    Joseph Bennett filed a writ petition challenging the trial court’s
    finding of probable cause (Welf. & Inst. Code, § 6602, subd. (a))1 in a
    Sexually Violent Predators Act (SVPA) (§ 6600 et seq.) proceeding.
    Bennett contends that the trial court committed prejudicial error by
    allowing the admission at the probable cause hearing, through expert
    testimony, of case-specific facts that were inadmissible hearsay under
    People v. Sanchez (2016) 
    63 Cal.4th 665
     (Sanchez). Because
    consideration of inadmissible case-specific facts was central to the trial
    court’s finding of probable cause, we conclude that the writ petition
    must be granted.
    BACKGROUND
    Prior to the August 2017 probable cause hearing, the People filed
    a petition to commit Bennett as a sexually violent predator (SVP). At
    the time, Bennett was nearing the end of a seven-year sentence for
    failing to register as a sex offender (Pen. Code, § 290, subd. (b)) in 2012.
    Bennett was initially evaluated by two psychologists, one of whom
    opined that Bennett met the criteria to be considered an SVP, while the
    other disagreed. Pursuant to section 6601, subdivision (e), Bennett was
    reevaluated by two different psychologists, Douglas Korpi and
    Christopher Matosich. Both Korpi and Matosich prepared reports
    concluding that Bennett met the criteria for an SVP.2
    Expert reports
    Predicate offenses
    The reports noted that Bennett had been convicted of “sexually
    violent offenses” (§ 6600, subd. (b)) with respect to two victims. In
    August 1986, on two separate occasions, Bennett broke into a house
    late at night and raped a woman inside. On both occasions, Bennett
    1     All further statutory references are to the Welfare and
    Institutions Code unless otherwise indicated.
    2      Bennett’s request for judicial notice, filed August 31, 2018, is
    granted to the extent it requests judicial notice of the trial court record
    in this matter, and is denied in all other respects.
    2
    was under the influence of alcohol. He was convicted of rape and other
    offenses. Bennett was also convicted of a March 1986 burglary; he later
    acknowledged that this burglary involved an attempted rape. In 1987,
    Bennett was sentenced to a total of 42 years 4 months in state prison.
    He was released in 2008.
    The 2012 incident
    Korpi’s report recited the contents of a July 2012 Whittier Police
    Department report, while Matosich’s report cited a probation report
    containing essentially the same information. According to the police
    report, on July 2, 2012, a 32-year-old woman spoke to an investigating
    officer regarding an alleged sexual assault. The woman told the officer
    that, on July 1, 2012, she was waiting for a bus when a white man in
    his 50’s offered to give her a ride in his pickup truck. The woman
    accepted, and the man told her he first needed to go to his home in
    Whittier to pick up some things. When they got to the house in
    Whittier, she helped the man carry in several bags. He showed her
    around the house and when they got to a bedroom, he closed the door,
    unzipped his pants, and exposed himself. The woman said, “Stop,” but
    the man forced himself on her, made her orally copulate him, and had
    vaginal intercourse with her. The man then told her to take a shower.
    The woman left the house and caught a bus home, and went to the
    hospital the next day.
    After reporting the incident to police, the woman identified
    Bennett’s house, and picked him out of a photographic lineup. A search
    warrant was served at the house and Bennett was arrested. According
    to the police report, when Bennett was arrested, his cell phone had
    images of what appeared to be child pornography. Bennett was not
    registered as living at the house in Whittier, but instead was registered
    as living at another house in a nearby community.
    Bennett was charged with forcible rape, forcible oral copulation,
    possession of child pornography, and failing to register. The
    prosecution eventually dismissed the two rape-related counts because,
    after repeated attempts, they were unable to relocate the alleged
    3
    victim. In August 2013, Bennett was acquitted of the child
    pornography charge, but was convicted of failing to register, which does
    not qualify as a sexually violent offense. (See § 6600, subd. (b).)
    Bennett consistently denied having nonconsensual sex with the
    woman. In an interview conducted by Korpi, Bennett stated that he
    met the woman at a gas station and they smoked methamphetamine
    together. She then went back to the house with him, where, according
    to Bennett, she willingly performed oral sex on him. Bennett claimed
    that while she was at the house, the woman, without his knowledge,
    took $1,800 in cash that his father kept there. Bennett claimed that
    the woman likely reported a sexual assault ‘“to cover her tracks.”’
    Matosich’s report also noted that Bennett denied raping the woman.
    Expert conclusions
    Korpi diagnosed Bennett with “other specified paraphilic disorder
    (coercive type).”3 Korpi wrote that, “Had he been arrested only for the
    offenses in 1986, I would have been reluctant to term him as serial
    rapist inasmuch as the behavior occurred over a period of less than six
    months and substance abuse was so prominent during this period of
    time. At sole issue in this case is whether or not we believe the 2012
    rape allegations.” Korpi noted that the allegations had been dismissed,
    but, based on the circumstances and allegations of the 2012 incident,
    Korpi “tend[ed] to believe the victim,” and therefore found that the
    “rape behavior extended between 1986 and 2012.”
    Korpi further opined that Bennett was likely to engage in
    sexually violent criminal behavior as a result of his mental disorder.
    He based this opinion largely on the use of diagnostic tools, the Static-
    3     “‘“The term paraphilia denotes any intense and persistent sexual
    interest other than sexual interest in genital stimulation or
    preparatory fondling with phenotypically normal, physically mature,
    consenting human partners.” [Citation.]’ [Citation.]” (People v.
    Burroughs (2016) 
    6 Cal.App.5th 378
    , 392, fn. 3 (Burroughs), quoting
    Couzens & Bigelow, Cal. Law and Procedure: Sex Crimes (The Rutter
    Group 2016) § 14:2, p. 14-10.)
    4
    99R and the Static-2002R, that estimate a defendant’s risk of reoffense
    based on various risk factors. Bennett received a score of seven on the
    Static-2002R and six on the Static-99R, both in the “well above
    average” range for risk to reoffend.
    Matosich also diagnosed Bennett with “other specified paraphilic
    disorder--non-consent,” noting that Bennett had sexually assaulted
    women who were strangers, and was detained for indecent exposure
    when he was 16. Matosich further found that Bennett was likely to
    engage in sexually violent predatory criminal behavior as a result of his
    diagnosed mental disorder. Matosich rated Bennett as a five on the
    Static-2002R (“above average risk”), and a six on the Static-99R (“well
    above average risk”). In determining Bennett’s risk of reoffending,
    Matosich considered the 2012 incident, finding Bennett had “not been
    in the community for a significant period of time sex offense free”
    following his 2008 release from prison.
    Probable cause hearing
    Preliminary matters
    Prior to the probable cause hearing, Bennett’s counsel filed a
    motion in limine to exclude any evidence of the alleged 2012 rape or
    forced oral copulation. He argued that any record of the 2012 incident
    was case-specific hearsay not subject to a hearsay exception, and
    therefore was inadmissible under Sanchez.
    Bennett’s counsel raised the same argument at the beginning of
    the probable cause hearing, objecting to any mention of a rape
    allegation in 2012, and asking the court to prohibit expert
    consideration of the 2012 incident. The trial court overruled the
    objection in part, finding that the experts could properly rely on the
    2012 arrest report in formulating their opinion. The court stated that
    it would determine admissibility of the details in the report during the
    course of the hearing.
    The hearing
    The details underlying Bennett’s prior convictions for sexually
    violent offenses -- the two separate rapes occurring in August 1986 --
    5
    were established at the hearing by introduction and admission of a
    “section 969b packet.” (Pen. Code, § 969b.)
    Korpi and Matosich both testified at the hearing. Their
    testimony was consistent with the contents of their reports.
    When asked the basis for his determination that Bennett suffers
    from a paraphilic disorder, Korpi responded, “Primarily the arrests in
    ’86 and in 2012.” When questioned further about how the incidents
    factored into his opinion, Korpi noted there were “sexually aggressive
    act[s]” and “intense sexual activity” with respect to the 1986 offenses.
    Korpi reiterated that he also considered the alleged rape from 2012. In
    describing the 2012 incident, Korpi stated Bennett “was interested in
    forceful sexual conduct against somebody’s will. . . . She was a
    stranger.” The trial court overruled a hearsay objection and motion to
    strike. It thereafter stated, “I’m allowing the testimony to the extent
    that it does pertain to fact-specific information. I’m [admitting] it for
    the limited purpose of explaining Dr. Korpi’s opinion.”
    Korpi continued to testify regarding the 2012 incident and its
    importance to his opinion. Discussing Bennett, Korpi stated: “Had he
    been arrested in only ’86, I would have been reluctant to say he was a
    serial rapist, especially given the substance use.” Korpi noted that
    Bennett displayed rape-related behavior between March and August
    1986, “[a]nd for a diagnosis we want usually a six-month period, and
    really for rapists, much longer typically. And when you have substance
    abuse and only a five-month period, that leads you -- if I didn’t have the
    2012, I probably wouldn’t make the diagnosis. It’s too murky.” Korpi
    further testified that Bennett was sexually aroused by acting against a
    woman’s will; he based this opinion on the 1986 incidents and the 2012
    incident, “[j]ust so many repeated violations of women.” When asked
    about the importance of the 2012 incident to his diagnosis of
    paraphilia, Korpi responded, “It makes or breaks the case for me.”
    In his testimony, Matosich confirmed that he found Bennett had
    a diagnosable mental disorder that predisposed him to the commission
    of criminal sexual acts. Matosich’s diagnosis of a paraphilic disorder
    6
    was “based upon a pattern of offending in sexually aberrant ways over
    significant periods of time. I saw indications from 1986 through 2012
    where there was behavior that supports sexually deviant fantasies and
    urges.” The trial court overruled an objection as to testimony regarding
    the 2012 incident. Matosich was questioned further about the 2012
    incident, and stated that it involved conduct similar to that engaged in
    by Bennett in 1986. Matosich testified, over an overruled objection,
    that the 2012 incident supported his conclusion that Bennett engaged
    in sexual aggression and force upon female victims who were strangers.
    The “underlying facts and the similarities” in the 2012 incident to the
    1986 incidents factored into his opinion that Bennett suffered from a
    paraphilic disorder. Matosich added that Bennett had a lack of
    volitional control, again basing this opinion, in part, on the 2012
    incident. After a long period of incarceration for the 1986 offenses,
    following release “he’s again engaged in sexually aberrant behavior,”
    and “there was demonstrations of aggression that was similar to
    demonstrations of aggressions on earlier counts.”
    After the testimony was given, the court stated, in general terms,
    that it would not admit case-specific facts in the expert reports unless
    they were based on predicate offenses or statements made by Bennett
    himself. After further argument regarding the admissibility of case-
    specific facts, particularly relating to the 2012 incident, the trial court
    took the matter under submission.
    The trial court’s ruling
    The trial court issued its ruling from the bench on August 29,
    2017: it would not consider any case-specific facts contained in the
    experts’ reports, and it was striking any case-specific information
    related by the experts during their testimony.
    Nevertheless, when making its finding of probable cause, the
    trial court emphasized the importance of the 2012 incident to the
    diagnosis of paraphilia: “I’m particularly focusing on the level of
    violence and aggression with regard to Mr. Bennett’s prior conduct and
    secondly with regard to the fact that the last incident was perpetrated
    7
    after a long incarceration. And so I think, in particular, Dr. Korpi’s
    analysis is well supported and I think sufficient for purposes of the
    probable cause hearing.” In response to a question by counsel
    regarding what the court was considering concerning the 2012 incident,
    the court stated: “The fact that there was an offense that was
    perpetrated in 2012. . . . I understand he wasn’t convicted of that, but I
    think the experts could have taken into consideration the underlying
    facts. They did take that into consideration and it was part of their
    analysis, which I found sufficient to support their diagnosis that Mr.
    Bennett suffers from a paraphilic disorder.”
    The court concluded by stating that, based on the evidence
    presented, it found probable cause to believe that Bennett had been
    convicted of a qualifying sexually violent offense, suffers from a
    diagnosable mental disorder, that the disorder makes it likely he will
    engage in sexually violent criminal conduct if released, and that the
    conduct would be predatory in nature.
    Writ petition
    On August 31, 2018, Bennett filed a petition for writ of habeas
    corpus in this court contending that the trial court’s finding of probable
    cause was fundamentally erroneous. Bennett argued that the experts
    improperly relied on the 2012 incident in forming their opinions, that
    the trial court improperly allowed the experts to relate facts from the
    2012 incident, and that the trial court improperly considered the 2012
    incident in making its probable cause determination.
    We issued an order to show cause why Bennett’s petition should
    not be granted, deeming it a petition for writ of mandate or prohibition
    because it directly challenged the propriety of a trial court order. A
    return and a traverse were filed, which we have considered along with
    the petition.
    DISCUSSION
    I. The SVPA
    The SVPA “allows for the involuntary commitment of certain
    convicted sex offenders, whose diagnosed mental disorders make them
    8
    likely to reoffend if released at the end of their prison terms.” (Cooley
    v. Superior Court (2002) 
    29 Cal.4th 228
    , 235 (Cooley).) The
    commitment commences if, following a trial, a “judge or a unanimous
    jury finds beyond a reasonable doubt that the person is an SVP
    [citations].” (Id. at p. 243, fn. omitted.) Section 6600, subdivision (a)(1)
    defines an SVP as “a person who has been convicted of a sexually
    violent offense against one or more victims and who has a diagnosed
    mental disorder that makes the person a danger to the health and
    safety of others in that it is likely that he or she will engage in sexually
    violent criminal behavior.” The People must also prove that the
    sexually violent criminal behavior the offender is likely to engage in
    will be predatory. (People v. Hurtado (2002) 
    28 Cal.4th 1179
    , 1186
    (Hurtado).)
    A. Relevant procedure
    SVP proceedings begin prior to an offender’s release from prison.
    When an offender is determined to be a potential SVP, he or she is
    referred to the State Department of State Hospitals for a “full
    evaluation.” (§ 6601, subd. (b).) The offender is then evaluated by two
    mental health professionals. (§ 6601, subds. (c), (d).) If both
    professionals concur “that the person has a diagnosed mental disorder
    so that he or she is likely to engage in acts of sexual violence without
    appropriate treatment and custody,” the Director of State Hospitals
    forwards a request for a petition for civil commitment. (§ 6601, subd.
    (d).) If only one professional concludes that the offender meets the
    criteria stated in section 6601, subdivision (d), then the Director of
    State Hospitals arranges for further examination by two independent
    mental health professionals. (§ 6601, subd. (e).) If both independent
    professionals concur that the offender meets the criteria, a petition to
    request commitment is filed. (§ 6601, subd. (f).)
    Once the petition is filed a superior court judge reviews it to
    determine whether, on its face, the petition contains sufficient facts
    that, if true, would constitute probable cause “to believe that the
    9
    individual named in the petition is likely to engage in sexually violent
    predatory criminal behavior upon his or her release.” (§ 6601.5.)
    If the judge makes such a finding, a probable cause hearing is
    set. (Cooley, 
    supra,
     29 Cal.4th at p. 245; § 6602.) At the probable cause
    hearing, the judge “shall review the petition and shall determine
    whether there is probable cause to believe that the individual named in
    the petition is likely to engage in sexually violent predatory criminal
    behavior upon his or her release. The person named in the petition
    shall be entitled to assistance of counsel at the probable cause hearing.
    . . . If the judge determines there is not probable cause, he or she shall
    dismiss the petition and any person subject to parole shall report to
    parole. If the judge determines that there is probable cause, the judge
    shall order that the person remain in custody in a secure facility until a
    trial is completed . . . .” (§ 6602, subd. (a).) The probable cause hearing
    is “analogous to a preliminary hearing in a criminal case; both serve to
    ““weed out groundless or unsupported charges . . . and to relieve the
    accused of the degradation and expense of a . . . trial.’”’ [Citation.] Like
    a criminal preliminary hearing, the only purpose of the probable cause
    hearing is to test the sufficiency of the evidence supporting the SVPA
    petition. [Citation.]” (Cooley, at p. 247.)
    B. SVP elements
    1. Conviction of a sexually violent offense
    The first element of an SVP determination is that the person “has
    been convicted of a sexually violent offense against one or more
    victims.” (§ 6600, subd. (a)(1).)4 The existence of prior qualifying
    convictions and the details underlying the commission of these offenses
    may be established by documentary evidence, as made admissible by
    section 6600, subdivision (a)(3). Such documentary evidence includes
    “preliminary hearing transcripts, trial transcripts, probation and
    4     Qualifying predicate offenses under the SVPA are listed in
    section 6600, subdivision (b).
    10
    sentencing reports, and evaluations by the State Department of State
    Hospitals.” (§ 6600, subd. (a)(3).)
    Section 6600, subdivision (a)(3) creates a hearsay exception
    allowing for admission of the documentary evidence described in the
    statute, as well as multiple-level-hearsay statements contained therein,
    to prove a prior qualifying conviction. (People v. Otto (2001) 
    26 Cal.4th 200
    , 207-208 (Otto).) The purpose of this expansive hearsay exception
    is to relieve victims of the burden of testifying about the details of the
    crimes underlying the prior convictions. (Id. at p. 208.)
    “The existence of a prior conviction for a sexually violent offense
    may also be established by documentary evidence” under Penal Code
    section 969b. (People v. Roa (2017) 
    11 Cal.App.5th 428
    , 444 (Roa).)
    “Penal Code section 969b allows the admission into evidence of records
    or certified copies of records ‘of any state penitentiary, reformatory,
    county jail, city jail, or federal penitentiary in which’ the defendant has
    been imprisoned to prove that a person has been convicted of a crime.”
    (Id. at p. 444.)
    2. Diagnosed mental disorder
    The second element, ‘“[d]iagnosed mental disorder,”’ is defined as
    including “a congenital or acquired condition affecting the emotional or
    volitional capacity that predisposes the person to the commission of
    criminal sexual acts in a degree constituting the person a menace to the
    health and safety of others.” (§ 6600, subd. (c).) This element is proven
    by the testimony of mental health experts who render a diagnosis that
    the offender suffers from such a mental disorder. (People v. Yates
    (2018) 
    25 Cal.App.5th 474
    , 478 (Yates).)
    3. Likelihood of reoffending
    The third element the People must prove is that the offender, if
    released, will likely engage in sexually violent criminal behavior due to
    the diagnosed mental disorder. (§ 6600, subd. (a); People v. Roberge
    (2003) 
    29 Cal.4th 979
    , 988.) The offender must “present a substantial
    danger, that is, a serious and well-founded risk, of committing such
    crimes if released from custody.” (People v. Roberge, at p. 988,
    11
    fn. omitted.) The likelihood of a defendant to reoffend is generally
    established by expert testimony, which is usually based on the use of
    diagnostic tools, such as the Static-99, to predict future violent sexual
    behavior. (Roa, supra, 11 Cal.App.5th at p. 445.) The People must also
    show that the sexually violent criminal behavior the offender is likely
    to engage in will be predatory. (Hurtado, 
    supra,
     28 Cal.4th at p. 1186.)
    II. Inadmissible case-specific hearsay
    A. Applicable law
    1. Standard of review and general legal principles
    A trial court’s evidentiary rulings, including those involving the
    hearsay nature of evidence, are reviewed for abuse of discretion.
    (People v. Waidla (2000) 
    22 Cal.4th 690
    , 725.) A trial court ruling that
    rests on an error of law is an abuse of discretion. (People v. Patterson
    (2017) 
    2 Cal.5th 885
    , 894; Yates, supra, 25 Cal.App.5th at pp. 484-485.)
    Hearsay is generally inadmissible, unless it falls under an
    exception. (Evid. Code, § 1200, subds. (a), (b); Sanchez, supra, 63
    Cal.4th at p. 676.) One exception to the hearsay rule is that an expert’s
    testimony has traditionally not been barred when it involves the
    expert’s general knowledge in his or her field of expertise. (Sanchez, at
    p. 676.) Thus, Evidence Code section 801, subdivision (b) allows an
    expert to render an opinion “[b]ased on matter (including his special
    knowledge, skill, experience, training, and education) perceived by or
    personally known to the witness or made known to him at or before the
    hearing, whether or not admissible, that is of a type that reasonably
    may be relied upon by an expert in forming an opinion upon the subject
    to which his testimony relates, unless an expert is precluded by law
    from using such matter as a basis for his opinion.” Evidence Code
    section 802 provides that an expert “may state on direct examination
    the reasons for his opinion and the matter (including, in the case of an
    expert, his special knowledge, skill, experience, training, and
    education) upon which it is based, unless he is precluded by law from
    using such reasons or matter as a basis for his opinion.” On the other
    hand, Evidence Code section 803 provides that the court “may, and
    12
    upon objection shall, exclude testimony in the form of an opinion that is
    based in whole or in significant part on matter that is not a proper
    basis for such an opinion.”
    As noted above, another hearsay exception in SVP proceedings is
    found in section 6600, subdivision (a)(3), which allows for the
    introduction of certain documentary evidence, and multiple-level-
    hearsay statements contained therein, to prove the details of a prior
    qualifying conviction. (Otto, supra, 26 Cal.4th at pp. 207-208.) This
    hearsay exception is limited in scope; it does not allow for the
    introduction of hearsay evidence to prove the details of non-predicate
    offenses under the SVPA or alleged offenses that did not result in
    conviction. (Ibid.; Burroughs, supra, 6 Cal.App.5th at pp. 409-411.)
    2. Sanchez
    Prior to Sanchez, “the general rule was that ‘out-of-court
    statements offered to support an expert’s opinion are not hearsay
    because they are not offered for the truth of the matter asserted.
    Instead, they are offered for the purpose of assessing the value of the
    expert’s opinion.’ [Citation.]” (Burroughs, supra, 6 Cal.App.5th at p.
    405.) Sanchez similarly noted that “some courts have attempted to
    avoid hearsay issues by concluding that statements related by experts
    are not hearsay because they ‘go only to the basis of [the expert’s]
    opinion and should not be considered for their truth.’ [Citations.]”
    (Sanchez, supra, 63 Cal.4th at pp. 680-681.) This practice, however,
    conflicted with the rule that “an expert has traditionally been
    precluded from relating case-specific facts about which the expert has
    no independent knowledge.” (Id. at p. 676.) Sanchez thus declared the
    practice improper, explaining: “When an expert relies on hearsay to
    provide case-specific facts, considers the statements as true, and relates
    them to the jury as a reliable basis for the expert’s opinion, it cannot
    logically be asserted that the hearsay content is not offered for its
    truth. In such a case, ‘the validity of [the expert’s] opinion ultimately
    turn[s] on the truth’ [citation] of the hearsay statement. If the hearsay
    13
    that the expert relies on and treats as true is not true, an important
    basis for the opinion is lacking.” (Id. at pp. 682-683.)
    Sanchez explicitly prohibited the introduction by an expert of
    case-specific hearsay: “What an expert cannot do is relate as true case-
    specific facts asserted in hearsay statements, unless they are
    independently proven by competent evidence or are covered by a
    hearsay exception.” (Sanchez, supra, 63 Cal.4th at p. 686.) Based on
    this holding, the court found that case-specific statements related by a
    gang expert concerning the defendant’s gang membership were
    inadmissible hearsay, because “[t]hey were recited by the expert, who
    presented them as true statements of fact, without the requisite
    independent proof.” (Id. at p. 670.)
    The court in Sanchez noted that expert testimony could properly
    encompass certain matters that would generally be subject to exclusion
    as hearsay: “Our decision does not call into question the propriety of an
    expert’s testimony concerning background information regarding his
    knowledge and expertise and premises generally accepted in his field.”
    (Sanchez, supra, 63 Cal.4th at p. 685.) Further, “Any expert may still
    rely on hearsay in forming an opinion, and may tell the jury in general
    terms that he did so. Because the jury must independently evaluate
    the probative value of an expert’s testimony, Evidence Code section 802
    properly allows an expert to relate generally the kind and source of the
    ‘matter’ upon which his opinion rests. A jury may repose greater
    confidence in an expert who relies upon well-established scientific
    principles. . . . There is a distinction to be made between allowing an
    expert to describe the type or source of the matter relied upon as
    opposed to presenting, as fact, case-specific hearsay that does not
    otherwise fall under a statutory exception.” (Sanchez, at pp. 685-686.)
    3. Sanchez application to SVP proceedings
    Sanchez has repeatedly been held to apply in SVP proceedings.
    (See, e.g., Roa, supra, 11 Cal.App.5th at p. 452; Yates, supra, 25
    Cal.App.5th at p. 483; Burroughs, supra, 6 Cal.App.5th at pp. 410-411;
    People v. Flint (2018) 
    22 Cal.App.5th 983
    , 995-998.)
    14
    In Burroughs, the People established the existence and details of
    the defendant’s qualifying sexually violent offenses through the
    introduction of various materials, certain contents of which fell under
    the section 6600, subdivision (a)(3) exception. (Burroughs, supra, 6
    Cal.App.5th at pp. 409-410.) The documentary evidence, however, also
    contained information regarding the defendant’s personal history,
    including details of uncharged sex offenses the defendant allegedly
    committed. (Id. at p. 410.) The appellate court concluded that this type
    of information should have been excluded: “much of the documentary
    evidence upon which the experts relied was hearsay that was not
    shown to fall within a hearsay exception. The trial court accordingly
    erred by allowing the experts to testify to the contents of this evidence
    as the basis for their opinions.” (Id. at p. 411) Because these
    evidentiary errors were prejudicial, the judgment adjudicating the
    defendant an SVP was reversed. (Id. at pp. 412-413.)
    In Roa, we found that expert testimony regarding case-specific
    facts of the defendant’s qualifying predicate offenses was admissible
    because the facts underlying these offenses were independently proven
    by documentary evidence admitted under section 6600, subdivision
    (a)(3). (Roa, supra, 11 Cal.App.5th at p. 450.) We determined the trial
    court erred, however, in allowing experts to testify regarding
    statements contained in a report prepared by a district attorney
    investigator regarding events that occurred decades earlier, including
    an arrest of the defendant for alleged sexual assault that did not result
    in conviction. (Id. at p. 452.) “The experts in this case testified
    extensively about case-specific facts they obtained from the
    investigator’s reports and treated those facts as true and accurate to
    support their opinions. The investigator’s reports themselves were not
    admitted into evidence, and there is no other evidence of the case-
    specific facts concerning [the earlier incidents]. Admission of expert
    testimony relating case-specific facts about these incidents was error.
    [Citation.]” (Ibid.) In finding prejudice due to this admission of
    hearsay, we noted that the People’s expert testified that he relied on
    15
    the incidents contained in the investigator’s report in diagnosing the
    defendant with paraphilia and other disorders. (Ibid.)
    And, in Yates, we found that the trial court erred in allowing the
    People’s experts to relate case-specific facts drawn from documents
    “that were neither introduced or admitted into evidence, nor shown to
    fall within a hearsay exception.” (Yates, supra, 25 Cal.App.5th at
    p. 485.) We rejected an argument that it was unnecessary to admit the
    documents underlying the experts’ opinions because Sanchez permits
    an expert to rely on hearsay. (Yates, at p. 485.) Even though some of
    the records at issue would have been admissible if introduced under
    section 6600, subdivision (a)(3) because they related to predicate
    offenses, the fact that the records were not properly introduced
    prevented the experts from testifying to their contents. (Yates, at
    pp. 485-486.)
    We further found the experts’ testimony relating case-specific
    hearsay prejudicial: “Without the inadmissible hearsay, the foundation
    for the experts’ opinions goes up in smoke, and with it most of the
    evidence in support of the jury’s SVP finding.” (Yates, supra, 25
    Cal.App.5th at pp. 486-487.) We noted: “‘California has long
    recognized that an expert’s opinion cannot rest on his or her
    qualifications alone: “even when the witness qualifies as an expert, he
    or she does not possess a carte blanche to express any opinion within
    the area of expertise. [Citation.] For example, an expert’s opinion
    based on assumptions of fact without evidentiary support [citation], or
    on speculative or conjectural factors [citation], has no evidentiary value
    [citation] and may be excluded from evidence.” [Citation.] . . .’
    [Citation.]” (Id. at p. 487.)
    B. The instant case
    Bennett contends that the trial court erred by allowing expert
    testimony of case-specific facts relating to the 2012 incident, and that
    the trial court improperly relied on the incident in finding probable
    cause. We agree.
    16
    No documentary or other evidence was used to prove the details
    of the 2012 incident. Instead, the details were introduced through
    testimony of the People’s experts and were also recounted in the reports
    prepared by the experts. The experts, however, had no independent
    knowledge of the 2012 incident. Bennett was interviewed by both
    experts, but he consistently denied having nonconsensual sex with the
    alleged victim. There was no admissible evidence introduced to
    substantiate the 2012 allegation, and accordingly the experts had no
    basis to testify regarding the 2012 incident. An expert may not “relate
    as true case-specific facts asserted in hearsay statements, unless they
    are independently proven by competent evidence or are covered by a
    hearsay exception.” (Sanchez, supra, 63 Cal.4th at p. 686; see also Roa,
    supra, 11 Cal.App.5th at p. 452; Yates, supra, 25 Cal.App.5th at p. 485.)
    Moreover, even if the People had attempted to introduce
    documentary evidence containing details regarding the alleged 2012
    sexual assault, such as the police report or probation report relied on by
    the experts, there does not appear to be any discernible ground for
    deeming the documents admissible. Section 6600, subdivision (a)(3)
    allows for introduction of documentary evidence, and hearsay contained
    therein, but only to prove the details of qualifying predicate offenses.
    (Otto, 
    supra,
     26 Cal.4th at pp. 207-208; Burroughs, supra, 6
    Cal.App.5th at pp. 409-411.) Bennett was never convicted of the
    alleged sexual assault in 2012. And the offense for which he was
    convicted -- failing to register as a sex offender (Pen. Code, § 290,
    subd. (b)) -- is not a qualifying “sexually violent offense” under section
    6600, subdivision (b). The details underlying the offense for which
    Bennett was convicted do not fall under section 6600, subdivision
    (a)(3)’s hearsay exception.
    The trial court made a variety of statements in response to
    Bennett’s hearsay and related Sanchez objections regarding the alleged
    2012 sexual assault. At one point, the trial court stated it was allowing
    testimony regarding the 2012 incident “for the limited purpose of
    explaining Dr. Korpi’s opinion.” This ruling directly conflicted with
    17
    Sanchez’s elimination of the untenable practice of deeming statements
    related by experts “not hearsay because they ‘go only to the basis of [the
    expert’s] opinion and should not be considered for their truth.’
    [Citations.]” (Sanchez, supra, 63 Cal.4th at pp. 680-681.) The trial
    court also overruled other objections made on the basis of Sanchez.
    Eventually, as a preface to its ultimate finding of probable cause,
    the trial court stated it would not consider case-specific facts contained
    in the experts’ reports, and that it was striking any case-specific
    information related by the experts during their testimony. But then
    the court specifically relied on the 2012 incident in issuing its probable
    cause ruling. In finding Korpi’s analysis “well supported and
    . . . sufficient” the trial court focused on “the fact that the last incident,”
    i.e., the 2012 incident, “was perpetrated after a long incarceration.”
    The court reiterated the “fact that there was an offense that was
    perpetrated in 2012” and that the experts took “that into consideration
    and it was part of their analysis, which I found sufficient to support
    their diagnosis that Mr. Bennett suffers from a paraphilic disorder.”
    The 2012 incident was material to the court’s finding of probable
    cause. First, the court found that Korpi’s analysis was supportable
    because of the 2012 incident, and, second, the court found the “fact that
    there was an offense that was perpetrated in 2012” supported both
    experts’ paraphilia diagnoses. Despite the court’s prior statement that
    it was striking all case-specific information, it focused on the 2012
    incident in finding the paraphilia diagnosis adequately proven. This
    consideration of the 2012 incident was improper because the incident
    was never proven by competent evidence and it did not fall under a
    hearsay exception. It was introduced only by way of the experts’
    testimony and reports, and so could not be accorded weight as evidence.
    The significance of the 2012 incident was emphasized by Korpi,
    who, when asked about its importance to his diagnosis of paraphilia,
    responded, “It makes or breaks the case for me.” This testimony
    clarified that, without consideration of the 2012 incident, the
    paraphilia diagnosis would not have been made.
    18
    Consideration of the 2012 incident underpinned the trial court’s
    finding that the People made an adequate showing of the second SVP
    element, that Bennett suffered from a “diagnosed mental disorder” as
    defined by section 6600, subdivision (c). From the trial court’s ruling
    (and Korpi’s testimony), it is clear that if the 2012 incident had not
    been introduced into the proceedings, there would have been no finding
    of probable cause as to this second element. Furthermore, the third
    element -- that the offender will likely engage in sexually violent
    criminal behavior due to the diagnosed mental disorder (§ 6600, subd.
    (a)) -- is necessarily dependent on proof of a diagnosed mental disorder.
    Since admissible evidence to prove both of these elements was lacking,
    the trial court’s finding of probable cause was not supported by
    substantial evidence.5
    III. Probable cause hearing
    The People contend that the evidence presented was sufficient to
    satisfy the burden required at the probable cause hearing, and that the
    hearsay rule and Sanchez should not be applied at a probable cause
    hearing.
    The scope of the probable cause hearing is the same as an
    eventual SVP trial. (Cooley, 
    supra,
     29 Cal.4th at p. 247.) The standard
    the superior court applies when making its ruling at a probable cause
    hearing is whether “a reasonable person could entertain a strong
    suspicion that the petitioner has satisfied all the elements required for
    a civil commitment as an SVP . . . .” (Id. at p. 236.) As already noted,
    the probable cause hearing serves to “““weed out groundless or
    unsupported charges . . . .””” (Id. at p. 247.) The sufficiency of the
    5     Bennett also argues that the experts could not properly rely on
    the 2012 incident as a basis for their diagnosis that Bennett suffers
    from a diagnosable medical disorder that makes it likely he will engage
    in sexually violent criminal conduct. Because we find that there would
    have been no finding of probable cause without the trial court’s
    consideration of the 2012 incident, we need not reach this argument.
    19
    evidence supporting the SVP petition is thus tested at the probable
    cause hearing, as it is at a preliminary hearing in a criminal case.
    (Ibid.)
    The prosecution’s burden at the probable cause hearing is to
    prove all the elements that must be proven at trial. (Cooley, supra,
    29 Cal.4th at p. 257.) The standard of review applied by an appellate
    court in reviewing a probable cause determination is the same as that
    used in reviewing a ruling made at a preliminary hearing. (Ibid.) The
    reviewing court draws every inference in favor of the superior court’s
    factual findings and does not substitute its judgment regarding the
    credibility of witnesses or the weight of the evidence. (Id. at p. 258.)
    “The resolution of mixed questions of law and fact, like probable cause,
    usually is examined independently [citation], and the resolution of a
    question of fact, like any such question underlying probable cause,
    always is examined for substantial evidence [citation].” (Id. at p. 257.)
    Key to the analysis here is whether the trial court’s finding of
    probable cause was supported by substantial evidence. As discussed
    above, the trial court’s ruling was premised on the occurrence of the
    2012 incident. But no admissible evidence was introduced to establish
    the 2012 incident. Thus, even under the relatively lenient standards
    that apply at a probable cause hearing, the trial court’s finding of
    probable cause was not supported by substantial evidence.
    The People argue that formal rules of evidence, including the
    hearsay rule, do not apply at the probable cause hearing, and therefore
    Sanchez has no application at this stage of the proceedings. The People
    cite to In re Parker (1998) 
    60 Cal.App.4th 1453
     (Parker) in support of
    this proposition. In Parker, in a matter of first impression, the court
    examined the procedural nature of a probable cause hearing under the
    then-recently enacted SVPA. (Id. at p. 1455.) The Parker court found
    that the probable cause hearing requires more than a mere “paper
    review,” and that a purported SVP is entitled to “an opportunity to be
    fully heard on the issue of probable cause at that hearing.” (Id. at
    p. 1466.) The Parker opinion also stated: “While we believe the
    20
    prosecutor may present the opinions of the experts through the hearsay
    reports of such persons, the prospective SVP should have the ability to
    challenge the accuracy of such reports by calling such experts for cross-
    examination.” (Id. at pp. 1469-1470.)
    The People contend that the Parker court, by stating that an
    expert’s opinion may be presented through the expert’s hearsay report,
    held that the hearsay rule has no function at a probable cause hearing.
    We do not agree that such a broad pronouncement was made. The
    Parker court further found that the defendant could “challenge the
    facts on which the petition was filed, i.e., the underlying . . . experts’
    evaluations,” including thorough cross-examination of the experts.
    (Parker, supra, 60 Cal.App.4th at p. 1468, fn. omitted.) Cooley made a
    similarly circumscribed statement regarding the admissibility of
    hearsay at the preliminary hearing, citing Parker’s holding that expert
    reports may be presented despite their hearsay nature but that the
    defendant is allowed to challenge the accuracy of the experts’
    evaluations at the hearing. (Cooley, 
    supra,
     29 Cal.4th at p. 245, fn. 8.)
    We believe that a challenge to the admissibility of a key piece of
    evidence upon which the experts relied and testified to is consistent
    with Parker and Cooley’s findings that a defendant may challenge the
    accuracy of the expert reports at the probable cause hearing. The issue
    in this matter is not simply whether the prosecution may present an
    expert’s conclusions at the probable cause hearing through the
    introduction of the expert’s report. Instead, the issue is whether a
    defendant may challenge the introduction of case-specific hearsay by an
    expert who has no personal knowledge of such facts and that is not
    subject to a hearsay exception. Bennett objected to the introduction of
    hearsay evidence -- the 2012 incident -- that formed the basis of the
    experts’ conclusions and the trial court’s finding of probable cause.
    Giving effect to Cooley’s rule that the purpose of the probable cause
    hearing is to “““weed out . . . unsupported charges””” (Cooley, supra, 29
    Cal.4th at p. 247), we find that Bennett could properly challenge the
    21
    admissibility of this case-specific hearsay that was material to the
    probable cause determination.
    Furthermore, to the extent (if any) that Parker could have been
    read as allowing the prosecution at a probable cause hearing to
    introduce otherwise inadmissible case-specific hearsay evidence solely
    through the testimony and reports of its experts, such a reading would
    not pass muster following Sanchez. Sanchez explained that an expert
    may not relate as true “case-specific facts asserted in hearsay
    statements, unless they are independently proven by competent
    evidence or are covered by a hearsay exception.” (Sanchez, supra, 63
    Cal.4th at p. 686.) As discussed above, the 2012 incident was not
    independently proven and it was not subject to a hearsay exception.6
    There was no basis for either expert “to supply case-specific facts about
    which he has no personal knowledge. [Citation.]” (Id. at p. 676.) The
    only method by which the 2012 incident was introduced at the hearing
    was through the testimony of the experts, a practice prohibited by
    6      Proposition 115, adopted by voters in 1990, allowed for
    admissibility of certain hearsay evidence in the analogous setting of a
    preliminary hearing in a criminal proceeding. (Cal. Const., art. I, § 30,
    subd. (b).) In particular, at a preliminary hearing, “the finding of
    probable cause may be based in whole or in part upon the sworn
    testimony of a law enforcement officer . . . relating the statements of
    declarants made out of court offered for the truth of the matter
    asserted.” (Pen. Code, § 872, subd. (b).) An officer may so testify,
    however, only if he or she has “‘sufficient knowledge of the crime or the
    circumstances under which the out-of-court statement was made so as
    to meaningfully assist the magistrate in assessing the reliability of the
    statement.’ [Citation.]” (Correa v. Superior Court (2002) 
    27 Cal.4th 444
    , 452.) This limited rule of hearsay admissibility does not assist the
    People here. Regardless of whether the rule may apply in an SVP
    proceeding, the People’s experts are not law enforcement officers and so
    would not qualify to testify under Penal Code section 872, subdivision
    (b), and, most germanely, they have no independent knowledge of the
    2012 incident or the circumstances under which a police report or other
    statement was made.
    22
    Sanchez. Nothing in the procedural rules gives the trial court at a
    probable cause hearing authority to admit and consider material, case-
    specific hearsay, not subject to an exception, solely on the basis that it
    is related by an expert. We find no justifiable reason to avoid
    application of the hearsay rule or Sanchez simply because we are
    reviewing a finding made at a probable cause hearing.
    It is true that, given the lesser burden for a probable cause
    hearing than what is required at trial -- that a reasonable person could
    entertain a strong suspicion all elements are satisfied, rather than
    proof beyond a reasonable doubt -- not all Sanchez violations at a
    probable cause hearing are likely to be prejudicial. If the only problem
    with admission of the 2012 incident was that it was inflammatory, for
    example, then reversal would likely not be required. There is less
    reason to worry about the possibility of a judge being swayed by the
    inflammatory nature of information at a preliminary stage than there
    is with a trial jury making the ultimate SVP determination. Or, if the
    2012 incident was one of many pieces of information relied on by the
    experts, and was not significant to their opinion or the trial court’s
    probable cause finding, then admission of the evidence would likely not
    be deemed prejudicial.
    But, here, the case-specific hearsay regarding the 2012 incident
    was introduced by the experts, was necessary to their opinions, and
    was critical to the trial court’s ruling. The 2012 incident was not
    independently proven, and there is no reason to believe that any
    admissible proof of the incident would be presented at a trial in this
    matter. Thus, at trial, as here, key evidence needed to establish the
    second and third elements of the SVP determination would be lacking.7
    7     Because we find that Bennett is entitled to relief on this basis, we
    do not reach his alternative contention that he received ineffective
    assistance of counsel at the probable cause hearing. We note, however,
    that Bennett’s counsel repeatedly objected on Sanchez and hearsay
    grounds, the primary basis for our opinion here.
    23
    Since the People failed to meet their burden of proof at the
    probable cause hearing, and the trial court’s finding of probable cause
    is not supported by substantial evidence, the SVP petition must be
    dismissed. (§ 6602, subd. (a).)
    DISPOSITION
    The petition is granted. A writ of mandate hereby issues
    directing the trial court to vacate its August 29, 2017 order finding
    probable cause and to enter a new and different order finding there is
    not probable cause, and to accordingly dismiss the SVP petition
    pursuant to section 6602. The stay of trial court proceedings issued
    November 9, 2018, is dissolved.
