (Colo. 1992), overruled on other grounds by People v. Novotny, 
    2014 CO 18
    , ¶ 27,
    
    320 P.3d 1194
    , 1203. To ensure a defendant’s right to a fair trial with an impartial
    jury, a trial court must excuse biased or prejudiced persons from the jury.
    Morrison v. People, 
    19 P.3d 668
    , 672 (Colo. 2000). This requirement is codified in
    section 16-10-103(1)(j), C.R.S. (2019), which requires a court to sustain a challenge
    for cause when “[t]he existence of a state of mind in the juror evinc[es] enmity or
    bias toward the defendant or the state.” Accord Crim. P. 24(b)(1)(X).
    ¶57   Specifically, a trial court must grant a challenge for cause if, among other
    things, a prospective juror is unwilling or unable to accept the basic principles of
    criminal law and render a fair and impartial verdict based on the evidence
    admitted at trial and the court’s instructions. 
    Morrison, 19 P.3d at 672
    . Similarly,
    if the trial court has genuine doubt about the prospective juror’s ability to be
    impartial, it should ordinarily resolve the doubt by sustaining the challenge.
    People v. Russo, 
    713 P.2d 356
    , 362 (Colo. 1986).
    ¶58   Conversely,
    5
    no person summoned as a juror shall be disqualified by reason of a
    previously formed or expressed opinion with reference to the guilt or
    innocence of the accused, if the court is satisfied, from the
    examination of the juror or from other evidence, that he will render
    an impartial verdict according to the law and the evidence submitted
    to the jury at the trial.
    § 16-10-103(1)(j); accord Crim. P. 24(b)(1)(X).
    ¶59   When reviewing a trial court’s denial of a challenge for cause, we review the
    entire voir dire at issue to place the prospective juror’s statements in context, and
    we review the trial court’s ruling on a challenge for cause for an abuse of
    discretion. People v. Young, 
    16 P.3d 821
    , 824 (Colo. 2001). The abuse of discretion
    standard gives deference to the trial court’s credibility assessment of a prospective
    juror’s responses, recognizes the trial court’s unique role and perspective in
    evaluating the demeanor and body language of live witnesses, and serves to
    discourage an appellate court from “second-guessing those judgments based on a
    cold record.” Carrillo v. People, 
    974 P.2d 478
    , 486 (Colo. 1999). Despite the wide
    discretion afforded trial courts, however, appellate courts must not “abdicate their
    responsibility to ensure that the requirements of fairness are fulfilled.” Morgan v.
    People, 
    624 P.2d 1331
    , 1332 (Colo. 1981).
    ¶60   Applying these principles, appellate courts in this state have concluded that
    reversible error occurs when a trial court denies a challenge for cause to a
    prospective juror who expresses doubt as to his or her ability to be impartial and
    6
    neither the prosecution nor the trial court then rehabilitates that juror. See, e.g.,
    People v. Luman, 
    994 P.2d 432
    , 436 (Colo. App. 1999); see also People v. Gurule,
    
    628 P.2d 99
    , 103 (Colo. 1981) (concluding that reversal was required when a
    prospective juror had formed a firm opinion as to the defendant’s guilt and her
    voir dire responses did not sufficiently call that opinion into question so as to raise
    a credibility issue for the court’s determination in ruling on the defendant’s
    challenge for cause); 
    Morgan, 624 P.2d at 1332
    (concluding that the trial court had
    abused its discretion in failing to excuse a prospective juror for cause when the
    juror repeatedly indicated that he would have difficulty applying the principle
    that the burden of proof rested on the prosecution, notwithstanding the fact that
    the juror at one point also said that he could “go along” with the presumption of
    innocence and the defendant’s right to remain silent).
    B. Juror C.A.
    ¶61   In light of the foregoing principles, I would conclude that the trial court
    abused its discretion in denying Vigil’s challenge for cause as to Juror C.A.
    ¶62   As noted above, Juror C.A. consistently expressed doubt as to his ability to
    render an impartial verdict, given his long (“years and years”) and “great”
    relationship with the victim’s family. Specifically, when asked directly whether it
    would be difficult for him to render an impartial verdict, he responded, “I’d like
    to say no, but I don’t know.” He added, “It’s something that sits there. I know the
    7
    people. I really do. I don’t know the defendant here.” And he indicated that he
    anticipated possibly doing business with the victim’s family in the future.
    ¶63   Neither the trial court nor the prosecution asked Juror C.A. directly
    whether, despite his relationship with the victim’s family, he could render an
    impartial verdict and follow the court’s instructions. The court merely asked,
    generally and without reference to Juror C.A.’s expression of doubt as to whether
    he could be fair, whether Juror C.A. could evaluate the victim’s testimony just like
    all of the other witnesses. Although Juror C.A. responded, “I think I could,” this
    response did not resolve his consistent expressions of doubt as to whether he could
    render an impartial verdict, and he never expressed a belief that he could—or that
    he would try to—do so. To the contrary, his statement that he did not know
    whether he could render an impartial verdict stood unrebutted, even after he
    responded to the court’s single question to him.
    ¶64   In these circumstances, I would conclude that the trial court abused its
    discretion in denying Vigil’s challenge for cause as to Juror C.A. See 
    Gurule, 628 P.2d at 103
    ; 
    Morgan, 624 P.2d at 1332
    ; 
    Luman, 994 P.2d at 436
    . Although I
    recognize and respect trial courts’ broad discretion regarding challenges for cause,
    I am also mindful of our obligation as appellate judges not to abdicate our
    responsibility to ensure that the requirements of fairness are fulfilled. 
    Morgan, 624 P.2d at 1332
    . I believe that this case requires our intervention.

    C. Juror D.K.
    ¶65   Applying the above-described legal principles, I would further conclude
    that the trial court abused its discretion in granting the prosecution’s challenge for
    cause as to Juror D.K.
    ¶66   In contrast to Juror C.A., Juror D.K. repeatedly and consistently provided
    assurances that he took his obligations as a juror seriously, that he could reach a
    verdict solely based on the evidence and the court’s instructions, and that he
    understood the presumption of innocence. He even stated that he believed that
    crimes like “thievery,” which was the type of charge that Vigil was facing, should
    not be forgiven.
    ¶67   Nor do I perceive anything in Juror D.K.’s responses indicating a bias
    against either the prosecution or law enforcement. Juror D.K. did no more than
    recognize that police officers, like all other witnesses, are sometimes right and
    sometimes wrong, and he committed to assess their credibility based on the
    evidence. I perceive little difference between these statements and Juror C.A.’s
    statement that he thought he could evaluate the victim’s testimony like that of all
    of the other witnesses, which statement precipitated the trial court’s decision to
    deny Vigil’s challenge for cause as to Juror C.A.
    ¶68   On these facts, although the prosecution may well have wished to exercise
    a peremptory challenge had it had any remaining, I perceive no legitimate basis
    9
    for a challenge for cause as to Juror D.K. Accordingly, I would conclude that the
    trial court abused its discretion in granting that challenge.
    D. Prejudice
    ¶69   Having thus concluded that the trial court abused its discretion in denying
    Vigil’s challenge for cause as to Juror C.A. and in granting the prosecution’s
    challenge for cause as to Juror D.K., the question remains whether either of these
    errors prejudiced Vigil so as to require a new trial.
    ¶70   As to Juror C.A., the majority does not address the question of prejudice
    because it perceived no abuse of discretion in the denial of the challenge for cause.
    For the reasons set forth above, I believe that the trial court did abuse its discretion,
    and the prejudice here is manifest. Not only did a biased juror (i.e., Juror C.A.) sit,
    despite Vigil’s well-founded effort to strike him for cause, but also he served as
    the jury foreperson. Accordingly, I believe that Vigil is entitled to a new trial.
    ¶71   Although the foregoing is sufficient to end my analysis, I feel compelled to
    address the majority’s recitation of the test for prejudice regarding the erroneous
    grant of the prosecution’s challenge for cause as to Juror D.K.
    ¶72   With respect to Juror D.K., the majority concludes that whether the trial
    court’s ruling amounted to an abuse of discretion or not, Vigil suffered no
    prejudice because (1) Juror D.K. did not sit in judgment of the case and therefore
    the court’s ruling could not have deprived Vigil of a fair and impartial jury and
    10
    (2) neither the prosecution nor Vigil had any right to shape the composition of the
    jury through the use of peremptory challenges and therefore Vigil could not have
    been harmed by the deprivation of any such right. Maj. op. ¶ 25. I respectfully
    disagree with this articulation of a test for prejudice because in my view it (1) is
    inconsistent with the framework set forth in Hagos v. People, 
    2012 CO 63
    , ¶¶ 8–14,
    
    288 P.3d 116
    , 118–20, for assessing whether an error in criminal proceedings
    requires reversal; (2) essentially eliminates any inquiry into prejudice in this
    context; and (3) results in an unlevel playing field.
    ¶73   After the court’s decision today, when a defendant’s challenge for cause is
    improperly denied, he or she must exercise a peremptory challenge to excuse the
    biased juror (or risk an appellate court’s finding that he or she waived or invited
    error in allowing the biased juror to sit), and once this is done, the defendant
    apparently can establish prejudice only by showing that a second, independent
    error, namely, the seating of a different biased juror, also occurred. I perceive no
    basis for conflating the prejudice resulting from one error with the merits of a
    second, independent error. Indeed, as Vigil points out, if that were the test, then
    the initial error would become a moot point because a new trial would be required
    based on the second, independent error. I am aware of no other area of law in
    which prejudice is assessed in this manner.
    11
    ¶74   Moreover, such an analysis seems contrary to the framework set forth in
    Hagos, ¶¶ 
    8–14, 288 P.3d at 118
    –20, for determining whether an error in criminal
    proceedings requires reversal. As pertinent here, in Hagos, we observed that we
    review preserved trial errors of constitutional dimension for constitutional
    harmless error, which requires reversal if there is a reasonable possibility that the
    error might have contributed to the conviction. 
    Id. at ¶
    11, 288 P.3d at 119
    . We
    further stated that we review preserved, non-constitutional trial errors for
    harmless error, which requires reversal if the error substantially influenced the
    verdict or affected the fairness of the trial proceedings. 
    Id. at ¶
    12, 288 P.3d at 119
    .
    ¶75   In both cases, we determine first whether an error occurred. If it did, then
    we must determine, pursuant to a case-specific analysis, whether, applying the
    proper standard, the error impacted the proceedings. We do not, however, assess
    prejudice by reference to a different and independent error.
    ¶76   In contrast to the foregoing circumstance in which a defendant’s challenge
    for cause is erroneously denied (and in which proof of prejudice is nearly
    impossible), under the majority’s reasoning, when a prosecutor’s challenge for
    cause is improperly granted, then a defendant literally can never prove prejudice
    (absent, perhaps, evidence of bad faith).       This is because, by definition, the
    improperly removed juror would never have sat in judgment of the case and
    therefore the trial court’s erroneous ruling could not have deprived the defendant
    12
    of a fair and impartial jury. Maj. op. ¶ 25. Accordingly, contrary to the framework
    set forth in Hagos, we would never reach the question of whether such a trial error
    required reversal in a given case because, as a matter of law, it never would.
    ¶77   In light of the foregoing, the analytical regime for prejudice that the majority
    establishes in this case seems to result in a “heads I win, tails you lose” framework
    in favor of the prosecution. Under this framework, a defendant essentially can
    never establish prejudice, either from the erroneous denial of a defense challenge
    for cause or the erroneous grant of a prosecution challenge for cause.
    ¶78   Moreover, such a regime incentivizes prosecutors to challenge every
    debatable juror for cause because such challenges have no downside, given that
    erroneously granted challenges for cause have no consequences (and only a
    potential benefit) to the prosecution. This, in turn, effectively affords prosecutors
    a substantial voice in deciding the composition of a jury, while, at the same time,
    the majority’s opinion makes clear that criminal defendants have no right to such
    a voice.
    ¶79   In my view, such a result creates an unlevel playing field. In addition, the
    majority’s framework confirms Justice’s Hood’s observation in his partial
    dissenting opinion in People v. Novotny, 
    2014 CO 18
    , ¶ 31, 
    320 P.3d 1194
    , 1204
    (Hood, J., concurring in part and dissenting in part), that Novotny has moved us
    from a regime of automatic reversal in cases involving erroneously denied
    13
    challenges for cause to a regime of automatic affirmance in favor of the
    prosecution. With respect, I cannot subscribe to such a regime, and I would hope
    that, in an appropriate case, we will revisit the issue of prejudice and adopt a test
    that will give defendants in cases like this a full and fair opportunity to seek to
    establish prejudice in accordance with the case-specific, error/prejudice
    framework set forth in Hagos.
    III. Conclusion
    ¶80   For the foregoing reasons, I would conclude that the trial court abused its
    discretion in denying Vigil’s challenge for cause as to Juror C.A. and in granting
    the prosecution’s challenge for cause as to Juror D.K. Because Juror C.A. then sat
    on the jury, I would conclude that Vigil is entitled to a new trial.
    ¶81   Accordingly, I would reverse the judgment of the division below, and
    therefore, I respectfully dissent.
