Sallie Kim, Magistrate Judge, Presiding
Argued and Submitted November 20, 2024
San Jose, California
Before: GRABER, FRIEDLAND, and BUMATAY, Circuit Judges. Dissent by
Judge BUMATAY.
Partial Dissent by Judge BUMATAY.
Defendant Sheriff’s deputies Stephanie Nelson and Christopher Thomas
appeal the denial of qualified immunity for their conduct during an interaction with
Plaintiff Tracy Pachote after she called the Contra Costa County Sheriff’s Office to
report having heard gunshots in her neighborhood. We reverse the district court’s
denial of qualified immunity to Nelson, but we affirm as to Thomas.
We review de novo the denial of qualified immunity. Rosenbaum v. City of
San Jose, 107 F.4th 919, 924 (9th Cir. 2024). Because this case comes to us on
Defendants’ motion for summary judgment, “[w]e ‘must view the evidence in the
light most favorable to [Plaintiff] . . . and draw all reasonable inferences in
[Plaintiff’s] favor.’” Herrera v. L.A. Unified Sch. Dist., 18 F.4th 1156, 1158 (9th
Cir. 2021) (quoting Dees v. County of San Diego, 960 F.3d 1145, 1151 (9th Cir.
2020)).
2 23-4000
1. Nelson is entitled to qualified immunity as to the seizure claim
concerning her presence on Plaintiff’s porch and her verbal statements before any
alleged use of force.
Officers are entitled to qualified immunity unless a plaintiff can show not
only that the “official’s actions violated a constitutional right,” but also that “the
right was ‘clearly established’ at the time of the violative conduct.” Nelson v. City
of Davis, 685 F.3d 867, 875 (9th Cir. 2012) (quoting Harlow v. Fitzgerald, 457
U.S. 800, 818 (1982)). Assuming, without deciding, that Nelson committed a
constitutional violation, it was not clearly established at the time she acted that her
conduct constituted an unlawful seizure. In support of her claim that the law was
clearly established, Plaintiff cites only an unpublished memorandum that postdates
the conduct at issue and a single out-of-circuit opinion. Neither could clearly
establish the law governing Nelson’s conduct, and we are aware of no other case
that did so either. See Nunes v. Arata, Swingle, Van Egmond & Goodwin (PLC),
983 F.3d 1108, 1112 (9th Cir. 2020) (per curiam) (explaining the inquiry
concerning a clearly established right). The district court therefore erred in
denying qualified immunity to Nelson on Plaintiff’s “verbal seizure” claim.1
1
Because we hold that Nelson is entitled to qualified immunity for her
conduct before the use of force, we do not consider Defendants’ argument that any
claim challenging that conduct was not adequately pleaded.
3 23-4000
2. We affirm the denial of qualified immunity to Thomas as to the excessive
force claim. To determine whether the use of force is reasonable, we balance “‘the
nature and quality of the intrusion’” against the “governmental interests at stake,”
and judge reasonableness “from the perspective of a reasonable officer on the
scene.” Graham v. Connor, 490 U.S. 386, 396 (1989) (quoting Tennessee v.
Garner, 471 U.S. 1, 8 (1985)). Drawing all reasonable inferences in Plaintiff’s
favor, as we must at this stage, when Thomas began using force, he knew that
Plaintiff was a witness who was not suspected of any crime, had heard Plaintiff
repeatedly tell Nelson to leave her front porch while Nelson refused to do so, and,
as conceded at oral argument, saw Nelson initiate physical contact against Plaintiff
by grabbing her arm and the back of her head as Plaintiff passively resisted.2
Defendants argue that Thomas could assume that Nelson had a legitimate
reason to use force against Pachote under the collective knowledge doctrine
because he had worked with Nelson for five months. But “collective knowledge
may be imputed only if there has been some ‘communication among agents’”; a
“‘close working relationship’” alone is insufficient. United States v. Villasenor,
2
The dissent contends that Thomas could not hear what Nelson and Pachote
were arguing about. But Thomas stated that he could hear the “language being
used” and that “[a]lthough Nelson’s voice was loud so as to be heard, her tone
remained calm and composed.” Drawing reasonable inferences in Plaintiff’s favor,
Thomas was aware that Nelson and Pachote were arguing about Pachote’s request
that Nelson leave her porch.
4 23-4000
608 F.3d 467, 475 (9th Cir. 2010) (quoting United States v. Ramirez, 473 F.3d
1026, 1032 (9th Cir. 2007)). Because Defendants do not allege that Thomas
communicated with Nelson prior to using force on Pachote, that doctrine is
inapposite.
Rather, Thomas had “a duty to independently evaluate [the] situation when
[he] arrive[d], if [he had] an opportunity to do so.” Rice v. Morehouse, 989 F.3d
1112, 1122 (9th Cir. 2021). Viewing the facts in the light most favorable to
Plaintiff, Thomas did have such an opportunity. A reasonable jury could find that
Thomas knew that Pachote had neither committed a crime nor posed a threat, and
that Thomas’s non-trivial use of force in pulling Pachote to the ground, dragging
her, and placing his knee on her back, causing her to tear her meniscus, was
therefore excessive. See id. at 1125. It was also clearly established that “non-
trivial force was not justified in the face of passive or even minimal resistance”
against a non-threatening individual. Id. at 1126; see Shafer v. County of Santa
Barbara, 868 F.3d 1110, 1116 (9th Cir. 2017) (holding that a reasonable jury could
find that an officer’s conduct constituted excessive force when he used a leg sweep
maneuver against an individual who did not present an immediate threat and was
suspected of committing a misdemeanor). Thomas is therefore not entitled to
qualified immunity at this stage of the proceeding.
AFFIRMED in part, REVERSED in part, and REMANDED.

BUMATAY, Circuit Judge, dissenting in part: MOLLY C. DWYER, CLERK
U.S. COURT OF APPEALS
I join the memorandum disposition reversing the district court’s denial of
qualified immunity to Contra Costa County Sheriff’s Deputy Stephanie Nelson. But
I would also reverse the district court’s denial of qualified immunity to Deputy
Christoper Thomas. I thus respectfully dissent on that issue.
Viewing the evidence in the light most favorable to Appellee Tracy Pachote,
Deputy Thomas should also receive qualified immunity. He arrived at Pachote’s
neighborhood in response to several 911 calls reporting shots fired. Pachote had
called 911 about the shots. According to Deputy Thomas, he was more than 100 feet
from Pachote’s house and facing the opposite direction while interviewing possible
witnesses, when he heard Pachote repeatedly yelling profanities—telling Deputy
Nelson to leave her residence. In response, Deputy Thomas turned around and
started walking quickly toward Pachote’s house. Deputy Thomas could not hear
what Deputy Nelson and Pachote were arguing about.
According to Pachote, which I accept, Deputy Thomas then saw Deputy
Nelson grab Pachote by the arm and the back of her head. When he arrived a few
seconds later, Deputy Thomas helped Officer Nelson and grabbed and pushed
Pachote while Nelson was pulling her by the arm. Deputies Thomas and Nelson
then pinned Pachote on the ground with their knees. All in all, a little more than 30
1
seconds elapsed between when Deputy Thomas first heard Pachote’s raised voice
and when he arrived at the ongoing struggle.
When considering qualified immunity, we view the incident “from the
perspective of a reasonable officer on the scene, rather than with the 20/20 vision of
hindsight.” Graham v. Connor, 490 U.S. 386, 396 (1989) (simplified). When
Deputy Thomas arrived at the altercation between Pachote and Deputy Nelson, it is
undisputed that he did not know the full story of what was happening. While he
observed Pachote yelling at Deputy Nelson, he did not know what precipitated the
argument. Instead, he witnessed the altercation turn physical just seconds before he
arrived at the house. Thus, Deputy Thomas did not “have an opportunity” to
“independently evaluate [the] situation” beyond what he had already observed. See
Rice v. Morehouse, 989 F.3d 1112, 1122 (9th Cir. 2021).
Given Deputy Thomas’s limited information, even if Deputy Nelson initiated
physical contact, Deputy Thomas could reasonably have believed that Deputy
Nelson had initiated a modest physical struggle to prevent Pachote from striking her
or from resisting arrest. See Est. of Strickland v. Nevada Cnty., 69 F.4th 614, 621
(9th Cir. 2023) (“Officers can have reasonable, but mistaken, beliefs as to the facts
establishing the existence of an immediate threat, and in those situations courts will
not hold that they have violated the Constitution.”) (simplified). Deputy Thomas’s
modest use of force to help Deputy Nelson subdue Pachote was thus objectively
2
reasonable under the totality of the circumstances. See Graham, 490 U.S. at 396.
Nothing in the Fourth Amendment requires police officers to assume that other
officers are acting against the law in using physical force. Nor does the Fourth
Amendment require officers to acquire perfect knowledge of the situation before
assisting another officer in a physical struggle. Instead, Deputy Thomas saw a fellow
officer in physical trouble and decided to assist the other officer using minimal force.
The majority is far off the mark in finding this a violation of the Constitution. Their
ruling is both against the law and dangerous to law enforcement.
At the very least, clearly established law is not to the contrary. The majority
relies on two cases to affirm the district court, but both are distinguishable from the
“specific context” of this case. See Mullenix v. Luna, 577 U.S. 7, 12 (2015). The
first, Rice, relied on the fact that the late-arriving officers “did not observe [the
suspect] yell or use profanity,” were present for over a minute before the encounter
turned physical, and had spoken with an officer on the scene who explained to them
that the situation was not an emergency. See 989 F.3d at 1122–23. The officer in
the second case, Shafer v. County of Santa Barbara, 868 F.3d 1110 (9th Cir. 2017),
did not even arrive late to the scene—he initiated the interaction with the suspect
and escalated it to a physical confrontation. See id. at 1113, 1116.
3
Because it is “beyond debate” that Deputy Thomas acted reasonably based on
his limited knowledge, I would reverse the district court’s denial of qualified
immunity to him as well. See Ashcroft v. al-Kidd, 563 U.S. 731, 741 (2011).
I respectfully dissent.
