Opinion by Judge Miller

SUMMARY *

Jurisdiction / Qualified Immunity

The panel dismissed for lack of jurisdiction an interlocutory appeal from an order denying a motion for summary judgment on the basis of qualified immunity in an action brought pursuant to 42 U.S.C. § 1983, state law, and the Americans with Disabilities Act by Adrian Rios and his two children against the City of Azusa, Los Angeles County, individual police officers, and a paramedic.

In the course of handcuffing Rios to take him into custody, officers twice used a Taser and repeatedly punched, kicked, or otherwise struck him, at least 24 times. Rios

suffered serious brain damage and is now in a persistent vegetative state.

The panel held that it lacked jurisdiction to review the district court’s decision not to exclude certain evidence as a discovery sanction. Under Johnson v. Jones, 515 U.S. 304 (1995), the court may not review a portion of a district court’s summary judgment order that, though entered in a qualified immunity case, determines only a question of evidence sufficiency. Because the crux of defendants’ argument was that the district court abused its discretion in denying their motion to strike a declaration, defendants raised only a question about evidence sufficiency that may not be reviewed in an interlocutory appeal.

The panel further rejected defendants’ contentions that pendent jurisdiction applied. Because the panel lacked jurisdiction to review the denial of qualified immunity, there was no appealable claim to which a pendent claim could attach. Accordingly, the panel dismissed the appeal in its entirety.

OPINION

MILLER, Circuit Judge:

In an interlocutory appeal from an order denying a motion for summary judgment on the basis of qualified immunity, we may consider “whether the facts establish a violation of a clearly established constitutional right.” Peck v. Montoya, 51 F.4th 877, 885 (9th Cir. 2022). But we may not review the district court’s assessment of the sufficiency of the evidence—“which facts a party may, or may not, be able to prove at trial.” Id. (quoting Johnson v. Jones, 515 U.S. 304, 313 (1995)). This case presents the question whether we may review a district court’s decision not to exclude certain evidence as a discovery sanction. We hold that we may not.

RIOS V. CITY OF AZUSA 5

Late in the evening of July 22, 2021, several callers reported to the Azusa, California, police that a man in the courtyard of an apartment complex was acting erratically. The callers said that the man was talking to himself and had threatened a shooting, but they gave conflicting accounts of whether he might be armed. Based on information provided by the building manager, a 911 dispatcher identified the man as Adrian Rios and determined that he was subject to a domestic-violence restraining order.

Several police officers arrived at the scene. Over the course of approximately half an hour, they observed Rios walk back and forth as he repeated the phrase, “bang, bang, shots fired,” while making the shape of a gun with his hands. Although some of the officers had a clear view of Rios and others did not, none saw him with a weapon. The officers ordered Rios to get on the ground, but he did not comply.

Some of the officers then approached Rios to take him into custody. The nature of the resulting interaction is disputed, but it is not disputed that in the course of handcuffing Rios, the officers twice used a Taser and repeatedly punched, kicked, or otherwise struck him—by their own description, at least 24 times. Rios suffered serious brain damage and is now in a persistent vegetative state.

Rios and his two children, Adrian Rios Jr. and M.P.R., brought this action against the City of Azusa, Los Angeles County, seven individual police officers, and a paramedic. They asserted excessive-force and other constitutional claims under 42 U.S.C. § 1983, various state-law tort claims, and claims under the Americans with Disabilities Act of 1990 (ADA), 42 U.S.C. § 12101.

During discovery, counsel for plaintiffs became aware that Michael Brown, a resident of the apartment complex 6 RIOS V. CITY OF AZUSA

where the incident took place, had filed a pro se complaint against the Azusa Police Department alleging excessive force in an unrelated episode. Counsel promptly interviewed Brown. During the interview, counsel realized that they had already spoken with Brown shortly after the July 2021 incident involving Rios. In that earlier conversation, Brown said that he had witnessed Rios’s beating, but he refused to identify himself or provide a detailed statement. This time, however, he was willing to do so. A few days before the close of discovery, plaintiffs supplemented their initial disclosures under Federal Rule of Civil Procedure 26(a), which had not mentioned Brown, to state that Brown was likely to have discoverable information.

Soon thereafter, plaintiffs provided defendants with a declaration by Brown, which they ultimately included as an exhibit to their summary-judgment papers. In the declaration, Brown stated that although Rios “moved his hands and arms like a gun and said words about a gun, it was easy to see that he did not have a gun.” He added that as the officers approached, Rios “did not move in any manner I would describe as a fighting stance or threat.” According to Brown, “[r]ather than threaten the officers in any way, . . . Rios lay down on his stomach in front of them,” and it appeared that “he was obeying their command to get down.” At that point, Brown said, the officers “proceeded to kick Mr. Rios repeatedly while he lay on the ground defenseless,” even though Rios “was not fighting back,” “did not reach for a taser or swing at the officers,” and “did not appear to be resisting in any way.” Thereafter, “[o]ne of the officers knelt on top of Mr. Rios near his head or neck.”

Defendants moved for summary judgment, arguing that the officers were entitled to qualified immunity on the excessive-force claim. Under the doctrine of qualified
