    SUMMARY**
    Civil Rights
    The panel reversed in part and affirmed in part the district
    court’s order denying summary judgment to defendants in an
    action brought pursuant to 
    42 U.S.C. § 1983
     and California
    law by a pretrial detainee who alleged that defendants
    violated his Fourteenth Amendment right to be safeguarded
    from injury and his state law right to medical care while in
    custody.
    After being arrested, plaintiff was detained in a temporary
    holding cell and left unattended for around half an hour,
    during which time he attempted suicide, causing permanent
    and severe injury. With his mother acting as guardian ad
    litem, plaintiff filed suit alleging, in part, that defendants
    were deliberately indifferent to his safety because they failed
    to take appropriate action after plaintiff’s mother had warned
    a police officer over the phone that plaintiff was suicidal.
    The panel held that defendant Officer Brice was entitled
    to qualified immunity as a matter of law because a
    reasonable officer would not have known that failing to
    attend to plaintiff immediately after the phone call would be
    unlawful under the law at the time of the incident. The panel
    therefore reversed the district court’s denial of summary
    judgment in favor of Officer Brice on the § 1983 claim.

    The panel next held that it lacked jurisdiction to review
    the district court’s denial of summary judgment in favor of
    the municipal defendants on the § 1983 claim. The panel
    noted that when a municipal defendant’s motion for summary
    judgment is “inextricably intertwined” with issues presented
    in the individual officers’ qualified immunity appeal, this
    court may exercise pendent party appellate jurisdiction. The
    panel held that in this case appellate resolution of the
    officer’s appeal did not “necessarily” resolve the pendent
    claim of municipal liability. The panel noted that its holding
    that Officer Brice was entitled to qualified immunity did not
    preclude the possibility that a constitutional violation may
    nonetheless have taken place, including as a result of the
    collective acts or omissions of Santa Maria Police
    Department officers. The panel remanded to permit the
    district court to consider the claims in light of this court’s
    recent guidance in Castro v. County of Los Angeles, 
    833 F.3d 1060
     (9th Cir. 2016) (en banc), and Gordon v. County of
    Orange, 
    888 F.3d 118
    , 1125–26 (9th Cir. 2018).
    Finally, the panel affirmed the district court’s denial of
    summary judgment to defendants on the state law claim
    brought pursuant to California Government Code § 845.6,
    concluding that there was a genuine issue of material fact as
    to liability under state law.
    Dissenting in part, Judge Bybee joined the majority’s
    holding that Office Brice was entitled to qualified immunity
    for plaintiff’s deliberate-indifference claim under 
    42 U.S.C. § 1983
     and that the panel lacked jurisdiction over the
    municipal liability claim. Judge Bybee would have reversed
    the district court’s denial of summary judgment on the state
    law claim, because he believed that there was no basis under
    California law for subjecting Officer Brice to suit.

    OPINION
    BERZON, Circuit Judge:
    This case concerns the attempted suicide of a jailed
    pretrial detainee. Shane Horton was arrested for slashing an
    acquaintance’s car tire and taken to the local police
    department, where he was detained in a temporary holding
    cell. Left unattended for around half an hour while the officer
    in charge spoke to his mother and completed paperwork,
    Horton removed his belt, fed it through the cell door bars, and
    hanged himself, causing permanent and severe brain damage.
    With his mother acting as guardian ad litem, Horton
    brought suit under 
    42 U.S.C. § 1983
     and California law. He
    contends that the City of Santa Maria, the Santa Maria Police
    Department, and several individual officers violated his
    Fourteenth Amendment right to be safeguarded from injury
    HORTON V. CITY OF SANTA MARIA                    5
    and his state law right to medical care while in custody. We
    reverse the district court’s denial of qualified immunity on the
    § 1983 claims as to Officer Andrew Brice, conclude that we
    lack jurisdiction to review the denial of summary judgment
    on the § 1983 claims as to the municipal defendants, and
    affirm the district court’s denial of summary judgment on the
    state law claims.
    I. Factual and Procedural History
    In the months leading up to his arrest, eighteen-year-old
    Horton had given his mother reason to be concerned. He
    used drugs, including marijuana, “Molly” (a pure form of 3,4-
    Methylenedioxymethamphetamine), and phencyclidine
    (PCP), and contemplated suicide. On December 13, 2012, he
    took PCP and “started freaking out.” He extinguished
    cigarettes on his own face and hands, punched his fist through
    a window, tried to cut his wrist with a piece of broken glass,
    held a kitchen knife pointed at his throat, and, his mother
    understood, threatened to kill himself. That night, he was
    admitted to the emergency room, where he was initially held
    as a suicide risk. But he specifically denied to hospital staff
    any suicidal ideation, and the doctors came to suspect “that
    [his problem] was mostly drugs.” Horton was discharged the
    morning of December 14, 2012, after an emergency room
    physician and a member of the county’s Crisis and Recovery
    Emergency Services (“CARES”) team agreed that he was not
    suicidal.
    Approximately two weeks later, on the morning of
    December 29, 2012, Horton and his girlfriend became
    involved in a physical altercation. As his girlfriend was
    driving away with a friend, Horton pulled out a folding knife
    and slashed the tire of the friend’s car.
    6           HORTON V. CITY OF SANTA MARIA
    Officers Andrew Brice and Duane Schneider soon arrived
    on the scene and found Horton. Horton admitted to slashing
    the tire, pointed the police to the knife, and remained calm
    and cooperative as the officers arrested him for misdemeanor
    vandalism.
    Officer Brice stayed to interview Horton’s girlfriend. She
    disclosed that Horton had hit her several times in the past,
    chased her with a knife, and stabbed a friend in the leg. She
    also revealed that he had made comments about killing police
    and sympathizing with the suspects in recent mass homicides.
    While Officer Brice was speaking to Horton’s girlfriend,
    Officer Schneider transported Horton to the police station,
    where he patted Horton down, confiscated his wallet and
    iPod, and placed him in a temporary holding cell. Officer
    Schneider did not remove Horton’s jewelry or belt. As
    Officer Schneider prepared to leave, Horton said he was
    feeling anxious and “would really like to speak to someone”
    — “not a therapist. Even you.” As they talked, Horton
    explained to Officer Schneider that it had been “a really,
    really, really rough three weeks straight.” He described his
    recent drug use and the window-breaking incident, and said
    that he “had the shit beat out of me fucking thousands of
    times.” At one point, Officer Schneider asked if he had any
    medical problems; Horton responded, “No, sir. Not that I
    know of. I’m real healthy as I’m aware. I’m just — besides
    feeling anxious right now and I hate being locked in a box
    . . . . I don’t like being in a cell.”
    HORTON V. CITY OF SANTA MARIA                          7
    Eventually, Officer Schneider left, stating that he would
    “[p]robably do a psych or something.”1 He instructed Horton
    to wave at the security camera if he needed anything. A few
    minutes later, another police officer asked Horton if he had
    any medical problems; Horton again said he did not.
    Approximately an hour and a half later, Officer Brice
    returned to the police station. Officer Brice spoke to Horton
    privately in an interview room, explaining that Horton’s
    girlfriend and her friend both said that Horton slapped the
    girlfriend, and reporting that she had a mark on her consistent
    with that allegation. Officer Brice said that Horton’s
    girlfriend had been granted a restraining order against him for
    one week, that he would be charged with felony domestic
    violence, and that he had the option to post bail. At one point
    during the conversation, Officer Brice asked Horton if he had
    any medical conditions, and Horton once again replied, “No,
    sir.”
    At the end of the interview, Officer Brice brought Horton
    back to the holding cell and gave him the opportunity to call
    his mother, Yvonne Horton.2 Horton told his mother, “I’m in
    jail right now. I’m going to get booked and go to [the main
    county jail in] Goleta. You can choose to be there, get me out
    on bail or not. . . . I would appreciate it [if you came to get
    me out on bail], but it is up to you.” Yvonne apparently said
    she would not bail him out, and he ended the conversation by
    saying, “It’s okay, Mom. I’m sorry . . . . All right. I love
    1
    Officer Schneider presumably meant that he was considering
    ordering a psychiatric evaluation of Horton.

    son.
    8               HORTON V. CITY OF SANTA MARIA
    you.” Before hanging up, Yvonne requested to speak
    privately to Officer Brice.
    Officer Brice left Horton in the cell and, out of Horton’s
    earshot, called Yvonne back. Officer Brice spoke with
    Yvonne for ten to fifteen minutes, during which time, she
    stated in her deposition, she relayed “everything” about the
    December 13, 2012 incident — Horton’s use of drugs, the
    cigarette marks on his face and hands, the knife he held to his
    throat, his hospitalization with an initial “5150” hold for risk
    of suicide,3 the CARES official’s conclusion that he could be
    discharged because his conduct was due to drugs not suicidal
    ideation, and her disagreement with that conclusion. Yvonne
    testified that she also told Officer Brice that her son was
    depressed and suicidal, that she was really worried about him,
    and that she believed he could be helped in the judicial
    system. And she recounted that she instructed Officer Brice
    to “please, watch him, please look after him, please.”4

    California Welfare and Institutions Code § 5150 authorizes qualified
    officers or clinicians to involuntarily take into custody a person who, “as
    a result of a mental health disorder, is a danger to others, or to himself or
    herself, or gravely disabled.” 
    Cal. Welf. & Inst. Code § 5150
    .
    4
    Officer Brice denies that Yvonne ever used the terms “suicidal” or
    “tried to kill himself.” He testified that Yvonne instead told him that
    CARES declined to keep Horton “because they believed his actions were
    drug induced,” which she was upset about, and that she was equivocating
    on whether to bail him out, because she felt her son would be safer in jail
    than out. However, in deciding this qualified immunity interlocutory
    appeal, we rely on the record as most favorable to Horton, see Saucier v.
    Katz, 
    533 U.S. 194
    , 201 (2001), overruled in part on other grounds by
    Pearson v. Callahan, 
    555 U.S. 223
    , 236 (2009), and so disregard Officer
    Brice’s testimony to the extent it contradicts that of Yvonne.
    HORTON V. CITY OF SANTA MARIA                           9
    Officer Brice explained to Yvonne that he was getting
    ready to transport Horton to jail, which Yvonne understood
    to mean that they would be transporting him “very shortly.”
    In response to Yvonne’s pleas to look after her son, Officer
    Brice reassured her that “[h]e’s safe here.” When asked at
    deposition whether she ever told the police officer he had to
    go check on Horton immediately, she said, “I didn’t think that
    I would have to do that. . . . I was under the impression, after
    I spoke to [him] in that way, that he would go back and check
    on him.”
    Instead of going immediately back to the cell, Officer
    Brice first went to complete the paperwork necessary to
    transport Horton to jail and prepare the transport van. When
    Officer Brice went to get Horton, approximately 27 minutes
    after leaving him,5 Officer Brice discovered Horton hanging
    from the cell door, not moving. Officer Brice immediately
    called for assistance, administered CPR, and waited for the
    paramedics to arrive to transport him to the hospital. Horton
    survived the suicide attempt but suffered prolonged anoxia,6
    resulting in severe and permanent brain damage.
    5
    As previously noted, Officer Brice’s conversation with Horton’s
    mother lasted for approximately ten to fifteen minutes. In the first few
    minutes of that conversation, Horton removed the belt he was wearing,
    strung it through the cell door bars, looped it around his neck, and
    slumped down. Approximately eight minutes before the phone call ended,
    Horton was no longer seen moving in the security camera video. Another
    twelve to seventeen minutes elapsed after the call ended before Officer
    Brice returned to Horton’s cell and found him hanging.

    Anoxia refers to a restriction in oxygen flow to the brain. The
    longer the period of oxygen deprivation, the more severe the brain damage
    and “the lower the chances of a full or meaningful recovery.” Daniels v.
    Woodford, 
    428 F.3d 1181
    , 1194 n.18 (9th Cir. 2005).
    10           HORTON V. CITY OF SANTA MARIA
    With his mother acting as guardian ad litem, Horton filed
    suit in October 2014 against the City of Santa Maria, the
    Santa Maria Police Department, Officer Brice, Officer
    Schneider, and other officers, claiming (1) negligence and
    (2) § 1983 liability on the part of the individual officer
    defendants, (3) liability on the part of the municipal
    defendants, see Monell v. Dep’t of Soc. Servs., 
    436 U.S. 658
    (1978), and (4) liability under California Government Code
    § 845.6 on the part of all defendants.
    The district court granted summary judgment to all
    defendants on the state law negligence claim and to all
    officers except Officer Brice on the § 1983 claims. As to
    Officer Brice, the district court held that there is a genuine
    issue of fact regarding whether Officer Brice acted with
    deliberate indifference to Horton’s safety after speaking with
    his mother, and denied him qualified immunity. The court
    also denied summary judgment to the municipal defendants
    on Horton’s § 1983 claim that those defendants failed to
    develop and adhere to a written policy regarding suicide
    detection and prevention; failed to develop and adhere to
    written policies regarding the identification and evaluation of
    mentally disordered detainees; and failed adequately to train
    their officers on such policies. Finally, the district court
    denied summary judgment to Officer Brice and the municipal
    defendants on the claim under California Government Code
    § 845.6, but granted summary judgment on that claim to the
    other individual officers. Officer Brice and the municipal
    defendants timely appealed. See Mitchell v. Forsyth,
    
    472 U.S. 511
    , 530 (1985).

    II. Discussion
    A. Section 1983 Claim Against Officer Brice
    The district court concluded that there is a genuine issue
    of fact regarding whether Officer Brice acted with deliberate
    indifference to Horton’s safety after speaking with his
    mother, and denied the officer qualified immunity. Qualified
    immunity protects government officials from liability for civil
    damages unless their conduct violates “clearly established
    statutory or constitutional rights of which a reasonable person
    would have known.” Harlow v. Fitzgerald, 
    457 U.S. 800
    ,
    818 (1982). Plaintiffs bringing § 1983 claims against
    individual officers therefore must demonstrate that (1) a
    federal right has been violated and (2) the right was clearly
    established at the time of the violation. Pearson v. Callahan,
    
    555 U.S. 223
    , 232 (2009). We may “exercise [our] sound
    discretion in deciding which of the two prongs of the
    qualified immunity analysis should be addressed first.” 
    Id. at 236
    . Here, we begin with the second, “clearly established”
    prong, for reasons that will appear.
    1. Clearly Established Law
    “A clearly established right is one that is sufficiently clear
    that every reasonable official would have understood that
    what he is doing violates that right.” Isayeva v. Sacramento
    Sheriff’s Dep’t, 
    872 F.3d 938
    , 946 (9th Cir. 2017) (quoting
    Mullenix v. Luna, 
    136 S. Ct. 305
    , 308 (2015)). At the time of
    the events in this case, the generally applicable standard
    established that officers who act with deliberate indifference
    to the serious medical need of a pretrial detainee violated the
    detainee’s constitutional rights under the Due Process Clause
    of the Fourteenth Amendment. See, e.g., Conn v. City of
    12           HORTON V. CITY OF SANTA MARIA
    Reno, 
    591 F.3d 1081
    , 1090–91 (9th Cir. 2010), vacated,
    
    563 U.S. 915
     (2011), opinion reinstated in relevant part,
    
    658 F.3d 897
     (9th Cir. 2011).
    Under Ninth Circuit law at the time of the incident,
    Fourteenth Amendment claims that officers acted with
    deliberate indifference to the medical needs of a pretrial
    detainee were governed by the same “deliberate indifference”
    standard as Eighth Amendment claims for failure to prevent
    harm to convicted prisoners. See Simmons v. Navajo County,
    
    609 F.3d 1011
    , 1017 (9th Cir. 2010), overruled in part by
    Castro v. County of Los Angeles, 
    833 F.3d 1060
     (9th Cir.
    2016) (en banc); Clouthier v. County of Contra Costa,
    
    591 F.3d 1232
    , 1241–43 (9th Cir. 2010), overruled by Castro,
    
    833 F.3d 1060
    . That standard provided that an officer was
    liable for deliberate indifference only if he “kn[ew] of and
    disregard[ed] an excessive risk to inmate health or safety” —
    that is, if he was “aware of facts from which the inference
    could be drawn that a substantial risk of serious harm exists”
    and actually drew the inference. Simmons, 
    609 F.3d at 1017
    (quoting Farmer v. Brennan, 
    511 U.S. 825
    , 837 (1994)).
    “Deliberate indifference thus require[d] an objective risk of
    harm and a subjective awareness of that harm.” Conn,
    
    591 F.3d at 1095
    . (As we shall explain, that partially
    subjective standard has since been revised to an entirely
    objective standard for pretrial detainees. See Gordon v.
    County of Orange, 
    888 F.3d 1118
    , 1125–26 (9th Cir. 2018);
    Castro, 833 F.3d at 1068–71; infra pp. 16–18).
    Two principles inform our clearly established law inquiry
    in this case. First, the qualified immunity inquiry “must be
    undertaken in light of the specific context of the case, not as
    a broad general proposition.” Saucier, 533 U.S. at 201; see
    also Ashcroft v. al-Kidd, 
    563 U.S. 731
    , 742 (2011) (“We have
    HORTON V. CITY OF SANTA MARIA                     13
    repeatedly told courts . . . not to define clearly established law
    at a high level of generality.”). It is therefore critical whether
    our case law had, at the time of the events in this case,
    sufficiently clarified when a detainee’s imminent risk of
    suicide was substantial enough to require immediate
    attention.
    Second, in Estate of Ford v. Ramirez-Palmer, we
    recognized that deliberate indifference claims “depend in part
    on a subjective test that does not fit easily with the qualified
    immunity inquiry,” which is an objective inquiry. 
    301 F.3d 1043
    , 1049 (9th Cir. 2002). Estate of Ford concluded that
    even where the clearly established legal standard requires
    deliberate indifference, the qualified immunity inquiry should
    concentrate on the objective aspects of the constitutional
    standard. That is because “a reasonable prison official
    understanding that he cannot recklessly disregard a
    substantial risk of serious harm, could know all of the facts
    yet mistakenly, but reasonably, perceive that the exposure in
    any given situation was not that high.” 
    Id. at 1050
    . We held
    that “[i]n these circumstances, [an officer] would be entitled
    to qualified immunity” under the deliberate indifference
    standard. 
    Id.
    Thus, Horton must show that, given the available case law
    at the time of his attempted suicide, a reasonable officer,
    knowing what Officer Brice knew, would have understood
    that failing to check on Horton immediately after the phone
    call with Yvonne presented such a substantial risk of harm to
    Horton that the failure to act was unconstitutional. We turn to
    the directly applicable case law now, which is sparse.
    At the time of Horton’s incident, we had held that officers
    who failed to provide medical assistance to a detainee should
    14             HORTON V. CITY OF SANTA MARIA
    have known that their conduct was unconstitutional in two
    instances, neither of which resemble the facts in this case.
    See Clouthier, 
    591 F.3d at
    1244–45; Conn, 
    591 F.3d at 1098
    .
    Clouthier held that a mental health specialist who failed
    to take adequate precautions to protect a detainee from
    committing suicide was not entitled to qualified immunity.
    
    591 F.3d at 1245
    . The specialist knew that the detainee was
    suicidal, that he had attempted suicide multiple times, and
    that another staff member had placed the detainee in a suicide
    smock and warned that he needed to be “constantly
    monitored throughout the day to ensure his safety.” 
    Id. at 1244
    . Nevertheless, the specialist removed the detainee from
    regular suicide monitoring and instructed officers to return
    his regular clothes and bedding, which he eventually used to
    commit suicide. 
    Id. at 1245
    . Under these facts, we
    concluded that “a reasonable mental health professional could
    not have thought it was lawful to remove key suicide
    prevention measures put in place by a prior Mental Health
    staff member.” Id.7
    In Conn, we denied qualified immunity at the summary
    judgment stage to officers who, while transporting a detainee,
    observed her wrap a seatbelt around her neck in an apparent
    attempt to choke herself and who threatened to commit
    suicide. 
    591 F.3d at 1098
    . The transporting officers did not
    take the detainee to a medical center or alert subsequent
    7
    Clouthier also held that a prison deputy’s knowledge of the
    detainee’s past suicide attempts and present suicidal tendency was
    “insufficient to allow a jury to conclude that [the deputy] knew Clouthier
    was suicidal and deliberately ignored that risk.” 
    591 F.3d at 1247
    . Because
    that holding was on the subjective knowledge prong of the deliberate
    indifference standard, it is not directly relevant to Estate of Ford’s
    objective reasonable official inquiry.
    HORTON V. CITY OF SANTA MARIA                            15
    officers to the behavior; she then committed suicide. 
    Id.
     We
    concluded that “[w]hen a detainee attempts or threatens
    suicide en route to jail, it is obvious that the transporting
    officers must report the incident to those who will next be
    responsible for her custody and safety.” Id. at 1102.8
    The facts of Clouthier and Conn do not at all resemble
    this case. Officer Brice’s interactions with Horton began with
    his initial arrest, during which Horton remained cooperative.
    Officer Brice also spoke with Horton’s girlfriend, who
    informed him of Horton’s previous violent episodes, but did
    not indicate any present suicidal intentions. At the jail,
    Officer Brice asked Horton if he was having any medical
    problems, to which Horton responded in the negative.
    Officer Brice did know that Horton, according to his
    mother, had been suicidal two weeks before the incident and
    that his mother thought he remained a suicide risk.
    Based on these facts, which are taken in the light most
    favorable to Horton, a reasonable officer would not have
    known that failing to attend to Horton immediately would be
    unlawful under the law at the time of the incident. Horton did
    not attempt suicide in the presence of Officer Brice, as the
    detainee did in Conn. 
    591 F.3d at 1102
    . Nor, as was the case
    in Clouthier, had he attempted suicide multiple times and
    been deemed such a risk that medical specialists placed
    8
    While Conn did not cite expressly to Estate of Ford, it did cite to
    Clouthier and did apply an objective test. See Conn, 
    591 F.3d at 1102
    (“The relevant, dispositive inquiry in determining whether a right is
    clearly established is whether it would be clear to a reasonable officer that
    his conduct was unlawful in the situation he confronted.” (quoting
    Saucier, 533 U.S. at 202)).
    16              HORTON V. CITY OF SANTA MARIA
    significant suicide prevention measures in place, measures
    removed by the defendant. 
    591 F.3d at 1245
    . In short,
    whether or not Officer Brice was in fact deliberately
    indifferent to a substantial risk that Horton would attempt
    suicide in the time before he was checked, there was no case
    law at the time of the incident clearly establishing that a
    reasonable officer should have perceived the substantial risk.9
    In short, applying Estate of Ford, the case law at the time
    of Horton’s attempted suicide was simply too sparse, and
    involved circumstances too distinct from those in this case, to
    establish that a reasonable officer would perceive a
    substantial risk that Horton would imminently attempt
    suicide. We therefore reverse the district court’s denial of
    summary judgment on qualified immunity as to Officer Brice.
    2. The Current Deliberate Indifference Standard
    Since the incident in this case took place, this court has
    announced a new liability standard governing Fourteenth
    Amendment failure-to-protect claims by pretrial detainees.
    Castro v. County of Los Angeles held that, in light of the
    Supreme Court’s decision in Kingsley v. Hendrickson, 
    135 S. Ct. 2466
     (2015), Fourteenth Amendment failure-to-protect
    9
    Nor was there law at the time in other courts clearly establishing that
    a reasonable officer would have known that failing to immediately check
    up on Horton would have been unlawful. “In the absence of binding
    precedent, we look to whatever decisional law is available to ascertain
    whether the law is clearly established for qualified immunity purposes,
    including decisions of state courts, other circuits, and district courts.”
    Boyd v. Benton County, 
    374 F.3d 773
    , 781 (9th Cir. 2004) (citation and
    internal quotation marks omitted). We have not found other cases applying
    the objective qualified immunity inquiry prescribed by Estate of Ford to
    facts similar to Horton’s case.
    HORTON V. CITY OF SANTA MARIA                    17
    claims must be analyzed under a purely objective standard.
    Castro, 833 F.3d at 1068–71. Under Castro, we ask whether
    there was “a substantial risk of serious harm to the plaintiff
    that could have been eliminated through reasonable and
    available measures that the officer did not take, thus causing
    the injury that the plaintiff suffered.” Id. at 1070. There is no
    separate inquiry into an officer’s subjective state of mind.
    We have recently recognized that Castro’s objective
    deliberate indifference standard extends to Fourteenth
    Amendment claims by pretrial detainees for violations of the
    right to adequate medical care. See Gordon, 888 F.3d at
    1125–26. This objective standard would therefore guide our
    analysis of whether a constitutional violation occurred here,
    were we to reach that question. But it has no direct bearing
    on the question of whether Officer Brice would have known
    that a failure to immediately check on Horton violated a
    clearly established right at the time of the incident.
    As the pre-Castro standard is no longer applicable, no
    purpose would be served for future cases from delineating the
    application of that standard to the constitutional merits of this
    case. The two-step qualified immunity procedure “is
    intended to further the development of constitutional
    precedent,” and we may decide “whether that procedure is
    worthwhile in particular cases.” Pearson, 
    555 U.S. at 237, 242
    . We therefore tend to address both prongs of qualified
    immunity where the “‘two-step procedure promotes the
    development of constitutional precedent’ in an area where
    this court’s guidance is . . . needed.” Mattos v. Agarano, 
    661 F.3d 433
    , 440 (9th Cir. 2011) (en banc) (quoting Pearson,
    
    555 U.S. at 236
    ); see also Thompson v. Rahr, 
    885 F.3d 582
    ,
    590 (9th Cir. 2018) (determining that a constitutional
    violation occurred before holding that the officer was entitled
    18           HORTON V. CITY OF SANTA MARIA
    to qualified immunity so that “[g]oing forward, . . . the law is
    clearly established in this scenario”). Here, Castro and
    Gordon have established the law going forward, and further
    delineation of the pre-Castro standard would serve little
    purpose, as it is no longer applicable. We therefore confine
    our inquiry to the second qualified immunity prong —
    whether the constitutional right at issue was “clearly
    established” at the time of the alleged violation.
    B. Section 1983 Claim Against Municipal Defendants
    As to the denial of summary judgment in favor of the
    municipal defendants on Horton’s § 1983 claims, we lack
    jurisdiction over the municipal defendants’ appeal of that
    order.
    Monell established that municipalities can be liable for
    infringement of constitutional rights, under certain
    circumstances. 
    436 U.S. at
    690–95. In particular,
    municipalities may be liable under § 1983 for constitutional
    injuries pursuant to (1) an official policy; (2) a pervasive
    practice or custom; (3) a failure to train, supervise, or
    discipline; or (4) a decision or act by a final policymaker. A
    municipality may not, however, be sued under a respondeat
    superior theory. Id. at 693–95. A plaintiff must therefore
    show “deliberate action attributable to the municipality [that]
    directly caused a deprivation of federal rights.” Bd. of Cty.
    Comm’rs v. Brown, 
    520 U.S. 397
    , 415 (1997). “Where a
    court fails to adhere to rigorous requirements of culpability
    and causation, municipal liability collapses into respondeat
    superior liability.” 
    Id.
    Although the requisites for municipal liability under
    § 1983 can be stringent, municipalities sued under § 1983,
    HORTON V. CITY OF SANTA MARIA                             19
    unlike individuals, are not entitled to immunity, qualified or
    otherwise, and so, unlike individuals, can never be immune
    from trial.10 The denial of summary judgment to a municipal
    defendant on a Monell claim is therefore no different from the
    denial of any ordinary motion for summary judgment, and so
    is not immediately appealable. See Collins v. Jordan,
    
    110 F.3d 1363
    , 1366 n.1 (9th Cir. 1996); Henderson v.
    Mohave County, 
    54 F.3d 592
    , 594 (9th Cir. 1995).
    There is, however, one caveat to this rule. When a
    municipal defendant’s motion for summary judgment is
    “inextricably intertwined” with issues presented in the
    individual officers’ qualified immunity appeal, this court may
    exercise pendent party appellate jurisdiction. See Huskey v.
    City of San Jose, 
    204 F.3d 893
    , 903–05 (9th Cir. 2000). In
    this context, the “inextricably intertwined” concept is a
    narrow one. “[A] pendent appellate claim can be regarded as
    inextricably intertwined with a properly reviewable claim on
    collateral appeal only if the pendent claim is coterminous
    10
    The collateral order doctrine allows for appeals from a narrow
    category of interlocutory orders that do not fully resolve an action. See
    Cohen v. Beneficial Indus. Loan Corp., 
    337 U.S. 541
    , 545–47 (1949)
    (holding that certain interlocutory decisions could be final for purposes of
    
    28 U.S.C. § 1291
    ). Denials of qualified immunity are among that
    category. The qualified immunity defense shields government officials
    from the costs and distractions of litigation and not just from liability. See
    Mitchell, 
    472 U.S. at 526
     (holding that the denial of qualified immunity
    is immediately appealable, as officials enjoy “an entitlement not to stand
    trial or face the other burdens of litigation, conditioned on the resolution
    of the essentially legal question whether the conduct of which the plaintiff
    complains violated clearly established law”). Therefore, even though
    appellate review of a denial of qualified immunity would be possible after
    a final judgment, immediate appeal is permitted to protect the right of
    officials to be free from the burdens of litigation. Municipalities do not
    enjoy any parallel right to be shielded from such burdens.
    20           HORTON V. CITY OF SANTA MARIA
    with, or subsumed in, the claim before the court on
    interlocutory appeal — that is, when the appellate resolution
    of the collateral appeal necessarily resolves the pendent claim
    as well.” Id. at 905 (citation omitted). Here, appellate
    resolution of the collateral appeal does not “necessarily”
    resolve the pendent claim, for several reasons.
    First, as we have explained, our qualified immunity
    determination with respect to Officer Brice rests solely on the
    “clearly established” law prong; we do not reach the question
    of whether Officer Brice’s actions gave rise to a
    constitutional violation. “[A] municipality may be liable if an
    individual officer is exonerated on the basis of the defense of
    qualified immunity, because even if an officer is entitled to
    immunity a constitutional violation might still have
    occurred.” Gibson v. County of Washoe, 
    290 F.3d 1175
    , 1186
    n.7 (9th Cir. 2002), overruled on other grounds by Castro,
    
    833 F.3d 1060
    . That is, the district court could still conclude
    that Officer Brice did commit a constitutional violation under
    the now-applicable standard and, if the other requisites of
    Monell liability are met, hold the municipality liable.
    Second, although the district court granted summary
    judgment in favor of the individual defendants other than
    Officer Brice on the ground that there was insufficient
    evidence they committed a constitutional violation, the
    district court could reconsider those summary judgments in
    light of the new, purely objective standard for Fourteenth
    Amendment failure-to-protect claims, which we announced
    after the district court issued its order. See Castro, 833 F.3d
    at 1068–70. Further, the district court’s grants of summary
    judgment as to the individual officers other than Officer Brice
    were not appealable, see 
    28 U.S.C. § 1291
    ; Way v. County of
    Ventura, 
    348 F.3d 808
    , 810 (9th Cir. 2003), and therefore
    HORTON V. CITY OF SANTA MARIA                             21
    cannot be assumed to be correct. As a result, the district court
    could conclude that municipal constitutional violations
    occurred involving the actions of officers other than Officer
    Brice.
    Third, municipal defendants may be liable under § 1983
    even in situations in which no individual officer is held liable
    for violating a plaintiff’s constitutional rights. As we have
    previously acknowledged, constitutional deprivations may
    occur “not . . . as a result of actions of the individual officers,
    but as a result of the collective inaction” of the municipal
    defendant. Fairley v. Luman, 
    281 F.3d 913
    , 917 (9th Cir.
    2002). “If a plaintiff establishes he suffered a constitutional
    injury by the City, the fact that individual officers are
    exonerated is immaterial to liability under § 1983,” regardless
    of whether their exoneration is “on the basis of qualified
    immunity, because they were merely negligent, or for other
    failure of proof.” Id. at 917 & n.4.11 Here, a reasonable jury
    11
    Other circuits apply the same principle in Monell cases. See Barrett
    v. Orange Cty. Human Rights Comm’n, 
    194 F.3d 341
    , 350 (2d Cir. 1999)
    (“[M]unicipal liability for constitutional injuries may be found to exist
    even in the absence of individual liability, at least so long as the injuries
    complained of are not solely attributable to the actions of named
    individual defendants.”); Fagan v. City of Vineland, 
    22 F.3d 1283
    , 1292
    (3d Cir. 1994) (“[A]n underlying constitutional tort can still exist even if
    no individual police officer violated the Constitution. . . . If it can be
    shown that the plaintiff suffered [an] injury, which amounts to deprivation
    of life or liberty, because the officer was following a city policy reflecting
    the city policymakers’ deliberate indifference to constitutional rights, then
    the City is directly liable under section 1983 for causing a violation of the
    plaintiff’s Fourteenth Amendment rights.”); Anderson v. City of Atlanta,
    
    778 F.2d 678
    , 686 (11th Cir. 1985) (“Monell . . . and its progeny do not
    require that a jury must first find an individual defendant liable before
    imposing liability on local government.”); Garcia v. Salt Lake County,
    
    768 F.2d 303
    , 310 (10th Cir. 1985) (“Monell does not require that a jury
    22             HORTON V. CITY OF SANTA MARIA
    might be able to conclude that Horton suffered a
    constitutional deprivation “as a result of the collective
    inaction” of the Santa Maria Police Department, id. at 917, or
    of officers’ adherence to departmental customs or practices,
    see, e.g., Tsao v. Desert Palace, Inc., 
    698 F.3d 1128
    , 1143
    (9th Cir. 2012); Long v. County of Los Angeles, 
    442 F.3d 1178
    , 1185–86 (9th Cir. 2006).
    For example, taking the facts in the light most favorable
    to the plaintiff, a jury might find that the Santa Maria Police
    Department failed to ensure compliance with its written
    policy of removing belts from detainees. The department’s
    policy manual indicated that arresting or booking officers
    “should” remove jackets, belts, and shoes. But, according to
    Officer Schneider, the “should” was understood to be
    optional and, before December 29, 2012, when the incident
    occurred, the usual practice was not to remove belts. An
    independent audit of the Santa Maria Police Department,
    conducted shortly before the incident for unrelated reasons,
    confirmed that “many SMPD members had only a passing
    knowledge of Department policies,” and that custody
    practices were “loose.”
    Second, a reasonable jury might find that the Police
    Department failed to assure proper monitoring of its security
    cameras. Officer Schneider twice told Horton that, if he
    needed anything, he could simply wave at the security
    cameras and an officer would come over. But no officer
    apparently observed Horton looping his belt through the cell
    door and hanging from it for over twenty minutes before
    Officer Brice returned to his cell.
    find an individual defendant liable before it can find a local governmental
    body liable.”).
    HORTON V. CITY OF SANTA MARIA                    23
    We do not decide whether any of these specific acts or
    omissions, or any other, if proven, would give rise to a
    municipal constitutional violation. Rather, our inquiry into
    the Monell claims at this stage is purely jurisdictional. For
    that purpose, we conclude that our holding that Officer Brice
    is entitled to qualified immunity does not preclude the
    possibility that a constitutional violation may nonetheless
    have taken place, including as a result of the collective acts or
    omissions of Santa Maria Police Department officers.
    In sum, the pendent Monell claim is not inextricably
    intertwined with a properly reviewable collateral appeal, as
    our resolution of Officer Brice’s appeal from the denial of
    summary judgment on qualified immunity does not
    “necessarily” resolve Horton’s Monell claim. Huskey,
    
    204 F.3d at 905
    . We therefore have no jurisdiction to review
    the denial of summary judgment as to the municipal
    defendants at this stage of the proceedings.
    C. State Law Claim Against All Defendants
    Finally, Officer Brice and the municipal defendants
    contend they are entitled to immunity on Horton’s state law
    claim. Under California law, prison officials generally cannot
    be sued for failing to provide medical care to a prisoner,
    unless the official knows, or reasonably should know, that the
    prisoner requires immediate medical care. California
    Government Code § 845.6 provides:
    Neither a public entity nor a public employee
    is liable for injury proximately caused by the
    failure of the employee to furnish or obtain
    medical care for a prisoner in his custody; but,
    except as otherwise provided by Sections
    24           HORTON V. CITY OF SANTA MARIA
    855.8 and 856, a public employee, and the
    public entity where the employee is acting
    within the scope of his employment, is liable
    if the employee knows or has reason to know
    that the prisoner is in need of immediate
    medical care and he fails to take reasonable
    action to summon such medical care.
    Cal. Gov’t Code § 845.6. Notably, under this statute, there is
    no analogue to the second prong of federal qualified
    immunity. Also, in contrast with Monell liability, California
    law allows for vicarious liability of a municipality whose
    employee violates the statute when acting within the scope of
    employment. See Cal. Gov’t Code § 815.2.
    The district court denied summary judgment to Officer
    Brice and the municipal defendants on Horton’s § 845.6
    claims, concluding that a reasonable jury could find that
    Officer Brice had reason to know Horton faced a substantial
    risk of attempting suicide and failed to take reasonable action
    to summon immediate medical care.
    One threshold matter: We have jurisdiction over the
    denial of summary judgment as to the state law claims. For
    state law immunity claims denied before trial, “the
    availability of an appeal depends on whether, under state law,
    the immunity functions as an immunity from suit or only as
    a defense to liability.” Liberal v. Estrada, 
    632 F.3d 1064
    ,
    1074 (9th Cir. 2011). “A denial of summary judgment is
    immediately appealable when the immunity is an immunity
    from suit . . .” 
    Id.
     Section 845.6 confers immunity from suit,
    not only from liability, on public entities and public
    employees for injuries caused by the failure to provide
    HORTON V. CITY OF SANTA MARIA                        25
    medical care. Castaneda v. Dep’t of Corr. & Rehab.,
    
    212 Cal. App. 4th 1051
    , 1070–71 (Ct. App. 2013).
    Reviewing the denial of summary judgment on the state
    law immunity issue de novo, see, e.g., Hansen v. Dep’t of
    Treasury, 
    528 F.3d 597
    , 600 (9th Cir. 2007), and construing
    the facts in the light most favorable to Horton, the nonmoving
    party, see Holmes v. Cal. Army Nat’l Guard, 
    124 F.3d 1126
    ,
    1131–32 (9th Cir. 1997), we hold that there is a genuine issue
    of material fact as to liability on the state law claims.
    “In order to state a claim under § 845.6, a prisoner must
    establish three elements: (1) the public employee knew or had
    reason to know of the need (2) for immediate medical care,
    and (3) failed to reasonably summon such care.” Jett v.
    Penner, 
    439 F.3d 1091
    , 1099 (9th Cir. 2006).
    Officer Brice and the municipal defendants offer several
    arguments for their immunity under § 845.6. First, they
    contend that Officer Brice’s alleged failure promptly to
    summon medical care is tantamount to a failure to diagnose,
    for which defendants are immune from liability under
    California Government Code § 855.8(a). See Cal. Gov’t
    Code § 845.6 (excepting from liability claims of injury
    resulting from diagnosing or failing to diagnose mental
    illness). We disagree. The scope of liability for the failure to
    summon medical care under § 845.6 is broader than the scope
    of immunity for the failure to diagnose, prescribe, or
    administer treatment under § 855.8.12 See Johnson v. County
    12
    California Government Code § 855.8 provides:
    (a) Neither a public entity nor a public employee acting
    within the scope of his employment is liable for injury
    26           HORTON V. CITY OF SANTA MARIA
    of Los Angeles, 
    143 Cal. App. 3d 298
    , 316–17 (Ct. App.
    1983); Nelson v. State, 
    139 Cal. App. 3d 72
    , 80–81 (Ct. App.
    1982). The complaint alleges that the defendants subjected
    Horton to “a delay in and/or denial of medical or mental
    health care,” not (or at least, not only) that they failed to
    diagnose or treat his mental illness — a responsibility
    typically entrusted to a medical professional. See Johnson,
    143 Cal. App. 3d at 316 (“We hold that as a matter of law a
    sheriff does not have the authority to make the final
    determination of diagnosing that a person is, or is not,
    afflicted with mental illness . . . . [S]uch determinations are
    properly made by physicians and other persons trained in the
    healing arts.”).
    Relatedly, the defendants argue that the exception to
    § 845.6’s broad immunity rule concerns the failure to
    resulting from diagnosing or failing to diagnose that a
    person is afflicted with mental illness or addiction or
    from failing to prescribe for mental illness or addiction.
    (b) A public employee acting within the scope of his
    employment is not liable for administering with due
    care the treatment prescribed for mental illness or
    addiction.
    (c) Nothing in this section exonerates a public
    employee who has undertaken to prescribe for mental
    illness or addiction from liability for injury proximately
    caused by his negligence or by his wrongful act in so
    prescribing.
    (d) Nothing in this section exonerates a public
    employee from liability for injury proximately caused
    by his negligent or wrongful act or omission in
    administering any treatment prescribed for mental
    illness or addiction.
    HORTON V. CITY OF SANTA MARIA                          27
    summon medical care, and Horton’s complaint centers on
    Officer Brice’s own failure to return immediately to Horton’s
    cell, rather than a failure to summon third-party medical care
    upon finding Horton. But Horton’s complaint is not so
    limited: It specifically alleges that defendants had reason to
    know that “Horton was in need of immediate medical care”
    and “failed to take reasonable action to summon such medical
    care.” Officer Schneider’s statement that they should
    “[p]robably do a psych,” indicates the kind of care that
    Officer Brice could have been expected to summon once he
    got off the phone with Yvonne.13 Had Officer Brice
    requested a prompt psychiatric evaluation or otherwise
    summoned psychiatric care, Horton could have been found
    sooner and the period of anoxia he suffered shortened. We
    cannot say, as a matter of law, that Officer Brice’s omissions
    did not proximately cause injury to Horton. See Zeilman,
    168 Cal. App. 3d at 1187.
    Finally, defendants maintain that Officer Brice did not
    know or have reason to know that Horton required immediate
    medical care. As to this proposition, two California Court of
    Appeal cases addressing § 845.6 claims premised on suicidal
    ideation are instructive. In Lucas v. City of Long Beach,
    
    60 Cal. App. 3d 341
     (Ct. App. 1976), the decedent hung
    himself in his cell after being arrested on charges of being
    drunk and disorderly. 
    Id.
     at 344–45. Reversing a jury verdict
    in favor of the plaintiff, the Court of Appeal emphasized that
    13
    There is little doubt that ordering a psychiatric evaluation could
    constitute “summoning medical care” under the California courts’ broad
    view of “medical care.” See Zeilman v. County of Kern, 
    168 Cal. App. 3d 1174
    , 1187 (Ct. App. 1985) (indicating that having medical personnel
    assist a pretrial detainee on crutches or providing a wheelchair would
    constitute “summoning medical aid”).
    28           HORTON V. CITY OF SANTA MARIA
    there was “not a scintilla of evidence in the record indicating
    that [the decedent’s] conduct was any different than one
    might expect of a person intoxicated on either drugs or
    alcohol.” 
    Id. at 350
    .
    By contrast, in Johnson v. County of Los Angeles, the
    decedent had informed sheriffs “that he was attempting to
    commit suicide and that ‘people’ were trying to torture and
    kill him,” and the decedent’s wife had indicated that the
    “Decedent was a paranoid schizophrenic, had been repeatedly
    hospitalized, . . . required immediate medication . . . to
    correct a chemical imbalance,” and “had suicidal tendencies.”
    143 Cal. App. 3d at 304. The Court of Appeal reversed the
    dismissal of the complaint alleging that the sheriffs breached
    their statutory duty to summon medical care, and held that the
    sheriffs’ “actual or constructive knowledge of Decedent’s
    need for immediate care” and “reasonable action to summon
    . . . such care” were “questions of fact to be determined at
    trial.” Id. at 317.
    This case falls between Lucas and Johnson as to the need
    for mental health care. Officer Brice, unlike the sheriffs in
    Johnson, was not specifically told by either Horton or his
    mother that Horton “required immediate medication” or was
    presently “attempting to commit suicide.” But there was
    considerably more than “a scintilla of evidence” that Horton
    required immediate medical attention: Officer Brice knew
    from his conversation with Horton’s girlfriend that Horton
    had chased his girlfriend with a knife, stabbed a friend in the
    leg and sympathized with the suspects in mass homicides,
    and, on the facts most favorable to Horton, had been told that
    Horton was suicidal, had put cigarettes out on his face, had
    recently been hospitalized after threatening to kill himself,
    and would benefit from “access to mental health.” Moreover,
    HORTON V. CITY OF SANTA MARIA                            29
    “[i]t is significant that in . . . Lucas . . . the court’s rejection
    of claims pursuant to section 845.6 was based in large part
    upon failure of proof at trial.” Zeilman, 168 Cal. App. 3d at
    1186. A “trier of fact” should be permitted to determine
    whether the information Officer Brice had “should have given
    rise to knowledge of [the] need for immediate medical care.”
    Id. at 1186–87.
    As to immediacy, the defendants argue that Officer Brice
    could not reasonably be expected to have known the urgency
    of the situation. “Liability under section 845.6 is limited to
    serious and obvious medical conditions requiring immediate
    care.” Watson v. State, 
    21 Cal. App. 4th 836
    , 841 (Ct. App.
    1993); see 
    id. at 843
    . But that immediacy standard is, under
    the applicable case law, relaxed.14 In Jett v. Penner, we held
    that the need for “immediate medical care” under § 845.6
    arises when a prisoner is instructed that he must see a doctor
    “this week” to have a fractured thumb set and placed in a
    cast. 
    439 F.3d at 1099
    . Jett thus makes clear that
    “immediate” does not signify urgent; rather, the obligation to
    summon immediate medical care requires that the public
    employee act in a “timely” manner, so as to prevent further
    injury. 
    Id. at 1093
    .
    In sum, on the facts construed in the light most favorable
    to Horton, a reasonable jury could conclude that Officer Brice
    had “reason to know” Horton had a “serious” medical
    condition and required “immediate medical care” as that term
    14
    Castro v. County of Los Angeles involved the risk of serious harm
    associated with placing a combative inmate in the same cell as another
    detainee. 833 F.3d at 1064. Castro did not address the question of how
    “immediate” the risk of serious harm — or specifically of suicide — must
    be to sustain a deliberate indifference claim under that objective standard.
    30           HORTON V. CITY OF SANTA MARIA
    is interpreted under California law, and that he failed timely
    to summon such care. The partial dissent disagrees with us
    that the evidence revealed Horton’s risk of suicide was
    immediate enough to require prompt medical attention.
    Partial Dissent 42–44. But this disagreement is precisely the
    type of question that should be left to a jury and not decided
    on summary judgement. “[Q]uestions about jail personnel’s
    actual or constructive knowledge of a prisoner’s need for
    immediate medical care as well as the reasonableness of
    actions taken to meet this need are factual questions . . .”
    Zeilman, 168 Cal. App. 3d at 1184. In reviewing the denial of
    summary judgment, “[t]his court does not weigh the evidence
    or determine the truth of the matter, but only determines
    whether there is a genuine issue for trial.” Balint v. Carson
    City, 
    180 F.3d 1047
    , 1054 (9th Cir. 1999); see also Zeilman,
    168 Cal. App. 3d at 1187 (“[D]ifficulty in proof does not
    equate to resolution as a matter of law.”). Whether Officer
    Brice had reason to know that Horton faced a need for
    immediate mental health care and failed to summon it is a
    “question[] of fact to be determined at trial” on which “we
    need not . . . speculate.” Johnson, 143 Cal. App. 3d at 316.
    Having so determined, we affirm the district court’s denial of
    summary judgment in favor of Officer Brice and the
    municipal defendants on the § 845.6 claim.
    Conclusion
    We conclude that Officer Brice is entitled to qualified
    immunity as a matter of law and so reverse the district court’s
    denial of summary judgment in favor of Officer Brice on the
    § 1983 claim. We next hold that we lack jurisdiction to
    review the district court’s denial of summary judgment in
    favor of the municipal defendants on the § 1983 claim. In
    doing so, we caution that, “it is not enough for a § 1983
    HORTON V. CITY OF SANTA MARIA                  31
    plaintiff merely to identify conduct properly attributable to
    the municipality. The plaintiff must also demonstrate that,
    through its deliberate conduct, the municipality was the
    ‘moving force’ behind the injury alleged.” Brown, 
    520 U.S. at 404
    . In holding that municipal defendants may be liable in
    a § 1983 action even absent a finding of liability on the part
    of any individual officer — and that we therefore lack
    jurisdiction to review the district court’s denial of summary
    judgment in favor of the municipal defendants on Horton’s
    § 1983 claims — we express no views on whether the
    municipal defendants here may properly be held liable.
    Instead, we remand to permit the district court to consider the
    remaining claims in light of this court’s recent guidance in
    Castro and Gordon.
    Finally, we affirm the district court’s denial of summary
    judgment on the state law claim.
    REVERSED in part, AFFIRMED in part, and
    REMANDED.
    BYBEE, Circuit Judge, dissenting in part:
    This is a tragic case. Officer Brice’s phone call with
    Horton’s mother likely left him with the impression that
    Horton was a troubled young man experiencing a difficult
    period in his life. The call could not have resulted in Officer
    Brice preventing the suicide attempt, as it is undisputed that
    Horton had already hanged himself and stopped moving by
    the time the call ended. Maj. Op. 9 n.5. But had Officer
    Brice checked on Horton immediately afterwards, his brain
    damage could have been mitigated.
    32             HORTON V. CITY OF SANTA MARIA
    None of this means, however, that Officer Brice can be
    held liable under the Fourteenth Amendment or California
    law. I join the majority opinion in concluding that Officer
    Brice is entitled to qualified immunity for Horton’s
    deliberate-indifference claim under 
    42 U.S.C. § 1983.1
     See
    Maj. Op. § II.A. The evidence fails to establish that “a
    reasonable officer would . . . have known that failing to attend
    to Horton immediately would be unlawful.” See id. at 15.
    The same reasoning dictates that we hold that Officer Brice
    is entitled to state-law immunity under California
    Government Code § 845.6. I would therefore also reverse the
    district court as to this claim, and I respectfully dissent only
    from this portion of the opinion. See Maj. Op. § II.C.
    A deliberate-indifference claim under § 1983 is not
    identical to a claim brought under § 845.6. The California
    statute is unusual, as it “confers a broad general immunity”
    on public entities and their employees, Watson v. State,
    
    26 Cal. Rptr. 2d 262
    , 265 (Cal. Ct. App. 1993), yet
    simultaneously imposes an affirmative duty on them that can
    give rise to liability under narrow circumstances, Johnson v.
    County of Los Angeles, 
    191 Cal. Rptr. 704
    , 717 (Cal. Ct. App.
    1983); Nelson v. State, 
    188 Cal. Rptr. 479
    , 483 (Cal. Ct. App.
    1982). Specifically, the statute’s first clause confers
    immunity from suit “for injury proximately caused by the
    failure of the employee to furnish or obtain medical care for
    a prisoner in his custody . . . .” Cal. Gov’t Code § 845.6
    (emphasis added); see also Castaneda v. Dep’t of Corr. &
    Rehab., 
    151 Cal. Rptr. 3d 648
    , 663 (Cal. Ct. App. 2013). The
    second clause is the exception to this rule, exposing a public
    1
    I also join the opinion’s subsequent section concluding that we lack
    jurisdiction to review the denial of summary judgment as to Horton’s
    Monell claim. See Maj. Op. § II.B.
    HORTON V. CITY OF SANTA MARIA                  33
    employee to suit only when he “knows or has reason to know
    that the prisoner is in need of immediate medical care and he
    fails to take reasonable action to summon such medical care.”
    Cal. Gov’t Code § 845.6 (emphasis added). “Thus, section
    845.6 creates out of the general immunity a limited cause of
    action against a public entity for its employees’ failure to
    summon immediate medical care only. The statute does not
    create liability of the public entity for malpractice in
    furnishing or obtaining that medical care.” Castaneda,
    151 Cal. Rptr. 3d at 663 (first emphasis added) (citations
    omitted).
    To state a claim under § 845.6, a plaintiff must satisfy
    three elements. See id. First, he must establish that whatever
    action he contends that the defendant should have taken—the
    statute is after all explicitly premised only on a failure to
    act—constitutes summoning medical care. See Cal. Gov’t
    Code § 845.6. Next, there is the knowledge component: the
    plaintiff must prove that the defendant knew or should have
    known that the plaintiff was in need of this medical care and
    that the need was immediate. Id. Finally, the plaintiff must
    establish that the defendant failed to act reasonably to meet
    the medical need. Id.
    Horton cannot satisfy either of the first two elements. He
    has thus failed, as a matter of law, to establish that Officer
    Brice may be subjected to suit under state law. I address each
    element in turn.
    I
    Section 845.6 creates liability only for the failure to
    summon medical care rather than for all omissions by a
    public employee that cause injury to a person in his custody.
    34           HORTON V. CITY OF SANTA MARIA
    Consider, for instance, a Sheriff’s deputy who is tasked with
    assembling a new bunk bed in a cell at a county jail and does
    so negligently by failing to read the instructions and not using
    all provided parts. If the bed later collapses and consequently
    breaks its occupant’s leg, § 845.6 would not expose the
    deputy to liability for that injury. The deputy might be liable
    under some other law, but not for violating § 845.6.
    Conversely, if a different deputy on duty witnessed the
    accident and took no action despite the prisoner’s complaints
    of pain to his leg, this second deputy would likely be liable;
    he would not be immune from suit for any additional injury
    caused by the delay in summoning medical care to treat the
    leg. See, e.g., Jett v. Penner, 
    439 F.3d 1091
    , 1099 (9th Cir.
    2006).
    A claim premised on suicidal ideation creates a
    particularly difficult question as to what types of omissions
    would constitute a failure to summon medical care. Even if
    an officer had knowledge that there was an imminent risk that
    the prisoner would make an attempt on his own life, it would
    be difficult to say that a failure to remove that prisoner’s
    bedsheets and shoelaces would fall within this statute’s ambit
    because it is not natural to describe the removal of such items
    as summoning medical care. The failure to remove them
    might violate some other provision of California law, but the
    omission is not an obvious violation of § 845.6.
    Here, our analysis is complicated by the fact that Horton’s
    complaint consists of a single conclusory allegation regarding
    what omissions purportedly violated § 845.6: “Defendants
    . . . knew, or had reason to know, that Shane Horton was in
    need of immediate medical care, supervision and
    safeguarding and that he was suicidal and at risk of injuring
    himself, but failed to take reasonable action to summon such
    HORTON V. CITY OF SANTA MARIA                          35
    medical care . . . .” Horton adds little clarity on appeal,
    merely highlighting the fact that he was “already slumped on
    the floor motionless when Officer Brice finished” the call as
    evidence that he “was in immediate need of medical
    attention.” But the fact that Horton needed to be resuscitated
    once he had already hanged himself says nothing about what
    actions Officer Brice should have taken before he returned to
    Horton’s cell and discovered the suicide attempt.2 In other
    words, Horton’s argument is circular; he implies that, because
    he was in need of medical care once he had hanged himself,
    any omission by Officer Brice constituted a failure to
    summon medical care.
    Ultimately, it is evident that Horton’s state-law claim, like
    his § 1983 claim, is premised on his contention that “the
    information communicated by . . . Horton’s mother should
    have prompted [Officer Brice] to check on Horton promptly
    and discover the need for immediate medical care.” As
    addressed below, I do not believe Horton has provided any
    evidence that Officer Brice knew or should have known that
    Horton was in immediate danger of harming himself. But
    even assuming that this knowledge component is satisfied,
    the majority opinion does not address how Officer Brice’s
    failure to check on Horton immediately after the phone call
    constitutes a failure to summon medical care. The majority
    has not explained why this statute even applies in this case.3
    2
    Horton has never alleged—nor does the record show—that Officer
    Brice delayed in summoning emergency care after he discovered that
    Horton had hanged himself. Rather, Officer Brice personally administered
    CPR until paramedics arrived.
    3
    Section 845.6 grants immunity to an officer who fails to “furnish or
    obtain medical care” but limits an officer’s liability to a failure “to
    summon such medical care” when the officer has actual or constructive
    36             HORTON V. CITY OF SANTA MARIA
    The California Court of Appeal emphasized this precise
    deficiency in Lucas v. City of Long Beach, where the
    decedent hanged himself in his cell after being arrested on a
    charge of being drunk and disorderly:
    Plaintiff, [the decedent’s mother] . . . , offered
    no evidence as to what kind of medical care
    she claims should have been provided and
    more importantly she offered no evidence as
    to how such medical care could have
    prevented the death. [The decedent] was not
    in fact in need of immediate medical care and
    clearly lack of medical care did not “cause”
    the death.
    True the continuous presence in the cell of a
    doctor, a nurse, or, for that matter, a
    policeman probably would have prevented the
    suicide. The jury apparently reasoned along
    these lines. Government Code section 845.6,
    knowledge of its immediate need. Cal. Gov’t Code § 845.6 (emphasis
    added). Therefore, this statute does not create an affirmative duty for an
    officer to personally furnish medical care. Castaneda, 151 Cal. Rptr. 3d
    at 666 (“Were we to conclude the duty under section 845.6 includes
    furnishing, monitoring, followup, or subsequent care for the same
    condition, . . . we would be expanding the liability of the public entity
    beyond that contemplated by the Legislature.”). Accordingly, if an inmate
    accidently severs his hand in the prison’s machine shop, a supervising
    guard will undoubtedly be liable under § 845.6 for not radioing in for
    immediate medical aid. The guard would, however, be immune from suit
    if the inmate alleged only that the guard should have personally
    administered a makeshift tourniquet. This distinction demonstrates why
    California courts have concluded that the statute “is very narrowly
    written,” id. at 663, and further highlights that Horton’s claim is not
    premised on a failure to summon care.
    HORTON V. CITY OF SANTA MARIA                         37
    however, in affixing liability for failure to
    summon “immediate medical care” for a
    person in need thereof envisions liability for
    injury resulting from the failure to treat the
    physical condition requiring treatment and not
    for some other incidental injury that might
    have been prevented by the mere presence of
    medical personnel. The jury’s findings that it
    was negligence not to provide medical
    treatment and that that failure was the “cause”
    of death are not supported by any evidence to
    be found in the record.
    
    131 Cal. Rptr. 470
    , 475 (Cal. Ct. App. 1976) (emphasis
    added). Lucas thus demonstrates that, as discussed above, not
    all forms of omission give rise to liability under § 845.6.
    Although Officer Brice’s presence in Horton’s cell
    immediately after the call may have prevented Horton from
    suffering the degree of brain damage that he did, any failure
    to check on Horton sooner falls outside the statute’s narrow
    exception to immunity.
    Rather than confronting this dispositive flaw in Horton’s
    state-law claim,4 the majority summarily asserts that the
    claim is “not . . . limited” to “Officer Brice’s own failure to
    return immediately to Horton’s cell . . . .” Maj. Op. 27.
    Tellingly, the majority supports this conclusion by citing only
    to Horton’s complaint, which, as seen above, does not allege
    4
    The majority fails to address the above-quoted reasoning in Lucas
    regarding the medical-care element under § 845.6. Instead, the majority
    addresses Lucas only in the context of the statute’s knowledge
    element—i.e., whether Officer Brice should have known that Horton
    posed an immediate suicide risk. Maj. Op. 27–29.
    38             HORTON V. CITY OF SANTA MARIA
    a single specific action that Officer Brice failed to take. See
    id. This is unsurprising. Nothing in Horton’s briefing or the
    record indicates that his claim, as to Officer Brice, is
    premised on anything other than the officer not immediately
    checking on him.
    Undeterred, the majority supplements Horton’s claim for
    him, concluding that Officer Brice could have ordered a
    psychiatric evaluation for Horton—as Officer Schneider
    suggested earlier that day.5 Id. I have two objections. First,
    Horton has never contended that such an evaluation is the
    type of medical care that Officer Brice should have
    summoned after the call with his mother. It is improper for
    the majority to deny Officer Brice state-law immunity based
    on an argument that it manufactured. See Greenwood v. FAA,
    
    28 F.3d 971
    , 977 (9th Cir. 1994).
    But second, even if properly before us, this new argument
    does not cure this claim. The majority’s assertion that Officer
    Brice should have ordered a psychiatric evaluation is a
    circuitous attempt to argue that the officer or third-party
    medical personnel failed to furnish medical care and, in the
    process, could have more quickly discovered the suicide
    attempt. California cases have repeatedly rejected such
    claims. See, e.g., Lucas, 
    131 Cal. Rptr. at 475
     (“[S]ection
    845.6 . . . , in affixing liability for failure to summon
    ‘immediate medical care’ for a person in need thereof
    envisions liability for injury resulting from the failure to treat
    5
    Officer Schneider referenced “[p]robably do[ing] a psych or
    something” to Horton after the two had a half-an-hour conversation.
    Officer Brice was not at the police station at the time, and the record does
    not show that Schneider later conveyed this suggestion or the
    conversation’s content to Brice.
    HORTON V. CITY OF SANTA MARIA                     39
    the physical condition requiring treatment and not for some
    other incidental injury that might have been prevented by the
    mere presence of medical personnel.”); see also Castaneda,
    151 Cal. Rptr. 3d at 663–64 (discussing “[t]he distinction
    between failure to summon medical care—for which the State
    can be held liable under section 845.6—on the one hand, and
    negligence in providing care—for which the State is
    immune—on the other hand”); id. at 664 n.10, 666 (repeating
    the point); Nelson, 
    188 Cal. Rptr. at 485
     (“Failure of a
    practitioner to prescribe or provide necessary medication or
    treatment . . . is . . . medical malpractice . . . [but] cannot be
    characterized as a failure to summon medical care.”).
    Moreover, the medical care that the majority insists upon
    would not have addressed Horton’s medical needs—he had
    already hanged himself by the time that the call ended. There
    is also no evidence that ordering a psychiatric evaluation
    would have resulted in Officer Brice more quickly checking
    on Horton.        Officer Brice could have ordered an
    evaluation—a paperwork or telephone request—without
    checking on Horton. It is likely that doing so would have
    required the officer to spend additional time on administrative
    tasks outside of Horton’s presence, only further delaying his
    return to the cell. Accordingly, Horton has failed to show
    that any purported omission by Officer Brice falls within the
    scope of § 845.6 liability.
    By disregarding the statute’s medical-care element, the
    majority opinion undermines California’s intent to immunize
    its employees and to allow suit only when an employee has
    actual or constructive knowledge of an immediate medical
    need. The opinion has converted § 845.6 into a general
    negligence provision, ignoring “[t]he limited nature of the
    40           HORTON V. CITY OF SANTA MARIA
    duty to summon under section 845.6.” Castaneda, 151 Cal.
    Rptr. 3d at 666.
    II
    Even if Horton could establish that any omission
    constituted a failure to summon medical care, he has
    separately failed to provide evidence that Officer Brice knew
    or should have known that there was an immediate danger
    that he would harm himself. In concluding that Horton has
    raised a triable issue, the opinion cites to Zeilman v. County
    of Kern for the proposition that “jail personnel’s actual or
    constructive knowledge of a prisoner’s need for immediate
    medical care as well as the reasonableness of actions taken to
    meet this need are factual questions . . . .” 
    214 Cal. Rptr. 746
    ,
    753 (Cal. Ct. App. 1985); Maj. Op. 30. But even Zeilman
    recognized that summary judgment on § 845.6 claims can be
    appropriate in some circumstances, 
    214 Cal. Rptr. at 754
    , and
    its facts are distinguishable from this case.
    In Zeilman, the plaintiff was being booked at the county
    jail following her arrest and was relying on crutches due to a
    ski accident. 
    Id.
     at 747–48. After the booking process was
    complete, a deputy directed the plaintiff to sit down at a
    nearby chair, but she fell when her crutches slipped out from
    under her. 
    Id.
     at 748–49, 754. In opposing summary
    judgment on her § 845.6 claim, she presented a declaration
    from her attorney “stating that he arrived at the jail during the
    booking procedure and could observe his client being booked,
    in an ‘aggitated [sic], emotional and weakened condition
    which was easily apparent to him and any other person in his
    vicinity.’” Id. at 748 (emphasis added). The Court of Appeal
    reversed the trial court’s grant of summary judgment,
    reasoning that a jury had to determine whether this evidence
    HORTON V. CITY OF SANTA MARIA                           41
    and the plaintiff’s use of crutches “should have given rise to
    knowledge of her need for immediate medical care.” Id. at
    754.
    In reaching this conclusion, Zeilman distinguished these
    facts from Lucas, the detainee-suicide case discussed above.
    Id. at 753–55. In Lucas, the plaintiff not only failed to
    establish that the officer’s purported omission constituted
    medical care, but she also failed to provide evidence that the
    officer should have known that there was an immediate
    suicide risk. Lucas, 
    131 Cal. Rptr. at 475
    . Indeed the
    decedent was merely drunk and visibly upset about “the
    effect that his arrest would have on his mother . . . .” 
    Id.
    (“[T]here is not a scintilla of evidence in the record indicating
    that his conduct was any different than one might expect of
    a person intoxicated on either drugs or alcohol.”).
    The Zeilman court also addressed Kinney v. County of
    Contra Costa, where the detainee merely asked the officer if
    she could be given something for “a very bad headache” and
    was denied. 
    87 Cal. Rptr. 638
    , 644 (Cal. Ct. App. 1970).
    Although the plaintiff claimed she was “ready to collapse” by
    the time she was released from the police station, the Court of
    Appeal held that a request for aspirin “cannot reasonably be
    deemed notice ‘that the prisoner is in need of immediate
    medical care.’” 
    Id.
    In distinguishing Lucas and Kinney, Zeilman emphasized
    that both earlier cases had proceeded to a jury but that the
    plaintiffs had failed to produce sufficient evidence at trial.6
    6
    In Lucas, a jury rendered a verdict in the plaintiff’s favor, but the
    Court of Appeal reversed on a sufficiency-of-the-evidence claim. 
    131 Cal. Rptr. at 474
    . The trial court in Kinney issued a judgment of nonsuit at the
    42              HORTON V. CITY OF SANTA MARIA
    
    214 Cal. Rptr. at 754
    . The majority in our case highlights this
    point without acknowledging that the Zeilman court
    nonetheless concluded that summary judgment might have
    been proper in both Lucas and Kinney. 
    Id.
     Accordingly,
    Zeilman does not stand for the proposition that a § 845.6
    claim per se precludes summary judgment. Such relief would
    have certainly been warranted in Lucas, where the plaintiff
    failed to provide evidence supporting the medical-care and
    knowledge elements. In contrast, the plaintiff in Zeilman
    came forward with at least some evidence that the deputy
    should have known she was in need of immediate assistance7
    in the form of her lawyer’s attestation that her weakened
    condition was visibly and readily apparent.
    This brings me to the evidence in this case. Horton’s
    mother testified during her deposition that she told Officer
    Brice “‘everything’ about the December 13, 2012
    incident—Horton’s use of drugs, the cigarette marks on his
    face and hands, the knife he held to his throat, his
    hospitalization with an initial ‘5150’ hold for risk of suicide,
    the CARES official’s conclusion that he could be discharged
    because his conduct was due to drugs not suicidal ideation,
    and [Mrs. Horton’s] disagreement with that conclusion.”
    Maj. Op. 8. She “testified that she also told Officer Brice that
    her son was depressed and suicidal, that she was really
    close of the plaintiff’s case in chief, which the Court of Appeal affirmed.
    
    87 Cal. Rptr. at 644
    .
    7
    I question whether failing to help the plaintiff in Zeilman to her chair
    constitutes a failure to summon medical care. Although the Zeilman court
    quoted the relevant medical-care language from Lucas, it did not address
    that element in distinguishing the two cases, which appears not to have
    been in dispute.
    HORTON V. CITY OF SANTA MARIA                   43
    worried about him, and that she believed he could be helped
    in the judicial system.” 
    Id.
    This testimony admittedly distinguishes our case from
    Lucas, where there was no evidence whatsoever that the
    detainee suffered from suicidal ideation. But even when the
    evidence here is taken in the light most favorable to Horton,
    I would hold that no reasonable jury could find that Officer
    Brice should have known that there was an immediate risk
    that Horton would harm himself and that the officer therefore
    needed to take immediate action. A person can suffer from
    depression and suicidal thoughts for years without ever
    harming himself. Indeed, the incident that Horton’s mother
    described to Officer Brice occurred two weeks prior to the
    arrest, and she provided no evidence that Horton had made
    any attempts or threats on his life in the intervening period.
    Seeking “help[] in the judicial system” is not close to a call
    for immediate assistance for someone who recently exhibited
    suicidal ideation.
    This is not a case where Horton’s parents had imposed an
    informal 24/7 suicide watch on him. His father had kicked
    him out of the house after the glass-breaking incident, so it
    appears Horton was living independently, without supervision
    for the two weeks preceding his arrest. Moreover, his mother
    did not rush down to the police station once she heard that her
    son had been arrested; rather, she had just told Horton that
    she would not bail him out. Horton’s mother was certainly
    concerned about his well-being, but she never claims to have
    expressed to Officer Brice that Horton would likely make an
    attempt on his life if the officer did not take immediate action
    to ensure Horton was unable to do so—e.g., by removing his
    belt, moving him to a secured, padded cell, and monitoring
    him constantly. It would certainly have been prudent of
    44            HORTON V. CITY OF SANTA MARIA
    Officer Brice to pass along the information Horton’s mother
    claims to have given him to the officials at the county jail
    once Horton was transferred, but that falls far short of failing
    to recognize Horton’s immediate need for medical care.
    Moreover, Horton’s mother testified that she spoke to
    Officer Brice for ten to fifteen minutes—a substantial amount
    of time. Had she thought her son was in immediate danger of
    harming himself, she would have told Officer Brice to drop
    the phone and rush to Horton’s cell. Indeed, if anything, the
    officer’s patient call with Horton’s mother would have
    reinforced that Horton needed a psychiatric
    evaluation—which was likely obtainable at the county jail
    rather than at the police station where Horton was being
    temporarily held.
    The majority does not address this absence of evidence.
    Nor does it attempt to reconcile its conclusion that Officer
    Brice, for the purpose of the state-law claim, should have
    known that Horton posed an immediate suicide risk with our
    holding regarding his § 1983 claim: “Based on these facts,
    . . . a reasonable officer would not have known that failing to
    attend to Horton immediately would be unlawful.” Maj. Op.
    15.
    The majority instead summarily cites Jett for the
    proposition that the “immediacy standard” under § 845.6 is
    more “relaxed” than under § 1983 deliberate-indifference
    claims.8 Maj. Op. 29. But this conclusion misconstrues Jett.
    8
    Horton does not cite Jett. Nor does he contend that a claim
    premised on suicidal ideation entails a lesser showing of immediacy of
    harm under § 845.6 than under the deliberate-indifference standard.
    HORTON V. CITY OF SANTA MARIA                         45
    There, the emergency-room doctor instructed the prisoner-
    plaintiff to follow-up with an orthopedic doctor “early this
    week” after he fractured his thumb. Jett, 
    439 F.3d at 1094
    .
    The plaintiff saw a prison doctor three days later, but his hand
    was too swollen to be placed in a permanent cast. 
    Id.
    Despite reports of pain and numerous requests to visit an
    orthopedist, it took an additional two months for the plaintiff
    to be seen even by another prison doctor. 
    Id.
     After four
    additional months, the plaintiff finally visited an orthopedic
    specialist, “who determined [the plaintiff] should be referred
    to a hand specialist because the fracture had healed
    improperly.” 
    Id. at 1095
    . The evidence demonstrated that
    the delay in seeing an orthopedist prevented the fracture from
    correctly aligning. 
    Id. at 1098
    .
    We reversed the district court’s grant of summary
    judgment on the plaintiff’s deliberate-indifference claims,
    concluding that there was evidence that several prison
    officials knew of but ignored the plaintiff’s need to set his
    fracture. 
    Id.
     In regard to his § 845.6 claim, we held that there
    was “a triable issue of fact . . . as to whether [the plaintiff]
    received immediate medical care for his diagnosed fractured
    thumb because the fracture was not set and placed in a cast.”
    Id. at 1099. We reasoned that “the need for ‘immediate
    medical care’ can arise more than once in relation to an
    ongoing serious medical condition” and that this need “arose
    as soon as [the plaintiff’s] swelling subsided and his fracture
    could be reduced and a cast applied.” Id. (emphasis added).
    Accordingly, Jett provides no insight into how immediate
    a medical need must be under § 845.6. The plaintiff’s
    Again, it is improper for the majority to raise arguments that Horton has
    failed to advance.
    46             HORTON V. CITY OF SANTA MARIA
    medical condition was ongoing and his need for care
    resurfaced as soon as his reduced swelling made the original
    prescribed treatment possible.9 Thus, the key point in Jett
    regarding both § 845.6 and deliberate indifference is that
    there was evidence that prison officials had actual knowledge
    that the plaintiff had a time-sensitive medical need and took
    no action for many months. The case does not support the
    majority’s conclusion.
    In my view, Horton’s claim fails because he has not
    provided evidence that Officer Brice should have known that
    Horton posed such a degree of suicide risk that the officer
    should have immediately rushed to his cell instead of
    spending twelve to seventeen minutes arranging to transfer
    Horton and another detainee to county jail.
    III
    I sympathize deeply with Horton and his mother, but there
    is no basis under California law for subjecting Officer Brice

    The California Court of Appeal has criticized our conclusion in Jett,
    reasoning that the duty to summon medical care does not extend to
    ensuring that proper follow-up treatment—i.e., setting the fracture—is
    eventually provided. Castaneda, 151 Cal. Rptr. 3d at 666 (“[T]he Ninth
    Circuit’s application of section 845.6 ignores California authority
    interpreting that statute. California courts hold the failure to prescribe
    necessary medication or, once summoned to provide treatment, to ensure
    proper diagnosis, or to monitor the progress of an inmate that the public
    employee has been summoned to assist, are issues relating to the manner
    in which medical care is provided, and do not subject the State to liability
    under section 845.6 for failure to summon.”). The majority opinion
    creates additional tension between Jett and Castaneda because Jett is
    inapposite and should not have been cited. See Scalia v. County of Kern,
    
    308 F. Supp. 3d 1064
    , 1087 (E.D. Cal. 2018) (declining to follow Jett’s
    interpretation of § 845.6 in light of Castenada).
    HORTON V. CITY OF SANTA MARIA                  47
    to suit. Considered in the light most favorable to Horton, the
    events earlier that day and the phone call with his mother did
    not imbue Officer Brice with the actual or constructive
    knowledge that Horton would attempt suicide at any moment.
    And although it may have been prudent for Officer Brice to
    immediately check on Horton, his decision not to do so is not
    a failure to summon medical care. For these two independent
    reasons, I would reverse the district court’s denial of
    summary judgment to Officer Brice on Horton’s § 845.6
    claim.
    I respectfully dissent as to this claim.
