        Defendant and Appellant.


        Rosalinda C.1 appeals from an order committing her as a mentally retarded person
who is a danger to herself and others to California Psychiatric Transitions, a locked
facility, for one year. (Welf. & Inst. Code, § 6500.)2 Pursuant to legislation passed in
2012, if Rosalinda’s first commitment hearing had been held on or after July 1, 2012, she
could not have been committed for more than six months initially, and then only if the
court found her to be dangerous and in “acute crisis.” (§§ 6500, subd. (c)(2), 4418.7,
subd. (d)(1).) Rosalinda argues that the disparate treatment of mentally retarded
committees based solely on the date of their first commitment violates the equal
protection clause. Rosalinda also challenges the evidentiary basis of the court’s findings
that her mental retardation caused her to have serious difficulty controlling her dangerous

behavior; and that a locked facility was the least restrictive appropriate placement. We
affirm.
                               STATEMENT OF THE CASE
          Rosalinda was first admitted to California Psychiatric Transitions (CPT) under a
section 6500 commitment in 2008. She was recommitted pursuant to section 6500 for
one year from November 15, 2011 to November 15, 2012. On November 13, 2012, the
Alameda County District Attorney’s Office filed the current petition alleging that
Rosalinda C. is mentally retarded and a danger to herself and others, and requesting
renewal of her involuntary commitment to the State Department of Developmental
Services for residential placement for an additional year. (Welf. & Inst. Code, § 6500.)
Rosalinda was ordered to be held at CPT, her existing placement, until the hearing on the
petition.
          Rosalinda opposed the extension of her commitment. The court heard and denied
Rosalinda’s motion to dismiss the petition on equal protection grounds. On February 28,
2013, following a hearing at which four witnesses testified, the court granted the petition
and committed Rosalinda to CPT for suitable treatment and rehabilitation for one year,
until November 15, 2013.
                                 STATEMENT OF FACTS
          Dr. Scott Turpin, M.D., was Rosalinda’s attending psychiatrist at CPT from
November 2011 through September 2012. In preparation for his testimony, Dr. Turpin
reviewed Rosalinda’s CPT medical record.
          Rosalinda was in the main unit at CPT from March 2011 to September 2012, when
she was moved into the Disruptive Behavior Unit because of her assaultive behavior and
some other problems in the main unit. A different psychiatrist was in charge of the
Disruptive Behavior Unit and he made the final decision, in collaboration with the
attending psychiatrist and others, whether a patient was ready to be moved out of the
Disruptive Behavior Unit. So far, Rosalinda had not gained sufficient control of her
assaultive behavior to allow for her transfer back to the main unit.


                                               2
       Based on medical record review, consultation with treatment team members, and
observation, in November 2011 Dr. Turpin diagnosed Rosalinda with schizophrenia,
paranoid type. Schizophrenia is characterized by “positive” symptoms which respond to
treatment, such as auditory and sometimes visual hallucinations, fixed false beliefs, and
significant disorganization of speech and thought. It is also characterized by “negative”
symptoms which do not respond to treatment, such as lack of sociability, lack of
motivation, and flat emotional expression. When Dr. Turpin first began interacting with
Rosalinda, he did not observe symptoms of paranoid schizophrenia. His assessment was
that Rosalinda had been on antipsychotic treatment for some time and at least the positive
symptoms of her disease were under control.
       Based on review of her records, Dr. Turpin also diagnosed her with mild mental
retardation, of which she has a long-standing history. “Her presentation appeared
consistent with that, even simple mental status questions were consistent with low IQ.”
In general, mentally retarded people can exhibit immature coping skills, poor impulse
control, and difficulty managing their behavior, and in November 2011 when Dr. Turpin
first came in contact with her, Rosalinda exhibited all of those traits.
       By September and October of 2012, Dr. Turpin was getting frequent calls from
staff who reported that Rosalinda had hit other patients. She was unable to explain why
she was hitting peers. Occasionally, staff reported that she hit them. This was a change
in Rosalinda’s prior behavior and it seemed to be getting worse. Most recently,
Rosalinda reported that she struck two people the week before the court hearing, and staff
notes corroborated a recent incident of pushing and an attempt to strike another patient on
February 20, 2013. No one had suffered significant injury as a result of being hit by
Rosalinda.
       In Dr. Turpin’s opinion, Rosalinda currently has difficulty managing her assaultive
behavior because of her developmental delay, not her schizophrenia. His opinion was
based on the fact that in the past, Rosalinda had said she “struck because she heard voices
telling her to do that,” but not recently. In fact, she currently denied auditory
hallucinations or delusions. Dr. Turpin had not observed any symptoms of schizophrenia

                                              3
at the time her assaultive behavior began to escalate. At times, Dr. Turpin considered
whether Rosalinda’s failure to respond to staff or to him and her tendency to “just sort of
[stare]” was a symptom of schizophrenia called thought blocking, but he opined it was
also possible “she could be choosing just not to respond.”
       In addition to assaultive behavior, Rosalinda had recently begun to exhibit other
symptoms indicating poor impulse control, such as urinating on herself on purpose in
order to achieve other ends, like avoiding group therapy, and ensuring she was the last in
line for medication or meals. Rosalinda was digging in the trash to look for food, and she
sometimes ate out of the trash. In 2008, when she came into CPT, she weighed over 300
pounds. Since then, she has been on a restricted-calorie diet and has lost significant
weight. Although the trash-digging behavior might be motivated by hunger, Dr. Turpin
had tried other ways to help hungry patients, such as encouraging them to drink water, or
giving them extra portions of vegetables.
       Also, Rosalinda had been throwing tantrums which involved yelling and tossing
chairs. The increase in the frequency of this conduct caused Rosalinda to be removed
from the main unit and placed in the Disruptive Behavior Unit. At the time of trial, this
behavior had begun to lessen.
       At the time of trial, Rosalinda was taking several psychiatric medications
regularly: 50 milligrams of clozapine twice a day and 400 milligrams at night; 60
milligrams of a generic Prozac (fluoxetine) in the morning; and one-half milligram of
generic Ativan (lorazepam), an anti-anxiety medication, twice a day. She also received
additional lorazepam and Thorazine, an older antipsychotic drug, on an as-needed basis.
Dr. Turpin increased Rosalinda’s clozapine dosage in February 2012 in the hope that the
drug’s anti-impulsivity and anti-aggression effects would ease Rosalinda’s difficulty with
impulse control during the day, even though her impulsivity and aggression were the
result of her mental retardation. Rosalinda’s aggressive behavior did seem to improve for
a while before things got worse again in June 2012. On July 3, 2012, Rosalinda reported
she had “not heard voices in about a week,” and Dr. Turpin “didn’t see anything that was
suspicious of auditory hallucinations at that point.”

                                              4
       Rosalinda also engaged in self-injuring behavior. In late August or early
September 2012, Rosalinda sustained a minor injury to her thumb, which became
infected. By the time Rosalinda brought her injured thumb to anyone’s attention, it had
become so infected she had to be hospitalized for several weeks; her thumb was almost
amputated. In the Disruptive Behavior Unit, which had only 12 patients, there was a
better staff-to-patient ratio than in the main unit, generating better supervision.
       In Dr. Turpin’s opinion, Rosalinda was a danger to herself because she had a
history of making suicidal threats. She often threatened to kill herself in an attempt to
manipulate caregivers or her placement situation. However, on February 14, 2013 she
was found with a six-foot strip of cloth, a few inches wide, that appeared to have been
taken from a bedsheet. She said it was an accident—“the sheet had just ripped”—but Dr.
Turpin found the incident worrisome.
       It was also his opinion that Rosalinda was a danger to others “because of the
repetitive hitting at other people, pushing people.” He further opined that Rosalinda had
trouble controlling her dangerous behavior because of her mental retardation. He arrived
at this opinion because he had “not observed symptoms of schizophrenia, the auditory
delusion or disorganized thinking, so it seems more consistent with poor impulse control
associated with her mental retardation.”
       Jeffrey Nagafuji is a case management supervisor at the Regional Center of the
East Bay (the Regional Center). Rosalinda’s case was transferred to Nagafuji’s team in
2008, shortly after she was placed at CPT. Before placement at CPT, she had been in a
number of care home facilities on a short-term basis, and before that, in 2007, she lived
with her family. Rosalinda’s mother requested Rosalinda be placed in a group home.
       The Regional Center tries to place a client in the least restrictive placement
permitted by the client’s behavioral needs and disorders. In Rosalinda’s case, it became
apparent that such placements prior to her move to CPT were not satisfying her mental
health and behavioral needs; a higher level of care was indicated.
       The appropriateness of Rosalinda’s placement is reviewed on a quarterly basis.
The last review involving Nagafuji occurred in August 2012. At that time, CPT appeared

                                              5
to be the most appropriate placement for Rosalinda, given her mental health and
behavioral needs. CPT provides close mental health monitoring and the provision of
psychiatric services on site. These services were not available at a less restrictive
placement. Also, unlocked facilities might not be able to adequately address some
aggressive behaviors. As of the time of trial, there was no board-and-care facility the
Regional Center considered able to meet all of Rosalinda’s diverse needs as well as CPT
did.
         As of August 2012, returning Rosalinda to her mother’s home was not a realistic
option, given Rosalinda’s continued aggressive behavior at CPT. In addition, the
Regional Center staff were concerned about suicide risk and medication compliance
issues if Rosalinda were to be returned to her mother’s home. Previously, Rosalinda’s
placement with her mother had proven inadequate precisely because Rosalinda did not
take her medications, used alcohol, and displayed aggression while at home. It appeared
to Nagafuji that Rosalinda continued to need a higher level of care than could be
provided at home. He drafted a report requesting that Rosalinda be recommitted to CPT
pursuant to Welfare and Institutions Code section 6500. If Rosalinda were able to
display stability for a substantial period of time, the Regional Center staff would consider
transitioning her to a lower level of care such as a board-and-care or group home
placement. To date, Rosalinda had not been able to do that.
         A.C. is Rosalinda’s adoptive mother and biological aunt. Rosalinda lived with
A.C. from age two and a half until age 18, when she went to live in a group home at
A.C.’s request. At the time, individual doctors were giving Rosalinda different
medications and no one was really monitoring them. As a result, Rosalinda began to
throw loud tantrums. Rosalinda did not improve while she was in group or board-and-
care homes, but A.C. noticed an improvement since Rosalinda was at CPT. Rosalinda
appeared calmer and more alert, more like the laughing, talkative, happy person she used
to be.
         A.C. now very much wanted Rosalinda to return home because she missed
Rosalinda. Her plan for caring for Rosalinda at home included getting a psychiatrist for

                                              6
her. Since A.C. worked five days a week from 11:00 p.m. to 7:00 a.m., other relatives
would help care for Rosalinda. A.C. planned to send Rosalinda to Fremont Adult School
to learn independent living skills. School lasted from 9:00 a.m. to 2:30 p.m., Monday
through Thursday. A.C. would “make sure” Rosalinda takes her medications. She was
not afraid of being assaulted by Rosalinda; Rosalinda had never been physically
aggressive to her. If Rosalinda threw a tantrum at home, she would take a walk with
Rosalinda, because that used to help her “a lot,” and she would have Rosalinda play with
her dogs. A.C. would manage Rosalinda’s incontinence by having someone take
Rosalinda to the bathroom every three hours and have Rosalinda drink a bit more during
the day and less at night. If Rosalinda started swatting or hitting people, A.C. would try
to calm her down by talking to her.
       Rosalinda testified on her own behalf. Given a choice, Rosalinda would prefer to
live with A.C. She missed her family and her dogs. If she became agitated, Rosalinda
would ask her mother for the medication she used on an “as needed” basis, or go on a
walk. Rosalinda explained that she hurt her thumb when another girl assaulted her. Staff
saw the incident, pulled the girl away, and cleaned her thumb. The next night, Rosalinda
had a fever when staff took her vitals and she went to the hospital.
       Rosalinda testified regarding the bedsheet incident. The bedsheet tore partway
when it got caught in her thumb and Rosalinda pulled the sheet. She ripped the sheet the
rest of the way for “fun.” She did not plan to hang herself with the sheet.
       Rosalinda never physically hurts anybody; she just taps or swats them. She
behaves this way because she dislikes CPT; she wants to be home and get her freedom
back. Also, she sees that other people get attention for hitting others, and she is jealous
of them. She does not hit to get attention; she just hits when she gets mad at others
sometimes. Lately, she has been trying to stop herself from hitting and it has been
working, although she still hits people.
       At CPT, she copycatted someone else who was digging in the trash. She also digs
through the trash because she is hungry from being on a low-calorie diet. She knows


                                              7
there are other things she can do instead of digging through the trash, such as asking for
fruits and vegetables. She has tried to stop going into the trash, but she still does it.
       She feels considerable anxiety during the day. She often feels anxious before she
hits people and before she goes into the trash. Taking her “as needed” medicine always
calms her down. If she cannot get her medications, she tries alternatives like walking,
talking to staff or listening to music.
                                          DISCUSSION
                                          I. Mootness
       Rosalinda’s one-year commitment terminated by operation of law on
November 15, 2013. Thus, her appeal is technically moot. Nevertheless, we have the
discretion to decide a moot appeal when it presents an important question of law that is
likely to evade review and is properly presented by the parties. (People v. Barrett (2012)
54 Cal.4th 1081, 1092, fn. 7 (Barrett); In re O.P. (2012) 207 Cal.App.4th 924, 927.)
Rosalinda’s equal protection challenge to the 2012 revisions of section 6500 presents
such an issue. In light of her history of serial commitment extensions, we also exercise
our discretion to review her substantial evidence claims which do not present new or
important questions of law, but tend to be recurring issues that can repeatedly evade
review. (People v. Quinn (2001) 86 Cal.App.4th 1290, 1293.)
                               II. Equal Protection of the Law
       Rosalinda argues that revisions to section 6500 made in 2012, when her
commitment was extended, deny her equal protection under the law. She is correct that
after June 27, 2012, there are some developmentally disabled persons who are committed
under section 6500 only for six months and only if they are found to be both dangerous
and in “acute crisis.” Yet, all persons who were first committed before that date remain
subject to a one-year commitment based on findings of mental retardation and
dangerousness only. As we shall explain, we accept for the purposes of Rosalinda’s
argument that the two groups are “similarly situated,” but we find a rational basis for the
statutory distinction. Before turning to our analysis, we briefly review the statutory
revisions and the extant legislative history.

                                                8
       The Statutory Revisions
       Prior to June 27, 2012, section 6500 provided that effective July 1, 1971, “no
mentally retarded person may be committed to the State Department of Developmental
Services . . . unless he or she is a danger to himself or herself, or others.” A commitment
order made pursuant to section 6500 et seq. expired automatically one year later, but
“subsequent petitions for additional periods of commitment” were permitted. Any
subsequent petitions were subject to the same procedures as the initial petition for
commitment. (Stats. 2010, ch. 178, § 102, eff. Jan. 1, 2012 to June 26, 2012.)
       In 2012, section 6500 was amended to read: “A person with a developmental
disability shall not be committed to the State Department of Developmental Services
pursuant to this article unless he or she is a person described in paragraph (2) . . . of
subdivision (a) of Section 7505 and is dangerous to self or others.” (§ 6500, subd. (b)(1),
italics added, as amended by Stats. 2012, ch. 25, § 19, eff. June 27, 2012.) The term
“developmental disability” includes mental retardation, among other conditions.
(§§ 6500, subd. (a)(2), 4512, subd. (a).)
       Section 7505 refers in subdivision (a)(2) to persons committed by a court to
Fairview Developmental Center “due to an acute crisis” as defined in section 4418.7.3
An order of commitment made with respect to a person who meets the criteria of sections
6500 and 7505, subdivision (a)(2) expires “automatically six months after the earlier of
the order of commitment pursuant to this section or the order of a placement in a
developmental center pursuant to Section 6506, unless the regional center, prior to the


       3
         Section 4418.7 provides in relevant part: “For purposes of this section, an ‘acute
crisis’ means a situation in which the consumer meets the criteria of Section 6500 and, as
a result of the consumer’s behavior, all of the following are met: [¶] (A) There is
imminent risk for substantial harm to self or others. [¶] (B) The service and support
needs of the consumer cannot be met in the community, including with supplemental
services as set forth in subparagraph (E) of paragraph (9) of subdivision (a) of Section
4648 and emergency and crisis intervention services as set forth in paragraph (10) of
subdivision (a) of Section 4648. [¶] (C) Due to serious and potentially life-threatening
conditions, the consumer requires a more restrictive environment for crisis stabilization.”
(§ 4418.7, subd. (d)(1).)
                                               9
expiration of the order of commitment, notifies the court in writing of the need for an
extension.” An extension, if granted, cannot extend the total commitment time beyond
one year. For good cause, the court may grant one further extension for up to 30 days.
(§ 6500, subd. (c)(2).)
       Section 6500 was amended again in 2012. For our purposes, it is essentially
identical to the prior version of section 6500 except it states a third category of persons
may be committed to the State Department of Developmental Services under subdivision
(b)(1): a person who “currently is a resident of a state developmental center or state-
operated community facility pursuant to an order of commitment made pursuant to this
article prior to July 1, 2012, and is being recommitted pursuant to paragraph (3) of this
subdivision.” Paragraph (3) provides: “In the event subsequent petitions are filed with
respect to a resident of a state developmental center or a state-operated community
facility committed prior to July 1, 2012, the procedures followed and criteria for
recommitment shall be the same as with the initial petition for commitment.” (§ 6500, as
amended by Stats. 2012, ch. 439, § 21, eff. Sept. 22, 2012.)4
       Legislative History
       The extant legislative history of revisions to section 6500 in 2012 makes clear that
Assembly Bill No. 1472 was introduced by the Assembly Budget Committee to deal with
“lower than anticipated revenue projections” and expected cuts of $200 million to the
2012–2013 budget for the Department of Developmental Services. Ninety-nine percent
of the consumers served by that department received community-based services while
living on the outside. Yet, approximately “1,800 individuals reside in four state-operated
DCs [state-run developmental center institutions] and one state-operated community
facility. Consistent with national trends that support integrated services and reduced
reliance on state institutions, California has been reducing its use of DCs as a placement

       4
          Effective June 27, 2013, section 6500 was amended once again to clarify that a
person with a developmental disability who is found to be a danger to herself or others
may be committed to the State Department of Developmental Services for residential
placement less restrictive than a state developmental center or state-operated community
facility. (§ 6500, subd. (b)(1)(A) & (B), as amended by Stats. 2013, ch. 25, § 11.)
                                             10
for individuals with developmental disabilities for several decades.” Among the several
“policy changes necessary to implement the projected budget reduction,” the bill included
provisions restricting admission to DCs while at the same time expanding “the
availability of adult residential facilities for persons with special health care needs to
consumers of any regional center moving from a DC.” (Sen. Rules Com., Off. of Sen.
Floor Analyses, 3d reading analysis of Assem. Bill No. 1472 (2011–2012 Reg. Sess.) as
amended June 13, 2012, pp. 1–4.)
       Assembly Bill No. 1471 recognized Assembly Bill No. 1472 created “new
restrictions on admissions to Developmental Centers.” However, the Legislature decided
the admission and recommitment criteria applicable to individuals committed before the
2012 amendments would still apply to the preamendment group. (Sen. Rules Com.,
Off. of Sen. Floor Analyses, 3d reading analysis of Assem. Bill No. 1471 (2011–2012
Reg. Sess.) as amended Aug. 24, 2012, p. 3.) The amendments in the bill were
“technical, non-substantive, and clean-up in nature.” (Assem. Budget Com., Conc. in
Sen. Amends. to Assem. Bill No. 1471 (2011–2012 Reg. Sess.) as amended Aug. 24,
2012, p. 2.)
       Equal Protection
       Our courts have often assessed an equal protection challenge in the context of a
prospective sentencing change that results in the imposition of different consequences on
particular offenders for the same conduct based on when the offense took place.
Although we recognize that treatment under a civil commitment scheme is not equivalent
to punishment for a crime, we find the analogy instructive. For example, in People v.
Floyd (2003) 31 Cal.4th 179 (Floyd), the defendant argued that the passage of
Proposition 36 created two groups of similarly situated nonviolent drug offenders—those
convicted before July 1, 2001 whose judgments were not yet final, and those convicted
after July 1, 2001—and by denying the first group access to court-supervised treatment
instead of jail, the law violated equal protection. In reviewing this argument, our
Supreme Court noted “[n]umerous courts . . . have rejected such a claim—including this
court.” (Id. at p. 188.) “A refusal to apply a statute retroactively does not violate the
                                              11
Fourteenth Amendment.” (People v. Aranda (1965) 63 Cal.2d 518, 532, superseded by
statute on another point as stated in People v. Homick (2012) 55 Cal.4th 816, 874; see
also Baker v. Superior Court (1984) 35 Cal.3d 663, 668 (Baker).) “The Legislature
properly may specify that such statutes are prospective only, to assure that penal laws
will maintain their desired deterrent effect by carrying out the original prescribed
punishment as written.” (In re Kapperman (1974) 11 Cal.3d 542, 546.) Retroactive
application of a punishment-mitigating statute is not a question of constitutional right, but
of legislative intent. (People v. Henderson (1980) 107 Cal.App.3d 475, 488.) “ ‘Nothing
. . . suggests that the equal protection clause prohibits the Legislature from creating or
abolishing a treatment program prospectively.’ ” (Floyd, supra, 31 Cal.4th at p. 191,
quoting Baker, supra, 35 Cal.3d at p. 669.)
       Therefore, the legislative decision to alter or change a sentencing scheme based on
that branch’s determination that a modification is appropriate is recognized in the above
cases along with the prerogative to set a calendar date for the commencement of that
“new” scheme. It has happened with the passage of Proposition 36, as well as the recent
2011 Public Safety Realignment Act (Realignment Act). (People v. Lynch (2012) 209
Cal.App.4th 353, 359 (Lynch).) It seems equally reasonable to accept this legal principle
when considering civil commitment schemes such as Welfare and Institutions Code
section 6500 et seq. (See Baker, supra, 35 Cal.3d at pp. 668–669 [prospective repeal of
the mentally disordered sex offender (MDSO) law is constitutional].) “ ‘[T]he
Fourteenth Amendment does not forbid statutes or statutory changes to have a beginning
and thus to discriminate between the rights of an earlier and later time.’ ” (Baker, supra,
35 Cal.3d at p. 669, quoting Sperry & Hutchinson Co. v. Rhodes (1911) 220 U.S. 502,
505; see also Lynch, supra, 209 Cal.App.4th at p. 359 [prospective application of
Realignment Act is constitutional].)
       We assume for the sake of Rosalinda’s argument that individuals subject to
commitment under section 6500, on either side of the July 1, 2012 divide, are similarly
situated to each other for the purpose of the law, which, as we see it, is to isolate for
public safety reasons and to treat humanely and cost-effectively those developmentally

                                              12
disabled persons who are dangerous to themselves or others. (Conservatorship of
Hofferber (1980) 28 Cal.3d 161, 172, citing Baxstrom v. Herold (1966) 383 U.S. 107,
111; In re Gary W. (1971) 5 Cal.3d 296, 304.)
       Statutory classifications that treat similarly situated mentally retarded persons
differently with respect to issues affecting their civil commitments are evaluated using
rational basis review. (Barrett, supra, 54 Cal.4th at p. 1111, fn. 21; Heller v. Doe (1993)
509 U.S. 312, 319–321 (Heller).) In Heller, the United States Supreme Court used
rational basis review to uphold Kentucky’s use of a clear and convincing standard of
proof to commit the mentally retarded and a reasonable doubt standard of proof to
commit the mentally ill. Under rational basis review, “a classification ‘must be upheld
against equal protection challenge if there is any reasonably conceivable state of facts
that could provide a rational basis for the classification.’ [Citations.] [¶] A State,
moreover, has no obligation to produce evidence to sustain the rationality of a statutory
classification. ‘[A] legislative choice is not subject to courtroom factfinding and may be
based on rational speculation unsupported by evidence or empirical data.’ [Citations.] A
statute is presumed constitutional . . . and ‘[t]he burden is on the one attacking the
legislative arrangement to negative every conceivable basis which might support it,’
[citation] whether or not the basis has a foundation in the record.” (Heller, supra, 509
U.S. at pp. 319–321.)
       In view of the principles discussed above, and applying rational basis review to the
issue before us, we have no difficulty finding constitutional the new statutory scheme
envisioned by the prospective 2012 revisions to section 6500. The legislative prerogative
to change the law prospectively is no different with respect to experimental treatment
protocols than with experimental sentencing schemes. “Equal protection considerations
will not preclude the legislative branch from prescribing experimental programs.”
(McGlothlen v. Department of Motor Vehicles (1977) 71 Cal.App.3d 1005, 1021.) The
Legislature has a rational interest in “limiting the potential costs of its experiment,” and
prospective application is reasonably related to this goal. (Lynch, supra, 209 Cal.App.4th
at p. 361.)

                                              13
       The changes to the criteria for and duration of commitments under section 6500
are no less significant a legislative experiment than the prospective application of the
Realignment Act upheld in Lynch or the prospective repeal of the MDSO laws upheld in
Baker, supra, 35 Cal.3d 663. As the extant legislative history of section 6500 and its
companion statutes (e.g., §§ 7505, 4418.7) make clear, the Legislature has concluded that
more cost-effective ways must be found to isolate, yet humanely treat, developmentally
disabled persons who pose a danger to themselves or others. Going forward, it has
determined to invest in community-based placement and services over regional center-
based placements for the treatment and isolation of the dangerous developmentally
disabled.
       In our view, Baker presents a close analogue to this case and assists our analysis.
In Baker, our Supreme Court found “[n]o significant constitutional problem [] presented
by the prospective repeal of the MDSO laws. . . . [¶] Legislation almost inevitably
creates some disparities and the differential results which follow the termination of the
MDSO program appear no different than those which inevitably accompany either the
establishment or elimination of any statutory treatment program. . . . [¶] [T]he
Legislature decided in 1981 that the MDSO program was not sufficiently successful to
warrant continuation; it therefore provided that no one convicted after the enactment
became effective should be committed to the MDSO program. As to those persons ‘other
enactments . . . would yield prison terms which would provide . . . protection to
society. . . .’ (Stats. 1981, ch. 928, § 3.) [Fn. omitted.] At the same time, the Legislature
decided that the program should not be ended for those persons already committed as
MDSO’s, apparently concluding that it would be inimical to the public safety simply to
end the program altogether, resulting in the release of many still dangerous persons.
[¶] When the Legislature eliminated the MDSO program, petitioners had already been
committed and were serving their initial term imposed pursuant to section 6316.1; they
all faced the possibility of an extension if, at the end of the maximum term prescribed for
the sex offense, they met the criteria of section 6316.2. The repeal of the MDSO law did
not affect the commitment which had been imposed in lieu of criminal sanctions; the

                                             14
commitment did not become more onerous than it had been. Petitioners were and still are
entitled to release when no longer dangerous regardless of the period of confinement for
the analogous prison term now specified for the offenses. Stripped to its essentials,
petitioners’ claim challenges the basic validity of all prospective lawmaking.” (Baker,
supra, 35 Cal.3d at pp. 668–670.)
       Likewise, in this case, the legislative decision to implement prospectively
community-based treatment programs for dangerous developmentally disabled persons
has inevitably created some disparities between prior committees and new ones. As with
the former MDSO committees, the Legislature has decided to proceed cautiously with
respect to the release of developmentally disabled persons who have already been
adjudicated to be dangerous to themselves or others and judicially placed in regional
center facilities. That decision is neither irrational nor unconstitutional. “[A]n equal
protection violation does not occur merely because different statutory procedures have
been included in different civil commitment schemes. [Citation.] Nothing compels the
state ‘to choose between attacking every aspect of a problem or not attacking the problem
at all.’ [Citation.] Far from having to ‘solve all related ills at once’ [citation], the
Legislature has ‘broad discretion’ to proceed in an incremental and uneven manner
without necessarily engaging in arbitrary and unlawful discrimination.” (Barrett, supra,
54 Cal.4th at p. 1110.) We hold no equal protection violation has occurred here.
                                 III. Substantial Evidence
       Rosalinda attacks the order recommitting her to CPT as lacking substantial
evidence that (1) mental retardation is the cause of her serious difficulty controlling
dangerous behavior, and (2) a locked facility is the least restrictive appropriate
placement. For the reasons stated below, we conclude substantial evidence supports the
court’s order.
       In reviewing the sufficiency of the evidence to support an involuntary
commitment under Welfare and Institutions Code section 6500, we apply the same
standard we use to review the sufficiency of the evidence to support a criminal conviction
and other types of involuntary commitments. (People v. Mercer (1999) 70 Cal.App.4th

                                               15
463, 466.) “Under this standard, the court ‘must review the whole record in the light
most favorable to the judgment below to determine whether it discloses substantial
evidence—that is, evidence which is reasonable, credible, and of solid value—such that a
reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.’
[Citations.] The focus of the substantial evidence test is on the whole record of evidence
presented to the trier of fact, rather than on ‘ “isolated bits of evidence.” ’ ” (People v.
Cuevas (1995) 12 Cal.4th 252, 260–261, italics omitted.) We, therefore, view the
evidence in the light most favorable to the judgment and presume in support of the
judgment the existence of every fact the trier could reasonably deduce from the evidence.
(People v. Johnson (1980) 26 Cal.3d 557, 576–577.)
       A. Dangerousness Finding
       Rosalinda first asserts that the evidence is lacking because Dr. Turpin “did not
explain the nature of the mental retardation and why it made [her] unable to control
dangerous behavior.” Further, “[h]e was unable to say whether it was the mental
retardation or the schizophrenia that caused the behavior.” And finally, Rosalinda argues
that while there was evidence she did not control her behavior, there was no evidence that
she “tried to control [her] behavior, that [she] encountered serious difficulty when trying
to do so, or that [her] difficulty was caused by [her] mental condition.” (People v.
Galindo (2006) 142 Cal.App.4th 531, 539.) We disagree.
       To be sufficient, the evidence need not demonstrate that mental retardation caused
the dangerous behavior. (People v. Quinn, supra, 86 Cal.App.4th at p. 1293.) On the
other hand, it must support a finding by the trier of fact that mental retardation was a
substantial factor in causing her serious difficulty in controlling her dangerous behavior.
(People v. Cuevas (2013) 213 Cal.App.4th 94, 97 (Cuevas); In re O.P., supra, 207
Cal.App.4th at pp. 930–931; People v. Sweeney (2009) 175 Cal.App.4th 210, 225.)




                                              16
       Here, expert testimony on Rosalinda’s specific IQ score or mental age5 was not
necessary to support the requisite finding because the parties did not dispute the diagnosis
of mild mental retardation. Dr. Turpin explained that in general, mentally retarded
people tend to exhibit immature coping skills, poor impulse control, and difficulty
managing their behavior. Rosalinda’s presentation was consistent with her long-standing
history of mild mental retardation, and she exhibited the immaturity of coping skills, poor
impulse control, and difficulty managing her behavior characteristic of a person with
mental retardation. Specifically, Dr. Turpin testified that in his opinion, Rosalinda was a
danger to others “because of the repetitive hitting at other people, pushing people,” and
that Rosalinda had serious difficulty controlling that behavior because of her mental
retardation.
       The situation in Cuevas, supra, 213 Cal.App.4th 94 is factually distinguishable
from Rosalinda’s situation here. In Cuevas, “the evidence introduced at trial strongly
suggested that Ronald’s dangerous behavior was attributable almost entirely to his mental
illness (i.e., psychosis), and not his mental retardation.” (Id. at p. 107.) That simply is
not the case here. Dr. Turpin concluded that Rosalinda’s lack of self-control was more
attributable to her mental retardation than her mental illness because he had “not
observed symptoms of schizophrenia, the auditory delusion or disorganized thinking, so
it seems more consistent with poor impulse control associated with her mental
retardation.” His opinion in this regard was supported by his extensive testimony about
his observations of Rosalinda since 2011, his efforts to ameliorate her aggressive and
ritualistic behaviors by increasing the dosages of her antipsychotic medications, and the
apparent failure of those efforts to help Rosalinda control those behaviors after a brief
respite from them in February 2013. Furthermore, he testified that at one time, Rosalinda

       5
         “The AAMR [American Association on Mental Retardation] guidelines specify
four different degrees of mental retardation, from mild to profound. According to that
classification system, an adult with an IQ between 50 and 70 is deemed to have ‘mild’
mental retardation. [Citations.] . . . Mild mental retardation in adults is equivalent to a
‘mental age from 9 to under 12 years.’ [Citation.]” (Barrett, supra, 54 Cal.4th at
pp. 1114, 1130 (conc. & dis. opn. of Liu, J.).)
                                             17
had attributed her behavior to “voices telling her to do that,” but that she no longer did so.
In short, even though Dr. Turpin had “not observed symptoms of schizophrenia,”
Rosalinda continued to engage in aggressive behavior, although she could not explain to
him what motivated her to do so. In our view, Dr. Turpin’s testimony provided sufficient
basis for the court to confidently conclude that Rosalinda’s mental retardation was a
substantial factor in causing her serious difficulty controlling her dangerous behavior, and
that her dangerous behavior was not attributable solely to her mental illness.
       Additionally, the record supports the conclusion that Rosalinda’s conduct was not
“volitional.” In addition to Dr. Turpin’s expert testimony that Rosalinda had difficulty
managing her aggressive behavior, Rosalinda’s own testimony demonstrated that she had
great difficulty controlling herself. For example, she admitted that lately she had been
trying to stop herself from hitting and sometimes succeeded, but she still hit people.
Similarly, she knew she could eat more fruits and vegetables instead of digging in the
trash for food, and she had tried to stop going into the trash can, but she still did it. The
evidence was sufficient in this regard.
       Finally, in our view, the evidence indicating that Rosalinda threw chairs and hit
both peers and staff was sufficient to support a finding that Rosalinda posed a danger to
public health and safety. To be sufficient in this regard, the evidence must show the
person’s conduct has “the potential for infliction of substantial harm upon [herself] or
upon others.” (People v. Alvas (1990) 221 Cal.App.3d 1459, 1467, disapproved on other
grounds in Barrett, supra, 54 Cal.4th at p. 1106; see also People v. Hartshorn (2012) 202
Cal.App.4th 1145, 1154 [conduct presents a likelihood of serious physical injury to self
or others].) Although her behavior had not yet caused any injury, the trial court was
entitled to infer from the evidence there was a very real likelihood or potential that if
unchecked Rosalinda’s assaultive behavior would eventually result in physical injury to
herself or others and, therefore, posed a danger to public safety.
       B. Least Restrictive Appropriate Placement
       Welfare and Institutions Code section 6506 provides in relevant part: “Prior to the
issuance of an order under this section, the regional center and developmental center, if
                                              18
applicable, shall recommend to the court a suitable person or facility to care for the
person alleged to have a developmental disability. The determination of a suitable person
or facility shall be the least restrictive option that provides for the person’s treatment
needs and that has existing security systems or measures in place to adequately protect
the public safety from any known dangers posed by the person.” (Italics added.) “There
is a [statutory] preference for the least restrictive environment provided that ‘public
safety’ will not be compromised.” (People v. Quinn, supra, 86 Cal.App.4th at p. 1295.)
       Rosalinda argues the evidence is insufficient to support a finding that CPT, a
locked facility, is the least restrictive placement option for her. She further argues, “[t]he
evidence as to placement comes entirely from Jeffrey Nagafuji,” and she takes issue with
Mr. Nagafuji’s testimony because he is not an expert and has no licenses. She claims his
testimony was conclusory and lacked particulars. She alleges he rejected board-and-care
home placement “not necessarily because it would not be appropriate, but merely because
there were no vacancies at present.”6 We disagree.
       Mr. Nagafuji testified as the case management supervisor at the Regional Center.
As such, he was in charge of the Regional Center team tasked with finding the most
appropriate placement for Rosalinda, given her particular mental health and behavioral
needs. He did not need to be an expert, or possess any particular licenses, to testify about
his efforts or his team’s efforts to find Rosalinda an appropriate placement. He knew that


       6
         Rosalinda also complains that Mr. Nagafuji’s report was full of hearsay about her
aggressive behavior and should not have been admitted into evidence over objection.
Inasmuch as we have not considered the contents of the report in connection with
Rosalinda’s evidentiary insufficiency arguments, we decline to rule on its admissibility.
However, “where a section 6500 petition is filed, the trial court is entitled to a written
report prepared by, or at the behest of, the director of the regional center, following an
examination of the alleged mentally retarded person. (§ 6504.5.) Regional centers
specialize in assessing and assisting mentally retarded and other developmentally
disabled persons on an individual basis. [Citation.] Thus, the regional center report
obviously serves as a professional pretrial evaluation of the person’s history, condition,
and behavior, and includes informed recommendations on treatment and placement,
including any interim placement pending the hearing.” (Barrett, supra, 54 Cal.4th at
p. 1104.)
                                              19
prior to her placement at CPT, Rosalinda had lived at home and in a number of care home
facilities. These placements did not work out. The existing supports were not meeting
her mental health and behavioral needs; a higher level of care was indicated. At the latest
quarterly review of Rosalinda’s placement at CPT in August 2012, Nagafuji and his team
considered placement options other than CPT, either in her mother’s home or at a board-
and-care home. He determined that such placements were not appropriate at that time
because Rosalinda still required close mental health monitoring and ready access to on-
site mental health professionals or psychiatrists. She also needed to be in a place that
could deal with her aggressive behavior, and there were no unlocked facilities currently
available that could meet Rosalinda’s needs as well as CPT was meeting them. However,
he did not rule out transitioning Rosalinda to a board-and-care or group home in the
future if she were able to display stability for a long enough period of time.
       We do not view Mr. Nagafuji’s testimony as a statement that board-and-care
homes were rejected as an appropriate placement because of lack of availability.
Moreover, he was not the only witness whose testimony bore on the appropriateness of
Rosalinda’s placement at CPT, nor do we view his testimony in isolation. Dr. Turpin’s
testimony filled in the picture about Rosalinda’s behavioral difficulties, and the necessity
of moving her to the more restrictive Disruptive Behavioral Unit within CPT in order to
deal with them. Rosalinda’s mother’s testimony shed light on the problems Rosalinda
had previously encountered at home and in board-and-care homes, and on the type of
care she would get if she were returned home. Rosalinda’s mother also attested to the
improvements in Rosalinda’s behavior and outlook while at CPT. Taken together, the
evidence was sufficient to establish that CPT was the least restrictive appropriate
placement for Rosalinda.
                                      DISPOSITION


       The judgment is affirmed.
