COURT OF APPEAL, FOURTH APPELLATE DISTRICT
DIVISION ONE
STATE OF CALIFORNIA
M.S., D086445
Plaintiff and Appellant,
v. (Super. Ct. No. 37-2022-
00040516-CU-PO-CTL)
COUNTY OF SAN DIEGO,
Defendant and Respondent.
APPEAL from a judgment of the Superior Court of San Diego County,
Gregory W. Pollack, Judge. Reversed.
Herman Law and Sarah E. Serrano, for Plaintiff and Appellant.
Office of County Counsel, Sofia L. Rezvani and Lindsey M. Burnette,
for Defendant and Respondent.
Plaintiff M.S. sued the County of San Diego (the County) alleging its
employee negligently failed to protect her from sexual abuse when she was a
child in foster care nearly 40 years ago. The superior court granted summary
judgment in favor of the County, concluding it was entitled to discretionary
act immunity under Government Code1 section 820.2.
M.S. appeals, arguing discretionary act immunity does not apply. We
agree with M.S. and find the County has not met its burden of establishing a
County employee undertook the requisite conscious balancing of risks and
advantages before making a decision regarding allegations of sexual abuse.
The County argues we should still affirm because M.S. cannot establish
that any employee knew of the risk of abuse before she was placed in the
home and because the evidence does not otherwise show the social worker
was negligent. The County also argues that, because M.S. cannot name the
social worker to whom she reported the abuse, she cannot establish that any
individual would be liable for negligence and, thus, cannot establish that the
County is vicariously liable. Accepting M.S.’s evidence as true, she told her
assigned social worker that she was being sexually abused, the social worker
failed to intervene, and the abuse continued for months. We do not think her
inability to name the specific County social worker defeats her claim.
For these reasons, as explained more fully below, we reverse.
FACTUAL AND PROCEDURAL BACKGROUND
In 1985, when M.S. was approximately 11 years old, she was removed
from the custody of her biological mother. In 1986, she was placed in a foster

Code.

home with John and Linda DeMarco. M.S. was continually sexually abused
by her foster brother while she resided in the DeMarco home.
M.S. testified she was “visited by a social worker after the incidents [of
abuse] first started to happen,” and she told the social worker her foster
brother had been “standing at the door with his thing out, fondling his thing”;
“[t]ouching [M.S.] on [her] vagina and on [her] breast”; and “[r]ubbing his
penis on [her] vagina and putting his mouth at [her] vagina.” Although she
reported the abuse to the same social worker on at least one other occasion,
“the social worker tried to convince [M.S.] that her placement in the DeMarco
home was fine.” The social worker did not intervene, “no law enforcement
official ever came to speak to” M.S., and the assaults continued “the whole
time” she was in the care of the DeMarcos from late 1986 through mid-1988.
M.S. also told her mother that she was being sexually abused. The
mother reported the abuse to the County employee who arranged her visits
with M.S. and was told by that employee, “ ‘We’ll look into it.’ ” According to
M.S., her mother and grandfather “orally reported” the abuse to the County
approximately one month before she was removed from the DeMarco home in
1988.
M.S. filed this lawsuit against the County in 2022. In 2025, the County
filed a motion for summary judgment arguing, among other things, that M.S.
could not identify a specific employee who has been negligent and that the
County was entitled to discretionary act immunity. The trial court granted
the motion, finding the County was immune from liability.
The court relied exclusively on K.C. v. County of Merced (2025)
109 Cal.App.5th 606, review granted June 25, 2025, S290435 (K.C.), which it
found “directly on point.” According to the trial court, the plaintiff in K.C.
“alleged facts strikingly similar to those facts alleged in [this] case,” including
3
that the plaintiff “was sexually assaulted at two separate foster care
placements in the 1970s and that [she] had given notice of the abuse to
Merced County via its social workers, but Merced County thereafter
undertook no investigative or corrective action.” The court concluded that,
because the court in K.C. affirmed the trial court’s order sustaining a
demurrer on the basis of discretionary act immunity, the County here was
entitled to summary judgment on the same ground.
DISCUSSION
A. Standard of Review
We independently review the trial court’s order granting the County’s
motion for summary judgment. (Ryan v. Real Estate of Pacific, Inc. (2019)
32 Cal.App.5th 637, 642.) A defendant is only entitled to summary judgment
if “there is no genuine dispute of material fact and . . . it is entitled to
judgment as a matter of law.” (Jones v. Awad (2019) 39 Cal.App.5th 1200,
1207.) We “may not weigh the evidence but must instead view it in the light
most favorable to the opposing party and draw all reasonable inferences in
favor of that party.” (Weiss v. People ex rel. Department of Transportation
(2020) 9 Cal.5th 840, 864.)
B. The County Has Not Shown It Is Entitled to Immunity
M.S. argues the trial court improperly granted summary judgment on
the basis of discretionary act immunity. We agree.
Public employees are liable for their own torts unless otherwise
provided by statute. (§ 820, subd. (a).) The County, as a “public entity,” is
vicariously “liable for injury proximately caused by an act or omission of an
employee” acting “within the scope of [her] employment if the act or omission
would . . . have given rise to a cause of action against that employee.”
(§ 815.2, subds. (a)–(b).)
4
A public employee and, by extension, her public entity employer cannot
be held liable for so-called “discretionary” acts or omissions. (See, e.g.,
Caldwell v. Montoya (1995) 10 Cal.4th 972, 979–980 (Caldwell).) Specifically,
section 820.2 provides: “Except as otherwise provided by statute, a public
employee is not liable for an injury resulting from his act or omission where
the act or omission was the result of the exercise of the discretion vested in
him, whether or not such discretion be abused.”
Because “almost all acts involve some choice among alternatives”
(Caldwell, supra, 10 Cal.4th at p. 981), the term “discretionary” in this
context is a term of art. This variety of “[i]mmunity is reserved for those
‘basic policy decisions [which have] . . . been [expressly] committed to
coordinate branches of government,’ and as to which judicial interference
would thus be ‘unseemly.’ ” (Ibid.) Discretionary act immunity does not
extend to “lower-level, or ‘ministerial,’ decisions that merely implement a
basic policy already formulated.” (Ibid.) The Supreme Court has framed the
distinction as one between “policy and operational judgments.” (Ibid.)
The weight of modern authority holds that “decisions of child welfare
agency employees—regarding determinations of child abuse, the potential
risk to a child, placement of a child, removal of a child, and other resultant
actions—are subjective discretionary ones.” (B.H. v. County of San
Bernardino (2015) 62 Cal.4th 168, 191–192 (B.H.); see, e.g., D.G. v. Orange
County Social Services Agency (2025) 108 Cal.App.5th 465, 473 (D.G.)
[quoting B.H.]; Jacqueline T. v. Alameda County Child Protective Services
(2007) 155 Cal.App.4th 456, 466 [“[A] social worker's decisions relating to . . .
the investigation of child abuse, removal of a minor, and instigation of
dependency proceedings, are discretionary decisions subject to immunity
under section 820.2.”]; Becerra v. County of Santa Cruz (1998) 68 Cal.App.4th
5
1450, 1466 [“whether to intervene and discontinue a child’s placement [in a
foster home], is a discretionary placement decision”].)
But even if the kind of act or omission at issue is a discretionary one,2
discretionary act immunity only applies if the act or omission at issue was in
fact an exercise of discretion. The employee specific “immunity applies only
to deliberate and considered policy decisions, in which a ‘[conscious] balancing
[of] risks and advantages . . . took place. The fact that an employee normally
engages in ‘discretionary activity’ is irrelevant if, in a given case, the
employee did not render a considered decision.’ ” (Caldwell, supra, 10 Cal.4th
at p. 981.)
There is no evidence in this record from which we could conclude that
any employee rendered a considered decision regarding M.S.’s reports of
abuse. That is fatal to the County’s claim of immunity. (See D.G, supra,
108 Cal.App.5th at p. 474 [reversing grant of summary judgment where there
was “simply no evidence in the record that” the assigned social worker or
other employee in fact “exercised discretion” in maintaining child’s foster
placement].)
Where a defendant moves for summary judgment on the ground there
is an affirmative defense to liability, it is the defendant’s burden to establish
the defense. (See Code Civ. Proc., § 437c, subd. (p)(2) [“A defendant . . . has
met [its] burden of showing that a cause of action has no merit if the party
has shown . . . that there is a complete defense to the cause of action.”].)
2 In light of our conclusion below, we decline to address M.S.’s contention
that decisions regarding removal from foster care are different from decisions
about removing a child from her parent’s care. Rather, we assume that the
social worker’s acts or omissions here are the kind generally entitled to
discretionary act immunity.
6
Thus, “ ‘[t]he burden on a defendant moving for summary judgment based
upon the assertion of an affirmative defense is heavier than the burden to
show one or more elements of the plaintiff’s cause of action cannot be
established. Instead of merely submitting evidence to negate a single
element of the plaintiff’s cause of action, . . . “the defendant has the initial
burden to show that undisputed facts support each element of the affirmative
defense” [citations]. The defendant must demonstrate that under no
hypothesis is there a material factual issue requiring trial. [Citation.] If the
defendant does not meet this burden, the motion must be denied.’ ”
(Ehrenkranz v. San Francisco Zen Center (2026) 118 Cal.App.5th 977, 989–
990.)
Given the absence of evidence about what the social worker did
following M.S.’s reports of abuse, the County has not met its summary
judgment burden.3 For purposes of this motion, we must draw all reasonable
inferences in favor of M.S. We thus cannot infer that the social worker’s
apparent inaction was the result of a considered judgment.
The County suggests we do not need any evidence regarding the social
worker’s actions because “a social worker’s decisions in responding to a report
of child abuse and determining whether to remove a child from a foster home”
are categorically subject to discretionary immunity. This argument is
contrary to the Supreme Court’s holdings in Caldwell and Johnson v. State of
3 The County, citing Code of Civil Procedure section 437c, subdivision
(p)(2), appears to concede it has the burden of establishing this defense. We
accept this concession, as the analysis in Quigley v. Garden Valley Fire
Protection Dist. (2019) 7 Cal.5th 798, 808–815, strongly suggests that
discretionary act immunity under section 820.2 is an affirmative defense that
must be pled and proved by the defendant.
7
California (1968) 69 Cal.2d 782 (Johnson), which require inquiry into
whether an employee “consciously exercised discretion in the sense of
assuming certain risks in order to gain other policy objectives.” (Johnson, at
p. 794, fn. 8.) To the extent any court of appeal decision cited by the County
could be read to support a contrary conclusion, we are bound to follow the
Supreme Court. We specifically do not find the analysis in K.C. persuasive
insofar as it suggests that if a social worker fails to respond to reports of
sexual abuse, a court can presume the failure resulted from an exercise of
discretion even in the absence of allegations regarding what the social worker
actually did. (See K.C., supra, 109 Cal.App.5th at p. 619.) This
impermissibly collapses the two-step analysis provided by the Supreme Court
and, here, would contravene the summary judgment standard and invert the
parties’ burdens.
Finally, the County suggests it should be immune because M.S. was
ultimately removed from the DeMarco home in 1988, roughly one month after
her mother and grandfather reported the abuse to a social worker. Assuming
this specific action somehow reflects a considered judgment by an employee,
M.S. reported the abuse the first time her social worker visited and she was
not removed from the placement for many months.4 There is no evidence
4 The County notes that M.S. cannot remember when she reported the
abuse. M.S. claims the abuse began in her first month after she was placed
with the DeMarcos in late 1986. She says she reported the abuse the “first
time the social worker visited” her in the DeMarco home, and agreed this
visit was “after the incidents [of abuse] first started to happen.” She was not
removed from the placement until 1988. Viewing the evidence in the light
most favorable to M.S., we think it reasonable to infer she was not removed
from her placement for many months after her first report to the social
worker.
8
that would suggest that leaving M.S. in the foster home during this time
resulted from an exercise of discretion. Accordingly, the County is not
entitled to summary judgment.
C. Other Genuine Disputes of Material Fact Preclude Summary Judgment
The County argues that even if it is not entitled to discretionary act
immunity, it is still entitled to summary judgment. We “ ‘will affirm a
summary judgment if it is correct on any ground that the parties had an
adequate opportunity to address in the trial court, regardless of the trial
court’s stated reasons.’ ” (Nicoletti v. Kest (2023) 97 Cal.App.5th 140, 144.)
However, the County has not shown it is entitled to summary judgment on
any alternative ground.
First, the County claims M.S. cannot name the particular social worker
to whom she reported the abuse, and the County cannot be held vicariously
liable for the actions of an unnamed employee. The County relies exclusively
on Koussaya v. City of Stockton (2020) 54 Cal.App.5th 909, for this
proposition. But in that case, the court found there could be no vicarious
liability where “summary judgment was properly granted as to the
[individual] defendants in this case,” and “to the extent [her] claims [we]re
vicarious to the officer defendants’ actions in this case,” their employer could
not be vicariously liable. (Id. at p. 944.) Otherwise, the plaintiff’s “appellate
briefing [did] not specifically argue that any individual” behaved tortiously,
instead seeking to aggregate the actions of multiple individuals. (Id. at
pp. 945–947.)
Here, M.S. identifies a particular social worker to whom she reported
abuse, she just cannot identify them by name. For purposes of this motion,
we must infer that the abuse was reported at least twice to the same social
worker who was a County employee. We see no reason M.S.’s inability to
9
provide the name of her social worker would defeat her claim on summary
judgment. (See, e.g., Sen. Com. on Judiciary, Rep. on Sen. Bill No. 42 (1963
Reg. Sess.) 2 Sen. J. (1963 Reg. Sess.) pp. 1887–1888 [“Under [section 815.2],
it will not be necessary in every case to identify the particular employee upon
whose act the liability of the public entity is to be predicated. All that will be
necessary will be to show that some employee of the public entity tortiously
inflicted the injury in the scope of his employment under circumstances
where he would be personally liable.”].)
Next, the County argues M.S. “cannot establish that any County
employee had actual knowledge of [her foster brother’s] propensity to commit
sexual abuse prior to her report to the social worker.” This does not dispose
of the County’s potential liability for failing to remove M.S. from the
DeMarcos’ home or otherwise take action to protect M.S. after her reports.
Finally, the County argues there is no evidence the social worker
breached a duty of care owed to M.S. because “she cannot recall when she”
reported the abuse, “she has no personal knowledge of whether the social
worker to whom she reported thereafter spoke with her foster or biological
family about the alleged sexual abuse,” and “she was removed from the
DeMarco home approximately one month after her biological mother and
grandfather made subsequent reports of abuse.” But, viewing the record in
the light most favorable to the nonmoving party, M.S. reported the abuse to
the same social worker on at least two occasions, and the abuse continued for
months before she was removed. The record supports the inference that the
social worker failed to take any action based on M.S.’s reports, leading M.S.
10
to suffer additional foreseeable harm. A reasonable factfinder could thus
conclude that the social worker breached the duty of care.5
DISPOSITION
The judgment is reversed. M.S. is entitled to recover her costs on
appeal.
