    2The Honorable Rod W. Smeltzer, Dunn County Circuit Court,
    presided.
    No.        2018AP2104
    from his commitment as a sexually violent person.                             Stephenson
    raises     three    issues.      First,          he   contends   that     Chapter         980
    requires the State to present expert testimony in order to prove
    he is dangerous because his mental disorder makes it more likely
    than not that he will re-offend in a sexually violent manner.
    Because the State failed to do so, Stephenson asserts there is
    insufficient evidence to continue his Chapter 980 commitment.
    Second, Stephenson asks this court to overrule the sufficiency-
    of-the-evidence standard of review this court adopted in Curiel.3
    Third, he claims that even if expert testimony is not required,
    and   even    if    we    do   not    overrule         Curiel,   the    evidence          was
    nevertheless        insufficient       to        support   the     circuit          court's
    decision denying his petition for discharge.
    ¶2      We hold the State is not required to present expert
    testimony to prove the required dangerousness element in Wis.
    Stat. § 980.01(7) (2017-18).4                    We further reject Stephenson's
    request      to    overrule    Curiel       and,      instead,   reaffirm          Curiel's
    holding     that    the   appropriate        standard      of    review       to    use   in
    Chapter 980 cases is the sufficiency-of-the—evidence test set
    forth in our criminal law.               Finally, we hold the evidence of
    record satisfies the sufficiency-of-the-evidence standard.                                 We
    affirm the decision of the court of appeals.

    No.    2018AP2104
    ¶3     Stephenson has a lengthy history of committing sexual
    assaults.      In 2000, when he was 15 years old, the State charged
    Stephenson with three counts of fourth-degree sexual assault.
    One of these charges resulted in a delinquency adjudication.                In
    2001, Stephenson sexually assaulted a high school classmate.                In
    that case, Stephenson led the student to a secluded area of the
    high school, forcefully pushed her up against a wall, pulled
    down   her    pants,   and   began   engaging   in   forced    intercourse.
    Stephenson was subsequently adjudicated delinquent for second-
    degree sexual assault of a child.
    ¶4     In 2004, Stephenson engaged in sexual intercourse with
    two 15-year-old girls.          The State charged Stephenson with two
    counts of second-degree sexual assault of a child, and he later
    pled guilty to two counts of fourth-degree sexual assault of a
    child.      The circuit court placed him on two years of probation.
    Also in 2004, Stephenson engaged in sexual intercourse with a
    12-year-old girl in Minnesota when he was 19 years old.                    The
    State of Minnesota charged Stephenson with one count of second-
    degree      criminal   sexual   conduct.    Stephenson    was       ultimately
    convicted of this charge and placed on 25 years of probation.
    ¶5     In 2007, Stephenson corresponded with a 14-year-old
    girl over the internet and lied to her about his age.                 When he
    eventually met her face-to-face, Stephenson pinned her down and
    forced her to engage in sexual intercourse.              That same year,
    Stephenson restrained a 16-year-old girl and forcibly engaged in
    sexual intercourse with her while her parents were away.                   The
    girl was eventually able to escape.

    No.           2018AP2104
    ¶6      For   these     incidents       in    2007,      the       State           charged
    Stephenson     with   two     counts   of      sexual        assault          of    a     child.
    Stephenson     subsequently     pled   guilty           to   one    count          of    second-
    degree sexual assault of a child and, in 2009, was sentenced to
    two   years    of   initial    confinement         followed        by    four       years      of
    extended supervision.           In 2011, as Stephenson's release date
    neared, the State filed a petition to qualify Stephenson as a
    "sexually violent person," pursuant to Wis. Stat. ch. 980.                                    The
    circuit court committed Stephenson to a secure mental health
    facility.
    ¶7      In 2017, Stephenson petitioned the circuit court to
    discharge him from commitment.                The State opposed Stephenson's
    release.        The   circuit     court       considered           his    petition            and
    conducted a discharge trial.           In order to continue Stephenson's
    commitment on the basis that he remained a "sexually violent
    person," the State was required to prove three elements by clear
    and convincing evidence:          (1) that he has been convicted of a
    sexually violent offense [hereinafter the "first element"],5 (2)
    that he has a mental disorder that predisposes him to acts of
    sexual violence [hereinafter the "second element"],6 and (3) that
    he is dangerous to others because the mental disorder makes it
    more likely than not that he will engage in one or more future
    5"Sexually      violent     offense"         is    defined         in    Wis.        Stat.
    § 980.01(6).
    6In full, "mental disorder" is defined as a "congenital or
    acquired condition affecting the emotional or volitional
    capacity that predisposes a person to engage in acts of sexual
    violence." Wis. Stat. § 980.01(2).
    4
    No.       2018AP2104
    acts of sexual violence [hereinafter the "third element"].                                 Wis.
    Stat. § 980.01(7).
    ¶8     At the discharge trial, there was no dispute over the
    first   element:           Stephenson        had     been    convicted    of     a   host     of
    sexually violent offenses.                   In order to establish the second
    element, the State introduced testimony from an expert witness,
    Donn    Kolbeck,      a    psychologist         employed       by   the    Department         of
    Health Services (DHS) who had previously evaluated Stephenson.
    Kolbeck      testified          that    he     diagnosed        Stephenson       with       two
    qualifying mental disorders:                    (1) Other Specified Personality
    Disorder,      with       antisocial      and       borderline      features,        and    (2)
    Alcohol Abuse Disorder.
    ¶9     Kolbeck          testified        that        Stephenson's       personality
    disorder meant that he possesses an "enduring pattern of inner
    experience and behavior that deviates . . . markedly from the
    expectations          of       the      individual's           culture      leading           to
    impairments[]             in      cognitions,               emotions,      interpersonal
    functioning, and impulse control."                     Kolbeck further stated that
    Stephenson exhibits "a long history of deceitfulness, conning
    and manipulation in the context of sexually violent behaviors,
    impulsivity,     irritability,           consistent          irresponsibility,          and    a
    lack    of     remorse."               According        to     Kolbeck,        Stephenson's
    personality disorder "has a direct causal connection to [his]
    sexually violent behaviors in the community."
    ¶10    With regard to the other qualifying mental disorder,
    Kolbeck      testified         that,   while        Stephenson's     symptoms        were     in
    remission given his controlled environment, Stephenson's "use of
    5
    No.     2018AP2104
    alcohol . . . was a condition that predisposed him to engage in
    acts    of    sexual           violence."             He     further        testified            that
    Stephenson's       alcohol           consumption           grew    heavily        over        time,
    progressing        to     "frequent           intoxication"          during           his     life.
    According     to     Kolbeck,         Stephenson       also       admitted      that        he   had
    "never committed a crime sober" and that he was still "capable
    of social drinking" in the community.
    ¶11   Additionally, Kolbeck testified regarding Stephenson's
    numerous      rule       violations           while        committed.           Noting           that
    Stephenson's       anti-social           traits       were    "still      active,"          Kolbeck
    explained     that      Stephenson          repeatedly       covered      his    room        window
    with a towel, despite contrary instructions from staff.                                          When
    confronted with this violation, Stephenson lied, claiming this
    behavior     had        been        allowed    by      other       unit     staff       members.
    Additionally, while in confinement, Stephenson had been cited
    repeatedly for trying to obtain property that he was not allowed
    to have.     In one case, Stephenson violated the rules by ordering
    women's      lingerie——an            item     expressly           prohibited          under       the
    facility's policies.
    ¶12   Kolbeck       also          stated       that     Stephenson         produced          a
    concerning     result          on    a   non-suppressed            penile    plethysmograph
    test,     during        which        Stephenson        became       aroused       by        stimuli
    "depicting teenager coercive interactions" as well as by graphic
    depictions of "victims crying or in some form of suffering"
    related to sexual deviancy.                    Kolbeck testified that Stephenson
    tested highly on measures of psychopathy, as quantified by the
    Psychopathy Checklist—Revised (PCL-R).                            While most individuals
    6
    No.    2018AP2104
    in the "prison population" score "roughly 23" on the PCL-R,
    Stephenson    scored     a    "29,"   which      is   "consistent    with     a   high
    degree of psychopathy."             Kolbeck opined that these indicators
    suggest    that   Stephenson      manifests       characteristics      of    shallow
    affect, grandiosity, and manipulation.
    ¶13     Next, Kolbeck addressed the third element:                       whether
    Stephenson's mental disorder makes it more likely than not that
    he will engage in one or more future acts of sexual violence.
    In opining on this issue, Kolbeck employed two actuarial risk
    instruments       to      measure        Stephenson's         risk     of     future
    dangerousness:         the Static-99R and the Violence Risk Scale—Sex
    Offense    Version     (VRS-SO).         Based   on   these    assessment      tools,
    Kolbeck concluded that Stephenson had a 41 percent probability
    of re-offending.         Importantly, Kolbeck defined "re-offense" as
    the probability of Stephenson being arrested or charged with a
    sexual crime, not his actual likelihood of committing future
    acts of sexual violence.            Stephenson's score on this instrument
    (41 percent) was lower than the "more likely than not" standard
    required for the third element.                As a result, Kolbeck concluded
    that, under this measure, Stephenson did not satisfy the third
    element.
    ¶14     Following        Kolbeck's    testimony,     Stephenson        introduced
    his own expert witness, Courtney Endres, a psychologist whose
    evaluation of Stephenson supported his discharge petition.                        With
    respect to the second element, Endres testified that Stephenson
    "no longer meets the criteria for a mental disorder as defined
    under Wisconsin Chapter 980."              As to the third element, Endres
    7
    No.    2018AP2104
    opined that Stephenson's "risk falls below the threshold" and
    that he "is not likely to reoffend in the future."                              Although
    Endres used the same Static-99R and VRS-SO instruments employed
    by Kolbeck, Endres applied slightly different risk assessment
    factors and determined that Stephenson posed a 10 percent risk
    of re-offense over five years and a 17 percent risk over ten
    years.       Accordingly, Endres concluded that Stephenson no longer
    met the statutory criteria for commitment as a sexually violent
    person.
    ¶15    Stephenson       also        presented    testimony       from      Darren
    Matusen,      a    psychologist       at    Stephenson's       treatment       facility.
    Matusen explained Stephenson's intensive three-phase treatment
    program      during    commitment      and    stated    that    Stephenson       was    in
    phase three of this program.                He opined that Stephenson had made
    progress in his treatment, even though he "is still callous at
    times."      He also stated that, while Stephenson "has a history of
    minimizing the seriousness of his sexual offenses," he has more
    recently      "acknowledged       that        adolescents       are   incapable         of
    consent" and has "taken responsibility" for his crimes.                          Matusen
    also     testified     that,    during        the    previous    year,        Stephenson
    assessed his own risk of re-offending as a "five out of ten"
    chance.
    ¶16    After hearing all of the testimony, the circuit court
    denied Stephenson's discharge petition, finding that he remained
    a sexually violent person.                  The court ruled that, based upon
    Kolbeck's         testimony,   Stephenson           suffers    from   both      of     the
    aforementioned        mental    disorders        and    "does    have     a    risk    to
    8
    No.        2018AP2104
    reoffend."      Nonetheless,         the     circuit       court   acknowledged           that
    Stephenson "has made significant progress" in his treatment and
    therefore granted him supervised release pursuant to Wis. Stat.
    § 980.08(4)(cg).
    ¶17     Following         the       circuit        court's          determination,
    Stephenson filed a motion for postcommitment relief.                                 In his
    motion,    Stephenson        conceded      the     first     two    elements         of   the
    criteria     for     commitment       as     a     "sexually        violent        person,"
    challenging only the third element.                  Stephenson argued the State
    failed to meet its burden of proof on the third element because
    no expert testified that he was more likely than not to commit a
    future act of sexual violence.                   Specifically, Kolbeck testified
    that Stephenson's risk of arrest or conviction for committing
    future acts of sexual violence was only 41 percent, a figure
    failing    to      satisfy    the     "more       likely     than      not"        standard,
    Stephenson argued.           Stephenson further claimed that, even if
    expert testimony was not required for the third element, the
    State's evidence was insufficient to prove that Stephenson was
    dangerous.      The circuit court denied this motion, holding that
    the State was not required to present expert testimony on the
    third element and that the State presented sufficient evidence
    to deny his discharge.              Stephenson appealed, and the court of
    appeals    affirmed     the        circuit       court's     ruling.          We    granted
    Stephenson's petition for review.
    II.    STANDARD OF REVIEW
    ¶18     Stephenson asks this court to interpret Wisconsin's
    sexually violent person commitment laws under Wis. Stat. ch. 980
    9

    III.    DISCUSSION
    A. Expert Testimony for Chapter 980 Proceedings
    ¶19    Stephenson contends that, during Chapter 980 discharge
    trials, the State must present expert testimony to satisfy its
    burden of establishing the third element:                   that the committee is
    dangerous to others because his mental disorder makes it more
    likely than not that he will engage in one or more future acts
    of sexual violence.       Wis. Stat. § 980.01(7).              Stephenson asserts
    that,   because    the   State's        expert      witness    failed      to    testify
    Stephenson was "more likely than not to reoffend," the circuit
    court wrongfully denied his petition for discharge.                         We are not
    persuaded.
    10
    No.     2018AP2104
    ¶20    In     essence,    Stephenson         asks        this     court    to     breathe
    requirements into a Wisconsin statute that are textually absent.
    Nowhere does Wis. Stat. ch. 980 require expert testimony for
    determinations of a committee's dangerousness, nor should this
    court invade the province of the legislature to create a rule
    out   of     whole    cloth.       Indeed,        the    legislature        is        capable   of
    enacting       such     language      if      it        chooses.           In     Wis.     Stat.
    § 980.07(1), for example, the legislature requires that expert
    examiners         conduct   "reexamination[s]                of    the     person's       mental
    condition         . . . [every]      12     months         to     determine whether             the
    person has made sufficient progress for the court to consider
    whether the person should be . . . discharged."                             Similarly, the
    legislature expressly invites courts to hear expert testimony
    when a committee denies the facts in a petition alleging that he
    is    sexually       violent.        Wis.    Stat.       §      980.031.7         Not    so     for
    § 980.09.           While   this      court        could        mandate     expert       witness
    testimony to support the third element, we decline to do so.
    "The requirement of expert testimony is an extraordinary one,
    and   [it     is   applied]     by    the    trial       court      only    when       unusually
    complex      or    esoteric     issues      are    before         the    jury."         White   v.

    149 Wis. 2d 949

    "If a person who is the subject of a petition filed under
    7
    § 980.02 denies the facts alleged in the petition, the court may
    appoint at least one qualified licensed physician, licensed
    psychologist, or other mental health professional to conduct an
    examination of the person's mental condition and testify at
    trial." Wis. Stat. § 980.031.
    The dissent cites the "Basic Guide to Wisconsin Small

    ¶21    As     a     general        matter,        expert       testimony         may       be
    admissible at trials if, inter alia, "scientific, technical, or
    other specialized knowledge will assist the trier of fact to
    understand the evidence or to determine a fact in issue."                                    Wis.
    Stat.   § 907.02(1).9          But     within      the    context       of   Chapter         980,
    the need for" expert testimony from a "full-time mechanic or a
    repair person" in a "motor vehicle faulty repair case."
    Dissent, ¶¶58-59.    Neither the guide nor Wisconsin law says
    that.   Setting aside the fact that "[t]his document is only a
    general guide" and not the law, the language cited by the
    dissent simply says that if a party is planning to present the
    testimony of an expert witness, it is "almost always necessary"
    to have the expert testify in person:
    Having the expert witness testify in person is almost
    always necessary. Merely repeating what your expert
    told you will probably not be allowed. A written
    statement or affidavit from the expert witness will
    not be sufficient.
    While "My Cousin Vinny" certainly established how compelling
    expert testimony can be regarding the characteristics of a car,
    the dissent's claim that "this court acknowledges the need for
    an expert to testify even in a small claims motor vehicle faulty
    repair case" is plainly wrong.
    9 Contrary to the dissent's construction of Wis. Stat.
    § 907.02(1), nothing in the text of this statute requires the
    admission of expert testimony; to the contrary, its language is
    permissive rather than mandatory, affording the trial court the
    discretion to admit expert testimony if it will "assist the
    trier of fact":
    If scientific, technical, or other specialized knowledge will assist the trier of fact
    to understand the evidence or to determine a fact in issue, a witness qualified as
    an expert by knowledge, skill, experience, training, or education, may testify
    12
    No.     2018AP2104
    determinations of future dangerousness rest soundly within the
    purview of lay factfinders.                 Courts recognize factfinders to be
    quite   adept      at     understanding           how    an    individual's          criminal
    history, admissions of wrongdoing (or lack thereof), performance
    on supervision, or progress in treatment inform his likelihood
    of committing future acts of violence.                          See, e.g., State v.
    Randall,    2011    WI    App     102,      ¶¶9-10,      19,

       (holding       that,      in    a    case    involving      a    petitioner's
    commitment    on    grounds       of     insanity,        the     factfinder         properly
    concluded that the petitioner's past crimes and poor behavior
    during commitment showed that he "still pose[d] a danger to
    society");       Estelle     v.     Smith,         
    451 U.S. 454
    ,     472     (1981)
    (discussing the important role of a factfinder in assessing an
    individual's future danger to society).
    ¶22     In     this     case,      Kolbeck          testified      that,       based    on
    calculations using Static-99R and VRS-SO, Stephenson had a 41
    percent risk of re-offending, which he defined as the risk of
    being arrested and charged with a crime of sexual violence.
    While this is below the threshold of "more likely than not," a
    factfinder       could    reasonably         determine         that    other        evidence,
    separate from these actuarial instruments, weighs in favor of
    continued    commitment         based       on    the    likelihood      of        Stephenson
    thereto in the form of an opinion or otherwise, if the
    testimony is based upon sufficient facts or data, the
    testimony is the product of reliable principles and
    methods, and the witness has applied the principles
    and methods reliably to the facts of the case.

    committing future acts of sexual violence, regardless of whether
    he ultimately faced arrest or charges as a result.      For example,
    Kolbeck testified that Stephenson scored disproportionately high
    on measures of psychopathy, repeatedly violated the treatment
    facility's policies, and generated a concerning result on his
    non-suppressed   penile   plethysmograph    test.    Weighing    these
    additional factors falls squarely within the comprehension and
    competency of lay factfinders.     After all, in a variety of other
    sorts of cases, a factfinder's principal duty involves reviewing
    the entire panorama of evidence, weighing its significance, and
    drawing conclusions therefrom.10      See, e.g., Jackson v. Virginia,
    
    443 U.S. 307
    , 318-19 (1979) (discussing how factfinders must
    weigh the evidence and draw reasonable inferences in criminal
    trials); Lang v. Lowe,

    (discussing how factfinders appropriately weigh
    evidence in civil actions).
    ¶23   No Wisconsin appellate court has ever required trial
    courts to hear expert testimony on the third element.        More than
    two decades ago, this court expressly declined to create such a
    rule and held that the circuit court properly considered the
    State's other evidence——namely, that the committee had a 25-year
    10Of course, this is not to say that a factfinder would not
    benefit from hearing expert testimony on the third element. As
    the State admits, it may often prove difficult for the State to
    demonstrate without an expert a committee's likelihood of
    engaging in future acts of sexual violence sufficient to render
    him dangerous to others. But to mandate expert testimony is an
    entirely different matter.

    the issue of future acts of sexual violence in this case," it
    need not opine on whether "expert testimony is required as a
    matter of law.").       Likewise, the United States Supreme Court has
    never   required    experts      to    testify    on     "future   dangerousness"
    either.      In Estelle v. Smith, 
    451 U.S. 454
    , 472 (1981), the
    Court held that, on the issue of capital sentencing procedures
    (which require a determination of "dangerousness"), "the jury's
    resolution of the future dangerousness issue is in no sense
    confined to the province of psychiatric experts."                         In another
    case, the Court stated that experts should not have the only say
    in whether or not an individual is dangerous, given that lay
    juries and courts can "sensibly" arrive at such conclusions.

    ¶24   Stephenson relies heavily upon Wal-Mart Stores, Inc.
    v. LIRC, 
    2000 WI App 272

    240 Wis. 2d 209

    respondent is dangerous."             Both cases are inapposite.             In Wal-
    Mart Stores, an employee brought an employment discrimination
    suit    alleging   that    his    employer       fired    him     because    of    his
    obsessive-compulsive disorder (OCD).

    , ¶¶2-3.
    15
    No.     2018AP2104
    The court of appeals held that the employee needed to present
    expert    testimony       in    order      to    prove    that    his    OCD     caused    the
    behavior     that       led    to    his     firing.
    Id., ¶16.
            While     the
    employee's     therapist            testified        regarding    the    employee's        OCD
    diagnosis, she provided no evidence that the OCD caused the
    behaviors triggering his firing.
    Id., ¶23.
        In the absence of
    such expert testimony, the court of appeals concluded the Labor
    and Industry Review Commission erred in determining that Wal-
    Mart discriminated against the employee on the basis of his
    disability.
    Id., ¶1.
             Similarly, the court of appeals in B.P.
    decided     that    a    parent      facing      termination       of    parental      rights
    needed to present expert testimony to support his assertion that
    his   psychological            condition        caused     him     not     to     visit     or
    communicate with his child.                
    386 Wis. 2d 557
    , ¶48.               Without such
    expert testimony, the court concluded that the trier of fact
    would have to speculate.
    Id., ¶49.
           Unlike either of those
    cases, in this Chapter 980 proceeding, an expert witness did
    supply the causal link between Stephenson's mental disorder and
    his prior sexually violent behaviors.                       Kolbeck testified that
    Stephenson's        personality            disorder       "has     a      direct       causal
    connection     to        [his]        sexually        violent      behaviors          in   the
    community."
    ¶25    Notwithstanding            this     linkage    established          by    expert
    testimony, Stephenson nevertheless argues that the holdings of
    Wal-Mart     Stores      and     B.P.      should      prohibit    a     factfinder        from
    determining that a committee is dangerous to others without an
    expert    witness       opining       that      the    committee's       mental    disorder
    16
    No.    2018AP2104
    makes it more likely than not that he will engage in one or more
    future acts of sexual violence.                        We disagree.          The rule applied
    in   Wal-Mart      Stores       and       B.P.    does       not    fit    the     factfinder's
    determination under Wis. Stat. § 980.01(7).                                Unlike the third
    element      of    that      statute,            the     inquiries         requiring       expert
    testimony         in      Wal-Mart         Stores        and        B.P.        were      entirely
    retrospective, involving whether mental health conditions caused
    behaviors that had already occurred.                               The    issue in        Wal-Mart
    Stores was whether the employee's past conduct was caused by his
    mental disorder; similarly, the issue in B.P. was whether the
    parent's past conduct was caused by his psychological condition—
    —both decidedly different inquiries than in Chapter 980 cases,
    in   which     any      proffered         expert        testimony         would       inform    the
    committee's propensity to commit future acts of sexual violence.
    In other words, the court of appeals deemed expert testimony
    necessary     to       establish      a    causal       link       between      the     employee's
    disorder and the conduct for which he was fired in Wal-Mart
    Stores,   as      well     as   to    establish          a     causal      link    between      the
    father's psychological condition and the conduct for which the
    State sought to terminate his parental rights in B.P.                                     Both of
    these   considerations           fall       beyond       the       competence      of     the   lay
    factfinder,        who,    without         expert       testimony,         cannot        determine
    whether a mental health condition or a disorder did in fact
    cause   particular         behaviors.             In    contrast,         the    third    element
    under Wis. Stat. § 980.01(7) asks the factfinder to make a risk
    assessment regarding the likelihood the committee will engage in
    17
    No.    2018AP2104
    future acts of sexual violence, a predictive determination long
    regarded as well within the province of the lay factfinder.
    ¶26   Significantly, Chapter 980 cases involve a multitude
    of supplemental evidence pertinent to the third element that is
    simply irrelevant in employment discrimination and termination
    of parental rights cases.              In discharge proceedings, the State
    typically    presents     evidence       of     the     committee's     progress      in
    treatment, his performance on psychometric evaluations, and the
    nature of his mental disorder.                 The factfinder in Chapter 980
    cases has a comprehensive range of evidence at its disposal when
    assessing whether an individual's mental disorder makes it more
    likely than not that he will re-offend in a sexually violent
    manner——a        characteristic        often    lacking        in    ordinary      civil
    disputes involving psychological evaluations.                       In this respect,
    among    others,     Chapter     980    cases     are    an    entirely       different
    species of law compared to ordinary civil disputes.                          After all,
    "[t]he    primary     goals    and     purposes    of    ch.    980   are     to   treat
    sexually violent persons and to protect society from the danger
    posed by those persons," and the array of evidence available to
    factfinders reflects these consequential aims.                      In re Commitment

    Wis.     Stat.     § 980.01(7)       suggests     that     expert      testimony     is
    required to prove that an individual is dangerous to others
    because his mental disorder makes it more likely than not that
    he will commit future acts of sexual violence.                          Stephenson's
    argument rests upon his interpretation of language in State v.

    indicating that § 980.05(4) "contemplates that the state must
    put   forth       expert      evidence     showing        the   respondent's      mental
    disorder."         According        to   Stephenson's       argument,      because    the
    statute directly links the mental disorder to the individual's
    likelihood to re-offend in a sexually violent manner, if expert
    testimony     is     required       to   prove     the     existence    of    a    mental
    disorder, expert testimony must also be required for the third
    element.     We are unpersuaded.
    ¶28    As     a     preliminary      matter,         whether     Wis.   Stat.     §
    980.05(4) requires expert testimony to establish a committee's
    mental disorder was not an issue before the court in Sorenson.
    It is not necessary for us to resolve that issue in this case
    either.       As    Stephenson       concedes,      Kolbeck's        diagnoses    supply
    sufficient evidence to establish that Stephenson has a mental
    disorder that predisposes him to acts of sexual violence.                             The
    State's     expert       linked     Stephenson's     mental       disorder    with    his
    potential for recidivism (thereby satisfying the second element)
    and   it    was    the    factfinder's      role     to    then   determine       whether
    19
    No.   2018AP2104
    Stephenson's mental disorder made him more likely than not to
    commit a future act of sexual violence (the third element).11
    ¶29   As Chapter 980 makes clear, a "mental disorder" is a
    "congenital      or   acquired    condition      affecting        the    emotional    or
    volitional capacity that predisposes a person to engage in acts
    of sexual violence."         Wis. Stat. § 980.01(2) (emphasis added).
    Accordingly, when an expert testifies to a committee's mental
    disorder, he establishes that the committee has a predisposition
    for acts of sexual violence.               The next statutory step involves
    assessing the likelihood the committee will commit such acts in
    the    future.        Logically,         when    ascertaining       a     committee's
    potential for committing acts of sexual violence in the future,
    the    factfinder      necessarily        ties     its    determination         to   the
    predisposition produced by the mental disorder.                     In other words,
    when    providing     testimony     sufficient       to   establish       the    second
    element,     the   expert   lays    the     foundation      for    any    forthcoming
    evidence     pertinent      to     the     third     element.            Because     the
    determination of whether the committee is more likely than not
    to engage in future acts of sexual violence remains squarely
    The dissent misconstrues the court's statutory analysis
    11
    by suggesting that the "majority's interpretation of Wis. Stat.
    § 980.01(7)   erroneously   collapses   the   required   statutory
    elements from three to two."    Dissent, ¶61.   Of course, simply
    because expert testimony is not required for the third element
    does not mean that the element falls away.            The dissent
    misunderstands the simple issue in this case, which is whether
    expert testimony is necessary to determine whether it is more
    likely than not that the committee will engage in future acts of
    sexual violence. The court's conclusion that the answer to this
    inquiry falls within the purview of the factfinder does not mean
    this statutory element disappears.
    20
    No.         2018AP2104
    within the purview of the factfinder, expert testimony on the
    third element may inform the factfinder's decision but it is not
    necessary to conclude that a person is sexually violent.
    B. Sufficiency-of-the-Evidence in Chapter 980 Appeals
    ¶30    Stephenson next asks us to overrule Curiel and depart
    from the sufficiency-of-the-evidence standard of review courts
    have been using for over 20 years.                    Under Curiel, appellate
    courts review Chapter 980 cases by asking whether "the evidence,
    when viewed most favorably to the state and [the commitment], is
    so insufficient in probative value and force that it can be said
    as a matter of law that no trier of fact, acting reasonably,
    could   have     found      [the    person       sexually     violent]        beyond        a
    reasonable doubt" at an initial commitment trial and by "clear
    and   convincing     evidence"      at    a     discharge    trial.          See     In    re
    Commitment     of   Curiel,    
    227 Wis. 2d 389
    ,       ¶52,   
    597 N.W.2d 697
    (citation     omitted);      Wis.    Stat.       §§ 980.05(3)      (at       an    initial
    commitment     trial,    the   State      must    prove     "beyond      a   reasonable
    doubt" that the individual is a sexually violent person) and
    980.09(3) (at a discharge trial, the State must prove "by clear
    and convincing evidence" that the individual still meets the
    criteria for commitment as a sexually violent person).                                 This
    sufficiency-of-the-evidence test is the same standard that we
    apply   in      reviewing      criminal         convictions.             Curiel,          
    227 Wis. 2d 389
    , ¶53.        Stephenson asks us to jettison this standard
    and instead apply independent review to whether the evidence
    satisfied     the   legal    standard      for    dangerousness.             We    see     no
    reason to do so.
    21
    No.   2018AP2104
    ¶31     In Curiel, the court concluded that, because Chapter
    980    proceedings         "share[]     many       of        the    same        procedural     and
    constitutional            features     present      in        criminal           prosecutions,"
    courts must apply the criminal standard of review to Chapter 980
    cases.
    Id., ¶54.
          Although it is true that Curiel partly relied
    upon a now-repealed statute to support its holding,12 many of the
    same rights recognized for criminal defendants continue to apply
    to committees in Chapter 980 proceedings.                               As provided by Wis.
    Stat. §§ 980.03(2) and (3), sexually violent offenders have the
    right to remain silent, to be provided with counsel, to request
    jury    trials      at     initial    commitment,            to    have    the     State     prove
    initial commitment "beyond a reasonable doubt," and to present
    and cross-examine witnesses.               Like criminal trials, Chapter 980
    proceedings         also     demand    that      the         State       turn     over     "[a]ny
    exculpatory evidence" which may inform a committee's right to
    discharge.           Wis.     Stat.    § 980.036(2)(j).                    Indeed,       although
    criminal trials and Chapter 980 proceedings possess important
    differences         (e.g.,     the      latter          is        not     for     purposes      of
    punishment), their relevant procedures are decidedly analogous——
    a     fact     properly      recognized       by        Curiel.            If     Chapter      980
    proceedings         and     criminal    actions          "parallel"         each       other    in
    substantive respects, as Curiel noted, then it only makes sense
    that        these   cases     have     mirroring             standards          for    reviewing
    Wisconsin Stat. § 980.05(1m) has since been legislatively
    12
    repealed.  See 2005 Wis. Act 434 §§ 101, 131(1). This statute

    defendant in a criminal proceeding are available to the

    ¶32   In asking this court to uproot established case law,
    Stephenson omits any discussion of Wisconsin's commitment to the
    doctrine of stare decisis.            This court respects the doctrine of
    stare decisis and will not overturn precedent absent a "special
    justification."         State   v.    Roberson,

    undermined the rationale behind the decision; (2) there is a
    need to make a decision correspond to newly ascertained facts;
    (3) there is a showing that the precedent has become detrimental
    to coherence and consistency in the law; (4) the prior decision
    is     'unsound    in   principle';        or    (5)   the    prior    decision    is

    ¶33     At    no    point        does       Stephenson        grapple       with    these
    factors.       In    particular,         he       never        asserts    why    the     current
    standard is "unworkable" or "unsound," nor does he identify any
    newly-ascertained             facts     about          Chapter     980      proceedings       or
    inconsistencies          in    the     law        that    would     justify       overturning
    Curiel.       At best, Stephenson's argument impliedly invokes the
    first factor, based upon the state legislature's repeal of Wis.
    Stat.      § 980.05(1m)         years     after          the    Curiel      decision.         As
    previously      explained,        this        statutory         change    did     nothing     to
    undermine the rationale underlying the Curiel decision.                                  Chapter
    980   proceedings        have     much       in    common       with     criminal      actions,
    warranting analogous standards of review.                           While this court is
    not "barred from pursuing a sound and prudent course for the
    sake of upholding its prior precedent," Stephenson's failure to
    even mention the doctrine of stare decisis while urging us to
    upend      well-established           precedent         fatally     foils    his      argument.
    Johnson Controls, 
    264 Wis. 2d 60
    , ¶96.
    C.    The Evidence is Sufficient.
    ¶34     Stephenson further argues that, even without mandating
    expert testimony for the third element or overturning Curiel,
    the circuit court nonetheless lacked sufficient evidence to deny
    his motion for postcommitment relief or to find that he remained
    a sexually violent person.13              Again, we are not persuaded.
    Stephenson concedes that he has been previously convicted
    13
    of a sexually violent offense and that he suffers from a mental
    disorder that predisposes him to acts of sexual violence.
    24
    No.    2018AP2104
    ¶35     Applying the Curiel standard, we will not reverse an
    order denying a discharge motion based on insufficient evidence
    "unless the evidence, viewed most favorably to the state and
    [the   commitment],         is   so    insufficient        in   probative          value   and
    force that it can be said as a matter of law that no trier of
    fact, acting reasonably, could have found" the person sexually
    violent by "clear and convincing evidence" at a discharge trial.
    See Curiel, 
    227 Wis. 2d 389
    , ¶52 (citation omitted).                               The court
    of appeals correctly concluded that the evidence was more than
    sufficient to uphold the circuit court's denial of Stephenson's
    petition for discharge.
    ¶36     The   facts       of    this    case       disproportionately           weigh
    against Stephenson.             First, Stephenson's criminal history proves
    his    penchant      for    re-offending       in    a    sexually     violent       manner.
    From    2000    to     2007,     Stephenson        was    convicted     six        times   for
    violent sexual behavior against children.                       Some of these crimes
    occurred       while       he    was     on   probation         for    past        offenses.
    Furthermore, Stephenson's comments and conduct during his time
    in the treatment facility indicate he is still unable to control
    his behavior.          Stephenson repeatedly violated the rules of the
    treatment facility and, at least on one occasion, attempted to
    obtain   sexually-suggestive             clothing        that   he    knew    was    banned.
    When confronted with these indiscretions, Stephenson proceeded
    to concoct lies and exhibit anti-social behavior.
    ¶37     Moreover, the results of Stephenson's non-suppressed
    penile    plethysmograph          test    also      support     the    circuit       court's
    finding.        As Kolbeck testified, Stephenson became aroused by
    25
    No.       2018AP2104
    stimuli "depicting teenager coercive interactions" as well as by
    graphic     depictions     of    "victims         crying       or     in    some       form     of
    suffering."      In addition, Stephenson scored highly on measures
    of psychopathy, reflecting his propensity for exhibiting shallow
    affect,     grandiosity,        and     manipulation.               These        psychometric
    scores      correspond     to         Kolbeck's        personal            evaluations          of
    Stephenson, which show that he continually exhibited traits of
    impulsivity, irritability, deceitfulness, and lack of remorse.
    A   reasonable    factfinder          could    conclude,         as    did       the    circuit
    court, that Stephenson would, more likely than not, act upon his
    sexual urges if released into the community.
    ¶38    Perhaps most importantly, the circuit court afforded
    appropriate      weight    to     the        results       generated         by     Kolbeck's
    actuarial      instruments,       in        light     of      all     of     the       evidence
    presented.      While Kolbeck's conclusion that Stephenson posed a
    41 percent risk of being arrested and convicted of a crime of
    sexual      violence    falls      below       the       "more      likely         than       not"
    threshold,      the     statutory        inquiry         examines          the     likelihood
    Stephenson      would     commit       future        acts      of     sexual        violence,
    irrespective     of     whether        he     might      be     apprehended            for,     or
    convicted of, such crimes.              Taking into account the evidence as
    a whole, a reasonable factfinder could conclude that Stephenson
    met   the      "more     likely        than       not"        threshold          for      future
    dangerousness.          Given    that       Stephenson         continually          exhibited
    traits of manipulation and deceit, a factfinder could reasonably
    conclude that Stephenson's actual risk of committing future acts
    26
    No.    2018AP2104
    of sexual violence, while nonetheless evading the law, was "more
    likely than not."
    ¶39   Lastly,        Kolbeck's      testimony       was     sufficient          to
    establish the nexus between Stephenson's mental disorders and
    his   potential       for     recidivism.          In    particular,          although
    Stephenson's Alcohol Abuse Disorder was then in remission given
    his confinement, Stephenson expressed a willingness to engage in
    "social drinking" if released into the community——a troubling
    statement for an individual who has "never committed a [sexual
    assault]    sober."         Moreover,   Kolbeck     stated      that    Stephenson's
    personality disorder "has a direct causal connection to [his]
    sexually    violent        behaviors     in   the       community"——an         equally
    disconcerting      observation       considering    that     Stephenson's        anti-
    social    traits    were     "still     active."        Given    these       facts,    a
    reasonable factfinder could conclude, as the circuit court did,
    that Stephenson would likely exhibit behaviors corresponding to
    these disorders and thereby pose a danger to the community.
    IV.    CONCLUSION
    ¶40   We   conclude      the    court   of    appeals      did    not    err    in
    upholding    the      circuit     court's     order      denying        Stephenson's
    petition for discharge from his Chapter 980 commitment.                               We
    reject all three of Stephenson's arguments.                  First, we hold the
    State is not required to present expert testimony to prove that
    a person is dangerous because his mental disorder makes it more
    likely than not that he will re-offend in a sexually violent
    manner.     The statutes do not require expert testimony on that
    element and we decline to create a rule not set forth in the
    27
    No.     2018AP2104
    text.    Second, we reaffirm the sufficiency-of-the evidence test
    articulated in Curiel as the appropriate standard of review for
    challenges to a Chapter 980 commitment.            Finally, our review of
    the record reveals overwhelming evidence from which a reasonable
    factfinder could have found that Stephenson continues to satisfy
    the definition of a "sexually violent person."              Accordingly, we
    affirm the decision of the court of appeals.
    By    the   Court.—The   decision   of   the    court   of     appeals   is
    affirmed.

    ¶41        ANN    WALSH        BRADLEY,        J.         (dissenting).              In    its
    application, Chapter 980 of the Wisconsin Statutes rides on the
    cusp        between         constitutionality                and         unconstitutionality.
    Although civil in nature, it gives the government power to lock
    up    individuals          indefinitely——including                    for   life——even       though
    they       have    already        completed         their     criminal        sentence.           All
    recognize that a significant liberty interest is at stake here.
    ¶42        In    order    to    ensure       that     Chapter        980    falls    on    the
    constitutional             side       of      the     divide,           enhanced         procedural
    safeguards are afforded to respondents.                                 Rather than applying
    the rules that normally attend a civil law proceeding, some
    criminal          law    procedural         safeguards           are     instead     applied      to
    provide      added       protections        in      order    to       survive      constitutional
    challenges.
    ¶43        The majority opinion undermines this delicate balance
    in    two    ways.         First,      it     erroneously             determines     that    expert
    testimony is not required to establish the causal link that Wis.
    Stat. § 980.01(7) requires:                    that the individual is more likely
    than not to engage in future acts of sexual violence because of
    the    diagnosed          mental      disorder.             In    reaching         its   erroneous
    determination,            the     majority          either       ignores      or     misconstrues
    precedent         related       to    the     necessity          of    expert      testimony      and
    effectively collapses the elements for determining a sexually
    violent person from three to two.
    ¶44        Additionally, the majority errs by perpetuating the
    Curiel1      standard       of       review      framework.             Under      the    guise   of
    State v. Curiel, 
    227 Wis. 2d 389
    , 416-417,

    acknowledging          the     need        for   enhanced       procedural           safeguards
    available     to       Chapter       980    respondents,       the        majority       actually
    leaves respondents with diminished protection.                               The standard of
    review that it applies saddles the respondent with a nearly
    insurmountable burden to overcome when reviewing the sufficiency
    of the evidence.
    ¶45   By examining the causal requirement set forth in Wis.
    Stat. § 980.01(7), and in light of what United States Supreme
    Court precedent demands as well as what our Wisconsin precedent
    and statutes require, I arrive at a conclusion contrary to that
    of the majority.             I determine that due process demands, and our
    precedent        and     statutes          require,     that        expert        testimony     be
    presented     in       order    to    establish       the     causal       link     between     an
    individual's mental disorder and the risk that the individual is
    more   likely      than        not    to     engage    in     future       acts      of   sexual
    violence.
    ¶46   I     further           determine         that     when         reviewing          the
    sufficiency        of        the      evidence        on      the     issue         of    future
    dangerousness, appellate courts must apply a two-step standard
    of review that is applied in other cases of constitutional fact.
    When   applying         this       framework,        questions       of    historical         fact
    should be accorded deference, while the question of whether the
    facts meet a required legal standard presents a question of law
    that   is    subject      to       independent       appellate       review.         I    see   no
    justification (and the majority offers none) for applying a more
    onerous standard of review in Chapter 980 civil commitments than
    is applied in Chapter 51 civil commitments, which adhere to the
    2
    No.    2018AP2104.awb
    two-step constitutional fact standard of review.                                See Langlade
    Cnty. v. D.J.W., 
    2020 WI 41
    , ¶47, 
    391 Wis. 2d 231
    , 
    942 N.W.2d 277
    .     In fact, any textual justification for reviewing Chapter
    980    cases    under       a   different      standard      than    Chapter        51   cases
    disappeared with the repeal of Wis. Stat. § 980.05(1m).
    ¶47     Accordingly, I respectfully dissent.
    I
    ¶48     Wisconsin        Stat.    § 980.01(7)      contains         three     elements
    that the State must prove in order to continue Stephenson's
    Chapter 980 commitment:                 (1) that he has been convicted of a
    sexually violent offense; (2) that he suffers from a mental
    disorder;      and     (3)      that    he    is    dangerous    because          his    mental
    disorder makes it more likely than not that he will engage in
    future acts of sexual violence.                     § 980.01(7).       At issue here is
    whether expert testimony is necessary for the State to prove the
    required causal link set forth in the third element.
    ¶49     At the discharge trial, both the State's expert and
    Stephenson's       expert       agreed       that   Stephenson       did    not     meet    the
    third element for continued commitment as a sexually violent
    person.      The State introduced testimony from Dr. Don Kolbeck, a
    psychologist,         to     establish        the   second     element          necessary    to
    commit      Stephenson:           that       Stephenson      suffers       from     a    mental
    disorder.       See Wis. Stat. § 980.01(7).                    Dr. Kolbeck testified
    that   he    had     diagnosed         Stephenson     with    two    qualifying          mental
    disorders:           (1)     Other      Specified     Personality          Disorder,       with
    antisocial       and       borderline        features;    and       (2)    Alcohol       Abuse
    Disorder.       Majority op., ¶8.
    3
    No.     2018AP2104.awb
    ¶50    In reaching his opinion that Stephenson did not meet
    the criteria for the third element necessary to sustain his
    continued       commitment,      Dr.     Kolbeck       discussed         Stephenson's
    progress       during   his     course     of    treatment        along     with    his
    performance on two actuarial risk instruments:                      the Static-99R
    and the Violence Risk Scale-Sex Offense Version (VRS-SO).2                          The
    test       results   indicated    that       Stephenson     had     a     41   percent
    probability of sexual re-offense.
    Id., ¶13.
           When called upon
    to give an opinion regarding the necessary third element, Dr.
    Kolbeck concluded based on Stephenson's progress in treatment
    and test results that he did not satisfy the more likely than
    not standard for continued commitment.                     Id.;    see     Wis. Stat.
    § 980.01(1m) (defining "likely" as "more likely than not").
    ¶51    Stephenson      introduced       his   own   expert       witness,    Dr.
    Courtney Endres, who disagreed with the State's expert as to the
    second element and concluded that Stephenson "no longer [met]
    the criteria for a mental disorder as defined under Wisconsin
    Chapter 980."        Majority op., ¶14.          However, she agreed with Dr.
    Kolbeck that Stephenson was unlikely to sexually re-offend and
    thus no longer met the statutory criteria for commitment as a
    sexually      violent   person.
    Id. Endres used the
        same   risk
    assessment instruments employed by Dr. Kolbeck and determined
    that Stephenson evinced a 10 percent risk of re-offense over
    Dr. Kolbeck testified that the VRS-SO provides the best
    2
    framework for assessing dynamic risk among the available tools.
    Furthermore, he explained that it provides a meaningful
    quantification of risk reduction as a result of treatment
    progress.

    five years and 17 percent risk over ten years.
    Id. Despite both experts
    testifying that Stephenson did not meet the third
    element necessary for recommitment, the circuit court denied the
    discharge petition.
    Id., ¶16.
    II
    ¶52    With the relevant testimony in hand, I begin with an
    examination of the of language of Wis. Stat. § 980.01(7).                             It
    provides:        "'Sexually violent person' means a person who has
    been convicted of a sexually violent offense . . . , and who is
    dangerous because he or she suffers from a mental disorder that
    makes it likely that the person will engage in one or more acts
    of sexual violence."
    ¶53    Importantly, the language of the statute requires that
    there   must     be   a   causal   nexus      between     the     diagnosed      mental
    disorder and the likelihood of sexual re-offense.                         That is, in
    order to be a "sexually violent person" within the meaning of
    Wis. Stat. § 980.01(7), individuals must be more likely than not
    to engage in future acts of sexual violence because they suffer
    from a particular mental disorder.              See Wis. Stat. § 980.01(1m).
    ¶54    Thus, the issue presented here is whether the answers
    to the following questions are within the common knowledge of
    the    average    lay     person   or   do     they     require    some        technical
    knowledge or expertise in order to establish the third element
    necessary for Stephenson's continued commitment.                         The questions
    are:
    Does    the    mental   illness        ("other    specified         personality
    disorder, with antisocial and borderline features") cause
    5
    No.    2018AP2104.awb
    Stephenson to be more likely than not to engage in future
    acts of sexual violence?
    Or, in the alternative, does the mental illness ("alcohol
    abuse disorder") cause Stephenson to be more likely than
    not to engage in future acts of sexual violence?
    ¶55   Although    we   engage    in     pages    of    analysis    and   legal
    exegesis, the issue presented is really quite simply addressed.
    Yes, expert testimony is required.             Why?        Because the answers
    call for technical knowledge and expertise beyond that of the
    average lay person.    Such a conclusion is supported by the plain
    language of Wis. Stat. § 907.02(1).           This subsection states:
    If   scientific,   technical,   or  other   specialized
    knowledge will assist the trier of fact to understand
    the evidence or to determine a fact in issue, a
    witness qualified as an expert by knowledge, skill,
    experience,   training,   or  education,  may   testify
    thereto in the form of an opinion or otherwise, if the
    testimony is based upon sufficient facts or data, the
    testimony is the product of reliable principles and
    methods, and the witness has applied the principles
    and methods reliably to the facts of the case.
    ¶56   Wisconsin courts have long held that expert testimony
    is required "concerning matters involving special knowledge or
    skill or experience upon subjects which are not within the realm
    of the ordinary experience of mankind, and which require special
    learning, study and experience."             Cramer v. Theda Clark Mem'l
    Hosp., 
    45 Wis. 2d 147
    , 150, 
    172 N.W.2d 427
    (1969).                     This case
    presents such a matter.
    ¶57   The   testimony    at     issue    in     this    case    involves   the
    interpretation of diagnostic tests and the application of data,
    6
    No.    2018AP2104.awb
    principles, and methods to the facts of the case.                      Ultimately,
    it requires a determination of whether a specific mental illness
    will   more    likely    than   not   cause    an   individual    to    engage   in
    future acts of sexual violence.               This is hardly the daily fare
    of the average lay person.            Expert testimony on these subjects
    is required, as they concern areas of specialized information
    outside the realm of ordinary knowledge.
    ¶58    Such a conclusion is supported by instructions on this
    court's website when it advises litigants that even in small
    claims   cases    where    special     knowledge     or   skill    is   involved,
    expert testimony is required to prove the case.                 For example, we
    instruct litigants that in a small claims motor vehicle faulty
    repair case that a "full-time mechanic or a repair person" may
    be sufficient to qualify as the expert and that "[h]aving the
    expert witness testify in person is almost always necessary"
    (emphasis      added).    "Basic      Guide    to   Wisconsin      Small    Claims
    Actions",                       https://www.wicourts.gov/formdisplay/SC-
    6000V_instructions.pdf?formNumber=SC-
    6000V&formType=Instructions&formatId=2&language=en, at 10 (Nov.
    2019).
    ¶59    For heaven's sake, if this court acknowledges the need
    for an expert to testify even in a small claims motor vehicle
    faulty repair case, then surely an expert is needed to opine on
    the above technical question.            Such an inquiry is firmly within
    the realm of expert testimony.
    ¶60    Nevertheless, the State advances that expert testimony
    is not required to prove that a person's mental disorder will
    7
    No.    2018AP2104.awb
    more likely than not cause the person to engage in future acts
    of   sexual     violence.           According        to       the       State,      the    common
    understanding of the jury is sufficient to evaluate the required
    causal link between the mental disorder and the likelihood of
    future sexually violent acts.              The majority follows suit.
    ¶61     In the majority's view, by testifying to the second
    element, the presence of a mental disorder, an expert "lays the
    foundation for any forthcoming evidence pertinent to the third
    element."       Majority       op.,    ¶29.          In       essence,        the    majority's
    interpretation of Wis. Stat. § 980.01(7) erroneously collapses
    the required statutory elements from three to two and thereby
    renders the third element mere surplusage.                                This is quite a
    leap.   Our case law is clear that, "[s]tatutory language is read
    where possible to give reasonable effect to every word, in order
    to avoid surplusage."           State ex rel. Kalal v. Cir. Ct. for Dane

    , 
    681 N.W.2d 110
    .
    ¶62     Compounding      its    error     in    failing           to    require       expert
    testimony      on   the    third      element,        the          majority        conflates    a
    predisposition for acts of sexual violence with a likelihood
    that such acts will be committed.                    In the majority's view, when
    an   expert    testifies       to    the   presence           of    a    qualifying        mental
    disorder, they additionally lay the foundation for the third
    element,    whether       an   individual       has       a    likelihood           of    sexually
    violent re-offense.            Majority op., ¶28.
    ¶63     But the majority fails to recognize the distinction
    between predisposition and probability.                            Although a respondent
    may have a predisposition toward acts of sexual violence, the
    8
    No.    2018AP2104.awb
    third element of the Chapter 980 analysis is concerned with the
    probability         that       sexually    violent         conduct       will    occur          in   the
    future.
    ¶64     By    conflating          the    second      element       of     predisposition
    with    the     third          element    of    probability,         the        majority         risks
    raising due process concerns.                    The majority's belief that a lay
    factfinder can independently discern the required causal link is
    little more than a commentary on the ability of lay factfinders
    to determine general dangerousness.                         While lay factfinders may
    be     competent          to     examine       varied       facts    to        assess       general
    dangerousness, that is not at issue in this case.
    ¶65     Chapter 980 cases present an inquiry different than
    the general criminal law inquiry of future dangerousness and due
    process concerns place different demands.                           In Chapter 980 cases,
    "due process requires that the nature and duration of commitment
    bear    some       reasonable       relation         to    the   purpose        for       which      the
    individual is committed."                  State v. Post, 
    197 Wis. 2d 279
    , 313,
    
    541 N.W.2d 115
    (1995) (citation omitted).                               Chapter 980 passes
    due    process       muster       specifically        because       it    requires          a    nexus
    between a respondent's mental disorder and the probability of
    future    dangerousness.                 State     v.      Laxton,       
    2002 WI 82
    ,        ¶22,
    
    254 Wis. 2d 185
    , 
    647 N.W.2d 784
    .                           In other words, the mental
    disorder must make the individual dangerous in a specific way as
    opposed       to     the       general     dangerousness          that      accompanies              any
    analysis of potential recidivism.                         See Kansas v. Hendricks, 
    521 U.S. 346
    ,       358    (1997).          Such      an    inquiry        mandates         special
    expertise.

    ¶66    Stephenson cites also to two Wisconsin cases for the
    proposition that expert testimony must be presented when making
    determinations about probability of sexually violent re-offense.

    the causal link between an individual's mental disorder and the
    conduct at issue.

    suffered from obsessive compulsive disorder (OCD), the symptoms
    of which include the high reactive behaviors that occasioned the
    termination.
    Id., ¶2.
        At issue in the case was whether expert
    testimony was required to establish the causal link between the
    employee's mental disorder and the conduct for which he was
    fired.
    Id., ¶11. ¶68
       The court determined that expert testimony was indeed
    required to establish that conduct which formed the basis for
    the   employment      termination      was    caused     by   the     employee's
    disability.
    Id., ¶¶16-17.
          Additionally, the court noted that,
    "[i]nferring the required causal link from the evidence in the
    present     record,   without     expert     testimony   on   the     issue,   is
    speculation, not the drawing of a reasonable inference to which
    we must defer."
    Id., ¶25. 10
                                                                        No.    2018AP2104.awb
    ¶69     Second, B.P. involved a termination of parental rights
    due to abandonment of a child.             B.P., 
    386 Wis. 2d 557
    , ¶2.                   B.P.
    raised    a   good    cause    defense    to    allegations        that    he     had    not
    visited or communicated with his child for a six-month period by
    claiming that his mental health diagnoses caused him to do so.
    Id., ¶43.
         The court concluded that B.P. needed expert testimony
    to   relate    his    factual    assertions       to    his    good     cause     defense
    because making such a causal link was outside of the ordinary
    experience of humankind.
    Id., ¶¶48-49.
             Thus, in both Wal-Mart
    and B.P., the court reasoned that the establishment of a causal
    nexus between their conduct and a mental illness required the
    submission of expert testimony.
    ¶70     The    majority    attempts       to     distinguish        these       cases,
    contending that Stephenson's case is about future actions, not
    past ones.         Majority op., ¶25.          True enough, but why does this
    matter?       If    expert    testimony    is    needed       to   look    at     a    fully
    developed fact record and make causal links with the benefit of
    20/20 hindsight, then surely no less can be demanded when the
    trier of fact looks forward on the same basis.
    III
    ¶71     The majority errs next in its discussion of Curiel and
    the sufficiency of the evidence standard in Chapter 980 cases.
    It   perpetuates      the     Curiel   criminal      standard      of     review       under
    which    appellate      courts    review       Chapter    980      cases    by        asking
    whether, "the evidence, when viewed most favorably to the state
    and [the commitment], is so insufficient in probative value and
    force that it can be said as a matter of law that no trier of
    11
    No.    2018AP2104.awb
    fact . . . could have found [the person sexually violent] beyond
    a reasonable doubt . . . ."                     Majority op., ¶30; see State v.
    Curiel, 
    227 Wis. 2d 389
    , 416-17, 
    597 N.W.2d 697
    (1999).
    ¶72    On review, Curiel advocated a two-step constitutional
    fact   standard      of     review        with      facts    being      reviewed    under   a
    deferential standard and the application of facts to the legal
    standard being reviewed independently.                        Opposing this framework,
    the State asserted that the criminal standard of review should
    be applied.
    ¶73    The   Curiel       court        applied      the    criminal     standard     of
    review    without        engaging        in    much    analysis.         It    decried   that
    although each party offered a standard of review, neither party
    gave   any    rationale         to   support         its    position:         "[a]side   from
    describing these competing standards of review, neither party
    provides reasons why one or the other standard of review is
    appropriate for ch. 980 proceedings."                            
    Curiel, 227 Wis. 2d at 416-17
    .      The Curiel court opted for the criminal law standard of
    review.      At the time, the Curiel court's approach may have found
    support      in   Wis.    Stat.      §    980.05(1m)        (1995-96)      which    provided
    that, "[all] constitutional rights available to a defendant in a
    criminal proceeding are available to the [individual subject to
    commitment proceedings]."                     Majority op., ¶31 n.12.               However,
    Wis. Stat. § 980.05(1m) was repealed in 2005.                           See 2005 Wis. Act
    434, § 101.          Thus, any textual support for applying a more
    onerous      standard      of    review        in     Chapter     980   cases     than   that
    applied in Chapter 51 cases disappeared with the repeal of the
    statute.
    12
    No.    2018AP2104.awb
    ¶74      The majority relies solely on Curiel to support its
    conclusion.       It opines that because Chapter 980 affords enhanced
    procedural       safeguards          similar       to     those    found     in       criminal
    prosecutions, such as the right to counsel and the right to
    remain silent, it follows that respondents in Chapter 980 cases
    should    be    subject      to      the   criminal       standard   of     review.          See
    Majority       op.,   ¶31.        Therein      lies       the   Achilles     heel      of    the
    majority's analysis.
    ¶75      Rather than providing more protection to the Chapter
    980   respondent           in      order     to         successfully        straddle         the
    constitutional divide, the majority actually provides less.                                  The
    criminal        standard        of     review        is     more     onerous          than     a
    constitutional        fact        standard      of      review.        It    saddles         the
    respondent       in    a        Chapter     980         commitment     with       a     nearly
    insurmountable burden to overcome when reviewing the sufficiency
    of the evidence.
    ¶76      Adopting the two-part standard of review in Chapter
    980 cases is consistent with the way this court reviews civil
    commitment proceedings under Wis. Stat. § 51.20.                            Both focus on
    a determination of dangerousness.                    In Langlade County v. D.J.W.,
    this court concluded that "[a] determination of dangerousness is
    not a factual determination, but a legal one based on underlying
    facts."      
    391 Wis. 2d 231
    , ¶47.                 We concluded that the court of
    appeals erred for doing the very thing that the majority does
    today:      "applying the standard of review for findings of fact to
    a legal determination . . . ."
    Id. 13
                                                                   No.     2018AP2104.awb
    ¶77    There is no reason to apply different standards of
    review       to   assessments    of    the    sufficiency     of       evidence    of
    dangerousness in Chapter 51 civil commitment and Chapter 980
    civil     proceedings.          In    both,     the     commitment       implicates
    fundamental due process rights because both potentially result
    in a significant deprivation of liberty.                  Likely the majority
    proffers no reason justifying such disparate treatment because
    no reasonable explanation can be found.
    ¶78    I   conclude   that     evidence    supporting       a    finding    of
    dangerousness under Chapter 980 should be reviewed using the
    constitutional fact standard.            As explained above, due process
    concerns circumscribe commitments under Chapter 980 to persons
    who have a mental disorder that more likely than not will cause
    them to commit future acts of sexual violence.
    ¶79    The Chapter 980 context is best served by adopting
    this    two-part     standard   with    facts     being   reviewed       under    the
    clearly erroneous standard and the application of those facts to
    the     legal     standard   being     reviewed       independently.         As    we
    explained in       State v. Phillips, such an approach serves the
    interests of greater uniformity of application and clarity in
    the legal standard while taking into account the significant
    liberty interests at stake in these proceedings:
    [T]he principal reason for independent appellate
    review of matters of constitutional fact is to provide
    uniformity in constitutional decision-making.    It is
    the duty of the reviewing court to independently apply
    constitutional principles to the facts as found by the
    circuit court because the scope of constitutional
    protections, representing the basic value commitments
    of our society, cannot vary from trial court to trial
    court, or from jury to jury. In applying the skeletal
    14
    No.   2018AP2104.awb
    constitutional rule, appellate courts flesh out the
    rule and provide guidance to litigants, lawyers, and
    trial and appellate courts.
    State v. Phillips, 
    218 Wis. 2d 180
    , 194, 
    577 N.W.2d 794
    (1998)
    (internal citations and quotations omitted).
    ¶80   In sum, for the reasons set forth above, I determine
    that expert testimony is required to establish the causal link
    between an individual's mental disorder and the risk that the
    individual is more likely than not to engage in future acts of
    sexual violence.    Because no expert testimony was presented at
    Stephenson's   discharge   trial   to   support   this    requirement,     I
    conclude that the State failed to meet its burden of proof.
    Additionally, I determine that the two-step constitutional fact
    standard of review should be applied to sufficiency of evidence
    challenges in Chapter 980 proceedings.
    ¶81   Accordingly, I respectfully dissent.
    ¶82   I am authorized to state that Justice REBECCA FRANK
    DALLET joins this dissent.
