                    1
              N.M., a minor at the time of the events in question, appeals from the trial
court’s entry of judgment against him on his claims of medical malpractice and false
imprisonment after the court granted summary judgment in favor of doctors Michael D.
Schwartz (Schwartz) and Gail Ross (Ross). The doctors had placed or maintained a
mental health hospitalization hold on N.M. following student reports made to N.M.’s
high school that he allegedly posted a threat on social media to shoot up the school.
While N.M.’s brief indicates he has gone on to academic success pursuing premedical
studies in a university degree program, and his opposition to summary judgment included
his emphatic denial that he made any threat, that opposition did not identify any evidence
known to Ross or Schwartz that precluded their probable cause findings to detain N.M.
for continued evaluation and treatment. We therefore affirm the summary judgment
rulings.

                 FACTUAL AND PROCEDURAL BACKGROUND
              N.M. and N.M. Dad filed their complaint in May 2020. After several
rounds of pleadings, including demurrers the trial court sustained as to most of the
plaintiffs’ causes of action, Ross and Schwartz each eventually sought summary
                                                                                       2
judgment on the remaining claims for medical malpractice and false imprisonment.
              According to Schwartz’s separate statement of undisputed facts submitted
in support of his summary judgment motion, which largely mirrored Ross’s separate
statement, a police officer initiated N.M.’s hold at CHCM on May 18, 2019, after N.M.

       1
              N.M. is usually referred to in the trial record as “N.M. Son” to distinguish
him from his father, “N.M. Dad,” who did not file a notice of appeal. (Cal. Rules of
Court, rule 8.100(a)(1).)
       2     College Hospital Costa Mesa’s (CHCM) motion for summary judgment
proceeded in parallel with Ross’s and Schwartz’s motions, but resulted in a separate
judgment, which N.M. also appealed. That appeal is resolved on virtually identical
grounds in N.M. Son v. CHCM, Inc. (G061035, July 13, 2023) [nonpub.opn.]).

                                             2
had been suspended by school authorities when other students reported N.M. “posted on
social media threats of shooting his school.” Hospital records indicated the officer, who
is statutorily authorized to commence an initial detention for purposes of a mental health
evaluation when a person presents a danger to himself or others (Welf. & Inst. Code,
§ 5150, subd. (a)), determined an evaluation was necessary based on the threat described
by the school and his interview with N.M.
              According to the officer’s account, N.M. claimed he posted the threats as a
joke, disclosed a prior depression diagnosis, and described himself as suffering from
body dysmorphia, apparently in relation to his thinning hair. Hospital staff evaluated
N.M. and made an initial determination he met the criteria for a section 5150 hold;
Schwartz evaluated N.M. the next day.
              Schwartz noted the alleged threats, N.M.’s depressed mood, impaired
insight and judgment, and his statement that a medication for major depressive disorder
(Trintellix) had “helped” him in the past. Schwartz concluded continued hospitalization
was necessary, noting “suicidal ideations” and an “impaired level of functioning.”
Schwartz diagnosed N.M. with major depression and anxiety and cautioned that
discharge could “exacerbate illness, depression, anxiety, and medication stabilization”; he
also re-prescribed Trintellix.
              Two days later, on May 21, 2019, Schwartz spoke with N.M.’s mother,
father, and uncle. They informed him N.M. had been prescribed Trintellix in January that
year, was non-compliant in taking it or a Prozac prescription, his preoccupation with his
appearance included threats of self-harm, and he had a recent history of outpatient and
                                             3
partial inpatient mental health treatment.

       3
              N.M.’s opposition to summary judgment offered no facts in his separate
statement to rebut this evidence; instead, he argued Schwartz had offered “Inadmissible
Hearsay.” We address this argument below in relation to expert opinion evidence.

                                                 3
               On May 23, 2019, Schwartz spoke with the psychologist at N.M.’s school,
“who reviewed [with him the] postings describing a desire to potentially harm people at
school,” and N.M.’s allegedly “paranoid thoughts, especially about his mother.” That
same day, according to Schwartz’s account in his summary judgment separate statement
of undisputed facts, N.M. Dad “came to the hospital . . . and demanded to take his son
home,” but Schwartz maintained N.M.’s continued hospitalization was necessary under
                               4
Welfare and Institutions Code section 5250. In his opposition N.M. did not identify any
evidence to rebut Schwartz’s conclusion or to suggest N.M. Dad conveyed information to
Schwartz which might cause him to reconsider a continued hold. Instead of evidence,
N.M. offered his own assessment of Schwartz’s detention decision: “Improper Legal
Conclusion.”
               This pattern continued throughout the remainder of the summary judgment
moving papers and opposition. On May 25-26, Ross evaluated N.M. as the coverage
physician in Schwartz’s absence. She found he had a flat blank affect, “could not
regulate his affect and impulsivity reliably,” lacked empathy, and displayed narcissistic
traits. N.M. presented as “preoccupied, irritable, [and] unpredictable,” with “fragile self-
esteem,” a “poor vocabulary for feeling words,” and “no age-appropriate social skills.”
Ross found him “not fit for discharge” because he posed “a risk of harm to others.”
               In response, N.M.’s separate statement offered no contrary evidence;
instead, he argued Ross’s assessment was not “proof of [him] being a danger to himself
or others.” N.M. levied legal attacks on Ross’s evaluations as “Inadmissible Opinion,”
“Improper Legal Conclusion,” and “Lacks Foundation.”
               Schwartz reevaluated N.M. daily for the next five days, from May 27
through June 1, 2019, and his assessment remained unchanged: “still a danger to others,

       4
             For brevity, further citations to the Welfare and Institutions Code are
shortened to WIC or left undesignated if the context is clear.

                                             4
paranoia, anxiety and impaired insight and judgment.” Schwartz’s diagnoses included
“major depression, rule out psychosis, body dysmorphic diagnosis; rule out OCD, DTO
GD (danger to others, gravely disabled).” In opposition, N.M. asserted defendants bore
“the burden of proof” for the holds, but, with one exception, did not point to evidence to
contradict their evaluations.
               Disputing defendants’ assessment that he posed a risk of harm to himself or
others, N.M. cited in his separate statement the “[d]eclaration[s] of two expert doctors
stat[ing] he was not psychotic.” The two declarations postdated N.M.’s release from the
hospital. The psychologist’s declaration described tests he administered to N.M. in
July 2019, a month or more after N.M.’s discharge; the test results, and “[m]y individual
interviews with [N.M.] did not suggest the presence of a psychotic process.” The other
declaration, by a psychiatrist whom N.M. had seen “since 2018” concluded, based on his
evaluation of an unspecified nature and conducted at an unspecified time, N.M. “is not
psychotic”; rather, he diagnosed N.M. with “anxiety and depression.” N.M. did not
suggest or provide evidence in his separate statement, his declaration (or N.M. Dad’s), or
elsewhere that anyone shared his doctor’s conclusions with Ross or Schwartz at the time
they were treating him. As we discuss more fully below, the trial court excluded the
declarations as untimely.
               Returning to the timeline of treatment that defendants established in their
separate statement of undisputed facts, Schwartz evaluated N.M. on June 3, June 4, and a
final time on June 5, 2019. His assessment remained the same: “paranoid, impaired
insight and judgment, still a danger to others.” Schwartz planned to “[c]ontinue current
treatment plan with therapy and medications,” including Trintellix. Schwartz noted he
“spoke to the mother the prior night about starting an antipsychotic which she refused to
consent to.”

                                              5
              Schwartz’s notes on June 4 reflected that a “Writ” hearing was scheduled
                                    5
two days later (“Writ on 6-6-19”). Following the habeas hearing, the superior court
ordered N.M.’s release from the hospital. N.M. did not include the release order in the
record on appeal or a transcript, settled statement, clerk’s transcript, exhibits, or any other
documentation or evidence from the habeas proceedings, and does not appear to have
included any such evidence in his opposition to summary judgment. His separate
                                                                                             6
statement does not identify or refer to any evidence of any kind from the habeas hearing.
              The trial court granted Ross’s and Schwartz’s motions for summary
judgment, and N.M. now appeals.
                                        DISCUSSION
       1.     Standard of Review
              A motion for summary judgment is properly granted if the moving papers
establish there is no triable issue of material fact, and the moving party is entitled to
                                                   7
judgment as a matter of law. (Code Civ. Proc., § 437c, subd. (c).) We review a trial

       5
               WIC section 5254 provides that a person detained on a 14-day hold under
section 5250 is entitled to an administrative “certification review hearing” or judicial
review, and WIC section 5270.15 requires the administrative hearing or habeas corpus
judicial review under WIC section 5275 when, as here, the hold is extended beyond
14 days to up to 30 days. (WIC, § 5270.15, subd. (b).) Section 5275 provides: “Every
person detained under this part shall have a right to a hearing by writ of habeas corpus for
their release after they or any person acting on their behalf has made a request for
release.”
       6
              Our review of the lengthy appellate record discloses only N.M.’s petition in
the superior court for a writ of habeas corpus and the court’s appointment of the public
defender in the matter. N.M.’s petition requested as the grounds for his petition for
release a determination that he “is not gravely disabled; is not a danger to others.”

Procedure unless specified otherwise or the context makes the cited code clear.

court’s decision to grant summary judgment de novo. (Nava v. Saddleback Memorial
Medical Center (2016) 4 Cal.App.5th 285, 289.)
              When a defendant moves for summary judgment, the defendant has the
initial burden of presenting evidence sufficient to establish either that the plaintiffs cannot
                                                                                                 8
prove one or more elements of their causes of action, or that there is a complete defense.
(§ 437c, subd. (p)(2); Carlsen v. Koivumaki (2014) 227 Cal.App.4th 879, 889.) If the
defendant does so, the burden then shifts to the plaintiffs to produce admissible evidence
demonstrating there is a triable issue of material fact as to the claim or defense. (§ 437c,
subd. (p)(2); Carlsen, at p. 889.) “‘[T]o meet that burden, the plaintiff “may not rely
upon the mere allegations or denials of its pleadings . . . but, instead, shall set forth the
specific facts showing that a triable issue of material fact exists . . . .”’” (Lyle v. Warner
Brothers Television Productions (2006) 38 Cal.4th 264, 274.) Claims or theories
advanced to thwart summary judgment that are not supported by evidence will not raise a
triable issue. (Sangster v. Paetkau (1998) 68 Cal.App.4th 151, 163, 166 (Sangster).)
              N.M. contends the trial court erred in granting summary judgment in favor
of Ross and Schwartz. We address his contentions that the trial court erred first as to his
medical malpractice claim, and then his false imprisonment claim.
       2.     Medical Malpractice
              Because the pleadings frame the relevant issues for purposes of summary
judgment (Wassmann v. South Orange County Community College Dist. (2018)
24 Cal.App.5th 825, 851), we begin with N.M.’s first cause of action in his second

       8
              N.M. failed to designate defendants’ motions for summary judgment to be
included in the record on appeal. It is the appellant’s burden to provide an appellate
record adequate to assess claims of error, including any claim that defendants’ showing in
their moving papers were insufficient to warrant summary judgment. (Ketchum v. Moses
(2001) 24 Cal.4th 1122, 1140-1141.)

                                               7
amended complaint, in which he asserted that Ross and Schwartz committed medical
malpractice.
               N.M. alleged as the gravamen of his claim that defendants “negligently and
carelessly [and] unskillfully examined, misdiagnosed and/or treated . . . N.M. Son,
including but not limited to misrepresentation of facts in order to detain plaintiff for a
much longer period [than necessary] against his will.” N.M. does not identify any
specific, alleged misrepresentation of facts; instead, he seems to suggest through his
pleading that Ross or Schwartz were wrong in concluding he was a proper subject for a
hold. In his malpractice cause of action, N.M. alleged generically that “[i]n their
examination, diagnosis, advice, care, treatment and administration of medical care to
N.M. Son, defendants . . . failed to exercise that degree of skill and care commonly
possessed and exercised by health care providers, medical practitioners, medical doctors,
psychiatric professionals, medical specialists [and] physicians . . . who perform the same
and similar treatment and diagnostic procedures in the area where defendants practice.”
               “The elements of a cause of action for medical malpractice are: (1) a duty
to use such skill, prudence, and diligence as other members of the profession commonly
possess and exercise; (2) a breach of the duty; (3) a proximate causal connection between
the negligent conduct and the injury; and (4) resulting loss or damage.” (Johnson v.
Superior Court (2006) 143 Cal.App.4th 297, 305 (Johnson).)
               To prove a medical malpractice claim, the plaintiff must first establish the
applicable standard of care and then demonstrate that the standard of care was breached.
(Powell v. Kleinman (2007) 151 Cal.App.4th 112, 122 (Powell).) “Because the standard
of care in a medical malpractice case is a matter ‘peculiarly within the knowledge of
experts’ [citation], expert testimony is required to ‘prove or disprove that the defendant
performed in accordance with the standard prevailing of care’ unless the negligence is
obvious to a layperson.” (Johnson, supra, 143 Cal.App.4th 297, 305.) Similarly,
“‘[c]ausation must be proven within a reasonable medical probability based upon

                                              8
competent expert testimony.’” (Dumas v. Cooney (1991) 235 Cal.App.3d 1593, 1603;
see also Bromme v. Pavitt (1992) 5 Cal.App.4th 1487, 1498 [expert testimony required to
establish medical negligence caused patient’s injury].)
              A medical malpractice defendant who supports a summary judgment
motion with applicable expert declarations “‘is entitled to summary judgment unless the
plaintiff comes forward with conflicting expert evidence.’” (Munro v. Regents of
University of California (1989) 215 Cal.App.3d 977, 984-985 (Munro); Powell, supra,
151 Cal.App.4th at p. 123.) Ross and Schwartz both submitted declarations by
board-certified psychiatrists attesting that each complied with the applicable standard of
care while treating N.M. and thus caused him no injury through medical negligence.
              N.M. failed to rebut this evidence. N.M. did not designate individuals he
identified as experts until nearly a month after the date designated for exchange of expert
witnesses, and he ultimately did so only two days before the discovery cutoff date,
leaving defendants no time to depose the witnesses. The trial court therefore properly
struck the declarations submitted by experts who were not timely designated. (Perry v.
Bakewell Hawthorne, LLC (2017) 2 Cal.5th 536, 539.) Inadmissible evidence must be
disregarded and cannot defeat summary judgment. (Id. at p. 543.)
              In any event, the opinions would not have aided N.M. in his opposition to
summary judgment. The opinions his experts rendered were not responsive on the issues
presented regarding N.M.’s malpractice cause of action. Neither expert said anything
about the applicable standard of care, whether Ross or Schwartz met or fell short of that
standard based on the information available to them at the time they formed their
diagnosis, or whether anything Ross or Schwartz did or did not do caused N.M. to suffer
any medical injury. In other words, they focused on N.M., not on Ross or Schwartz. In
fact, neither expert made any mention of Ross or Schwartz in their declaration. In the
absence of any conflicting expert testimony on Ross’s or Schwartz’s performance in

                                             9
relation to a medical standard of care, both were entitled to summary resolution of N.M.’s
medical malpractice claim in their favor. (Munro, supra, 215 Cal.App.3d at p. 985.)
              Invoking the doctrine of res ipsa loquitur, N.M. contends that
“[s]ometimes . . . the medical malpractice is so obvious that [expert opinion as to medical
negligence or causation of injury is] not needed,” as “when a surgeon leaves a sponge in
the patient.” N.M. insists there was such a self-evident breach of “the normal standard of
care” here because “[i]t is illegal to place a minor on a gravely disabled hold (adults only)
no matter what.” (Italics added.) In effect, N.M. seeks to have a presumption of
negligence under the doctrine of res ipsa loquitur (Evid. Code, § 646, subd. (b)) serve as a
substitute for producing evidence of the applicable standard of medical care and breach
of that standard.
              However, the authorities N.M. cites do not establish that a minor may not
be found gravely disabled; indeed, they do not mention minors or distinguish them from
adults. (WIC, §§ 5008, subd. (h)(1)(A), 5270.15, 5350, subd. (e)(1); CACI No. 4002.)
They therefore do not support his contention that the treatment provided by Ross or
Schwartz rose to the level of “self-evident” medical malpractice. N.M.’s reliance on the
doctrine of res ipsa loquitur is therefore without merit.
              In asserting a claim for medical malpractice, N.M. asks that Ross’s and
Schwartz’s conduct be judged by the standards of the medical community, i.e., the
standard of care according to professionals in that discipline. Having provided no
evidence of what that standard was in the form of expert testimony, as was his duty to
defeat summary judgment (Powell, supra, 151 Cal.App.4th at p. 122; Munro, supra,
215 Cal.App.3d at p. 985), N.M.’s medical malpractice claim necessarily failed to
advance past the summary judgment stage.
       3.     False Imprisonment
              The core of N.M.’s false imprisonment claim as alleged in his second
amended complaint is that Ross and Schwartz confined him “against his will or consent

                                             10
or legal right . . . .” False imprisonment is a tort. (Easton v. Sutter Coast Hospital (2000)
80 Cal.App.4th 485, 496.) “The elements of a tortious claim of false imprisonment are:
(1) the nonconsensual, intentional confinement of a person, (2) without lawful privilege,
and (3) for an appreciable period of time . . . .” (Ibid.)
               Under the Lanterman-Petris-Short Act (WIC, § 5000 et seq.), “a person
who is dangerous or gravely disabled due to a mental disorder may be detained for
involuntary treatment.” (Ford v. Norton (2001) 89 Cal.App.4th 974, 979 (Ford).)
Nevertheless, it has long been held that involuntary hospitalization “‘in violation of [the
governing statutes] constitutes false imprisonment.’” (Jackson v. Cedars-Sinai Medical
Center (1990) 220 Cal.App.3d 1315, 1322.)
               The statutes envision incremental detention when necessary. (Ford, supra,
89 Cal.App.4th at p. 979.) The “first step” is a “72-hour treatment and evaluation” hold
authorized by WIC section 5150. (Ford, at p. 979.) Under this code section, certain
officials (including law enforcement and certain medical professionals) are authorized to
bring an individual to a designated mental health facility for evaluation if there is
“probable cause to believe that the person is, as a result of a mental disorder, a danger to
others, or to themselves, or gravely disabled.” (WIC, § 5150, subd. (e).) Depending on
the outcome of the evaluation, various statutes may authorize further detention. (See,
e.g., §§ 5250 [intensive 14-day treatment]; 5270.15 [certification for additional treatment
for “not more than 30 days”]; 5300 [up to 180-day commitment for the imminently
dangerous]; 5352.1 [30-day temporary conservatorship for the gravely disabled]; see
generally Gonzalez v. Paradise Valley Hospital (2003) 111 Cal.App.4th 735, 740, fn. 4
(Gonzalez).)
               Balanced against the safeguards embodied in these statutes, the Legislature
has also recognized that “‘reasonable decisions as to how to control particular patients
should not be chilled, at the time they are made, by the prospect of liability.’” (Johnson
v. County of Ventura (1994) 29 Cal.App.4th 1400, 1410, italics added.) Thus, individuals

                                              11
authorized to detain patients involuntarily, including medical practitioners, “shall not be
held either criminally or civilly liable for exercising this authority in accordance with the
law.” (WIC, § 5278; see, e.g., Heater v. Southwood Psychiatric Center (1996)
42 Cal.App.4th 1068, 1080-1081 (Heater).)
              This language has been construed to mean that no liability can arise when a
medical provider’s decision resulting in an involuntary detention “is supported by
probable cause.” (Jacobs v. Grossmont Hospital (2003) 108 Cal.App.4th 69, 76
(Jacobs); Gonzalez, supra, 111 Cal.App.4th at p. 741.) A critical feature in determining
the existence of probable cause is that a detention decision may not be second-guessed
with alleged facts unknown to the medical provider: “‘Each case must be decided on the
facts and circumstances presented to the [detaining person] at the time of the detention
. . . .’” (Heater, supra, 42 Cal.App.4th at p. 1080, italics added, brackets in original.)
              Here, Ross and Schwartz supported their respective summary judgment
motions with expert witness declarations that, based on the evidence known to Ross and
Schwartz when they evaluated N.M., “all of [N.M.’s] holds were supported by probable
cause.” That does not mean, as N.M. correctly observes, that Ross’s and Schwartz’s
evaluations were dispositive on the question of probable cause—if N.M. submitted
contrary evidence. Indeed, the expert opinions were not even dispositive as medical
assessments given that, as Ross’s expert expressly acknowledged, “health care
professionals [can] differ on a patient’s diagnosis.”
              Nevertheless, the evidence Ross and Schwartz presented did put in issue the
question of probable cause for summary judgment purposes because it was sufficient for
a trier of fact to conclude that probable cause for the holds existed. It was therefore
incumbent on N.M. to present evidence that there was not probable cause to hospitalize
him. A plaintiff may not merely restate allegations from his or her pleadings at this point,
as N.M. does repeatedly in his appellate briefing. At the summary judgment stage, the
case has progressed past “‘mere allegations . . . of [the] pleadings’” to an evaluation of

                                              12
the evidence presented for and against summary judgment. (Brantley v. Pisaro (1996)
42 Cal.App.4th 1591, 1594.)
              Because the existence of probable cause defeats a plaintiff’s case for false
imprisonment (Jacobs, supra, 108 Cal.App.4th at p. 76), once a moving defendant meets
his or her initial burden, as here, “to show the action has no merit” (Grotheer v. Escape
Adventures, Inc. (2017) 14 Cal.App.5th 1283, 1292), the burden of production of
evidence “shifts to the plaintiff to demonstrate the existence of a triable issue of material
fact” (id. at pp. 1292-1293). This can be accomplished by producing “specific evidence,
through affidavits or admissible discovery material, to show that the dispute exists.”
(Bhan v. NME Hospitals, Inc. (9th Cir. 1991) 929 F.2d 1404, 1409.)
              In N.M.’s opposition to summary judgment he did not identify in his
separate statement of facts any information known to Ross or Schwartz, or that they
should have known, which might have negated probable cause to detain N.M. At
summary judgment, the parties’ separate statements are critically important because they
pinpoint evidence for the trial court to consider so it can determine whether there is any
factual conflict that must be resolved by the jury. (See San Diego Watercrafts, Inc. v.
Wells Fargo Bank (2002) 102 Cal.App.4th 308, 315 (San Diego Watercrafts) [evidence
left undisclosed in a party’s separate statement may properly be ignored].)
              Here, N.M.’s opposition to summary judgment did not identify any
evidence that undermined Ross’s or Schwartz’s probable cause assessments supporting
continued detention at the time they made them. Instead, N.M. asserted in a conclusory
fashion in his separate statement that he “has never been [a] danger to others or himself”
and he “did not have any mental disorder.” In making these assertions, N.M. did not set
forth any evidence Ross or Schwartz knew, or should have known, which undermined
their conclusions; he simply labeled them an “Improper Legal Conclusion.” N.M. then
made a general reference to his memorandum in opposition to summary judgment,

                                             13
apparently to suggest it contained “facts that prove the hol[d] was in violation of the
rules,” without specifying any facts.
              Such a presentation does not suffice to defeat summary judgment. The
predicate facts said to support an argument in opposition to summary judgment must be
established by admissible evidence identified in the separate statement. (San Diego
Watercrafts, supra, 102 Cal.App.4th at p. 315.) “[I]n order to avert summary judgment
the plaintiff must produce substantial responsive evidence sufficient to establish a triable
                                                                  9
issue of material fact on the merits of the defendant’s showing.” (Sangster, supra,
68 Cal.App.4th at p. 162-163.)
              Elsewhere in his separate statement, N.M. alluded generally to the
declarations of his “two [expert] doctors” and his contention that the “Habeas corpus
Judge ruled [his] confinement was illegal,” resulting in the order on June 6 for his

       9
              N.M. challenged Ross’s and Schwartz’s showing of probable cause based
on the declarations of their respective expert witnesses. But unlike N.M., the witnesses
provided—and the defendants’ separate statements referenced—the foundational facts
supporting probable cause when N.M. was in Ross’s and Schwartz’s care. An expert
“may rely on various sources of information, including hearsay, in forming an opinion.”
(People v. Rodriguez (2014) 58 Cal.4th 587, 646; Evid. Code, § 801, subd. (b).) This
applies equally to a treating physician evaluating a patient’s mental condition. (People v.
Bona (2017) 15 Cal.App.5th 511, 522 [“exclusion of the challenged evidence would not
have precluded [the doctor] from stating the opinions upon which that evidence was
based”].) Thus, the trial court did not abuse its discretion in finding that N.M.’s
evidentiary objections based on hearsay, foundation, and other grounds failed to derail
summary judgment. (See Sanchez v. Kern Emergency Medical Transportation Corp.
(2017) 8 Cal.App.5th 146, 154 [abuse of discretion standard applies].)

               At best, N.M.’s challenges went to the weight of the evidence, not its
admissibility, and therefore the evidence could be considered in support of summary
judgment. (See Guastello v. AIG Specialty Insurance Co. (2021) 61 Cal.App.5th 97,
105-106 [alleged ‘“weakness in the underpinnings of such [expert] opinions may be
developed upon cross-examination,”’ but ‘“go[] to the weight and credibility of the
testimony,”’ not whether it met “admissibility requirements”].)

                                             14
discharge from the hospital. But the untimely declarations by his doctors were
inadmissible and therefore provided no basis to deny summary judgment.
              Nor did N.M.’s reference to the court’s prior habeas ruling. By statute, the
issue before the trial court in considering a habeas petition for release under WIC
section 5276 is whether “the person requesting release is” (italics added) a danger to
others or to himself or gravely disabled due to a mental disorder: “If the court finds,
(a) that the person requesting release is not, as a result of mental disorder or impairment
by chronic alcoholism, a danger to others, or to himself or herself, or gravely disabled,
(b) that he or she had not been advised of, or had accepted, voluntary treatment, or
(c) that the facility providing intensive treatment is not equipped and staffed to provide
treatment, or is not designated by the county to provide intensive treatment [then] he or
she shall be released immediately.” (Ibid., italics added.)
              The use of the present tense in the statutory language requires us to
conclude that the habeas court’s decision standing alone—without any reference to what
evidence was before the court, or any explanation by the court of its decision—does not
establish that probable cause to legally hold N.M. disappeared at any particular time
before that ruling was made. Thus, the release order on June 6 is not evidence that
probable cause never justified N.M.’s detention, or that a continued hold became
unwarranted at any time before the hearing. In the absence of a triable issue of fact, the
trial court properly granted summary judgment.
              In his appellate briefing, N.M. advances a plethora of other arguments in
opposition to summary judgment, none supported by admissible evidence identified or
referenced in his separate statement in opposition to summary judgment or elsewhere in
his opposition papers. Those unsupported claims, arguments, or theories are therefore
insufficient to defeat summary judgment.
