    A minor who is the subject of a wardship petition under Welfare and
    Institutions Code1 section 601 or 602 has, like an adult facing criminal
    prosecution, a due process right not to be tried while mentally incompetent.
    Section 709 establishes procedures for juvenile courts to follow so as to ensure
    that minors are not subject to adjudication while their competency is impaired.
    We decide two issues in this case; first, whether under section 709 a minor
    is presumed competent and bears the burden of proving otherwise by a
    preponderance of the evidence and, second, what is the proper standard for
    1       All further unlabeled statutory references are to the Welfare and Institutions
    Code.
    reviewing on appeal a challenge to the sufficiency of the evidence supporting the
    juvenile court‟s determination that the minor was competent to proceed.
    Section 709 is silent regarding the presumption of competency and
    allocation of the burden of proof, but we find that the most straightforward reading
    of the statute‟s text is that the provision contains an implied presumption of
    competency. This understanding of section 709 is further supported by the
    legislative materials surrounding that statute‟s enactment, which show that
    lawmakers intended the juvenile courts to continue to apply to minors the adult
    competency scheme‟s presumption of competency and allocation of the burden of
    proof to the party claiming incompetency.
    We conclude furthermore that, like a challenge to the sufficiency of the
    evidence supporting the verdict in an adult competency proceeding, a claim of
    insufficient evidence to support a juvenile court‟s determination in a competency
    proceeding is reviewed deferentially under the substantial evidence test. In the
    present matter, the evidence before the juvenile court consisted solely of the court-
    appointed expert‟s report and testimony, and the materials on which the expert
    based his opinion, that 16-year-old R.V. was incompetent to stand trial. In these
    circumstances, we review the juvenile court‟s determination by asking whether the
    weight and character of that evidence is such that the juvenile court could not
    reasonably have rejected it.
    Having viewed the evidence presented in the case in the light most
    favorable to the juvenile court‟s determination of competency, as we must,
    we nonetheless conclude that the court could not reasonably have rejected the
    qualified expert‟s compelling, well-supported, and unequivocal opinion that minor
    was not competent to proceed to trial.
    The Court of Appeal concluded, to the contrary, that the juvenile court‟s
    reasons for declining to accept the expert‟s opinion were supported by substantial
    2
    evidence in the record, and upheld the judgment below. Accordingly, the Court of
    Appeal‟s judgment is reversed.
    I. BACKGROUND
    On a weekday morning in March 2012, officers from the La Habra Police
    Department responded to a 911 call reporting that a juvenile was threatening
    family members with a knife. Jose Cruz, who resided with minor, minor‟s
    stepsibling, and minor‟s mother, told police that he had awakened minor for
    school around 7:00 a.m. Minor became angry and starting throwing things, saying
    he did not want to go to school. Cruz argued with minor, warning him that he was
    going to miss his bus. In response, minor clenched his fists and told Cruz, “I‟m
    going to fuck you up,” then continued to throw and kick things around the living
    room. When Cruz told minor to calm down, minor held out a knife and said he
    would kill Cruz if he called the police. According to Cruz, minor did not move
    toward him with the weapon.
    Minor‟s mother confirmed that minor had been throwing things around the
    living room, and told police that she saw him knock a small television set to the
    floor. According to minor‟s mother, minor moved from the living room to the
    bedroom and started yelling, “I want a house. I want my own space.” He warned
    his mother, “Don‟t come close to me. I have a knife.” Minor‟s mother saw that he
    had a small silver knife in his hand.
    Javier Naranjo, the family‟s landlord, also spoke with the officers. He told
    them that he had entered the residence after hearing the sound of something
    breaking and saw minor kick a DVD player in the living room. He also overheard
    minor arguing with Cruz and threatening to stab him with a knife. When Naranjo
    likewise told minor to calm down, minor threatened to kill him as well. Naranjo
    then saw minor go into his bedroom and stab a bed three times.
    3
    Minor complied with the officers‟ order to raise his hands in the air. As
    minor was being handcuffed, he mentioned that the knife, a multitool with a two-
    inch blade, was in his front right pocket. Minor explained to one of the officers
    that he was upset and trying to scare his mother, and indicated that he had trouble
    with his parents. According to that officer‟s report, minor appeared to have a
    difficult time understanding the officer‟s questions and seemed confused about the
    incident.
    All three witnesses reported to police that minor had psychological
    problems. His mother indicated that for the past four weeks he had not taken his
    medication, Abilify. Cruz explained that minor is “different every day” and “with
    each episode he gets worse.” Minor was taken into custody and transported to a
    juvenile detention facility.
    Three days after the incident, the Orange County District Attorney filed a
    section 602 petition to declare minor a ward of the juvenile court. The petition
    alleged that minor committed two misdemeanor counts of brandishing a deadly
    weapon (Pen. Code, § 417, subd. (a)(1)), and one misdemeanor count of
    vandalism (Pen. Code, § 594, subds. (a), (b)(2)(A)). About three weeks later,
    defense counsel expressed a doubt regarding minor‟s competency to stand trial. In
    accordance with statutory procedures, the court determined there was substantial
    evidence raising a doubt as to minor‟s competency, suspended proceedings, and
    appointed a forensic psychologist, Haig J. Kojian, Ph.D., to evaluate minor. (See
    § 709, subd. (a).) Although the court also ordered minor released on the home
    supervision program pending the competency hearing, minor was returned to
    juvenile detention 10 days later for violating the conditions of his release.
    Dr. Kojian‟s nine-page report concluded that minor presently was not
    competent to stand trial. Although defense counsel offered to submit the question
    of competency on the basis of Dr. Kojian‟s written report, the prosecutor
    4
    expressed concern that Dr. Kojian had not administered any diagnostic tests to
    minor and requested a hearing at which Dr. Kojian could be questioned. The court
    granted the request.
    At the hearing held one week later, Dr. Kojian explained, consistently with
    his written report, the basis for his conclusion that minor was not competent to
    stand trial. At the conclusion of the hearing, the court expressed its view that the
    law presumes minor is competent and places on him the burden of proving
    incompetency by a preponderance of the evidence. The court then ruled that
    minor had not met his burden of proof, found minor competent to stand trial, and
    ordered the reinstatement of proceedings.
    Immediately after the court‟s competency determination, minor waived his
    various rights and entered a “slow plea,” submitting the matter to the court for
    adjudication based on the police report. The court found the allegations in the
    wardship petition to be true, declared minor a ward of the juvenile court, and
    placed him on probation.
    The Court of Appeal affirmed the judgment. It first agreed with the
    juvenile court that a minor is presumed competent and bears the burden of proving
    by a preponderance of the evidence that he or she is not competent to be
    adjudicated under the juvenile court law. Applying a substantial evidence
    standard of review, the Court of Appeal upheld the juvenile court‟s determination
    that minor was competent to proceed and affirmed the judgment.
    This court granted minor‟s petition for review.

    II. DISCUSSION
    A. Presumption of competency and allocation of the burden of proof in
    proceedings to determine juvenile competency under section 709
    We briefly review the law regarding competency to stand trial and some of
    the legal developments that preceded the enactment of section 709. This history
    guides our interpretation of the statute.
    1. Overview of the law predating section 709
    The constitutional right to due process of law prohibits the trial of a
    mentally incompetent criminal defendant. (People v. Medina (1990) 
    51 Cal. 3d 870
    , 881; Drope v. Missouri (1975) 
    420 U.S. 162
    , 172-173.) Due process
    principles further require trial courts to employ procedures to guard against the
    trial of an incompetent defendant. (People v. Hale (1988) 
    44 Cal. 3d 531
    , 539;
    People v. Pennington (1967) 
    66 Cal. 2d 508
    , 518; Pate v. Robinson (1966) 
    383 U.S. 375
    , 377.) Under Dusky v. United States (1960) 
    362 U.S. 402
    (Dusky), the
    inquiry into a defendant‟s competency to proceed focuses on whether the
    defendant “ „has sufficient present ability to consult with his lawyer with a
    reasonable degree of rational understanding — and . . . a rational as well as factual
    understanding of the proceedings against him.‟ ” (Id. at p. 402 (the Dusky
    standard).)
    The constitutional prohibition against trial of an incompetent defendant and
    the requirement of procedures to prevent trial from occurring under those
    circumstances are mirrored in Penal Code section 1367 et seq. Similar to the
    Dusky standard, state law provides that a defendant is incompetent if he or she “is
    unable to understand the nature of the criminal proceedings or to assist counsel in
    the conduct of a defense.” (Pen. Code, § 1367, subd. (a).)
    Under statutory procedures for determining a criminal defendant‟s
    competency to stand trial, the defendant is presumed competent unless proved
    6
    incompetent by a preponderance of the evidence. (Pen. Code, § 1369, subd. (f);
    People v. 
    Medina, supra
    , 51 Cal.3d at p. 881.) On its face, the statutory scheme
    does not expressly impose the burden of proof on any specific party. Rather, the
    presumption of competency operates to place the burden of proof on the party
    claiming the defendant is incompetent. (See Evid. Code, §§ 605, 606; People v.
    Rells (2000) 
    22 Cal. 4th 860
    , 867, 868.)
    Penal Code section 1367 et seq., by its terms, applies to criminal
    prosecutions, not to juvenile court proceedings. In James H. v. Superior Court
    (1978) 
    77 Cal. App. 3d 169
    (James H.), however, the Court of Appeal held that the
    juvenile had a due process right to a competency adjudication as part of a section
    707, subdivision (b), proceeding to determine his fitness to be dealt with under the
    juvenile court law. (James 
    H., supra
    , at pp. 174-176.) The Court of Appeal
    reasoned that its conclusion was compelled, in part, by the high court‟s decision in
    In re Gault (1967) 
    387 U.S. 1
    , which held that a juvenile facing possible loss of
    liberty pending the outcome of a delinquency proceeding is entitled to the same
    “ „essentials of due process and fair treatment‟ ” (id. at p. 30) as defendants in
    adult criminal proceedings, including the right to effective counsel. (James 
    H., supra
    , at pp. 173-174; see In re 
    Gault, supra
    , at pp. 30-31, 35-42.)
    The Court of Appeal in James H. acknowledged the absence of existing
    statutory procedures for juvenile competency determinations. It concluded,
    however, that the juvenile court has inherent authority to conduct such hearings.
    (James 
    H., supra
    , 77 Cal.App.3d at pp. 175-176.) As the Court of Appeal
    observed, juvenile courts routinely improvise procedures to meet changing
    constitutional requirements while awaiting legislative clarification. (Id. at p. 176.)
    In this regard, at the time of the James H. decision, juvenile courts appear to have
    been making use of adult competency procedures in wardship proceedings under
    sections 601 and 602. (See, e.g., In re Ramon M. (1978) 
    22 Cal. 3d 419
    , 430,
    7
    fn. 14 [noting the People‟s concession that “the protective reach of Penal Code
    section 1368 extends to section 602 proceedings in juvenile court”].) The
    James H. decision likewise fashioned a Penal Code section 1368-like procedure
    for juvenile courts making competency determinations. The procedure required
    the court to suspend proceedings and conduct a competency hearing in the event it
    entertained a doubt regarding the juvenile‟s capacity or ability to cooperate with
    his or her attorney. With regard to the definition of incompetence, the James H.
    decision advised juvenile courts either to borrow the formulation in Penal Code
    section 1367 or to use the test set forth in the high court‟s decision in 
    Dusky, supra
    , 
    362 U.S. 402
    . (James 
    H., supra
    , at pp. 176-177; see Timothy J. v. Superior
    Court (2007) 
    150 Cal. App. 4th 847
    , 857-858 (Timothy J.).) The decision did not
    address the presumption of competency or burden of proof.
    In 1999, the Judicial Council added former rule 1498 to the California
    Rules of Court in order to establish statewide procedures for conducting a hearing
    to determine the competency of a juvenile subject to a wardship proceeding under
    section 601 or 602. The rule was intended to, and largely did, conform to the
    procedures described in the James H. decision and established as the definition of
    competency an abbreviated version of the Dusky standard.2 (Advisory Com. com.,
    23 pt. 3 West‟s Ann. Codes, Rules (2005 ed.) foll. rule 1498(d), p. 630; see
    Timothy 
    J., supra
    , 150 Cal.App.4th at pp. 858, 859.) It also authorized, but did not
    require, the court to appoint an expert to evaluate the juvenile‟s competency to
    proceed. (Cal. Rules of Court, former rule 1498(d)(1).)
    2       Effective January 1, 2007, California Rules of Court, former rule 1498 was
    amended in ways not relevant here and was renumbered rule 5.645. The portion
    of the renumbered rule relating to competency to stand trial appears in rule
    5.645(d).
    8
    Subsequent to the adoption of California Rules of Court, former rule 1498,
    the Court of Appeal in Timothy 
    J., supra
    , 
    150 Cal. App. 4th 847
    , held that the rule
    permitted a finding of incompetence arising from the minor‟s developmental
    immaturity. This construction of former rule 1498 distinguished the juvenile
    competency standard from Penal Code section 1367, subdivision (a), which
    requires a showing that the adult defendant‟s incompetence arose from either a
    mental disorder or developmental disability. (Timothy 
    J., supra
    , at pp. 858-861.)
    In Tyrone B. v. Superior Court (2008) 
    164 Cal. App. 4th 227
    (Tyrone B.), the Court
    of Appeal held that, notwithstanding the permissive language of the rule, the
    juvenile court must appoint an appropriate expert to evaluate the minor when the
    minor‟s counsel expresses a doubt regarding the minor‟s competency and the court
    finds substantial evidence raises a doubt in this regard. (Id. at p. 231 [construing
    rule 5.645(d), the current version of the rule].)
    A decade after the adoption of California Rules of Court, former rule 1498,
    the Legislature enacted section 709, codifying some of the standards and
    procedures that had been established in the rules of court, and modifying or adding
    others consistently with the holdings in decisions such as Timothy 
    J., supra
    , 
    150 Cal. App. 4th 847
    , and Tyrone 
    B., supra
    , 
    164 Cal. App. 4th 227
    . The Legislature
    also provided for the Judicial Council‟s continued involvement in this area by
    expressly delegating to that body the task of developing and adopting rules
    regarding the special qualifications an expert must possess in order to be appointed
    by the court to evaluate a minor‟s competency. (Stats. 2010, ch. 671, § 1.)
    2. Section 709
    Section 709 begins by describing the mechanisms by which the issue of
    competency arises. The statute provides in relevant part that “[d]uring the
    pendency of any juvenile proceeding, the minor‟s counsel or the court may
    9
    express a doubt as to the minor‟s competency.” (§ 709, subd. (a).) Like the
    juvenile competency procedures adopted in the Rules of Court, section 709 uses
    the Dusky standard to define competency. The statute does not employ an
    abbreviated form of the standard, however, and establishes the inquiry as whether
    the minor “lacks sufficient present ability to consult with counsel and assist in
    preparing his or her defense with a reasonable degree of rational understanding, or
    lacks a rational as well as factual understanding, of the nature of the charges or
    proceedings against him or her.” (§ 709, subd. (a).)
    The statute further provides that if the court finds “substantial evidence
    raises a doubt as to the minor‟s competency,” the proceedings must be suspended
    and the court must order a hearing to determine the minor‟s competency. (§ 709,
    subds. (a), (b).) Toward that end, the court is required to “appoint an expert to
    evaluate whether the minor suffers from a mental disorder, developmental
    disability, developmental immaturity, or other condition and, if so, whether the
    condition or conditions impair the minor‟s competency.” (§ 709, subd. (b).) In
    order to qualify for appointment under section 709, the expert must be proficient
    in child and adolescent development and familiar with the applicable standards
    and criteria for evaluating competency. As mentioned above, the statute assigns to
    the Judicial Council the responsibility for developing and adopting rules to
    implement such requirements. (Id., subd. (b).)
    Section 709 then describes how the court should proceed, depending on the
    outcome of the competency determination. “If the minor is found to be
    incompetent by a preponderance of the evidence,” the proceedings remain
    suspended for a reasonable period of time until it can be determined whether there
    is a substantial probability that the minor will attain competency in the foreseeable
    future while the court still retains jurisdiction. (§ 709, subd. (c).) If, on the other
    10
    hand, “the minor is found to be competent, the court may proceed commensurate
    with the court‟s jurisdiction.” (§ 709, subd. (d).)3
    3       Section 709, subdivisions (a) through (e), reads in full: “(a) During the
    pendency of any juvenile proceeding, the minor‟s counsel or the court may
    express a doubt as to the minor‟s competency. A minor is incompetent to proceed
    if he or she lacks sufficient present ability to consult with counsel and assist in
    preparing his or her defense with a reasonable degree of rational understanding, or
    lacks a rational as well as factual understanding, of the nature of the charges or
    proceedings against him or her. If the court finds substantial evidence raises a
    doubt as to the minor‟s competency, the proceedings shall be suspended.
    “(b) Upon suspension of proceedings, the court shall order that the question of the
    minor‟s competence be determined at a hearing. The court shall appoint an expert
    to evaluate whether the minor suffers from a mental disorder, developmental
    disability, developmental immaturity, or other condition and, if so, whether the
    condition or conditions impair the minor‟s competency. The expert shall have
    expertise in child and adolescent development, and training in the forensic
    evaluation of juveniles, and shall be familiar with competency standards and
    accepted criteria used in evaluating competence. The Judicial Council shall
    develop and adopt rules for the implementation of these requirements.
    “(c) If the minor is found to be incompetent by a preponderance of the evidence,
    all proceedings shall remain suspended for a period of time that is no longer than
    reasonably necessary to determine whether there is a substantial probability that
    the minor will attain competency in the foreseeable future, or the court no longer
    retains jurisdiction. During this time, the court may make orders that it deems
    appropriate for services, subject to subdivision (h), that may assist the minor in
    attaining competency. Further, the court may rule on motions that do not require
    the participation of the minor in the preparation of the motions. These motions
    include, but are not limited to, the following:
    “(1) Motions to dismiss.
    “(2) Motions by the defense regarding a change in the placement of the minor.
    “(3) Detention hearings.
    “(4) Demurrers.
    “(d) If the minor is found to be competent, the court may proceed commensurate
    with the court‟s jurisdiction.

    3. Statutory construction of section 709
    In construing the statute, “we are guided by the overarching principle that
    our task „ “is to determine the intent of the enacting body so that the law may
    receive the interpretation that best effectuates that intent. [Citation.]” ‟ ” (Los
    Angeles Unified School Dist. v. Garcia (2013) 
    58 Cal. 4th 175
    , 186.) Our analysis
    begins with the language of the statute, which “ „generally is the most reliable
    indicator of legislative intent.‟ ” (People v. Cornett (2012) 
    53 Cal. 4th 1261
    ,
    1265.) “ „ “ „When the language of a statute is clear, we need go no further.‟
    [Citation.] But where a statute‟s terms are unclear or ambiguous, we may „look to
    a variety of extrinsic aids, including the ostensible objects to be achieved, the evils
    to be remedied, the legislative history, public policy, . . . and the statutory scheme
    of which the statute is a part.‟ ” [Citation.]‟ [Citation.]” (People v. Scott (2014)
    
    58 Cal. 4th 1415
    , 1421; accord, Lopez v. Superior Court (2010) 
    50 Cal. 4th 1055
    ,
    1063.)
    Minor argues that section 709 does not place the burden of proving
    incompetence on either party. As he points out, section 709, unlike Penal Code
    section 1369, subdivision (f), does not expressly provide for a presumption of
    competency. The Attorney General, for her part, maintains that section 709
    contains an implied presumption of competency and allocates the burden of
    rebutting that presumption to the party seeking a determination of incompetency.
    We agree with the Attorney General that the most straightforward reading
    of the text of section 709 is that minor is presumed competent. Competency
    procedures are triggered and proceedings are suspended when “the court finds
    (footnote continued from previous page)
    “(e) This section applies to a minor who is alleged to come within the jurisdiction
    of the court pursuant to Section 601 or 602.”
    12
    substantial evidence raises a doubt as to the minor‟s competency . . . .” (§ 709,
    subd. (a).) If no doubt is raised, or there is no substantial evidence to support such
    a doubt, the minor is treated as competent and subject to adjudication of the
    wardship petition, and the proceedings simply run their course. Were a minor not
    presumed competent, the statute arguably would require an affirmative showing of
    competency to proceed. The statutory text also suggests that the party asserting
    the minor‟s incompetency bears the burden of proof. Section 709, subdivision (c),
    requires the continued suspension of proceedings on a finding of incompetency by
    a preponderance of the evidence. By contrast, subdivision (d) provides for the
    reinstatement of proceedings “if the minor is found to be competent,” but does not
    refer to any standard of proof.
    We acknowledge that section 709‟s silence regarding any presumption of
    competency and allocation of the burden of proof permits other possible
    interpretations of the statutory text. We find, however, that our understanding of
    section 709 to include an implied presumption of competency is supported by the
    provision‟s legislative history and statutory purpose. (See City of Brentwood v.
    Central Valley Regional Water Quality Control Bd. (2004) 
    123 Cal. App. 4th 714
    ,
    722-727 [examining extrinsic aids to determine which party bore the burden of
    proving the applicability of exceptions to a mandatory minimum penalty for
    violating provisions of a waste water permit when the governing statute was silent
    as to which party bore the burden of proof].)
    a. Legislative history
    The materials considered by lawmakers in connection with the enactment
    of section 709, like the language of the statute itself, do not expressly refer to a
    presumption of competency or any allocation of the burden of proof. These
    materials demonstrate that in enacting section 709, the Legislature intended to
    13
    more effectively safeguard a juvenile‟s due process right not to be subject to
    adjudication while incompetent. Toward that end, the statute parts company with
    the adult competency scheme in certain specified ways that tailor the juvenile
    competency procedures to better fit the significant developmental differences
    between adults and juveniles and the distinctions between the adult and juvenile
    criminal justice systems.
    At the same time, however, and most significantly, we discern nothing in
    the legislative materials from which to infer that lawmakers intended to alter
    juvenile courts‟ existing practice of relying on the adult competency provisions in
    other respects. Specifically, nothing in the legislative history suggests lawmakers
    intended that Penal Code section 1369‟s presumption of competency for an adult
    criminal defendant should not apply to a minor facing adjudication as a ward of
    the juvenile court under section 601 or 602.
    Various legislative materials explained to lawmakers that existing
    procedures for determining competency in juvenile proceedings derived from the
    adult competency scheme, the Rules of Court, and judicial decisions. According
    to the legislation‟s author, whose statement was included in a number of bill
    analyses, the overarching problem with the lack of any statutory authority
    governing the juvenile court procedures was that this absence created uncertainty
    and inconsistent application of the developing case law. (See, e.g., Sen.
    Republican Floor Commentaries Assem. Bill No. 2212 (2009-2010 Reg. Sess.) as
    amended Aug. 5, 2010, p. 1365; Assem. Com. on Appropriations, Analysis of
    Assem. Bill No. 2212 (2009-2010 Reg. Sess.) as amended Apr. 22, 2010, p. 2;
    Assem. Com. on Public Safety, Analysis of Assem. Bill No. 2212 (2009-2010
    Reg. Sess.) as amended Apr. 8, 2010, p. 3 (Assembly Com. on Public Safety
    Analysis).) But the specific concerns regarding the application of adult
    competency procedures in juvenile courts were limited to two primary issues for
    14
    which there existed no corresponding provisions in the adult competency scheme,
    namely (1) developmental immaturity as an additional basis for incompetency, and
    (2) the need for the appointment of experts who are specially trained in the area of
    juvenile development to accurately evaluate the minor. “ „While case law
    suggest[s] that courts may rely on adult competency provisions in the absence of a
    juvenile statute on competency to stand trial, adult competency statutes do not
    address the nuanced application of “developmental immaturity” outlined in case
    law relevant to determination of competency in juveniles. . . . . [¶] Moreover,
    evaluation of children requires a professional expertise on child development, use
    of assessment instruments unique to evaluation of children in order to identify a
    mental disorder or developmental disability.‟ ” (Assem. Com. on 
    Appropriations, supra
    , at p. 2.) There is no suggestion that the presumption of competency itself
    was seen as a problem.
    Analyses of the bill prepared for various legislative committees echoed the
    author‟s concerns regarding certain specific gaps in the adult competency
    procedures, as applied to juvenile competency proceedings. The analyses also
    presented the arguments of the bill‟s institutional supporters, who likewise
    emphasized the increased understanding of how juveniles “ „think, perceive
    situations, and process information.‟ ” (Assem. Com. on Public Safety 
    Analysis, supra
    , at p. 9 [quoting an argument by Sacramento County Office of Public
    Defender].) The interested stakeholders whose statements in support of the
    proposed legislation were conveyed to lawmakers urged them to enact the bill, in
    part, to help ensure the constitutional rights of minors accused of crimes. The bill
    would protect a minor‟s rights, they argued, by (1) adopting the Dusky standard as
    the definition of juvenile competency, (2) codifying the holding of Timothy 
    J., supra
    , 
    150 Cal. App. 4th 847
    , that incompetency could be based on a juvenile‟s
    developmental immaturity, and (3) requiring that competency evaluations be
    15
    conducted by experienced, trained experts in the field of child development.
    (Assem. Com. on Public Safety 
    Analysis, supra
    , at pp. 8-11.) Notably, however,
    nothing in the stakeholders‟ statements or in the bill analyses themselves
    suggested that prior judicial reliance on the adult scheme should be rejected in any
    other respect. Nor was there any expression of concern that the adult competency
    scheme‟s presumption of competency and associated burden of proof would fail to
    adequately protect a minor from being adjudicated while incompetent.
    Minor points out that the legislative materials made clear there was no
    preexisting statutory authority for resolving doubts regarding competency in a
    juvenile proceeding. From this he argues that the Legislature would not have
    viewed the adult competency scheme as existing authority for juvenile
    competency determinations and, therefore, did not intend that the provisions from
    the adult scheme would apply in juvenile proceedings unless specifically so
    identified as being appropriate for minors. Minor‟s argument is refuted by the
    legislative materials themselves, which informed lawmakers that, under existing
    practice, juvenile competency proceedings were governed by a combination of the
    adult competency statutes, court rules, and judicial decisions. Contrary to minor‟s
    assertion, nothing in the history of section 709‟s enactment suggests that
    lawmakers considered the proposed legislation to comprise the sole and complete
    authority for juvenile competency determinations, or a wholesale rejection of
    procedures derived from the adult competency scheme.
    Minor argues furthermore that a presumption of competency for juveniles
    ignores the research on adolescent brain development, research that includes
    studies showing that many youth lack the capacity to adequately understand the
    legal process and assist their attorneys in defending their case. Minor‟s assertion
    is essentially a policy argument; indeed, the legislative history described above
    demonstrates that lawmakers considering whether to enact section 709 were amply
    16
    informed about the recent advances in understanding a minor‟s cognitive,
    psychological, social and moral development. Such information prompted the
    Legislature to add developmental immaturity as a basis for finding incompetency
    and to require that competency evaluations be conducted by experts skilled in
    child development. It is not inconsistent with the Legislature‟s interest in research
    on brain development that lawmakers neither eliminated statutory language
    suggesting that competency would be presumed nor specifically rejected Penal
    Code section 1369‟s presumption of competency in wardship proceedings.
    Rather, it reflects only that the Legislature was seeking to address the concerns
    raised by that research in ways other than evidentiary presumptions and their
    associated burdens of proof.
    Our review of the legislative history of section 709 suggests lawmakers did
    not intend to preclude juvenile courts from continuing to apply a presumption of
    competency to minors subject to wardship proceedings. Our task is not to
    consider whether it is preferable to presume a minor incompetent, subject to proof
    by a preponderance of the evidence that he or she is competent to proceed, but
    rather to discern what the Legislature intended in this regard. We conclude that
    the Legislature did not intend the enactment of section 709 to alter the existing
    practice of presuming a minor competent to undergo a wardship proceeding and
    imposing on the party claiming otherwise the burden of proving incompetency by
    a preponderance of the evidence.
    b. Policy
    The parties devote a sizable amount of their briefing to the policy
    considerations supporting their respective positions regarding the burden of proof
    that applies under section 709. The Attorney General argues, for example, that
    imposition of the burden of proof on a minor who claims incompetency comports
    17
    with policy concerns because, like an adult criminal defendant, the minor and
    minor‟s counsel have superior access to information relevant to competency. (See
    People v. 
    Medina, supra
    , 51 Cal.3d at p. 885 [concluding that Pen. Code, § 1369,
    subd. (f), does not offend due process by imposing on defendant the burden of
    proving incompetency, in part, because defendant and defense counsel likely have
    better access to the relevant information].) Minor counters that once the juvenile
    court finds substantial evidence raising a doubt regarding the minor‟s competency
    and appoints an expert to evaluate the minor, the expert has the best access to the
    relevant information, which supports allocating the burden of proof to neither
    party. Minor and amicus curiae on his behalf argue, alternatively, that imposing
    on the prosecution the burden of proving competency by a preponderance of the
    evidence advances “the unique and important role that the juvenile justice system
    has in rehabilitating juveniles” and the policy of protecting the vulnerability of
    children, especially those regarding whom a court has found substantial evidence
    raising a doubt as to competency.
    We need not resolve the debate regarding the policies supporting allocation
    of the burden of proof to one party or the other. Because we have concluded that
    section 709 did not effect a departure from the juvenile courts‟ application of the
    adult competency scheme‟s presumption of competency to minors in wardship
    proceedings, the policy arguments have been resolved by the Legislature. It
    necessarily follows from the presumption of competency that the burden of
    proving incompetency is borne by the party asserting it. As previously mentioned,
    although the adult competency scheme establishes a presumption of competency,
    it does not expressly allocate to any party the burden of proof at the competency
    hearing. We explained in People v. 
    Rells, supra
    , 
    22 Cal. 4th 860
    , that that statutory
    scheme‟s silence on this point is simply a function of the presumption of
    competency, which, in accordance with Evidence Code section 606, “operates to
    18
    impose the burden of proof on the party, if any, who claims that the defendant is
    mentally incompetent.” (
    Rells, supra
    , at p. 867.) A presumption affecting the
    burden of proof is one that has been “established to implement some public policy
    other than to facilitate the determination of the particular action in which the
    presumption is applied . . . .” (Evid. Code, § 605.) It is well settled that the
    presumption of competency comes within the category of policy-based evidentiary
    presumptions affecting the burden of proof. (
    Rells, supra
    , at p. 868.) Because the
    presumption of competency applies in a wardship proceeding, the party asserting
    incompetency bears the burden of proving the minor is incompetent to proceed.
    Amicus curiae for minor, the Office of the Public Defender, Sacramento
    County (Public Defender) argues that maintaining a presumption of competency,
    once there has been a prima facie showing that the minor is incompetent, is
    inconsistent with California‟s policy of presuming that a minor under the age of 14
    years is incapable of committing a crime. Under Penal Code section 26, paragraph
    One, before a minor under the age of 14 years may be adjudged a ward of the
    juvenile court, the prosecution must prove by clear and convincing evidence that
    the minor “appreciated the wrongfulness of the charged conduct at the time it was
    committed.” (In re Manuel L. (1994) 
    7 Cal. 4th 229
    , 232; accord, People v.
    Cottone (2013) 
    57 Cal. 4th 269
    , 280.)
    We reject the Public Defender‟s argument for several reasons. First,
    although some of the same considerations may be relevant to both the question of
    competency to stand trial and the question of capacity to commit crime, these
    inquiries differ in their purpose and scope. (Timothy 
    J., supra
    , 150 Cal.App.4th at
    p. 862.)
    We observe, moreover, that any possible interplay between the presumption
    of competency and the presumption of incapacity is limited to cases involving
    minors under the age of 14 years. In such cases, the presumption of competency
    19
    arises only if the minor is subject to adjudication under the juvenile law, that is,
    only after the prosecution has overcome the presumption of incapacity with clear
    and convincing proof that the minor knew the wrongfulness of his or her conduct.
    The presumption of competency presents no inconsistency with a presumption of
    incapacity that has been rebutted.
    B. Standard of review
    The other principal issue we address in this case concerns the standard by
    which an appellate court reviews a challenge to the sufficiency of the evidence
    supporting the juvenile court‟s determination in a competency proceeding under
    section 709. Minor argues for de novo review on appeal. The Attorney General
    maintains that the deferential substantial evidence review is appropriate here. As
    we explain, we agree with the Attorney General that the standard of review
    applicable in this case is the deferential substantial evidence test.
    1. Governing standard
    Decisions by this court have pointed to a verdict in a competency
    proceeding as an example of the type of “mixed question[] of law and fact” to
    which a deferential standard of review is applied. (People v. Holmes (2004)
    
    32 Cal. 4th 432
    , 442; see People v. Cromer (2001) 
    24 Cal. 4th 889
    , 895, 900.) In so
    doing, we have drawn on the reasoning of Thompson v. Keohane (1995) 
    516 U.S. 99
    , 113-114, which also pointed to such a determination as an example of a
    primarily fact-dependent issue that warrants deference in federal habeas corpus
    proceedings. (See 28 U.S.C. § 2254(d).) These precedents describe several
    factors that help distinguish lower court rulings that are reviewed deferentially
    from those that require independent review by the appellate court. First,
    deferential review is appropriate when the lower court‟s determination, as with a
    ruling on competency, is based upon its “ „first-person vantage‟ ” and, “to a
    20
    significant extent, on „ “first-hand observations made in open court,” ‟ which that
    court itself is best positioned to interpret.” (People v. Ault (2004) 
    33 Cal. 4th 1250
    ,
    1267; see People v. 
    Cromer, supra
    , at p. 901; Thompson v. 
    Keohane, supra
    , at
    p. 114.) Deferential review of a lower court‟s ruling such as the determination of
    competency is proper, moreover, because such a determination is an “individual-
    specific decision” that is “unlikely to have precedential value.” (Thompson v.
    
    Keohane, supra
    , at p. 114.) When a legal rule “acquire[s] content only through
    application,” independent review is indicated, as deference to the trial court‟s
    conclusions prevents the appellate court from carrying out its role to “maintain
    control of, and to clarify, the legal principles.” (Ornelas v. United States (1996)
    
    517 U.S. 690
    , 697; see People v. 
    Cromer, supra
    , at p. 896.) Deference is
    appropriate, however, when the lower court‟s determination is “highly
    individualized” (
    Cromer, supra
    , at p. 901) and would not likely result in an
    appellate opinion elucidating rules of general applicability. (See Thompson v.
    
    Koehane, supra
    , at p. 114, fn. 14.)
    We conclude that the deferential standard of review that applies to an adult
    criminal defendant‟s challenge to the sufficiency of the evidence supporting a
    verdict in a competency determination (People v. Samuel (1981) 
    29 Cal. 3d 489
    ,
    505; People v. Marshall (1997) 
    15 Cal. 4th 1
    , 31; People v. Frye (1998) 
    18 Cal. 4th 894
    , 1004), likewise applies to a minor‟s challenge to the sufficiency of the
    evidence supporting a juvenile court‟s determination regarding competency under
    section 709. Like the trier of fact in an adult competency trial, the juvenile court
    often makes its determination by conducting an evidentiary hearing, observing
    first hand not only the testifying witnesses but also the minor‟s behavior and
    interactions with counsel.
    Amici curiae on minor‟s behalf, Youth Law Center and Pacific Juvenile
    Defender Center, argue in favor of de novo review. They assert that, unlike in
    21
    adult court, where a jury may be called upon to weigh witness testimony, the
    juvenile courts decide the question of competency primarily on the documentary
    record of the minor‟s impairment and the expert‟s report, which renders
    deferential review unnecessary. Amici curiae provide no affirmative support,
    however, for their assertion that determinations in juvenile competency
    proceedings generally do not involve live testimony, and the case law seems to
    suggest otherwise. (See, e.g., In re Alejandro G. (2012) 
    205 Cal. App. 4th 472
    , 476
    [both of the appointed experts who evaluated the minor prepared reports and
    testified at the hearing]; In re Christopher F. (2011) 
    194 Cal. App. 4th 462
    , 466
    [the expert repeated in court his conclusion that the minor was not competent to
    proceed].) In any event, a juvenile court‟s determination regarding competency,
    even if made in the absence of an evidentiary hearing, may be informed by the
    court‟s own observations of the minor‟s conduct in the courtroom generally, a
    vantage point deserving of deference on appeal.
    A juvenile court‟s determination regarding competency also is like a verdict
    in a competency proceeding involving an adult criminal defendant in that both
    involve an “individual-specific decision” that is “unlikely to have precedential
    value.” (Thompson v. 
    Keohane, supra
    , 516 U.S. at p. 114.) Guided by the same
    well-settled legal definition of competency, both the juvenile court and the trial
    court draw their conclusions based on an appraisal of the particular expert
    testimony by mental health professionals, courtroom observations, and other
    testimonial and documentary evidence then before the court in the case. Neither
    determination involves the type of legal rule that acquires “ „ “meaning only
    through its application to the particular circumstances of a case,” ‟ ” such as the
    Fourth Amendment‟s doctrines of probable cause and reasonable suspicion, for
    which independent appellate review, rather than deferential review, is appropriate.
    (People v. 
    Cromer, supra
    , 24 Cal.4th at p. 896.)
    22
    Minor contends that independent review is nonetheless required for a
    juvenile court‟s determination regarding competency because of the importance of
    the constitutional right at stake and the consequences of an error by the juvenile
    court. As minor points out, a juvenile court‟s erroneous determination that the
    juvenile is competent could subject the juvenile to an adjudication while
    incompetent in violation of his or her due process right. The same constitutional
    considerations apply in adult proceedings, however, yet on appeal the deferential
    substantial evidence standard of review applies.
    2. Nature of the substantial evidence test for reviewing juvenile court
    determinations under section 709
    We have concluded that an appellate court applies a deferential standard
    when reviewing a claim that the record does not support the juvenile court‟s
    determination in a competency proceeding. Some features of the so-called
    substantial evidence test will apply to all such challenges on appeal. For example,
    the appellate court evaluating a claim of insufficient evidence supporting a
    determination of competency defers to the juvenile court and therefore views the
    record in the light most favorable to the juvenile court‟s determination. (See
    People v. 
    Samuel, supra
    , 29 Cal.3d at p. 505; People v. 
    Marshall, supra
    , 15
    Cal.4th at p. 31; People v. 
    Frye, supra
    , 18 Cal.4th at p. 1004.)
    There is, however, no single formulation of the substantial evidence test for
    all its applications. We observe that in the present matter, the evidence before the
    court consisted of Dr. Kojian‟s report and testimony, and the written materials on
    which he based his opinion that minor was not competent to stand trial. The
    prosecutor did not present any affirmative evidence of competency. Nor was he
    obligated to do so. As we have explained, under section 709, minor is presumed
    competent and had the burden of proving incompetency by a preponderance of the
    evidence. Even if the prosecution presents no evidence of competency, a juvenile
    23
    court can properly determine that the minor is competent by reasonably rejecting
    the expert‟s opinion. This court has long observed that “ „[t]he chief value of an
    expert‟s testimony in this field, as in all other fields, rests upon the material from
    which his opinion is fashioned and the reasoning by which he progresses from his
    material to his conclusion.‟ ” (People v. 
    Samuel, supra
    , 29 Cal.3d at p. 498.) In a
    case such as this one, therefore, the inquiry on appeal is whether the weight and
    character of the evidence of incompetency was such that the juvenile court could
    not reasonably reject it. (See 
    Samuel, supra
    , at pp. 498-506 [examining the facts
    on which the defense experts relied and the reasoning by which they arrived at
    their opinions to conclude that the jury could not reasonably have rejected the
    defense evidence of incompetence].)
    This court has used such a formulation of the substantial evidence test in
    two closely analogous decisions. The defendant in People v. Drew (1978)
    
    22 Cal. 3d 333
    , had entered a plea of not guilty by reason of insanity, which he had
    the burden of proving by a preponderance of the evidence. At the sanity trial, both
    of the court-appointed psychiatrists concluded that the defendant was insane at the
    time of the crime, and the prosecution presented no evidence. (Id. at pp. 338-339,
    350-351.) In addressing the defendant‟s claim that the jury‟s verdict of sanity was
    not supported by substantial evidence, we explained that under the circumstances
    of that case, the question on appeal was “whether the evidence contrary to that
    finding is of such weight and character that the jury could not reasonably reject it.”
    (Id. at p. 351.) The record supported the jury‟s verdict, we concluded, because the
    jury reasonably could have found that the psychiatrists failed to “present sufficient
    material and reasoning to justify” their opinions. (Id. at p. 351.) We pointed out,
    for example, that although both experts had diagnosed the defendant as suffering
    from latent schizophrenia that was characterized by assaultive behavior, neither
    expert explained why this diagnosis would lead to the conclusion that the
    24
    defendant met the definition of insanity such that he did not understand that his
    assault on the police officer victim was wrong. (Id. at pp. 350-351.)
    A similar formulation of the substantial evidence test appears in People v.
    Coogler (1969) 
    71 Cal. 2d 153
    . The capital defendant in that case had presented a
    diminished capacity defense to a charge of first degree deliberate and premeditated
    murder. (See Pen. Code, former § 1127b.) At the guilt phase of trial, three mental
    health expert witnesses testified for the defense that the defendant suffered from a
    disassociation reaction brought on by mental illness at the time of the killings, and
    each expert expressed the opinion that the defendant could not have acted with
    premeditation and deliberation. 
    (Coogler, supra
    , at pp. 162-165.) The
    prosecution did not present any expert witnesses of its own. (Id. at pp. 166.) The
    jury convicted the defendant of first degree murder and ultimately returned a
    verdict of death. On automatic appeal, the defendant argued that in light of his
    experts‟ testimony, the trial court erred by instructing the jury on first degree
    deliberate and premeditated murder. Reviewing the evidence presented in the
    case, this court held to the contrary that substantial evidence supported the court‟s
    instruction. We explained that a jury properly could reject the experts‟
    conclusions because of the material on which the experts relied. (Id. at p. 166-
    167.) For example, we observed, a jury properly could reject the opinion of the
    psychiatrist who had relied upon the defendant‟s own description of previous
    behaviors and limited recollection of the crimes, but had failed to consider the
    police reports or preliminary hearing transcripts. (Id. at pp. 162, 167.)
    The Court of Appeal in the present matter applied a substantial evidence
    standard when reviewing the juvenile court‟s competency determination. It erred,
    however, when describing the contours of that standard. Quoting verbatim from
    the decision in In re Christopher 
    F., supra
    , 194 Cal.App.4th at page 471, footnote
    6, the Court of Appeal characterized the applicable standard as a review of “ „ “the
    25
    whole record to determine whether any rational trier of fact could have found the
    essential elements of the crime . . . beyond a reasonable doubt,” ‟ ” stating further
    that “ „ “the record must disclose substantial evidence to support the verdict . . .
    such that a reasonable trier of fact could find the defendant guilty beyond a
    reasonable doubt.” ‟ ”4
    It is evident from both the language of the above quoted standard, and the
    decision from which that language was drawn, that the Courts of Appeal in In re
    Christopher F. and the present matter were reciting the standard for reviewing a
    challenge to the sufficiency of the evidence supporting a verdict of guilt. (See In
    re Christopher 
    F., supra
    , 194 Cal.App.4th at p. 471, fn. 6, quoting verbatim from
    People v. Zamudio (2008) 
    43 Cal. 4th 327
    , 357, which applied the quoted standard
    to the appellant‟s challenge to the sufficiency of the evidence supporting his
    robbery conviction.) A standard of review that inquires whether the record
    showed substantial evidence from which “a reasonable trier of fact could find the
    defendant guilty beyond a reasonable doubt” has no application in a challenge to
    the sufficiency of the evidence supporting a finding of competency, for either a
    juvenile or an adult criminal defendant. A competency determination does not
    4      The Court of Appeal stated as follows: “We review a juvenile court‟s
    finding of competence for substantial evidence. „The same standard governs our
    review of the sufficiency of evidence in juvenile cases as in adult criminal cases.
    “[W]e review the whole record to determine whether any rational trier of fact
    could have found the essential elements of the crime . . . beyond a reasonable
    doubt. [Citation.] The record must disclose substantial evidence to support the
    verdict — i.e., evidence that is reasonable, credible, and of solid value — such that
    a reasonable trier of fact could find the defendant guilty beyond a reasonable
    doubt. [Citation.] In applying this test, we review the evidence in the light most
    favorable to the prosecution and presume in support of the judgment the existence
    of every fact the jury could reasonably have deduced from the evidence.” ‟ ([In
    re] Christopher 
    F., supra
    , 194 Cal.App.4th at p. 471, fn. 6.)”
    26
    constitute a finding that the allegations in a wardship petition are true, or that a
    defendant is guilty of a crime. (Centeno v. Superior Court (2004) 
    117 Cal. App. 4th 30
    , 43 [“competency proceedings are civil in nature and collateral to
    the determination of defendant‟s guilt and punishment”].) Nor does a competency
    determination involve proof beyond a reasonable doubt. (§ 709, subd. (c)
    [incompetence is proved by a preponderance of the evidence]; Pen. Code, § 1369,
    subd. (f) [same].) As explained above, the proper formulation of the substantial
    evidence test for reviewing a challenge to the sufficiency of the evidence
    supporting a juvenile court‟s competency determination in a case such as this one,
    in which the evidence before the court consists of the opinion of a qualified expert
    concluding that the minor is incompetent to proceed and the materials on which
    the expert relied, inquires whether the weight and character of the evidence of
    incompetency was such that the juvenile court could not reasonably reject it.5
    C. Application of the standard of review
    Under section 709, a minor is incompetent to proceed in a wardship
    adjudication “if he or she lacks sufficient present ability to consult with counsel
    and assist in preparing his or her defense with a reasonable degree of rational

    and the materials on which the expert relied — reviews the court‟s determination
    deferentially, evaluating the record in the light most favorable to the court‟s
    determination and upholding it if the appellate court concludes that the court could
    reasonably reject the evidence of incompetency. Applying that standard here, we
    conclude that the court could not reasonably have rejected Dr. Kojian‟s
    compelling, well-supported, and unequivocal opinion that minor was not
    competent to proceed to trial.
    1. Evidence before the juvenile court
    a. The expert’s written report
    As previously mentioned, the court appointed forensic psychologist Haig J.
    Kojian, Ph.D., to evaluate minor‟s competency to stand trial. (See § 709,
    subd. (b).) In preparing his report, Dr. Kojian conducted a clinical interview with
    minor and spoke with minor‟s mother by telephone. He also reviewed minor‟s
    school records and the responding officers‟ detention reports in the present matter.
    Based on these sources, Dr. Kojian concluded that minor was not presently
    competent to stand trial.
    Dr. Kojian‟s report first discusses the results of his mental status
    examination of minor. According to the report, minor‟s presentation appeared
    impaired and there was evidence of an altered thought process. Minor‟s speech
    and movements were slow and deliberate, and his gait was rigid. Moreover, his
    affect appeared incongruent with thought content. For example, he smiled for no
    reason and out of context. Dr. Kojian noted that minor stated several times that he
    was confused and repeatedly changed his responses to questions. He also told
    Dr. Kojian that he was depressed.
    When Dr. Kojian indicated that he would like to administer some
    psychological tests, minor refused, saying, “I just don‟t feel I need to do this.”
    28
    Dr. Kojian ultimately managed to assess minor with an abbreviated version of the
    “Rey 15-Item Test” for ruling out malingering, to which minor responded
    appropriately.
    Dr. Kojian reported that minor was unable to provide any meaningful self-
    history. For example, although minor correctly reported he was living with his
    mother, stepfather, and stepsibling at the time he was detained, he also said that he
    had a good relationship with his parents. Minor denied using alcohol or drugs,
    which Dr. Kojian found unconvincing. He also denied being in special education
    classes, which contradicted school records. Although minor reported having been
    suspended from school once or twice, he could not remember why.
    At various points during the evaluation, minor told Dr. Kojian that he was
    “confused right now.” Dr. Kojian reported that, when asked to elaborate, minor
    “wasn‟t making much sense.” Specifically, minor indicated that his mother was
    confusing him and that he “didn‟t know her or her side of the story.” Minor also
    stated, “Hard times . . . problems.” When asked to explain, minor indicated he had
    difficulty with talking, saying, “Just the language . . . in school though” and “little
    problem.”
    Dr. Kojian‟s telephone interview with minor‟s mother disclosed that
    although minor had met developmental milestones on a timely basis, he had been
    diagnosed with “mental problems.”
    Dr. Kojian devoted most of his report to the issues relevant to a finding of
    competency, specifically, whether minor is capable of consulting with counsel,
    assisting in his defense, and understanding the nature of the charges and the
    proceedings. (See § 709, subd. (a).) Minor‟s responses to Dr. Kojian‟s questions
    suggested to him that minor “was confused and didn‟t know what was going on.”
    Some of minor‟s confusion concerned the reason for his detention.
    Specifically, when minor was asked why he was in custody he first stated it was
    29
    for “being on the porch,” an apparent reference to his being returned to juvenile
    detention for violating the terms of his home supervision program (HSP) release.
    (Minor was aware that he had been detained for several weeks, had been released
    on HSP, and was then returned to custody.) When Dr. Kojian clarified that he was
    asking about the original detention, minor indicated he was in custody for “not
    understanding,” “for being confused,” and “for his safety.” In response to
    Dr. Kojian‟s suggestion that these were not crimes, minor said, “Disturbing the
    peace.”
    Minor then offered another reason for his being in custody, stating that he
    had been detained because “it was thought he was using drugs,” which he denied.
    When Dr. Kojian questioned minor further on the subject, minor indicated that a
    prior drug matter had been resolved “by me understanding it.” Minor correctly
    identified the earlier drug case as a misdemeanor, and stated that misdemeanors
    were less serious than felonies “such as disturbing the peace.”
    According to Dr. Kojian‟s report, minor correctly described some of the
    aspects of the legal proceedings against him but was confused about, or ignorant
    of, others. For example, minor knew that a misdemeanor is less serious than a
    felony, but he did not know the difference between a plea bargain and trial. Minor
    also expressed some confusion over whether or not he had an attorney. He did not
    know counsel‟s name and did not understand counsel‟s duty and function. Nor
    was he aware of the prosecutor‟s function. Minor did know that the judge “makes
    the decisions,” but he did not know what types of decisions those were. He also
    understood being guilty meant he was “responsible,” but he believed that the
    determination of guilt depended on “whether he attends school.”
    When Dr. Kojian returned to the subject of the specific charges in the case,
    minor first indicated he was being charged with disturbing the peace, a crime
    different from those alleged in the wardship petition. In response to Dr. Kojian‟s
    30
    suggestion that that was not the charge, minor said, “messing up my house,”
    “playing with mom and dad,” “for not being serious,” and “for not going to
    school.” Dr. Kojian hinted to minor that the charges involved a knife, prompting
    minor to offer various guesses, including “Me risking myself and not being
    serious?,” “Me messing up?,” and “For me being confused?”
    As previously mentioned, Dr. Kojian‟s assessment of minor‟s competency
    included information gleaned from the detention reports and minor‟s school
    records. He noted specifically minor‟s mother‟s statement to responding officers
    that minor recently had stopped taking his medication and that “with each episode
    he gets worse.” He found significant a notation by one of the officers that minor
    seemed to be having trouble understanding the questions posed to him and
    appeared “confused.” Dr. Kojian also found useful information in what he
    referred to as minor‟s IEP (individualized education plan), for example, that minor
    had been receiving special education services due to a mood disorder. Written
    assessments by some of minor‟s teachers included comments such as “He acts like
    he is under the influence” and he “[does] not seem to know what is going on at all
    in school.”
    Based upon his observations and assessment of minor, his interview with
    minor‟s mother, and his review of the identified records and reports, Dr. Kojian
    concluded that minor was impaired and that two underlying issues were causing
    minor‟s impairment. Specifically, he found that minor was both “clearly suffering
    from depression” and that minor‟s thinking and cognitive functioning was “clearly
    disrupted.” Dr. Kojian acknowledged that because he did not administer any
    standardized tests to minor, he could not determine the etiology, or source, of the
    impaired cognitive functioning. He did not believe the impairment was
    developmental. Rather, he was of the view that minor either could be in the early
    stages of schizophrenia or other psychotic disease, or that he could be using more
    31
    drugs or different drugs than earlier reported, which has resulted in organic
    impairment.
    In concluding remarks, Dr. Kojian wrote that “it appears from all accounts”
    that minor was not competent to stand trial at the present time. He found that
    minor was “legitimately confused” about what is occurring and that “in his current
    condition does not have the capacity to meaningfully and rationally cooperate with
    counsel to prepare a defense or to assist counsel in a meaningful and rational
    manner.” In light of minor‟s confused and vacillating responses during the
    interview, Dr. Kojian also questioned whether he fully understood the nature of
    the proceedings against him. Dr. Kojian acknowledged that perhaps the charges
    against minor had been reduced to disturbing the peace. In his view, however,
    minor‟s statements, for example, his assertion that his drug case had been resolved
    “because he, now, understands,” suggest he is confused about the present charges
    and the proceedings.
    b. Expert’s testimony at the competency hearing
    Minor‟s counsel offered to submit the question of minor‟s competency
    solely on the basis of Dr. Kojian‟s report, without an evidentiary hearing. The
    prosecutor indicated, however, that because Dr. Kojian had not administered any
    tests to minor, he wanted to question him in this regard. The court granted the
    prosecutor‟s request and held a hearing in late April 2012, at which Dr. Kojian
    was the only witness called to testify. Before questioning commenced, the court
    granted minor‟s counsel‟s request to take judicial notice of two sets of documents
    in the case file, a probation modification petition and the officers‟ detention
    reports.
    32
    Dr. Kojian testified regarding his qualifications and the substance of his
    written report. He indicated that his forensic psychology practice spanned over
    20 years, during which time he had evaluated thousands of juveniles.
    Much of Dr. Kojian‟s testimony echoed his written report, and he
    confirmed that he “had no doubt” minor had an “impairment of some sort.”
    Regarding the sources of that impairment, he reiterated his observation that minor
    appeared to be depressed and his conclusion that minor‟s depression could be
    affecting his functioning. He noted in this regard that the medication minor had
    been prescribed, Abilify, is used to treat mood disorders. He also repeated his
    finding that minor‟s appearance, affect and vacillating responses to his questions,
    coupled with the statements by minor‟s teachers, parents, and the officers who
    detained him, suggested impaired cognitive functioning, and he reaffirmed his
    view that minor was “legitimately confused.” Dr. Kojian testified, consistently
    with his report, that minor‟s difficulty explaining what he was being charged with,
    his erroneous explanations as to why he was in custody, and one responding
    officer‟s observation that the minor appeared confused, led him to believe minor
    could not consult with counsel and did not fully understand what was happening.
    At the hearing, Dr. Kojian described in more detail the records that he had
    reviewed in reaching his opinion that minor was incompetent. Specifically, he had
    examined the wardship petition, the detention reports, a May 2011 child guidance
    letter from minor‟s therapist, Arthur Montes, a licensed clinical social worker, and
    a January 2011 psychoeducational report by a school psychologist at minor‟s high
    school. According to Dr. Kojian, the school records presented a consistent theme
    that minor is very slow, his testing is low, and that “something is wrong with
    him.”
    The prosecutor‟s questioning of Dr. Kojian focused mostly on whether
    minor‟s refusal to be tested affected Dr. Kojian‟s opinion that minor was
    33
    incompetent. Dr. Kojian indicated that administering tests would not have
    changed his opinion. He stated, “If I wasn‟t 100 percent sure of my opinion I
    wouldn‟t have written it in my report the way I wrote it and signed my name.”
    With regard to the issue of malingering, Dr. Kojian explained that a discrepancy
    between a minor‟s presentation and other information available to the evaluator,
    such as comments by parents and teachers, “raises a red flag that someone is
    „faking,‟ ” but that no such discrepancy existed here. Dr. Kojian also testified that,
    in his view, minor did not seem to be malingering. He indicated that he had given
    minor a brief, “malingering-type” test and that minor “didn‟t fire on any of those
    questions.”
    The prosecutor also questioned Dr. Kojian regarding the passage of time
    between completion of his report in mid-April 2012, and his testimony at the late
    April hearing, asking whether it was possible minor could have regained
    competency during that nine-day period of time. Dr. Kojian explained that
    competency is not a static condition, and that if it seemed that minor was
    improving, he might need to be reevaluated. He expressed the view, however, that
    no doctor can say how a subject is, on the particular day that the doctor testifies
    regarding an earlier assessment. When pressed by the prosecutor whether his
    opinion is that minor, as he was then sitting in the courtroom, was incompetent to
    stand trial, Dr. Kojian indicated that on the day he signed his report he was of the
    opinion that minor was incompetent but that he did not know what minor‟s
    functioning was on the day of the hearing.
    During closing argument by the parties, defense counsel recalled that the
    court had had to read the delinquency petition to minor “word by word.” For his
    part, the prosecutor emphasized his concerns regarding Dr. Kojian‟s failure to
    administer any tests to minor and suggested the court appoint a second expert to
    evaluate him.
    34
    c. Documentary evidence
    After hearing Dr. Kojian‟s testimony and closing argument by the parties,
    but before announcing its ruling, the court called a recess in order to review
    Dr. Kojian‟s written report and the two documents in the case file that it had
    agreed to judicially notice. One of the documents in the file was a February 2012
    probation modification petition recommending the termination of wardship
    jurisdiction over minor that stemmed from an incident in 2010. The modification
    petition included several attachments, one of which was a March 2011
    psychoeducational report by the school psychologist at minor‟s high school that
    was prepared in connection with a “manifestation determination,” which
    Dr. Kojian had relied upon in forming his opinion. That report is summarized
    below.
    The purpose of a manifestation determination is to decide whether the
    misbehavior of a special education student with an IEP is related to his or her
    disability. If it is determined that the student‟s violation of school rules is a
    manifestation of the disability, the student is entitled under state and federal law to
    special disciplinary rules for students with disabilities. (See Ed. Code, § 48915.5;
    20 U.S.C. § 1415(k).) The psychoeducational report at issue here indicated that
    minor had been a special education student since 2006 and was then receiving
    services in the “mild to moderate” program.
    The report covered a number of topics, including minor‟s medical and
    educational history, observations by minor‟s teachers, the results of various
    standardized assessments of minor conducted in January 2011, and an analysis of
    whether the assessment results or other information established that minor met the
    eligibility requirements for certain specified disabilities that would entitle minor to
    additional special education services.
    35
    With regard to minor‟s medical history, the report indicated that he had
    been diagnosed with a mood disorder for which he was being treated by Arthur
    Montes. The report concluded that minor met the special education eligibility
    criteria for disability under the category of “other health impairment” because his
    diagnosed mood disorder was adversely affecting his educational performance.
    The report‟s discussion of minor‟s educational history indicated he had
    excessive unexcused absences and had earned very few units toward graduation.
    It also showed a fairly lengthy disciplinary record, including an incident that
    occurred about seven weeks before the manifestation determination report, in
    which minor was found to be under the influence of marijuana and in possession
    of a Prozac pill. In connection with that incident, he was arrested for possessing a
    prescription drug without the prescription and released to his mother. The
    behavior that appears to have triggered the manifestation determination report
    occurred six weeks later, when minor was suspended for five days after receiving
    from another student a backpack containing two stolen cellular telephones.
    The report included questionnaire results and comments by many of
    minor‟s teachers. Several teachers indicated minor was quiet, inattentive, and
    unproductive. His “auto-tech” teacher remarked that at times minor showed some
    mechanical interest but “seems lost . . . most of the time.” Minor‟s English
    teacher reported that minor “acts like he is under the influence” and “does not
    seem to know what is going on at all in school.”
    In summarizing the standardized assessment results, the report indicated
    that although minor scored in the average range in visual processing of
    information, he fell within the “low” or “very low” range in numerous, if not most,
    other areas. His overall intellectual ability, for example, was very low, as was his
    comprehension, long-term retrieval, processing speed, and short-term memory.
    36
    Although the report indicated that minor met the special education
    eligibility criteria for disability under the category of “other health impairment,” it
    showed he did not meet eligibility criteria under any other category, including
    “special learning disability,” “speech and language impaired,” and “intellectually
    disabled.”
    The report ultimately found that the behavior at issue was a manifestation
    of minor‟s disability and concluded that his low cognitive and comprehension
    skills “can make it difficult for him to process the differences between right and
    wrong” and that “he can be easily influenced to do wrong.” The report indicated
    that its assessment would be reviewed by the IEP team and used to determine
    appropriate placement and services for minor.
    The second document attached to the probation modification petition was a
    May 2011 letter from minor‟s therapist, Arthur Montes. The purpose of Montes‟s
    letter was to request an “intake assessment” to determine if minor had a
    developmental disability. Referring to the manifestation determination‟s
    psychoeducational report as an “I.E.P.,” Montes pointed to its findings regarding
    minor‟s subaverage intellectual functioning and extremely low cognitive and
    comprehension skills as grounds justifying an intake assessment.
    2. The court’s ruling
    The court began its ruling by describing the evidence it had considered in
    making its determination. Specifically, the court indicated it had considered
    Dr. Kojian‟s testimony and written report, the detention reports, and the probation
    modification petition, which included the manifestation determination‟s
    psychoeducational report and the letter from therapist Arthur Montes. The court
    observed that it was not obligated to adopt Dr. Kojian‟s opinion that minor was
    37
    incompetent to proceed. It found instead that minor was competent and had failed
    to sustain his burden of showing otherwise by a preponderance of the evidence.
    The court took a short recess after announcing its ruling and then went back
    on the record to briefly explain the grounds on which it had reached its decision.
    With regard to the documentary evidence, the court indicated it had disregarded
    Montes‟s opinion that minor was developmentally delayed because that opinion
    was simply a “piggyback” of the manifestation determination report, which, the
    court observed, was not “a full determination of what was needed for the I.E.P.”
    The court noted that school personnel were “still going to be in the process of
    determining appropriate placement and services.”
    The court remarked that Dr. Kojian “appeared . . . to have extensive
    experience” but it nonetheless rejected his opinion that minor was unable to assist
    his counsel. The court explained that it reached that conclusion, in part, because
    Dr. Kojian “was not able to fully determine whether there was malingering and
    was unable to complete the [„Rey 15-Item Test‟].”
    The court also was unpersuaded by Dr. Kojian‟s conclusion that minor‟s
    statements during the interview indicated confusion. The court found to the
    contrary that minor‟s characterization of the charges against him were appropriate
    responses given that minor had been released on HSP but failed to comply with its
    conditions, and in light of what minor allegedly had done. In the court‟s view,
    “messing up my house and not going to school . . . at least was alleged to have
    been the genesis of what ended up in the charged offenses.” The court observed
    furthermore that minor knew that a misdemeanor was less serious than a felony
    and understood, correctly, that an earlier offense involving possession of drugs at
    school had been taken care of.
    The other reason cited by the court for rejecting Dr. Kojian‟s opinion was
    that the manifestation determination report had not “completely relied” on the
    38
    “I.E.P. testing” in reaching its conclusion. Specifically, the court found it
    significant that the report‟s author believed minor‟s “cognitive and adaptive delays
    may have been drug induced” and noted that testing carried out in 2009 did not
    indicate the same cognitive and adaptive delays shown by the more recent testing.
    3. The court could not reasonably reject the expert’s conclusion that
    minor was not competent to proceed
    We have concluded that an appellate court evaluating a challenge to the
    sufficiency of the evidence supporting a determination of competency under
    section 709 views the record in the light most favorable to the finding and, in a
    case like the present matter, asks whether the weight and character of the evidence
    of incompetency is such that the juvenile court could not reasonably reject it.
    Applying this formulation of the substantial evidence test here, we conclude that
    the court could not reasonably have rejected Dr. Kojian‟s opinion that minor was
    not competent to stand trial.
    The juvenile court could not reasonably call into question the material on
    which Dr. Kojian based his opinion that minor was not competent to proceed. The
    expert‟s evaluation of minor included an assessment of minor‟s appearance, affect
    and speech, and a comprehensive interview covering various aspects of minor‟s
    background, the reasons for minor‟s detention, and minor‟s understanding of his
    present situation. Dr. Kojian interviewed minor‟s mother regarding minor‟s
    mental health history, and reviewed statements by teachers and responding
    officers regarding minor‟s behavior in school and at the time of his arrest,
    respectively. He also examined school records, which included minor‟s
    disciplinary history, his grades, and the results of recent standardized testing for
    cognitive functioning, intellectual ability, and other skills. Nothing in the record
    suggested that Dr. Kojian‟s evaluation had overlooked a significant indicator of
    competency. And nothing indicates that his inquiry focused on something other
    39
    than the correct competency standard, namely, minor‟s present ability to assist
    counsel in preparing a defense and a rational understanding of the charges and
    proceedings.
    We observe furthermore that Dr. Kojian expressed little reservation
    regarding his opinion that minor was incompetent. The Attorney General points to
    certain testimony to suggest Dr. Kojian‟s opinion was tenuous. Read in context,
    however, Dr. Kojian‟s statement that he “believed to a reasonable degree of
    psychological certainty that [his] opinion was probably correct” and that “it
    appears . . . that this young man is not competent to stand trial at this time”
    demonstrated an attempt to express his opinion within professional parameters,
    and not to suggest any reservations in his views. (Cf. People v. 
    Marshall, supra
    ,
    15 Cal.4th at p. 32 [expert admitted his opinion that the defendant was
    incompetent “lacked „a level of reasonable medical certainty‟ ”].)
    One of the court‟s principal reasons for rejecting Dr. Kojian‟s opinion was
    that the expert had not “fully determine[d]” whether minor was malingering and
    “was unable to complete” the Rey 15-Item Test. On this record, however, the
    expert‟s inability to administer a standardized test for malingering did not
    undermine the reasoning by which he arrived at his opinion. Although the
    prosecutor questioned Dr. Kojian at length regarding his failure to administer the
    Rey 15-Item Test for malingering, Dr. Kojian concluded that minor was not
    malingering and stated he was “100 percent sure” of his opinion notwithstanding
    minor‟s refusal to be assessed with objective measures. As he explained, a
    discrepancy between a minor‟s presentation during the evaluation and other
    information available to the evaluator, such as comments by parents and teachers,
    could suggest the minor is faking his or her responses, but no such discrepancy
    existed in the present case. Dr. Kojian also indicated that he had given minor a
    brief malingering-type test and that minor “didn‟t fire” on any of the questions.
    40
    This court has long recognized that an expert is “entitled to base his opinion on
    observations of, and statements made by, the patient during a routine
    psychological interview.” (People v. Stoll (1989) 
    49 Cal. 3d 1136
    , 1155.) We
    observe that in assessing the strength of an expert‟s opinion, a juvenile court
    properly may take into account a minor‟s refusal to be tested with objective
    measures. On the record presented here, however, the court could not reasonably
    point to Dr. Kojian‟s inability to administer a complete standardized test for
    malingering as a reason on which to reject the expert‟s opinion that minor was not
    competent to stand trial.
    In rejecting Dr. Kojian‟s opinion, the court also pointed to certain
    statements by minor that, in the court‟s view, contradicted Dr. Kojian‟s conclusion
    that minor was confused. The identified responses were limited and incomplete,
    however, and did not provide a reasonable basis on which to reject the expert‟s
    opinion.
    Minor was aware generally that a misdemeanor was less serious than a
    felony, that a judge makes decisions, and that being guilty means he is
    “responsible.” The record also shows that when the arresting officer gave minor
    his Miranda advisements at the time of his arrest (Miranda v. Arizona (1966)
    
    384 U.S. 436
    ), minor invoked his right to silence. But most of minor‟s answers to
    Dr. Kojian‟s questions reflected ignorance of, or confusion regarding, many of the
    significant features of a juvenile adjudication. For example, minor could not
    describe the functions of defense counsel and the prosecutor, the differences
    between a plea bargain and a trial, and the types of decisions that are made by a
    juvenile court judge. Minor also was uncertain he was being represented by
    counsel and he believed the determination of his guilt depended on “whether he
    attends school.”
    41
    Admittedly, some of minor‟s curious answers as to why he was in custody
    were explainable. His initial answer that he was in custody for “being on my
    porch” was understandable in light of the fact he originally was allowed to live at
    home pending the competency hearing but was returned to juvenile detention
    10 days later for violating the conditions of his release pursuant to the Home
    Supervision Program, presumably by going outside the residence. And minor‟s
    statement that he was being charged with “messing up my house” and “not going
    to school” arguably was an accurate reflection of some of the factual
    underpinnings of the charges against him, as the court pointed out. But Dr.
    Kojian‟s report and testimony indicated that, from the outset, minor seemed to
    misunderstand what was meant by a criminal charge. During the interview, when
    told that “being confused” and “not understanding” were not crimes, minor said he
    was being charged with disturbing the peace. And when informed by Dr. Kojian
    that that crime was not the charge, minor again described the charges in vague,
    factual terms. Most significantly, as Dr. Kojian observed, minor exhibited no
    awareness of the most important facts underlying the charges, namely, that he
    allegedly had threatened family members with a knife. On this record, the court
    could not reasonably reject the expert‟s opinion on the basis of isolated statements
    suggesting minor understood some features of a juvenile proceeding generally, or
    on the ground that minor‟s confusion in some respects could be explained.
    Nor were any of the other grounds offered by the juvenile court a
    reasonable basis for rejecting the expert‟s opinion that minor was incompetent.
    The court found that evidence of a possible link between minor‟s drug use and his
    significant intellectual and adaptive deficits called into question Dr. Kojian‟s
    opinion. Specifically, the court emphasized the portion of the manifestation
    determination report indicating (1) that minor‟s significant cognitive and adaptive
    delays shown by the most recent testing “may have been drug induced” and
    42
    (2) that the results of earlier assessments showed minor‟s scores in those areas fell
    within average ranges. Our examination of the report, however, discloses that this
    cited evidence concerned the question of the minor‟s eligibility for special
    education services based on “intellectual disability,” a disability category formerly
    referred to as mental retardation. To qualify for special education services under
    that category it must be shown that the student‟s significant deficits in intellectual
    functioning and adaptive behavior “manifested during the developmental period.”
    (Cal. Code Regs., tit. 5, § 3030, subd. (b)(6); see Ed. Code, § 56026, subd. (a).)
    The school psychologist who authored the report expressed the view that minor‟s
    current, significant deficits in intellectual and adaptive functioning adversely
    affected his educational performance. But she concluded nonetheless that minor
    did not meet the eligibility criteria for intellectual disability because minor‟s
    deficits appeared to have been drug induced and, according to prior testing, had
    not arisen during the developmental period.
    This evidence was not inconsistent with, nor did it contradict, Dr. Kojian‟s
    opinion because his conclusions regarding the conditions causing minor‟s
    incompetence were not based on a finding of intellectual or developmental
    disability. Rather, Dr. Kojian‟s report to the court expressly stated that one of the
    causes of minor‟s incompetency, the impairment of his cognitive functioning, did
    not appear to be developmental in nature. And to the extent the evidence cited by
    the juvenile court was relevant to the question of minor‟s competency, it
    supported, rather than refuted, Dr. Kojian‟s opinion. Dr. Kojian had indicated that
    he found two underlying causes of minor‟s incompetency, a mood disorder and an
    impairment in minor‟s cognitive functioning. As to the latter condition,
    Dr. Kojian believed the impairment was attributable to one of two sources —
    either a serious, emerging mental disease such as schizophrenia, or extensive drug
    use that had led to organic deficits. That the manifestation determination report
    43
    attributed minor‟s recently assessed cognitive delays to his use of drugs further
    bolstered one of Dr. Kojian‟s theories regarding the etiology of minor‟s impaired
    thinking.
    None of the other reasons given by the court when explaining why it
    declined to accept Dr. Kojian‟s opinion were relevant to an assessment of the
    materials and reasoning used by Dr. Kojian in reaching his conclusion that minor
    was incompetent. For example, the court indicated it had rejected the belief by
    Montes, minor‟s therapist, that minor had a developmental delay because that
    opinion simply “piggyback[ed]” on the information provided in the manifestation
    determination report. But Dr. Kojian, consistent with the court‟s view of Montes‟s
    opinion, had expressed the opinion that minor‟s incompetency was caused, not by
    any developmental disability or delay, but rather by either a mood disorder or
    substantial impairments in his thought and cognitive functioning.
    One final reason for rejecting Dr. Kojian‟s opinion mentioned by the court
    was that the manifestation determination report was not a “full” IEP, and that
    appropriate placement and services for minor had yet to be determined. Even
    assuming that these points constitute a valid criticism of the material on which
    Dr. Kojian based his conclusions, the court could not reasonably have relied on
    them to reject the expert‟s opinion. The manifestation determination report stated
    that minor had been diagnosed with a mood disorder. This diagnosis, however,
    was consistent with similar information Dr. Kojian gleaned from other sources.
    For example, minor himself had indicated that he was depressed, and Dr. Kojian
    had learned from the initial detention report that minor was taking Abilify, which
    he knew is typically used for the treatment of mood disorders. Dr. Kojian‟s report
    also referenced the portion of the manifestation determination report in which
    minor‟s teachers remarked that he seemed confused and impaired. He did so,
    however, as further support for his own observations of minor‟s mental status and
    44
    apparent confusion during the in-person interview. Notably, Dr. Kojian did not
    rely on the manifestation determination report‟s summary of the 2011 standardized
    testing results, which showed significant intellectual and cognitive deficits, as a
    basis for concluding that minor‟s cognitive functioning was impaired. Instead,
    Dr. Kojian acknowledged that because of minor‟s refusal to be tested during the
    evaluation, he was unable to pinpoint the cause of that impairment. Given
    Dr. Kojian‟s minimal reliance on the manifestation determination report in
    reaching his conclusions, the court‟s stated concerns regarding the adequacy of
    that material did not justify the rejection of Dr. Kojian‟s opinion.
    In arguing that the court reasonably could reject the evidence of
    incompetency, the Attorney General points to Dr. Kojian‟s testimony “admitting”
    that his opinion, although accurate on the day he signed his report, might not
    reflect minor‟s mental state on the day of the hearing. We are not persuaded that
    this line of questioning undermined Dr. Kojian‟s opinion. An expert‟s written
    report necessarily precedes his or her testimony at the competency hearing. On
    this record, it is speculative that the time between the completion of the report and
    the date of the hearing renders the expert‟s opinion stale. Significantly, there was
    nothing in the record suggesting minor‟s mental status had improved in the nine
    days between the date of Dr. Kojian‟s report and the hearing. We note moreover
    that the court did not reference the cited testimony when explaining the reasons for
    rejecting Dr. Kojian‟s opinion.
    The court correctly observed that it was not obligated to accept an expert‟s
    opinion of incompetency. This court‟s decisions have long recognized the
    propriety of rejecting even unanimous expert opinion, such as when, for example,
    the experts were unfamiliar with the evidence that would tend to explain the
    defendant‟s behavior (People v. Marks (2003) 31 Cal.4th, 197, 219), when the
    experts‟ opinions were based solely on a brief interview with the defendant
    45
    (People v. 
    Marshall, supra
    , 15 Cal.4th at p. 32), and when the experts‟ opinions
    regarding the defendant‟s incompetency were tenuous. (Ibid.) Similarly, in In re
    Alejandro 
    G., supra
    , 
    205 Cal. App. 4th 472
    , 480-481, the Court of Appeal agreed
    with the juvenile court that the court was under no obligation to accept the experts‟
    opinions that the minor was incompetent. In that case, one of the experts found
    the minor “ „close to being competent‟ ” and “ „capable of understanding the
    proceedings,‟ ” while the other expert had evaluated the minor‟s understanding of
    the proceedings by asking him questions pertaining to procedures applicable to
    adult criminal trials, not juvenile adjudications. As previously discussed,
    however, neither Dr. Kojian‟s evaluation of minor nor his opinion suffered from
    similar infirmities.
    Amicus curiae National Center for Youth Law has argued that, because of
    the highly complex nature of juvenile competency proceedings, juvenile courts
    should defer to the opinion of the court-appointed expert unless there is a clear
    reason not to do so. We reject the proposition that a court should defer to the
    opinion of an expert. “ „To hold otherwise would be in effect to substitute a trial
    by “experts” for a trial by [the finder of fact] . . . .‟ [Citation.]” (People v.
    
    Samuel, supra
    , 29 Cal.3d at p. 498.) We recognize at the same time, however, that
    although an expert‟s opinion is not determinative of the question of competency,
    such an opinion holds special significance in the juvenile competency setting, as
    contemplated by the Legislature. (See In re John Z. (2014) 
    223 Cal. App. 4th 1046
    ,
    1058 [the reports and testimony of experts who have evaluated the minor for
    competency are clearly intended to play a central role in the competency
    determination under § 709].) Under section 709, the juvenile court must appoint
    an expert, specially qualified in the field of child development, when there is
    substantial evidence raising a doubt regarding the minor‟s competency. (§ 709,
    subds. (b), (c).) The statutory scheme therefore contemplates the court will make
    46
    its determination whether a minor is competent or incompetent with the expert‟s
    specialized knowledge and views in mind. On the record presented in this case,
    the court‟s rejection of the expert‟s opinion was made in the absence of
    disagreement among qualified experts. When, as here, the expert concludes that
    the minor is incompetent but the juvenile court finds flaws in the expert‟s
    methodology and reasoning, the court should consider appointing a second expert
    to inform the court‟s view that the first expert‟s opinion is inadequate. We
    observe that in the present case, when the prosecutor expressed concerns with the
    expert‟s failure to administer standardized tests, he suggested that the court
    appoint a second expert to evaluate minor.
    For the reasons discussed above, we conclude that on the record before us
    in this case, the juvenile court could not reasonably have rejected the expert‟s
    opinion that minor was not competent to proceed.
    47
    III. DISPOSITION
    Because the Court of Appeal found that the juvenile court‟s reasons for
    declining to accept the expert‟s opinion were supported by substantial evidence in
    the record and affirmed the judgment, the Court of Appeal‟s judgment is reversed.

    DISSENTING OPINION BY CHIN, J.
    I agree with the majority that, under Welfare and Institutions Code section
    709,1 a minor is presumed competent and bears the burden of proving otherwise
    by a preponderance of the evidence. However, under the deferential standard of
    appellate review that applies in light of this conclusion, I would affirm the juvenile
    court‟s finding that R.V. was competent. I therefore dissent.
    1. The Standard of Review.
    The standard of appellate review that applies here follows from (1) the
    majority‟s conclusion, with which I agree, that R.V. bore the burden of proving
    incompetency by a preponderance of the evidence, and (2) the juvenile court‟s
    finding that R.V. failed to sustain that burden.
    In evaluating the sufficiency of the evidence on appeal, appellate courts
    generally apply the familiar substantial evidence test. Under that test, an appellate
    court must view the evidence in the light most favorable to the court‟s judgment,
    giving it the benefit of every reasonable inference and resolving all conflicts in its
    favor. (Bickel v. City of Piedmont (1997) 
    16 Cal. 4th 1040
    , 1053.) The appellate
    court must “presume every fact in support of the judgment the trier of fact could
    have reasonably deduced from the evidence. [Citation.] If the circumstances
    1       All further unlabeled statutory references are to the Welfare and Institutions
    Code.
    1
    reasonably justify the trier of fact‟s findings, reversal of the judgment is not
    warranted simply because the circumstances might also reasonably be reconciled
    with a contrary finding. [Citation.] „A reviewing court neither reweighs evidence
    nor reevaluates a witness‟s credibility.‟ [Citation.]” (People v. Albillar (2010) 
    51 Cal. 4th 47
    , 60.)
    However, as our courts of appeal have explained, where, as here, the trier of
    fact has found that the party with the burden of proof did not carry that burden, “it
    is misleading to characterize the failure-of-proof issue as whether substantial
    evidence supports the judgment. This follows because such a characterization is
    conceptually one that allows an attack on (1) the evidence supporting the party
    who had no burden of proof, and (2) the trier of fact‟s unassailable conclusion that
    the party with the burden did not prove one or more elements of the case
    [citations]. [¶] Thus, where the issue on appeal turns on a failure of proof at trial,
    the question for a reviewing court becomes whether the evidence compels a
    finding in favor of the appellant as a matter of law. [Citations.] Specifically, the
    question becomes whether the appellant‟s evidence was (1) „uncontradicted and
    unimpeached‟ and (2) „of such a character and weight as to leave no room for a
    judicial determination that it was insufficient to support a finding.‟ [Citation.]”
    (In re I.W. (2009) 
    180 Cal. App. 4th 1517
    , 1528; see Meister v. Mensinger (2014)
    
    230 Cal. App. 4th 381
    , 395; Dreyer’s Grand Ice Cream, Inc. v. County of Kern
    (2013) 
    218 Cal. App. 4th 828
    , 838 [same]; Valero v. Board of Retirement of Tulare
    County Employees’ Assn. (2012)

    , 966; Shaw v. County of
    Santa Cruz (2008)

    , 279 [same]; Caron v. Andrew (1955) 
    133 Cal. App. 2d 402
    , 409.)
    Notably, these appellate decisions relied on our decision in Roesch v. De
    Mota (1944) 
    24 Cal. 2d 563
    . There, after explaining that the trial court had found
    that the plaintiffs had failed to sustain their burden of proving a certain fact by a
    2
    preponderance of the evidence, we stated: “The problem here is not whether the
    appellants on the issue . . . failed to prove their case by a preponderance of the
    evidence. That was a question for the trial court and it was resolved against them.
    The question for this court to determine is whether the evidence compelled the
    trial court to find in their favor on that issue. These appellants contend that the
    testimony of [their witness] was uncontroverted and that it required a finding in
    their favor. It may be assumed that his testimony was uncontradicted and
    unimpeached, but it would not necessarily follow that it was of such a character
    and weight as to leave no room for a judicial determination that it was insufficient
    to support a finding in favor” of the appellants. (Id. at pp. 570-571, italics added.)
    The same rules apply where the evidence consists of expert opinion. It is
    well established that a trier of fact is “not automatically required to render a
    verdict [that] conforms to . . . expert opinion,” even if “unanimous.” (People v.
    Drew (1978) 
    22 Cal. 3d 333
    , 350; see People v. Samuel (1981) 
    29 Cal. 3d 489
    , 498
    [trier of fact “is not required to accept at face value a unanimity of expert
    opinion”].) “To hold otherwise would be in effect to substitute a trial by „experts‟
    for a trial by jury . . . .” (People v. Wolff (1964) 
    61 Cal. 2d 795
    , 811.) As we have
    explained, “[t]he value of an expert‟s opinion depends upon the quality of the
    material on which the opinion is based and the reasoning used to arrive at the
    conclusion.” (People v. Marshall (1997) 
    15 Cal. 4th 1
    , 31-32.) In other words,
    “ „[e]xpert evidence is really an argument of an expert to the court, and is valuable
    only in regard to the proof of the facts and the validity of the reasons advanced for
    the conclusions.‟ ” (People v. Bassett (1968) 
    69 Cal. 2d 122
    , 141.) Thus, as a
    general rule, the trier of fact remains free to reject even uncontradicted expert
    testimony after considering the expert‟s opinion, reasons, qualifications, and
    credibility, so long as it does not act arbitrarily. (People v. McDonald (1984) 
    37 Cal. 3d 351
    , 371; People v. Johnson (1992) 
    3 Cal. 4th 1183
    , 1231-1232; Foreman
    3
    & Clark Corp. v. Fallon (1971) 
    3 Cal. 3d 875
    , 890.) The trier of fact‟s decision in
    this regard is binding on an appellate court unless the trier of fact could not, in
    light of the record, reasonably reject the expert‟s testimony. (
    Samuel, supra
    , at p.
    506; 
    Drew, supra
    , at pp. 350-351.) Under the preceding authorities, the questions
    here are whether the juvenile court could not have reasonably rejected Dr.
    Kojian‟s opinion and whether the weight and character of the evidence compelled
    the court to find that R.V. had sustained his burden to show incompetency.
    2. The Evidence Does Not Compel a Finding of Incompetence.
    According to the majority, reversal is necessary because the juvenile court
    could not reasonably have rejected the opinion of forensic psychologist Haig J.
    Kojian that R.V. was not competent to proceed. For reasons that follow, I
    disagree.
    Under the two prongs of section 709, subdivision (a), it was R.V.‟s burden
    to prove by a preponderance of evidence that he lacked either “sufficient present
    ability to consult with counsel and assist in preparing his . . . defense with a
    reasonable degree of rational understanding,” or “a rational as well as factual
    understanding, of the nature of the charges or proceedings against him.”
    Regarding the latter prong, in the “Opinion” section of his written report, Dr.
    Kojian expressed, not a firm conclusion, but uncertainty, stating that he
    “question[ed] whether [R.V.] fully knows or understands what is occurring.”
    (Italics added.) He based his uncertainty on the various statements R.V. had made
    about the reason for his detention. In his report, after setting forth those
    statements, Dr. Kojian stated: “It appeared to me that [R.V.] was confused and
    didn‟t know what was going on.” However, the juvenile court disagreed with Dr.
    Kojian‟s reasoning, explaining: “Given the statements that the minor had said to
    Dr. Kojian and Dr. Kojian interpreted them as confusion, but knowing that the
    4
    minor had been released on [the home supervision program], and also knowing
    what the minor had allegedly done, and [that each] of his responses were
    appropriate, such as messing up my house and not going to school, because he had
    refused to go to school, which appeared to have been allegedly the — at least was
    alleged to have been the genesis of what ended up in the charged offenses.”
    Viewing the evidence in the light most favorable to the court‟s decision, and
    giving that decision the benefit of every reasonable inference and resolving all
    conflicts in its favor, I cannot find that the court unreasonably rejected Dr.
    Kojian‟s interpretation.
    Moreover, Dr. Kojian‟s testimony at the competency hearing regarding this
    prong was at least as equivocal as the statements in his report, if not more so.
    When directly asked whether R.V. “lack[ed] a rational [as] well as factual
    understanding of the nature of the charges and proceedings against him,” Dr.
    Kojian did not reply with a clear or unqualified “yes.” Instead, he replied, “I think
    it is limited, yes.” Dr. Kojian‟s testimony that R.V. had a “limited” understanding
    did not compel the juvenile court to find that R.V. had proved by a preponderance
    of the evidence that he “lack[ed]” the requisite understanding, which is the
    standard under section 709, subdivision (a).
    Indeed, parts of Dr. Kojian‟s report affirmatively supported the conclusion
    that R.V. possessed the requisite understanding. The report observed that R.V.
    “knew, in general, the meanings of guilty or not guilty,” that the former “means he
    is responsible” and the latter means he “could be released home,” that “the court
    makes a decision,” and that “misdemeanors are less serious than felonies.” The
    juvenile court expressly mentioned the last of these observations in explaining
    why it did not accept Dr. Kojian‟s opinion. Moreover, the record also shows that
    when advised of his rights upon his arrest, R.V. invoked his right to silence.
    Viewing the evidence in the light most favorable to the court‟s decision, giving
    5
    that decision the benefit of every reasonable inference and resolving all conflicts
    in its favor, the weight and character of Dr. Kojian‟s opinion was not such that the
    juvenile court acted unreasonably in finding that R.V. failed to sustain his burden
    of proof on the second prong of section 709, subdivision (a).
    The majority acknowledges that R.V. invoked his right to silence after
    being advised of his rights, that he was aware generally that a misdemeanor was
    less serious than a felony, that a judge makes decisions, and that being guilty
    means he is “ „responsible.‟ ” (Maj. opn., ante, at p. 41.) The majority also
    “[a]dmit[s]” that “some of” R.V.‟s statements about the reasons for his detention
    were “explainable,” “understandable,” and, “as the [juvenile] court pointed out,”
    an “arguably . . . accurate reflection of some of the factual underpinnings of the
    charges against him.” (Maj. opn., ante, at p. 42.) The majority nevertheless
    declares that R.V.‟s statements failed to “provide a reasonable basis” for rejecting
    Dr. Kojian‟s opinion because they “were limited and incomplete.” (Maj. opn.,
    ante, at p. 41.) According to the majority, “most of” R.V.‟s statements “reflected
    ignorance of, or confusion regarding, many of the significant features of a juvenile
    adjudication,” including the functions of defense counsel and the prosecutor, the
    differences between a plea bargain and a trial, and the types of decisions that a
    juvenile court judge makes. (Ibid.) The majority also asserts that, according to
    Dr. Kojian‟s report and testimony, R.V. “seemed to misunderstand what was
    meant by a criminal charge” and “exhibited no awareness of the most important
    facts underlying the charges.” (Maj. opn., ante, at p. 42.) “On this record,” the
    majority declares, R.V.‟s statements “suggesting” that he “understood some
    features of a juvenile proceeding generally” and was not confused about what was
    happening did not provide a reasonable basis for questioning Dr. Kojian‟s opinion.
    (Maj. opn., ante, at p. 42.)
    6
    For several reasons, I disagree with the majority‟s analysis. First, as
    explained above, insofar as the record shows that Dr. Kojian based his opinion
    regarding R.V.‟s confusion on statements that, as the majority “[a]dmit[s],” were
    “explainable,” “understandable,” and an “arguably . . . accurate reflection of some
    of the factual underpinnings of the charges against” R.V. (maj. opn., ante, at p.
    42), the juvenile court could reasonably question Dr. Kojian‟s reasoning. Second,
    for reasons explained above, the juvenile court could reasonably conclude that Dr.
    Kojian‟s opinion regarding R.V.‟s confusion was far more equivocal and uncertain
    than the majority suggests. As noted earlier, in the “Opinion” section of his
    report, Dr. Kojian stated that he “question[ed] whether [R.V.] fully knows or
    understands what is occurring.” At trial, Dr. Kojian testified, not that R.V. lacked
    the requisite understanding, but that he had a “limited” understanding of the nature
    of the charges and proceedings against him. Third, although, as the majority
    notes, R.V. told Dr. Kojian he did not know what a judge makes decisions about
    or what “the duty and function of the DA” are, the majority fails to note that R.V.
    also told Dr. Kojian that he had “never thought” about the first question and “had
    never had the time to think about” the second. Given this explanation, the juvenile
    court could have reasonably questioned whether R.V.‟s asserted lack of
    knowledge about certain legal matters, notwithstanding his understanding of other
    legal matters, indicated confusion and incompetence. Fourth, and finally, the
    majority‟s explanation for concluding that the statements in the record showing
    R.V.‟s understanding of the legal process are too “limited and incomplete” to
    sustain the juvenile court‟s decision (maj. opn., ante, at p. 41) is inconsistent with
    the applicable standard of review, which requires us to view the evidence in the
    light most favorable to the juvenile court‟s judgment, to give that judgment the
    benefit of every reasonable inference, and to resolve all conflicts in its favor.
    Applying this standard, and in light of the preceding discussion, I do not agree that
    7
    the juvenile court, which itself had the opportunity to observe R.V., acted
    unreasonably in rejecting Dr. Kojian‟s opinion.
    Regarding the first prong of section 709, subdivision (a), Dr. Kojian stated
    in his written report: “I . . . believe that in his current condition [R.V.] doesn‟t
    have the capacity to meaningfully or rationally cooperate with counsel in the
    preparation of a defense, or to assist counsel in a meaningful or rational manner.”
    At the hearing, the juvenile court explained that it did “not accept” Dr. Kojian‟s
    opinion on this issue “partly because the doctor was not able to fully determine
    whether there was malingering and was unable to complete the Rey . . . test” for
    malingering. Significantly, Dr. Kojian‟s report itself provided a basis for the
    juvenile court‟s reliance on this consideration in rejecting Dr. Kojian‟s opinion;
    the report noted five separate times that R.V. “refused to take any tests,” and
    characterized this refusal as “[u]nfortnate[]” four of those times. As specifically
    relevant to the malingering issue, Dr. Kojian stated in his report: “I tried a few
    times to get him to comply [with my request for testing] but he refused noting „I
    just don‟t feel I have to do this.‟ I, even, asked him if he wouldn‟t mind taking
    just one, little test (I was trying to give him the REY 15-item to rule out
    malingering) but he refused.” After responding to a few “basic items,” R.V.
    “refused to answer any other questions and said „I‟m not going to say anything
    else. I am just trying to get help.‟ ” If Dr. Kojian believed that R.V.‟s refusal to
    take any tests was significant — and it is clear from the statements in his report
    that he did — then surely the juvenile court did not act unreasonably in also
    finding it significant. (See maj. opn., ante, at p. 41.)
    The majority‟s explanation for finding otherwise is unpersuasive. (Maj.
    opn., ante, at p. 2.) According to the majority, Dr. Kojian stated during his
    testimony that “he was „100 percent sure‟ of his opinion” that R.V. was not
    malingering “notwithstanding” R.V.‟s refusal to submit to testing. (Maj. opn.,
    8
    ante, at p. 40.) However, the record indicates that this statement related, not to
    R.V.‟s refusal to take a test for malingering or to Dr. Kojian‟s opinion on that
    subject, but to R.V.‟s refusal to take “any cognitive function test.” Later, in
    expounding on what made him believe that R.V. “flunked” the statutory
    competency test, Dr. Kojian stated rather equivocally, “It didn‟t seem to me that
    [R.V.] was attempting to malinger his impairment.” At the end of the direct
    examination, when asked specifically about malingering, Dr. Kojian again
    equivocally responded, “it didn‟t seem to me to be malingering.” More broadly,
    notwithstanding the statement the majority cites, Dr. Kojian later expressed
    notably less certainty about his opinion regarding R.V.‟s competence, indicating
    that, “to a reasonable degree of psychological certainty,” it was “probably
    correct.” To be sure, the majority‟s “context[ual]” reading of the equivocation in
    Dr. Kojian‟s remarks — that it “demonstrated an attempt to express his opinion
    within professional parameters,” rather than “any reservations in his views” (maj.
    opn., ante, at p. 40) — is plausible. But the question here is not how we, as an
    appellate court, interpret Dr. Kojian‟s remarks de novo on a cold record, but
    whether the contrary interpretation of a juvenile court that actually saw Dr. Kojian
    testify and observed R.V. in person is unreasonable. In my view, the statements
    the majority cites do not establish that the juvenile court acted unreasonably in
    considering a factor that Dr. Kojian himself expressly noted numerous times in his
    report — R.V.‟s “unfortunate[]” refusal to submit to testing.
    Moreover, in other respects, Dr. Kojian‟s report and testimony furnished
    affirmative support for the juvenile court‟s assessment of Dr. Kojian‟s opinion
    regarding R.V.‟s ability to assist counsel. At the outset, the report stated that, after
    being told of the interview‟s purpose and receiving various advisements — that
    the interview was nonconfidential and voluntary and that a report would be sent to
    the court for use “in the current matter” — R.V. “noted that he understood the
    9
    scope and intent of testing and volunteered to be interviewed.” According to the
    report, R.V.‟s “grooming and hygiene were intact,” and he “was, largely, oriented
    and knew the day, date and location.” R.V. told Dr. Kojian that “[h]e was
    involved in counseling and did find it to be helpful.” R.V.‟s mother told Dr.
    Kojian that R.V. “was able to meet developmental milestones on a timely basis.”
    As previously noted, the report observed that R.V. “knew, in general, the
    meanings of guilty or not guilty,” that the former “means he is „responsible‟ ” and
    the latter means he “could be released home,” that “the court makes a decision,”
    and that “misdemeanors are less serious than felonies.” In a section entitled
    “Conclusion and Opinion,” the report stated that R.V.‟s “thinking appeared to be
    impaired” (italics added), but then immediately explained that R.V.
    “[u]nfortunately . . . [had] refused to take any tests” that would provide “objective
    measures” of his functioning and had been “rather disinterested in answering
    questions.” It also explained that R.V.‟s apparent cognitive issue did not “appear”
    to be “developmental in nature” and might have resulted from drug use.
    At the hearing, Dr. Kojian stated that he did not know whether R.V. was
    “intellectually impaired.” When asked whether R.V. was “cognitively impaired,”
    Dr. Kojian responded equivocally: “My assessment of him was that there was
    some type of cognitive process going on that did appear to be evidence for some
    type of cognitive impairment.” Dr. Kojian later testified that if R.V.‟s cognitive
    issue was “substance induced in nature, then it might self-correct,” that “you don‟t
    need to do anything except sit around and wait,” and that “nobody knows” how
    long it would take for the effect of the drugs to “wear off.” The district attorney
    followed up by asking whether R.V. “could be better” than he had been “16 days
    earlier” at the time of the interview. Dr. Kojian first responded, “You‟re correctly
    pointing out that competency isn‟t a static variable . . . , so it changes.” After
    stating his opinion that R.V. was not competent “[o]n the day” of the interview or
    10
    the day the report was signed, Dr. Kojian then noted that he was not responsible
    for the 16-day gap between the interview and the competency hearing, and stated,
    “No doctor can tell how an individual is . . . on the day that they testify on [an]
    assessment that they conducted.” The district attorney then explained that he was
    asking about the time gap because Dr. Kojian had answered “no” when earlier
    asked at the hearing whether, in his opinion, R.V., “sitting here right now, was . . .
    competent.” Dr. Kojian, after reiterating his opinion that R.V. was not competent
    on the day the report was signed, stated: “I don‟t know what his functioning is as
    he sits here today.”
    In summary, the record shows considerable equivocation regarding Dr.
    Kojian‟s opinion, contains affirmative indications of competence, reveals
    justifications for questioning Dr. Kojian‟s reasoning process, and offers a case-
    specific reason for questioning the effect on Dr. Kojian‟s assessment of the 16-day
    gap between the interview and the competency hearing. Of course, as the
    majority‟s discussion demonstrates, there was evidence that could reasonably have
    led the juvenile court to accept Dr. Kojian‟s opinion. Indeed, based on that
    evidence, were I making the competency determination de novo, like the majority,
    I might very well find Dr. Kojian‟s opinion sufficient to sustain R.V.‟s burden of
    proof. But, giving proper deference to the juvenile court‟s decision — viewing the
    evidence in the light most favorable to the court‟s decision, giving that decision
    the benefit of every reasonable inference, and resolving all conflicts in its favor —
    I cannot find that the court acted unreasonably in rejecting Dr. Kojian‟s opinion
    or that the evidence was of such weight and character as to compel a finding of
    incompetence.2
    2      The majority appears to lose sight of the applicable standard of review in
    proclaiming itself to be “[un]persuaded” that Dr. Kojian‟s opinion was
    (footnote continued on next page)
    11
    Finally, for two reasons, I do not agree with the majority that expert
    opinion “holds special significance in the juvenile competency setting,” or that a
    juvenile court, upon finding “flaws” in the “methodology and reasoning” of an
    expert who finds the minor to be incompetent, “should consider appointing a
    second expert to inform [its] view that the first expert‟s opinion is inadequate.”
    (Maj. opn., ante, at pp. 46-47.) First, I see no statutory basis for either statement.
    Regarding the latter, the majority cites no supporting authority of any kind.
    Regarding the former, the majority observes that section 709 requires a juvenile
    court to “appoint an expert, specially qualified in the field of child development,
    when there is substantial evidence raising a doubt regarding the minor‟s
    competency.” (Maj. opn., ante, at p. 46.) However, in adult criminal cases, the
    Penal Code requires a court to appoint an expert — sometimes two — if it “has a
    doubt about the mental competency of a defendant” (People v. Pokovich (2006) 
    39 Cal. 4th 1240
    , 1245), yet expert testimony holds no special significance in such
    cases. It is true that section 709, subdivision (b), specifies that the expert
    appointed in a juvenile case “shall have expertise in child and adolescent
    development, and training in the forensic evaluation of juveniles, and shall be
    familiar with competency standards and accepted criteria used in evaluating
    competence.” But nothing about that mere specification of expertise confers
    “special significance” on an expert‟s opinion in juvenile cases. (Maj. opn., ante, at
    (footnote continued from previous page)
    “undermined” by the exchange about the 16-day gap between the interview and
    the hearing. (Maj. opn., ante, at p. 45.) Under that standard of review, the
    relevant question is whether, in light of the testimony, the juvenile court could not
    reasonably consider this gap as one factor in determining the weight of Dr.
    Kojian‟s opinion. As already explained, on the record here, considering that gap
    would not be unreasonable.
    12
    p. 46.) The majority also cites In re John Z. (2014) 
    223 Cal. App. 4th 1046
    (maj.
    opn., ante, at p. 46), but that decision holds only that a juvenile court unsatisfied
    with an appointed expert‟s written report may not make a competency
    determination without first holding “a formal competency hearing at which [the
    expert can] testify concerning his [or her] report” (In re John Z., at p. 1058).3
    Here, of course, the juvenile court held such a hearing and made its decision only
    after listening to Dr. Kojian‟s testimony.
    Second, the majority‟s statements appear to conflict with well-established
    principles that the majority expressly reaffirms earlier in the same paragraph: a
    juvenile court need not “defer to the opinion of an expert” and “an expert‟s
    opinion is not determinative of the question of competency.” (Maj. opn., ante, at
    p. 46.) In the context of these well-established principles, what does it mean to
    say that an expert‟s opinion has “special significance”? (Maj. opn., ante, at p. 46.)
    How does a juvenile court factor this undefined term into its analysis? Why must
    a court that reasonably declines to defer to the expert‟s opinion because of a
    flawed methodology or reasoning consider appointing another expert to inform its
    view of the first expert‟s opinion? Does such a court err if it does not appoint a
    second expert? In short, the majority‟s statements, in addition to being without
    statutory basis, will create confusion and uncertainty for juvenile courts.
    For the foregoing reasons, I dissent.
    CHIN, J.
    3       Another option, the court stated, was for the juvenile court to have waited
    for the report of another expert it had appointed after expressing dissatisfaction
    with the first report. (In re John 
    Z.¸ supra
    , 223 Cal.App.4th at p. 1058.)
