INTRODUCTION

A jury found Larry Allen Jackson to be a sexually violent predator (SVP) 

under the Sexually Violent Predator Act, Welfare and Institutions Code section 6600 et 

seq. (SVPA).1

 The trial court ordered him committed to the California Department of 

State Hospitals (DSH) for an indeterminate term.

Jackson argues the trial court prejudicially erred by granting the 

prosecution’s motion to exclude Jackson’s only SVP expert witness from testifying at 

trial. We agree and therefore reverse and remand to the trial court for a new SVP trial.

Based on the record before us, and applying California Supreme Court 

authority, we hold that in the context of SVP cases, in determining whether to exclude 

defense expert witness testimony, the trial court must consider both applicable statutory 

law, including relevant portions of the SVPA and the Civil Discovery Act of 2004 (Code 

Civ. Proc., § 2016.010 et seq.) (Civil Discovery Act) and the defendant’s constitutional 

due process right to present such evidence. Here, the trial court’s exclusion of critical 

defense expert testimony to rebut the testimony of the prosecution’s two expert witnesses 

deprived Jackson of a fair trial.

GENERAL OVERVIEW OF THE SVPA AND ITS INTERPLAY WITH THE 

CIVIL DISCOVERY ACT AND DUE PROCESS

The SVPA authorizes the indefinite involuntary civil commitment of 

persons found to be sexually violent predators after they conclude their prison terms. 

(Reilly v. Superior Court (2013) 57 Cal.4th 641, 646-647; People v. McKee (2010) 47 

Cal.4th 1172, 1186-1187.) At trial on a commitment petition under the SVPA, the 

prosecution must prove three elements beyond a reasonable doubt: (1) the person has 

suffered a conviction of at least one qualifying “sexually violent offense”; (2) the person 

1 All statutory references are to the Welfare and Institutions Code unless otherwise 

specified.
3

has “a diagnosed mental disorder that makes the person a danger to the health and safety 

of others”; and (3) the mental disorder makes it likely the person will engage in future 

predatory acts of sexually violent criminal behavior if released from custody. (§ 6600; 

see §§ 6603, 6604; People v. Shazier (2014) 60 Cal.4th 109, 126; People v. Yates (2018) 

25 Cal.App.5th 474, 477.)

The prosecution, therefore, must carry the burden of proving beyond a 

reasonable doubt “that because of a diagnosed mental disorder affecting the person’s 

volitional or emotional control, ‘“it is likely that he or she will engage in sexually violent 

behavior” if released.’ [Citations.] ‘Likely,’ in this context, does not mean more likely 

than not; instead, the standard of likelihood is met ‘when “the person presents a 

substantial danger, that is, a serious and well-founded risk, that he or she will commit 

such crimes if free in the community.”’” (People v. Shazier, supra, 60 Cal.4th at p. 126, 

italics omitted.)

A “‘[d]iagnosed mental disorder’ includes 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).) “Expert testimony, specifically 

testimony regarding diagnosis of a current mental disorder, is an important element in an 

SVPA civil commitment proceeding.” (People v. Roa (2017) 11 Cal.App.5th 428, 443.) 

As our Supreme Court has explained in this context: “[E]xpert testimony is 

critical” because “the primary issue is not, as in a criminal trial, whether the individual 

committed certain acts, but rather involves a prediction about the individual’s future 

behavior.” (People v. McKee, supra, 47 Cal.4th at p. 1192.) 

SVPA trials constitute special proceedings of a civil nature (Moore v. 

Superior Court (2010) 50 Cal.4th 802, 815), and the Civil Discovery Act applies (People 

v. Landau (2013) 214 Cal.App.4th 1, 25). Under the Civil Discovery Act, a party is 

permitted to retain and designate “expert trial witnesses.” (Code Civ. Proc., §§ 2034.210-
4

2034.290). Section 6603, subdivision (a) of the SVPA authorizes expert witness 

discovery, and provides that “a person subject to commitment under the [SVPA]

has . . . a right to retain experts or professionals to perform examinations on his or her 

behalf—and . . . also has a right to present the resulting evidence to the jury.” (Albertson 

v. Superior Court (2001) 25 Cal.4th 796, 803, italics added; see also People v. Superior 

Court (Smith) (2018) 6 Cal.5th 457, 463.) 

A defendant in an SVP proceeding is entitled to due process protections

because civil commitment involves a significant restraint on liberty. (Moore v. Superior 

Court, supra, 50 Cal.4th at p. 818; see People v. Force (2019) 39 Cal.App.5th 506, 514

[the defendant in SVP proceedings “has a constitutional right to present a defense, which 

includes calling witnesses in his favor and testifying on his own behalf”].) As explained 

by a panel of this court in People v. Landau, supra, 214 Cal.App.4th at pages 27-28: 

“‘[C]ivil commitment for any purpose constitutes a significant deprivation of liberty that 

requires due process protection. [Citations.]’ [Citation.] The ‘most elemental of liberty 

interests’ protected by the due process clause is ‘the interest in being free from physical 

detention by one’s own government. [Citations.]’ [Citation.] ‘Freedom from bodily 

restraint has always been at the core of the liberty protected by the Due Process Clause 

from arbitrary governmental action.’” In People v. Otto (2001) 26 Cal.4th 200, 210 

(Otto), the California Supreme Court identified and applied factors that determine the 

extent of process due to such a defendant.

If the jury unanimously finds the defendant to be an SVP, then the 

defendant is committed for an indeterminate term to the custody of the DSH. (§ 6604.)

Following commitment, the SVP is subject to annual mental examinations to determine 

whether he or she continues to meet the definition of an SVP. (§ 6604.9, subds. (a) & 

(b).)

FACTS AND PROCEDURAL HISTORY

I.

DEFENSE EXPERT PREPARES REPORT FOLLOWING EVALUATION OF JACKSON, AND 

JACKSON SERVES DESIGNATION OF EXPERT WITNESS.

In June 2007, the Orange County District Attorney filed a fourth petition 

under the SVPA to commit Jackson as an SVP, which is the operative pleading in this 

matter. After extensive litigation not relevant to the issue presented in this appeal, trial 

was set for November 2019. In anticipation of trial, defense expert Dr. Christopher J. 

Fisher prepared a report in accordance with section 6600 et seq. following the completion 

of his psychological evaluation of Jackson (the September 2019 report). In his report, Dr. 

Fisher concluded that Jackson did not qualify as an SVP because he did not “have a 

diagnosed mental disorder that predisposed him to the commission of criminal acts” and 

was unlikely “to engage in sexually violent predatory criminal behavior as a result of his 

diagnosed mental disorder without appropriate treatment and custody.”

In December 2019, trial was continued to February 18, 2020. In 

anticipation of trial, in early January, the parties exchanged expert witness designations. 

The prosecution designated Dr. Douglas Korpi and Dr. Robert Owen as positive state 

SVP evaluators. Jackson served a notice designating only Dr. Fisher as the defense SVP 

expert witness, stating Dr. Fisher “will testify regarding his evaluation of Mr. Jackson 

and discuss areas including, but not limited to, diagnosis, risk to reoffend, volitional 

control, whether Mr. Jackson can be safely treated in an outpatient setting, whether he 

meets the criteria as a Sexually Violent Predator, recidivism, and more.” 

The following week, the prosecution served a subpoena and notice of

taking Dr. Fisher’s deposition and a request for the production of documents. 
6

II.

TRIAL IS CONTINUED TO JULY; JACKSON RE-SERVES HIS EXPERT WITNESS 

DESIGNATION.

At the end of January, the prosecution filed its first motion to continue the 

jury trial on the ground one of the prosecution’s two expert witnesses, Dr. Korpi, had 

informed the prosecution that his opinion that Jackson is an SVP had changed from 

positive to negative. The prosecution also requested that the trial court order Dr. Korpi to 

conduct an updated evaluation. The trial court granted the prosecution’s motion, ordered 

Dr. Korpi to complete an updated evaluation, continued trial until July 13, 2020, and 

“reset all discovery timelines.” On January 31, the prosecution cancelled Dr. Fisher’s 

deposition as noticed. 

In May 2020, Jackson re-served his expert witness designation and 

declaration identifying Dr. Fisher as his sole expert witness. 

III.

IN JUNE 2020, THE PROSECUTION INFORMS THE TRIAL COURT OF DELAYS 

REGARDING ITS SECOND EXPERT WITNESS.

At a pretrial hearing on June 5, 2020, the prosecution informed the trial 

court that Dr. Korpi had conducted an updated SVP evaluation of Jackson in March and 

thereafter confirmed his original positive opinion that Jackson qualified as an SVP. The 

prosecution also advised the trial court, however, that the prosecution’s other SVP expert 

(Dr. Owen) had retired in May, resulting in the designation of a replacement evaluator. 

The replacement evaluator, however, had recently declared a conflict in the case. The 

prosecution’s request for another replacement SVP evaluator was pending. The 

prosecution advised the trial court that, as a result of these developments, it did not 

appear likely the prosecution would be ready for trial as scheduled on July 13. 

The trial court did not continue trial at that time, but acknowledged the 

prosecution’s challenges and informed the parties “‘you will not go out the 13th. You 
7

might go out a couple months of that’” and that “‘at the end of the day it is going to be 

delayed for every single case,’ due to the COVID-19 Global Pandemic.” 

IV.

THE TRIAL COURT GRANTS THE PROSECUTION’S SECOND MOTION TO CONTINUE 

TRIAL AND RESETS DISCOVERY AGAIN.

The following week, the prosecution filed its second motion to continue the 

trial. This time, it was brought on the ground that the prosecution needed time to obtain 

subpoenaed “necessary and essential records” that the new evaluator for the prosecution, 

Dr. Craig King, had reviewed in his evaluation of Jackson. At the hearing on the motion, 

the trial court stated it was inclined to grant a brief continuance of the trial given the 

prosecution’s entitlement to the subpoenaed records and the possibility Jackson would 

want to depose Dr. King. 

Over Jackson’s objection, the trial court continued trial to August 3, 

warning the parties: “[Y]ou should get your witnesses lined up. You will be going.” 

The trial court and counsel thereafter engaged in the following discussion:

“[The prosecutor]: I’m going to do that as soon as I’m done here, your 

Honor. I am going to ask the court to reset discovery, also, so that I can include Dr. King 

in the People’s—

“The Court: So reset.

“[A]re you going to waive any discovery time line issues so you can get 

everything as quickly as possible? Otherwise, it’s supposed to be a 90-day time line, and 

we’re well within that.

“[Defense counsel]: Well, it’s—yes. 

“The Court: You understand what I’m saying?

“[Defense counsel]: I do.
8

“The Court: We can go and splice that into each one of the pieces and 

parcels as to what that turns into, but at this point if you just waive them generically, we 

can get to the point where you can share everything and get this done.

“[Defense counsel]: Yes, within reason.

“The Court: Of course. If something changes, come and bring it to me.” 

V.

THE PROSECUTION SERVES A DEMAND FOR EXCHANGE OF EXPERT WITNESS 

INFORMATION AND AN EXPERT WITNESS DESIGNATION AND DECLARATION.

On July 14, 2020, the prosecution served a demand for exchange of expert 

information, requesting the mutual exchange of expert information on August 3 (the date 

then set for trial). On July 31, the prosecution served its “Exchange of Expert 

Information,” identifying Dr. Korpi and Dr. King as the expert witnesses the prosecution

intended to call at trial. 

VI.

AFTER JACKSON DOES NOT RE-SERVE HIS EXPERT WITNESS DESIGNATION BUT 

INCLUDES DR. FISHER ON HIS WITNESS LIST, THE PROSECUTION MOVES IN LIMINE

TO HAVE DR. FISHER EXCLUDED FROM TESTIFYING AT TRIAL.

Jackson did not re-serve his expert witness designation and declaration by 

August 3. Instead, three days later, he served his witness list, which included Dr. Fisher. 

In response, the prosecution filed a motion in limine seeking to exclude Dr. Fisher from 

testifying at trial. The prosecution argued exclusion was the only remedy under Code of 

Civil Procedure section 2034.300 to address Jackson’s failure to comply with the expert 

exchange requirement. 

At the hearing on the motion, the trial court confirmed that Jackson had 

already served expert witness declarations designating Dr. Fisher twice, first in January 

and again in May. The prosecutor informed the trial court that if Dr. Fisher was not 

excluded, he wanted to depose Dr. Fisher and wanted to do so before the jury was 
9

selected. The prosecutor said Dr. Fisher’s testimony could affect how the prosecution

would conduct voir dire and present its case-in-chief. 

The trial court deferred ruling on the motion in limine pending the parties’ 

success in deposing Dr. Fisher during scheduled days off from trial later that month. The 

trial court opted to move ahead with jury selection and opening statements before Dr. 

Fisher’s deposition could be taken.

2

 

The prosecutor asked if there was any additional information that defense 

counsel needed to provide to the prosecution; defense counsel indicated there was none. 

The prosecutor confirmed with defense counsel that the September 2019 report was the 

only report Dr. Fisher had produced and that the information stated in that report was still 

what Dr. Fisher was going to rely on and testify to at trial. 

After defense counsel later confirmed that Dr. Fisher would be available to 

sit for a remote deposition on August 26, 2020, the prosecution served a subpoena and 

notice of Dr. Fisher’s deposition. They included a demand that Dr. Fisher produce 

written notes, documents, and/or recordings that he prepared in relation to or pertaining 

to his interview of Jackson. 

VII.

THE PROSECUTION’S CASE-IN-CHIEF

3

From August 11, 2020 through August 24, 2020, a jury was selected and 

the prosecution presented most of its case-in-chief by calling as witnesses five victims of 

Jackson’s molestations, a retired investigator, and the prosecution’s two expert witnesses. 

2 The prosecution confirmed that Dr. Korpi would be available to testify on rebuttal after 

Dr. Fisher testified at trial. 

3

 The trial evidence of Jackson’s prior sex offenses is not at issue in this appeal. This 

section contains a brief summary of the facts for the purpose of providing general 

background. 
10

The evidence presented showed that in the late 1970’s, Jackson lived with 

his brother, his brother’s wife, and his brother’s three young stepdaughters who were all 

under the age of 10 years. On several occasions, Jackson sexually molested the young 

girls. In 1979, Jackson pleaded guilty to one count of annoying or molesting children in 

violation of former Penal Code section 647a against the oldest child, T., and was 

sentenced to three years’ probation. 

In the mid-1980’s, Jackson lived with a mother, her two sons, and her 

three-year-old daughter B.; Jackson molested B. over the course of two years. In August 

1984, Jackson molested a five-year-old girl who had visited the family with her mother. 

In 1988, Jackson pleaded guilty to two counts of violating Penal Code section 288, 

subdivision (a) (lewd and lascivious acts with a child under the age of 14) against B. and 

was sentenced to 10 years in prison. 

In January 1994, Jackson was invited to move in with a friend who had a 

four-year-old daughter. Jackson molested that child, too. In that case, Jackson pleaded 

guilty to one count of committing a lewd and lascivious act against a child under 14 years 

of age in violation of Penal Code section 288, subdivision (a), and was sentenced to three 

years in prison. 

Jackson suffered probation and parole violations. 

The prosecution also offered Dr. King’s and Dr. Korpi’s expert witness 

testimony that then 67-year-old Jackson met all the criteria for qualifying as an SVP. 

VIII.

ON THE EVE OF DR. FISHER’S DEPOSITION, DEFENSE COUNSEL DISCLOSES 

DR. FISHER HAD MET WITH JACKSON IN FEBRUARY 2020; DR. FISHER 

PRODUCES NOTES FROM THAT MEETING.

The prosecution had almost completed its case-in-chief at the time of Dr. 

Fisher’s deposition. The afternoon before that deposition, defense counsel sent an email 

to the prosecutor stating the following:
11

“Hello [the prosecutor],

“I talked with Dr. Fisher briefly and he let me know that he saw Mr. 

Jackson on February 20, 2020 for a short period of time to discuss his offenses. He 

admitted to the two qualifying and T[.] There is no other information: He did not write 

an addendum and was not paid to see him the second time. I guess he was seeing other 

patients at CSH.

“Thanks,

“[Defense counsel].” 

On August 26, 2020, the prosecutor began the remote deposition of Dr.

Fisher during which the prosecutor concluded that many of the representations made by

defense counsel in her email were contradicted by Dr. Fisher’s testimony. Among other 

things, Dr. Fisher said he had pages of notes relating to his February 2020 interview of 

Jackson and the interview was conducted in part at defense counsel’s direction. 

At the deposition, Dr. Fisher testified:

“Q. When did you relay to [defense counsel] that you had spoken with Mr. 

Jackson again?

“A. I know we discussed it yesterday. I don’t recall if I had told her—I 

know we discussed previously, like in January or February, about the idea of me

interviewing him again, and then I did go and interview him again on February 20th of 

this year.

“I don’t recall when I would have relayed that information to [defense 

counsel] or if I ever explicitly did. I think I probably did, actually, but I couldn’t tell you 

when. I don’t know.

“Q. Do you normally write a report and then do a follow-up interview and 

not relay the fact that you interviewed someone to the attorney who retained you? 

“[¶] . . . [¶]

“A. No. That would not be my normal process.” 
12

The prosecutor asked Dr. Fisher why he met with Jackson to discuss 

offenses Jackson had already denied committing. Dr. Fisher testified: “So I was already 

at Coalinga State Hospital that week seeing a number of other patients, and [defense 

counsel] and I had communicated about my initial interview with him and the report that 

I had already written at that point, and we had discussed his denial of his offenses to me, 

and then [defense counsel] let me know that she felt like his explanation of his offenses 

might have evolved and changed over the—what was it—five months or so since I had 

last seen him or six months. [¶] And so that’s why I set up another interview with him, 

and it—initially, the motivation was just to discuss his offenses. The interview took a 

couple of other turns as well, and we didn’t only discuss his offenses, although that was 

the primary motivation at the beginning.” 

Dr. Fisher thus confirmed he met with Jackson at defense counsel’s 

prompting and that he met with Jackson for an hour and took notes that had not been 

produced even to defense counsel. He did not write a report after that meeting. Dr. 

Fisher stated that, within a few weeks or a month after the interview, he had informed 

defense counsel of it. Dr. Fisher testified he assumed this information would come out 

during his deposition and at trial. He added that nothing in those interviews changed his 

ultimate opinions as outlined in the September 2019 report, and that if anything, they

only “kind of strengthened my opinions.” 

The prosecutor stated he felt he was at a disadvantage, having received the 

information about the February 2020 interview on the day of the deposition. Dr. Fisher 

sent the prosecutor “about two pages worth” of handwritten notes that he had taken

regarding the February 2020 interview. Dr. Fisher confirmed he had not yet billed for the 

hour-long interview in February 2020, but that he intended to do so.

The prosecutor proceeded to depose Dr. Fisher on his opinions on the SVP 

criteria as they applied to Jackson. Dr. Fisher testified that Jackson’s age (67 years) is a 

protective factor and “the most mitigating factor.” He testified that a diagnosis of 
13

pedophilic disorder is not automatically a permanent diagnosis. Dr. Fisher stated that in 

the 1970’s through the 1990’s, Jackson likely met the criteria for the diagnosis, but that 

he did not believe he met the criteria in 2020.4

 

After three hours, the prosecutor stopped the deposition. He stated he had 

only budgeted three hours for it and had defense counsel given him the information about 

the February 2020 interview, he could have been prepared instead of spending one of the 

three hours sorting out what had happened. It is unclear whether the prosecutor had any 

further questions for Dr. Fisher before concluding the deposition.

IX.

THE TRIAL COURT GRANTS THE PROSECUTION’S MOTION SEEKING TO EXCLUDE DR.

FISHER’S TESTIMONY AT TRIAL.

On August 31, 2020, the prosecution filed another motion to exclude Dr. 

Fisher from testifying. This time, the prosecution sought exclusion of Dr. Fisher’s expert 

testimony at trial because Jackson had “fail[ed] to participate in a properly demanded 

Expert Exchange” and had “intentionally mispresent[ed] discovery compliance regarding 

properly demanded discovery pursuant to a deposition subpoena after the court 

determined [the People] would be afforded the opportunity to depose [Jackson’s]

undeclared expert witness after the jury trial had begun and after [the People] had 

effectively completed putting on [its] case-in-chief.” 

At the hearing, defense counsel opposed the prosecution’s motion by

arguing: 

4

 Dr. Fisher further testified at his deposition that “there aren’t any studies, not a single 

one, that point to men of the age of 67 or older as serious and well-founded recidivism 

risk[s] even if they have multiple prior sex offenses.” He clarified that it is not 

impossible for men of older age to reoffend, but with age, that risk becomes highly 

unlikely, particularly because Jackson’s last offense occurred in 1994. Dr. Fisher also 

clarified that his opinion was not premised on the notion Jackson had not committed the 

sex offenses and that he had not taken Jackson at his word when, in September 2019, he 

denied committing those offenses.
14

• Defense counsel had already disclosed Dr. Fisher as the defense

expert witness after the initial trial setting and the “whole purpose” of the most recent 

exchange of expert witness information was to enable the prosecution to designate 

newly assigned evaluator Dr. King as an expert for the prosecution; 

• The prosecution’s notice of deposition itself did not require 

production of requested documents three days before Dr. Fisher’s deposition; 

• Dr. Fisher produced the requested documents at the deposition in 

compliance with the notice; 

• Defense counsel thought she had sent the prosecutor an email 

informing him of Dr. Fisher’s February 2020 meeting with Jackson, but when she could 

not find such an email, she disclosed that information, admittedly later than she should 

have;

5

• Although she did not plan to ask Dr. Fisher at trial about Jackson’s 

admission of the sex offenses, she recognized that that information might be relevant for 

cross-examination, but then believed the issue had become “moot” in March 2020 when 

Jackson admitted to Dr. Korpi he had committed the sex offenses; 

• The trial court should impose a lesser sanction such as the exclusion 

of evidence regarding Dr. Fisher’s 2020 interview, a late discovery instruction, and/or 

the reopening of Dr. King’s direct examination; and 

• None of Dr. Fisher’s diagnostic impressions and risk assessments 

had changed, and what Dr. Fisher testified to at his deposition was the same information 

presented in the September 2019 report. 

The prosecutor argued that nothing short of the remedy of witness 

preclusion would be fair to address Jackson’s discovery violations: “The People’s 

5

 At the hearing, defense counsel stated: “[I]t’s 100 percent my error, your 

Honor . . . . When I didn’t see an email, I figured that I needed to disclose it at that time, 

and it’s my error.” 
15

whole strategy with this trial would have been different had I known that this was, for 

one, at [defense counsel’s] direction that all of a sudden her client is copping, not some 

internal growth but a tactic legally. . . . Would have completely impacted whether the 

People would have brought any of the statements of Jackson in had he known at the end 

of his case, virtually, . . . by the way the defense expert is going to completely agree and 

say that he cops to everything.” The prosecutor further argued it was impossible to 

“unring the bell” after he had already brought in unspecified statements by Jackson 

through the prosecution’s expert witnesses: “Had the People known about what Mr. 

Jackson had said to Dr. Fisher, it would have enormously impacted on whether any of 

Mr. Jackson’s statements would have been brought in through the People’s experts in 

the first place. So [defense counsel’s] suggestion that that somehow makes the People 

whole is absurd. It’s absurd.” 

The trial court granted the prosecution’s motion to exclude Dr. Fisher’s 

expert testimony at trial: “The problem that the court has is, as the People have indicated, 

they can’t unring that bell. The approach that they took on the case was premised on the 

information that they had regarding Dr. Fisher, and the only published for discovery 

information they had was on a report that predated his interview of February 20th, 2020, 

with the defendant where I find that there was a material change in information provided 

by your client. That information was not disclosed, nor was there an expert exchange as 

was required under [Code of Civil Procedure] 2034.300. [¶] The court made its best 

efforts to try and conduct the trial and provide the petitioner with the opportunity to 

conduct a deposition mid trial. I find through no fault of the petitioner that there was a 

repeated discovery violation and a failure to provide information regarding updated 

information that Dr. Fisher had considered and relied upon, that that discovery violation 

continued up to and through last Thursday’s attempt at deposing Dr. Fisher, and that that 

has put the People in a completely untenable position such that there is no other remedy 

than the remedy called for in [Code of Civil Procedure section] 2034.300, and that is to 
16

strike Dr. Fisher as a testifying witness for [Jackson]. [¶] So he is hereby stricken from 

[Jackson’s] witness list, and he will not be permitted to testify. [¶] The court further 

orders reimbursement to petitioner, $600 for deposition costs, $1,270.52 for an expedited 

transcript of that deposition, for a total cost of $1,870.52 due to petitioner.” 

Defense counsel immediately moved for a mistrial on the grounds that 

Jackson had rights under the 6th and 14th Amendments to the United States Constitution

in the SVP proceeding and specifically had a right to an expert at trial. The trial court 

denied the motion. 

X.

THE JURY FINDS JACKSON TO BE AN SVP AND THE TRIAL COURT DENIES JACKSON’S 

MOTION FOR A NEW TRIAL.

In September 2020, a jury found Jackson to be an SVP within the meaning 

of the SVPA. In October 2020, Jackson filed a motion for a new trial on the ground the 

trial court erred by granting the prosecution’s motion seeking to exclude Dr. Fisher as an 

expert witness; the trial court denied the motion on the ground nothing had changed since 

the court excluded Dr. Fisher from testifying at trial. 

In October 2020, the trial court ordered Jackson committed to Coalinga 

State Hospital for an indeterminate term. Jackson appealed. 

DISCUSSION

I.

BACKGROUND

Citing section 2034.300 of the Code of Civil Procedure, the trial court 

precluded Jackson’s expert witness from testifying at trial because defense counsel had 

failed to timely (1) re-serve an expert designation after trial was continued and discovery 

was reset in July 2020; (2) disclose to the prosecution Dr. Fisher’s February 2020 

meeting with Jackson at which Jackson first admitted to Dr. Fisher that he had committed 
17

the two qualifying prior sex offenses and his sex abuse of T.; and (3) produce to the 

prosecution the notes Dr. Fisher took regarding that February 2020 meeting with Jackson. 

Section 2034.300 of the Code of Civil Procedure provides in relevant part 

that “on objection of any party who has made a complete and timely compliance with 

Section 2034.260, the trial court shall exclude from evidence the expert opinion of any 

witness that is offered by any party who has unreasonably failed to do any of the 

following: [¶] (a) List that witness as an expert under Section 2034.260. [¶] (b) Submit 

an expert witness declaration. [¶] [or] (c) Produce reports and writings of expert 

witnesses under Section 2034.270.” (Italics added.)

Here, Jackson had identified Dr. Fisher as an expert witness for trial and 

submitted an expert witness declaration regarding Dr. Fisher in January 2020, before the 

February 2020 trial date, and again in May 2020, before the July trial date. However, he 

did not re-serve those documents on the prosecution after the trial court granted the 

prosecution’s second motion to continue the trial to August and “reset discovery.” In its 

motion, the prosecution argued that Dr. Fisher’s expert testimony must be excluded from 

trial by operation of Code of Civil Procedure section 2034.300. 

In an effort to avoid Jackson’s forfeiture of his sole expert witness at trial, 

the trial court deferred ruling on the prosecution’s motion seeking to exclude Dr. Fisher 

from testifying at trial and fashioned a “nonstatutory remedy” of providing the 

prosecution the opportunity to depose Dr. Fisher during a scheduled break in the 

prosecution’s case-in-chief. The trial court denied the prosecution’s request that Dr. 

Fisher’s deposition be scheduled before jury selection. 

The trial court ultimately granted the prosecution’s originally sought-after 

relief of excluding Dr. Fisher’s testimony after the prosecution learned that Dr. Fisher, in 

February 2020, had had an hour-long conversation with Jackson during which Jackson 

first admitted committing the qualifying sex offenses and the sex offense against T. At 

the deposition, the prosecution received a three-page document containing Dr. Fisher’s 
18

handwritten notes about that conversation. Presented with this information of delayed 

disclosures, the trial court concluded there was no other possible appropriate remedy but 

to exclude Dr. Fisher’s trial testimony under section 2034.300 of the Code of Civil 

Procedure.

It is true Jackson failed to re-serve his expert witness designation in July or 

August 2020 after the trial was again continued and the prosecution served a demand for 

an exchange of expert information. And there is no dispute that defense counsel did not 

disclose Dr. Fisher’s 2020 conversation with Jackson or Dr. Fisher’s attendant notes until 

Dr. Fisher’s deposition was held during a break in the trial toward the end of the 

prosecution’s case-in-chief.

Jackson argues any discovery violations were not unreasonable under the 

circumstances of this case within the meaning of section 2034.300, and the trial court

abused its discretion by precluding Dr. Fisher’s testimony as a discovery sanction. 

(Landau v. Superior Court, supra, 32 Cal.App.5th at p. 1080 [“We generally review 

discovery orders for an abuse of discretion”].) We do not need to evaluate whether 

Jackson’s discovery violations were reasonable under the statute because even if they 

were unreasonable, our analysis does not end. Instead, we must consider statutory rights 

conferred by the SVPA as well constitutional rights that attach in SVP proceedings in 

evaluating Jackson’s contention of error.

II.

SECTION 6603, THE RIGHT TO DUE PROCESS IN SVP PROCEEDINGS, AND THE OTTO 

FACTORS.

“Pursuant to section 6603, subdivision (a),[6]

a person subject to 

commitment under the [SVPA] has a right to counsel and a right to retain experts or 

6

 Section 6603, subdivision (a) provides in part: “A person subject to this article is 

entitled to a trial by jury, to the assistance of counsel, to the right to retain experts or 

professional persons to perform an examination on the person’s behalf, and to have 

access to all relevant medical and psychological records and reports.” (Italics added.)
19

professionals to perform examinations on his or her behalf—and of course he or she also 

has a right to present the resulting evidence to the jury.” (Albertson v. Superior Court, 

supra, 25 Cal.4th at p. 803, italics added; see also People v. Superior Court (Smith),

supra, 6 Cal.5th at p. 463.) Civil commitment in SVP proceedings inherently involves a 

significant restraint on the defendant’s liberty. Therefore, a defendant in such a 

proceeding “is entitled to certain due process protections.” (Moore v. Superior Court, 

supra, 50 Cal.4th at p. 818.)

With regard to due process, the California Supreme Court has explained: 

“[P]roceedings under the SVPA, in common with proceedings under other civil 

commitment statutes, are civil proceedings with consequences comparable to a criminal 

conviction—involuntary commitment, often for an indefinite or renewable period, with 

associated damage to the defendant’s name and reputation.” (People v. Hurtado (2002) 

28 Cal.4th 1179, 1192 (Hurtado); see People v. Force, supra, 39 Cal.App.5th at p. 514, 

fn. 2 [SVP proceedings “are rooted in criminal convictions and therefore retain the due 

process rights associated with criminal trials,” affording defendants in such proceedings a 

constitutional right to present a defense, which includes calling witnesses in his favor and 

testifying on his own behalf].) In Hurtado, supra, 28 Cal.4th at pages 1192-1194, the 

California Supreme Court recognized that California courts have relied on burden of 

proof decisions to hold that the standard of Chapman v. California (1967) 386 U.S. 18 

(Chapman) applies to federal constitutional error in civil commitment proceedings. 

Under the high standard of Chapman, federal constitutional error is reversible unless 

shown to be harmless beyond a reasonable doubt. (Ibid.) The Hurtado court concluded 

that the Chapman standard “necessarily governs review under the SVPA.” (Hurtado, 

supra, at p. 1194.) We therefore apply the standard of Chapman, supra, 386 U.S. 18

here.

Upon concluding that a defendant in an SVP proceeding is entitled to due 

process protections, “‘the question remains what process is due.’” (Otto, supra, 26 
20

Cal.4th at p. 210.) In Otto, the Supreme Court identified the following four factors (the 

Otto factors) to be considered and applied in making that determination: “(1) the private 

interest that will be affected by the official action; (2) the risk of an erroneous deprivation 

of such interest through the procedures used, and the probable value, if any, of additional 

or substitute procedural safeguards; (3) the government’s interest, including the function 

involved and the fiscal and administrative burdens that the additional or substitute 

procedural requirement would entail; and (4) the dignitary interest in informing 

individuals of the nature, grounds, and consequences of the action and in enabling them 

to present their side of the story before a responsible government official.” (Ibid.)

III.

APPLICATION OF THE OTTO FACTORS ESTABLISHES THE DEFENDANT’S DUE PROCESS 

RIGHT TO PRESENT EXPERT WITNESS TESTIMONY AT AN SVP TRIAL.

The parties have cited no published legal authority specifically addressing 

what process is due in the context of expert witness testimony preclusion in SVP trials,

and we have found none.7

 Applying the Otto factors here, first, we conclude there is no 

question that “the private interests that will be affected by [a civil commitment under the 

SVPA] are significant limitations on [the defendant’s] liberty, the stigma of being 

7 In People v. McKee, supra, 47 Cal.4th at page 1192, the California Supreme Court

addressed an SVP’s due process interest in having the assistance of an expert witness in 

the SVP’s effort to petition the trial court under former section 6608 for his or her release 

from civil commitment. The court observed: “If the state involuntarily commits 

someone on the basis of expert opinion about future dangerousness, places the burden on 

that person to disprove future dangerousness, and then makes it difficult for him to access 

his own expert because of his indigence to challenge his continuing commitment, that 

schema would indeed raise a serious due process concern.” (Ibid.) Explaining “[w]e 

construe statutes when reasonable to avoid difficult constitutional issues,” the Supreme 

Court held: “Given that the denial of access to expert opinion when an indigent 

individual petitions on his or her own to be released may pose a significant obstacle to 

ensuring that only those meeting SVP commitment criteria remain committed, we 

construe section 6608, subdivision (a) . . . to mandate appointment of an expert for an 

indigent SVP who petitions the court for release.” (Id. at p 1193.) As so interpreted, the 

court concluded former section 6608 did not violate the due process clause. (Ibid.) 
21

classified as an SVP, and subjection to unwanted treatment.” (Otto, supra, 26 Cal.4th at 

p. 210.) 

Second, we consider the risk of an erroneous deprivation of such interests 

through the procedures used, and the probable value, if any, of any additional or 

substitute safeguards. The preclusion of expert testimony on behalf of the defense would 

seriously limit the defendant’s ability to respond to the prosecution’s expert testimony.

If the only defense expert witness is precluded from testifying, there would 

be no expert witness to rebut the prosecution’s experts’ testimony that the defendant has a 

diagnosed mental disorder that would make him a danger to the health and safety of 

others and would make it likely he will engage in future predatory acts of sexually violent 

criminal behavior if released from custody. (See People v. McKee, supra, 47 Cal.4th at 

p. 1192 [expert witness testimony “is critical in an SVP commitment proceeding”]; see 

also Ake v. Oklahoma (1985) 470 U.S. 68, 81 [“Psychiatry is not . . . an exact science, 

and psychiatrists disagree widely and frequently on what constitutes mental illness, on 

the appropriate diagnosis to be attached to given behavior and symptoms, on cure and 

treatment, and on likelihood of future dangerousness”].)

Third, the SVPA “articulates the strong government interest in protecting 

the public from those who are dangerous and mentally ill.” (Otto, supra, 26 Cal.4th at 

p. 214.) Recognizing that a defendant in an SVP proceeding has a due process right to 

critical expert witness testimony does not interfere with the strong government interest in 

protecting the public. Defense expert testimony may show that the defendant is not an 

SVP. The government has no interest in protecting the public from non-SVP’s.

Finally, we consider whether a right to have an expert witness testify for the 

defense is necessary to safeguard a defendant’s “dignitary interest” in an SVP 

proceeding. (Otto, supra, 26 Cal.4th at p. 210.) The Otto court explained that a person 

subject to the SPVA has a “dignitary interest in being informed of the nature, grounds,

and consequences of the SVP commitment proceeding” and in “presenting his side of the 
22

story before a responsible government official.” (Id. at p. 215.) If the trial court 

precludes a defendant’s expert witness from testifying at an SVP trial, it is hard to see 

how the defendant can present his or her side of the story of whether the defendant is an 

SVP and whether it is likely the defendant would engage in future predatory acts of 

sexually violent criminal behavior if released from custody.

Having considered and applied the Otto factors, we conclude a defendant in 

an SVP proceeding has a due process right to present expert witness testimony at trial. 

(People v. Angulo (2005) 129 Cal.App.4th 1349, 1361 [“Due process in an SVPA 

proceeding is satisfied where ‘the defendant has the opportunity to thoroughly present his 

side of the story’”]; People v. Superior Court (Howard) (1999) 70 Cal.App.4th 136, 154

[due process under the SVPA is preserved when the mandated proceedings provide the 

defendant “the opportunity to thoroughly present his side of the story”].) 

IV.

SECTION 2034.300 OF THE CODE OF CIVIL PROCEDURE CANNOT BE APPLIED 

WITHOUT CONSIDERATION OF WELFARE AND INSTITUTIONS CODE SECTION 6603,

SUBDIVISION (a) AND THE DEFENDANT’S DUE PROCESS RIGHT TO PRESENT EXPERT 

WITNESS TESTIMONY IN AN SVP TRIAL.

Before and during trial, the prosecution argued that if a party is found to 

have unreasonably violated expert witness disclosure requirements, section 2034.300 of 

the Code of Civil Procedure commands that “the trial court shall exclude from evidence 

the expert opinion of any witness.” (Italics added.) In other words, the prosecution

argued that upon finding a party unreasonably violated certain disclosure requirements, 

the trial court is compelled to exclude that party’s expert witness from testifying at trial. 

It is true a defendant in an SVP proceeding cannot be free to circumvent 

applicable discovery statutes, given the government’s strong interest in protecting the 

public from those who are dangerous to others. (See Otto, supra, 26 Cal.4th at p. 214.) 

Even a defendant in a criminal action must comply with discovery rules. However, 

“[p]reclusion sanctions may be imposed against a criminal defendant only for the most 
23

egregious discovery abuse. Specifically, such sanctions should be reserved to those cases 

in which the record demonstrates a willful and deliberation violation which was 

motivated by a desire to obtain a tactical advantage at trial such as the plan to present 

fabricated testimony.” (People v. Edwards (1993) 17 Cal.App.4th 1248, 1263.)8

 

But here, the trial court read the word “shall” in section 2034.300 of the 

Code of Civil Procedure in a vacuum. Even assuming for purposes of our analysis that

Jackson’s discovery violations were unreasonable, this reading directly conflicts with (1) 

Jackson’s specific right in this SVP proceeding to present an expert witness at trial under

section 6603, subdivision (a), and (2) his constitutional due process right to present such 

evidence and be provided the opportunity to tell his side of the story. Given this conflict, 

consideration of the applicability section 2034.300 of the Code of Civil Procedure in 

evaluating the trial court’s expert witness preclusion order is necessarily only the start of 

the analysis and not, as argued by the prosecution, the end.

V.

THE TRIAL COURT’S ORDER EXCLUDING DR. FISHER’S TRIAL TESTIMONY VIOLATED 

JACKSON’S RIGHT TO DUE PROCESS AND CONSTITUTED PREJUDICIAL ERROR.

Applying due process principles discussed ante to the record before us, we 

conclude the trial court for several reasons erred by selecting the preclusion of Dr. 

Fisher’s expert witness testimony as the remedy for Jackson’s discovery violations. We 

do not regard this issue as a close one.

The Supreme Court has explained that, generally speaking, the civil 

discovery statutes “were intended to curtail surprises, enable each side to learn as much 

as possible about the strengths and weakness of its case,” and thereby facilitate, among 

8

 It is well established that in a criminal case, the defendant has the due process right to 

the assistance of expert witnesses. (Ake v. Oklahoma, supra, 470 U.S. at pp. 83, 87, fn.

13.) “‘The Sixth and Fourteenth Amendments to the United States Constitution also 

guarantee a defendant’s right to present the testimony of these expert witnesses at trial.’” 

(People v. Nieves (2021) 11 Cal.5th 404, 449.)
24

other things, efficient trials. (Williams v. Superior Court (2017) 3 Cal.5th 531, 543. fn. 3, 

italics omitted.) Here, any argument that the prosecution was taken by surprise that 

Jackson intended to call Dr. Fisher as his expert witness at trial, or was in any way 

prejudiced simply because Jackson did not re-serve his expert witness designation a third 

time within a seven-month period, strains credulity. 

The record shows: (1) Dr. Fisher had evaluated Jackson and produced the

September 2019 report; (2) in January 2020, Jackson first served his expert witness 

designation and declaration identifying Dr. Fisher as his sole expert witness (neither the 

prosecution at trial nor the Attorney General on appeal have suggested that Jackson’s 

expert witness designation and declaration were in any way deficient); (3) in May 2020, 

Jackson re-served his expert witness designation and declaration naming Dr. Fisher as his 

sole expert witness; (4) although Jackson did not respond by August 3 to the 

prosecution’s most recent demand for an exchange of expert witness information, three 

days after his response was due, Jackson served his trial witness list which included Dr. 

Fisher; and (5) the prosecution had the opportunity to and did take Dr. Fisher’s deposition 

and obtained all requested documents from Dr. Fisher before concluding its case-in-chief 

at trial.

The prosecution argued that the disclosure of Dr. Fisher’s February 2020 

meeting with Jackson (and related notes) during his deposition taken in the midst of trial 

also compelled the exclusion of Dr. Fisher’s testimony. Defense counsel acknowledged 

that she should have disclosed Dr. Fisher’s February 2020 conversation with Jackson 

sooner than she did, and she agreed she should have produced Dr. Fisher’s notes related 

to that conversation three days before his deposition. For several reasons, the record does 

not support the prosecution’s claims of undue prejudice as a result of the delayed 

disclosures, or that absolute expert witness preclusion would be an appropriate—much 

less a necessary—sanction under the circumstances of the case. 
25

First, although Dr. Fisher’s meeting with Jackson in February 2020 was 

generally undisclosed until the eve of Dr. Fisher’s deposition, the only “new” information 

gained from that meeting was that Jackson admitted for the first time to Dr. Fisher that he 

had committed the underlying sex offenses.

9

Second, shortly after his February 2020 conversation with Dr. Fisher, 

Jackson admitted committing the same sex offenses directly to Dr. Korpi during his 

updated evaluation of Jackson in March 2020, and to Dr. King during his June 2020 

evaluation of Jackson. Therefore, the prosecution was well aware, as early as March 

2020, that Jackson had jettisoned his past denials and admitted he had committed those 

sex offenses.

Third, Dr. Fisher’s expert opinion, as explained in the September 2019 

report and during his deposition, encompassed opinions on several central issues at trial, 

including whether Jackson had a mental illness that made him dangerous and likely to 

reoffend. When and whether Jackson had admitted or denied qualifying offenses or other 

sex offenses to Dr. Fisher was at most a relatively small aspect of the scope of Dr. 

Fisher’s proposed expert witness trial testimony.

Fourth, the prosecutor proceeded to take Dr. Fisher’s deposition as 

scheduled and did not identify any information he was unable to discover during that 

deposition as a result of the delayed disclosures. 

Fifth, the deposition occurred while the prosecution was still presenting its 

case-in-chief and while one of its experts, Dr. Korpi, was still under redirect examination. 

The record does not show why the delayed disclosures were not remediable by simply 

eliciting further expert testimony from the prosecution’s experts.

In support of his request that the trial court exclude Dr. Fisher’s testimony, 

the prosecutor argued in general terms that, had he known of the February 2020 meeting 

9

 Although Jackson had pleaded guilty to several of the offenses, he had previously 

denied committing them to Dr. Fisher.
26

and Jackson’s admissions before trial, he would have structured his entire case-in-chief 

differently and would not have had to elicit Jackson’s statements denying he committed 

the qualifying sex offenses through his own experts. The prosecutor never explained how

he would have changed his presentation, what statements he had to elicit, or why either 

fact caused the prosecution undue prejudice. 

Defense counsel proposed that the trial court issue a different sanction such 

as a jury instruction on late disclosure or the preclusion of evidence regarding the 

February 2020 meeting. The trial court declined imposing any other sanctions and 

instead selected the nuclear option of excluding Jackson’s sole expert witness from 

testifying at all at trial. This ruling forced Jackson to proceed at trial without any expert 

witness testimony to rebut the testimony of the prosecution’s two expert witness, Dr. 

Korpi and Dr. King, on the dispositive issues at trial. 

The trial court’s ruling preventing Jackson from presenting any expert 

witness testimony in his defense at trial denied Jackson constitutional due process. We 

cannot conclude the trial court’s error was harmless beyond a reasonable doubt. 

(Chapman v. California, supra, 386 U.S. at pp. 22-24.) The Attorney General cannot

dispute that Dr. Fisher’s expert testimony was relevant, material, and crucial to the 

defense. Nor can he dispute that the preclusion of that testimony significantly curtailed 

Jackson’s right to present his side of the story. Indeed, it is fair to say that without expert 

testimony to challenge the prosecution’s two expert witnesses, Jackson had no chance of 

prevailing at trial. Jackson is entitled to a new trial.

Nothing in this opinion is intended to suggest that the preclusion of a 

defense expert witness from an SVP trial is always reversible error. Instead, the Civil 

Discovery Act must be applied in each SVP proceeding in light of section 6603 and the

constitutional due process rights at stake. Using the analytical framework we have 

described, rulings are reviewed on a case-by-case basis. 
27

Because we reverse and remand to the trial court for a new trial, we do not 

need to address Jackson’s other contentions of error that he received ineffective 

assistance of counsel and that the trial court erred by denying his motion for a 

continuance and motion for a new trial.

DISPOSITION

The judgment is reversed and the matter is remanded for a new trial on all 

issues.
