    JUSTICE PEARCE, opinion of the Court:
    INTRODUCTION
    ¶1 After hours of unsuccessful attempts to calm his four-year-
    old who was throwing a series of temper tantrums, Nathan Baize
    spanked his son three times. During the tantrums, Baize’s son kicked
    Baize and hit him in the face. The child also kicked and punched his
    grandmother. Baize later told a police detective that he spanked his
    son as a “last resort.” Evidence at trial showed that Baize struck his
    son with enough force to leave bruises in the shape of a handprint on
    the child’s bottom that were visible two days later.
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    ¶2 Bountiful City charged Baize with child abuse under Utah
    Code section 76-5-109(3)(c). That provision makes it a class C
    misdemeanor to “inflict[] upon a child physical injury” with
    “criminal negligence.” The district court convicted Baize after a
    bench trial.
    ¶3 Baize appealed and argued before the court of appeals that
    the district court had misconstrued and misapplied the law.
    Specifically, Baize argued that the district court had failed to
    properly consider whether Baize’s discipline could be considered
    “reasonable discipline” by a parent—conduct which is exempted
    from the statute’s reach under certain circumstances. Bountiful City v.
    Baize, 
    2019 UT App 24
    , ¶¶ 17–21, 
    438 P.3d 1041
    ; see also UTAH CODE
    § 76-5-109(8). Baize alternatively argued that his trial counsel
    rendered ineffective assistance of counsel by failing to raise the
    “reasonable discipline” defense. Baize, 
    2019 UT App 24
    , ¶ 16. The
    court of appeals rejected both of Baize’s arguments and affirmed
    Baize’s conviction. 
    Id.
     ¶¶ 30–31.
    ¶4 Baize petitioned for certiorari. Before us, Baize contends the
    court of appeals erred by misconstruing and misapplying the law in
    a way that “essentially establishes a rule that any spanking by a
    parent that leaves a bruise” on the child constitutes “child abuse
    under the Statute.”
    ¶5 We disagree with Baize about what the court of appeals
    held. The court of appeals correctly recognized that although a
    parent “may be convicted of child abuse when he causes physical
    injury to a child, including bruising,” the statute also provides
    parents with a defense if the injury was not “serious” and “the
    conduct in question constituted reasonable discipline.” Baize, 
    2019 UT App 24
    , ¶¶ 20–21; see also UTAH CODE § 76-5-109(3), (8); id. § 76-2-
    401.
    ¶6 Even though we endorse the court of appeals’ construction
    of the statute, we conclude the court of appeals erred in determining
    it was “clear from the record” that the district court applied and
    correctly analyzed the statute’s “reasonable discipline” provision.
    Baize, 
    2019 UT App 24
    , ¶¶ 22–23. We do not see the same clarity that
    the court of appeals did. We therefore vacate Baize’s conviction and
    remand to the district court to enter findings about whether the
    discipline that Baize meted upon his son was “reasonable
    discipline.”

    Opinion of the Court
    BACKGROUND
    Facts1
    ¶7 Baize had his four-year-old son (Son) for weekend parent-
    time. See Bountiful City v. Baize, 
    2019 UT App 24
    , ¶ 2, 
    438 P.3d 1041
    .
    Son acted up and threw multiple temper tantrums. 
    Id.
     ¶¶ 3–4. Son’s
    mother (Mother) testified that Baize had emailed her and that the
    emails indicated Son had been “yelling and screaming.” See id. ¶ 3.
    Son “was saying terrible things, he was going to hurt people. He was
    mad. He wanted to go home. He was upset. Completely distraught.”
    Id. ¶ 3. A Bountiful City Police Department detective (Detective)
    similarly testified that, based on his interview with Baize, Son was
    “out of control,” “throwing temper tantrums, using foul language,
    [and] saying that he wanted [Baize] dead. . . .”
    ¶8 One of Son’s tantrums occurred in a grocery store parking
    lot. According to Detective, when Baize came out of the store, Baize
    found Son “kicking and punching his grandmother,” who was with
    Son in a parked car. Son also repeatedly “jump[ed] up and down,
    ‘slamming his rear end on the bottom of the car seat.’” Id. (quoting
    Detective). The tantrum continued for approximately an hour until
    Son calmed down enough that Baize could strap the child into his
    car seat. Id.
    ¶9 But the reprieve from Son’s tantrums proved temporary.
    Once they returned home, Son resumed fighting with Baize. Id. ¶ 5.
    Baize told Detective that he tried various disciplinary interventions.
    This included talking to Son, putting him in a corner, and
    “everything but physical force.” Finally, “the only thing . . . [Baize]
    thought would help would [be to] spank [Son].” Baize then put Son
    “over his knee and warned him that he was going to be spanked
    unless he calmed down.” Baize, 
    2019 UT App 24
    , ¶ 5. Son “continued
    to swear and tell Baize that he hated him.” 
    Id.
     Baize then spanked
    Son on his bottom. Son continued his tantrum. Baize warned Son
    again. And then he spanked Son a second and third time. 
    Id.
     Baize
    told Detective the spanking was a “last resort.” 
    Id.

    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    ¶10 The morning after the incident, Baize called Mother and
    asked that she pick up Son hours earlier than planned. Id. ¶ 6. That
    evening, Mother noticed bruising on Son’s bottom. Id. Son told
    Mother what had happened. Id. Mother then called the Division of
    Child and Family Services (DCFS). Id.
    ¶11 The following day (two days after the incident), a DCFS
    investigator came to see Mother and advised her to call the police. Id.
    ¶ 8. She did. That same day, Mother took photographs of the
    bruising. Id. ¶ 7.
    ¶12 Thereafter, Detective arranged for Son to be interviewed at
    the Children’s Justice Center. Id. ¶ 8. After seeing Mother’s
    photographs and hearing Son’s interview, Detective interviewed
    Baize. Id.
    District Court Arguments and Conviction
    ¶13 Bountiful City charged Baize with a class C criminal
    misdemeanor of child abuse under Utah Code section 76-5-109(3)(c)2
    for “inflict[ing] upon a child physical injury”3 with “criminal
    2 We cite the current version of the statute, as there have been no
    substantive changes to the subsections pertinent to the allegations in
    this case since the incident occurred in 2016. Although portions of
    section 76-5-109 of the Utah Code were amended in 2017, those
    amendments affected only the definition of “serious physical injury,”
    specifically relating to impediments to a child’s breathing or blood
    circulation or unconsciousness. See H.B. 17, 
    2017 Utah Laws 2198
    –
    2220 (amending UTAH CODE § 76-5-109(1)(f)(ii)(I) and adding § 76-5-
    109(1)(f)(ii)(K)). The definitions of “physical injury,” UTAH CODE
    § 76-5-109(1)(e), and the charged offense, id. § 76-5-109(3)(c), are the
    same in the current code as they were in 2016.
    3  The statute defines “physical injury” as:
    an injury to or condition of a child which impairs the
    physical condition of the child, including: (i) a bruise or
    other contusion of the skin; (ii) a minor laceration or
    abrasion; (iii) failure to thrive or malnutrition; or (iv)
    any other condition which imperils the child’s health or
    welfare and which is not a serious physical injury. . . .

    negligence.”4 Id. ¶ 10. Baize pled not guilty and requested a bench
    trial. Id.
    ¶14 Mother testified that she saw “bruising, fingerprints . . . lines
    on [Son’s] bottom, bruising . . . [and] little spots on his bottom that
    are bruised.” Id. ¶ 7. Mother’s photograph of the bruising was
    introduced into evidence without objection. Mother testified that the
    images accurately portrayed Son’s bruising. Id.
    ¶15 Detective similarly testified that the photograph depicted
    bruising in the shape of “a finger or a handprint,” as well as other
    bruising and redness consistent with diaper rash. Id.¶ 9. Detective
    presumed that Son “slamming his butt up and down into the car
    seat” was the cause of the additional bruising. Detective testified that
    he was unaware of any reports that Son required medical attention
    for the redness and bruising. Baize, 
    2019 UT App 24
    , ¶ 9. Mother
    confirmed that Son required no medical attention.
    ¶16 Baize’s trial counsel argued that spanking Son “was not a
    gross deviation from the standard of care based on [the] facts [and]
    specific evidence that [was introduced].”5 Id. ¶ 12 (second and third
    alteration in original). He also argued that Baize “did not take an
    unjustifiable risk to cause bruising.” Id. Baize’s counsel emphasized
    the circumstances leading up to the incident, including that Son
    “kicked and punched” his grandmother, caused bruising to himself
    by jumping up and down in his car seat, and engaged in
    “[t]hreatening behavior, hitting, yelling.” The spanking, counsel
    explained, was the only tool Baize had left “as a parent” after
    exhausting other options. Baize, 
    2019 UT App 24
    , ¶ 12. Moreover, it
    was done in a “controlled manner,” was “not done out of anger,”
    4   Under Utah Code section 76-2-103(4):
    A person engages in conduct . . . [w]ith criminal
    negligence or is criminally negligent with respect to
    circumstances surrounding his conduct or the result of
    his conduct when he ought to be aware of a substantial
    and unjustifiable risk that the circumstances exist or the
    result will occur. The risk must be of a nature and
    degree that the failure to perceive it constitutes a gross
    deviation from the standard of care that an ordinary
    person would exercise in all the circumstances as
    viewed from the actor’s standpoint.
    5   Baize’s trial counsel does not represent Baize on appeal.
    5
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    was designed “to help the child calm down and get under control,”
    and stopped when Baize “thought that was enough.” 
    Id.
    ¶17 Baize’s trial counsel never expressly argued that Baize’s
    spanking was “reasonable discipline.” Nor did he expressly argue it
    fit into any other defense or justification in Utah Code section 76-5-
    109(8)6 or 76-2-401.7 Instead, Baize’s trial counsel argued that the
    spanking, under the circumstances, “was not a gross deviation from
    the standard of care” and was not “an unjustifiable risk.” Baize, 
    2019 UT App 24
    , ¶ 12.
    ¶18 The City acknowledged that it is not “illegal or wrong” for
    parents to discipline their children, including by spanking. Id. ¶ 11.
    Nevertheless, the City repeatedly pushed for a rule that “when you
    spank a child to the point where there is physical injury . . . you
    come to a Class C misdemeanor child abuse.” Id. The law “clearly
    states,” the City asserted, that it “is a violation when you leave
    physical injury [and] that’s always going to be a gross deviation.
    Parents aren’t supposed to leave physical injury on their children.”
    ¶19 The City reasoned that “any parent,” including Baize,
    “should be aware that there may be bruising, that they may injure a
    child. They are putting their hands on a child. It’s obvious to all of us
    that there’s a risk that they may injure the child if they spank the
    child too hard.” The City explained that Baize could have remained
    within the confines of the law “[i]f he was being extra cautious” and
    “spanked him much more lightly to the point where there was no
    6   Utah Code section 76-5-109(8) provides:
    A person is not guilty of an offense under this section
    for conduct that constitutes: (a) reasonable discipline or
    management of a child, including withholding
    privileges; (b) conduct described in Section 76-2-401; or
    (c) the use of reasonable and necessary physical
    restraint or force on a child: (i) in self-defense; (ii) in
    defense of others; (iii) to protect the child; or (iv) to
    remove a weapon in the possession of a child. . . .”
    7  Utah Code section 76-2-401(1)(c) provides that the “defense of
    justification may be claimed . . . when the actor’s conduct is
    reasonable discipline of minors by parents, guardians, teachers, or
    other persons in loco parentis. . . .” This defense is “not available if
    the offense charged involves causing . . . serious physical injury. . . .”

    Opinion of the Court
    bruising.” The City concluded: “it’s a matter of degree. And this is
    the lowest degree. It’s just stepping over the line of the criminal code
    instead of parenting.”
    ¶20 The City repeatedly argued that Son’s “behavior really
    doesn’t matter in the scheme of things.” “It comes down to the fact
    that while disciplining his child [Baize] left a handprint on [Son],
    bruised him. . . . That’s it.” Baize, 
    2019 UT App 24
    , ¶ 11.
    ¶21 The district court began its analysis by reading aloud the
    definition of the relevant mens rea for the class C misdemeanor at
    issue—“criminal negligence.” See UTAH CODE § 76-2-103(4). The
    court read: “[a] person engages in conduct with criminal negligence
    . . . when he ought to be aware of [a] substantial and unjustifiable
    risk that . . . the result would occur” and when that risk is of a
    “degree” that failure to perceive it “constitutes [a] gross deviation of
    the standard of care that an ordinary person would exercise in all of
    the circumstances,” as viewed from the defendant’s standpoint.
    ¶22 The district court again displayed its fixation with the mens
    rea when it interrupted the City’s closing argument. The prosecutor
    had begun to say that, in this case, “the focus of course should be
    . . . .” The court interjected: “The mens rea.” The City then added:
    “The mens rea and the injuries.” Neither the court nor the City
    mentioned the reasonableness or unreasonableness of the parental
    discipline.
    ¶23 Following both parties’ presentations and closing
    arguments, the district court clarified what it perceived to be the
    statutory provisions relevant to the crime charged:
    The statute involved as we all understand is [Utah
    Code section] 76-5-109. Any person who inflicts upon a
    child physical injury—I’m just reading the pertinent
    part—is guilty of an offense as follows. Part C, if done
    with criminal negligence the offense is a Class C
    misdemeanor. And again, I previously read the
    definition of criminal negligence. I won’t read that
    again. It is the lowest of the four mens rea standards
    that are recognized in Utah State law.
    I further note that physical injury is defined under
    [section] 76-5-109. And I’ll just read a small part of that.
    “Physical injury means an injury to or a condition of
    the child which impairs the physical condition of the
    child, including, 1, a bruise or other contusion of the
    skin.” There are other—there is a further definition of
    7
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    physical injury, but I’m just going to stop there for
    purposes of this case.
    Baize, 
    2019 UT App 24
    , ¶ 13 (emphases added). The district court did
    not, in its narration of the “pertinent part[s]” of the statute, read
    from or cite any defense or justification in sections 76-5-109(8) or 76-
    2-401 of the Utah Code. Nor did it use the term “reasonable
    discipline” in its analysis. The court did acknowledge that “a parent
    should be allowed to discipline his children in an appropriate way.”
    Id. ¶¶ 13, 22. But the court also clarified, “I think [the City] has it
    right. I think it’s a matter of degree.”
    ¶24 The court then found that “the level of contusion, the
    bruising on the buttocks of the child” indicated that the spanking
    “was just too hard,” and therefore the “discipline was a gross
    deviation from the standard of care that an ordinary person would
    exercise.” Baize, 
    2019 UT App 24
    , ¶ 13. Based on that finding and
    “based on the testimony of the two witnesses,” the court concluded
    there was “proof beyond a reasonable doubt” for convicting Baize of
    a class C misdemeanor, for “inflicting physical injury on a child with
    criminal negligence.” 
    Id.
    ¶25 The district court sentenced Baize to ninety days in Davis
    County Jail plus a $750 fine but suspended both and ordered Baize
    to serve ten days in jail with twelve months’ probation.
    The Court of Appeals Affirms
    ¶26 With the assistance of new counsel, Baize appealed his
    conviction, raising two issues before the court of appeals. First, Baize
    argued that “his trial counsel deprived him of his right to effective
    assistance of counsel by failing to bring the [reasonable discipline]
    justification defense identified in Utah Code section 76-2-401.” Baize,
    
    2019 UT App 24
    , ¶ 27. Second, “Baize claim[ed] that the district court
    misinterpreted and misapplied Utah Code section 76-5-109,” by
    either failing to analyze the “reasonable discipline” defense
    provided in subsection 8, id. ¶¶ 15, 21, or by conducting such an
    analysis without due consideration of certain common law factors
    Baize deemed necessary, including the “age, condition and
    disposition of the child” and the “good faith” of the parent. Id. ¶ 24.
    In his court of appeals briefs, Baize acknowledged that his statutory
    construction argument was raised for the first time on appeal,
    arguing that the court of appeals should nevertheless address it
    under the “plain error” exception to preservation rules.
    ¶27 The court of appeals rejected both of Baize’s arguments and
    affirmed the district court’s decision. Id. ¶¶ 29–30. Baize’s ineffective
    8
    Cite as: 
    2021 UT 9
    Opinion of the Court
    assistance of counsel argument failed because the court of appeals
    concluded that when Baize’s trial counsel argued Baize’s conduct
    was “not a gross deviation from the standard of care,” the “counsel
    effectively communicated the existence of the justification defense
    without making explicit reference to the subsections of the statute.”
    Id. ¶ 29. In other words, the court of appeals concluded that Baize’s
    counsel had, in fact, raised the affirmative defense.
    ¶28 The court of appeals similarly concluded it was “clear” the
    district court analyzed whether Baize’s discipline was the
    “reasonable discipline” a parent can apply without criminal penalty.
    Id. ¶¶ 22–23. The court of appeals pointed to the district court’s
    conclusion that Baize’s “discipline was a gross deviation from the
    standard of care,” which came after the district court recognized that
    “[a] parent should be allowed to discipline his children in an
    appropriate way.” Id. ¶ 22 (emphasis omitted) (quoting the district
    court). The court of appeals reasoned that “gross deviation from the
    standard of care” is “simply a variation in nomenclature describing
    the concept of reasonableness,” and therefore it was unnecessary for
    the district court to “explicitly invoke the numbers” of the relevant
    statutory subsections or explicitly use the words “reasonable” or
    “unreasonable.” Id. ¶¶ 22–23.
    ¶29 The court of appeals further concluded that the district
    court’s analysis was adequate because nothing in the “reasonable
    discipline” statutes requires an examination of the common law
    factors Baize argued the district court had failed to consider. Id.
    ¶¶ 24–25. Finally, the court of appeals rejected Baize’s argument that
    any “parental discipline resulting in mere physical injury,” as
    opposed to serious physical injury, “is by definition reasonable” and
    thus exempted from the crime of child abuse. Id. ¶ 25. The court of
    appeals clarified that, although the reasonable discipline “defense is
    available if the conduct is (1) reasonable and (2) results in only [non-
    serious] physical injury,” id. ¶ 20 n.4, “inflicting something less than
    serious physical injury” is neither “always reasonable” nor always
    unreasonable. Id. ¶ 25.
    ¶30 Baize petitioned for certiorari only on the question of
    “whether the court of appeals erred in its construction and
    application of Sections 76-5-109 and 76-2-401(1)(c) of the Utah Code.”
    Baize did not seek review of the court of appeals’ conclusion that his
    counsel did not render ineffective assistance.
    ISSUE AND STANDARD OF REVIEW
    ¶31 “On certiorari, we review the court of appeals’ decision for
    correctness, focusing on whether that court correctly reviewed the
    9

    Opinion of the Court
    trial court’s decision under the appropriate standard of review.”

    v. Rushton, 
    2017 UT 21
    , ¶ 9, 
    395 P.3d 92
    ). The court of appeals
    reviewed Baize’s statutory interpretation and application arguments
    under a “plain error” standard,8 after finding Baize had not
    preserved the issue at trial. Bountiful City v. Baize, 
    2019 UT App 24
    ,
    ¶ 15, 
    438 P.3d 1041
    .9 “To demonstrate plain error, a defendant must
    establish that ‘(i) [a]n error exists; (ii) the error should have been
    obvious to the trial court; and (iii) the error is harmful. . . .’” State v.

    2017 UT 76
    , ¶ 20, 
    416 P.3d 443
     (alterations in original)
    (citation omitted).
    8If a party “failed to preserve an issue in the trial court, but seeks
    to raise it on appeal . . . . the party must argue an exception to
    preservation.” State v. Johnson, 
    2017 UT 76
    , ¶ 17, 
    416 P.3d 443
    . “Plain
    error” is one of the exceptions that allows an appellate court to
    review an argument that was unpreserved at trial. See 
    id.
     ¶¶ 19–38
    (detailing preservation exceptions).
    9 The court of appeals applied the plain error standard of review
    because Baize’s brief to the court of appeals expressly stated that his
    statutory interpretation and application arguments were “raised for
    the first time on appeal by way of plain error.” Baize then briefed
    why the district court had erred, and why that error was obvious
    and harmful.
    Baize now appears to argue that he preserved his statutory
    interpretation and application arguments by raising them in his
    petition for a writ of certiorari, and/or by his presentation of the
    issue to the court of appeals. But the fact that Baize raised those
    arguments in the court of appeals and in his petition for certiorari
    means that he has not waived his right to petition this court to review
    the court of appeals’ resolution of those issues. It would not cure
    Baize’s initial failure to preserve those issues in the district court. See
    Johnson,

    ANALYSIS
    I. THE STATUTORY FRAMEWORK
    ¶32 It is helpful to review the relevant statutory provisions
    before turning to the parties’ arguments. The general rule under
    Utah Code section 76-5-109 (Child Abuse Statute or Statute) is that
    “[a]ny person who inflicts upon a child physical injury . . . is guilty”
    of a class A, B, or C misdemeanor, depending on the mens rea with
    which the defendant acted. UTAH CODE § 76-5-109(3). It is a class C
    misdemeanor if the offense is “done with criminal negligence.” Id.
    § 76-5-109(3)(c).10
    ¶33 Utah Code section 76-5-109(1)(e) defines “physical injury” as
    “an injury to or condition of a child which impairs the physical
    condition of the child, including: (i) a bruise or other contusion of the
    skin; (ii) a minor laceration or abrasion; (iii) failure to thrive or
    malnutrition; or (iv) any other condition which imperils the child’s
    health or welfare and which is not a serious physical injury. . . .”11
    ¶34 Utah Code section 76-2-103(4) provides that “[a] person
    engages in conduct . . . [w]ith criminal negligence or is criminally
    negligent with respect to circumstances surrounding his conduct or
    the result of his conduct when he ought to be aware of a substantial
    and unjustifiable risk that the circumstances exist or the result will
    occur. The risk must be of a nature and degree that the failure to
    perceive it constitutes a gross deviation from the standard of care
    that an ordinary person would exercise in all the circumstances as
    viewed from the actor’s standpoint.”
    ¶35 After describing the elements of the relevant offense in
    Subsection 3, the Child Abuse Statute then provides specific defenses
    in Subsection 8:
    A person is not guilty of an offense under this section for
    conduct that constitutes: (a) reasonable discipline or
    10  Utah Code subsection 76-5-109(3)(a) makes it a class A
    misdemeanor for “intentionally or knowingly” inflicting physical
    injury, while Utah Code subsection 76-5-109(3)(b) makes it a class B
    misdemeanor for “recklessly” doing so. Baize was charged only with
    a class C misdemeanor.
    11“Serious physical injury” carries its own definition in Utah
    Code subsection 76-5-109(1)(f). No party here argues that “serious
    physical injury” is applicable to Baize’s situation.
    11

    management of a child, including withholding
    privileges; (b) conduct described in Section 76-2-401; or
    (c) the use of reasonable and necessary physical
    restraint or force on a child: (i) in self-defense; (ii) in
    defense of others; (iii) to protect the child; or (iv) to
    remove a weapon in the possession of a child. . . .”
    Id. § 76-5-109(8) (emphases added).12
    ¶36 Utah Code section 76-2-401(1)(c) similarly provides that the
    “defense of justification may be claimed . . . when the actor’s conduct
    is reasonable discipline of minors by parents, guardians, teachers, or
    other persons in loco parentis. . . .” (Emphases added.) This defense
    is “not available if the offense charged involves causing . . . serious
    physical injury. . . .” Id. § 76-2-401(2).
    ¶37 The “reasonable discipline” provisions in sections 76-5-
    109(8) and 76-2-401(1)(c) are affirmative defenses, not elements of the
    offense,13 and thus need only be addressed and negated by the
    prosecution if “the defendant has presented evidence of such
    12 Baize has only raised subsections (a) and (b) of section 76-5-
    109(8).
    13 Utah Code section 76-2-401(1)(c) expressly provides for the
    defense of justification, which may be claimed, meaning that it is not in
    play if unclaimed. And while Utah Code section 76-5-109(8) is not
    expressly listed as a defense, we have held that “exemptions from
    criminal statutes generally function as affirmative defenses.” State v.
    Bess, 
    2019 UT 70
    , ¶¶ 30–31, 
    473 P.3d 157
    . The policy behind this
    general rule is that “the defendant is better positioned to know if any
    of the many possible exemptions even apply in his case,” and
    construing exemptions as elements “would mean that the State
    would have to disprove every exception . . . whether relevant in a
    given case or not.” 
    Id.
     The statutory reasoning is that Utah Code
    section 76-1-501(2) defines “element of the offense” as “(a) the
    conduct, attendant circumstances, or results of conduct proscribed,
    prohibited, or forbidden in the definition of the offense; and (b) the
    culpable mental state required.” See Bess, 
    2019 UT 70
    , ¶ 32. Here,
    “reasonable discipline” is not part of the conduct that is “proscribed,
    prohibited, or forbidden” in section 76-5-109 and thus is not an
    element of the offense. See UTAH CODE § 76-5-109; cf. Bess, 
    2019 UT 70
    , ¶ 32 (coming to the same conclusion on a different statute with a
    similar structure).

    affirmative defense.” See 
    id.
     § 76-1-502(2)(b). But the fact that
    something is an affirmative defense and not an element of the crime
    “does not shift the burden of proof from the State to the defendant.
    Rather, it means that sufficient evidence must be presented at trial to
    put the affirmative defense at issue. At that point, the State must
    disprove the defense beyond a reasonable doubt.” State v. Bess, 
    2019 UT 70
    , ¶ 34, 
    473 P.3d 157
     (citations omitted).
    II. THE COURT OF APPEALS DID NOT ERR IN ITS
    CONSTRUCTION OF THE STATUTE
    ¶38 Baize first asserts that the court of appeals misconstrued the
    Child Abuse Statute. Baize argues that the court of appeals’
    construction “essentially establishes a rule that any spanking by a
    parent that leaves a bruise is guilty of child abuse. . . .” Baize
    contends that this is erroneous in two ways: (A) it runs counter to his
    interpretation of the plain language of the “reasonable discipline”
    provisions in subsections 76-5-109(8) and 76-2-401(1)(c) of the Utah
    Code; and (B) it “unduly abrogate[s]” a “number of factors,” from
    common law and the Restatement (Second) of Torts, which Baize
    asserts must be considered.14
    14 Bountiful City argues that Baize waived his right to have this
    court review the question of whether a district court must consider
    certain common law factors because Baize did not raise arguments
    about some of those factors to the court of appeals, nor did he raise
    those arguments at the district court. Because we reject Baize’s
    contention that the district court must review any set of common law
    factors, we need not sort out whether Baize’s argument about
    additional factors would constitute “entirely new issues” or “entirely
    distinct legal theor[ies]” from the argument Baize made to the court
    of appeals that the district court needed to consider certain other
    common law factors. See State v. Johnson, 
    2017 UT 76
    , ¶ 14 n.2, 
    416 P.3d 443
    . We note, however, that although “we view issues
    narrowly” when examining whether an issue has been preserved or
    waived, we also “routinely consider new authority relevant to issues
    that have properly been” raised below. 
    Id.

    properly raised below, we will review a new argument that is “an
    integral extension of our interpretive task.” Bagley v. Bagley,

    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    ¶39 If Baize’s description of the court of appeals’ opinion were
    accurate, we might be partly inclined to agree with him on the first
    issue. But it is not. Baize mischaracterizes the court of appeals’
    holding. And he asks us for a sweeping interpretation of the
    “reasonable discipline” defense that runs afoul of the Statute’s plain
    language. We therefore reject both of Baize’s statutory interpretation
    arguments.
    A. Baize Misinterprets the Statute and
    Mischaracterizes the Court of Appeals’ Opinion
    ¶40 Contrary to Baize’s characterization, the court of appeals did
    not declare an unbending rule that anytime a parent spanks a child
    and leaves a bruise, that parent is guilty of child abuse. Rather, the
    court of appeals explained that a parent “may be convicted of child
    abuse when he causes physical injury to a child, including bruising,
    unless the conduct in question constituted reasonable discipline.” Bountiful
    City v. Baize, 
    2019 UT App 24
    , ¶ 20, 
    438 P.3d 1041
     (emphasis added)
    (footnote omitted). The court specifically recognized that the
    reasonable discipline “defense is available if the conduct is
    (1) reasonable and (2) results in only [non-serious] physical injury.”
    
    Id.
     ¶ 20 n.4 (emphasis added). The court further clarified that
    “inflicting something less than serious physical injury” is neither
    “always reasonable” nor always unreasonable. Id. ¶ 25. This accords
    with our reading of the Statute.
    ¶41 Not only does Baize mischaracterize the court of appeals’
    opinion, he asks us to adopt his own interpretation of the
    “reasonable discipline” defense. Baize argues that any time a parent
    disciplines a child and causes only non-serious injury, rather than
    serious injury (as those terms are defined in the Statute), such
    discipline should be deemed reasonable and justified or permissible
    under the Statute. Baize made a similar argument at the court of
    appeals, which rejected it.15 We disagree with Baize and agree with
    the court of appeals.
    15 Here, Baize argues that “[t]his defense applies so long as the
    offense did not cause ‘serious bodily injury’ or ‘serious physical
    injury.’” He also argues that “Baize’s conduct did not constitute
    offense” “because the City presented no evidence that the bruise . . .
    was serious or permanent. . . .” Baize’s argument at the court of
    appeals was even more express. There, Baize argued that “discipline
    by a parent—under circumstances such as that in the instant case—is
    reasonable so long as the discipline is administered in a good faith
    (continued . . .)

    Opinion of the Court
    ¶42 “When conducting statutory interpretation, we focus on the
    statute’s plain language because it is the ‘best evidence’ of the
    legislature’s intent.” State v. Flora, 
    2020 UT 2
    , ¶ 21, 
    459 P.3d 975
    (quoting State v. Stewart, 
    2018 UT 24
    , ¶ 12, 
    438 P.3d 515
    ). We
    “presume that the legislature used each word advisedly,” and that
    “the expression of one [term] should be interpreted as the exclusion
    of another,” and we “give effect to every word of a statute, avoiding
    [a]ny interpretation which renders parts or words in a statute
    inoperative or superfluous.” 
    Id.
     (alteration in original) (citations
    omitted) (internal quotation marks omitted). We also “read the plain
    language of the statute as a whole[] and interpret its provisions in
    harmony with other statutes in the same chapter and related
    chapters.” State v. Bess, 
    2019 UT 70
    , ¶ 25, 
    473 P.3d 157
     (alteration in
    original) (quoting State v. Holm, 
    2006 UT 31
    , ¶ 16, 
    137 P.3d 726
    ).
    ¶43 Subsection 8 of Utah Code section 76-5-109 provides that a
    “person is not guilty of an offense under this section for conduct that
    constitutes: (a) reasonable discipline or management of a child . . .; [or]
    (b) conduct described in Section 76-2-401. . . .” (Emphasis added.) In
    turn, Utah Code section 76-2-401 provides that the “defense of
    justification may be claimed . . . when the actor’s conduct is
    reasonable discipline of minors by parents, guardians, teachers, or
    other persons in loco parentis. . . .” UTAH CODE § 76-2-401(1)(c)
    (emphasis added). But, the statute continues, the reasonable
    discipline defense is “not available if the offense charged involves
    causing . . . serious physical injury. . . .” Id. § 76-2-401(2).
    ¶44 Baize’s broad interpretation of the reasonable discipline
    defense appears to stem from section 76-2-401(2). Because this statute
    provides that the defense is “not available if the offense charged
    involves causing . . . serious physical injury,” id. (emphasis added),
    Baize interprets that to mean the “defense applies so long as the
    offense did not cause ‘serious bodily injury’ or ‘serious physical
    manner that does not inflict serious physical injury on the child.” Baize,
    
    2019 UT App 24
    , ¶ 24 (emphasis added). In other words, he argued
    that parental discipline is per se reasonable if it “(1) is done in good
    faith and (2) does not cause serious bodily injury.” 
    Id.
     (emphasis
    added). The court of appeals understood Baize to be arguing that
    “parental discipline resulting in mere physical injury . . . is by
    definition reasonable” and thus exempted from the crime of child
    abuse. Id. ¶ 25. The court of appeals correctly rejected that
    interpretation. See id. ¶¶ 20 n.4, 25.
    15
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    injury.’” In other words, Baize’s reading would allow parents to
    physically injure their children during the course of discipline so
    long as the injury is not “serious,” regardless of the reasonability of
    the parent’s conduct. His reading would also absolve defendants
    from the responsibility of raising affirmative defenses and would
    instead require the prosecution to “disprove every exception . . .
    whether relevant in a given case or not.” Bess, 
    2019 UT 70
    , ¶ 31. That
    is simply not what the Statute envisions.
    ¶45 Baize’s interpretation conflates the term “applies” with the
    term “available,” and renders the term “reasonable” superfluous or
    inoperative. Although we agree that section 76-2-401(2) implies the
    reasonable discipline defense is available to be raised if the discipline
    did not cause serious injury, this does not mean the defense
    automatically applies or exonerates the defendant. Even though a
    defendant need not “establish the justification or excuse by a
    preponderance of the evidence before he is entitled to avail himself
    of that defense,” State v. Dewey, 
    41 Utah 538
    , 
    127 P. 275
    , 280 (1912),
    the existence of the defense does not translate to automatic
    applicability or exoneration. The defendant must still present
    “sufficient evidence . . . to put the affirmative defense at issue.” Bess,
    
    2019 UT 70
    , ¶ 34 (citation omitted).
    ¶46 That means that in the case of the Child Abuse Statute, the
    reasonable discipline defense is put “at issue” if the defendant
    presents sufficient evidence that the discipline was both
    “(1) reasonable and (2) result[ed] in only [non-serious] physical
    injury,” as the court of appeals correctly explained. Baize, 
    2019 UT App 24
    , ¶ 20 n.4. Establishing one of those elements does not
    automatically establish the other, and the court of appeals correctly
    concluded that “inflicting something less than serious physical
    injury” is not “always reasonable,” nor is it always unreasonable. Id.
    ¶ 25. Only after evidence is presented on both the reasonability of
    the discipline and the non-seriousness of the injury does the burden
    shift to the prosecution to disprove either prong of the defense
    beyond a reasonable doubt.16
    16 We clarify that even where a defendant has sufficiently raised
    these two prongs of the reasonable discipline defense, the defendant
    may still be convicted if the prosecution disproves either prong
    beyond a reasonable doubt.

    Opinion of the Court
    ¶47 In sum, we reject Baize’s overbroad reading of the
    reasonable discipline defense and we reject his mischaracterization
    of the court of appeals’ opinion.
    B. Common Law Factors Are Not Required in the Child
    Abuse Statute’s Reasonable Discipline Defense
    ¶48 Baize also argues that the court of appeals erred because it
    failed to read into the Child Abuse Statute a series of common law
    factors he harvests from the Restatement (Second) of Torts. He
    presses us to do what the court of appeals did not; look beyond the
    plain language of the statute to find that “subsection (8) of the
    Statute requires consideration of . . . a number of factors, including
    the nature of the misbehavior, the child’s age and size, and the
    nature and propriety of the force used. . . .”
    ¶49 Baize avers that “the court of appeals unduly abrogated the
    common law factors that are applicable in making a child abuse
    determination” when it failed to take these factors into
    consideration. Baize supports this proposition by reasoning that the
    “common law [is] the rule of decision in Utah courts,” citing Utah
    Code section 68-3-1. Baize misemploys that statute.
    ¶50 While Utah Code section 68-3-1 adopts the “common law of
    England” as the “rule of decision in all courts of this state,” it only
    does so “so far as it is not . . . in conflict with[] the . . . laws of this
    state, and so far only as it is consistent with and adapted to the
    natural and physical conditions of this state and the necessities of the
    people hereof. . . .” Further, Utah Code section 68-3-1 is notably not
    in the Utah Criminal Code, which is housed in title 76. Baize ignores
    Utah Code section 76-1-105, which provides that “[c]ommon law
    crimes are abolished and no conduct is a crime unless made so by
    this code, other applicable statute or ordinance.”
    ¶51 In other words, “Utah’s criminal law is statutory.” State v.
    Miller, 
    2008 UT 61
    , ¶ 16, 
    193 P.3d 92
    . This rule applies not only to the
    elements and mens rea of the crime charged, but also to the defenses
    available. See State v. Gardiner, 
    814 P.2d 568
    , 573–74 (Utah 1991). At
    most, Baize’s citation to Utah Code section 68-3-1 invites us to
    examine whether the legislature’s adoption of his “reasonable
    discipline” defense, as codified in Utah Code sections 76-2-401 and
    76-5-109, leaves room for common law understandings of the
    contours of that defense. But, as we discuss below, none of the cases
    or restatements Baize cites convince us to adopt his theory that the
    statute contemplates a list of factors that the trier of fact must
    consider before it can decide whether a parent’s discipline is
    reasonable or not.
    17
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    ¶52 Indeed, the cases and restatements Baize cites do not
    support his contention that Utah courts must consider a specific list
    of factors when analyzing a “reasonable discipline” defense to a
    criminal charge of child abuse. For example, Baize cites the 1977 U.S.
    Supreme Court case of Ingraham v. Wright, which examined whether
    corporal punishment in Florida schools was permissible under the
    Eighth and Fourteenth Amendments of the U.S. Constitution. 
    430 U.S. 651
    , 653 (1977). This in no way answers the question of when
    and how parental discipline of a child is permissible under Utah’s
    criminal code.
    ¶53 Baize also cites a number of cases reviewing juvenile court
    decisions, which deal with different statutes and different standards
    of proof than those at issue here. See, e.g., State ex rel. L.P., 
    1999 UT App 157
    , ¶ 6, 
    981 P.2d 848
     (overturning the juvenile court for
    applying the definition of child abuse found in the criminal code,
    rather than that in the Juvenile Court Act of 1996). One case Baize
    cites doesn’t even examine the “reasonable discipline” provision17 of
    the Juvenile Court Act. See In re K.T., 
    2017 UT 44
    , ¶¶ 14, 11 n.4, 
    424 P.3d 91
     (holding that it is not “abuse” per se to use an object to strike
    a child absent any evidence of “harm”; but expressly “not
    address[ing] any reasonable discipline exception,” which the parties
    had not raised).
    ¶54 Another juvenile court case Baize cites examines
    “reasonable discipline,” in the context of discipline by a teacher (not a
    parent) charged under the Juvenile Court Act (not the Child Abuse
    Statute). K.Y. v. Div. of Child & Family Servs., 
    2010 UT App 335
    , 
    244 P.3d 399
    . But the issue there arose in the layered context of a
    provision of the public education code protecting teachers in a way
    that differs from the reasonable discipline provision of Utah Code
    section 76-5-109(8). Compare UTAH CODE § 76-5-109(8), with K.Y., 
    2010 UT App 335
    , ¶ 23 (discussing UTAH CODE § 53A-11-804 (renumbered
    as § 53G-8-304)). Even if K.Y. were applicable to Baize’s situation, it
    17 Multiple cases the City cites also fail to address the “reasonable
    discipline” provision under the Child Abuse Statute. See West Valley
    City v. Norris, 2001 UT App 279U, para. 1, 
    2001 WL 1135405
    ; Provo
    City v. Cannon, 
    1999 UT App 344
    , ¶ 2, 
    994 P.2d 206
    . Nor do they
    address “reasonable discipline” under the Juvenile Court Act. See
    K.A.M. v. State, Div. of Child & Family Servs., 2004 UT App 48U, 
    2004 WL 396421
    ; In re K.C., 
    2013 UT App 201
    , ¶ 18,

    do not find those cases helpful to our analysis either.

    Opinion of the Court
    would only establish the unremarkable proposition that “the record
    must support a conclusion that [defendant’s] actions fall within the
    statutory abuse definition. . . .” K.Y., 
    2010 UT App 335
    , ¶ 23.
    ¶55 K.Y. does hold that when a court makes a reasonable
    discipline determination, then “[t]he issue of whether discipline was
    reasonable is a fact-dependent analysis that must take into account
    the various circumstances of the particular case.” Id. ¶ 25.18 True
    enough. But that holding does not support Baize’s theory that courts
    must examine a specific list of factors in making reasonable
    discipline determinations. It simply establishes that the trier of fact
    must make a case-specific, circumstance-specific factual inquiry.
    ¶56 Baize’s citations to In re L.P., 
    1999 UT App 157
    , 
    981 P.2d 848
    ,
    likewise do not prove his argument that the Child Abuse Statute
    requires a court to work from a specific list of common law factors to
    decide whether a parent reasonably disciplined their child. The court
    of appeals in In re L.P. advised that juvenile courts—in the process of
    determining whether the definition of “abused child” has been met
    under the Juvenile Court Act19—should make “detailed findings
    supporting [their] ultimate decision” and “[s]uch factual findings
    may include, but are not limited to” a long list of factors, one of which
    was “reasonable discipline.” Id. ¶ 8 (emphases added).
    ¶57 Thus, In re L.P. does not support Baize’s proposition for at
    least three reasons. First, In re L.P. did not list factors to be used in a
    reasonable discipline determination, but rather, it listed “reasonable
    discipline” as one factor for making an “abused child” determination.
    Id. (emphasis added). Second, the L.P. court expressly did not
    18  Although K.Y. supports this proposition by citing to In re L.P.,
    
    1999 UT App 157
    , ¶¶ 8–9, 
    981 P.2d 848
    , explaining that In re L.P.
    “list[s] various factors that may indicate whether discipline was
    reasonable,” K.Y., UT App 335, ¶ 23, that does not indicate the K.Y.
    court thought such factors must be expressly considered as a matter
    of course in every case. Moreover, as we explain in the following
    paragraph, K.Y. mischaracterized In re L.P., because L.P. in fact did
    not list factors for a reasonable discipline determination but rather
    listed possible factors for an abuse determination.
    19 The Juvenile Court Act of 1996 defines “abused child” as when
    a child has suffered “nonaccidental harm.” See In re L.P., 
    1999 UT App 157
    , ¶ 7 (citing UTAH CODE § 78-3a-103(1)(a)(i) (renumbered as
    § 78A-6-105)).

    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    provide guidance for criminal statutes such as Utah Code section 76-
    5-109. See id. ¶ 6. Third, In re L.P. said the factors “may include,” not
    must include, and it expressly said that “[n]one of the factors listed
    above is necessarily dispositive,” and the factors should simply
    “guide the juvenile court as it exercises its broad discretion in making
    that determination.” Id. ¶ 8 (emphases added); see also In re K.T., 
    2017 UT 44
    , ¶ 12 (reiterating that In re L.P. simply “listed a number of
    factors that a juvenile court should consider before determining
    whether a child has been abused within the meaning of the [Juvenile
    Court Act]” and that “[n]one of the factors . . . is necessarily
    dispositive.” (second alteration in original)).
    ¶58 In sum, Baize has cited nothing that controls our statutory
    analysis under the Child Abuse Statute. Nor has he cited any
    authority that supports his contention that Utah courts must consider
    certain factors in making a reasonable discipline determination. We
    nevertheless extract some useful guidance from some of those cases.
    First, we agree with K.T. that a trier of fact should “examine
    situations as a whole,” and that no one factor is necessary or
    sufficient for such a determination. See In re K.T., 
    2017 UT 44
    , ¶¶ 16,
    12. That logic applies with equal force to reasonable discipline
    determinations under the Child Abuse Statute.
    ¶59 In addition, we agree with K.Y. that “[t]he issue of whether
    discipline was reasonable is a fact-dependent analysis that must take
    into account the various circumstances of the particular case.” See
    K.Y., 
    2010 UT App 335
    , ¶ 25. This accords with the ordinary meaning
    of “reasonable.” See Reasonable, BLACK’S LAW DICTIONARY (11th ed.
    2019) (“Fair, proper, or moderate under the circumstances. . . .”); see
    also STEPHEN MICHAEL SHEPPARD, Reasonable (Reasonableness), in THE
    WOLTERS KLUWER BOUVIER LAW DICTIONARY (Desk ed. 2012) (“A
    reasonable action is what most rational and fair-minded people
    could be expected to do in a given situation. Reasonableness differs
    from but is related to the idea of the right thing to do, or the moral
    duty to do what is right.”).
    ¶60 We also borrow from In re L.P. to note that that “the
    relationship between the need and the amount [and type] of
    punishment administered,” 
    1999 UT App 157
    , ¶ 8 (citation omitted),
    may be relevant to a court’s determination of whether parental
    discipline was reasonable. Likewise, the child’s age and size may
    also be relevant in some situations. But we reiterate that these factors
    may not necessarily be relevant in every case. As the court of appeals
    noted, district courts have “broad discretion” to determine the
    factors that are relevant in a particular case.

    Opinion of the Court
    ¶61 Finally, and important to the discussion we undertake in the
    next section, we also agree with something else the court of appeals
    stated in In re L.P. There, the court of appeals observed that trial
    courts should make “detailed findings supporting [their] ultimate
    decision so that a body of case law can be developed,” and so
    appellate courts can “review abuse determinations more effectively.”
    
    Id.
     ¶¶ 8–9.
    ¶62 Simply stated, the court of appeals did not err when it
    rejected Baize’s argument that the district court needed to examine a
    specific list of common law factors to decide whether Baize’s
    discipline was reasonable. Baize, 
    2019 UT App 24
    , ¶¶ 24–25.
    III. THE COURT OF APPEALS ERRED IN
    CONCLUDING THAT THE DISTRICT COURT
    CORRECTLY APPLIED THE STATUTE
    ¶63 Baize next argues that the court of appeals erred in its
    application of the Child Abuse Statute. The district court, Baize
    argues, failed to engage in a “reasonable discipline” analysis
    separate from its examination of the Statute’s mens rea requirement.
    According to Baize, the court of appeals mistook the district court’s
    examination of the mens rea (criminal negligence) for a “reasonable
    discipline” analysis and therefore erroneously concluded that the
    district court sufficiently applied the two necessary tests. Baize
    alternatively argues that, if the district court did analyze the
    reasonable discipline defense, it did so incorrectly. We agree with
    Baize in part.
    A. Neither Party Has Petitioned for Review of the Court of
    Appeals’ Determination that Baize’s Trial Counsel
    Raised the Reasonable Discipline Defense
    ¶64 Before turning to the court of appeals’ determination that
    the district court actually and sufficiently undertook a “reasonable
    discipline” analysis, we first explain why we will operate from the
    assumption that the prosecution and district court had an obligation
    to address the defense.
    ¶65 We reiterate that the “reasonable discipline” provisions in
    sections 76-5-109(8) and 76-2-401(1)(c) of the Utah Code are
    affirmative defenses, not elements of the offense, and thus need only
    be addressed and negated by the prosecution if “the defendant has
    presented evidence of such affirmative defense.” See UTAH CODE
    § 76-1-502(2)(b); see also supra ¶¶ 37, 46. The prosecution must
    disprove the defense beyond a reasonable doubt only after “sufficient
    evidence [has been] presented at trial to put the affirmative defense
    21
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    at issue.” State v. Bess, 
    2019 UT 70
    , ¶ 34, 
    473 P.3d 157
     (citation
    omitted); see also State v. Drej, 
    2010 UT 35
    , ¶ 15, 
    233 P.3d 476
     (“The
    Utah rule requires that the prosecution ‘disprove the existence of
    affirmative defenses beyond a reasonable doubt once the defendant has
    produced some evidence of the defense.’” (emphasis added) (citation
    omitted)). This assumes importance here because it was incumbent
    upon Baize to raise the affirmative defense at trial in order to trigger
    the prosecution’s and district court’s obligation to address that
    defense.
    ¶66 In the court of appeals, Baize argued that he had been
    denied effective assistance of counsel because his trial attorney did
    not raise the defense.20 Before us, the City pounces on Baize’s
    argument before the court of appeals that his counsel rendered
    ineffective assistance of counsel. And the City argues that “it is
    undisputed Baize did not raise [the] defense during the trial.” Based
    on this, the City posits that we need not address Baize’s argument
    that the district court misapplied the defense.
    ¶67 But the City’s contentions on this point ignore the court of
    appeals’ conclusion that Baize’s trial counsel sufficiently raised and
    “effectively communicated the existence of the [reasonable
    discipline] justification defense. . . .” Bountiful City v. Baize, 
    2019 UT App 24
    , ¶ 29, 
    438 P.3d 1041
    . The court of appeals’ conclusion echoes
    through our opinion because if Baize’s counsel raised the defense,
    then the prosecution had an obligation to respond to and disprove
    the defense, and the district court had an obligation to address it and
    make findings. See supra ¶¶ 37, 46.
    ¶68 Baize’s petition for certiorari does not ask us to review this
    part of the court of appeals’ decision, nor has the City cross-
    petitioned us to review it. Instead, Baize implies, and the City
    effectively concedes, that Baize’s counsel raised the defense and,
    therefore, the district court needed to engage in such an analysis.
    Baize argued to us that “these affirmative defenses were squarely
    before the court by virtue of its ‘reasonable discipline analysis’” and
    therefore “the City bore the burden of disproving at least one
    20  In his briefing to the court of appeals, Baize conceded that his
    trial counsel’s “arguments at closing. . . . were essentially consistent
    with the defense of justification.” Bountiful City v. Baize, 
    2017 UT App 25
    , ¶ 28, 
    438 P.3d 1041
    . This permitted the court of appeals to reject
    the ineffective assistance of counsel argument.
    22
    Cite as: 
    2021 UT 9
    Opinion of the Court
    element of these defenses. . . .” And, by implication, Baize assumes
    the district court would then also need to address those defenses.
    ¶69 The City, on the other hand, initially rebuts Baize’s
    assertions by contending “Baize never raised these defenses during
    trial” and, therefore, the City did not “bear[] the burden of
    disproving the elements of the defenses. . . .” But the City goes on to
    concede that “the record contains testimony and colloquy by the City
    and Baize’s counsel regarding both the ‘justification’ and ‘reasonable
    discipline defense.’” (Emphasis added.) The City further contends,
    “[b]oth the trial and appellate courts had access to testimony about
    the victim’s poor behavior. . . . In fact the Court of Appeals cited
    exculpatory facts regarding both ‘reasonable discipline’ and
    justification in its opinion.” This causes the City to argue that “the
    Court of Appeals had a ‘complete picture’ when it rendered its
    analysis and this issue is moot.” (Emphasis added.) In other words,
    the City argues that Baize’s trial counsel, the City’s trial counsel, and
    the district court all addressed the issues of “reasonable discipline”
    and “justification,” so the question of whether Baize’s counsel put
    the reasonable discipline defense at play is irrelevant or moot. The
    parties’ disagreement before us, therefore, hinges on whether the
    district court actually and/or correctly undertook a reasonable
    discipline analysis.
    ¶70 The adversarial nature of our judicial system is based “on
    the premise that parties are in the best position to select and argue
    the issues most advantageous to themselves. . . .” State v. Johnson,
    
    2017 UT 76
    , ¶ 8, 
    416 P.3d 443
    . “[P]arties have the duty to identify
    [the] legal issues and bring [the] arguments” they are pursuing. Id.
    ¶ 14. “If the parties fail to raise an issue in either the trial or appellate
    court, they risk losing the opportunity to have the court address that
    issue.” Id. (footnote omitted).
    ¶71 In light of this posture, we proceed from the presumption
    that the district court needed to conduct a reasonable discipline
    analysis because: (1) the court of appeals determined that Baize’s
    trial counsel effectively raised the “reasonable discipline” affirmative
    defense; (2) neither of the parties challenged the court of appeals’
    holding in that respect; (3) neither party directly argues that the
    district court did not need to perform a reasonable discipline
    analysis; and (4) the City’s assertion that Baize’s trial counsel
    engaged in a “colloquy” and “testimony” “regarding both
    ‘justification’ and ‘reasonable discipline’” effectively constitutes a
    concession that Baize’s trial counsel did raise the defense. We
    therefore refrain from revisiting whether Baize preserved the
    23
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    defense and whether the court of appeals’ determination binds us to
    the conclusion that Baize raised the defense in the district court.
    ¶72 In other words, because of the way the parties have
    approached this case, the question before us is not whether the
    district court needed to perform a “reasonable discipline” analysis,
    but rather whether the court of appeals was correct in holding that
    the district court’s reasoning amounted to a “reasonable discipline”
    analysis at all.
    B. The Court of Appeals Erred in Concluding That the
    District Court Clearly Applied the Statute Correctly
    ¶73 We disagree with the court of appeals’ conclusion that it is
    “clear from the record” that the district court actually and correctly
    conducted a “reasonable discipline” analysis. See Baize, 
    2019 UT App 24
    , ¶¶ 22–23. We find the record far less clear than the court of
    appeals did.
    ¶74 The court of appeals based its conclusion on this portion of
    the district court’s analysis:
    [A] parent should be allowed to discipline his children
    in an appropriate way. But the level of contusion, the
    bruising on the buttocks of the child causes me to come
    to the conclusion that [the] discipline was a gross
    deviation from the standard of care that an ordinary person
    would exercise. It was just too hard.
    See id. ¶ 22 (quoting the district court) (emphases added by the court
    of appeals). The court of appeals reasoned that “gross deviation from
    the standard of care” is “simply a variation in nomenclature
    describing the concept of reasonableness. If anything, the court’s
    finding is more specific than simply saying the word
    ‘unreasonable.’” Id. ¶ 23. We are far less certain than the court of
    appeals that the district court had the reasonable discipline defense
    in mind when it engaged in that analysis.
    ¶75 The court of appeals appears to have discounted that “gross
    deviation from the standard of care” is specifically the language of
    the relevant mens rea—criminal negligence—which appears in
    section 76-2-103(4) of the Utah Code. The district court read this
    statute aloud earlier in the proceeding, “to make sure we are all on
    the same page.” Further, the district court expressly emphasized its
    focus on the mens rea when it interrupted the closing argument of
    the City, who had begun to say that, in this case, “the focus of course
    should be. . . .” The court interjected: “The mens rea.” In contrast, the
    district court did not read from or cite any defense or justification in
    24
    Cite as: 
    2021 UT 9
    Opinion of the Court
    section 76-5-109(8) or 76-2-401 of the Utah Code. Nor did it use the
    term “reasonable discipline” in its deliberations.
    ¶76 There may be some merit to the court of appeals’
    observation that the district court acknowledged that “a parent
    should be allowed to discipline his children in an appropriate way,”
    and “the fact that Baize was [Son’s] parent . . . is relevant under Utah
    Code section 76-5-109(8).” Baize, 
    2019 UT App 24
    , ¶ 22 (emphasis
    omitted).21 It may also be consequential that the district court was
    concerned not just with any amount of contusion or bruising, but
    specifically “the level of contusion, the bruising,” and that it “was just
    too hard.” 
    Id.
     (emphasis added).
    ¶77 But when we look beyond the snippets of the district court’s
    decision that the court of appeals discussed and examine them in the
    context of the whole record, we have serious doubts that the district
    court was undertaking an analysis of whether Baize’s conduct
    constituted permissible “reasonable discipline.” Instead, it appears
    that the district court was focused on whether Baize’s behavior met
    the criminal negligence standard of mens rea. And while we
    recognize the possibility that a reasonable discipline determination
    may be supported by the same facts as a criminal negligence
    determination, we cannot allow one conclusion to wholly and
    implicitly serve double-duty for the other. The Statute includes two
    separate provisions for criminal negligence as the mens rea of the
    crime and for reasonable discipline as an affirmative defense.
    Because it’s unclear from the record whether the district court’s
    analysis was anything other than an analysis of criminal negligence,
    and because a district court’s criminal negligence finding cannot
    implicitly serve as a “reasonable discipline” finding, we cannot let
    the court of appeals’ decision stand.
    ¶78 Even if the district court did have the reasonable discipline
    defense in mind, the record indicates that the district court may have
    considered certain relevant circumstances to be irrelevant. As this
    case will return to the district court on remand, we take the occasion
    to clarify this potential misapplication of the Statute. Specifically, we
    are troubled that the district court said, “I think [the City] has it
    right,” after the City had repeatedly argued for application of
    21 We clarify that Utah Code section 76-5-109(8) applies to any
    “person,” but section 76-2-401(1)(c), which is incorporated by
    reference in 76-5-109(8), applies to “parents, guardians, teachers, or
    other persons in loco parentis. . . .”
    25
    BOUNTIFUL CITY v. BAIZE
    Opinion of the Court
    something akin to a per se rule and encouraged the district court to
    disregard potentially relevant considerations that could have spoken
    to the reasonableness of Baize’s discipline. Specifically, the City
    repeatedly argued that Son’s “behavior really doesn’t matter in the
    scheme of things.” The City further asserted that “[i]t comes down to
    the fact that while disciplining his child [Baize] left a handprint on
    [Son], bruised him. . . . That’s it.” Baize, 
    2019 UT App 24
    , ¶ 11 (third
    alteration in original).
    ¶79 As we have already discussed, that’s not it. When the
    defendant has presented sufficient evidence to put the affirmative
    defense of “reasonable discipline” at issue, then the prosecution
    must also disprove that defense beyond a reasonable doubt. See
    supra ¶ 37. Further, although the Statute does not require an
    examination of the specific common law factors that Baize argues a
    district court must consider, the Statute does require an examination
    of all relevant circumstances, as we discussed above. See supra
    ¶¶ 58–62. And, moreover, a court is obligated to enter findings
    sufficient to allow a reviewing court to examine the thinking behind
    its determination that the discipline was reasonable or not. We do
    not have that type of record before us.
    ¶80 Because of the district court’s comments appearing to
    approve of the City’s incorrect interpretation of the Statute’s
    requirements, we are unsure whether the court correctly analyzed
    the reasonable discipline defense. In other words, to the extent the
    district court considered whether Baize’s discipline was reasonable,
    we have no visibility into what facts the district court might have
    considered to make that determination. Without that detail, we
    cannot meaningfully review the district court’s decision. Thus, we
    order remand to permit the district court to clarify its ruling.
    CONCLUSION
    ¶81 Although we hold that the court of appeals was largely
    correct in its construction of the Child Abuse Statute, we
    nevertheless hold that the court erred when it concluded that it was
    “clear” the district court correctly applied the Statute’s “reasonable
    discipline” defense. On the findings in front of us, we are unable to
    ascertain whether the district court addressed the defense and, if it
    did, what was the basis for a determination that Baize’s discipline
    was not reasonable. We therefore vacate Baize’s conviction and
    remand to the district court to squarely address Baize’s reasonable
    discipline defense. The district court may, if it deems helpful, permit
    further evidence and argument on that question, and conduct any
    other proceedings necessary to address the “reasonable discipline”
