    IN RE SEX CHANGE
    Opinion of the Court
    JUSTICE HIMONAS, opinion of the Court:
    INTRODUCTION
    ¶1 Appellants, Sean Childers-Gray and Angie Rice,
    petitioned the district court to change their legal sex designations
    because the designations do not reflect their identities. Supposing
    such matters implicate a purely legislative prerogative, the district
    court denied Appellants‘ petitions.
    ¶2 The district court was mistaken in its supposition. A
    person has a common-law right to change facets of their personal
    legal status, including their sex designation. In recognition of this
    right, the Utah legislature has statutorily declared that, as a matter
    of the public policy of this state, when ―a person born in this state
    has a name change or sex change approved by an order of a Utah
    district court,‖2 they can file such order with the state registrar
    with an application to change their birth certificate. UTAH CODE
    § 26-2-11(1).3 If the registrar determines the application is
    complete, the registrar must change the sex on the person‘s birth
    certificate. Id.
    ¶3 Associate Chief Justice Lee‘s dissent disagrees on all
    fronts, contesting the relevant legislation and the historical
    practice of Utah courts. The dissent suggests that it is protecting
    the interests of the State. See, e.g., infra ¶ 195 (suggesting that our
    articulated standard ―will control all future proceedings in our
    Utah courts and will bind the executive branch of our government
    . . . going forward‖). Yet the State does not argue for the principles
    __________________________________________________________
    2  To be more exact, the relevant statutory provision also
    extends to orders of ―a court of competent jurisdiction of another
    state or a province of Canada.‖ UTAH CODE § 26-2-11(1).
    3 Utah Code section 26-2-11 was originally enacted in 1975. See
    
    1975 Utah Laws 222
    ; (originally codified at UTAH CODE
    § 26-15-16.5 (1975)). In 1981, the legislature re-codified the entire
    chapter and re-numbered it, resulting in the current citation—
    section 26-2-11. 
    1981 Utah Laws 598
    . Aside from the renumbering,
    no material change was made to this section. A change was only
    made in 1995, which included minor linguistic changes. See 
    1995 Utah Laws 676
    . Neither the parties nor the concurrence or dissents
    claim any such changes matter. In this opinion, we refer to the
    section in its current numbering and language unless we explicitly
    say otherwise.

    Opinion of the Court
    the dissent advances. In its amicus brief, the State either opposes
    the dissent‘s position or presents arguments for why we should
    not reach such a resolution. Nevertheless, we take care
    throughout our opinion to respond to the dissent‘s arguments,
    which we firmly reject.
    ¶4 Today, we provide a plain-meaning interpretation of the
    duly enacted law allowing individuals to change their sex
    designations. In the process, we explain that Mr. Childers-Gray
    and Ms. Rice met the requirements—articulated by us today but
    rooted in common law and applied by Utah district courts and
    other authorities—for their sex-change petitions to be approved.4
    Accordingly, we reverse and remand with instructions to enter
    orders granting their sex-change petitions.5
    __________________________________________________________
    4  Language matters: We address appellants by their
    appropriate pronouns. The ease with which we could have
    misgendered them by using opposite-sex pronouns, despite their
    appearances and pronouncements, amplifies the importance of
    matching their government identification documents to their
    held-out identities.
    5  Again, language matters: Appellants and the district court
    use several different terms to describe the change to legal status or
    identification requested in the petition. For the convenience of the
    reader, and without definitively rejecting other terms, we use in
    this opinion the terms ―sex change‖ and ―sex designation
    change,‖ rather than ―gender change.‖ We also note that the
    legislature has indicated in another context that in Utah, ―‗sex‘
    means gender.‖ UTAH CODE § 57-21-2(22). We recognize that these
    terms do ―have distinct meanings. ‗Gender‘ generally refers to a
    social construct based on psychological characteristics that classify
    an individual as feminine or masculine, while ‗sex‘ generally
    refers to biological sex as evidenced by chromosomes, genitals,
    and other physical characteristics.‖ Gram v. Intelligender, LLC, CV
    10-4210 ABC (VBKx) 
    2010 WL 11601035
    , at *1 n.2 (C.D. Cal. Oct. 8,
    2010). In this context, we find it noteworthy that while the
    legislature said that ―‗sex‘ means gender,‖ it did not say the
    opposite, i.e., that gender means sex. Therefore, we assume that by
    choosing this equation, the legislature, in its wisdom, conferred
    broader meaning to the term ―sex.‖

    IN RE SEX CHANGE
    Opinion of the Court
    BACKGROUND
    ¶5 Sean Childers-Gray6 is a transgender7 man who was
    assigned female at birth. He ―lives 100% as a male‖ and holds
    himself out as a male to his family, friends, and the public. He
    was diagnosed with gender identity disorder8 and underwent
    hormone therapy to change his physical appearance. At the time
    of his petition, he had been treated with hormone therapy for
    more than three years. This therapy significantly changed his
    voice, body hair growth, and breast tissue, and caused his female
    organs to no longer function.
    __________________________________________________________
    6 Mr. Childers-Gray has changed his birth name to reflect his
    identity.
    7  The American Psychological Association defines transgender
    as ―an umbrella term for persons whose gender identity, gender
    expression or behavior does not conform to that typically
    associated with the sex to which they were assigned at birth.‖

    (―A person whose physical sex at birth differs from the sex with
    which the person later identifies.‖).
    8 Appellants do not define ―gender identity disorder,‖ but an
    American Medical Association resolution defines it as ―a
    persistent discomfort with one‘s assigned sex and with one‘s
    primary and secondary sex characteristics, which causes intense
    emotional pain and suffering . . . .‖ AM. MED. ASS‘N, RESOLUTION
    122            (A-08)             at          1              (2008),

    , 1136–37 (D. Idaho 2018) (citing the
    American Medical Association‘s definition of gender identity
    disorder). Although Mr. Childers-Gray uses the term ―gender
    identity disorder‖ to describe his diagnosis, we use the term
    ―gender dysphoria‖ for the reasons we set forth in ¶ 6 n.10.

    Opinion of the Court
    ¶6 Angie Rice9 is a transgender woman who was assigned
    male at birth. She ―lives 100% as a female‖ and holds herself out
    as a female to her family, friends, and the public. She was
    diagnosed with gender dysphoria,10 and at the time of her
    petition‘s filing, she had been treated with hormone therapy for
    five years to change her physical appearance.
    ¶7 Mr. Childers-Gray and Ms. Rice each filed petitions in the
    district court, seeking orders to change their names and sex,
    which would allow them to change the designations on their birth
    certificates. The petitions complied with the requirements
    __________________________________________________________
    9 Ms. Rice has also changed her birth name to reflect her
    identity.
    10  Appellants do not define ―gender dysphoria‖ either.
    However, another court has explained that it is a ―clinical medical
    condition‖ that ―can result from‖ the emotional stress produced
    from a gender identity disorder. F.V., 286 F. Supp. 3d at 1136–37.
    That court also adopted the definition of the American Psychiatric
    Association for gender dysphoria, which further explains that
    ―[p]eople with gender dysphoria may often experience significant
    distress and/or problems functioning associated with this conflict
    between the way they feel and think of themselves (referred to as
    experienced or expressed gender) and their physical or assigned
    gender.‖ Id. at 1137 n.7 (quoting What is Gender Dysphoria?, AM.
    PSYCHIATRIC ASS‘N (Jack Turban, Physician Reviewer, Nov. 2020),
    https://www.psychiatry.org/patients-families/gender-
    dysphoria/what-is-gender-dysphoria).
    The American Psychiatric Association found that the term
    ―disorder‖ suggests a ―stigma‖ that can get in the way of
    ―ensur[ing] clinical care‖ for those who might otherwise seek it.
    See AM. PSYCHIATRIC ASS‘N, GENDER DYSPHORIA (2013),
    https://www.psychiatry.org/File%20Library/Psychiatrists/Pract
    ice/DSM/APA_DSM-5-Gender-Dysphoria.pdf (noting that DSM-
    5 ―replace[d] the diagnostic name ‗gender identity disorder‘ with
    ‗gender dysphoria‘‖ to ―avoid stigma and ensure clinical care for
    individuals who see and feel themselves to be a different gender
    than their assigned gender‖). We therefore use the term ―gender
    dysphoria‖ throughout this opinion. We note that other courts
    have recently done the same. See, e.g., Hecox v. Little, 
    479 F. Supp. 3d 930
    , 945 (D. Idaho 2020), appeal docketed, No. 20-35813 (9th Cir.
    Sept. 17, 2020).
    5
    IN RE SEX CHANGE
    Opinion of the Court
    outlined in Utah Code section 42-1-1, which governs name-change
    petitions (Utah does not have a statute governing the express
    content of sex-change petitions). Specifically, the petitions
    included the reasons for the name and sex changes and statements
    that Mr. Childers-Gray and Ms. Rice had been residents of the
    county where they lived for at least one year before filing. See
    UTAH CODE § 42-1-1. In addition, both petitions included letters
    from a medical doctor stating that appellants had been treated for
    gender dysphoria and had undergone ―the appropriate clinical
    treatment‖ for gender transition. The petitions also stated that
    appellants were not listed on the sex offender registry, involved in
    any legal proceedings, placed on probation or parole, seeking to
    avoid creditors, or seeking the name- and sex-designation changes
    for any fraudulent purpose. Ms. Rice‘s petition also documented
    her personal history, the significant emotional distress that she
    endured in the past when presenting herself as a man, and the
    negative treatment she endures now because her ―documentation
    doesn‘t match who‖ she is.
    ¶8 The district court granted Mr. Childers-Gray‘s and Ms.
    Rice‘s name-change petitions, ruling that all statutory
    requirements had been satisfied. But the district court denied their
    sex-change petitions.
    ¶9 The district court gave two reasons for denying Mr.
    Childers-Gray‘s sex-change petition. First, it held ―there is no
    statute in the State of Utah that sets forth either standards or
    procedures under which the court may consider such request.‖
    The district court found that such lack of legislative guidance
    meant that a sex-change matter is a nonjusticiable political
    question. Second, the district court denied the sex-change petition
    under the name-change standard. It explained that a name-change
    petition must be denied if it will ―affect the legal rights or duties
    of either the petitioner or anyone else.‖ Applying that standard to
    sex-change petitions, the district court found that granting the
    sex-change petition was undoubtedly bound to affect others‘
    rights. It then gave numerous hypotheticals in which a sex change
    would affect the ―rights and duties of others that interact with‖
    Mr. Childers-Gray.
    ¶10 The district court did not rely on this second reason
    when it denied Ms. Rice‘s sex-change petition. It held only that
    ―[t]he procedure for obtaining a sex/gender marker change must
    be set forth by the legislature,‖ and because it was not, the district
    6
    Cite as: 
    2021 UT 13
    Opinion of the Court
    court found itself ―prohibited from invading the legislature‘s
    prerogative on this issue.‖
    ¶11 Appellants appealed the orders denying their petitions
    for sex changes. We consolidated the cases.11
    ¶12 During oral argument in January 2018, we noted sua
    sponte that appellants come before us unopposed and questioned
    whether this lack of adversariness deprived us of jurisdiction to
    hear the case. In November 2018, we issued an order staying this
    case pending our decision in In re Gestational Agreement, a case
    that also lacked adversariness and in which we expected to
    address the impact of such posture on our jurisdiction. We issued
    an opinion in that case in August 2019, In re Gestational Agreement,
    
    2019 UT 40
    , 
    449 P.3d 69
    , and consequently requested
    supplemental briefing from appellants and called for the views of
    the State, through the Attorney General, under rule 25A(c) of the
    Rules of Appellate Procedure. We have jurisdiction under Utah
    Code section 78A-3-102(3)(j).
    STANDARD OF REVIEW
    ¶13 Although we have never reviewed a district court‘s
    decision to grant or deny a petition for sex change, we have
    reviewed decisions on petitions for name change ―under an abuse
    of discretion standard.‖ In re Porter, 
    2001 UT 70
    , ¶ 4, 
    31 P.3d 519
    .
    Because name changes and sex changes are analogous, see infra
    ¶¶ 40–43, we also review for abuse of discretion a district court‘s
    decision to grant or deny a petition for a sex change. And we
    review the legal questions underlying the determination for
    correctness. See Taylor v. Univ. of Utah, 
    2020 UT 21
    , ¶ 13, 
    466 P.3d 124
    .
    ¶14 ―We review questions of statutory interpretation for
    correctness, affording no deference to the district court‘s legal
    conclusions.‖ State v. Outzen, 
    2017 UT 30
    , ¶ 5, 
    408 P.3d 334
    (citation omitted). And we review ―the constitutionality of a
    statute for correctness, giving no deference to the lower court‘s
    interpretation,‖ State v. Greenwood, 
    2012 UT 48
    , ¶ 26, 
    297 P.3d 556
    ,
    presuming ―the statute is constitutional‖ and resolving ―any
    reasonable doubts in favor of constitutionality.‖ Brown v. Cox,

    Opinion of the Court
    
    2017 UT 3
    , ¶ 11, 
    387 P.3d 1040
     (quoting State v. Drej, 
    2010 UT 35
    ,
    ¶ 9, 
    233 P.3d 476
    )).
    ANALYSIS
    ¶15 We begin with jurisdiction. Sex-change petitions
    quintessentially ask for a change in a person‘s legal status or
    identification. We have ―judicial power‖ to adjudicate sex-change
    petitions because they seek changes to a petitioner‘s legal status or
    identification, and such ―function[] w[as] intended by the framers
    of our constitution to be included in the constitutional grant to the
    judiciary.‖ In re Gestational Agreement, 
    2019 UT 40
    , ¶ 13, 
    449 P.3d 69
    . And so, we have jurisdiction to adjudicate them.
    ¶16 With jurisdiction to hear sex-change petitions, we move
    to the question of a district court‘s authority to adjudicate them,
    i.e., whether there is a framework for adjudicating such petitions.
    Utah district courts have common-law authority, as codified by
    statute, to adjudicate petitions for a name change. In re Porter,
    
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
    . Utah law presupposes a district
    court‘s authority to order name and sex changes, see UTAH CODE
    § 26-2-11(1) (referring to ―[w]hen a person born in this state has a
    name change or sex change approved by an order of a Utah
    district court‖), thereby conferring on sex-change adjudication the
    common-law authority existing with respect to name-change
    adjudication. See Maxfield v. Herbert, 
    2012 UT 44
    , ¶ 31, 
    284 P.3d 647
    (―[W]hen a word or phrase is transplanted from another legal
    source, whether the common law or other legislation, it brings the
    old soil with it.‖ (internal quotation marks omitted)). Any lack in
    a statute to detail the content of a sex-change petition has no effect
    on a district court‘s authority to adjudicate and approve such a
    petition because the district court‘s authority is based on common
    law and independent from statute. As such, we find ample
    authority in the district court to adjudicate sex-change petitions.
    ¶17 We then examine whether there are any constitutional
    barriers to our adjudication of sex-change petitions. We hold that
    neither Utah Code section 26-2-11 nor the adjudication of sex-
    change petitions run afoul of the Utah constitution or separation-
    of-powers principles.
    ¶18 Finding jurisdiction, authority, and no constitutional
    impediment to adjudicating sex-change petitions, we next
    articulate and explain the test to decide sex-change petitions. In
    doing so, we refute the test identified by the dissent. Our test has
    already been used by our district courts, exercising their common-
    law judgment. The test we articulate borrows from our common-
    8
    Cite as: 
    2021 UT 13
    Opinion of the Court
    law jurisprudence about name-change petitions and is adapted to
    fit sex-change petitions. We conclude that, as a general rule, sex-
    change petitions should be granted if (1) they are not ―sought for
    a wrongful or fraudulent purpose,‖ In re Porter, 
    2001 UT 70
    , ¶ 8
    (quoting Isom v. Cir. Ct. of the Tenth Jud. Cir., 
    437 So.2d 732
    , 733
    (Fla. Dist. Ct. App. 1983)), and (2) they are supported by objective
    evidence of a sex change, which includes, at minimum, evidence
    of appropriate clinical care or treatment for gender transitioning
    or change, provided by a licensed medical professional.
    ¶19 Finally, we apply the test to the petitions before us and
    conclude Mr. Childers-Gray and Ms. Rice met its requirements.
    We accordingly reverse and remand with instructions to enter
    orders granting their sex-change petitions.
    I. WE HAVE JURISDICTION TO HEAR THIS CASE
    ¶20 Before getting to the meat of the matter, we address our
    jurisdiction to hear it. 12 We have jurisdiction to hear matters that
    are within the scope of the ―judicial power of the state.‖ UTAH
    CONST. art. VIII, § 1. Our case law has ―traditionally‖ limited our
    judicial power ―to the adjudication of disputes.‖ In re Gestational
    Agreement, 
    2019 UT 40
    , ¶ 12, 
    449 P.3d 69
    . So, when ―no dispute
    between opposing parties exists‖—that is, when there is a lack of
    adversariness—we will often, but not always, decline to hear a
    case.13 See 
    id.
     ¶¶ 12–13. Recognizing that this case lacks
    __________________________________________________________
    12Following the structure of our supplemental briefing order,
    in this section we only discuss adversariness concerns. We
    address authority and constitutionality in Parts II and III below.
    13  This court recently engaged in a debate ―regarding the
    source of [the adversariness principle] and the limits of our
    judicial power.‖ Salt Lake Cnty. v. State, 
    2020 UT 27
    , ¶ 37 n.44, 
    466 P.3d 158
    . And that was not the first time such a debate was had.
    Justice Pearce, concurring in In re Gestational Agreement, , opined
    that adversariness might well be a prudential and not a
    jurisdictional concern because the Utah constitution, unlike the
    federal constitution, does not expressly include the ―case or
    controversy language‖ as a limit on our judicial power. 
    2019 UT 40
    , ¶ 86 (Pearce, J., concurring). And while we find much to
    commend in Justice Pearce‘s analysis, we need not reach the issue
    today. This case, like In re Gestational Agreement and Salt Lake
    County, can be resolved without conclusively deciding this
    (continued . . .)
    9
    IN RE SEX CHANGE
    Opinion of the Court
    adversariness, we asked appellants and the Attorney General for
    supplemental briefing on two questions:
    (1) Does the lack of adversariness prevent this Court
    from exercising jurisdiction over this matter? (2) Is an
    application seeking approval of an amendment to a
    birth certificate a matter ‗intended by the framers of
    our constitution to be included in the constitutional
    grant [of power] to the judiciary‘? If not, does it
    resemble other matters our state courts handled at the
    time of statehood?
    (Alteration in original) (citations omitted.)
    ¶21 The appellants and, notably, the Attorney General as
    representative of the State provided identical answers: ―no‖ to our
    first question and ―yes‖ to the second. We agree with their
    answers, but, as we explain below, not necessarily with all of their
    reasoning. We hold that we have jurisdiction over sex-change
    petitions because, historically, Utah courts adjudicated changes to
    legal status or identification, and they did so without
    adversariness. And, as this opinion explains, sex-change petitions
    seek to change the petitioner‘s legal status or identification. As a
    result, sex-change petitions are within the grant of judicial power,
    and we have jurisdiction over them.
    A. Our Constitutional Power Is Not Limited to Adversarial Issues
    ¶22     ―[A]dversariness does not completely define the scope
    of our constitutional power.‖ In re Gestational Agreement, 
    2019 UT 40
    , ¶ 13. Indeed, Utah courts‘ judicial power includes ―functions‖
    that ―were intended by the framers of our constitution to be
    included in the constitutional grant to the judiciary,‖ even if they
    are ―entirely non-adversarial.‖ 
    Id.
     One function that Utah courts
    have had since even before statehood is the authority to decide
    name-change petitions—even when the petition lacks
    adversariness. Sex-change petitions have an identical function to
    question. And so, again, we leave the ―possibil[ity] that, in a
    future case, a historical analysis of the original meaning of the
    Utah Constitution may lead us to rethink the way our case law
    has described the limits of the judicial power‖ but ―decline to
    revisit that case law unnecessarily here.‖ Salt Lake Cnty., 
    2020 UT 27

    Opinion of the Court
    name-change petitions, see infra ¶¶ 40, 42, and so we have
    jurisdiction over them, too.
    ¶23 This opinion holds that the constitutional grant of
    power to the judiciary includes jurisdiction over changes to legal
    status or identification, regardless of the existence (or lack thereof)
    of adversariness.
    ¶24 In arguing against the judiciary‘s jurisdiction to hear
    non-adversarial matters, the dissent draws a distinction between
    adverse ―argument‖ and adverse ―interests.‖ See infra ¶¶ 161–180.
    Though we find no need today to conclusively adjudicate the
    question of whether the Utah Constitution limits our jurisdiction
    to issues involving adversariness, we will briefly address this
    argument. The dissent explains that adverse argument is not
    constitutionally required, given that arguments may be forfeited
    or waived. See infra ¶ 166. So far, we agree. But the dissent next
    posits that ―adverse interests‖ are ―required as a matter of
    historical practice.‖ Infra ¶ 168 (citing Ann Woolhandler, Adverse
    Interests and Article III, 111 N.W. U. L. REV. 1025, 1032 (2017)). In
    other words, the dissent insists that the existence of adverse
    interests—whether stated, waived, or forfeited—is a prerequisite
    for judicial resolution. According to the dissent, cases with
    adverse interests but no adverse briefing are not non-adversarial
    but merely ―uncontested.‖ Infra ¶ 169.
    ¶25 We disagree on several grounds. To begin, our case law
    draws no distinction between adverse arguments and interests
    when determining justiciability. Rather, it looks to whether the
    courts have otherwise been granted the substantive power to
    adjudicate the matter, regardless of adversariness. As recently as
    2019, we‘ve held ―that the traditional principle of adversariness in
    our justiciability jurisprudence does not apply‖ in matters in
    which the courts have been otherwise granted a substantive
    power.14 In re Gestational Agreement, 
    2019 UT 40
    , ¶ 18 (finding that
    __________________________________________________________
    14 The dissent states that in In re Gestational Agreement, this
    court ―reinforced the longstanding general rule that our courts lack
    jurisdiction in the absence of any justiciable controversy between
    adverse parties.‖ Infra ¶ 175 (emphasis added) (quoting In re
    Gestational Agreement, 
    2019 UT 40
    , ¶ 12) (internal quotation marks
    omitted). We disagree with this characterization of the court‘s
    opinion in that case. The court recognized the adjudication of
    adoption rights ―to be a substantive category over which Utah

    11
    IN RE SEX CHANGE
    Opinion of the Court
    courts may validate gestational agreements because the
    ―termination and creation of parental rights [is] a substantive
    power intended to be included in the constitutional grant of
    judicial power to the courts . . . despite the lack of adversariness in
    gestational agreement proceedings‖ (footnote omitted)); see also
    Salt Lake Cnty. v. State, 
    2020 UT 27
    , ¶ 37 n.44, 
    466 P.3d 158
     (noting
    ―that a debate exists regarding the source of th[e] principle
    [against deciding abstract questions] and the limits of our judicial
    power‖).
    ¶26 Perhaps overlooking this case law, the dissent
    significantly relies on a law review article from which it draws the
    distinction and respective jurisdictional requirements of legal
    argument versus interests. See infra ¶¶ 168–72. While we respect
    Professor Woolhandler‘s scholarship, it is not binding on this
    court.
    ¶27 Further, the dissent‘s distinction between adverse
    ―argument‖ and ―interests‖ swallows itself. The dissent refutes
    the notion that naturalization proceedings are non-adversarial,
    pointing to Tutun v. United States, 
    270 U.S. 568
     (1926), for the
    proposition that ―[t]he United States is always a possible adverse
    party‖ in such proceedings. Infra ¶ 174 (alteration in original). But
    a court could always identify a ―possible‖ adverse party for any
    matter before it. The dissent‘s examples regarding the societal
    consequences of today‘s decision, infra ¶ 144, provide an example
    of how mere speculation of possible adverse interests might result
    in a judge‘s unilateral identification of adverse interests beyond
    the briefing by the parties and amicus curiae. To put it another
    way, the dissent differentiates between ―possible adverse
    part[ies]‖ and adverse parties that actually appear to represent
    their interests, ultimately equating ―possible adverse part[ies]‖
    courts had historical power to preside, notwithstanding the
    absence of a controversy between adverse parties.‖ In re
    Gestational Agreement, 
    2019 UT 40
    , ¶ 13 (emphasis added). To this
    end, the court explained ―that the courts had sufficient power to
    participate in proceedings that lacked a dispute between opposing
    parties,‖ 
    id.
     ¶ 16—at least in proceedings involving parental
    rights—and did not further consider whether such proceedings
    are non-adversarial or merely ―uncontested.‖ And so, we cannot
    agree with the dissent‘s belief that In re Gestational Agreement
    reinforced any adversariness requirement.

    Opinion of the Court
    with adverse interests. This conception of adverse interests is so
    expansive as to obviate the need for an explicit requirement of
    ―justiciable controversy.‖
    ¶28 The State and appellants also argue that we have
    jurisdiction over this case because there is a potential for adverse
    litigation here, which is sufficient to invoke ―case or controversy‖
    jurisdiction under United States Supreme Court precedent. See
    Tutun, 
    270 U.S. at 577
    .
    ¶29 It is true that, unlike the statute in In re Gestational
    Agreement, the statute here does not explicitly require
    nonadversariness. Compare UTAH CODE § 78B-15-803(2)(e) (2008),15
    with id. § 26-2-11, and id. § 42-1-1. But because sex-change petitions
    resemble other petitions over which Utah courts had jurisdiction
    at founding, we have jurisdiction to address this matter and
    therefore need not address the potential adversariness argument.
    See infra ¶¶ 40–43. We do note, however, the existence of a serious
    debate on this topic.16

    IN RE SEX CHANGE
    Opinion of the Court
    ¶30 The dissent appears to overlook this debate, insisting
    instead that we are establishing that ―our courts can adjudicate
    any case over which we have been granted . . . substantive power
    by the legislature, at least where the decision amounts to a change
    in a person‘s legal status or identification.‖ Infra ¶ 185 (emphasis
    added) (quoting this opinion) (citation omitted) (internal
    quotation marks omitted). Not so. As we emphasized in In re
    Gestational Agreement, this ―substantive power‖ does not flow
    from the legislature; rather, it was intended and understood ―to
    be included in the constitutional grant of judicial power to the
    courts . . . despite the lack of adversariness.‖ 
    2019 UT 40
    , ¶ 18. In
    sum, we stand behind our position that adversariness is not a
    requirement for justiciability in matters involving changes to legal
    status or identification.
    B. Utah Courts Historically Have Had Jurisdiction to Adjudicate
    Changes to Legal Status or Identification
    ¶31 Having shown that adversariness is not a limitation on
    the constitutional grant of power to the courts, at least with
    respect to a person‘s legal status or identification, we now turn to
    whether adjudication of sex-change petitions is within the
    ―judicial power‖ granted to the judiciary by article VIII, section 1
    of the Utah Constitution. We first explain why our supplemental
    briefing order, asking if our framers could have intended courts to
    have a constitutional grant to approve ―an amendment to a birth
    certificate,‖ was not quite the right inquiry. Then we address the
    proper inquiry—whether our progenitors understood the courts
    to have power to hear petitions for sex change. We hold that,
    while sex-change petitions were not specifically contemplated at
    the time of statehood, the judicial power nonetheless includes the
    power to hear such petitions because they ―resemble other
    matters our state courts handled at the time of statehood,‖
    specifically name-change petitions.
    ¶32 Whether anyone around at the time of the adoption of
    the Utah Constitution intended to include adjudication of a petition
    to amend a birth certificate in the grant of judicial power is the
    only after [statutory] provisions for notice to, and potential
    appearance by, the United States‖).
    14
    Cite as: 
    2021 UT 13
    Opinion of the Court
    wrong inquiry in this case.17 That is because sex-change and
    name-change petitions do not ask the court to approve an
    amendment to a birth certificate. Rather, sex-change and
    name-change petitions today—like the historical name-change
    petitions we discuss below—ask a court to approve a legal change
    to the petitioner‘s name or sex, i.e., a change of legal status or
    identification. It is only after the court approves that change that a
    petitioner may choose to request an amendment to their birth
    certificate from the state registrar. UTAH CODE § 26-2-11.
    ¶33 The proper inquiry, thus, is whether a petition for sex
    change—not a petition to amend a birth certificate—is a matter
    ―intended by the framers of our constitution to be included in the
    constitutional grant [of power] to the judiciary.‖ (Alteration in
    original.)
    ¶34 That brings us to the next step of our inquiry. We show
    that petitions for a sex change ―resemble other matters our state
    courts handled at the time of statehood‖: petitions for name
    changes. Crucial to this step is the understanding that ―[t]he Utah
    Constitution enshrines principles, not application of those
    principles.‖ South Salt Lake City v. Maese, 
    2019 UT 58
    , ¶ 70 n.23,
    
    450 P.3d 1092
    . We employ analogies not because doing so is
    necessary to discern a principle, but because it helps us to better
    understand those fundamental principles. Accordingly, we
    discuss Utah courts‘ historical power to preside over name-
    change petitions. Then we explain that the adjudication of a
    name-change petition, when it comes right down to it, is merely
    one part of a broader ―substantive category over which Utah
    courts had historical power to preside‖: the adjudication of
    __________________________________________________________
    17  Neither the framers of our constitution nor the general
    public specifically contemplated including adjudication of a
    petition to amend a birth certificate in the judiciary‘s
    constitutional grant because, simply put, birth certificates did not
    exist in 1896. And so, birth-certificate changes were not
    contemplated at the time. See Birth Records, UTAH DIV. OF

    IN RE SEX CHANGE
    Opinion of the Court
    changes to the legal status or identification of an individual. In re
    Gestational Agreement, 
    2019 UT 40
    , ¶ 13. As a result, adjudicating
    changes to the legal status or identification of individuals was a
    ―function[] . . . intended by the framers of our constitution to be
    included in the constitutional grant to the judiciary.‖ 
    Id.
     As we
    explain below, sex-change petitions are petitions to change the
    legal status or identification of an individual because they are
    analogous to name-change petitions, and so adjudicating them is
    a function that falls squarely within the judicial power.
    ¶35 To put it simply, name-change petitions seek to change
    the legal status or identification of an individual because a name
    is one of an individual‘s numerous legal attributes. These legal
    attributes, some of which are indicated on a birth certificate, may
    serve as conditions that shape an individual‘s opportunities and
    obligations, such as marital or civil status. See, e.g., Obergefell v.
    Hodges, 
    576 U.S. 644
    , 669–70 (2015) (―[J]ust as a [married] couple
    vows to support each other, so does society pledge to support the
    couple . . . . [States] have throughout our history made marriage
    the basis for an expanding list of governmental rights, benefits,
    and responsibilities.‖). Or they may serve for purposes of
    identification, such as name, sex, and age or birthdate. See, e.g.,
    State v. Chism, 
    2005 UT App 41
    , ¶ 18, 
    107 P.3d 706
     (noting that the
    date of birth reflected on a state-issued identification card ―is
    reliable and presumptively establishes the bearer‘s age despite his
    or her somewhat younger physical appearance‖); infra ¶ 196 n.94
    (noting that a birth certificate ―serve[s] as proof of an individual‘s
    age, citizenship, status, and identity‖ (alteration in original)
    (citation omitted)). Thus, information contained in a government-
    issued identification document—name, sex, date of birth,
    permanent address—has legal significance.
    ¶36 Before evaluating the similarities between sex-change
    and name-change petitions, we address the history of Utah courts‘
    adjudication of name-change petitions. In Utah, an individual has
    a ―common law right to adopt another name at will.‖ In re Porter,
    
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
    ; In re Cruchelow, 
    926 P.2d 833
    , 834
    (Utah 1996); accord Moskowitz v. Moskowitz, 
    385 A.2d 120
    , 122
    (N.H. 1978) (―[A]t common law a person could adopt another
    name at will.‖); Smith v. U. S. Cas. Co., 
    90 N.E. 947
    , 950 (N.Y. 1910)
    (―The elementary writers are uniform in laying down the rule that
    at common law a man may change his name at will.‖); 57 AM. JUR.
    2D Name § 16 (2020) (―A person has a common-law right to
    assume or use any name that he or she lawfully chooses.‖); G.S.

    Arnold, Personal Names, 15 YALE L.J. 227, 229 (1906) (―[W]ithout
    statutes, any person may at will change [their] name.‖).
    ¶37 At common law, the right to change one‘s name did not
    require state assistance. See Smith, 90 N.E. at 950 (―At common law
    a man may lawfully change his name, or by general usage or habit
    acquire another name than that originally borne by him, and this
    without the intervention of either the sovereign, the courts, or
    Parliament.‖ (quoting 21 AM. & ENG. ENCYC. OF LAW (2d Ed.)
    311)). But state recognition, through courts, of a name change
    gave ―greater sanction to it, and ma[de] it more notorious.‖ Davies
    v. Lowndes (1835) 131 Eng. Rep. 1247, 1255. Consequently, courts
    have long held the common-law authority to adjudicate this
    individual right. See, e.g., Bearbrook v. Read (1600) 1 Brownl. &
    Golds. 47 (―The name of Confirmation must stand, for Sir Francis
    Grady was christened Thomas, and confirmed Francis, by that
    name he must be called.‖).
    ¶38 State legislatures have enacted procedures for courts to
    adjudicate name-change petitions. These statutes do ―not repeal
    the common law by implication or otherwise‖; rather, they serve
    as powerful affirmations of, and in aid of, the courts‘ common-law
    authority. Smith, 90 N.E. at 950 (citation omitted); see also In re
    Porter, 
    2001 UT 70
    , ¶ 8 (―Statutes similar to sections 42-1-1 and -2
    are recognized to merely provide a codified process to aid an
    individual‘s common law right to adopt another name at will.‖
    (citing In re Cruchelow, 926 P.2d at 834)); In re Knight, 
    537 P.2d 1085
    , 1086 (Colo. App. Ct. 1975) (―Statutes setting forth
    procedures to be followed in changing a name merely provide an
    additional method for making the change.‖); Moskowitz, 385 A.2d
    at 122 (holding that the statutes did not ―abrogate or supersede
    the common law, but merely affirm[ed] and aid[ed] it‖).
    ¶39 Utah‘s territorial legislature was no different: It
    formally vested the right to adjudicate name-change petitions
    with Utah courts. See Of Change of Names, § 1128, 
    1884 Utah Laws 354
     (―Applications for change of names must be heard and
    determined by the district courts.‖); see also 
    id.
     § 1129; Of Change
    of Names, §§ 3861–62, 
    1888 Utah Laws 422
    . The State legislature
    did the same. See Names, §§ 1545–47, 
    1898 Utah Laws 394
    . But,
    like in all other jurisdictions, these legislative actions were
    ―merely‖ to ―aid‖ the common-law right. In re Cruchelow, 926 P.2d
    at 834. And our courts have continuously used common-law
    17
    IN RE SEX CHANGE
    Opinion of the Court
    standards to adjudicate this right. See In re Porter, 
    2001 UT 70
    ,
    ¶¶ 7–11; In re Cruchelow, 926 P.2d at 834–35.18
    __________________________________________________________
    18  Before 1884, the territorial legislature had heard name-
    change applications and approved them in the form of ―private
    laws.‖ See, e.g., Change of Names Act Mar. 13, 1884, ch. LII, 
    1884 Utah Laws 136
     (changing the names of six people); Name Change
    Act of Feb. 20, 1878, 
    1878 Utah Laws 166
     (changing the name of
    Ephraim Powell to Ephraim Brettel Bolton); Name Change Act of
    Jan. 30, 1872, ch. I, § 1, 
    1872 Utah Laws 1
     (surname change of five
    people). But the 1896 Constitution expressly took away any
    authority that the territorial legislature might have had to change
    names. UTAH CONST. art. VI, § 26(2) (1896) (―The Legislature is
    prohibited from enacting any private or special laws . . .
    [c]hanging the names of persons.‖).
    This historical detail raises the question of whether before
    1884, name-change petitions were of a legislative province rather
    than a judicial one. The answer is no.
    Aside from the sources we describe above that point to courts‘
    common-law authority over name-change petitions, we find
    support for this proposition in our territorial case law about
    divorce decrees (another personal legal status change). Although
    we have no case law from the period addressing name changes,
    we do have case law about divorce decrees—another area
    forbidden for legislative action in the 1896 Constitution. See UTAH
    CONST. art. VI, § 26(1) (1896). Our territorial supreme court
    explained that any legislative divorce decree was ―granted in the
    exercise of judicial power; that they were recognized as judicial
    subjects and not as legislative.‖ In re Est. of Higbee, 
    5 P. 693
    , 697
    (Utah 1885). And our early case law suggests that the territorial
    legislature had invaded the judicial department‘s functions on
    other occasions. See, e.g., In re Handley’s Est., 
    49 P. 829
    , 831 (Utah
    1897) (―If we were to affirm the validity of the law in question, we
    would, in effect, say that the legislature may exercise judicial
    powers.‖).
    Building on Higbee, it is clear that article VI, section 26 of the
    1896 Utah Constitution was meant to respect separation of powers
    and was mandated by article V, section 1, which established three
    separate departments of government and forbade any department
    from ―exercis[ing] any functions appertaining to either of the
    others.‖ UTAH CONST. art. V, § 1. Therefore, if anything can be

    Opinion of the Court
    C. We Have Jurisdiction to Adjudicate Sex-Change Petitions Because
    They Are Changes to Legal Status or Identification
    ¶40 Having settled the question of this court‘s power to
    adjudicate non-adversarial name-change petitions as changes to
    legal status or identification, we turn to sex-change petitions. We
    hold that sex-change petitions are likewise within the judiciary‘s
    jurisdictional purview. Sex-change petitions are closely analogous
    to name-change petitions because they are both changes to a
    person‘s legal status or identification. See, e.g., In re Heilig, 
    816 A.2d 68
    , 82 (Md. 2003) (stating that actions to change incorrect
    information on a person‘s birth certificate ―relate principally to
    the legal status or identification of an individual‖). At birth, a
    third party gives a person‘s name and designates their sex. But a
    person experiencing gender dysphoria later in life may seek to
    update their legal status or identification by petitioning for a
    name or sex change. These changes are not just symbolic; they
    help avoid the confusion that can result when people hold
    themselves out as having one name or as being one sex but have
    government identification that says differently.19
    ¶41 Other courts have observed the similarity between
    name changes and sex changes and have deduced from it that the
    procedures to effect such changes should also be similar. See, e.g.,
    Radtke v. Misc. Drivers & Helpers Union Loc. No. 638 Health, Welfare,
    Eye & Dental Fund, 
    867 F. Supp. 2d 1023
    , 1025–26, 1033 (D. Minn.
    2012) (explaining that Wisconsin Statutes section 69.15(1) provides
    that a birth-certificate amendment could be made by the state
    registrar if a court issued an order providing for ―name change
    with sex change,‖ and consequently mentioning that a Wisconsin
    state court decision granted such order); In re McDannell, 
    2016 WL 482471
    , at *8 (Ct. Com. Pl. Del. Feb. 5, 2016) (holding that ―since
    the Court of Common Pleas is vested with the authority to change
    names, it is only logical that it is a court of competent jurisdiction
    to consider the petition [for sex change]‖ when both changes are
    learned from the legislative acts granting name changes, it is that
    for a limited time our territorial legislature performed a judicial
    function, which it expressly disclaimed in the decade leading up
    to, and in, the Utah Constitution.
    19  Indeed, condoning such confusion by refusing a valid
    petition for a name or sex change would obviate the very purpose
    of legal identification. See supra ¶ 35.

    of birth‖); In re Heilig, 816 A.2d at 82–83 (equating the two
    changes). We do the same.
    ¶42 The dissent resists the analogy between name changes
    and sex changes, see infra ¶¶ 181–83, suggesting that name change
    proceedings are a unique ―carve-out.‖ Infra ¶ 183. But such is not
    the nature of reasoning by analogy. Our analogy rests on the
    function shared by name- and sex-change petitions—that is,
    changes to legal status or identification. Buttressing our analogy is
    that the statute positions name and sex change jointly, UTAH CODE
    § 26-2-11, and that other courts before us have found the analogy
    compelling and relevant. And in another exchange with the
    dissent‘s author, we explained that ―analogies only require
    ‗similar[ity] in some ways.‘ Requiring identical circumstances
    obviates our ability to use analogies.‖ Ipsen v. Diamond Tree
    Experts, Inc., 
    2020 UT 30
    , ¶ 19 n.13, 
    466 P.3d 190
     (first alteration in
    original) (emphasis added) (quoting Analogy, BLACK‘S LAW
    DICTIONARY (11th ed. 2019)). By way of example, in the past we
    held that ―parental termination proceedings‖ are ―‗analogous to
    [a] court‘s termination of the marriage relationship between a
    husband and wife.‘‖ D.A. v. State (In re W.A.), 
    2002 UT 127
    , ¶ 22,
    
    63 P.3d 607
     (alteration in original) (quoting In re Interest of M.L.K.,
    
    768 P.2d 316
    , 319 (Kan. Ct. App. 1989)). We do not see these two
    proceedings as identical. Instead, we base the analogy on the fact
    that ―[i]n both custody and termination proceedings, the court
    principally determines where and with whom a child should or
    should not live.‖ In re Interest of M.L.K., 
    768 P.2d at 319
    . The same
    is true in this case. The district court is called to approve a change
    in a designation both in the name- and sex-change context.
    Likewise, our search here is for analogies to situations that would
    have been understood to be ―included in the constitutional grant
    of judicial power to the courts,‖ In re Gestational Agreement, 
    2019 UT 40
    , ¶ 18, such that we can appropriately apply the existing
    common law to those situations. We do not search for our
    20
    Cite as: 
    2021 UT 13
    Opinion of the Court
    forebearers‘ specific understanding of the current situation.20 If we
    had that, we would not need to use analogies.
    ¶43 In summary, deciding a petition for sex change, much
    like one for a name change, involves adjudication of a change in
    the legal status or identification of an individual. Our progenitors
    intended for the adjudication of a person‘s legal status or
    identification to be ―a substantive power . . . included in the
    constitutional grant of judicial power to the court.‖ 
    Id.
     And so, ―it
    is appropriate for our courts‖ to adjudicate changes to the legal
    status or identification of an individual—specifically, name- and
    sex-change petitions—even if they lack adversariness.21 See 
    id.
    __________________________________________________________
    20 In further support of the analogy, we note that this court
    spoke broadly in In re Gestational Agreement, recognizing that
    ―[c]ertain functions that our courts perform may be both entirely
    non-adversarial and still appropriately fall within the ‗judicial
    power.‘‖ 
    2019 UT 40
    , ¶ 13.
    21 The dissent chides us for not inviting adversarial or amicus
    briefing. Infra ¶¶ 198–200. But we ordered supplemental briefing
    on several key constitutional questions. The order solicited the
    views not only from the petitioners but also from the Attorney
    General‘s Office on the questions presented. All supplied
    supplemental briefing, and, notably, the views of the Attorney
    General in its amicus brief were largely in line with the views
    expressed by the court today. The dissent is advocating for yet
    another round of briefing, which would significantly delay the
    resolution of this three-year-old matter. That is something we are
    unwilling to do.
    But our disinclination to engage in another round of briefing
    must not be misunderstood as a prioritizing of certain interests
    over others. We do not outright reject the possibility that certain
    sex-change petitions may involve adverse interests. Even though
    lack of adversariness is not a bar to our jurisdiction in changes to
    legal status or identification, adverse interests may certainly play
    a role, though not in the way the dissent suggests: If a third
    party‘s rights are affected by a court‘s order in a name- or sex-
    change petition, the third party may have standing to file suit
    with respect to the specific interest affected. See, e.g., Parents for
    Priv. v. Dallas Sch. Dist. No. 2, 
    326 F. Supp. 3d 1075
    , 1081–82 (D. Or.

    Opinion of the Court
    Therefore, we have jurisdiction to resolve this appeal, and we do
    so now.
    II. UTAH COURTS HAVE AUTHORITY
    TO ADJUDICATE SEX-CHANGE PETITIONS
    ¶44 Having established our jurisdiction over this case, we
    turn to whether Utah courts have authority to hear sex-change
    petitions. By authority here we mean a framework that allows
    Utah courts to adjudicate a particular matter—in this case, sex-
    change petitions. Such framework can be statutory- or common-
    law-based. This question is different than our jurisdictional
    inquiry above in Part I, which focuses on whether a Utah court
    has judicial power to hear a non-adversarial case, like a name- or
    sex-change petition.
    ¶45 The district court here held that it lacked authority to
    adjudicate the petitions and denied them. In its order denying Mr.
    Childers-Gray‘s petition, it explained that there is ―no statute in
    the State of Utah which sets forth either standards or procedures
    under which the court may consider such‖ petition. The district
    court concluded that this legislative silence meant that the
    ―standards or procedures‖ ―have simply not yet been
    determined.‖ And in denying Ms. Rice‘s petition, the district court
    stated that because of these reasons, ―it does not have the
    authority to grant the request.‖ Appellants argue that district
    courts do have the authority to adjudicate sex-change petitions.
    We agree with appellants and conclude that the district court
    erred.
    ¶46 The legislature has provided through statute that an
    individual can petition for a sex change and that district courts
    have jurisdiction to decide such a petition. The plain language of
    the statute is ―the first step of statutory interpretation.‖ State v.
    Malo, 
    2020 UT 42
    , ¶ 22, 
    469 P.3d 982
     (quoting Garrard v. Gateway
    policy allowing transgender students to use the ―restrooms, locker
    rooms, and showers that match their gender identit[ies]‖ on a
    number of claims (excluding a claim against federal defendants
    for violation of the Administrative Procedure Act)). In other
    words, if there comes a time when adverse interests ripen, the
    judicial system will address those rights. We see no reason in
    prohibiting our jurisdiction over sex-change petitions merely in
    anticipation of currently unripe interests.

    Opinion of the Court
    Fin. Servs., Inc., 
    2009 UT 22
    , ¶ 11, 
    207 P.3d 1227
    ). Here, the plain
    language of Utah Code section 26-2-11 presupposes judicial
    authority to adjudicate sex-change petitions. Utah Code section
    26-2-11(1) states that ―[w]hen a person born in this state has a
    name change or sex change approved by an order of a Utah
    district court . . . a certified copy of the order may be filed with the
    state registrar with an application form provided by the
    registrar.‖ This language unambiguously assumes there is judicial
    authority over the adjudication of name- and sex-change petitions.
    It purports to grant the district courts no new powers. Thus, all
    that Utah Code section 26-2-11(1) does is, as the Attorney General
    eloquently put it in its amicus briefing, ―assume[] that courts have
    preexisting jurisdiction to address name- and sex-change
    petitions.‖ Our ―judicial humility . . . requires us to refrain from
    diminishing‖ this assumption. Bostock v. Clayton Cnty., 
    140 S. Ct. 1731
    , 1753 (2020).
    ¶47 The statute aids courts in the exercise of their
    jurisdiction to decide petitions for name and sex changes, and
    though it does not provide a test to do so, this is not a bar to our
    authority. That neither Utah Code section 26-2-11 nor any other
    statute contains explicit standards or procedures for petitions for
    sex change is of no moment because we find that ―the legislature
    did not intend‖ such silence to obviate the assumption that
    district courts have the authority to adjudicate sex-change
    petitions. See Cox v. Laycock, 
    2015 UT 20
    , ¶ 41, 
    345 P.3d 689
    .
    ¶48 Approaching this gap-filling assignment, we ―seek the
    intent of the legislature,‖ id. ¶ 42, because ―[i]t is the duty of this
    court, according to its best knowledge and understanding, to
    declare the law as it finds it, and determine the intent and purpose
    thereof from the language used by the Legislature in expressing
    such purpose and intention.‖ Eames v. Bd. of Comm’rs, 
    199 P. 970
    ,
    972 (Utah 1921). We do so by ―analyz[ing] the act in its entirety
    and harmoniz[ing] its provisions in accordance with the
    legislative intent and purpose.‖ Laycock, 
    2015 UT 20
    , ¶ 42 (quoting
    Mariemont Corp. v. White City Water Improvement Dist., 
    958 P.2d 222
    , 225 (Utah 1998)).
    ¶49 The legislature‘s choice to address name and sex change
    in tandem is a determinative feature of how district courts should
    address sex-change petitions and of our gap-filling mission. Of
    much importance in this decision is the original statutory text
    from 1975: ―Whenever a person born in this state has their name
    and/or sex change approved by an order of a court [of any State or
    23
    IN RE SEX CHANGE
    Opinion of the Court
    U.S. Territory,] . . . a certified copy of the court order may be filed
    with the office of the state registrar upon an application form
    provided by such registrar.‖ 
    1975 Utah Laws 222
     (emphasis
    added). The statute then went on to direct the Board of Health to
    ―establish fees to be received for preparation of . . . amended birth
    certificates provided in [the original statutory provision].‖ 
    Id.
    ¶50 The legislature knowingly and purposefully combined
    name and sex changes together. ―[W]hen a word or phrase is
    transplanted from another legal source, whether the common law
    or other legislation, it brings the old soil with it.‖ Maxfield v.
    Herbert, 
    2012 UT 44
    , ¶ 31, 
    284 P.3d 647
     (citation omitted) (internal
    quotation marks omitted). When the legislature transplanted
    ―name change‖ from the common law, it statutorily planted both
    ―sex change‖ and ―name change‖ in the latter‘s ―old soil.‖
    Accordingly, it meant for the same type of evaluation to control in
    both changes. And so we fill the gap in standard for sex-change
    adjudication with the common-law principles that control name-
    change adjudication, with the appropriate adjustments, to ―give
    effect to the legislature‘s intent in light of the purpose that the
    statute was meant to achieve.‖ Monarrez v. Utah Dep't of Transp.,
    
    2016 UT 10
    , ¶ 11, 
    368 P.3d 846
     (quoting Biddle v. Wash. Terrace
    City, 
    1999 UT 110
    , ¶ 14, 
    993 P.2d 875
    ). In filling this statutory gap
    with common-law procedure, we are merely fulfilling our judicial
    duty to give effect to—not to usurp—the statute.22
    __________________________________________________________
    22  Our cases state that our common-law authority is not
    dependent on or limited by a statutory provision unless it clearly
    says so. See, e.g., Anderson v. Bell, 
    2010 UT 47
    , ¶ 16 n.5, 
    234 P.3d 1147
     (explaining that not ―every instance that a statutory scheme
    and the common law converge‖ will ―necessarily mean the
    legislature has abolished the common law‖), superseded on other
    grounds by statute, UTAH CODE § 20A-9-502; Williamson v. Farrell,

    judgments ―even apart from their authority set out in‖ statute).

    Opinion of the Court
    ¶51 In the name-change context, the Utah Code works in
    tandem with our common-law authority to adjudicate name
    changes. See supra ¶¶ 36–39. Utah Code section 42-1-1 enumerates
    the content of a name-change petition, and section 42-1-2 tells the
    court when it may grant a name-change order. Its plain language
    requires the district court to determine, among other things,
    whether the petitioner has presented adequate proof that proper
    cause exists for granting the name change. Id. But it is our case law
    that imbues the term ―proper cause‖ with meaning, using
    common-law precedents. Indeed, we have held that ―proper
    cause‖ means that a petition is not ―sought for a wrongful or
    fraudulent purpose.‖ In re Porter, 
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
    (quoting In re Cruchelow, 
    926 P.2d 833
    , 834 (Utah 1996)). This
    standard is not mentioned in the statute, but it does not matter
    because the statute, as this court explained in In re Porter, ―merely
    provide[s] a codified process to aid [the] common law right to
    adopt another name at will.‖ 
    2001 UT 70
    , ¶ 8; see also In re
    Cruchelow, 926 P.2d at 834.
    ¶52 Similarly, we have injected meaning into statutory tests
    based on common-law principles in other areas, such as marital
    status and declaratory judgments. See Whyte v. Blair, 
    885 P.2d 791
    ,
    794–95 (Utah 1994) (holding that ―in determining whether a
    relationship satisfies the requirements of [the common-law
    marriage statute], numerous factors should be considered,‖ before
    turning to explain these factors; as common-law principles, these
    factors are distinct from the enumerated statutory elements and
    indicate the kind of evidence that may serve to meet the statutory
    elements); Williamson v. Farrell, 
    2019 UT App 123
    , ¶ 17, 
    447 P.3d 131
     (mentioning that the ―four ‗threshold elements‘ for
    711; Olseth v. Larson,

    IN RE SEX CHANGE
    Opinion of the Court
    declaratory judgment actions‖ used by courts ―do not appear
    anywhere in the Act‖).
    ¶53 We are not ―mak[ing] pure policy out of whole cloth.‖
    Infra ¶ 255. The fact that a field of law, such as sex-change
    petitions, is not governed by its own common law is no bar to our
    authority. Our cited cases do not stand for the proposition that
    when a term is ―transplanted‖ with its ―old soil‖ to a new legal
    context, only that term may be planted in that ―soil.‖ Rather, our
    only established limitation is that we do not engage in a common-
    law analysis that conflicts with statutory guidance. See Rawcliff v.
    Anciaux, 
    2017 UT 72
    , ¶ 14, 
    416 P.3d 362
     (―[T]he common law
    assists in defining the scope of the [fiduciary] duty, as long as the
    duty itself is identified by the plain language of the statute and
    our common law does not conflict with any statutory guidance on
    the scope of that duty.‖) None of this disagrees with the dissent
    that our case law ―presuppose[s] the existence of established
    bodies of common law to be retained, or to avoid abolishing.‖ Infra
    ¶ 248. Of course, the common law must exist in order for a court
    to engage with it, but such a proposition does not preclude our
    ability to apply traditional bodies of common law to analogous
    and statutorily related terms. Doing so is not ―mak[ing] policy out
    of whole cloth‖ but rather is applying existing name-change
    common law to the statutorily and precedentially related sex-
    change field.23
    __________________________________________________________
    23 Because there is no common law specific only to sex-change
    petitions, the dissent posits that the ―administrative concept‖ of
    sex change applies. Infra ¶ 278. The dissent relies on New Park
    Mining Co. v. State Tax Comm’n, 
    196 P.2d 485
     (Utah 1948), and Fed.
    Deposit Ins. Corp. v. Phila. Gear Corp., 
    476 U.S. 426
     (1986), to
    support its theory that ―[w]here our legislature uses terms that
    have a settled ‗administrative interpretation‘ in a particular field,
    that interpretation is understood to be carried forward in the
    statute.‖ Infra ¶ 277. But the Office of Vital Records and Statistics
    has never made such an interpretation. Further, the Office is not
    tasked with making any decisions regarding sex designations;
    rather, it responds without discretion to court orders pursuant to
    Utah Code section 26-2-11(2). There is no room for any
    administrative interpretation under this statutory regime. Further,
    sex is not designated in the first instance by the Office; rather, sex
    is designated (primarily) by medical professionals who

    Opinion of the Court
    ¶54 Neither are we running afoul of the non-delegation
    doctrine. As discussed in detail above, supra ¶¶ 31–39, the
    legislature has recognized the jurisdiction of the courts to
    adjudicate non-adversarial changes to legal status or
    identification. We are not ―suggesting that there is no legislative
    standard that governs‖ sex-change petitions, infra ¶ 306, simply
    because we may properly apply the common law associated with
    name-change petitions. The legislature may choose to enact a
    substantive standard for sex changes at any time, but so far it has
    not done so. 24 Section 26-2-11 is a statute enacted in aid of the
    court‘s common law authority. And should the legislature find
    issue with our decision today, it has the authority to override the
    common law with statute. Thus, we are not overstepping our
    constitutionally-delegated powers but rather acting with the
    authority the legislature has passed to the courts under section 26-
    2-11. We find additional support for our conclusion in the manner
    that other jurisdictions, including those with similar statutes, have
    addressed their authority to adjudicate sex-change petitions.
    ¶55 The Maryland Court of Appeals (Maryland‘s highest
    court) addressed a statute that ordered the secretary of health to
    amend a birth certificate ―[u]pon receipt of a certified copy of an
    order of a court of competent jurisdiction indicating the sex of an
    individual born in this State has been changed . . . .‖ In re Heilig,
    
    816 A.2d 68
    , 82 (Md. 2003) (alteration in original) (quoting MD.
    CODE ANN., Health – General, § 4-214(b)(5) (West 2002) (amended
    2015)).25 The Court explained that ―the statute, along with other
    statutes in the subtitle of which it is a part, evidences a clear
    presumably are not versed in the nuances of administrative
    definitions in the law.
    24   The legislature unquestionably knows how to place
    substantive restrictions on our exercise of common law power.
    For example, with respect to name-change petitions, the
    legislature has provided in Utah Code section 77-41-105(8)(a) that
    a court may only grant a name change of someone on the sex and
    kidnap offender registry ―if the name change is not contrary to the
    interests of the public.‖ See also infra ¶ 80.
    25In 2015, Maryland opted to allow persons to change their sex
    designation on their birth certificate through an administrative
    process, without a court order. See 
    2015 Md. Laws 2538
     (codified
    at MD. CODE ANN., Health – General, § 4-214(b)(5) (West 2021)).

    recognition by the General Assembly that a person‘s gender can
    be changed and that there are courts with jurisdiction to consider
    and determine whether that has occurred.‖ Id. at 82.
    ¶56 The Indiana court of appeals dealt with a statute vaguer
    than section 26-2-11 in In re Change of Birth Certificate, 
    22 N.E.3d 707
    , 709 (Ind. Ct. App. 2014). The Indiana statute allowed ―[t]he
    state department [to] make additions to or corrections in a
    certificate of birth on receipt of adequate documentary evidence.‖
    Id. at 708 (quoting IND. CODE § 16-37-2-10(b)). The court found that
    this language ―provides general authority for the amendment of
    birth certificates, without any express limitation (in the statute or
    elsewhere) regarding gender amendments.‖ Id. at 709. The court
    then relied on that statute, ―as well as the inherent equity power
    of a court of general jurisdiction,‖ to hold that trial courts have
    ―authority to grant‖ sex-change petitions. Id.; see also In re
    Clemmer, 
    135 N.E.3d 168

    ¶57 We recognize that not all courts have found authority in
    such generally articulated statutes as did the Maryland and
    Indiana courts. But we find those courts‘ decisions
    distinguishable. In In re McReynolds, the Texas Court of Appeals
    interpreted a statute that provided that to prove their identity and
    age when applying for a marriage license, a person may present
    ―a court order relating to the applicant‘s name change or sex
    change.‖

    , 887 (Tex. Ct. App. 2016) (quoting TEX.
    FAM. CODE § 2.005(b)(8)). The Texas court of appeals opined that
    because the legislature enacted procedures for name-change
    petitions but not for sex-change petitions, it did not ―intend[] to
    create a new justiciable right of action for a sex change order‖ and
    that the legislature ―would not have left it to the judicial branch to
    define the right‘s substantive elements and procedures.‖ Id. To
    support its outcome, the court then revisited and distinguished
    several prior Texas decisions that presupposed such authority. Id.
    at 889–90. But, as the court of appeals itself explained, its decision
    did not foreclose sex changes in the state. Id. at 885 n.2. Unlike in
    Utah, Texas law does not seem to require a court order to amend a
    birth certificate. Rather, Texas Health and Safety Code section
    191.028(b) provides for an administrative procedure to amend a
    birth certificate. The statute prescribes that ―[a]n amending
    certificate may be filed to complete or correct a record that is
    incomplete or proved by satisfactory evidence to be inaccurate.
    The amendment must be in a form prescribed by the department.‖

    Opinion of the Court
    McReynolds, 502 S.W.3d at 885 n.2. Additionally, the decision
    ignores the endurance of the common-law right of a person to
    change their name and, consequently, their legal status, even
    when there is no legislation on the matter. Therefore, the basis for
    adjudicating sex-change petitions is different in Utah.
    ¶58 At least one Ohio court has also held that courts may
    not adjudicate sex-change petitions. See In re Ladrach, 
    513 N.E.2d 828
    , 832 (Stark Cnty. Ohio Prob. Ct. 1987). But Ohio law is
    manifestly different than Utah law. Indeed, an Ohio statute grants
    the executive the authority to amend birth certificates for error
    correction. See OHIO REV. CODE ANN. § 3705.22 (West 2021)
    (providing that a birth certificate shall be amended once the
    director of health establishes the alleged facts requiring the
    amendment). Only if one seeks to amend the same data a second
    time is a court order required. See id. And so, in Ohio, a person
    does not need a court order to change their birth certificate (the
    first time around), and the case law from Ohio is immaterial. As
    we explain below, Ohio‘s executive, however, does not allow such
    change. See infra ¶ 59 n.26.
    ¶59 Bottom line, we have common-law authority to
    adjudicate sex-change petitions because they are petitions to
    change one‘s legal status or identification, just like name-change
    petitions. And we have the authority to adjudicate name-change
    petitions. This conclusion is supported by the legislature‘s
    assumption in Utah Code section 26-2-11 and is further reinforced
    by decisions in other jurisdictions. We accordingly hold that Utah
    district courts have authority to adjudicate sex-change petitions.26

    IN RE SEX CHANGE
    Opinion of the Court
    III. THE POLITICAL QUESTION DOCTRINE
    AND ARTICLE V OF THE UTAH CONSTITUTION
    ¶60 Having concluded that district courts have the
    jurisdiction and authority to adjudicate sex-change petitions, we
    move on to determining whether their doing so violates the
    political question doctrine or article V, section 1 of the Utah
    Constitution.
    ¶61 First, we must ask whether adjudicating sex-change
    petitions is a nonjusticiable political question. Second, we ask
    whether adjudicating sex-change petitions is unconstitutional
    under the ―Separation of Powers‖ clause of the Utah Constitution.
    See UTAH CONST. art. V, § 1. The district court answered both
    questions in the affirmative, finding that there is ―no statute in the
    State of Utah which sets forth either standards or procedures
    under which the court may consider such‖ petition, and that
    setting standards or procedures would be a legislative task and
    not a judicial one.
    ¶62 The focus of both the district court and our
    supplemental briefing question was whether the adjudication of
    sex-change petitions is a political question—that is, whether it is
    an ―interference in matters wholly within the control and
    discretion of other branches of government,‖ Skokos v. Corradini,
    
    900 P.2d 539
    , 541 (Utah Ct. App. 1995) (citing e.g., Baker v. Carr,
    
    369 U.S. 186
     (1962))—given the ―absence of‖ ―procedural and
    substantive criteria for granting of a sex-change order.‖ Relatedly,
    we asked the parties to brief whether, when district courts
    adjudicate sex-change petitions, they ―exercise . . . functions
    appertaining to either‖ the legislative or executive departments of
    government, thus violating the separation-of-powers requirement
    in article V, section 1 of the Utah Constitution. Appellants, of
    course, argued that there is no constitutional violation. And the
    Attorney General, representing the State, declined to answer the
    question, citing our presumption of constitutional validity ―based
    on fundamental separation-of-powers precepts.‖ (Internal
    quotation marks omitted.)
    court order, courts in that state refuse to issue such orders.‖
    (citations omitted)). But this last observation about Ohio seems
    only partially correct since, as we explain above, a court order is
    needed there only to amend a birth certificate a second time
    around. See supra ¶ 58.

    Opinion of the Court
    ¶63   Ultimately, our answer to both queries is a resounding
    no.
    ¶64 Article V, section 1 of the Utah Constitution and the
    political question doctrine both focus on the proper roles of each
    branch of government and aim to curtail interference of one
    branch in matters controlled by the others. See Skokos, 
    900 P.2d at 541
    . Indeed, we have referred to article V, section 1 as the
    ―Separation of Powers Clause of the Utah Constitution.‖ Friends of
    Great Salt Lake v. Utah Dep’t of Nat. Res., 
    2017 UT 15
    , ¶ 16,

    Similarly, the political question doctrine is ―a tool for maintenance
    of governmental order,‖ Baker, 
    369 U.S. at 215
    , that is ―rooted in
    the United States Constitution‘s separation-of-powers premise.‖
    Skokos, 
    900 P.2d at 541
    . It ―prevents judicial interference in matters
    wholly within the control and discretion of other branches of
    government.‖ 
    Id.
     The United States Supreme Court has identified
    a political question issue, in part, as involving
    a textually demonstrable constitutional commitment
    of the issue to a coordinate political department; or a
    lack of judicially discoverable and manageable
    standards for resolving it; or the impossibility of
    deciding without an initial policy determination of a
    kind clearly for nonjudicial discretion; or the
    impossibility of a court‘s undertaking independent
    resolution without expressing lack of the respect due
    coordinate branches of government . . . .
    Baker, 
    369 U.S. at 217

    ¶65 Utah courts‘ adjudication of sex-change petitions
    neither involves a nonjusticiable political question nor violates
    article V, section 1 of the Utah Constitution. Our constitution
    grants the district courts, as general jurisdiction courts, the
    authority to adjudicate matters that affect a citizen‘s legal rights.
    See UTAH CONST. art. VIII, §§ 1, 5.
    ¶66 In adjudicating sex-change petitions—requests for a
    change to one‘s legal status or identification—district courts
    exercise one of the basic tenets of their judicial role: their
    common-law authority. That is because, as we explain above,
    supra ¶ 50, the legislature intertwined sex-change petitions with
    name-change petitions and planted the ―sex-change‖ adjudication
    firmly in the name-change common-law adjudication‘s ―old soil.‖

    818 P.2d 8

    governing a district court‘s handling‖ of common-law matters,

    Cetacean Soc’y, 
    478 U.S. 221
    , 230 (1986). But that does not mean we
    or our district courts can simply ―shirk‖ those roles by
    announcing them nonjusticiable. 
    Id.
     History provides us with a
    relevant example: In 1889, our territorial supreme court
    adjudicated a naturalization petition of a ―native of the Hawaiian
    Islands.‖ In re Kanaka Nian, 
    21 P. 993
    , 993 (Utah 1889). In that
    procedure—which, similar to the one we adjudicate today, asked
    for a change of legal status—our predecessor court did not shy
    away from adjudicating the question whether ―the native
    inhabitants of the Hawaiian islands belong to the white or African
    race,‖ and engaged in the science of the time on the matter. 
    Id.
    While we do not endorse that analysis, we see it as an example of
    our long-standing commitment to effectuate the judicial task laid
    upon us by the legislature, despite the sensitivity of the issues
    involved.
    ¶68 The money line here is this: The exercise of common-
    law authority, when not abrogated by statute, neither runs afoul
    of the political question doctrine nor violates the separation-of-

    powers.‖ Norton, 818 P.2d at 17; see also Cruz v. Wright,

    powers requirements of article V, section 1. A contrary conclusion
    would mean a doomsday for our historic judicial function. In the
    background looms our presumption of constitutionality, which
    reinforces our holding here. We ―apply a presumption of validity
    [to a challenged statute] so long as there is a reasonable basis
    upon which both provisions of the statute and the mandate of the
    constitution may be reconciled.‖ Richards v. Cox, 
    2019 UT 57
    , ¶ 12,
    
    450 P.3d 1074
     (alteration in original) (citation omitted). A statute
    violates the constitution only when it ―clearly violates a
    constitutional provision.‖ Vega, 
    2019 UT 35
    , ¶ 12 (emphasis
    added). Accordingly, ―a party seeking to challenge the
    constitutionality of a law‖ faces a heavy burden and must
    ―provide a sufficient basis‖ for such challenge, and not merely ―a
    ‗murky‘ basis for setting it aside.‖ South Salt Lake City v. Maese,
    
    2019 UT 58
    , ¶ 96, 
    450 P.3d 1092
     (Lee, A.C.J., concurring). In this
    case, no party—other than the district court, sua sponte—has
    argued that Utah Code section 26-2-11 is unconstitutional, let
    alone met their burden to set it aside. And, with all due respect to
    the district court, its conclusory decision did not do that either.
    Regardless, pursuant to rule 25A(b) of the Rules of Appellate
    Procedure—which grants the Attorney General permissive
    intervention ―[a]ny time a party challenges the constitutionality of
    a statute‖—this court called for the views of the Attorney General
    in its August 23, 2019 supplemental briefing order. As noted
    above, the Attorney General declined to answer whether the
    statute was unconstitutional and instead cited the presumption of
    constitutionality existing when no parties have actually made
    such a challenge. See supra ¶ 62.
    ¶69 The dissent disagrees. We discern three arguments it
    makes to support its contrary position: 28 (1) sex-change petitions
    are akin to ―issuing or amending a government record, license, or
    permit,‖ see infra ¶ 154, which are executive functions; (2)
    __________________________________________________________
    28   The dissent does not explicitly challenge the
    constitutionality of section 26-2-11, yet its arguments are rooted in
    our constitutional principles of separation of powers and the
    scope of ―judicial power.‖ Perhaps the dissent knows that its
    propositions, properly framed, would not withstand our
    presumption of constitutionality. See supra ¶ 68. Regardless,
    because the effect of accepting these arguments is to conclude that
    section 26-2-11 is unconstitutional, we address them as such.
    33
    IN RE SEX CHANGE
    Opinion of the Court
    adjudicating sex-change petitions means we undo all limits on our
    judicial role, infra ¶¶ 188–90; and (3) this court runs afoul of the
    nondelegation doctrine by engaging in ―an act of judicial
    legislation.‖ See infra ¶ 305.
    ¶70 We can easily dispose of these arguments. All are
    premised on assumptions we rebutted above. As for the first
    argument, the dissent casts approvals of ―sex change‖ as
    ―licensing‖ because the ―law opts for that form of regulation.‖
    Infra ¶ 154 n.73 (quoting Carter v. Lehi City, 
    2012 UT 2
    , ¶ 47, 
    269 P.3d 141
    ). Consequently, it argues that we are without power to
    address such issues because we are ―foreclosed from exercising
    executive power.‖ Infra ¶ 154. But we are not seeking to order
    changes to an individual‘s permit or license. We are operating
    under the substantive grant of power to adjudicate changes to
    legal status or identification and filling a gap which the legislature
    has implicitly asked us to address. See supra ¶¶ 47–48. And
    nowhere do we find evidence that the ―law opts for that form of
    regulation‖ in changes to an individual‘s legal status or
    identification. The dissent offers no explanation for its collapsing
    of the terms ―legal status or identification‖ and ―issu[ing] or
    amend[ing] any government record, license, or permit,‖ see infra
    ¶ 189, but we find that areas of the law traditionally regulated by
    the executive‘s permitting and licensing function are
    distinguishable from matters involving legal status or
    identification.29 Further, the dissent‘s argument is based on its
    __________________________________________________________
    29 The analysis in Carter, cited by the dissent at infra ¶ 154 n.73,
    directs readers to Utah Code section 58-1-103 (2012), which
    created the Utah Division of Occupational and Professional
    Licensing within the executive‘s Department of Commerce. 
    2012 UT 2
    , ¶ 47 n.35. This area of the law does not contemplate changes
    to an individual‘s legal status or identification but rather regulates
    occupations and professions in order to ―protect[] the health and
    safety of the public.‖ See UTAH CODE § 58-1-301(5). Other areas of
    the law that ―opt[] for that form of regulation‖ include driver
    licenses and concealed firearm permits, both of which are
    regulated by the Utah Department of Public Safety, presumably
    for public safety purposes. See UTAH CODE §§ 53-3-103, 53-5-703.
    And the laws concerning construction and fire codes, see id.
    §§ 15A-1-201 to 210; id. §§ 15A-1-401 to 403, also ―opt[] for‖
    permitting and licensing regulation in order to ―safeguard[] life

    assertion ―that the statute was plowing no new ground, and thus
    that the contemplated order for an amendment to a birth
    certificate is to be based on the same type of sex designation made
    at birth.‖ Infra ¶ 141. But that assumption, as we explain below,
    infra ¶¶ 75–81, is wrong. Without such standard, the theory the
    dissent proffers is irrelevant.
    ¶71 The second argument is likewise premised on faulty
    assumptions. It overlooks the historical substantive power of the
    courts to adjudicate name changes and thus, by analogy, sex
    changes. Infra ¶ 189. And further, our decision today bears little
    threat of opening the jurisdictional floodgate to all non-
    adversarial matters because it is inherently limited by the
    language of the statute before us and by the analogy we draw
    between name and sex changes. See supra ¶¶ 40–43.
    ¶72 The third argument also holds no water. The dissent
    suggests that this court runs afoul of the nondelegation doctrine
    by engaging in ―an act of judicial legislation‖ by seeking to fill any
    gap left open by the legislature. Infra ¶ 305. Such is not the case
    here. As we explained above, supra ¶¶ 46–47, Utah Code section
    26-2-11 is a statute enacted specifically in aid of our common-law
    authority, and the ―core, governing principle‖ in adjudicating sex-
    change petitions has already been identified through the common
    law of name-change petitions. Thus, because name-change and
    sex-change petitions are analogous in function, we are not
    overstepping our judicial role when we apply the common law of
    name-change petitions as the ―core governing principle‖ in
    adjudicating sex-change petitions.
    ¶73 We thus conclude that Utah Code section 26-2-11 and
    the district courts‘ adjudication of sex-change petitions violate
    neither the political question doctrine nor any separation-of-
    powers principles. Hence, Utah courts do not violate the Utah
    Constitution when adjudicating sex-change petitions.
    and property.‖ Id. § 15A-1-403(1)(a)(ii). Certainly, legal status or
    identification matters may include public safety functions, but
    while licensing and permitting appear to be based primarily on
    public safety purposes, such is not the primary function of legal
    status or identification. See supra ¶ 35.

    IN RE SEX CHANGE
    Opinion of the Court
    IV. THE TEST FOR SEX-CHANGE PETITIONS
    ¶74 Although Utah courts have the authority to adjudicate
    sex-change petitions, we have not, until now, had the opportunity
    to review a district court‘s decision to grant or deny one. That
    means that we have never articulated a test by which Utah courts
    should decide sex-change petitions. We take that step today. To
    do so, we borrow from our common-law jurisprudence about
    name-change petitions and adapt it to fit sex-change petitions. We
    conclude that, as a general rule, sex-change petitions should be
    granted if (1) they are not ―sought for a wrongful or fraudulent
    purpose,‖ In re Porter, 
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
     (citation
    omitted), and (2) they are supported by objective evidence of a sex
    change, which includes, at minimum, evidence of appropriate
    clinical care or treatment for gender transitioning or change by a
    licensed medical professional. But before we detail how we reach
    this test and explain it, we respond to the dissent‘s suggested test.
    A. Sex-Change Petitions Are Not Limited to Mistake or Sex-
    Reassignment Surgery
    ¶75 In refuting the dissent‘s proffered test, we first explain
    how the dissent erroneously reads a substantive standard for ―sex
    change‖ into a simple, non-substantive statute. Then, for the sake
    of completeness, we show how its proposed standard is
    unworkable and cannot reflect the intent of the legislature.
    ¶76 The dissent takes a wrong turn at the outset of its
    analytical expedition. It reads into the language of the statute a
    substantive standard for approving a sex change.30 Focusing on
    the word ―sex,‖ it posits that ―[t]he term [‗sex‘], in this context, is
    plain‖ and ―sex‖ in this context ―refer[s] to biological sex.‖ Infra
    __________________________________________________________
    30 The dissent initially concedes that ―[t]he statute itself does
    not expressly articulate a ‗substantive standard,‘‖ infra ¶ 141,
    presumably to set up its jurisdictional argument that we are
    engaged in a ―novel‖ ―‗gap-filling‘ role,‖ infra ¶ 245, by simply
    giving effect to the statute and voice to the common law.
    Nonetheless, it implies throughout its argument on the merits that
    ―sex‖—rather, ―biological sex‖—acts as a standard intended by
    the legislature. See, e.g., infra ¶¶ 204-06. Indeed, the statement that
    we are attempting to ―establish a new concept of gender identity,‖
    infra ¶ 200 (emphasis added), implies that the ―new concept‖
    replaces an existing one.
    36
    Cite as: 
    2021 UT 13
    Opinion of the Court
    ¶ 217. From there, the dissent reasons that a person can only
    change their ―biological sex,‖ as indicated on the birth certificate,
    by showing that their initial sex designation was essentially a
    mistake or, possibly, that they have undergone sex-reassignment
    surgery. Infra ¶ 223.
    ¶77 As we have repeatedly noted, the statute does not
    contain an express substantive standard; rather, it functions as an
    aid to the court in the exercise of its common-law authority.31
    Utah Code section 26-2-11(1) provides that when a person ―has a
    name change or sex change approved by an order of a Utah
    district court or a court of competent jurisdiction of another state
    or a province of Canada,‖ that person may file with the state
    registrar a certified copy of the order, along with a standard
    application form. Upon receipt of a complete application, order,
    and fee, the registrar ―shall . . . register it and note the fact of the
    amendment‖ on the original birth certificate. UTAH CODE § 26-2-
    11(2)(a). The amendment then ―become[s] a part of the original
    certificate.‖ Id. § 26-2-11(2)(b). So, the statute acknowledges that
    Utah district courts have authority to approve a name change or
    sex change. And it tells the state registrar what it must do with
    such an order. That is literally all the statute says and does.
    ¶78 Nothing in this text suggests a legislative intent that a
    court approve a sex change only if the petitioner proves their
    initial sex designation was a mistake or they have completed sex-
    reassignment surgery. In fact, the plain language demonstrates a
    legislative intent to omit such a standard. If a petitioner submits a
    complete application, the state registrar ―shall‖ register a sex
    change ―approved by an order of a Utah district court or a court of
    competent jurisdiction of another state or a province of Canada.‖
    Clearly, the legislature cannot control the standard for ―sex‖ or
    ―sex change‖ applied by any other jurisdiction. 32 Yet the state
    __________________________________________________________
    31  And as we have repeatedly pointed out, supra ¶¶ 47, 50-51,
    54, the legislature, in deciding that a person may seek to change
    the sex designation on their birth certificate, intended to omit a
    substantive standard from the statute, and in doing so expected
    the courts to fill the gap. Otherwise, we would be left with a
    meaningless statute.
    32 Canadian courts have similarly been ordering changes to
    birth certificates to reflect an individual‘s gender identity and, in
    the process, have rejected the narrow view of ―sex change‖
    (continued . . .)

    registrar must respect it.33 Consequently, and with the greatest of
    respect to the dissent, there is nothing in Utah Code section 26-2-
    11 that suggests that the legislature intended Utah courts to apply
    a very narrow standard for ―sex change‖ while simultaneously
    offered by the dissent. See F.C. v. Alberta (Vital Statistics), 2014
    ABQB 237, paras. 4–7, 65 (Can.); XY v. Ontario (Minister of
    Government and Consumer Services), 2012 HRTO 726, [2012]
    O.H.R.T.D. No. 715 (Can. Ont. Human Rights Trib.).
    33  The dissent responds that ―Utah law is the substantive law
    that governs the content of Utah vital records‖ when foreign
    courts adjudicate a sex change to a Utah birth certificate because
    ―[n]othing in the statute . . . indicates that the legislature was
    conferring power on the courts of other states to impose their
    substantive law‖ on the content of a Utah birth certificate. Infra
    ¶ 288. This interpretation is erroneous for at least three reasons.
    First, the statute‘s plain language unambiguously extends respect
    and reciprocity to court orders of sister jurisdictions. Otherwise, if
    the dissent were correct, a foreign court would be required to
    apply the dissent‘s non-articulated standard for sex change
    (which the dissent argues it could not do anyway, since it claims
    the issue is non-justiciable). Second, the dissent does not explain
    how the state registrar would know whether to accept the foreign
    court order. The statute provides the state registrar with no
    discretion to evaluate a foreign court‘s application of Utah law.
    And third, the legislature knew how to specify elsewhere within
    the Vital Statistics Act when the state registrar should limit its
    reciprocity to Utah law. See UTAH CODE § 26-2-28(1) (requiring the
    registration of any person ―adopted under the laws of this state‖);
    id. § 26-2-17(5) (providing for the immediate transportation
    outside of the death registration district of any dead body or part
    thereof when it ―has been donated under the Revised Uniform
    Anatomical Gift Act or similar laws of another state‖). It did not
    do so in section 26-2-11.
    In short, we point to the concurrence‘s observation that ―the
    legislature was not so concerned with setting a substantive
    standard by its use of the terms ‗name change‘ and ‗sex change‘ as
    it was with identifying the kinds of birth certificate amendments
    subject to the statute.‖ Infra ¶ 123.

    Opinion of the Court
    extending the      broadest    possible   reciprocity   to   foreign
    jurisdictions.34
    ¶79 The original statutory text further solidifies our view
    that the legislature intentionally omitted from the statute a
    standard for ―sex change.‖ That text provided that ―[w]henever a
    person born in this state has their name and/or sex change
    approved by an order of a court [of any State or U.S. Territory], a
    certified copy of the court order may be filed with the office of the
    state registrar upon an application form provided by such
    registrar.‖35 
    1975 Utah Laws 222
     (emphasis added). The statute
    then went on to direct the board of health to ―establish fees to be
    received for preparation of . . . amended birth certificates
    provided in section 26-15-16.5, [the original statutory provision].‖
    
    Id.
     Combining name change and sex change together like this
    (―name and/or sex change‖) and the reference to amended birth
    certificates reinforce the idea that ―sex‖ refers to the designation
    on the birth certificate; it does not speak to the standard
    __________________________________________________________
    34 The dissent warns that our decision here is a ―big deal‖ with
    ―sweeping effects on our society.‖ Infra ¶ 236. We disagree—Utah
    courts have been deciding this issue for many years without our
    guidance. See infra ¶ 103 n.53. In fact, our decision today gives
    more certainty to a process that, thus far, has not upended the
    fabric of society. All we can say for sure is that this issue is
    certainly a ―big deal‖ for Mr. Childers-Gray and Ms. Rice. Their
    lives have been put on hold simply by chance—the district court
    in which they submitted their petitions just happened to
    misinterpret the statute, denying the petitioners a path to take
    advantage of section 26-2-11 in the way petitioners in other
    districts have been able to do. Today we put an end to their wait.
    35  As we explain above, supra ¶ 2 n.3, the current statute has
    undergone some minor linguistic changes. Specifically relevant
    here, the current statute reads: ―[w]hen a person born in this state
    has a name change or sex change approved . . . .‖ UTAH CODE § 26-2-
    11 (emphasis added). No party has argued that such changes
    matter to our interpretation of the statute. However, the dissent
    engages with the meanings of ―sex‖ and a ―‗change‘ to birth
    certificate ‗sex‘ designation‖ in 1975, infra ¶¶ 213-19, and we find
    the original legislative use of the ―and/or‖ phrase particularly
    illustrative of the incongruity of the dissent‘s position, and we
    highlight it accordingly.
    39
    IN RE SEX CHANGE
    Opinion of the Court
    underlying whether the court should or should not grant the
    order.
    ¶80 And finally, the legislature has explicitly shown that it
    can and does articulate standards in the name- and sex-change
    context, even if it did not do so here. In Utah Code section 77-41-
    105(8), the legislature provided a clear substantive limitation for
    registered sex and kidnapping offenders petitioning to change
    their names. This limitation prohibits a Utah court from granting a
    name change unless it finds that ―the name change is not contrary
    to the interests of the public.‖ UTAH CODE § 77-41-105(8)(a).
    ¶81 In sum, the plain language of the statute compels the
    conclusion that the legislature deliberately omitted from the
    statute any standard for approving a sex change. In so doing, it
    expected the judiciary to exercise its common-law authority to
    create such a standard. And we do so today, considering all
    indicia of legislative intent and persuasive authority that we can
    muster. See infra Parts IV(B) & (C).
    ¶82 Further, the dissent‘s fundamental misreading of the
    statutory language leads it to engage with the term ―sex‖ in a
    manner that not only does not fit the statutory language, but
    plainly ignores it. See State v. Rushton, 
    2017 UT 21
    , ¶ 11, 
    395 P.3d 92
     (―[W]ords or phrases may appear unambiguous when read in
    isolation, but become ambiguous when read in context. This is
    why ‗we 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[,] . . . avoid[ing] any interpretation
    which renders parts or words in a statute inoperative or
    superfluous in order to give effect to every word in the statute.‘‖
    (alterations in original) (citation omitted)).
    ¶83 And even if the dissent were correct in its reading, it
    would not satisfactorily answer the question we address here
    because we do not agree with the dissent‘s understanding of the
    term ―sex.‖ Even if the legislature intended for the phrase ―sex‖ to
    be a standard (and it did not), the dissent‘s definition of biological
    sex does not necessarily exclude sex that has been changed in
    conformance with an individual‘s gender transition.
    ¶84 It is remarkable that a simple, three-letter word can
    inspire such widespread, passionate debate. We are not tasked
    with charting the course for the evolution of language itself, but
    we are obligated to interpret a word or term as it was intended by
    the legislature at the time of drafting. Here, that does not
    necessarily mean determining ―whether the term ‗sex‘ as used in a
    40
    Cite as: 
    2021 UT 13
    Opinion of the Court
    1975 statute governing the terms of a birth certificate can be
    understood as a reference to the concept of ‗gender identity‘ that
    has evolved in recent years.‖ Infra ¶ 213. The inquiry is rather
    much simpler and does not require a hindsight view of the
    evolving concept of gender identity—we should be asking,
    merely, what the legislature meant by ―sex‖ in the birth certificate
    context.
    ¶85 No matter which side of the ―culture war,‖ infra ¶ 212,
    one occupies, it appears generally understood that, in most
    instances, ―sex‖ as designated at birth is based on a medical
    observation of genitalia and physical characteristics. See supra ¶ 4
    n.5. But even if we were to concede that ―sex‖ means ―biological
    sex,‖ the concept very likely extends beyond what a cursory
    physical examination of an infant can reveal. We allude to the
    dissent‘s presentation of dictionary definitions of ―sex‖ existing at
    the time of Utah Code section 26-2-11‘s enactment, see infra ¶ 214
    n.100, in conceding that ―sex‖ was primarily defined in terms of
    ―structural and functional differences‖ between males and
    females (including reproductive functions).
    ¶86 However, we are not convinced that a standard of
    ―biological sex‖ would preclude the adopted sex of transgender
    individuals. It is worth noting that while the dictionary
    definitions of ―sex‖ provided by the dissent have some focus on
    physiological differences between males and females, many
    definitions focus also on ―psychological,‖ ―behavior[al]‖, or
    ―character‖ differences, infra ¶ 214 n.100, which are not
    necessarily tied exclusively to physiology or observable
    characteristics at birth. At the very least, ―biological sex‖ itself is
    ambiguous and may mean more than the sex designated by
    examination at birth.
    ¶87 The dissent‘s conception of ―biological sex‖ in the birth
    certificate context arises from its understanding that, typically, ―a
    person‘s sex is determined at birth by an anatomical examination
    by the birth attendant.‖ Infra ¶ 216 n.102 (quoting In re Ladrach,
    
    513 N.E.2d 828
    , 832 (Stark Cnty. Ohio Prob. Ct. 1987)).36 But the
    __________________________________________________________
    36Of course, as the dissent points out, some infants are born
    with ambiguous genitalia, which require more thorough
    examinations for sex designation, perhaps beyond external
    physical characteristics. See infra ¶ 216 n.102. However, such
    occurrences requiring examination by medical specialists are rare.
    (continued . . .)
    41
    IN RE SEX CHANGE
    Opinion of the Court
    ―anatomical examination‖ done at birth contemplates only the
    observable genitalia, which is limited at the neonatal stage. Of
    course, secondary sex characteristics, such as those that may be
    altered by hormone therapy, do not begin to develop until later in
    life. And certainly, ―a baby has no capacity for expression of
    gender identity.‖ Infra ¶ 216. So even if we look only to the
    observable physiological indicators of sex to guide us, many
    transgender individuals would still lie within the dissent‘s
    definition, given that they may later undergo sex-reassignment
    surgery, hormone therapy, or other treatment to bring their
    physical appearances into alignment with their gender
    identities.37 See, e.g., Saru Matambanadzo, Engendering Sex: Birth
    Certificates, Biology and the Body in Anglo American Law, 12
    CARDOZO J.L. & GENDER 213, 219 (2005) (noting that surgical
    procedures often serve to ―bring [an individual‘s] ‗biological sex‘
    into line with their gender identity‖). It does not seem that the
    dissent would disagree with this logic. See infra ¶ 223 (stating that
    ―a basis for a ‗change‘‖ in an individual‘s sex designation ―might
    be met where a person can demonstrate that the biological
    indicators of sex have been altered‖).
    See, e.g., Elizabeth Reilly, Radical Tweak—Relocating the Power to
    Assign Sex, 12 CARDOZO J.L. & GENDER 297, 299 (2005) (providing
    an estimate that intersex births occur in 1.7% of live births (citing
    ANNE FAUSTO-STERLING, SEXING THE BODY: GENDER POLITICS AND
    THE CONSTRUCTION OF SEXUALITY 92–95 (2000)); Alice Domurat

    in the Treatment of Intersexuality, 28 HASTINGS CTR. REP. 24, 26
    (1998) (noting that the frequency in which ―sex is doubtful
    because of the external genitalia‖ is ―roughly 1 in 1,500 live
    births‖). Given the rarity of such births, and with all due respect
    to those individuals, we find it is unnecessary to contemplate
    these cases in our analysis. It appears the dissent may agree. See
    infra ¶ 226 (stating that the ―‗sex‘ designation on a birth certificate
    is an objective determination based on observation of physical
    characteristics‖ (emphasis added)).
    37   For example, hormone therapy ―is an effective step for
    enhancing feminine or masculine secondary sex characteristics
    (e.g., voice, facial hair, breast tissue, muscle mass).‖ Dean Spade,
    Documenting Gender, 59 HASTINGS. L.J. 731, 755 (2008).

    Opinion of the Court
    ¶88 But if the dissent defines the term ―biological sex‖ as
    encompassing observable sex characteristics and genetically
    controlled sex chromosomes, the statute would be rendered
    nonsensical. In the birth certificate context, sex is generally
    determined by an external ―anatomical examination,‖ not by an
    examination of the individual‘s chromosomal makeup.38 And the
    legislature could not have intended to include consideration of
    sex chromosomes in its conception of ―sex‖ in a statute regarding
    name and sex changes because sex chromosomes are immutable
    and no therapy, treatment, or procedure exist to alter them (at
    least not currently, and certainly not in 1975). See, e.g., Julie A.
    Greenberg, Defining Male and Female: Intersexuality and the Collision
    Between Law and Biology, 41 ARIZ. L. REV. 265, 294 (1999) (―[T]he
    only sex indicators that are truly fixed are chromosomes . . . .‖).
    ¶89 Additionally, if we were to view ―biological sex‖ as
    including the immutable genetic makeup of an individual, we
    would unearth another absurdity. This standard would leave
    open only the possibilities that a sex change could be approved
    because of a ―discovery of a mistake in the biological sex
    designation made at the time of a child‘s birth, or a showing that
    the biological features of an intersex person have developed
    differently than expected at birth.‖39 Infra ¶ 223. But if ―sex‖ on a

    38 Except in rare cases involving ambiguous genitalia. See supra
    ¶ 87 n.36.
    We also note that chromosomal examinations have their own
    limitations, as evidenced by the story of world-class hurdler
    Maria Patiño. Ms. Patiño was banned from competing in the 1985
    World University Games after a sex chromatin test revealed she
    had the chromosomal makeup of a male (XY). Julie A. Greenberg,
    Defining Male and Female: Intersexuality and the Collision Between
    Law and Biology, 41 ARIZ. L. REV. 265, 273 (1999). Ms. Patiño was
    unaware that she had a condition that caused her ―external
    morphologic sex, phenotype, and self-identification‖ as a female
    to conflict with her chromosomal make-up as a male. Id.
    39 We do not accuse the dissent of making or relying on the
    argument that ―biological sex‖ includes genetic indicators of sex.
    Notably, the dissent recognizes that its ―biological sex‖ standard
    ―also might be met where a person can demonstrate that the
    biological indicators of sex have been altered, as by sex-
    reassignment surgery.‖ Infra ¶ 223. Rather, we use the dissent‘s
    (continued . . .)
    43
    IN RE SEX CHANGE
    Opinion of the Court
    birth certificate indicates a purely biological trait and not an
    identifier of legal status, then why does one need a court order to
    change it?40 And, again, why does the statute not differentiate
    between ―name change‖ and ―sex change‖ if the former is a legal
    classification and the latter is biological?
    ¶90 We have said in the past, including in an opinion
    penned by the author of today‘s dissent, that we could not
    possibly attribute ―absurdity‖ to our legislature because such
    ―construction‖ is ―so far beyond the realm of the conceivable.‖
    Graves v. N.E. Servs., Inc., 
    2015 UT 28
    , ¶ 71 n.10, 
    345 P.3d 619
    . And
    in this case, a construction that ―sex‖ means ―biological sex‖
    including genetics (one‘s chromosomal makeup) would be ―so
    language to highlight why any definition of ―biological sex‖
    would ultimately fail in this context.
    40  The Utah Vital Statistics Act generally requires health care
    professionals to directly file certificates based on purely medical
    observations. See, e.g., UTAH CODE § 26-2-5(3) (requiring a
    ―birthing facility administrator or his designee‖ or the ―attending
    physician or nurse midwife‖ to fill out, sign, and file a birth
    certificate with ―medical information‖); id. § 26-2-14 (requiring an
    ―institution administrator or his designated representative‖ or a
    physician to ―complete, sign, and file [a] fetal death certificate‖);
    id. § 26-2-13 (requiring a ―funeral service director,‖ or in some
    cases a ―health care professional,‖ to complete and file a certificate
    of death). By contrast, the Act requires a court order in only three
    circumstances: (1) to provide a birth certificate for an adopted
    foreign child, id. § 26-2-28; (2) to ―establish[] the fact, time, and
    place of a birth or death that is not registered,‖ id. § 26-2-15; and
    (3) to approve a ―name change or sex change‖ amendment to a
    birth certificate. Id. § 26-2-11. These situations all deal with the
    establishment of an individual‘s legal status or identification,
    independent from any medical observation.
    Again, the dissent argues that ―sex‖ can only be changed due
    to ―discovery of a mistake in the biological sex designation made
    at the time of a child‘s birth, or a showing that the biological
    features of an intersex person have developed differently than
    expected at birth.‖ Infra ¶ 223. Since these two conditions are both
    fundamentally medical observations, we can assume that, if the
    legislature had intended this result, it would have simply allowed
    a health care professional to complete and file the amendment.

    ).
    ¶91 So, to put it simply, biological sex, as it is understood in
    the birth certificate context, may transform according to how a
    transgender individual chooses to respond to their gender
    dysphoria. But we take this opportunity to caution against relying
    even on the term ―biological sex‖ as defined by observable
    external attributes. Transitioning from male to female or female to
    male is a process, not a switch. We must avoid relying on terms
    that may lead us toward setting a threshold for completion of a
    transition, because that is a line we are not equipped to draw.
    Even relying on the term ―sex-reassignment surgery,‖ infra
    ¶¶ 219, 223, 240, as a threshold would be unhelpful because it is a
    vague standard. Transgender individuals have an array of
    surgical options by which they can effectuate their transition, if
    that is indeed the route they wish to take. These options include
    facial reconstruction, orchiectomy (removal of gonads),
    vaginoplasty,     mammoplasty,         mastectomy,      hysterectomy,
    vaginectomy, phalloplasty, see In re Heilig,

    appears to be little inter- and intra-jurisdictional consensus on the
    exact definition of ―sex-reassignment surgery.‖ Some jurisdictions
    use the term as an umbrella term for all gender-affirming surgical
    procedures. See, e.g., Fields v. Smith,

    , 552 (7th Cir.

    Opinion of the Court
    to procedures altering the primary sex organs. See, e.g., Campbell v.

    reassignment surgery‖ to refer to ―surgeries that replace an
    individual‘s existing genitals with approximations of those of the
    opposite sex,‖ in a case analyzing an Eighth Amendment claim).
    Some jurisdictions do not even use the term. See, e.g., Hare v. Minn.
    Dept. of Hum. Servs., 666 N.W.2d. 427, 431–32 (Minn. Ct. App.
    2003) (interpreting the term ―gender reassignment services‖ as an
    umbrella term for all ―treatment necessary to address gender
    dysphoria‖); Good v. Iowa Dept. of Hum. Servs., 
    924 N.W.2d 853
    ,
    856–57 (Iowa 2019) (interpreting the term ―gender-affirming
    surgery‖ to refer specifically to procedures altering an
    individual‘s ―sex characteristics‖). All this is to say we are judges,
    not medical professionals, which is why our standard relies on
    licensed medical professionals to establish that an individual
    petitioner has received what the medical professional deems to be
    appropriate treatment.41 We also note that while we take the time
    to respond to the dissent‘s engagement with the definition of
    ―sex,‖ we emphasize again that ―sex‖ was not intended to
    designate a standard in this statute.
    ¶92 But despite all the dissent‘s guesswork about the
    legislature‘s intent that ―sex‖ means ―biological sex,‖ it matters
    not because the legislature did not use those words. And ―[j]udges
    are not free to overlook plain statutory commands on the strength
    of nothing more than suppositions about intentions or guesswork
    __________________________________________________________
    41  But we do understand that health care treatment is
    expensive, and not all individuals are capable of affording or
    accessing the kind of treatment that would effectively change an
    individual‘s external sex characteristics. Further, the cost of sex-
    reassignment surgery is ―much higher‖ for transgender men than
    women. Heilig, 816 A.2d at 78. ―One commentator has asserted
    that a male-to-female operation costs an average of $37,000,
    whereas the average female-to-male operation costs $77,000.‖ Id.

    Picket Fence: The Need for Federal Legislation to Protect the Insurance
    Rights of Infertile Couples, 41 WASHBURN L.J. 191, 198 (2001)). Given
    these high costs and disparate impacts on transgender men versus
    transgender women, we can imagine that any standard for ―sex
    change‖ that relies on surgical intervention would be vulnerable
    to equal protection challenges.

    we exercise our ―judicial power‖ to effect the intent of the
    legislature by fulfilling that statutory gap with our established
    common law, which is precisely what the statute, properly read,
    calls for.
    B. Not Sought for a Wrongful or Fraudulent Purpose
    ¶94 The first prong in the test we articulate adopts the
    common-law jurisprudence regarding name-change petitions.
    Generally, sex-change petitions—just like name-change
    petitions—should be granted if they are not ―sought for a
    wrongful or fraudulent purpose.‖ See In re Porter, 
    2001 UT 70
    , ¶ 8.
    We adopt this prong because name changes and sex changes—
    along with the policy reasons for allowing or disallowing them—
    are similar. We detail these similarities below before we outline
    the test we have historically applied to adjudicate name-change
    petitions.
    ¶95 A name change and a sex change are both changes to
    one‘s personal legal status or identification. Supra Parts I(B) and
    (C). Like with a legal name, a person is assigned a sex designation
    at birth, and it appears on their birth certificate. Like with a legal
    name, a person, later in life, may not identify themselves with
    their birth sex designation.
    ¶96 The policies underlying the authority of courts to
    approve name changes apply as forcefully to sex changes. The aim
    of facilitating such changes is to promote clarity and avoid
    confusion. See In re Porter, 
    2001 UT 70
    , ¶ 11. A ―legal name change
    . . . actually prevent[s] the daily confusion and public
    confrontations which presently plague [a person‘s] dealings with
    the public‖ when their chosen name is different than the one that
    appears on their government identification. In re Harris, 
    707 A.2d at 228
    .
    47
    IN RE SEX CHANGE
    Opinion of the Court
    ¶97 The same is true for sex changes. A person‘s sex
    designation can govern various interactions with the government
    and with the public. Government agencies use sex designation ―to
    validate a transgender person‘s identity when being used to
    access social benefits, services, or other forms of identification.‖

    LGBTQ Jurisprudence to Make the Argument for a Transgender
    Person’s Constitutional Right to Amend Identity Documents, 22
    CUNY L. REV. 78, 97 (2019). An Alaska trial court has described
    the problem succinctly in the context of driver licenses:
    By not allowing transgendered individuals to change
    their sex designation, their license will inaccurately
    describe the discernable appearance of the license
    holder by not reflecting the holder‘s lived gender
    expression of identity. Thus, when such individuals
    furnish their license to third-persons for purposes of
    identification, the third-person is likely to conclude
    that the furnisher is not the person described on the
    license.

    2012 WL 2685183
    , at *7 (Alaska Super. Ct. Mar.
    12, 2012).
    ¶98 Ms. Rice‘s own experience supports this account. In her
    sex-change petition, she stated that, as a transgender woman
    whose birth certificate designates her sex as ―male,‖ she is
    ―subject to invasive and embarrassing scrutiny, including pat-
    downs, because her documentation doesn‘t match who [she is].‖
    Matching her identification documentation with her identity
    would significantly reduce any confusion and any misinformed
    treatment. Gone unchecked, such treatment can prevent
    transgender people from effectively participating in the public
    arena, including voting.42 See Julie Moreau, Strict ID Laws Could

    ¶99 Having established the similarities between name-
    change and sex-change petitions, we now turn to the test this
    court applies when adjudicating name-change petitions. This
    court‘s case law outlines ―very broad limits‖ to a person who
    wants to select ―the name by which he [or she] is known.‖ In re
    Porter, 
    2001 UT 70
    , ¶ 11; see In re Cruchelow, 
    926 P.2d 833
    , 834
    (Utah 1996). And we have held that name-change petitions
    ―should generally be granted.‖ In re Cruchelow, 926 P.2d at 834
    (citation omitted). This court has also held that one proper cause
    for a name-change petition is to conform a person‘s legal name to
    their identity. See In re Porter, 
    2001 UT 70
    , ¶ 11; see also In re
    Cruchelow, 926 P.2d at 834.
    ¶100 A court may deny a name-change petition only for a
    ―substantial reason‖ backed by ―factual support.‖ In re Cruchelow,
    926 P.2d at 834. We have explained that such reasons include a
    factually proven ―unworthy motive‖: fraud. In re Porter, 
    2001 UT 70
    ,
    ¶ 7 (citation omitted). On the other hand, a court may not deny a
    petition because of ―[u]nsupported generalizations and
    speculation,‖ including worries that the change could create
    confusion or misunderstanding,43 complicate government
    recordkeeping and notice requirements, cause substantial
    mischief, or create a chilling effect on potential future litigants. In
    re Porter,

    role as interpreters of statutes; it would tilt the scales
    of justice in favor of the strong or popular and neglect
    the promise that all persons are entitled to the benefit
    of the law‘s terms.
    Bostock, 140 S. Ct. at 1751.
    43 We repeat that the contrary is often true—confusion or
    misunderstanding is very likely to occur if an individual‘s legal
    sex designation does not match their external manifestations of
    gender identity. See supra ¶¶ 40, 96–98.

    IN RE SEX CHANGE
    Opinion of the Court
    ¶101 With these principles in mind, we have twice reversed
    denials of name-change petitions. We first did so in In re
    Cruchelow. There, we reversed a district court‘s denial of an
    inmate‘s request to change his name, while in custody, to reflect
    his newly adopted religious beliefs. In re Cruchelow, 926 P.2d at
    835. We held that ―unsupported generalizations and speculations‖
    about confusion in the prison‘s records and the Board of Pardons
    proceedings are not sufficient to deny such change. Id. We
    accordingly remanded the case to the district court for a hearing
    to consider any evidence supporting the court‘s concerns. Id.
    ¶102 Then, in In re Porter, we reversed a district court‘s
    decision to deny the appellant‘s petition to change his name to
    ―Santa Claus.‖ 
    2001 UT 70
    , ¶ 13. Porter argued that he needed the
    name change because he resembled the ―fictional character‖ and
    did numerous activities using that persona. Id. ¶¶ 6, 12. The
    district court found that, if allowed, the name change would
    ―create confusion‖ and ―misunderstanding‖ and ―could allow for
    substantial mischief,‖ and deter others from suing Porter. Id. ¶ 9.
    We reversed. We explained that there was no evidence to support
    the district court‘s concerns and, even if there were, these
    concerns were not enough to deny a name-change petition. Id.
    ¶¶ 11–13. We held that we do not sit as arbiters of the prudence of
    names chosen at will. And because Porter already held himself
    out as Santa Claus, ―[a]llowing him to legally change his name to
    reflect his practice of doing so is more likely to avoid greater
    confusion.‖ Id. ¶ 11. We remanded with instructions to enter the
    name-change order. Id. ¶ 13.
    ¶103 Because name and sex changes are analogous, we hold
    that—like a name-change petition—a sex-change petition ―should
    generally be granted unless sought for a wrongful or fraudulent
    purpose.‖ See id. ¶ 8 (quoting In re Cruchelow, 926 P.2d at 834).
    And, as long as a petitioner complies with the second prong of the
    test we announce today, infra ¶ 105, a court may deny a
    sex-change petition only for ―substantial reason‖ backed by
    ―factual support.‖44 In re Cruchelow, 926 P.2d at 834.45
    __________________________________________________________
    44 Below we note that the district court acted inappropriately
    when it made general, slippery-slope arguments about appellants‘
    petitions. See infra ¶¶ 117–18. The dissent raises similar arguments
    in stating that our ―decision will have far-reaching implications.‖

    primary known driver of differences in athletic performance

    leaves the dissent‘s ideas not only unsupported but rejected by
    judicial fact-finding and legal analysis.
    We note, importantly, that we do not intend to minimize
    feelings and emotions that individuals may have about
    transgender people in traditionally cisgender spaces, but there is
    no legal basis for us to ignore the ―needs, humanity, and decency

    IN RE SEX CHANGE
    Opinion of the Court
    C. Evidence of Appropriate Clinical Care or Treatment For Gender
    Transitioning or Change, Provided by a Licensed Medical Professional
    ¶104 Even though name and sex changes are similar in
    purpose, they are not identical. At birth, a person‘s name is given
    at the whim of a non-medical party (usually a parent). But a
    person‘s initial sex designation is inherently a medical evaluation
    made according to objective observation at birth, typically by a
    medical professional. See F.V. v. Barron, 
    286 F. Supp. 3d 1131
    , 1136
    (D. Idaho 2018) (―Sex determinations made at birth are most often
    based on the observation of external genitalia alone.‖).
    ¶105 We believe that, much like a sex designation made at
    birth, a change in sex designation should be accompanied by
    objective evidence. As a result, we hold that a petitioner must
    present, at the minimum, evidence of appropriate clinical care or
    treatment for gender transitioning or change, provided by a
    licensed medical professional.46 We do not require any specific
    if the rights of cisgender individuals are affected, those
    individuals may have their day in court once their issues are ripe.
    See supra ¶ 43 n.21.
    Ultimately, our decision today does not direct the State to
    allow transgender individuals to change their official
    documents—the legislature has already decided that in Utah
    Code section 26-2-11. It is our role to interpret that statute, and
    that is what we have done today. Nothing more.
    45 Clearly, the legislature may adopt a different rule for sex-
    change petitions. That definition would, of course, need to
    conform to constitutional standards that we need not address
    here.
    46  The dissent claims that our standard will allow for ―a birth
    certificate amendment upon a showing of any care or treatment.‖
    Infra ¶ 308. This claim is unfounded. The licensed medical
    professional that provides such evidence has professional ethical
    commitments, and the evidence of appropriate clinical care or
    treatment for gender transitioning or change provided by them
    must be in keeping with those commitments.
    And while we need not engage with the medical standard, we
    note that our review of a dozen Utah district court cases, see infra
    ¶ 111, shows that the relevant standard used by medical
    professionals is offered in the Diagnostic and Statistical Manual of
    (continued . . .)

    procedure or treatment. Instead, the licensed medical professional
    should provide that the appropriate clinical care or treatment
    conforms with the relevant medical standard of care for gender
    dysphoria.47
    ¶106 This standard is prudent based on several authorities: a
    Utah statute defining ―gender identity,‖ federal requirements for
    sex change, case law from other jurisdictions, and the decisions of
    Utah district courts.48
    Mental Disorders, Fifth Edition (DSM-5) (a standard endorsed by
    our legislature in another context, see infra ¶ 107 n.49). The fact-
    sheet regarding ―Gender Dysphoria‖ states that ―[f]or a person to
    be diagnosed with gender dysphoria, there must be a marked
    difference between the individual‘s expressed/experienced
    gender and the gender others would assign him or her, and it
    must continue for at least six months.‖ AM. PSYCHIATRIC ASS‘N,

    field‖ (emphasis added)).
    47 We do not address in this opinion the issue of non-binary
    sex designation because it was not raised by the parties, who each
    seek a binary sex designation change. We leave this question for
    an appropriate case.
    48 The dissent refers to our ―evolving‖ use of the term ―gender
    identity.‖ Infra ¶ 149. We do not argue that ―sex‖ means ―gender
    identity.‖ The ―sex‖ designation on a birth certificate is a datum of
    legal status. And consistent with many other state and federal
    authorities, see infra ¶ 107–11, our test allows a person to change
    (continued . . .)
    53
    IN RE SEX CHANGE
    Opinion of the Court
    ¶107 First, the Utah legislature has opined in another context
    about what evidence is sufficient to prove one‘s gender identity.
    The Utah Fair Housing Act addresses how one can show their
    gender identity:
    A person‘s gender identity can be shown by
    providing evidence, including, but not limited to,
    medical history, care or treatment of the gender
    identity, consistent and uniform assertion of the
    gender identity, or other evidence that the gender
    identity is sincerely held, part of a person‘s core
    identity, and not being asserted for an improper
    purpose.
    UTAH CODE § 57-21-2(16).49 We find this statutory test for proving
    one‘s gender identity suggests a legislative intent as to how one
    might prove why a change to the sex designation on their birth
    certificate is proper.50 Still, the test we articulate today is bound
    by the historical limitations of our non-adversarial adjudications,
    such as name-change petitions, to which we analogize. As
    explained above, our jurisprudence requires that a petitioner
    show that a sex change is not sought for ―wrongful or fraudulent
    that legal status by presenting objective evidence of professional
    medical treatment of the ―gender identity.‖
    49  The DSM-5—endorsed in Utah Code section 57-21-2—
    defines gender as the ―public[ly] (and usually legally recognized)
    lived role as a boy or girl, man or woman.‖ AM. PSYCHIATRIC
    ASS‘N, DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL
    DISORDERS: DSM-5, at 451 (5th ed. 2013). Utah Code section 57-21-
    2(22) says that ―sex‖ means ―gender.‖
    50  The dissent takes issue with our consideration of the Utah
    Fair Housing Act‘s language, insisting that we have ―identifie[d]
    no basis for extending [that statute‘s] definition of ‗sex‘‖ to the
    statute before us today. Infra ¶ 227. This appears to be a misplaced
    criticism of our analysis—we do not purport to extend the
    definitions contained in the Fair Housing Act across any
    boundaries separating bodies of law. Rather, we are exercising
    our duly granted authority to create a test where the legislature
    intentionally left a gap. Accordingly, we look to the Fair Housing
    Act not in reliance on its language, but merely for guidance in
    creating the test.
    54

    Opinion of the Court
    purposes.‖ Supra ¶ 103. In the sex-change context, we cannot see
    how that showing would not require objective evidence. But we
    reject the possibility that a petitioner might prove a change to
    their sex designation through evidence of ―consistent and
    uniform assertion of the gender identity,‖ but not because this is
    not objective evidence (it may well be); rather, we focus only on
    the determination provided by a licensed medical professional
    because it mirrors how sex is typically initially designated at
    birth. See supra ¶¶ 4 n.5, 105. Showing a change to one‘s sex
    designation by providing evidence of appropriate clinical care or
    treatment for gender transitioning or change by a licensed
    medical professional is exactly the kind of objective evidence that
    our jurisprudence requires. As such, it is all we require today.51
    ¶108 Second, when considering a sex change, federal
    authorities have a requirement like the one that we announce
    today. The Social Security Administration guidelines, ―Changing
    Numident Data for Reasons other than Name Change,‖ accept as
    proof of sex change, among other things, ―medical certification of
    appropriate clinical treatment for gender transition.‖ Program
    Operations Manual System, RM 10212.200 Changing Numident Data
    for Reason other than Name Change, SOC. SEC. ADMIN. (June 13,
    2013), https://secure.ssa.gov/poms.nsf/lnx/0110212200. These
    requirements specify which licensed physicians can provide such
    a statement (a doctor of medicine or a doctor of osteopathy) and
    ask the physicians to include in their ―original signed‖ statement
    full details about themselves, to include ―language stating the
    __________________________________________________________
    51 Evidence of one‘s medical history may certainly be used to
    make this showing. However, we have privacy concerns about
    requiring any evidence of medical history beyond the immediate
    treatment for gender transitioning or change, so we do not require
    any.
    We note here that the appellants before us seek a change in sex
    designation because they do not identify with the designation
    given to them at birth. They do not challenge the initial
    designation as incorrect. A future petitioner may seek a change in
    sex designation simply because the initial sex designation was
    clearly erroneous—perhaps due to a scrivener‘s error or improper
    medical observation. In such a case, medical history or other
    similar evidence may provide the necessary evidence to prove the
    change in sex designation, but we need not decide that issue here.

    IN RE SEX CHANGE
    Opinion of the Court
    physician has either treated the individual in relation to the
    individual‘s change in gender or has reviewed and evaluated the
    medical history of the individual in relation to the individual‘s
    change in gender and that the physician has a doctor/patient
    relationship with the individual,‖ and to declare that their
    statement is made ―under penalty of perjury under the laws of the
    United States that the foregoing is true and correct.‖ Id. The Social
    Security Administration‘s requirements note, however, that
    ―[s]urgery is no longer required to change the sex field on the
    [Administration‘s database].‖ Id.
    ¶109 The Social Security Administration is not alone. The
    State Department also allows for sex change on a person‘s
    passport, even before a person has completed the treatment for
    ―transition.‖ Change of Sex Marker, U.S. DEP‘T OF STATE,
    https://travel.state.gov/content/travel/en/passports/need-
    passport/change-of-sex-marker.html (last visited April 21, 2021).
    The State Department also asks for proof of ―appropriate clinical
    treatment‖ for sex changes on a person‘s passport. Id. What
    clinical treatment is appropriate is up to the physician: The
    ―physician determines what appropriate clinical treatment is
    according to acceptable medical practices, standards and
    guidelines, and certifies that [the applicants] have had
    appropriate clinical treatment for transition to either male or
    female.‖ Id. The State Department, however, specifies that
    ―[s]urgery is not a requirement to get a U.S. passport.‖ Id.
    (emphasis omitted).
    ¶110 Third, courts in other jurisdictions that lack statutory
    guidance have also required objective evidence. The Indiana
    Court of Appeals held that ―the ultimate focus [of a sex-change
    petition] should be on whether the petition is made in good faith
    and not for a fraudulent or unlawful purpose.‖ In re Change of
    Birth Certificate, 
    22 N.E.3d 707
    , 710 (Ind. Ct. App. 2014) (holding
    that the appellant in that case ―made an adequate showing in
    support of his petition‖ because ―[h]e presented ample medical
    evidence regarding his gender transition‖). Delaware and
    Maryland have also articulated an objective medical standard
    requirement, but with a connection to sex-reassignment surgery.52
    __________________________________________________________
    52 Unlike the Delaware and Maryland courts, we hold that,
    although sex-reassignment surgery may be evidence of sex
    change, it is not required. Other authorities agree. The Indiana

    factual findings of objective medical evidence provided by a
    licensed medical professional.53 See In re Davis, No. 173900047, at 2
    (Utah Dist. Ct. Second Dist. Mar. 27, 2017) (finding that
    ―[p]etitioner has been treated and is following‖ the medical
    standards of care given to the petitioner by a licensed physician
    and ―has undergone irreversible genital reassignment surgery‖);
    Court of Appeals noted that a sex-reassignment surgery is not
    required for a successful sex-change petition. In re Change of Birth
    Certificate, 22 N.E.3d at 710 n.4; see also In re Name & Gender Change
    of R.E., 
    142 N.E.3d 1045
    , 1052–53 (Ind. Ct. App. 2020) (ordering the
    lower court to grant the appellant‘s sex-change petition even
    though the appellant had not undergone a physical sex change).
    Likewise, federal authorities explicitly say that sex-reassignment
    surgery is not required. See supra ¶¶ 108–09. Nor is sex-
    reassignment surgery mentioned anywhere in Utah law. We thus
    hold that ―evidence of appropriate clinical care or treatment for
    gender transitioning or change‖ need not include sex-
    reassignment surgery. This rule is prudent given that there ―is no
    medical consensus that sex reassignment surgery is a necessary or
    even effective treatment for gender dysphoria.‖ Gibson v. Collier,
    
    920 F.3d 212
    , 223 (5th Cir. 2019); see also Boyertown, 897 F.3d at 522
    (―Treatment for children and adolescents who experience gender
    dysphoria includes social gender transition and physical
    interventions such as puberty blockers, hormone therapy, and
    sometimes surgery.‖ (emphasis added)).
    53 In In re Leavitt, the district court simply stated that it had
    ―considered the documents filed with the [c]ourt, [and] the
    evidence presented at the hearings,‖ and found ―adequate factual
    basis‖ to grant the petitioner‘s sex-change petition. Case No.
    153900411, at 1–2 (Utah Dist. Ct. Third Dist. June 8, 2015). In In re
    Caldwell, Case No. 143800043, at 1–2 (Utah Dist. Ct. Eighth Dist.
    Oct. 31, 2014), the district court‘s order did not contain findings of
    fact but approved the sex change.

    Opinion of the Court
    In re Cohen, No. 163902596, at 2 (Utah Dist. Ct. Third Dist. Jan. 3,
    2017) (noting petitioner‘s treatment under the relevant medical
    standards, as evidenced by a licensed medical professional,
    without specifying the treatment); In re Manzanares, No.
    163901747, at 2 (Utah Dist. Ct. Third Dist. Sept. 14, 2016) (same); In
    re Fairbourn, No. 163901213, at 2 (Utah Dist. Ct. Third Dist. Aug.

    Fourth Dist. Aug. 10, 2016) (same); In re South, No. 163400140, at 2
    (Utah Dist. Ct. Fourth Dist. July 8, 2016) (same); In re Walton, No.
    163700026, at 2 (Utah Dist. Ct. Seventh Dist. June 6, 2016) (same);
    In re Ivory, No. 153300116, at 2 (Utah Dist. Ct. Third Dist. Feb. 2,
    2016) (same); In re Carmichael, No. 153902067, at 2 (Utah Dist. Ct.
    Third Dist. Jan. 4, 2016) (same); In re Collins, No. 153902244, at 3
    (Utah Dist. Ct. Third Dist. Dec. 3, 2015) (same and adding that
    petitioner had ―undergone hormonal replacement therapy,‖ ―has
    been receiving female hormones for decades,‖ and had
    ―undergone gender reassignment surgery‖). Although these
    decisions have no precedential value, they show how workable an
    objective medical standard is and how it is connected intrinsically
    with a ―proper cause‖ evaluation of a sex-change petition.
    ¶112 And so, to conclude, sex-change petitions ―should
    generally be granted unless sought for a wrongful or fraudulent
    purpose.‖ See In re Porter, 
    2001 UT 70
    , ¶ 8 (quoting In re Cruchelow,
    926 P.2d at 834). They must also include, at minimum, objective
    evidence of appropriate clinical care or treatment for gender
    transitioning or change, provided by a licensed medical
    professional.
    V. THE CASES BEFORE US
    ¶113 These cases should be remanded with instructions to
    grant the petitions for sex change without any further hearing for
    three reasons.54
    ¶114 First, in both cases, the district court granted appellants‘
    petitions for name change, finding no ―wrongful or fraudulent
    purpose.‖ See In re Porter, 
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
    ; In re
    Cruchelow, 
    926 P.2d 833
    , 834 (Utah 1996). When a name change is
    connected to a person‘s sex change (as it is in these cases), we can
    conclude that the requested sex change has no ―wrongful or
    fraudulent purpose‖ if the requested name change does not.

    Opinion of the Court
    ¶115 Second, the petitioners here complied with the objective
    medical standard that we describe above. Both petitioners
    provided letters from a doctor ―stating that each of them had been
    treated for Gender [Dysphoria] and undergone ‗the appropriate
    clinical treatment‘ for the gender transition.‖ The doctors‘ letters
    complied with the Social Security Administration standard we
    detailed above.55 See supra ¶ 108. In Ms. Rice‘s case, the district
    court ―declined to make findings on these issues‖ but noted that
    two licensed physicians diagnosed and treated her for ―Gender
    Dysphoria‖ ―in accordance with‖ relevant medical standards.
    ¶116 Third, the district court‘s orders were based on a legal
    mistake. In Ms. Rice‘s case, the court only proffered its view that
    ―the procedure for obtaining a sex/gender marker change must
    be set forth by the legislature and the Court is prohibited from
    invading the legislature‘s prerogative on this issue. Thus, the
    request to change Petitioner‘s legal sex/gender marker is not a
    properly justiciable question.‖ But its denial of Mr. Childers-
    Gray‘s petition, issued eight days before that, revealed
    ―[u]nsupported generalizations‖ and concerns—considerations
    that our case law strictly prohibits. See In re Porter, 
    2001 UT 70
    , ¶ 7.
    The court proclaimed that ―[r]egardless of the sincerity or the
    intensity of the desire of any individual to display any particular
    physical appearance, some biological facts are not subject to
    voluntary modification.‖ The court then continued on what we
    can generously describe as a page of hypotheticals and slippery-
    slope arguments with no factual basis.
    __________________________________________________________
    55 And while we do not require that each petition complies
    with the Social Security Administration standard, we do
    recognize that such compliance is one way to meet the
    requirements of our test.

    IN RE SEX CHANGE
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment
    ¶117 We emphatically disavow such language and
    propositions. ―Ours is a society of written laws. Judges are not
    free to overlook plain statutory commands on the strength of
    nothing more than suppositions about intentions or guesswork
    about expectations.‖ Bostock v. Clayton Cnty., 
    140 S. Ct. 1731
    , 1754
    (2020). As for the district court‘s declaration that ―some biological
    facts are not subject to voluntary modification,‖ the reader must
    be clinically aware by now that the sex change we are discussing
    has less to do with biology than with identity. See supra ¶¶ 84–91.
    And as for the hypotheticals suggested by the district court, we
    generally frown upon unsupported slippery-slope arguments. See,
    e.g., Ipsen v. Diamond Tree Experts, Inc., 
    2020 UT 30
    , ¶ 18, 
    466 P.3d 190
    . We disapprove of them even more when they are used to
    curtail common-law-based individual rights. See In re Porter, 
    2001 UT 70
    , ¶ 7.
    ¶118 Consequently, we hold that appellants have met the
    requirements we outlined above and that their petitions for sex
    change should be granted.
    CONCLUSION
    ¶119 The adjudication of sex-change petitions lies squarely
    within the power granted to Utah courts by the Utah Constitution.
    Our district courts have the authority to adjudicate such petitions
    without any constitutional impediment. In order to prevail on
    such a petition, a petitioner must: (1) show the petition is not
    made for any ―wrongful or fraudulent purpose,‖ and (2) include
    objective evidence about the sex change reflecting the petitioner‘s
    identity, at minimum, in the form of evidence of appropriate
    clinical care or treatment for gender transitioning or change,
    provided by a licensed medical professional.
    ¶120 Mr. Childers-Gray and Ms. Rice have met these
    requirements. Therefore, we reverse and remand this case with
    instructions to enter orders granting their sex-change petitions.
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment:
    ¶121 Our task with this statute, as with any, is to endeavor to
    discern legislative intent. We have traditionally employed a
    number of tools in conducting this inquiry. We begin with the
    words of the statute themselves and, where appropriate, look to
    the structure of the statute, both internally and in relation to other
    60
    Cite as: 
    2021 UT 13
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment
    relevant statutes. A central focus of the debate between the
    majority and the minority here is whether in using the term ―sex
    change‖ the legislature intended to set a substantive standard for
    when a birth certificate may be amended to reflect a different sex,
    or rather, whether the legislature intended only to establish the
    procedural mechanism for effecting a birth certificate amendment,
    using the terms ―sex change― and ―name change‖ merely to
    identify the two types of amendments for which that mechanism
    may be employed.
    ¶122 I am persuaded by the majority‘s argument that the
    legislature did not intend its use of the term ―sex change‖ in
    section 26-2-1156 to be read as a substantive standard. I so
    conclude for a number of reasons.
    ¶123 First, I am convinced by the majority‘s argument
    regarding the broad reciprocity required by the statute. 57 Under
    the statute, the registrar is required to amend a birth certificate
    upon receipt not only of an order from a Utah district court, but
    upon receipt of an order from other states or even Canadian
    provinces. This is so regardless of the particular substantive
    standards employed by these states or provinces with respect to
    name or sex changes.58 This is not an instance of other
    jurisdictions forcing their substantive law on Utah. It is an election
    by the Utah legislature to defer to the law of other states and
    provinces with respect to name and sex changes on birth
    certificates. It suggests to me that the legislature was not so
    concerned with setting a substantive standard by its use of the
    terms ―name change‖ and ―sex change‖ as it was with identifying
    the kinds of birth certificate amendments subject to the statute. It
    further suggests to me that the legislature intended the statute to
    function as a somewhat routine procedural mechanism by which
    a birth certificate amendment may be effected, rather than as a
    substantive direction as to what constitutes a sex change. Further,
    the statute says nothing about the legal effect of a name or sex
    designation on a birth certificate.

    IN RE SEX CHANGE
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment
    ¶124 Second, I find an important interpretive clue in the
    statute‘s structure. As the majority notes, the terms ―sex change‖
    and ―name change‖ are bundled together.59 The legislature makes
    no attempt in the statute to distinguish them in any way,
    including with respect to the standard of proof. Certainly, a sex
    change is far more momentous than a name change. An
    individual‘s sex is considerably more consequential, both in
    substance and legal implication, than an individual‘s name. But
    the fact that these two kinds of changes are very different matters,
    both in magnitude and legal consequence, does not appear, given
    how the statute is structured, to be the focus of the legislature.
    Rather, the legislature appears to be focused on the way in which
    they are similar—they are both identifiers on a birth certificate.
    My reading of the statute suggests that for purposes of birth
    certificate amendment, and I emphasize this limited scope, the
    legislature intended that name changes and sex changes be
    treated in the same way, including in the standard of proof to
    which they are subject. The statute certainly includes nothing to
    suggest they should be treated differently.
    ¶125 My third reason for joining the majority on this point is
    also tied to the coupling of name change with sex change in the
    statute. Certainly no one is suggesting that the term ―name
    change,‖ as used in the statute, constitutes a substantive standard.
    I think it unlikely, given the coupling of the two terms, that the
    legislature intended the term ―sex change‖ to constitute a
    substantive standard and not the term ―name change.‖ In sum, I
    conclude that, although the statute does not purport to set forth a
    substantive standard, either with respect to a name change or a
    sex change, the legislature did, by coupling the terms, evince an
    intent that they be treated in a similar manner, including in the
    substantive standard to which they are subject.
    ¶126 While it seems clear, at least to me, that the legislature
    intended that both kinds of birth certificate amendments be
    subject to the same standard of proof, the question remains what
    standard the legislature intended. The answer is an easy one with
    respect to a name change. The standard for such a change is set
    forth in section 42-1-2. A person seeking to have a name change
    recognized by the state must establish that the change is sought

    Cite as: 
    2021 UT 13
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment
    for ―proper cause.‖ As the majority notes, we have interpreted
    ―proper cause‖ in the name change context to require that the
    change not be ―sought for a wrongful or fraudulent purpose.‖60
    ¶127 The legislature has passed no such statute with respect
    to those seeking to have a sex change recognized by the state.
    Given the structure of section 26-2-11, which couples name and
    sex changes and makes no attempt to suggest they should be
    subject to different standards, I think it reasonable to conclude
    that the legislature intended to impose no greater burden on those
    seeking a name change on their birth certificate than those seeking
    a sex change on their birth certificate. This may or may not be
    good policy, but that is of no consequence for our interpretive
    task. Our role is to ascertain legislative intent. And I see nothing
    in the language or structure of the statute suggesting that the
    legislature intended that the two types of birth certificate
    amendments be subject to different standards of proof. I would
    therefore employ the same proper cause standard the legislature
    has explicitly adopted for name changes to those seeking to have
    their birth certificate amended to reflect a sex change. And I
    would interpret the term ―proper cause‖ for purposes of a sex
    change amendment to a birth certificate in the same way we have
    interpreted that term in the name change context—to require that
    the petitioner show the change is not sought for a wrongful or
    fraudulent purpose.
    ¶128 While everything I have written to this point is
    consistent with and supportive of the majority opinion, I do part
    paths in some respects.
    ¶129 I would not, as does the majority, invoke our common
    law authority in this case, except to the extent that I would look to
    our caselaw on the question of how we have interpreted the
    statutory standard of proper cause in the name change context. In
    other words, I do not think it necessary for us to rely upon the
    majority‘s argument that, by presupposing a district court‘s
    authority to order name and sex changes the legislature
    ―conferr[ed] on sex-change adjudication the common-law

    IN RE SEX CHANGE
    CHIEF JUSTICE DURRANT, concurring in part, dissenting in part,
    and concurring in the judgment
    authority existing with respect to name-change adjudication.‖61 I
    see the problem more as one of statutory interpretation.
    ¶130 In summary, my view of the appropriate interpretation
    of the statute proceeds as follows: (1) although the structure of
    section 26-2-11 indicates a legislative intent that name and sex
    change amendments to a birth certificate be subject to the same
    procedural mechanism and the same standard of proof, the
    statute does not provide that standard; (2) section 42-1-2 does,
    however, provide a standard for a name change – proper cause;
    (3) in light of the legislature‘s apparent intent that name and sex
    changes be treated uniformly, I would apply this same proper
    cause standard to those seeking to amend their birth certificate to
    reflect a sex change. In other words, rather than looking to the
    common law, I would look to section 42-1-2 for the appropriate
    standard. Although the majority does rely upon section 41-2-2 for
    the first part of its proposed standard, it relies solely upon the
    common law for the second part.62
    ¶131 The majority articulates its two-part standard in this
    way: first, sex-change petitions ―should generally be granted
    unless sought for a wrongful or fraudulent purpose‖;63 and
    second, ―they are supported by objective evidence of a sex change,
    which includes, at minimum, evidence of appropriate clinical care
    or treatment for gender transitioning or change, provided by a
    licensed medical professional.‖64 I would characterize the
    applicable standard differently. In order to more closely parallel
    the statutory standard for name changes, I would stop at the
    majority‘s first prong. So my proposed standard would simply be
    that a person seeking a birth certificate amendment to reflect a sex
    change must establish that the change is sought for proper cause.
    And I would interpret the term ―proper cause‖ as does the
    majority, and as our court has done in the past, to mean that the
    change is not sought for a wrongful or fraudulent purpose.

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶132 But rather than requiring objective evidence of
    treatment as an independent second requirement, I would
    characterize such evidence as one category of evidence that may
    be employed by a petitioner in order to establish proper cause.
    And I would conclude that the two petitioners in the case before
    us have provided more than ample evidence, medical and
    otherwise, of proper cause. So I would not set forth a definitive
    minimum standard for what must be shown to establish proper
    cause by a petitioner seeking a sex change amendment to a birth
    certificate. The structure of section 26-2-11, which presupposes the
    authority of the court to issue name and sex change orders
    without providing a standard of proof, as well the legislature‘s
    use of the broad ―probable cause‖ standard in section 42-2-1
    (which I argue is the most likely candidate for the legislature‘s
    intended standard for sex changes) both suggest a legislative
    intent that district court judges be accorded broad discretion with
    respect to these matters. I would allow the parameters of the
    scope and nature of the evidence necessary to establish proper
    cause under section 26-2-11 to develop over time, as district court
    judges exercise this broad discretion.
    ¶133 I have made my best effort to read the tea leaves of the
    legislature‘s intent in passing section 26-2-11. And I have great
    respect for the scholarly and thorough opinions authored by
    Justice Himonas and Associate Chief Justice Lee. They are both
    sincere attempts to answer a difficult interpretative question. But
    it should be noted that, despite our best efforts, in the end it is, as
    it should be, the legislature that has the last word. If it disagrees
    with the interpretations of section 26-2-11 we have advanced in
    these three opinions, the legislature of course has the power to
    amend the statute or pass an altogether different statute. And in
    the event it decides to do either, these opinions should prove
    helpful in that effort because, taken together, they provide a
    rigorous and in-depth exploration of both sides of the issues in
    this important area of the law.

    ¶134      I endorse the values of personal dignity and

    respect I pay to others. I have paid and will pay such respect in

    their right of self-determination.

    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶135     I have personal, moral grounds for so doing. Yet this
    is not a case about personal interactions or individual morality. It
    is a case about government records, and the legal grounds for
    amending them. Those grounds are controlled by law. And the
    law in question leaves no room for the decision made by this court
    today.
    ¶136     Since 1975 the Utah Code has provided for a court
    order directing an amendment to a birth certificate‘s ―sex‖
    designation. For decades this designation has been understood as
    a reference to biological sex—a determination made at birth,
    based on physical observation. But the petitioners ask us to
    transform the designation of biological sex into a designation of
    gender identity. They assert that their gender identity is not in line
    with their biological sex at birth. And they ask us to reform our
    law in a manner allowing an amended entry on their birth
    certificates reflecting their gender identity instead of their
    biological sex.
    ¶137     Today a majority of our court accepts that invitation.
    It takes the statutory reference to sex as an invitation for our court
    to inject new meaning into the statute by making common-law
    policy in this field. Supra ¶ 16. And it exercises that policymaking
    power by establishing a new law that is as permissive as any law
    in any state in the union, under a right to an amended birth
    certificate for any person who has received ―appropriate clinical
    care or treatment for gender transitioning or change.‖ Supra ¶ 112.
    ¶138    The court claims to be establishing an ―objective‖
    standard based on medical evidence. Supra ¶ 112. But the
    majority‘s standard does not require a medical diagnosis or
    prescribe an objective benchmark. It provides for an amendment
    to a birth certificate whenever a petitioner asserts that he or she
    has received ―appropriate‖ care or treatment for ―gender
    transitioning.‖ See supra ¶ 112; see also supra ¶ 105 n.46 (citing the
    DSM-5 criteria for diagnosis of ―gender dysphoria‖ but stating a
    standard that requires no diagnosis but only a showing of
    ―appropriate clinical care or treatment‖). This is not the statutory
    concept of sex for a Utah birth certificate. It is a complete
    transformation of that longstanding concept by a majority of this
    court.
    ¶139    I dissent from this decision. It is a double departure
    from longstanding limits on our judicial power. The court is
    exceeding the bounds of our jurisdiction in deciding a case in
    which there is no adverse party—only a request from those
    66
    Cite as: 
    2021 UT 13
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    seeking an amendment to their birth certificates. And it is
    overriding the terms of the Utah Code in treating a reference to a
    change in the biological sex determination made at birth as an
    invitation for our courts to make new law in an exercise of
    common-law policymaking power.
    ¶140     This decades-old statute is not a delegation of
    common-law policymaking power. It is a reflection of the settled
    understanding of the concept of sex as reflected on a birth
    certificate. The underlying concept is clear with regard to the
    designation made at birth, as the majority itself concedes. See
    supra ¶ 85 (acknowledging that it is ―generally understood‖ that
    the designation of sex at birth ―is based on a medical observation
    of genitalia and physical characteristics‖); supra ¶ 89 n.40 (noting
    that Utah law contemplates that ―health care professionals‖ will
    submit birth ―certificates based on purely medical observations‖);
    supra ¶ 104 (conceding that ―a person‘s initial sex‖ designation is
    based on ―a medical evaluation made according to objective
    observation at birth‖). And the same concept should be
    understood to be carried forward to the analysis of the basis for an
    order for an amendment to that same designation.
    ¶141     The statute itself does not expressly articulate a
    ―substantive standard‖ for entry of the order. See supra ¶ 54. But
    the statute does speak to the type or ―kind[] of birth certificate‖
    designation that is subject to change under the statute. Supra ¶ 78
    n.33. And the lack of any further standard accordingly cuts
    against the notion of legislative delegation of common-law
    policymaking power. It suggests that the statute was plowing no
    new ground, and thus that the contemplated order for an

    the presumption that the established meaning of a word in a
    given body of law carries over to other uses of the same term used
    elsewhere within that same law. See Cannon v. McDonald, 
    615 P.2d 1268

    concept of biological sex would be a large elephant. And a statute
    speaking only to the effect of a court order is a tiny mousehole.
    ¶143    The problem is reinforced (not averted) by the fact
    that the statutory reference to a change in a person‘s ―sex‖
    designation is ―combined‖ with a reference to ―name change.‖
    Supra ¶ 50. There is in fact a ―common law‖ understanding of
    ―name change.‖ But there is no common law governing any
    change to the sex designation on a birth certificate. And the
    majority opinion in this case is not applying an established
    common-law standard (under the law of name changes or
    otherwise); it is formulating its own new standard out of whole
    cloth. For that reason the cited distinction cuts against the
    majority‘s approach. The legislative decision to ―combine‖ an
    established common-law term with a term that has an established
    meaning in statutory administration indicates an intent to
    attribute common-law meaning to the common-law term and
    statutory meaning to the statutory term.
    ¶144      The court‘s contrary conclusion is no small matter. On
    its face, the majority decision is limited to birth certificates. But a
    birth certificate is an indicator of a person‘s sex when presented to
    our schools65 and other institutions. And the majority decision
    will have far-reaching implications in these and other spaces. It
    seems destined, for example, to affect spaces traditionally
    reserved for biological girls and women—sex-segregated sports
    leagues,66 school locker rooms, 67 and shelters designed as safe

    range of sensitive matters of enormous significance to our
    society.69
    ¶145     The question of whether and how to balance these
    interests in the adoption of a new law in this field is a matter for
    the Utah legislature. That is a political body representing a wide
    range of ideologies and interests, with the manner and means of
    amending the laws on the books based on input from a diverse
    constituency and a wide range of views—through committee
    hearings, open debate, and a public vote. 70 This court is in no such
    __________________________________________________________
    69   The district court catalogued a series of these matters—
    raising concerns about the effects of a birth certificate amendment
    based on a person‘s ―gender identity‖ on ―insurance rates,‖
    ―preferred contracting‖ (under affirmative action laws), athletic
    competitions, prisons, and more. Yet the majority brushes these
    concerns aside as ―suppositions‖ and ―guesswork,‖ or ―slippery-
    slope arguments with no factual basis.‖ Supra ¶¶ 116–17. It also
    criticizes me for identifying a range of parallel concerns,
    suggesting that I have somehow crossed a line as an advocate for
    ―the interests of the State.‖ Supra ¶ 3.
    This is unfair and unfounded. No adverse party has been
    given the opportunity to present any adverse position on the
    merits in this case. And with that in mind, Judge Hyde and I are
    both engaged in a similar endeavor—not in arguing for a
    preferred disposition or advocating for any particular view, but in
    identifying the third-party interests that are resolved by but have
    not been heard by the court. In my view it is not a vice but a
    virtue for a judge to highlight these concerns in the course of
    challenging the propriety of our exercise of jurisdiction.
    The majority‘s approach on these matters is also riddled with
    irony. On one hand, the court insists that the traditional adversary
    model is no jurisdictional barrier to its determination to reach the
    merits of the question presented. On the other hand, the court
    takes the opposite tack when it comes to its analysis of the
    questions presented on the merits—asserting that any contrary
    concerns are off the table, as unbriefed by any adversary party.
    The court can‘t have it both ways. Either adverseness is required
    or it isn‘t.
    Our Utah legislature is certainly in a position to extend our
    70
    law to capture ―gender identity‖ instead of ―sex‖ on an
    amendment to a birth certificate, or to take other measures aimed

    position71—least of all in a ―case‖ like this one, in which the court
    has heard from only one side of this difficult problem.
    ¶146    We lack the judicial power to make this decision in a
    case in which there is only a petitioning party and no adversary.
    Our courts have long been limited to the adjudication of
    adversary proceedings—cases involving the establishment of a
    petitioning party‘s rights at the expense of an adversary. The
    court overrides that longstanding limit—and the decades of
    precedent that establish it—in holding that our courts now have
    the authority to resolve any ex parte request for a change to any
    matter of ―legal status or identification.‖ Supra ¶ 15. This new
    standard of jurisdiction is limitless. It obliterates the long-settled
    line between executive and judicial power.
    at balancing the competing interests implicated by this case. But
    to date, it has not done so. In 2018 and 2019, the legislature
    considered proposed amendments to the birth certificate law. H.B.
    153, 2019 Leg., Gen. Sess. (Utah 2019); S.B. 138, 2018 Leg., Gen.
    Sess. (Utah 2018). And in the 2021 session, it considered a bill that
    would have regulated the eligibility of transgender persons to
    participate in sex-segregated sports in Utah. H.B. 302, 2021 Leg.,
    Gen. Sess. (Utah 2021). None of these proposals was enacted into
    law or even came to a final floor vote. And none of these bills
    proposed to allow a birth certificate amendment based on
    evidence of appropriate care or treatment for gender transitioning
    or change.
    Our court is thus getting ahead of the people‘s representatives
    in the legislature. And it is doing so without the benefit of any
    open, public debate or opportunity for input from competing
    stakeholders.
    71  Increasingly our society is giving in to this impulse. Too
    often we are caving to the pressure to ―solv[e] political differences
    . . . through litigation rather than through legislation and
    elections.‖ See In re Trump, 
    958 F.3d 274
    , 293 (4th Cir. 2020)
    (Wilkinson, J., dissenting), vacated as moot by Trump v. D.C., 
    141 S. Ct. 1262
     (2021). This is troubling. It is a ―profoundly anti-
    democratic development,‖ id.—a perilous shift of power from the
    people and their representatives to a body of unelected officials
    whose black robes have long given us the appearance of
    impartiality. That appearance is fragile. We should do all we can
    to retain it.

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶147     Prudential considerations would call for an order for
    adversary briefing even if the constitutional limits on our power
    did not. When other courts have been faced with the prospect of
    resolving an important legal question with briefing from only one
    side, they consistently have appointed an amicus to represent and
    advance the views of the missing opposition. This seems crucial in
    a case like this one, in which there clearly are interests on both
    sides, and the court is resolving them as a matter of common-law
    policymaking. The decision to plow ahead without adversary
    briefing is unwise even if it is not an excess of our power.
    ¶148      The majority‘s decision may be perceived by some as
    a triumph of freedom and self-determination. It cannot be
    applauded, however, as a triumph for our Utah laws or
    constitution. The majority is effectively rewriting a statute enacted
    by the legislature in 1975. And it is doing so in a case in which we
    lack any adverse party or adversary briefing—under a novel
    formulation of our courts‘ jurisdiction that effectively overrides
    the long-settled limits on the judicial power.
    ¶149     I respectfully dissent from this decision. I explain my
    reasoning further in the paragraphs below. First, I develop the
    basis for the conclusion that we should not be resolving this
    matter in a proceeding in which there is no adverse party and no
    adversary briefing. Second, I demonstrate that the statute
    approving an order for a change to the designation of a person‘s
    ―sex‖ on a birth certificate is speaking to biological sex and is not
    delegating to this court the power to establish an evolving
    standard of ―gender identity.‖ Finally, I close with some final
    observations about the nature of my objections to the
    extraordinary decision made by the court today.

    id. art. VII, § 5, while the Attorney General is designated as ―the
    legal adviser of the State officers‖ and directed to ―perform such
    other duties as provided by law.‖ Id. art. VII, § 16. These executive
    powers involve decisions based on ―individualized, case-specific
    considerations as to whether the acts of a particular person fall
    within the general rule adopted by the legislature.‖ Carter, 
    2012 UT 2

    administrative acts aimed at applying the law to particular
    individuals or groups based on individual facts and
    circumstances.‖ Id. ¶ 34.
    ¶153     The ―judicial power‖ under our constitution is ―vested
    in a Supreme Court, in a trial court of general jurisdiction known
    as the district court, and in such other courts as the Legislature by
    statute may establish.‖ UTAH CONST. art. VIII, § 1. This power ―is

    controversies between adverse parties and questions in litigation.‖
    Citizens’ Club v. Welling, 
    27 P.2d 23

    power is thus distinct from the legislative or executive power. We

    an actual controversy directly involving rights‖ of adverse parties.

    This is because the promulgation of such general, abstract rules is

    Those are inquisitorial functions, which our courts are ill-
    equipped to perform. The judicial power is the power to
    adjudicate rights in an adversary posture. Our courts establish the
    rights of petitioning parties upon the satisfaction of responding
    parties.
    ¶155      This is a fundamental tenet of the separation of
    powers under the Utah Constitution. It has deep roots in our
    Anglo-American legal tradition, tracing at least as far back as
    Blackstone‘s Commentaries. Blackstone put the point in terms of
    ―three constituent parts‖ of a judicial proceeding: ―the actor, or
    plaintiff, who complains of an injury done; the reus, or defendant,
    who is called upon to make satisfaction for it; and the judex, or
    judicial power.‖74

    come under recent challenge. In an article in the Yale Law Journal,
    James E. Pfander and Daniel D. Birk identified examples of
    purportedly non-contentious matters heard historically by our
    courts, including cases involving bankruptcy petitions,
    receiverships, warrants, and petitions for pensions and
    citizenship. James E. Pfander & Daniel D. Birk, Article III Judicial
    Power, the Adverse-Party Requirement, and Non-contentious
    Jurisdiction, 124 YALE L.J. 1346 (2015). These authors cited these
    and other examples in support of the view that the judicial power
    is not limited to the resolution of ―adverse‖ disputes. Id. at 1346
    (asserting that the judicial power encompasses ―power over
    disputes between adverse parties‖ and ―power over ex parte and
    other uncontested proceedings‖). They thus challenged the
    viability of an established justiciability doctrine by contending
    that the federal courts may ―plausibly‖ be viewed to have been
    ―given . . . the authority to exercise judicial judgment in the
    administration of federal law ‗cases‘ on an ex parte or non-
    contentious basis‖ as assigned by Congress. Id. at 1425.
    ¶158     Two members of our court have echoed this challenge

    ¶159    Today‘s majority finds ―much to commend‖ in this
    challenge to our longstanding precedent in this important field.
    
    Supra
     ¶ 20 n.13. And it proceeds to the conclusion that we have
    jurisdiction to resolve the ―case‖ before us despite the lack of
    adverseness—even while insisting that there is no need for us to
    ―reach the issue‖ of whether to abandon our longstanding case
    law. Supra ¶ 20 n.13.
    ¶160     The court‘s holding, however, effectively erases the
    traditional, longstanding requirement of adverseness. In its place,
    the court introduces a new standard: Our courts may exercise
    jurisdiction over any petition aimed at changing a party‘s ―legal
    status or identification.‖ Supra ¶ 21. But this new standard has no
    bounds. It opens the door to judicial resolution of any of a range
    of matters falling within the power of the executive.
    ¶161     This is troubling. It is also unsupported by the cited
    examples of purportedly non-adversary proceedings. The cited
    examples are adversarial in the above-noted sense—they involve
    the adjudication of a petitioning party‘s rights at the expense of a
    responding party. That is all that is required to justify the exercise
    of judicial power. Adverse argument is not required, just the
    disposition of adverse interests.
    ¶162     This is clear from the above-noted Blackstone
    formulation—in the requirement of an ―actor, or plaintiff, who
    complains of an injury done,‖ and a ―reus, or defendant, who is
    called upon to make satisfaction for it.‖ 3 WILLIAM BLACKSTONE,
    COMMENTARIES *25 (third emphasis added). Our courts have
    power to resolve this sort of controversy or clash of adverse
    interests. We exercise judicial power when we establish one
    party‘s interest at the expense of another party (who makes
    ―satisfaction‖ of the pleading party‘s interest).
    ¶163   This is not what our court is being asked to do here.
    Here we are being asked to alter or establish these plaintiffs‘
    rights under the law in general. No adverse party‘s rights are
    extinguished or adjudicated in the course of the requested
    decision. And that renders this a non-judicial proceeding—a
    matter akin to a request for issuance of or amendment to a
    government document, license, or permit.
    ¶164     We should dismiss this case for lack of jurisdiction
    under this deeply rooted understanding of the judicial power.
    And even if we could somehow overcome this barrier as a matter
    of our jurisdiction, we should nonetheless order adversary
    briefing as a matter of discretion or prudence.

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶165     I highlight the grounds for my conclusions below in
    (a) noting that the historical understanding of the judicial power
    requires a disposition of adverse interests (but not always adverse
    argument); (b) explaining that the cited examples of non-
    contentious proceedings fit this understanding of adverseness; (c)
    demonstrating that historical name-change proceedings do not
    establish a basis for the court‘s novel formulation of the judicial
    power—a formulation that effectively overrules decades of our
    precedent; and (d) emphasizing the prudential need for notice
    and adversary briefing even if it is not required for our exercise of
    jurisdiction.
    A.       The Judicial Power and the Disposition of Adverse
    Interests
    ¶166      Not every judicial act involves a disposition after
    adverse argument by opposing parties. Our courts have long been
    involved in proceedings in which opposing interests are forfeited
    or waived. And the judicial resolution of these matters may be
    viewed to ―fall within the ‗judicial power‘‖ despite the lack of
    adversary briefing. In re Gestational Agreement, 
    2019 UT 40
    , ¶ 13,
    
    449 P.3d 69
    .
    ¶167     This provides a credible basis for skepticism of the
    notion of a requirement of adverse argument. But it is no basis for
    repudiation of the adverseness requirement altogether. It just
    highlights the need for clarification of the nature of the
    requirement.
    ¶168     The clarification is highlighted in a recent article
    responding to Pfander and Birk‘s Yale Law Journal piece. In the
    response article, Ann Woolhandler addresses the ―non-
    contentious‖ litigation examples identified by Pfander and Birk.
    She notes that the historical cases distinguish two aspects of
    adverseness: (a) ―a requirement of adverse legal interests that will
    be affected by a decree‖; and (b) ―a requirement of adverse
    advocacy interests or adverse legal arguments.‖77 And she
    establishes that only the former is required as a matter of
    historical practice.

    interests upon notice and an opportunity for those interests to be

    heard. But a court‘s jurisdiction does not disappear if adverse
    parties fail to or agree not to appear in opposition. 78 The failure to
    appear does not make the case non-adversarial; it just makes it
    uncontested.79
    B.        Uncontested Proceedings as Adverse
    ¶170     Judges resolve uncontested adversary proceedings
    with regularity. Collection actions are a common example. Other
    examples include some of the historical cases cited as exceptions,
    like uncontested adoptions and probate proceedings. An
    uncontested adoption is an adversary proceeding in the sense that
    there is a petitioning party (the adoptive parents) whose rights are
    established at the expense of an adverse party (the birth parents,
    whose rights are terminated). A probate action is also adversary—
    it is initiated by notice to the public of the pendency of an action
    in which any and all claimed interests in the res (the estate) are
    adjudicated.80
    ¶171      Such actions are thus adverse in the sense that a
    plaintiff‘s rights are established at the expense of a defendant.

    There is an ―actor, or plaintiff‖ and a ―reus, or defendant,‖ and the
    ―judex, or judicial power‖ involves the establishment of the
    plaintiff‘s legal interests at the expense of or upon ―satisfaction‖
    by the defendant. 3 WILLIAM BLACKSTONE, COMMENTARIES *25.
    None of this requires adverse legal argument, however; the
    defendant‘s interests may be disposed of by waiver or default.
    ¶172     The Woolhandler article demonstrates that the
    historical examples in the Pfander and Birk piece are along these
    lines—and do not establish that adverseness is not an element of
    traditional judicial power.81 As to bankruptcy petitions and
    receiverships, Woolhandler explains that these are forms of in rem
    jurisdiction, in which the courts were resolving disputed interests
    in a given matter upon notice and opportunity for adverse
    argument.82 As to petitions for the determination of a right to a
    pension, the author cites the determination in Hayburn’s Case that
    an ex parte determination of a claim by a pensioner would not be
    an act in a ―judicial nature,‖83 and emphasizes that many of the
    historical cases were resolved by ―commissioners‖ rather than
    judges exercising judicial power under Article III.84 Finally, the
    author concedes that petitions for naturalization of citizenship are
    perhaps the ―best example‖ of non-contentious jurisdiction.85 But
    she emphasizes that judicial disposition of these petitions
    involved a recognition of a petitioning party‘s rights (citizenship)
    at the expense of an adversary (the sovereign)—an adversary

    construct requiring ―notice to‖ and ―potential appearance by‖ the
    United States government as the obvious ―adverse party.‖86
    ¶173     This basis for federal jurisdiction over naturalization
    proceedings is reflected in the territorial court‘s decision in In re
    Kanaka Nian, 
    21 P. 993
     (Utah 1889)—a case cited by the majority in
    support of its assertion of jurisdiction. See supra ¶ 67. This was
    indeed a proceeding in the territorial court involving a petition for
    naturalization of citizenship. But it provides no support for the
    majority‘s assertion of jurisdiction over all changes to ―legal status
    or identification‖ despite a lack of adverse interests. The United
    States government was the adverse party in that case. This was an
    adversary proceeding in which the applicant‘s citizenship was
    established upon satisfaction of any contrary claim by the
    government. Counsel ―were heard for and against the admission
    of the applicant.‖ Id. at 993; see also id. at 994 (noting that the
    petition ―was opposed . . . on the ground that [the petitioner] did
    not appear to be possessed of sufficient intelligence to become a
    citizen‖).
    ¶174     This view of naturalization proceedings is likewise
    reflected in the Supreme Court‘s opinion in Tutun v. United States,
    
    270 U.S. 568
     (1926). There the Court noted that ―[t]he United
    States is always a possible adverse party‖ in naturalization
    proceedings. 
    Id. at 577

    traditional understanding of adverseness—as a requirement of
    adverse interests, not adverse argument.87

    Id.
    87  The majority responds by asserting that the ―distinction
    between adverse ‗argument‘ and ‗interests‘ swallows itself‖
    because ―a court could always identify a ‗possible‘ adverse party
    for any matter before it.‖ Supra ¶ 27. But this misses the point of
    the requirement of adverseness—and of the distinction between
    adverse interest and adverse parties. An adverse proceeding
    arises not upon ―mere speculation of possible adverse interests,‖
    supra ¶ 27, but in a controversy in which the petitioning party‘s
    interests are established at the expense of the responding party‘s
    rights. When the government establishes a petitioning party‘s
    rights in the abstract—in a non-adversary proceeding, as in the
    issuance or amendment of a government record, license, or
    permit—it is exercising executive power. The judicial power is

    ¶175     This framework is also reinforced by our own
    precedent, most recently in In re Gestational Agreement. In that case
    we reinforced the longstanding general rule that our courts lack
    jurisdiction ―in ‗the absence of any justiciable controversy
    between adverse parties.‘‖

    Brown, 
    2014 UT 6
    , ¶ 29,

    ). But we upheld the
    jurisdiction of our courts to decide on the enforceability of an
    uncontested gestational agreement under the Utah Uniform
    Parentage Act. In so doing, we analogized such a proceeding to an
    uncontested adoption—a proceeding long heard by our Utah
    courts. See 
    id.
     ¶¶ 14–15 (noting that the territorial and early Utah
    courts adjudicated uncontested adoptions). And with that
    historical practice in mind, we held the adjudication of parental
    rights would fall within the scope of the judicial power as
    understood ―by the framers of our constitution‖ despite the lack
    of any contest or adverse argument by birth parents. Id. ¶ 13.
    ¶176    The Gestational Agreement majority did not use the
    express terminology of ―adverse interests‖ and ―adverse
    argument.‖ But the court‘s holding is clearly rooted in these
    settled principles. The court first noted that uncontested
    adoptions are non-adversarial in the sense that the birth parents
    have agreed in advance to waive their right to present adverse
    argument as to their interests in the child. See id. ¶ 14–15 (noting
    that biological parents were required to give advance consent to
    the termination of their rights in founding-era uncontested
    adoption proceedings). Next, it indicated that an adoption order
    nonetheless involves a disposition of adverse interests—in an
    order establishing the adoptive parents‘ rights at the expense of
    (or upon termination of) the biological parents‘ rights.
    ¶177     The Gestational Agreement court thus held that the
    original understanding of the judicial power encompasses the
    authority to hear uncontested cases involving ―the termination
    different. It involves the establishment of a petitioning party‘s
    rights at the expense of an adverse party.
    This is not ―the dissent‘s distinction.‖ Supra ¶ 27. And it is not
    a principle emanating from a recent ―law review article.‖ Supra
    ¶ 26. It is the core premise of the judicial power established by
    centuries of jurisprudence. And that premise is overridden by the
    majority today.

    and creation of parental rights.‖ Id. ¶ 16 (emphasis added). It
    characterized such cases as ―non-adversarial.‖ Id. But the
    proceedings in question were ―non-adversarial‖ only in the sense
    that they were uncontested—or in other words lacked adverse
    argument. And the Gestational Agreement opinion framed the
    category of ―non-adversarial‖ proceedings that it found to fall
    within the original understanding of the judicial power in terms
    that made clear that adverse interests were implicated. See id.
    (holding that ―the judicial power includes the power to hear non-
    adversarial proceedings when these proceedings involve parental
    rights‖ (emphasis added)).
    ¶178    The Gestational Agreement opinion cannot be viewed to
    have abandoned the requirement of adverseness more generally.
    It does not stand for the proposition that our courts have the
    power to ―adjudicate‖ any category of case over which we have
    been ―granted . . . substantive power‖ by the legislature,
    ―regardless of adversariness.‖ Supra ¶ 25. The Gestational
    Agreement majority does the opposite. It reinforces that
    adverseness is the general rule. And it recognizes only a limited
    exception to that rule—as to a category of cases in which there are
    adverse interests but no adverse argument.
    ¶179      The majority today is erasing the careful lines drawn
    in Gestational Agreement and overriding the longstanding
    requirement of adverseness. In so doing it is vindicating the
    position staked out by Justice Pearce in his concurrence in
    Gestational Agreement—an opinion that suggested that our court
    has never ―squarely confronted‖ whether ―the judicial power
    constitutionally vested in our courts contains a general
    requirement of ‗adversariness‘‖ and encouraged ―exploration‖ of
    the issue ―in further cases.‖ Id. ¶¶ 56–57 (Pearce, J., concurring);
    see also id. ¶¶ 63, 68–70 (suggesting that there is historical evidence
    that both Utah and federal courts historically ―presided over
    nonadversarial proceedings‖ and that this court could benefit
    from ―additional briefing and analysis‖). The majority claims to
    be stopping short of endorsing this position. See supra ¶ 20 n.13
    (finding ―much to commend‖ in Justice Pearce‘s concurring
    opinion but insisting that the court is not ―conclusively deciding‖
    whether to adopt it). But the court‘s expressed standard is
    incompatible with the Gestational Agreement majority. It effectively
    holds that adverseness is no longer required in its assertion that
    we can exercise judicial power over any case over which we have
    been ―granted . . . substantive power‖ by the legislature. Supra

    ¶180     This is not our law. A ―justiciable controversy‖ does
    not always produce adversary briefing. Yet it does require the
    disposition of adverse interests—upon notice to and an
    opportunity for briefing from known adverse parties. An
    adversary party may forfeit its interest (by default) or waive it in
    advance (by consent—as with an uncontested adoption or
    gestational agreement). A court lacks the power to establish a
    petitioning party‘s rights, however, if it is not doing so at the
    expense of or upon satisfaction by a responding party.88
    C.      Name Change Proceedings and the Court‘s Rejection of
    the Requirement of Adverseness in favor of a New General Rule
    ¶181     The history of name-change proceedings is no basis
    for a decision to abandon the longstanding requirement of
    adverseness. Some name-change actions amount to adverse in rem
    proceedings akin to probate matters—actions in which the
    petitioning party‘s rights are established at the expense of any
    adverse interests after public notice of this prospect. A prime
    example would be a name change action that could effect identity
    fraud or debt avoidance.89 This sort of name-change action would

    ). But our constitutional principles are derived in the
    first instance from the original understanding of the text of the
    constitution. And the original understanding of the judicial power
    has long been viewed to encompass the requirement of
    adverseness. We should not abandon that principle at the first
    sight of an ―analogy‖ that might seem to run counter to it. But see
    supra ¶ 34 (concluding that the analogy of name-change
    proceedings overrides the requirement of adverseness and
    establishes the principle that courts have power to adjudicate non-
    adversarial ―status‖ determinations).

    be an adverse proceeding in which the court would give notice to
    any adverse parties.90
    ¶182     Other    name-change       proceedings     are    less
    consequential, and less obviously adverse. In a run-of-the-mill
    name-change action, the petitioner is simply changing a surname
    to reflect an adoption or marriage, or changing a first or middle
    name in a manner that has no potential to resolve the interests of
    any third parties. Such an action would not be viewed as adverse
    in the sense of the petitioning party‘s rights being established at
    the expense of a defendant‘s. And in that sense, name-change
    actions may seem to stand as a historical exception to the general
    rule of adverseness.
    ¶183      But that still leaves the question of the inference to
    draw from this historical exception. The identification of an
    exception need not disprove the general rule—much less require
    that we displace it with a new rule. Sometimes an exception is just
    an exception—a narrow carve-out from the scope of a general
    rule, or in other words a ground for refining the general rule.
    ¶184    That is the proper course to take where the general
    rule is so deeply rooted and so consistently stated. The
    requirement of adverseness is a longstanding limit on the judicial
    power. It is a fundamental protection against excesses of the
    judiciary, rooted in the foundations of Anglo-American
    government and restated by this court from the time of its
    founding. We should not abandon it at the first sight of an
    apparent aberration.
    ¶185      The majority does essentially that. Instead of just
    endorsing a name-change exception to the general requirement of
    adverseness, the majority establishes a new general rule—the rule
    that our courts can adjudicate any case over which we have been

    new rule has no limiting principle. It effectively overrides decades
    of Utah precedent and centuries of settled practice in our Anglo-
    American system of justice.
    ¶189     Any administrative act by the executive branch can be
    viewed as affecting ―legal status.‖ The disposition of a party‘s
    legal rights is the establishment of ―legal status.‖ The new rule
    would thus logically encompass any of a range of the most
    classically executive functions—including decisions on whether
    and how to prosecute a suspect and whether or how to issue or
    amend any government record, license, or permit.91

    ¶190     Under today‘s decision, our courts are thus no longer
    restricted to the exercise of traditional judicial power. We share
    the core power of the executive branch. We can make
    administrative decisions heretofore restricted to the executive.
    And we can do so in the absence of any disposition of or
    opportunity for input from any adverse interests.
    ¶191     I dissent from this sweeping decision. The history of
    name-change proceedings does not provide a basis for jurisdiction
    over all ex parte ―status or identification‖ proceedings. At most it
    establishes a basis for a narrow exception to our settled general
    rule.
    ¶192     For these reasons I would hold that the legislature
    lacks the power to delegate to the courts the power to resolve the
    kind of petition at issue in this case. The petitions before us ask
    that we establish the petitioning parties‘ ―legal status‖ under the
    law without adjudicating any responding party‘s competing
    (alteration in original). I am simply noting that licensing and
    permitting are settled examples of core executive power—
    government acts establishing a petitioning party‘s ―legal status‖
    in the abstract instead of at the expense of a responding party‘s
    rights. And it is the majority that has failed to explain how its new
    ―legal status or identification‖ standard can be reconciled with the
    settled limits on our judicial power, or interpreted in a manner
    that preserves any distinct function for the executive.
    The court insists that ―areas of the law traditionally regulated
    by the executive‘s permitting and licensing function are
    distinguishable from matters involving legal status or
    identification.‖ Supra ¶ 70. But it never identifies any plausible
    basis for distinction. The closest it comes to an attempt at a
    distinction is the assertion that executive ―licensing and
    permitting‖ are based primarily on ―public safety purposes,‖
    while judicial ―legal status‖ determinations are not. Supra ¶ 70
    n.29. The proposed distinction fails, however, at both ends of the
    divide. The executive power has never been deemed to be limited
    to the pursuit of ―public safety purposes.‖ And the judicial power
    clearly spans more than just ―legal status or identification.‖
    The court‘s new lines are problematic. They bear no relation to
    the established terms and conditions of the executive and judicial
    power.

    under well-settled law. And we have the duty to assess our
    jurisdiction sua sponte, regardless of the lack of any briefing that
    challenges it. See UTAH R. CIV. P. 12(h)(2); In re Adoption of B.B.,

    ¶193    It is thus no answer to note that ―no party‖ has
    challenged our jurisdiction or questioned the constitutionality of
    Utah Code section 26-2-11 as applied to this case. See supra ¶ 68
    (stating that ―no party‖ has argued that we lack jurisdiction or
    sought to challenge the presumption of constitutionality). That is
    hardly surprising given that the only parties to this case are those
    that are asking us to invoke our jurisdiction in their favor. Our
    statutes are admittedly entitled to a presumption of
    constitutionality. See South Salt Lake City v. Maese,

    & n.37, 
    450 P.3d 1092

    And it has been rebutted here as applied to a petition that runs
    afoul of the settled rule that our jurisdiction is limited to the
    disposition of adversary proceedings.92
    D.       We Should Call for Notice and Adverse Briefing Even if
    Not Required to Do So
    ¶194     Even if adverseness were not a required component of
    our jurisdiction under the Utah Constitution, that would leave the
    question whether we should nonetheless order adversary briefing
    for prudential reasons. And I see little room for doubt on that
    question.
    ¶195     In resolving this case, the court is establishing a new
    standard of gender identity to be reflected as the designation of a
    person‘s sex on Utah birth certificates. In adopting this new
    standard, the court is crediting the interests and arguments of the

    There is no presumption that the legislature can delegate to our
    courts the power that has long belonged to the executive branch.
    We have an independent obligation to make sure that we are not
    exceeding the bounds of our jurisdiction. And any presumption of
    constitutionality that attaches to the statute has been rebutted in
    my view.

    See supra ¶ 103 n.44 (repudiating my recognition of the existence
    of interests and viewpoints belonging to groups unrepresented in
    the non-adversarial briefing before the court). And the court‘s
    new standard will control all future proceedings in our Utah
    courts and will bind the executive branch of our government (the
    Utah Office of Vital Records) going forward.93
    ¶196    Perhaps the majority‘s new standard is a good one on
    a policy level. It is certainly protective of one set of interests at
    stake—that of transgender persons who wish to have their
    government documents match their gender identity.94 But there
    are other interests on the table, like the interests of biological
    women in competing only with other biological women in sports
    (for scholarships, records, and awards), and the privacy and
    safety interests of those who enter high school locker rooms or
    safe-space shelters for abuse victims. The court is balancing away
    these and other contrary concerns without any notice to or voice
    from any party in a position to assert these adverse interests.95

    94  No one can seriously dispute the important role that birth
    certificates play in our society. A birth certificate ―records the

    passport, enroll in schools, get a driver‘s license, gain
    employment, or apply for other benefits.‖ Id. And the court‘s new
    standard will have indisputable effects in these and other
    applications. I cannot understand why we would choose to plow
    forward with the sweeping change adopted today without
    hearing from parties in a position to highlight concerns associated

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶197     None of the majority‘s historical precedents provides
    support for the court‘s decision to resolve this matter in the
    absence of any adversary briefing. In none of the majority‘s cited
    examples is a court balancing away adverse interests in a
    conclusive resolution of a disputed legal question. There is no
    precedent for this kind of ex parte resolution of a state ―adoption[],
    name change[], probate, [or] guardianship matter[],‖ In re

    2019 UT 40
    , ¶ 63, (Pearce, J. concurring), or
    of any federal proceeding involving a bankruptcy, receivership,
    pension or citizenship determination. In the mine run of those
    cases, the law is settled, no contrary interests are being foreclosed,
    and the court is not establishing a new legal standard. This case is
    different. And the majority has cited no salient support for its
    decision to exercise jurisdiction in a case like this one.
    ¶198     On a matter of this significance and magnitude, we
    should invite adversary briefing even if we are not required to do
    so. And if no adversary should appear, we should appoint an
    amicus to represent the adverse interests that are unrepresented
    in the briefing before us.
    ¶199     This is a path that many other courts have followed.
    The United States Supreme Court has invited an amicus to
    represent adverse interests dozens of times. See Katherine Shaw,
    Friends of the Court: Evaluating the Supreme Court's Amicus
    Invitations, 101 CORNELL L. REV. 1533, 1594 (2016). Often it does so
    in circumstances like those presented here, where there has been a
    ―lack of genuine adversary proceedings at any stage in [the]
    litigation,‖ and where the outcome ―could have far-reaching
    consequences.‖ Granville-Smith v. Granville-Smith,

    resolve this matter. But no court ever gave any notice of the right
    of any party to assert any interests on the merits of the question
    presented for our decision. And we have no briefing of that
    nature. Our court is making new policy in this sensitive field
    without any input from anyone who may be in a position to raise
    concerns about the establishment of a new standard of ―gender
    identity‖ for Utah birth certificates. This is surely unwise as a
    matter of prudential policy, even if it is not foreclosed as a matter
    of our jurisdiction.

    ¶200     Without adversary briefing, we are ill-equipped to
    establish a new concept of gender identity to be reflected on birth
    certificates in Utah. As judges on a court of law, we are in no
    position to analyze and weigh for ourselves the competing
    interests implicated by a decision of this magnitude. We do not
    represent a constituency of voters and we have no mechanism for
    asking legislative committees to elicit input from the broad range
    of public views on the matter. In the exercise of our appellate
    authority, we are entirely reliant on the adversary system. And it
    makes no sense for us to tread boldly into the territory of
    common-law decisionmaking in the absence of any adversary
    input—even if we had the power to do so in a case in which there
    is no adverse party.
    ¶201     This prudential course admittedly would introduce
    some additional ―delay‖ in an already long-pending matter. See
    supra ¶ 43 n.21 (raising this concern). But process matters. We
    could and should have dismissed this case on jurisdictional
    grounds very early on. That decision would have put the question
    presented back in the legislature‘s lap, where it belongs. And in
    all events, there is no basis for our court to be making new law on
    a matter of this magnitude in a non-adversarial proceeding.
    II. MERITS
    ¶202    The majority‘s decision is troubling even if we assume
    away the jurisdictional and prudential limits on our judicial
    power. Our power is limited in a second, important way. We are
    bound by the text of the law enacted by the legislature.
    ¶203     The governing text was enacted in 1975, when the
    legislature amended our longstanding Utah Vital Statistics Act. At
    that time, the legislature added a provision requiring the registrar
    of the Office of Vital Records to issue an amended birth certificate
    ―[w]henever a person born in this state has their name and/or sex
    change approved by an order of a court‖ upon presentation of a
    completed application and payment of a fee. 
    1975 Utah Laws 222
    .
    This provision has been recodified (in essentially identical terms)
    in Utah Code section 26-2-11.
    ¶204      The question presented goes to the meaning of the
    statutory reference to a person‘s ―sex‖ in this context. Everyone
    agrees that this term refers to a person‘s biological sex when the
    birth certificate is initially created. See supra ¶¶ 4 n.5; 90, 104. Here
    we are asked to decide whether the term ―sex‖ takes on a different
    meaning in the context of a ―change‖ to the same document.
    91
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶205      That question has a straightforward answer on the
    face of the statutory text. A statute that speaks only to the effect of
    an order for a change to a birth certificate sex designation cannot
    be read to be delegating common-law power to develop an
    evolved concept of ―gender identity.‖96 The reference to ―sex‖ in
    this statute is a reference to biological sex. That is the obvious
    sense of ―sex‖ that is in play in the initial sex designation on a
    birth certificate. And that same concept must be understood to be
    carried forward in a statute that states no separate standard for an
    order amending that same document.97 This follows both from the
    canon of consistent meaning and the presumption that a
    legislature does not ―alter the fundamental details of a regulatory
    scheme in vague terms or ancillary provisions—it does not . . .
    hide elephants in mouseholes.‖ Whitman v. Am. Trucking Ass’ns,
    
    531 U.S. 457
    , 468 (2001).
    ¶206    The statute thus leaves no room for the majority‘s
    evolved standard of a sex-designation based on the receipt of
    __________________________________________________________
    96 This is in fact the concept of ―sex‖ established by the
    majority as the law of this state. The court can insist that it is only
    deeming the ―sex‖ designation as a ―datum of legal status‖ and
    not ―argu[ing] that ‗sex‘ means ‗gender identity.‘‖ Supra ¶ 106
    n.48. But the reality remains: The ―datum of legal status‖ adopted
    by the court is one that equates a birth certificate sex designation
    with a person‘s gender identity under an evolved standard
    established by the court.
    97  Like the Chief Justice, I interpret the governing statute as
    envisioning a ―routine procedural‖ filing ―by which a birth
    certificate amendment may be effected.‖ Supra ¶ 123. And I view
    the statute as speaking to ―the kinds of birth certificate
    amendments subject to the statute.‖ Supra ¶ 123. Yet I see those
    premises as pointing in a different direction than that outlined by
    the Chief Justice.
    The statute may not prescribe a ―substantive standard‖ for the
    issuance of an order for an amendment to a birth certificate. Supra
    ¶ 123. But it does speak to the ―kind[]‖ of designation that is
    subject to amendment by court order. Supra ¶ 123. The operative
    concept or type of designation at issue is a biological sex
    designation—not a novel determination of gender identity. And
    in my view, that same kind of designation should be the one at
    play in any request for a court order to amend this vital record.

    treatment for gender transitioning or change. Nor does it yield
    any indication of an intent to delegate common-law policymaking
    power to the courts. I develop both points in greater detail below.
    A.       Plain Meaning
    ¶207     We have long expressed a commitment to the ―plain‖
    or ―ordinary‖ meaning of statutory language. See, e.g., Olsen v.
    Eagle Mountain City, 
    2011 UT 10
    , ¶ 9, 
    248 P.3d 465
    . This
    commitment is based on a host of good reasons, all rooted in our
    understanding of the rule of law. Only the plain language of the
    statute ―survived the constitutional process of bicameralism and
    presentment.‖ Graves v. N. E. Servs., Inc., 
    2015 UT 28
    , ¶ 67, 
    345 P.3d 619
    . And it is thus our responsibility to give voice to ―the
    policy judgment‖ reached by the political branches of our
    government—not to ―impos[e] our own will through the exercise
    of our limited judicial power.‖ Id. ¶ 70.
    ¶208     We can credit the plain or ordinary meaning of the
    language of our law only if we understand some nuances of our
    human language. And those nuances cut clearly in favor of a
    biological concept of ―sex‖ as that term is used in Utah Code
    section 26-2-11.
    ¶209     A starting point is the acknowledgement that the
    building blocks of human language are subject to ambiguity—a
    word can be understood to have one meaning in one setting and a
    different one in another. Another is the idea that our language is
    subject to evolution over time—words can take on new meanings
    through the process of ―linguistic drift.‖ These elements
    contribute to the ambiguity in the language of the law. But they
    by no means rob our language of all determinate meaning. And
    they do not open the door to any and all judicial ―interpretations‖
    of legal language.
    ¶210    Much of the law‘s ambiguity is ―eliminated by
    context.‖ Olsen, 
    2011 UT 10
    , ¶ 13 (quoting Deal v. U.S., 
    508 U.S. 129
    , 131–32 (1993)). Legal and linguistic context can even remove
    ambiguities arising from evolution in the meaning of a word over
    time. Think of the word ―sick‖—a term that traditionally was
    understood to refer to ill health, but more recently has morphed to
    include the idea of an impressive or risky move by an athlete. See
    State v. Rasabout, 
    2015 UT 72
    , ¶ 59, 
    356 P.3d 1258
     (Lee, A.C.J.,
    concurring) (noting this evolution in the use of this word).
    Historical uses of ―sick‖ would not readily be viewed in the latter
    sense; and a law that spoke to ―sick leave‖ for employees surely
    would be understood as addressed only to the former sense.
    93
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶211      These observations dictate a clear answer to the
    interpretive question presented in this case. The term ―sex‖ may
    arguably be in the process of linguistic drift. Increasingly, some
    people speak of ―sex‖ as a term referring not only to biology but
    also to gender identity. Others insist on a contrary view, holding
    fast to the idea that sex is and can only be a matter of biology.98
    ¶212     The clash of these two conceptions has triggered a bit
    of a culture war. As with so many points of conflict in our society
    today, the tension is heated. Each side advances its view with
    fervor and occasional furor—with the charge that the latter view
    ignores or overrides established science, or the criticism that the
    former position fails to afford dignity or inclusion to those whose
    identity is incompatible with their biological sex.
    ¶213   Fortunately, we are not called upon to mediate this (or
    any other) dimension of a culture war. We are asked only to
    decide the question whether the term ―sex‖ as used in a 1975
    statute governing the terms of a birth certificate can be
    understood as a reference to the concept of ―gender identity‖ that
    has evolved in recent years. The answer to that question is clear. It
    cannot. And any ambiguity is resolved on the basis of both the
    timing and the context of the 1975 statute.99
    ¶214   The statute in question was enacted in 1975. At that
    time, a reference to a person‘s ―sex‖ unambiguously was

    22, 2021) (defining sex as a classification based on biological
    characteristics and gender identity as a ―person's internal, deeply
    held sense of their gender‖).
    99 My analysis is focused on the meaning of a ―change‖ to the
    designation of a person‘s ―sex‖ on a birth certificate. This is the
    relevant legal and linguistic context of the statutory language—
    and the context that must be taken into account in discerning the
    ordinary meaning of the terms of the statute. The statute, after all,
    cannot possibly be read to require a court order as a legal
    precondition to a person‘s right to undergo this kind of ―sex
    change.‖ In contemplating an order for a ―sex change,‖ the statute
    is clearly speaking of a ―change‖ in the designation of a person‘s
    ―sex‖ on a birth certificate. And my analysis is thus focused on the
    meaning of that kind of ―sex change‖ in this legal context.

    construct tied to an individual person‘s identity. Only one of these
    dictionaries, in fact, refers to the more evolved concept of identity
    at all, and it does so in a definition of ―gender identity.‖101
    ¶215     The culture-war concern about the biological concept
    of ―sex‖ has thus arisen only in recent years. So any linguistic drift
    of this term had not developed at any time in which our
    legislature enacted law in this field. Neither the majority nor the
    petitioners have cited any authority to the contrary. And in fact at
    least one of the cases relied on extensively by the majority
    confirms my contrary conclusion. See Bostock v. Clayton Cnty., 
    140 S. Ct. 1731
    , 1739 (2020) (proceeding on the assumption that ―the
    term ‗sex‘ in 1964 referred to ‗status as either male or female [as]
    determined by reproductive biology‖ (alteration in original)); 
    id.
    at 1746–47 (openly stating that the court ―agree[d]‖ that a person‘s
    ―transgender status‖ is a ―distinct concept[] from sex‖).
    ¶216      The biological meaning of the term ―sex‖ here is
    reinforced by the legal and linguistic context of its use in this
    statute. The reference to the designation of a person‘s sex on a birth
    certificate can only be understood as a reference to biological sex.
    This is clear, first, as a matter of simple logic—a baby has no
    capacity for expression of gender identity, so only biological sex
    can be reflected on a birth certificate. But it is also clear as matter
    of the established use of this term in this legal setting. In the birth
    certificate setting, ―sex‖ is an unambiguous reference to biological
    sex, not gender identity.102
    use of the term ―sex‖ historically was understood to refer to
    gender identity—or receipt of treatment for gender transitioning
    or change.

    ¶217     The majority cites no contrary authority—indeed, it
    concedes the threshold point. See supra ¶¶ 4 n.5; 90, 104. And I can
    find no basis for viewing the designation of a person‘s ―sex‖ on a
    birth certificate as anything other than a reference to biological
    sex. There is thus no basis for any ambiguity in the meaning of the
    term ―sex‖ in the context of a birth certificate designation. The
    term, in this context, is plain. Any ambiguity is eliminated by
    context.
    ¶218    That leaves only the question whether the reference to
    a ―sex‖ designation on a birth certificate can be viewed to
    incorporate a different meaning when it comes to a ―change‖ to
    that designation. And again, the answer to that question is clear.
    The statute itself doesn‘t spell out an express standard for a court
    to issue an order approving a change to a birth certificate ―sex‖
    designation. But that speaks volumes. In a statutory scheme that
    governs both the original content of a birth certificate and later
    changes to that content, the reference to a ―change‖ to the original
    content cannot be viewed to alter the scope of the original content.
    The ―sex‖ designation in both instances is the same.
    ¶219    This was, in fact, the widespread understanding of the
    concept of a ―change‖ to birth certificate ―sex‖ designation at the
    time of the initial enactment of the controlling statute. In every
    single state with statutes allowing an amendment to a sex
    designation on a birth certificate in 1975 (there were only a few),
    literally all of them required a change to physiological
    manifestations of biological sex—sex-reassignment surgery.103

    birth certificate and the statutory reference to a ―change‖ to that
    designation. But it quickly abandons the connection (without
    acknowledging the active nature of its move).
    ¶221      The initial concession is the statement that the court
    ―believe[s] that, much like a sex designation made at birth, a
    change in sex designation should be accompanied by objective
    evidence.‖ Supra ¶ 105. So far, so good. Yet the very next sentence
    is the articulation of an entirely new concept of a change in the
    designation of a person‘s sex. After stating that it ―believe[s]‖ that
    the ―sex‖ designation on the original birth certificate is based on
    objective medical evidence, the court moves immediately to this:
    ―As a result, we hold that a petitioner must present, at the
    minimum, evidence of appropriate clinical care or treatment for
    gender transitioning or change, provided by a licensed medical
    professional.‖ Supra ¶ 105. But this is a linguistic non-sequitur.
    The court‘s new standard is by no means a ―result‖ of the
    biological concept of sex that controls the original birth certificate
    designation. This is clear from the fact that the court nowhere
    attempts to tie its standard of ―gender identity‖ to a definition of
    ―sex.‖104 In formulating its new standard, the majority is not
    invoking an ordinary or legal definition of ―sex‖—and certainly
    not a definition from the time period in which the statute in
    question was enacted. It is just asserting that there is ―gap‖ in the
    statute, and leaping from that gap to the prerogative of
    establishing a novel meaning of the words that do appear in the
    statute. See supra ¶ 50.
    ¶222     There is no ―gap‖ that is not eliminated by the context
    of the statute in which the term ―sex‖ appears. A statute that
    refers only elliptically to an order for a ―change‖ to the
    designation of a person‘s ―sex‖ on a birth certificate must be
    viewed to refer to the same concept of sex established at the time
    of a child‘s birth.
    ¶223     A basis for a change in that designation could be
    established upon discovery of a mistake in the biological sex

    104 The court does refer to a definition of ―sex‖ in a different
    legal setting—in a statute prohibiting discrimination on the basis
    of ―sex‖ in housing. See supra ¶ 4 n.5. But it does not adopt the
    housing discrimination notion of ―sex,‖ or even its separate
    concept of ―gender identity.‖ See infra ¶ 226 (discussing this point

    designation made at the time of a child‘s birth, or a showing that
    the biological features of an intersex person have developed
    differently than expected at birth. It also might be met where a
    person can demonstrate that the biological indicators of sex have
    been altered, as by sex-reassignment surgery.105 But the statutory
    basis for a change in a birth certificate ―sex‖ designation cannot be
    established on the mere basis of a change in ―gender identity‖
    evidenced only by ―appropriate clinical care or treatment‖ for
    gender transitioning or change. This is not our law. Gender
    identity is not sex—at least not in the birth certificate context.106
    __________________________________________________________
    105 Such surgery conceivably could establish a basis for a
    ―change‖ to a person‘s ―sex‖ that would sustain a birth certificate
    amendment. I stop short of giving a conclusive answer, however,
    because this case comes before us in a non-adversary posture and
    this question is not presented for our decision in any event.
    If and when our law adopts a standard along these lines, that
    could require us to address some of the line-drawing questions
    highlighted by the majority. Supra ¶ 91 (citing an ―array of
    surgical options‖ and a disagreement among the courts as to what
    might qualify as ―sex-reassignment surgery‖). But I am not
    advancing a proposed standard for ―sex change‖ based on sex-
    reassignment surgery. And the concern about line-drawing is at
    least as clearly implicated by a standard requiring courts to decide
    (without adversary input) whether a petitioner is seeking
    ―appropriate clinical care or treatment for gender transitioning or
    change.‖ Supra ¶ 105.
    106  The majority concedes that the sex determination on a birth
    certificate is ―generally determined by an external ‗anatomical
    examination,‘ not by an examination of the individual‘s
    chromosomal makeup.‖ Supra ¶ 88. It also notes, however, that
    ―sex chromosomes are immutable‖ and cannot be altered by
    ―therapy, treatment, or procedure.‖ Supra ¶ 88. And with that in
    mind, the court insists that the legislature ―could not have
    intended to include consideration of sex chromosomes in its
    conception of ‗sex‘ in a statute regarding name and sex change.‖
    Supra ¶ 88. On that basis, the court then proceeds to assert that
    ―any definition of ‗biological sex‘‖ must somehow ―ultimately fail
    in this context.‖ Supra ¶ 89 n.39. Yet that does not follow. The
    court has identified a basis for limiting the basis for an

    ¶224   In the paragraphs below I develop further support for
    this understanding in the canon of consistent meaning and the
    presumption that legislatures ―don‘t hide elephants in
    mouseholes.‖
    1.       Consistent Meaning
    ¶225    The consistent meaning canon says that a term used in
    one sense in a body of law is ―presumed to bear the same
    meaning‖ elsewhere. ANTONIN SCALIA & BRYAN A. GARNER,
    READING LAW: THE INTERPRETATION OF LEGAL TEXTS 170 (2012).
    The presumption is by no means irrebuttable. When context
    indicates, the same term can be understood to be used in two
    different ways in the same body of law. See 
    id.
     at 172–73. Yet
    context can also reinforce the presumption, and the canon of
    the initial designation—physical observation. It has not, however,
    identified any reason to call that basis for the sex designation into
    question.
    The majority goes off on some further tangents that miss this
    nuance and misunderstand my position. In defending its view,
    the court rejects as ―absurd[]‖ the notion that ―biological sex‖
    might ―includ[e] the immutable genetic makeup of an
    individual.‖ Supra ¶ 89. And it then argues at some length that a
    birth certificate sex designation must therefore be a ―legal
    classification‖ and not a ―biological‖ one, supra ¶ 89, and even
    that ―any definition of ‗biological sex‘‖ must accordingly ―fail in
    this context.‖ Supra ¶ 89 n.39. I find this puzzling. No one has
    argued that the biological sex designation on a birth certificate
    should be based on a chromosomal test. The question is not
    presented, and I have not advanced this position. I have argued
    instead that the basis for an amendment to a birth certificate sex
    designation should be focused on the basis for the initial sex
    designation—physical observation of anatomical manifestations
    of sex. That is a legal classification based on a biological
    classification. And there is nothing absurd about it.
    The question presented goes not to the basis for the biological
    determination (which is also the legal determination), but to
    whether a statute that makes clear reference to that determination
    can be viewed as compatible with a determination of a person‘s
    gender identity. It cannot.
    101
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    consistent usage is strongest where, as here, the same term is used
    in closely connected ways.107
    ¶226      The connection here is unmistakable. It follows from
    the fact that the statute fails to speak independently of a standard
    for a ―change‖ in the designation of a person‘s ―sex‖—the basis
    for such an order is simply presumed. In this setting, there is an
    implicit assumption that the ―sex‖ designation subject to
    ―change‖ is the same sort of designation being made in the first
    place. Where all agree that the original ―sex‖ designation on a
    birth certificate is an objective determination based on observation
    of physical characteristics, the statutory reference to an order for
    an amendment to the same designation on the same document must
    be understood in the same way.
    ¶227     The majority‘s contrary conclusion is rooted in part in
    its consideration of an entirely distinct body of law—in a
    definition of ―sex‖ in the Utah Fair Housing Act. See supra ¶ 107
    n.50 (stating that the court is looking to the statute ―for
    guidance‖). Because that statute prohibits discrimination in
    housing on the basis of ―sex,‖ and says that ―‗sex‘ means gender,‖
    not ―gender means sex,‖ the court concludes that ―the legislature,
    in its wisdom, conferred broader meaning on the term ‗sex.‘‖
    Supra ¶ 4 n.5 (quoting UTAH CODE § 57-21-2(22)). But the court
    identifies no basis for extending the Fair Housing Act definition of
    ―sex‖ to the use of that term in the context of birth certificate
    amendments. It nowhere explains, moreover, how it can get its
    particular ―broader meaning‖—―appropriate care or treatment for
    gender transitioning or change‖—out of the Fair Housing Act.
    Ultimately, the Fair Housing Act definitions cut squarely against
    the majority‘s position.
    ¶228     The case law makes clear that the consistent meaning
    presumption is particularly sensitive to context. The presumption
    ―can hardly be said to apply across the whole corpus juris.‖ SCALIA

    distinct from each other, ―[t]he mere fact that‖ the same words are
    used in each area of law ―is not a sufficient reason‖ for treating
    the meaning established in one body of law ―as authoritative on
    the construction of another statute.‖ Rupert Cross, Precedent in
    English Law 192 (1961)Id. at 172–73 (citation omitted). The further
    removed the two bodies of law are from each other (in subject and
    time of enactment), the weaker the presumption of consistent
    meaning. Id. at 173. This defeats the majority‘s reliance on the Fair
    Housing Act definition of ―sex.‖ The cited definition in the Fair
    Housing Act was enacted in 1989—fourteen years removed from
    the statute at issue here. Housing discrimination, moreover, bears
    little connection to birth certificate amendments. The clearly closer
    connection is to the use of ―sex‖ in the initial formation of the
    birth certificate. For these reasons, the Fair Housing Act definition
    is hardly supportive of the majority‘s view.
    ¶229     The majority never explains, moreover, how it gets
    from the Fair Housing Act‘s notion that ―sex means gender‖ to the
    idea that ―sex means care or treatment for gender transitioning or
    change.‖ It does not—even under the Fair Housing Act. The cited
    definition of ―sex‖ is truncated in the quote in the majority
    opinion. Under the housing statute, ―‗sex‘ means gender and
    includes pregnancy, childbirth, and disabilities related to pregnancy and
    childbirth.‖ UTAH CODE § 57-21-2(22) (emphasis added). The
    italicized language is significant. It indicates that even in the Fair
    Housing Act, the legislature isn‘t using ―sex‖ (or ―gender‖) to
    refer to care or treatment for gender transitioning or change, but
    to aspects of sex that are related to the biological indicators of sex
    (like pregnancy and childbirth). This conclusion is reinforced by
    the Fair Housing Act‘s separate prohibition of discrimination
    based on ―gender identity,‖ and the separate definition of that
    term as incorporating ―the meaning provided in the Diagnostic
    and Statistical Manual (DSM-5),‖ which may be established by
    evidence of ―medical history, care or treatment of the gender
    identity, consistent and uniform assertion of the gender identity,
    or other evidence that the gender identity is sincerely held, part of
    a person‘s core identity, and not being asserted for an improper
    purpose.” Id. § 57-21-2(16).
    ¶230      This is telling. Perhaps the Fair Housing Act
    definitions in some way suggest that the legislature ―conferred
    broader meaning to the term ‗sex‘‖ than the term would bear in
    other contexts. But there is no reason to view the housing
    definition to apply in the birth certificate context. And the housing
    103
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    definitions, if anything, confirm that ―sex,‖ however broad, does
    not mean ―care or treatment for gender transitioning or change.‖
    ¶231     The majority, in all events, does not ultimately apply
    the Fair Housing Act definition of ―gender identity.‖ It rejects that
    statute‘s requirement of proof that gender identity is ―sincerely
    held‖ and ―part of a person‘s core identity.‖ Supra ¶ 107. And the
    court turns instead to standards of gender identity applied by the
    Social Security Administration, the State Department, and courts
    in other states.108 See supra ¶¶ 108–10.
    ¶232     The majority‘s standard, moreover, does not even
    align with the standards promulgated by the Social Security
    Administration and State Department or with many of the cited
    standards adopted in other states.109 The federal standards require

    108 The majority also refers to orders entered in twelve cases
    filed in our Utah district courts, asserting that such orders ―show‖
    that ―an objective medical standard‖ is ―workable.‖ Supra ¶ 111.
    But the cited orders can hardly be viewed as representative of the
    standards applied by our Utah district courts. They are just a
    sampling of orders submitted by the petitioners in support of
    their proposed standard. The cited Utah orders, moreover, are not
    supportive of the majority‘s approach in any event. They do not
    suggest that our district courts have provided for an amendment
    to a sex designation on a birth certificate based on proof of
    ―appropriate clinical care or treatment for gender transition or
    change.‖ Several of them refer to completed surgery or ongoing
    hormone therapy, neither of which is required by the majority‘s
    new standard. See In re Davis, No. 173900047, at 2 (Utah Dist. Ct.
    Second Dist. Mar. 27, 2017) (petitioner had undergone irreversible

    109 The State Department also recognizes a difference between
    an individual who is still undergoing transition, and one who has

    112 The Chief Justice stops short of endorsing the majority‘s

    Chief Justice proposes to require only proof of ―proper cause‖—a
    standard (imported from the name-change setting) that forecloses
    petitions filed ―for a wrongful or fraudulent purpose.‖ See supra
    ¶ 131. I would not equate the concepts of name-change and sex-
    change for reasons explained below. See infra ¶¶ 270–80. But I also
    see problems with the Chief Justice‘s proposed standard on its
    own terms.
    ―Proper cause‖ is not a substantive standard. It does not define
    the relevant concept of a designation of a person‘s ―sex.‖ It is
    simply the articulation of a negative basis for rejecting a petition
    filed for improper reasons. And without some substantive
    standard or articulation of the operative concept of the
    designation of a person‘s ―sex‖ on a birth certificate, we will be
    left with nothing but unbridled judicial discretion on what is
    ―proper.‖ See supra ¶ 132 (suggesting the need to let the

    2.        Elephants in Mouseholes
    ¶234    Even if there were some ambiguity as to the meaning
    of ―sex‖ in the birth certificate context, the ambiguity could not
    properly be viewed as a basis for this court to establish an evolved
    concept of ―gender identity‖ for birth certificate amendments.
    Any such ambiguity cuts the other way. A legislature that sees no
    reason to speak to the ―standard‖ for issuance of an order for
    amendment of the sex designation on a birth certificate is not
    delegating policymaking power to the courts on a matter with the
    potential for momentous implications. It is presuming that the law
    is not breaking any new ground, and carrying forward the settled,
    static meaning of a ―sex‖ designation on a birth certificate.

    the presumption that legislatures ―do[] not . . . hide elephants in
    mouseholes.‖ Rutherford v. Talisker, Canyons Fin., Co., LLC, 
    2019 UT 27
    , ¶ 53, 
    445 P.3d 474
     (alteration in original) (quoting Whitman
    v. Am. Trucking Ass’ns, 
    531 U.S. 457
    , 468 (2001)). This canon is
    premised on the understanding that legislative bodies do not
    ―alter the fundamental details‖ of our law ―in vague terms or
    ancillary provisions.‖ Whitman, 
    531 U.S. at 468
    . The canon has
    been applied as the basis for this court‘s reluctance to find that our
    legislature altered the common law doctrine of primary
    assumption of risk in a statute that did not explicitly use the term
    ―negligence‖ in its regulation of the liability of ski area operators.
    Rutherford, 
    2019 UT 27
    , ¶ 53. And in the federal realm, the courts
    have invoked the canon as the basis for the conclusion that the
    Food Drug and Cosmetic Act did not delegate to the Food and
    Drug Administration (FDA) the power to regulate cigarettes and
    nicotine as a ―drug‖ in the absence of a clear statement of such
    intention, see Food & Drug Admin. v. Brown & Williamson Tobacco
    Corp., 
    529 U.S. 120
    , 159–61 (2000), and that the Controlled
    establish proper cause . . . to develop over time, as district court
    judges exercise . . . broad discretion‖).
    The ―proper cause‖ standard thus kicks the can down the road
    on what should count as a salient showing of a change in a
    person‘s ―sex‖ as reflected on a birth certificate. In this sense, it is
    an invitation for judicial policymaking on a case-by-case basis.
    And it is accordingly no more defensible than the standard
    established by the majority.

    Substances Act did not delegate to the Attorney General ―broad
    and unusual authority‖ to prohibit physicians from prescribing
    drugs for use in physician-assisted suicide ―through an implicit
    delegation‖ in the statute‘s ―registration provision.‖ Gonzales v.
    Oregon, 
    546 U.S. 243
    , 267 (2006).
    ¶236     These principles are applicable here. The delegation of
    common-law power to set a new, evolving standard for the
    issuance of an order for amendment of the sex designation on a
    birth certificate is a big deal. Because such sex designations have
    sweeping effects on our society, it is highly unlikely that the
    legislature would have made an ―implicit delegation‖ of such
    common law power. This is quite an elephant. And the statute
    governing only the effect of such an order is a tiny mousehole.
    ¶237     Consider the sweeping nature of the majority‘s
    holding. In establishing a new standard for an order for a sex
    change designation on a birth certificate, the court cites a Fair
    Housing Act definition of ―gender identity,‖ standards
    implemented in recent years by the Social Security Administration
    and the United States State Department, decisions handed down
    in the past few years by the appellate courts of states governed by
    laws distinct from our Utah law (none of them involving a statute
    phrased as ours is), and a few unpublished orders of our Utah
    district courts. Supra ¶¶ 108–11. None of these sources defines a
    change in a ―sex‖ designation on a birth certificate in the manner
    the court does. So the majority is not citing these authorities as
    somehow establishing the meaning of a change in a sex
    designation on a birth certificate as those terms are used in our
    Utah statute. It is simply referring to them in the course of an
    exercise of its own asserted common-law authority.
    ¶238    The 1975 Utah Legislature was not delegating such
    sweeping policymaking power to the courts. It was not hiding
    such an enormous elephant in the obscure mousehole of a
    provision governing only the effect of an order for an amendment
    to the sex designation on a birth certificate.
    ¶239      The statute applies ―[w]hen a person born in this state
    has a . . . sex change approved by an order of a Utah district
    court.‖ UTAH CODE § 26-2-11. And this statutory mousehole
    implies the anticipation of a mere mouse—a straightforward
    showing of a person‘s ―sex change‖ that can be made in the same
    way the initial sex designation was made. If the initial sex
    designation on the birth certificate is based on ―biological sex as
    evidenced by chromosomes, genitals, and other physical
    107
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    characteristics,‖ then the ―change‖ to that designation should be
    understood to carry forward that same standard.
    ¶240      As noted above, such a showing could be made
    through simple, straightforward evidence—proof that the initial
    designation was made initially in error, that an ―intersex‖
    person‘s sex designation has been proven wrong over time, or
    that the biological markers of sex have been altered by medical
    interventions like sex-reassignment surgery. A change in the sex
    designation on a birth certificate on these grounds fits within the
    statutory understanding of the ―sex‖ designation on a birth
    certificate. It would thus be a ―mouse.‖ But the changes endorsed
    by the court today are another matter. They are an enormous
    elephant that could not have been contemplated by the Utah
    Legislature in 1975.
    B.       Delegation of Common-Law Policymaking Power?
    ¶241    The 1975 statute may not expressly articulate a
    ―substantive standard‖ for the entry of a birth certificate
    amendment order. See supra ¶ 54. But it does speak to the type or
    ―kind[]‖ of birth certificate designation at issue. See supra
    ¶ 123.And any supposed ―gap‖ in the statute cannot be taken as a
    delegation of common-law power for the courts to update the law
    in accordance with our evolved views of gender identity.
    ¶242     The majority seeks to root its contrary conclusion in
    three grounds: (1) the assertion that our courts retain broad
    common-law power to fill in ―gaps‖ in statutes except where the
    exercise of such power ―conflicts with statutory guidance,‖ supra
    ¶ 53; (2) the notion that the reference to ―sex change‖ is
    ―combined‖ with ―name change,‖ which purportedly is a
    delegation of authority to develop a common-law of sex change,
    supra ¶ 50; and (3) the observation that the registrar is bound to
    amend birth certificates in response to orders of ―a court of
    competent jurisdiction of another state or a province of
    Canada‖—a fact the court takes as an indication that the
    legislature has prescribed no standard of sex at all, but has left the
    matter to the courts (whether in Utah or elsewhere). Supra ¶ 78
    (emphasis omitted).
    ¶243     All of these premises collapse on closer scrutiny. And
    the majority‘s analysis is undermined not only by the cases it cites,
    but also by the canon of constitutional avoidance (under the non-
    delegation doctrine).

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶244    The court‘s first premise is built on the notion of a
    ―gap‖ in a statute that speaks only to the effect of a court order.
    But the supposed gap cuts against the majority‘s position for
    reasons set forth above—the gap should be filled in light of the
    established meaning of ―sex‖ in the birth certificate context, under
    the canon of consistent meaning and the ―elephants in
    mouseholes‖ canon.
    ¶245    The court‘s notion of its ―gap-filling‖ role is a novel
    one in any event. It finds no support in, and is in fact undermined
    by, the Utah cases cited in the majority opinion. 113
    ¶246    Our Utah Code and case law concededly recognize
    the residual authority of the common law. By statute, our
    legislature long ago adopted ―[t]he common law of England so far
    as it is not repugnant to, or in conflict with, the constitution or
    laws of the United States, or the constitution or 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.‖ UTAH CODE § 68-3-1. And our opinions have
    reinforced that the common law retains its power ―[i]n the absence
    of applicable constitutional or statutory authority.‖ Spackman ex

    2000 UT 87
    ,
    ¶ 20, 
    16 P.3d 533
    .
    ¶247      But the ―common law‖ is not an invitation for courts
    to search for gaps in the law to fill in with judicial policy. It is an
    established body of case law, identifying a range of rights and
    duties residing outside the positive law set forth in statutes and
    constitutions. See S. Pac. Co. v. Jensen, 
    244 U.S. 205
    , 222 (1917)
    (Holmes, J., dissenting) (―The common law is not a brooding
    omnipresence in the sky, but the articulate voice of some
    sovereign or quasi sovereign that can be identified.‖); Common
    Law, BLACK‘S LAW DICTIONARY (11th ed. 2019) (―The body of law
    derived from judicial decisions, rather than from statutes or
    constitutions.‖). The rights and duties established in that body of
    case law of course are subject to evolution and development over
    __________________________________________________________
    113 In other jurisdictions, the case law may occasionally assert a
    prerogative of an ―inherent equity power of courts of general
    jurisdiction‖ that is sufficiently sweeping to encompass the
    majority‘s approach. See supra ¶ 56 (quoting In re Change of Birth
    Certificate, 
    22 N.E.3d 707
    , 709 (Ind. Ct. App. 2014)). But our Utah

    time. But it is a body of law, not a basis for freestanding judicial
    policy.
    ¶248     This point is established by the majority‘s own
    precedent. Absent legislative abrogation, existing bodies of
    common law ―retain‖ their ―authority.‖ Supra ¶ 50 n.22 (quoting
    Williamson v. Farrell, 
    2019 UT App 123
    , ¶ 17, 
    447 P.3d 131
    ). And
    we do not lightly presume that the legislature meant to abolish
    established bodies of common law by legislation. Supra ¶ 50 n.22
    (citing Anderson v. Bell, 
    2010 UT 47
    , ¶ 16 n.5, 
    234 P.3d 1147
    ). But
    those principles presuppose the existence of established bodies of
    common law to be retained, or to avoid abolishing. If and when
    there is no existing body of common law, there is no basis for the
    conclusion that the legislature meant to delegate the power to
    create it out of whole cloth.
    ¶249      Our decision in Rawcliffe v. Anciaux, 
    2017 UT 72
    , 
    416 P.3d 362
    , is not to the contrary. There we simply held that the
    common law may ―assist[] in defining the scope of‖ common-law
    terms used in statutes. Id. ¶ 14. We did not hold that the only limit
    on our exercise of common-law power is that it not directly
    ―conflict[] with‖ a governing statute. Supra ¶ 53.
    ¶250     There are established bodies of common law on a
    wide range of subjects. The first-year law student‘s curriculum is
    focused on some of these subject areas—on property, contract,
    and tort law, and the ―common law‖ of crimes (though the latter
    is completely abolished in Utah, see UTAH CODE § 76-1-105). That
    list is by no means exhaustive. Another prime example is the law
    of remedies—a body of case law setting forth background
    standards and principles for damages and injunctive relief to be
    awarded across a range of claims.
    ¶251     In these fields, a gap in a statute may be taken as a
    reservation of retained common law power. But the same does not
    hold in every field of law. Some fields are purely statutory or
    administrative. There is no common law, for example, of
    hazardous waste permits, or hunting licenses, or Medicare. And
    there is thus no ―retained‖ common law to fill in ―gaps‖ in these
    fields. If the legislature leaves a gap in these areas, it must be
    filled in by reference to the language and structure of the statute—
    not by the invention of some new body of ―common law.‖
    ¶252   This principle is established by our decision in
    Mariemont Corp. v. White City Water Improvement Dist., 
    958 P.2d 222
     (Utah 1998). There we confronted a ―gap‖ in a statute

    filing of a petition by ―a majority of the real property owners‖ in a
    particular territory, id. at 223, but did not speak to ―whether
    names [could] be added to or removed from withdrawal
    petitions‖ after they had been filed. Id. at 226. Despite the gap, we
    emphasized the need to base our decision on the ―language‖ and
    structure of the statute and an ―attempt to harmonize the various
    provisions‖ of the statute. Id. at 227. And we openly repudiated
    the idea of a court ―fashion[ing] a statutory rule out of whole cloth
    without having any idea of the legislature‘s intentions.‖ Id.
    ¶253    The court‘s new standard for designation of a person‘s
    ―sex‖ on a birth certificate is of the ―whole cloth‖ variety. 114 There
    is no common law that governs this field. And there is no basis for
    the majority‘s assertion of common-law power.
    ¶254   The court‘s cited cases are not to the contrary. They
    undermine the majority‘s approach and support my position.
    Spackman ex rel. Spackman v. Board of Education
    ¶255     The court did not invoke the ―common law‖ in
    Spackman as a matter of filling in a gap in our state constitutional
    law—in the sense of an exercise of power to make new law as we
    best saw fit. In establishing standards for damages remedies for
    constitutional violations, we expressly held that ―a court‘s
    authority to do so arises from the common law‖ of remedies.
    Spackman, 
    2000 UT 87
    , ¶ 20. We thus cited provisions from the
    Restatement (Second) of Torts and established cases on the
    common law of remedies. 
    Id.
     And we nowhere indicated that a

    114 The majority broadly disclaims that it is making such a
    move. See supra ¶ 53. But it also fails to identify any basis for its
    new standard in the language of the statute or in any body of
    common-law. And its decision is thus by definition ―out of whole
    cloth‖—the cloth of a new court-made standard.
    A threshold element of the court‘s new standard is borrowed
    from the common-law of name changes. See supra ¶ 18 (requiring
    proof that sex change petition is not for a ―wrongful or fraudulent
    purpose‖). But the core standard of ―gender identity‖ as ―sex‖ is
    rooted purely in the court‘s own analysis of policy considerations.
    This standard bears no relation to any element of a common-law
    name-change proceeding. And the court has identified no basis
    for its authority to establish such a standard.

    perceived ―gap‖ in the law was an invitation for us to make pure

    for constitutional remedies by applying and extending a
    traditional body of common law.
    Rawcliffe v. Anciaux
    ¶256     Rawcliffe does not support the assertion of judicial
    power to inject new judicial policy into a statutory scheme so long
    as it does not directly ―conflict[] with‖ enacted statutes. Supra
    ¶ 53. The cited language is taken out of context. And the context
    undermines the majority‘s approach and reinforces my position.
    ¶257      The statute at issue in Rawcliffe ―codified . . . common
    law duties‖ of corporate officers and directors set forth in ―our
    precedent.‖ Rawcliffe, 
    2017 UT 72
    , ¶ 14. Because the statute itself
    did not define the duties incorporated from the common law, our
    Rawcliffe decision followed the presumption that statutes that
    borrow common-law terms of art are understood to carry forward
    ―the legal tradition and meaning‖ of those terms ―accumulated‖
    in historical ―practice‖ in the case law. 
    Id.

    Herbert, 
    2012 UT 44
    , ¶ 31, 
    284 P.3d 647
    ). In that setting, we held
    that the meaning borrowed from the common law could not be
    accepted if it ―conflict[s] with‖ the terms of the statute. 
    Id.
    ¶258    In so stating, we did not establish the power of a court
    to formulate a brand new body of common law aimed at updating
    or expanding the reach of a statute. We did not overrule the
    proscription of a court ―fashion[ing] a statutory rule out of whole
    cloth without having any idea of the legislature‘s intentions.‖

    Cox v. Laycock
    ¶259       This is also clear from the Cox v. Laycock decision. In
    that case we were interpreting a provision of the Election Code
    that lacked a provision ―describ[ing] how to fill a candidate
    vacancy in the case of an annulled primary election.‖ Cox v.
    Laycock, 
    2015 UT 20
    , ¶ 41, 
    345 P.3d 689
    . Despite this gap, we did
    not fill it on the basis of our judicial policy preferences, or suggest
    that there was a basis for doing so in some sort of ―common law‖
    of election vacancy filling. We simply ―analyze[d] the act in its
    entirety‖ and sought to ―harmonize its provisions in accordance
    with the legislative intent and purpose.‖ Id. ¶ 42 (quoting

    ¶260     The Cox decision thus further undermines the

    would not be fashioning a new standard of ―sex‖ based on our
    own ―common law‖ policy preferences; we would be
    harmonizing the law by interpreting the statutory reference to an
    order for an amendment to a ―sex‖ designation in harmony with
    the way the sex designation is made on the birth certificate in the
    first instance.
    Whyte v. Blair
    ¶261     The majority cites Whyte v. Blair as a supposed
    example of our court ―inject[ing] meaning‖ into statutes under
    our independent power to make common law policy. Supra ¶ 52.
    But the Whyte case does not support the majority‘s approach.
    Again, it contradicts it.
    ¶262     The statute at issue in Whyte abrogated a longstanding
    statutory prohibition of ―common law marriage‖ in Utah. 
    885 P.2d 791
    , 793 (Utah 1994). It thus authorized our courts to enter
    orders recognizing a ―marriage . . . not solemnized‖ formally
    under the code. UTAH CODE § 30-1-4.5. And this court interpreted
    the statute to incorporate (at least in part) settled ―common law‖
    standards for establishing an unsolemnized marriage. 885 P.2d at
    794.
    ¶263    Our analysis in Whyte was not the assertion of
    independent policymaking power of the court. We were not
    formulating a new standard of ―common law marriage,‖ or
    prescribing our own view of ideal ―factors‖ for the determination
    of person‘s marital status. We were interpreting a statute that
    incorporated the language of settled common law—and that in
    fact was introduced in the legislature ―as a common law marriage
    provision.‖ Id. at 793. The statute in question was interpreted as a
    ―codification of common law marriage principles.‖ Id. And we
    accordingly interpreted it as such.
    ¶264     The statute in question made broad reference to the
    notion of a ―marriage‖ that was not ―solemnized‖ under Utah
    Code section 30-1-4.5. It also incorporated factors long considered
    in the common law case law—capacity to give consent,
    cohabitation, mutual assumption of marital rights and duties, and
    reputation as husband and wife. UTAH CODE § 30-1-4.5(1). The
    majority is thus wrong to assert that ―none‖ of the common law
    factors cited in Whyte ―appear in‖ the governing statute. Supra
    ¶ 52. And in any event, Whyte is not a case in which the court was
    asserting the power to create a new common law standard. To the
    113
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    contrary, we were interpreting a statutory ―codification‖ of an
    established body of law as the adoption of established standards.
    Anderson v. Bell
    ¶265     The majority cites Anderson v. Bell for the proposition
    that our common-law authority neither depends on nor is easily
    limited by statutes. Supra ¶ 50 n.22. That may be true, but it‘s
    irrelevant to defining the scope of our power to establish new
    fields of common law.
    ¶266    Anderson establishes that not ―every instance that a
    statutory scheme and the common law converge . . . necessarily
    mean[s] the legislature has abolished the common law.‖ 
    2010 UT 47
    , ¶ 16 n.5, 
    234 P.3d 1147
    , superseded by statute on other grounds,
    UTAH CODE § 20A-9-502. When a statutory definition ―mirrors‖ a
    common law definition, Anderson endorses a presumption that the
    statute embraced the common law definition. Id. ¶ 16 & n.5. In
    Anderson, the court concluded that the statutory definition of
    ―signature‖ mirrored the common law definition of that term.
    And it thus interpreted the statute to carry forward the common
    law definition. Id. ¶ 16.
    ¶267    That analysis presupposes the existence of a field of
    ―common law.‖ And a case defining the relationship between the
    common law and statutory definitions says little about the extent
    of our common law powers. Much less does it show that a
    statutory ambiguity can create common law powers. To the
    contrary, Anderson instructs courts on how to interpret a statute
    that adopts a common-law definition.
    Williamson v. Farrell
    ¶268    The same goes for the court of appeals‘ analysis in
    Williamson v. Farrell. In applying a set of standards for the
    disposition of declaratory judgment actions, the court of appeals
    admittedly was applying ―four ‗threshold elements‘ for
    declaratory judgment actions‖ that did not ―appear anywhere‖ in
    the Utah Declaratory Judgment Act. 
    2019 UT App 123
    , ¶ 17, 
    447 P.3d 131
    . But the court of appeals was not prescribing those
    factors anew, out of whole cloth. It was observing that these
    factors were deeply embedded in a body of common law case law,
    and interpreting a statute that authorized ―declaratory
    judgments‖ but did not ―contain provisions setting forth the
    specific elements of a proper declaratory judgment claim.‖ Id.

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶269    This bears little relation to the majority‘s analysis in
    this case. Here we are not dealing with a statute that incorporates
    a term that is transplanted from the common law. We are
    presented with a statute that speaks of a change in a ―sex‖
    determination on a birth certificate—a matter that has never had
    any common law meaning. And that forecloses the majority‘s
    reliance on any supposed common law power, under Williamson
    and under all of the other cases it relies on.
    2.       Combination with Name Change
    ¶270     The majority seeks to avoid the above problems by
    noting that the birth certificate statute ―combine[s]‖ together the
    notion of an amendment to a ―sex‖ designation on a birth
    certificate with that of a ―name change‖ amendment to the same
    document. Supra ¶ 50. Because there is an established body of case
    law that was incorporated into our statutory proceedings for a
    ―name change‖ in Utah, the court asserts that the court must have
    been implicitly delegating to us the common law power to
    formulate a new common law standard for a birth certificate ―sex
    change.‖ Supra ¶¶ 50–51 (asserting that because the legislature
    ―knowingly and purposefully combined name and sex changes
    together‖, there is a basis for our ―common-law authority‖ to
    formulate a new standard not prescribed by the legislature).115
    __________________________________________________________
    115 The Chief Justice seeks to draw a different inference from
    the fact that ―the terms ‗sex change‘ and ‗name change‘ are
    bundled together‖ in the statute. Supra ¶ 124. While recognizing
    that these forms of amendment are ―different . . . both in

    parallel structure of the statute can be viewed to dictate the
    application of a name-change standard to adjudication of a sex-
    change petition.
    The designation of a person‘s name is different from the
    designation of a person‘s sex. And the threshold question on a
    petition to change either designation is whether the petition is
    addressed to the type or ―kind[] of birth certificate amendment[]
    subject to the statute.‖ Supra ¶ 123. A name-change amendment is
    thus available only if it involves a change to a person‘s ―name,‖

    ¶271      This does not follow from the cases cited by the
    majority. Those cases, in fact, cut against its analysis.
    ¶272      We have certainly stated that ―a word or phrase [that]
    is transplanted from another legal source . . . brings the old soil
    with it.‖ Supra ¶ 50 (quoting Maxfield, 
    2012 UT 44
    , ¶ 31,. And the
    birth certificate statute does borrow some language from the
    common law—in the reference to an amendment to the birth
    certificate under an order for a ―name change.‖ That phrase has
    common law meaning. And our case law quite properly has
    interpreted the Utah Code to have imported the common law
    standard for a ―name change‖ proceeding under our statutes. See
    In re Porter, 
    2001 UT 70
    , ¶ 8, 
    31 P.3d 519
    ; In re Cruchelow, 
    926 P.2d 833
    , 834 (Utah 1996). It in no way follows, however, that ―[w]hen
    the legislature transplanted‖ both ―name change‖ and ―sex
    change‖ in the same statute, ―it statutorily planted both ‗sex
    change‘ and ‗name change‘ in the latter‘s ‗old soil,‘‖ much less
    that it meant for us to establish a ―common law‖ standard for ―sex
    change.‖ Supra ¶ 50.
    ¶273     The court‘s syllogism is oversimplified. Our Maxfield
    opinion does not say that the use of one term imported from the
    common law imbues the entire statute with common-law
    meaning. In fact it draws a distinction between a ―word or
    phrase‖ borrowed from ―the common law‖ and a term imported
    from ―legislation.‖ Maxfield, 
    2012 UT 44
    , ¶ 31. And it states that
    each such legal ―term[] of art‖ is presumed to carry ―the legal
    tradition and meaning‖ of its past practice, and ―the cluster of
    ideas that were attached to each borrowed word in the body of
    learning from which it was taken.‖ 
    Id.
     (emphasis added) (citation

    ―[W]hen a word or phrase is ‗transplanted from another legal

    change to a person‘s ―sex.‖ The concepts of ―name‖ and ―sex‖ are
    thus defined by the terms of the Utah Code. And the fact that the
    two terms both can be said to fall within the category of
    ―identifier‖ is not a reason to equate the two concepts.

    ¶274     This forecloses the majority‘s notion that the
    legislature ―planted . . . ‗sex change‘ in the name change‘s ‗old
    soil.‘‖ Supra ¶ 50. There is a common-law concept of and standard
    for a legal ―name change.‖ But there has never been a common-
    law concept of a ―sex change,‖ or a change in the legal designation
    of a person‘s ―sex.‖ This is purely a statutory term, with a ―legal
    tradition and meaning‖ and ―cluster of ideas‖ attached to it in the
    birth certificate context. And for that reason Maxfield actively
    undermines the majority‘s approach.
    ¶275     The majority thus identifies no support for its novel
    assertion that a statutory term takes on common-law meaning
    when ―combined‖ with common-law terms. And the court‘s
    analysis misses a nuance in the canon of interpretation that it
    relies on. A threshold principle, as noted, states ―[t]he age-old
    principle . . . that words undefined in a statute are to be
    interpreted and applied according to their common-law
    meanings.‖ SCALIA & GARNER, supra, at 320. But this canon has an
    important counterpart—the principle that a statute that employs a
    term with an established meaning in a statutory field is presumed
    to ―bear[] this same meaning‖ when adopted by the legislature. Id.
    at 324. This is an aspect of the ―prior construction canon‖—the
    principle that a term that has an established meaning in a
    ―particular field of law (to which the statute belongs)‖ is
    interpreted to carry that same meaning in a statute enacted by a
    legislature. Id.; see also Rutherford, 
    2019 UT 27
    , ¶ 62 (stating that a
    term whose meaning is ―firmly established‖ in a particular field is
    viewed as having been ―carried forward by the legislature‖).
    ¶276     This canon is sometimes invoked when a statute is
    reenacted in the face of a conclusive construction of a statutory
    term by a court of last resort. See SCALIA & GARNER, supra, at 324.
    But it is not limited to this application. ―It applies as well‖ to an
    established ―administrative interpretation‖ of a legal term in a
    given field. Id. Such an interpretation is part of the statute‘s
    context. See id. We understand that a legal term with accepted
    meaning in a given field ―bears this same meaning‖ when it is
    imported into a statute. Id.
    ¶277     Our Utah case law establishes this precise position.
    Where our legislature uses terms that have a settled
    ―administrative interpretation‖ in a particular field, that
    interpretation is understood to be carried forward in the statute.

    income from . . . property during the taxable year‖ as the
    legislative adoption of the ―administrative interpretation‖ of this
    language by the Tax Commission).116 The United States Supreme
    Court has likewise endorsed this view. See Fed. Deposit Ins. Corp. v.
    Phila. Gear Corp., 
    476 U.S. 426
    , 436–37 (1986) (endorsing the same
    canon in the context of Congress‘s adoption of a statute speaking
    of a ―deposit‖ in the estate tax context; holding that federal
    statutes adopting this language in this legal context are
    understood to carry forward the established understanding of the
    term).
    ¶278      The settled meaning of the ―sex‖ designation on a
    birth certificate has been established at the ground level—in the
    administration or practice of preparing and submitting birth
    certificates. At that level, all agree that the administrative concept
    of an original birth certificate ―sex‖ designation has long been
    viewed as a matter of biological sex.117
    ¶279    The administration of the statute may not require or
    call for an official interpretation by the Office of Vital Records.
    ―[R]ather, sex is designated (primarily) by medical professionals
    who presumably are not versed in the nuances of administrative
    definitions in the law.‖ Supra ¶ 53 n.23. But that just shows how
    deeply embedded the administrative practice is. The long-settled
    practice reflects the established administrative meaning of this
    term. And the lack of a need for agency interpretation just shows
    that the administrative practice is well-settled; it doesn‘t tell us
    that there is no understanding that should be carried forward
    under our law.
    ¶280     The majority‘s framework fails on this basis. As the
    court itself notes, the birth certificate amendment statute
    __________________________________________________________
    116 In New Park Mining Company v. State Tax Commission, the

    , 487
    (Utah 1948). I would also resolve this case based on the statute‘s
    plain meaning. See supra ¶¶ 207, 216. But the administrative
    construction canon would resolve this case even if the meaning of
    ―sex‖ bore any meaningful ambiguity.
    117 The agreement is not limited to members of this court.
    Statutes and case law confirm this understanding. See supra ¶¶ 85;

    articulates no express standard for an order for a ―change‖ to a
    birth certificate ―sex‖ designation—it just presupposes the
    authority for the issuance of such an order. That, again, is telling.
    The ―same meaning‖ is presumed to be carried forward in the
    legislature‘s presumption of court power to order a ―change‖ in
    that same designation.
    3.       Delegation to Courts in Other Jurisdictions
    ¶281     The majority also seeks to support its assertion of
    judicial policymaking power by noting that an amendment to a
    Utah birth certificate is required in response to an order for a
    change of a sex determination entered by ―a Utah district court or
    a court of competent jurisdiction of another state or a province of
    Canada.‖ Supra ¶ 78. A key premise of the majority‘s argument is
    the assertion that our legislature is somehow powerless to
    ―control the standard for ‗sex‘ or ‗sex change‘ applied by any
    other jurisdiction.‖ Supra ¶ 78. From that premise, the majority
    reasons that the legislature must have meant to ―omit a
    substantive standard from the statute,‖ supra ¶ 77 n.31, and thus
    to leave the development of the operative standard to the courts—
    whether in Utah or in other states or Canadian provinces.
    ¶282     The court‘s syllogism misses a key nuance that foils its
    central premise. It is undoubtedly the case that the Utah
    Legislature ―cannot control the standard for ‗sex‘ or ‗sex change‘‖
    for another jurisdiction’s birth certificates. Supra ¶ 78. But the Utah
    Legislature can and does control the legal standards defining the
    content of Utah birth certificates. And no other state (or province
    of Canada) is in a position to alter these Utah standards by
    entering an order under substantive standards developed in
    another jurisdiction.
    ¶283    The articulation of substantive state law is ―the very
    essence of . . . sovereignty.‖ Toler v. Oakwood Smokeless Coal Corp.,
    
    4 S.E.2d 364

    articulating the legal framework dictating the content of Utah

    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    ¶284    The Utah Legislature has exercised the state‘s
    sovereignty in statutes aimed at prescribing the content of the
    vital records issued by the State of Utah. See UTAH CODE § 26-2-1
    to 26-2-28 (providing framework for establishing the content of
    Utah vital records). A Utah birth certificate is thus a Utah vital
    record whose content is controlled by Utah law. And no other
    state has authority to alter the content of a Utah record by
    application of its contrary laws.
    ¶285     The Utah Legislature admittedly has directed our
    courts to defer to the judgments of other courts—to Canadian
    judgments as a matter of comity, and to judgments of the courts of
    other states as a constitutional matter of full faith and credit. See
    U.S. CONST. art. IV, § 1. But that isn‘t a delegation of power to
    courts in other jurisdictions to alter substantive Utah law. It is a
    simple recognition of the effect of those judgments.
    ¶286      Courts ―differentiate[] the credit owed to laws
    (legislative measures and common law) and to judgments.‖ Baker
    v. Gen. Motors Corp., 
    522 U.S. 222
    , 232 (1998). ―A final judgment in
    one State, if rendered by a court with adjudicatory authority over
    the subject matter and persons governed by the judgment,
    qualifies for recognition throughout the land.‖ 
    Id. at 223
    . But the
    principle of full faith and credit ―does not compel ‗a state to
    substitute the statutes of other states for its own statutes dealing
    with a subject matter concerning which it is competent to
    legislate.‘‖ 
    Id. at 232
     (quoting Pac. Emps. Ins. Co. v. Indus. Accident
    Comm’n, 
    306 U.S. 493
    , 501 (1939)). It requires only deference to a
    foreign state‘s judgment. And that state may be required to apply
    Utah ―statutes dealing with a subject matter concerning which‖
    our Utah Legislature is ―competent to legislate.‖ 
    Id.
    certificate is not a matter of substantive Utah law, then the courts
    of each state and Canadian province retain the power to apply
    their own law in this arena. To sustain that conclusion, we would
    have to assume that the Utah Legislature was delegating
    substantive authority to every other state and Canadian province
    to regulate and alter the framework for our Utah birth certificates.
    The majority‘s analytical framework is mistaken. A Utah birth
    certificate is a Utah vital record. Its terms and conditions are
    governed by Utah law. And neither the majority nor the Chief
    Justice has cited any support for their contrary views.

    ¶287    There is no question that the Utah Legislature is
    ―competent‖ to regulate the content of our Utah vital records.
    Utah law controls the content of Utah vital records. And courts in
    other jurisdictions are thus bound to apply Utah law in the
    issuance of any order directing the amendment of such records.119
    ¶288     Nothing in the statute at issue here suggests
    otherwise, or indicates that the legislature was conferring power
    on the courts of other states to impose their substantive law on the
    content of a birth certificate on the registrar of vital records in
    Utah. The statute provides only that Utah citizens and institutions
    may avail themselves of the courts of other states and may be
    controlled by such decisions. That leaves open the question of
    which state‘s substantive law should govern those decisions. And
    there can be no question that Utah law is the substantive law that
    governs the content of Utah vital records.120
    __________________________________________________________
    119 Courts in other jurisdictions apply our Utah law with some
    regularity—just as our courts do in reverse. See, e.g., Spann v. Am.

    , 51–52 (N.C. Ct. App. 2011) (applying Utah law to
    determine enforceability of a contract‘s forum selection clause).
    This is simply a matter of choice of law.
    120 The majority argues past my position in its response to the
    above. We can take as a given that the Utah registrar lacks
    ―discretion‖ in this field and is bound to give ―respect and
    reciprocity to court orders of sister jurisdictions.‖ Supra ¶ 78 n.33.
    We can also stipulate that the legislature could have stated more
    clearly its intent to have Utah law control the content of Utah
    birth certificates. Supra ¶ 78 n.33. But my threshold points remain
    unrefuted: (a) the statute speaks only to the full faith and credit to
    be given to judgments of courts of other jurisdictions; (b) the Utah
    registrar can give full faith and credit to such judgments without
    delegating to other courts the power to amend or revise our Utah
    substantive law; and (c) the content of a Utah birth certificate is a
    matter governed by Utah law.
    Courts in other jurisdictions would not be bound to follow our
    Utah law on justiciability. But see supra ¶ 78 n.33 (suggesting that I
    am arguing that courts in other states could not rule on non-

    ¶289    The majority‘s contrary view will give rise to an
    unworkable patchwork of standards for Utah birth certificates. It
    will require the Utah registrar to reformulate and revise the
    framework for a Utah birth certificate each time a court
    establishes a new conception of a person‘s sex under the
    substantive law of another state or province of Canada.
    ¶290      This is no mere hypothetical. Increasingly, courts in
    various states are developing standards for non-binary and other
    gender designations on birth certificates for persons born in those
    states.121 Under the majority‘s view, our Utah birth certificates will
    have to bow to and somehow incorporate these and other
    standards. The result will be the transformation of a Utah birth
    certificate into an evolving, patchwork certificate that will ebb and
    flow in response to orders entered under the law of other states
    and provinces of Canada.122 That is not what the Utah statute was
    adversarial petitions). But they would be bound to follow Utah
    law on the terms and conditions of a Utah vital record. That point
    stands unrefuted. And it undermines the inference drawn by the
    majority.
    121 See CAL. HEALTH & SAFETY CODE § 103430(a) (West 2021)
    (providing for an individual to petition for a court ―order for a
    new birth certificate‖ recognizing ―a change in the petitioner‘s

    mandating in requiring deference to decisions of the courts of
    other states.
    ¶291     If anything, the statutory structure cuts against the
    majority‘s approach. In placing Utah court decisions on par with
    the decisions of courts of other states and provinces of Canada,
    the legislature was indicating that the operative legal standard is
    not one to be developed by any of these courts. Instead, the
    standard is established by the settled understanding of a sex
    designation on a birth certificate—as a reference to a designation
    of biological sex based on physical observation.
    ¶292     The result is not a ―meaningless statute.‖ Supra ¶ 77
    n.31. It is a statute that presupposes the existence of a settled
    understanding of the basis for a sex designation, and sees no need
    to articulate it in the express terms of the statute.
    4.    Constitutional Avoidance
    ¶293     The majority‘s inferences from the purported
    statutory ―gap‖ also raise serious constitutional questions. To the
    extent the court is asserting that there is literally ―no statute,‖
    supra ¶ 45, that says anything of relevance to the operative concept
    of an order for a change in a ―sex‖ designation on a birth
    certificate, its analysis raises serious constitutional questions
    under the non-delegation doctrine. And that is a further basis for
    questioning the majority‘s approach.
    ¶294     Our constitution gives ―[l]egislative power‖ to the
    Utah Legislature. UTAH CONST. art. VI, § 1. This is the authority to
    make legislative policy by ―bill or joint resolution . . . passed . . .
    with the assent of the majority of all the members elected to each
    house of the Legislature.‖ Id. art. VI, § 22. Subject to further terms
    and conditions set forth in article VI, the legislature has the power
    to ―promulgat[e] . . . laws of general applicability . . . based on the
    weighing of broad, competing policy considerations.‖ Carter v.
    Lehi City,

    , 381 (Utah 1970) (speaking of the legislative power as
    ―the authority to make laws‖).
    ¶295    The constitutional doctrine of separation of powers
    precludes the delegation or assignment of these powers. Under
    human rights laws, however, do not control substantive Utah law,
    and do not dictate the content of Utah birth certificates.

    article V, section 1, our government is ―divided into three distinct
    departments, the Legislative, the Executive, and the Judicial.‖
    UTAH CONST. art. V, § 1. And ―no person charged with the exercise
    of powers properly belonging to one of these departments, shall
    exercise any functions appertaining to either of the others, except

    Utah Constitution. State v. Johnson, 
    137 P. 632
    , 634 (Utah 1913). So
    if there were truly an ―absence of legislative enactment‖ on the

    anticipated by the legislature, ―it would savor of

    be established by the legislature. Clayton v. Bennett, 
    298 P.2d 531
    ,
    535 (Utah 1956) (citation omitted). But once the core policy is

    at 4 (citation omitted). At a minimum, the legislature must ―mark
    the course to be pursued, and the principles, facts, and purposes
    to serve as guideposts to enable‖ another branch of government
    ―to carry out‖ not its ―own will or judgment but that of the
    legislature.‖ Id. Other governmental departments may thus ―only
    effect policy mandated by statute and cannot exercise a sweeping
    power to create whatever rules they deem necessary.‖ Robinson,
    
    2001 UT 21
    , ¶ 14.
    ¶299     These standards have been illuminated by their
    application in a range of cases. This court has held, for example,
    that the legislature may not delegate to the courts or to other
    departments the unguided discretion to adopt a ―definition of a
    crime‖ or prescribe ―the precise punishment therefor,‖ Briggs,
    
    2008 UT 83
    , ¶ 14 (citation omitted); Johnson, 137 P. at 634
    (describing such act as unconstitutional ―judicial legislation‖); to
    make a wholly discretionary judgment as to ―the amount of [a]
    penalty‖ as a ―sanction‖ for non-payment of a tax, Tite v. State Tax
    Comm’n, 
    57 P.2d 734
    , 740 (Utah 1936); or to make a policy
    determination as to ―the standards or purposes which are to
    control‖ the fixing of prices for ―surplus milk,‖ Rowell, 99 P.2d at
    4.
    ¶300      The analysis and holdings of these cases are
    illustrative. Because there is no common law of crimes in Utah,
    there is no independent power for our courts to make our own
    policy judgments on the basis for filling in perceived gaps in
    criminal enactments. To do so would ―savor of judicial
    legislation‖—in unconstitutionally supplementing the criminal
    code with our own policy preferences. Johnson, 137 P. at 635
    (citation omitted). That principle holds even where our judicial
    moral compass may ―regret[]‖ that there is a gap in a statute. Id.
    (noting that it is up to the legislature to decide whether to fill in
    such a gap).
    ¶301      Parallel concerns informed our decision to foreclose
    the legislative power to delegate to other departments the amount
    of a sanction for non-payment of a tax. In repudiating the
    constitutionality of the delegation of that power to the tax
    commission, we highlighted the legislature‘s failure to give the
    commission any ―basis‖ for ―ascertain[ing] the amount of the
    penalty.‖ Tite, 57 P.2d at 740. Absent such basis, we found a
    125
    IN RE SEX CHANGE
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    constitutional defect in any decision to give ―to the tax
    commission the power to determine in its own judgment the
    amount of the penalty.‖ Id. (emphasis added). And we viewed
    that as a ―legislative function which could not be delegated.‖ Id.
    ¶302     This was also the basis for our decision to strike down
    a purported delegation of the power to set state policy on price
    fixing of surplus milk. In our Rowell opinion, we condemned the
    alleged delegation of ―unfettered choice‖ to the board of
    agriculture to establish legislative policy. See Rowell, 99 P.2d at 3
    (quoting Elite Dairy Prod’s. v. Ten Eyck, 
    3 N.E.2d 606
    , 609 (N.Y.
    1936)). And we emphasized that the legislature must ―mark the
    course to be pursued‖ with a set of legislative ―guideposts,‖ and
    could not delegate to another department the authority to carry
    out its ―own will or judgment.‖ Id. at 4. Where the ―only
    prerequisite‖ to the adoption of a new policy is the ―arbitrary
    assent‖ of a non-legislative body, there is a ―naked delegation of
    legislative power,‖ and a violation of the Utah Constitution. Id. at
    5 (citation omitted).
    ¶303     The majority‘s decision runs afoul of these principles
    to the extent it relies on its own purported power to make policy
    as a matter of the common law. In asserting the authority to
    engage in its own act of policymaking, the court contends that
    ―neither Utah Code section 26-2-11 nor any other statute contains
    explicit standards or procedures for petitions for sex change.‖
    Supra ¶ 47 (emphasis added). In light of the legislature‘s
    purported failure to legislate, the court asserts the broad
    prerogative of judicial policymaking as a matter of our ―common-
    law authority,‖ which in its view ―is not dependent on or limited
    by a statutory provision‖ that does not expressly foreclose such
    power. Supra ¶ 50 n.22. These conclusions are mistaken not only
    because any supposed gap can be filled through statutory
    interpretation, but also because there is no such thing as a
    ―common law‖ of amendments to a sex designation on a birth
    certificate. This is fatal under the above-cited case law. Even
    assuming for the sake of argument that the legislature has left a
    completely empty space that cannot be filled as a matter of
    statutory interpretation, we could not on that basis assert the right
    to engage in common-law policymaking.
    ¶304      The law on amendments to a sex designation on a
    birth certificate is like the criminal law. This is not a common law
    field—there is no common law that governs. And the purported
    lack of any statutory standard cannot be taken as a ―naked
    126
    Cite as: 
    2021 UT 13
    ASSOCIATE CHIEF JUSTICE LEE, dissenting
    delegation‖ of policymaking power. Rowell, 99 P.2d at 4. The
    court‘s insistence on the existence of such power is the assertion of
    the authority to make ―judicial legislation,‖ Johnson, 137 P. at 634,
    which would run afoul of the Utah Constitution.
    ¶305     Again it is no answer to suggest that the court is just
    ―apply[ing] the common law associated with name-change
    petitions.‖ Supra ¶ 54. The court has borrowed a single element
    from the law of name changes—in the prohibition of petitions
    sought for a ―wrongful or fraudulent purpose.‖ Supra ¶ 18. But
    the core standard established by the court goes well beyond that
    threshold requirement. The new standard for a ―gender identity‖
    entry on a birth certificate is a matter of the majority‘s own
    making. That standard bears no relation to any element of a
    common-law name-change proceeding. It likewise bears no
    connection to the text of the governing statute. And for these
    reasons it amounts to an act of judicial legislation unbound by the
    terms or conditions of any common-law or any statute.
    ¶306     The court‘s reformulation of the legislature‘s concept
    of the sex designation on a birth certificate raises serious
    constitutional concerns. To the extent the majority is suggesting
    that there is no legislative standard that governs—and bare
    policymaking power delegated to the courts—its approach should
    be rejected as a matter of constitutional avoidance.
    III. CONCLUSION
    ¶307      Since 1975 our Utah law has provided for the issuance
    of a court order for amendment of the designation of a person‘s
    ―sex‖ on a birth certificate. This is a plain reference to biological
    sex. It is not an invitation for judicial development of an evolved
    standard of ―gender identity.‖
    ¶308     The majority‘s new standard provides for a birth
    certificate amendment upon a showing of any care or treatment
    for gender transitioning or change. This was not the law enacted
    by our legislature in 1975. And it is not the law this court should
    be adopting—least of all in a case in which we lack adversary
    input from any adversary party.
    ¶309     The legislature can certainly ―override‖ our decision if
    it disagrees. See supra ¶ 54. But that is no reason for us to step in to
    do the legislature‘s job of amending or updating its laws. And it
    surely is no justification for our court‘s decision to override
    decades and even centuries of precedent on the core limits on our
    judicial power.

    ¶310      The legislature has no power to undo that decision. In
    a system that gives our court the final say on constitutional
    questions, we ourselves bear the responsibility to interpret and
    abide by the limits on our constitutional power. We should hold
    those limits sacred. We will rue the day that we cast them aside.
