    STATE v. EYRE
    Opinion of the Court
    accomplice-liability theory was erroneous and, if so, whether a
    convicted defendant‘s trial counsel provided ineffective assistance of
    counsel in failing to object to it.
    ¶2 Accurately conveying the required mental element of a
    crime in jury instructions is right up there in ―fundamental
    importance‖ alongside accurately determining the mental element.
    This importance is on display today as we conclude the defendant,
    Matthew Eyre, has been convicted and incarcerated based on an
    erroneous mens rea jury instruction—an instruction to which trial
    counsel should have objected. And this failure to object prejudiced
    Eyre as competing factual scenarios created the possibility that he
    was convicted without meeting the requisite mens rea. Accordingly,
    we reverse the court of appeals on the jury instruction issue, vacate
    Eyre‘s conviction, and remand for a new trial.
    BACKGROUND
    ¶3 On the morning of August 28, 2016, Daniel Simon and
    Natanni Xoumphonphackdy were parked in Simon‘s Dodge
    Challenger near 300 South 600 West. Nearby, Matthew Gordon Eyre,
    Jesse Ray Rakes, and Michael Sean Polk were sitting in a PT Cruiser.
    When Rakes noticed the Challenger, he allegedly told Eyre and Polk
    that he wanted to steal it and said he was going to ask for a jump
    start.
    ¶4 Rakes approached the Challenger and asked Simon for help
    jump-starting the Cruiser. Simon agreed to help and moved his
    vehicle so that it was ―nose to nose‖ in a ―V‖ shape to the Cruiser.
    ¶5 Simon then got out of his Challenger, lifted up the hood,
    and stood near his passenger window between the two vehicles.
    Rakes also propped up the hood of his car and joined Simon
    between the vehicles, and the two engaged in small talk. By this
    point, Eyre and Polk had also exited the Cruiser and began to look
    for jumper cables in the back of the Cruiser. Feeling like it was taking
    too long, Simon asked Rakes if they had cables. Rakes then lifted his
    shirt, flashing a pistol in his waistband, and said something to the
    effect of: ―You know what this is. We are taking everything.‖
    Notably, it is unclear if Rakes used the singular first-person pronoun
    ―I‖ or the plural ―we.‖ Rakes also threatened to ―pistol whip‖
    Xoumphonphackdy if she did not exit the Challenger.
    who don‘t speak legalese, mens rea means the mental element of a
    crime.

    Opinion of the Court
    ¶6 At this point, Xoumphonphackdy discretely handed Simon
    a pistol through the car window. As Simon attempted to back away
    from Rakes, Rakes pursued, ―drawing his gun in [Simon‘s]
    direction.‖ Simon then fatally shot Rakes. Eyre fled the scene. A
    collision occurred between the Challenger and Cruiser, which
    resulted in the Cruiser flipping over.
    ¶7 Eyre was arrested shortly after the incident and
    subsequently interviewed. No gun was found on him. In his
    interview, Eyre gave three accounts of the incident. Initially, Eyre
    denied being present, said he ―did not shoot anybody,‖ and said he
    did not ―see anybody get shot.‖ He said he only ―heard the sirens‖
    and ―heard a shot.‖ But then Eyre admitted to being in the car with
    Rakes and Polk when Rakes had asked Simon for a jump start. He
    also admitted to getting out of the car to look for cables upon Rakes‘s
    command. After finding no cables, Eyre said he walked around the
    car where he saw Rakes give chase to Simon before Simon shot
    Rakes.
    ¶8 After learning Rakes had died, Eyre alleged that it was
    Rakes‘s idea to steal Simon‘s car. He said that when Rakes initially
    saw the Challenger, Rakes told Eyre and Polk that he was going to
    take it. Eyre claimed that he told Rakes to leave them alone, that it
    was a ―dumb ass idea,‖ that he did not want to drive a stolen
    vehicle, and said, ―I won‘t do it.‖ Eyre said his refusal angered
    Rakes, who quickly dismissed Eyre‘s protest, stated he was going to
    ask for a jump start, and got out of the Cruiser. At this point, Eyre
    claimed that Rakes was ―running the show‖ and that he and Polk got
    out to look for cables in the back of the Cruiser. Eyre claimed that,
    immediately prior to the shooting, he walked up to Rakes and Simon
    and indistinctly heard Rakes say ―something‖ to Simon. He then saw
    Rakes give chase to Simon before Simon shot Rakes. When later
    asked about the ―plan,‖ Eyre stated that they had no plan.
    ¶9 In addition to Eyre‘s claims that he did not want to commit
    the robbery, there is conflicting testimony as to Eyre‘s actions during
    the robbery. Some testimony indicates that Eyre had approached
    Rakes and Simon between the cars and had also brandished a gun.
    But both Eyre and, notably, Xoumphonphackdy testified that Eyre
    did not engage in conversation with Simon or Rakes and did not
    possess or flash a gun. Xoumphonphackdy also testified that Eyre
    did not ―do anything to further [the] crime.‖ In addition to telling
    the police he was not armed during the robbery, Eyre claimed that
    he was unaware whether Rakes was armed.

    STATE v. EYRE
    Opinion of the Court
    ¶10 Eyre was charged as an accomplice to aggravated robbery, a
    first degree felony, under a theory of accomplice liability. The State
    argued that Eyre acted as an accomplice by allegedly pretending to
    look for jumper cables and by allegedly threatening Simon with a
    gun.
    ¶11 A jury trial was held in October 2017. At trial, the jury was
    given three instructions on accomplice liability. Defense counsel
    stipulated to the inclusion of these instructions.
    ¶12 The jury found Eyre guilty, and he was sentenced to an
    indeterminate prison term of 10 years to life. He timely appealed on
    multiple grounds. Relevant to our determination today, Eyre argued
    that jury Instruction No. 40 was erroneous and trial counsel was
    deficient in failing to object to it. The court of appeals affirmed the
    conviction, concluding ―that the instructions as a whole adequately
    instructed the jury on accomplice liability for aggravated robbery‖
    and that trial counsel‘s performance was thus not deficient. State v.
    Eyre, 
    2019 UT App 162
    , ¶ 21, 
    452 P.3d 1197
    . Eyre petitioned for a writ
    of certiorari, which this court granted. We have jurisdiction pursuant
    to Utah Code section 78A-3-102(3)(a).
    STANDARD OF REVIEW
    ¶13 ―On a writ of certiorari, we review the decision of the court
    of appeals, not that of the district court, and apply the same standard
    of review used by the court of appeals. We review the court of
    appeals‘ decision for correctness.‖ Prinsburg State Bank v. Abundo,
    
    2012 UT 94
    , ¶ 10, 
    296 P.3d 709
     (citation omitted). Further, ―[c]laims
    of erroneous jury instructions present questions of law that we
    review for correctness.‖ State v. Jeffs, 
    2010 UT 49
    , ¶ 16, 
    243 P.3d 1250
    .
    ¶14 When we review a jury verdict, we typically ―examine the
    evidence and all reasonable inferences in a light most favorable to
    the verdict.‖ State v. Heaps, 
    2000 UT 5
    , ¶ 2, 
    999 P.2d 565
    . This
    standard of review, however, is not helpful for us today, as we are
    not aware of which version of events the jurors accepted in reaching
    a guilty verdict, and all conflicting versions of the event could have
    led a reasonable juror to convict under an instruction that
    erroneously allows for a lesser mens rea. As such, we examine the
    evidence of all factual scenarios presented to the jury upon which the
    jury could have convicted under the erroneous instruction.

    ANALYSIS
    ¶15 Though Eyre argues for reversal based on three distinct
    legal theories, we conclude that we need only address one in order to
    dispose of this case: whether the court of appeals erred in concluding
    that trial counsel was not deficient in failing to object to jury
    Instruction No. 40.2 In short, we agree with Eyre‘s argument. We
    begin our analysis with an explanation of the mens rea requirements
    under a theory of accomplice liability. We then turn our analysis to
    Eyre‘s ineffective assistance of counsel claim, finding that no
    reasonable attorney would have agreed to the instruction and that
    trial counsel‘s deficient performance prejudiced Eyre.
    I.      ACCOMPLICE LIABILITY AND MENS REA
    ¶16 As anyone who has sat through the first day of an
    introductory course on criminal law knows, mens rea (or mental
    state) is typically a requisite of criminality. See, e.g., State v. Bird, 
    2015 UT 7
    , ¶ 14, 
    345 P.3d 1141
     (―A mens rea element is an essential
    element of [an] offense.‖ (alteration in original) (citation
    omitted)(internal quotation marks omitted)); State v. Barela, 
    2015 UT 22
    , ¶ 26, 
    349 P.3d 676
     (―[O]ur criminal code requires proof of mens
    rea for each element of a non-strict liability crime.‖); UTAH CODE
    § 76-2-102 (―Every offense not involving strict liability shall require a
    culpable mental state . . . .‖). But while most offenses require a
    showing of only one culpable mental state, accomplice liability
    requires at least two.
    ¶17 This branched mens rea requirement is codified in the Utah
    accomplice liability statute. The statute provides: ―Every person,
    acting with the mental state required for the commission of an
    offense who directly commits the offense, who solicits, requests,
    commands, encourages, or intentionally aids another person to
    engage in conduct which constitutes an offense shall be criminally
    liable as a party for such conduct.‖ UTAH CODE § 76-2-202. The first
    mens rea element—―[e]very person, acting with the mental state
    _____________________________________________________________
    2 Eyre argues in the alternative that the court of appeals erred in
    holding both (1) that trial counsel invited error in allowing the jury
    to access a video-recorded police interview of Eyre during
    deliberations; and (2) that trial counsel was not deficient in failing to
    ensure the police interview video-recording was excluded from jury
    deliberations. Because we dispose of the case on Eyre‘s jury
    instruction argument alone, we do not address these additional
    arguments.
    5
    STATE v. EYRE
    Opinion of the Court
    required for the commission of an offense‖—is a reference to the
    underlying crime (including any additional mens rea requirements
    associated with aggravating factors, if present). Id. The second—
    ―who . . . intentionally aids another person to engage in conduct
    which constitutes an offense‖—must be understood as a reference to
    the defendant‘s mental state solely in regard to ―aid[ing]‖ the
    commission of the underlying offense. Id.
    ¶18 A hypothetical helps to clarify this dual mens rea
    requirement. Imagine a defendant on trial for arson as an
    accomplice—while a co-felon set fire to a structure, this defendant
    drove the getaway car. The prosecution must show that the
    defendant‘s mental state meets the mens rea requirements of both the
    underlying crime and the accomplice liability statute. In our
    hypothetical, then, the prosecution must show that the defendant
    both intended that arson be committed (arson is a specific intent
    crime under Utah Code section 76-6-102(1)) and intentionally aided
    the co-felon in the commission of arson. Importantly, the two mens
    rea requirements are not always identical. If the defendant in our
    hypothetical were charged instead as an accomplice to reckless
    burning, for example, the mens rea of the underlying offense need
    only meet a recklessness standard, see id. § 76-6-104(1)(a), but the
    prosecution must still show that the defendant intentionally aided in
    the reckless burning offense.
    ¶19 Here, Eyre was charged with aggravated robbery under a
    theory of accomplice liability. Robbery requires a showing that ―the
    person unlawfully and intentionally takes or attempts to take
    personal property in the possession of another . . . .‖ Id. § 76-6-
    301(1)(a) (emphasis added).3 Aggravating factors include whether
    the defendant ―uses or threatens to use a dangerous weapon[,]
    causes serious bodily injury upon another[, or] takes or attempts to
    take an operable motor vehicle‖ and require a mens rea of
    recklessness at a minimum. Id. § 76-6-302(1); see id. § 76-2-102
    (providing that ―when the definition of the offense does not specify a
    culpable mental state and the offense does not involve strict liability,
    intent, knowledge, or recklessness shall suffice to establish criminal
    _____________________________________________________________
    3 Robbery may also be committed with a knowing mens rea under
    Utah Code section 76-6-301(1)(b). However, the prosecution
    proceeded only under subsection 301(1)(a) (which requires an
    intentional mens rea), and the jury was never presented with the
    option to convict under the lesser mens rea.

    Opinion of the Court
    responsibility‖).4 In order to find a defendant similarly situated to
    Eyre guilty of aggravated robbery as an accomplice, then, a jury
    must find that the defendant both intended that aggravated robbery
    be committed and that he intentionally aided the commission of the
    aggravated robbery. However, a jury cannot properly make this
    finding if it has not been given proper instructions to do so. This jury
    instruction issue comes packaged in an ineffective assistance of
    counsel claim, which we now address.
    II.   EYRE RECEIVED INEFFECTIVE ASSISTANCE OF
    COUNSEL
    ¶20 We now turn to discuss whether Eyre received ineffective
    assistance of counsel when trial counsel failed to object to Instruction
    No. 40. To prevail on an ineffectiveness claim, an appellant must
    show that: (1) counsel performed deficiently and (2) the deficient
    performance prejudiced the defense. Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984). Here, we first conclude that Instruction No. 40
    was erroneous as to the proper mens rea, and we conclude it was
    unreasonable not to object to it given the centrality of mens rea to
    Eyre‘s defense, thus constituting deficient performance. Then, in
    rounding out Eyre‘s ineffective assistance of counsel claim, we
    further conclude that the failure to object to the erroneous instruction
    prejudiced Eyre. As such, we reverse the determination of the court
    of appeals on this issue, vacate Eyre‘s conviction, and remand for a
    new trial.
    A. Jury Instruction No. 40 Was Erroneous, and Trial Counsel Performed
    Deficiently in Failing to Object to It
    ¶21 To determine whether trial counsel performed deficiently in
    failing to object to Instruction No. 40, we must decide if the
    instruction was, in fact, erroneous. This latter inquiry hinges on our
    application of State v. Jeffs, 
    2010 UT 49
    , 
    243 P.3d 1250
    , and its
    progeny. We first lay down the legal foundation of Strickland‘s
    deficiency prong and our jury instruction jurisprudence, then apply
    them to the facts before us, ultimately finding that Instruction No. 40
    _____________________________________________________________
    4 Because we conclude that the jury was improperly instructed
    with respect to the mens rea requirement for accomplice liability for
    robbery, we need not, and therefore do not, address the requisite
    mens rea to convert the robbery to aggravated robbery. In other
    words, as a matter of pure logic, you cannot get to aggravated
    robbery if there is no underlying simple robbery.
    7
    STATE v. EYRE
    Opinion of the Court
    was erroneous and that failing to object to it constituted deficient
    performance.
    1. Strickland‘s deficiency prong
    ¶22 The first prong of the Strickland test asks whether the
    defendant has shown ―that his counsel rendered a deficient
    performance in some demonstrable manner, which performance fell
    below an objective standard of reasonable professional judgment.‖
    Archuleta v. Galetka, 
    2011 UT 73
    , ¶ 38, 
    267 P.3d 232
    . (citation omitted);
    see Strickland, 
    466 U.S. at 687
    . This prong sets a high bar for
    defendants, given the ―strong presumption that trial counsel
    rendered adequate assistance and exercised reasonable professional
    judgment.‖ Archuleta, 
    2011 UT 73
     ¶ 39 (citation omitted). And it was
    with this presumption in mind, that we recently emphasized that
    ―[t]he Sixth Amendment ‗does not guarantee an errorless trial, and
    prevailing professional norms do not require perfection at trial.‘‖
    State v. Scott, 
    2020 UT 13
    , ¶ 36, 
    462 P.3d 350
     (citations omitted)
    (internal quotation marks omitted). Rather, as we put it in State v.
    Ray, 
    2020 UT 12
    , 
    469 P.3d 871
    , the ultimate question is always
    ―whether counsel‘s assistance was reasonable considering all the
    circumstances.‖ Id. ¶ 31 (emphasis added) (citation omitted). What‘s
    more, there is no such thing as per se deficient performance. Id. And
    with respect to the specific issue at hand, Ray makes plain that the
    failure to ―object[] to an error‖ in an instruction ―does not
    automatically render counsel‘s performance deficient.‖ Id.; see also id.
    ¶ 36 (―Here, that means we must ask whether defining indecent
    liberties was sufficiently important under the circumstances that
    counsel‘s failure to argue for a clarifying jury instruction fell below
    an objective standard of reasonableness.‖).
    2. Jury Instruction No. 40 was erroneous
    ¶23 We have previously opined on erroneous jury instructions
    in the context of accomplice liability. In Jeffs, we stressed the
    importance of presenting the jury with instructions that clearly
    establish the dual mens rea requirements under the accomplice
    liability statute. 
    2010 UT 49
    , ¶¶ 39–52. In that case, the defendant, a
    leader of the Fundamentalist Church of Jesus Christ of Latter-Day
    Saints (FLDS), was charged and convicted of two counts of rape as
    an accomplice—the defendant had proselytized the teachings of the
    FLDS church (including plural marriage), performed a marriage
    between a fourteen-year-old girl and an older cousin (Allen Steed),
    and forced the girl to remain in the marriage despite her pleas. 
    Id.
    ¶¶ 3–13. Thereafter, the girl was repeatedly raped by her cousin. 
    Id.
    8
    Cite as: 
    2021 UT 45
    Opinion of the Court
    ¶ 13. At trial, the jury was provided with an instruction regarding
    Jeff‘s accomplice liability, which required the jury to find that
    1. [T]he defendant, Warren Jeffs:
    a. intentionally, knowingly, or recklessly solicited,
    requested, commanded, or encouraged another—
    [i]. to have sexual intercourse
    ii. with [the victim] without consent; or
    b. intentionally aided another—
    [i]. to have sexual intercourse
    ii. with [the victim] without consent; and
    2. Allen Steed had sexual intercourse with [the victim]
    without consent.
    Id. ¶ 41. Notwithstanding the unsavory details of the crime, this court
    found the instruction ―confusing with respect to the issue of intent,‖
    even though the instruction ―did incorporate the phrase
    ‗intentionally aided.‘‖ Id. ¶ 51. The problem with the instruction was
    that, ―even if Jeffs never intended for Steed to rape [the victim], the
    jury instruction allowed for the possibility that he would be found
    guilty simply because he intentionally performed the marriage
    ceremony and the existence of the marriage aided Steed in raping
    [the victim].‖ Id. ¶ 52. Such a finding would be in error. Id.; see also
    State v. Bird, 
    2015 UT 7
    , ¶ 14, 
    345 P.3d 1141
     (holding that ―failure to
    instruct the jury as to the required mens rea, when it is an element of
    the crime, is reversible error‖).
    ¶24 Jeffs is not a case about deficient performance, but it
    nonetheless highlights this court‘s perspective on dual mens rea jury
    instructions. Jeffs stands for the proposition that a jury instruction
    regarding mens rea in the accomplice liability setting is erroneous if it
    inspires confusion such that there is a possibility a jury would not
    apply both mens rea requirements or would apply a lesser mens rea
    than is required.
    ¶25 Since Jeffs, we have consistently applied its reasoning. Most
    recently, in State v. Grunwald, we agreed with the court of appeals‘
    determination that a jury instruction was erroneous because the
    instruction ―permitted the jury to convict [the defendant as an
    accomplice] based on a reckless mental state‖ when the underlying
    offense—aggravated       murder—required       a     ―knowing‖     or
    ―intentional‖ mental state. 
    2020 UT 40
    , ¶¶ 33–34, 
    478 P.3d 1
    . And we
    9
    STATE v. EYRE
    Opinion of the Court
    agreed with the court of appeals that failing to object to the
    erroneous instruction constituted deficient performance. Id. ¶ 20.5
    ¶26 Just as in Jeffs and Grunwald, the instructions provided to the
    jury that ultimately convicted Eyre were erroneous. Instruction No.
    40 provided: ―If you find beyond a reasonable doubt that: (1) the
    defendant intentionally, (2) solicited, requested, commanded,
    encouraged, or intentionally aided another to commit the offense,
    AND (3) the offense was committed, then you can find the
    defendant guilty of that offense.‖ And just as in Jeffs, we find
    ourselves asking: ―intentionally . . . in regard to what?‖ 
    2010 UT 49
    ,
    ¶ 44. This instruction has no explanation as to the mens rea
    requirement of the underlying offense. And while aggravated
    robbery requires an intentional mental state with regard to the actual
    robbery,6 see UTAH CODE § 76-6-301(1)(a), the use of the word
    _____________________________________________________________
    5 In State v. Barela, we contemplated the adequacy of a mens rea
    jury instruction for rape. 
    2015 UT 22
    , ¶ 2, 
    349 P.3d 676
    . Like
    accomplice liability, the elements of rape include a dual mens rea
    requirement—a requirement as to the sexual intercourse and a
    separate requirement as to the victim‘s nonconsent. Id. ¶ 26. The
    instruction in Barela provided: ―1. The defendant . . ., 2. Intentionally
    or knowingly; 3. Had sexual intercourse with [the victim]; 4. That
    said act of intercourse was without the consent of [the victim].‖ Id.
    ¶ 13. Much like in Jeffs, this instruction left unclear whether
    ―intentionally or knowingly‖ also applied to the nonconsent element
    and, in fact, ―implied that the mens rea requirement . . . applied only
    to the act of sexual intercourse.‖ Id. ¶ 26. We determined, then, that
    the instruction‘s ―implication was error.‖ Id.
    6  Recall that the prong of the robbery statute that the State
    proceeded under in its case against Eyre requires intentional
    conduct, while the aggravating factors require an additional mens rea
    requirement of recklessness. See supra ¶ 19. Whether Eyre meets this
    recklessness standard for the aggravating factors is not at issue
    today. In contemplating the accuracy of jury instructions as a
    precursor to our Strickland analysis, we first address whether the
    instructions sufficiently instructed the jury to determine whether
    Eyre had the requisite intent that robbery be committed and whether
    he had the requisite intent to aid Rakes in the commission of the
    robbery. They did not. And given the import of mens rea to Eyre‘s
    defense, we must then determine whether it was objectively
    (continued . . .)
    10
    Cite as: 
    2021 UT 45
    Opinion of the Court
    ―intentionally‖ in part (1) of Instruction No. 40 is situated such that it
    is coupled with ―solicited, requested, commanded, encouraged‖ in
    part (2) and not with the underlying offense language of part (3),
    thus permitting the jury to convict without determining whether
    Eyre had the requisite mens rea for the underlying aggravated
    robbery offense. See State v. Barela, 
    2015 UT 22
    , ¶ 26, 
    349 P.3d 676
    (finding that, ―by coupling the mens rea requirement directly with
    [one element of the offense], and by articulating the [other element]
    without any apparent counterpart requirement of mens rea,‖ the
    instruction erroneously conveyed that the ―mens rea requirement . . .
    applied only to the‖ first element). This instruction was therefore in
    error.
    ¶27 The State argues that even if Instruction No. 40 were
    erroneous (and it is), it was cured by Instructions Nos. 39 and 41.
    Instruction No. 39 provided in relevant part:
    Every person, acting with the mental state required
    for the commission of the offense who directly
    commits the offense, who solicits, requests,
    commands, encourages, or intentionally aids another
    person to engage in conduct which constitutes an
    offense shall be criminally liable as a party for such
    conduct.
    And Instruction No. 41 provided in relevant part:
    Prior knowledge that a crime is about to be
    committed or is being committed does not make a
    person an accomplice, and thereby does not subject
    them to criminal prosecution unless that person has
    the mental state required to commit the crime and he
    solicits, requests, commands, encourages, or
    intentionally aids in the perpetration of the crime.
    Indeed, these two instructions more clearly define the dual mens rea
    requirements under an accomplice liability theory because they
    provide that the defendant must have ―the mental state required for
    the commission of the offense‖ (or ―the mental state required to
    commit the crime‖) and must ―intentionally aid[]‖ the commission of
    the offense. But when read in conjunction with Instruction No. 40,
    these instructions do not cure No. 40‘s error but rather instill more
    reasonable, in light of the circumstances of Eyre‘s defense, not to
    object to the erroneous instructions. See infra part II.A.3.
    11
    STATE v. EYRE
    Opinion of the Court
    confusion. Though correct, Instructions Nos. 39 and 41 contradict
    Instruction No. 40, which itself does not require the defendant to
    have had the requisite mental state for the underlying offense. See
    Francis v. Franklin, 
    471 U.S. 307
    , 322 (1985) (―Language that merely
    contradicts and does not explain a constitutionally infirm instruction
    will not suffice to absolve the infirmity. A reviewing court has no
    way of knowing which of the two [or more] irreconcilable
    instructions the jurors applied in reaching their verdict.‖).
    3. Trial counsel performed deficiently
    ¶28 Our return to plain language of Strickland in Scott, 
    2020 UT 13
    , ¶ 36, and Ray, 
    2020 UT 12
    , ¶ 31, does not support the categorical
    approach to mens rea instructions that we once may have indicated.
    See, e.g., Barela, 
    2015 UT 22
    , ¶ 27 (―[N]o reasonable lawyer would
    have found an advantage in understating the mens rea requirement
    . . . . There is only upside in a complete statement of the requirement
    of mens rea . . . .‖). Instead, we adjudge counsel‘s conduct ―on the
    facts of the particular case.‖ Ray, 
    2020 UT 12
    , ¶ 31 (citation omitted).
    ¶29 Armed now with our jurisprudence regarding mens rea
    instructions for accomplice liability and the Strickland standard—as
    explained in Scott and Ray—we assess counsel‘s failure to object to
    jury Instruction No. 40 in the present case. We start with determining
    whether the deficiency in the instruction ―was sufficiently important
    under the circumstances that counsel‘s failure to argue for a
    clarifying jury instruction fell below an objective standard of
    reasonableness.‖ Id. ¶ 36. In this case, we conclude the deficiency in
    jury Instruction No. 40 was important and that failure to object or
    argue for a clarifying jury instruction did fall below an objective
    standard of reasonableness. Additionally, we look at whether the
    alleged error in instruction is germane or ―pertinent to‖ the defense
    advanced at trial. See id. ¶ 38.
    ¶30 Instruction No. 40 was erroneous, and the confusion
    engendered by the contradiction between Instruction Nos. 39, 40, and
    41 further supports this conclusion. Having concluded that both
    Instruction No. 40 and the instructions as a whole were erroneous for
    understating or inaccurately portraying the mens rea requirements for
    aggravated robbery as an accomplice, we conclude that trial
    counsel‘s failure to object to Instruction No. 40 constituted deficient
    performance. We see neither a reasonable strategy nor one offered
    that could explain trial counsel‘s failure to object, given that Eyre‘s
    defense hinged on a lack of intentionality as to the robbery. In the
    circumstances of this particular case, where mens rea is at issue and
    12
    Cite as: 
    2021 UT 45
    Opinion of the Court
    the erroneous instruction allowed the jury to convict on a lesser
    showing, any reasonable lawyer would have objected to the
    inaccurate and incomplete statement.7
    B. Trial Counsel’s Deficient Performance Prejudiced Eyre
    ¶31 Though Eyre has cleared the first hurdle in his ineffective
    assistance of counsel claim, the Strickland test requires him to clear
    one more. To prevail on an ineffective assistance of counsel claim, an
    appellant must also ―present sufficient evidence to support ‗a
    reasonable probability that, but for counsel‘s unprofessional errors,
    the result of the proceeding would have been different.‘‖, 
    2011 UT 73
    , ¶ 40, 
    267 P.3d 232
     (quoting Strickland, 
    466 U.S. at 694
     (additional
    citations omitted)). We refer to this requirement as the prejudice
    prong. See, e.g., Grunwald, 
    2020 UT 40
    , ¶ 21.
    _____________________________________________________________
    7 We take this opportunity to recommend that trial courts apply
    our Model Utah Jury Instruction on Party Liability, which accurately
    and clearly portrays the dual mens rea requirement. It provides:
    A person can commit a crime as a ―party to the
    offense.‖ In other words, a person can commit a
    criminal offense even though he or she did not
    personally do all of the acts that make up the offense.
    Before a person may be found guilty as a ―party to the
    offense,‖ you must find beyond a reasonable doubt
    that:
    1. The person had the mental state required to commit
    the charged offense;
    AND
    2. The person:
    a. directly committed the offense; or
    b. intentionally, knowingly, or recklessly solicited,
    requested, commanded or encouraged another
    person to commit the charged offense; or
    c. intentionally aided another person to commit
    the charged offense;
    AND
    3. The charged offense was committed either by that
    person or another person.
    MUJI 2d CR403B (amended 2018) (citing UTAH CODE ANN. § 76-2-
    202). This instruction must be used in concert with model jury
    instruction CR403A, which defines the elements of the underlying
    offense.
    13
    STATE v. EYRE
    Opinion of the Court
    ¶32 Our recent jurisprudence provides ample guidance in
    determining prejudice in this particular context. ―When applying
    Strickland‘s prejudice analysis in the context of erroneous jury
    instructions, we must determine whether there is a reasonable
    probability the jury would not have convicted the defendant if the
    jury instructions had been correct.‖ Id. ¶ 22. We have further
    clarified that
    [a] reasonable probability ―is a probability sufficient
    to undermine [our] confidence in the outcome.‖ To
    determine whether there is a reasonable probability of
    a different outcome, we must ask ourselves two
    questions: (1) did the error in the jury instructions
    create the possibility that the jury convicted the
    defendant based on factual findings that would not
    have led to conviction had the instructions been
    correct? And, (2) if so, is there a reasonable probability
    that at least one juror based its verdict on those
    factual findings?
    Id. (second alteration in original) (citation omitted). Importantly,
    we‘ve noted that the term ―‗factual findings‘ does not refer to the
    jury‘s ultimate determinations‖ but rather ―to the potential factual
    scenarios the jurors could have accepted while listening to the
    parties‘ respective version of the relevant events of the case.‖ Id. ¶ 22
    n.21. After identifying the factual scenarios under the first Grunwald
    factor, ―we must determine whether there is a reasonable probability
    that, based on the totality of the evidence, a juror convicted the
    defendant based on . . . . an accepted version of events that would
    not have led to a conviction with a correct jury instruction.‖ Id. ¶ 26.
    ¶33 This guidance is particularly helpful when, as here, the
    parties have provided very differing versions of the event regarding
    an alleged accomplice‘s mental state. In Grunwald, for example, the
    defendant claimed she was coerced at gunpoint to aid in a co-felon‘s
    offense, id. ¶ 9, while the State argued the defendant participated
    willingly and intentionally. Id. ¶ 11. A juror might accept one version
    over the other, or ―conclude[] that the truth fell somewhere in
    between.‖ Id. ¶ 22 n.21. And
    [i]f a juror determined, based on the version of events
    he or she accepted as true, that [the defendant] acted
    recklessly (but not knowingly or intentionally), then
    the jury would not have convicted [her] had the jury
    been given a correct jury instruction—an instruction
    14
    Cite as: 
    2021 UT 45
    Opinion of the Court
    that did not       permit    a    conviction   based    on
    recklessness.
    
    Id.
     Put simply, if: (1) competing facts regarding a defendant‘s mens
    rea exist; (2) there‘s a reasonable probability the juror based their
    conviction on a party‘s version of events that would not have
    otherwise resulted in a conviction under proper instructions; and
    (3) a jury instruction fails to instruct the jury on the requisite mens rea
    to convict, then the defendant has been prejudiced by the instruction
    and trial counsel‘s failure to object to it.
    ¶34 We have exactly that situation before us today. Eyre and the
    State recounted conflicting versions of the deadly robbery. Eyre, in
    one of his versions, claimed he disagreed with Rakes‘ plan to steal
    the Dodge Challenger, had even tried to talk Rakes out of it, was not
    engaged in conversation with Rakes and Simon when Rakes flashed
    his pistol at Simon and Xoumphonphackdy, was not himself armed,
    and was not aware whether Rakes was armed. This factual scenario
    creates the reasonable possibility that Eyre did not intend for the
    robbery to be committed and thus was not searching for jumper
    cables in the back of the PT Cruiser with the intent to effectuate the
    robbery, but rather was doing so to buy time or to appease or mollify
    Rakes, who had insisted on committing the robbery despite Eyre‘s
    alleged pushback.8
    ¶35 This version of events establishes, at most, Eyre‘s
    recklessness as to the commission of the aggravated robbery, thus
    falling below the required intentional mens rea of that offense. And
    while the State argues Eyre flashed a gun alongside Rakes, Eyre‘s
    account is supported by Xoumphonphackdy, a victim of the robbery,
    who stated that Eyre remained at the back of the PT Cruiser and
    ―didn‘t do anything to further th[e] crime.‖ And so, given that Eyre‘s
    _____________________________________________________________
    8  We do not mean to imply that a defendant is always off the
    accomplice liability hook when they allege to have known of a plan
    to commit a criminal offense but did not adhere to it. Here, in Eyre‘s
    telling, he expressed that he did not want to go through with it, thus
    leaving open the possibility that Eyre did not have the requisite
    intent. But if the underlying crime requires a lower mens rea, such as
    reckless burning, see supra ¶ 18, an accomplice defendant claiming to
    know of the plan but to have digressed from it out of a desire that
    the crime not be committed will nonetheless be liable as an
    accomplice because they have met the requisite recklessness mens
    rea.
    15
    STATE v. EYRE
    Opinion of the Court
    account creates a reasonable possibility that he did not intend for the
    aggravated robbery to occur, which is further supported by
    Xoumphonphackdy‘s account, we conclude there was a reasonable
    probability that at least one juror voted to convict based on this
    factual scenario, which ―would have been insufficient to sustain a
    conviction had the instruction been given correctly.‖ Id. ¶ 27. As
    such, we find there is a ―reasonable probability the jury would not
    have convicted the defendant if the jury instructions had been
    correct.‖ Id. ¶ 22. Trial counsel‘s deficient performance in failing to
    object to the instruction thus prejudiced Eyre.
    CONCLUSION
    ¶36 Jury Instruction No. 40 was erroneous—it failed to
    accurately and clearly instruct the jurors on the dual mens rea
    requirement under an accomplice liability theory. Moreover, related
    instructions did not cure No. 40‘s error but rather served to inject
    more confusion into the instructions. As such, we conclude that the
    court of appeals erred in holding that the instructions were
    sufficient.
    ¶37 And having concluded the instructions were erroneous, we
    also conclude that Eyre‘s right to effective assistance of counsel was
    violated. This case is characterized by multiple accounts and
    conflicting facts regarding Eyre‘s mental state during the armed
    robbery. While we do not opine on the veracity of either party‘s
    version of events, we recognize there is a reasonable probability that
    the erroneous instruction impermissibly allowed at least one juror to
    vote to convict Eyre despite believing that Eyre did not intend for the
    robbery to occur. Trial counsel should have recognized this
    possibility and should have objected, but did not. And this failure to
    cure the erroneous instruction prejudiced Eyre. Because both prongs
    of the Strickland test are satisfied, we reverse the court of appeals on
    the jury instruction issue, vacate Eyre‘s conviction, and remand for a
    new trial.
