This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
Before: PAEZ, NGUYEN, and FRIEDLAND, Circuit Judges.
Plaintiff-Appellees Derrick Sanderlin, Breanna Contreras, Pietro di Donato,
Adira Sharkey, and Vera Clanton (Plaintiffs)1 are individuals who attended protests
that took place in San Jose following the death of George Floyd in 2020.
Defendant-Appellants Jason Dwyer, Lee Tassio, Jonathan Marshall, and Juan
Avila (Defendants) are police officers who were on the scene responding to those
protests. Plaintiffs allege that during the protests, Defendants violated their
constitutional rights under the First and Fourth Amendments. Defendants moved
for summary judgment, asserting qualified immunity. As relevant here, the district
court denied qualified immunity to Defendant Dwyer as to the claims brought by
Plaintiffs Sanderlin, Contreras, di Donato, and Sharkey (Group Plaintiffs),2 and it
denied qualified immunity to Defendants Tassio, Marshall, and Avila as to the
claims brought by Plaintiff Clanton. We have jurisdiction under 28 U.S.C. 1291,
1
Both parties incorrectly assume that the claims of Plaintiff Joseph Stukes are at
issue in this appeal. Stukes brought 42 U.S.C. § 1983 claims only against
Defendant Edgardo Garcia, to whom the district court granted summary judgment
on all claims asserted against him on the ground that he could not be held liable as
a supervisor. Stukes has not brought a cross-appeal of this holding by the district
court. Accordingly, Stukes’s claims against Garcia are not the subject of this
appeal.

In the district court’s order, the “Group Plaintiffs” also included Plaintiff Cayla
Sanderlin. The Plaintiffs’ answering brief, however, does not defend any claim
asserted by Cayla Sanderlin, including her First Amendment claim that survived
summary judgment.

and we review de novo the district court’s denial of summary judgment. Hopson v.
Alexander, 71 F.4th 692, 697 (9th Cir. 2023). We reverse the district court’s denial
of qualified immunity to Dwyer, but we affirm as to the other Defendants.
1. Group Plaintiffs were each struck by a projectile fired by an unknown
officer (except for Sanderlin, who was struck by a projectile fired by Defendant
Michael Panighetti). 3 Group Plaintiffs assert First and Fourth Amendment claims
under 42 U.S.C. § 1983 against Defendant Dwyer, who served as the San Jose
Police Department’s (SJPD) Incident Commander in responding to the protests on
May 29, 2020—the day each of the Group Plaintiffs were struck. In this role,
Dwyer authorized two other SJPD officers, neither of whom are named as
defendants in this case, to use 37mm launchers as a crowd control technique after
the crowd failed to abide by dispersal orders. Group Plaintiffs argue that Dwyer
can be held liable as a supervisor for the alleged First and Fourth Amendment
violations they suffered because his authorization of the 37mm against the
protestors set in motion “the nature and extent of the SJPD showing of force,”
which ultimately resulted in them being struck by projectiles.
Group Plaintiffs’ claims against Dwyer as a supervisor fail as a matter of
law. Even assuming that Group Plaintiffs could demonstrate the requisite causal

Panighetti in a concurrently filed opinion.

connection to hold Dwyer liable for the alleged constitutional violations they
suffered, see Starr v. Baca, 652 F.3d 1202, 1207 (9th Cir. 2011), Dwyer would still
be entitled to qualified immunity because his actions did not violate clearly
established law.
Officers are entitled to qualified immunity “unless (1) they violated a federal
statutory or constitutional right, and (2) the unlawfulness of their conduct was
clearly established at the time.” Hopson, 71 F.4th at 697 (citation omitted). In
denying qualified immunity to Dwyer, the district court framed the question under
the second prong as “whether it was clearly established that an officer could not
shoot a projectile at an individual who was peacefully protesting,” and that
“[under] Group Plaintiffs’ version of events, the officers had notice that shooting
these Plaintiffs would be unconstitutional.” The district court erred by focusing the
“clearly established law” inquiry on the acts of the officers who struck Group
Plaintiffs, rather than on the acts of Dwyer himself.
Under Chavez v. United States, “a supervisor faces liability under the Fourth
Amendment only where ‘it would be clear to a reasonable [supervisor] that his
conduct was unlawful in the situation he confronted.’” 683 F.3d 1102, 1110 (9th
Cir. 2012) (quoting Saucier v. Katz, 533 U.S. 194, 202 (2001) (emphasis added)).
“[P]laintiffs cannot base a claim against supervisors on a theory of respondeat
superior, and must instead show that the supervisors, ‘through [their] own
4
individual actions, ha[ve] violated the Constitution.’” Id. at 1109 (quoting
Ashcroft v. Iqbal, 556 U.S. 662, 676 (2009)). Thus, to determine whether Dwyer is
entitled to qualified immunity, we ask not whether the officers who fired
projectiles at Group Plaintiffs knew that their actions were unconstitutional, but
instead whether clearly established law prohibited Dwyer from authorizing the use
of crowd control devices consistent with policy when confronted with a crowd that
was not abiding by dispersal orders. Group Plaintiffs have failed to identify any
authority that would have put a reasonable officer in Dwyer’s position on notice
that such authorization would violate clearly established law. The district court
therefore erred in denying qualified immunity to Dwyer.
2. We affirm the district court’s denial of qualified immunity to
Defendants Tassio, Avila, and Marshall. Plaintiff Clanton asserts that she was
roughly manhandled and slammed to the ground while the officers arrested her.
Resolving factual disputes and drawing inferences in Clanton’s favor, as we must
at this stage, the Defendants violated Clanton’s clearly established rights. Case
law from this court clearly establishes that a police officer violates the Fourth
Amendment when he grabs an individual suspected of a nonviolent offense, who
objects and passively resists, throws the individual to the ground, and twists that
individual’s arms while handcuffing them. Meredith v. Erath, 342 F.3d 1057,
1061 (9th Cir. 2003). The district court therefore appropriately denied Defendants
5
Tassio, Marshall, and Avila qualified immunity.
AFFIRMED in part, REVERSED in part, and REMANDED.
