    SUMMARY **
    Prisoner Civil Rights
    The panel reversed the district court’s jury verdict in
    favor of defendant prison officials and remanded for further
    proceedings in an action brought by a California state
    prisoner pursuant to 
    42 U.S.C. § 1983
     alleging that
    defendants used excessive force against him and delayed his
    access to medical assistance.
    Plaintiff consented to the jurisdiction of a magistrate
    judge pursuant to 
    28 U.S.C. § 636
    (c). Nearly two years later,
    defendants declined consent, and the case was assigned to a
    district court judge. Thereafter, the magistrate judge
    originally assigned to this case retired, and another
    magistrate judge took over the case to address pretrial
    motions. Following an adverse ruling on a motion to
    compel, plaintiff filed a motion to withdraw his consent to
    magistrate judge jurisdiction. The magistrate judge denied
    plaintiff’s motion, stating that, pursuant to 
    28 U.S.C. § 636
    (c)(4), a request to withdraw consent will be granted
    only upon a showing of good cause or extraordinary
    circumstances, and that disagreement with a ruling did not
    amount to good cause. Defendants subsequently consented
    to magistrate judge jurisdiction, almost four years after
    plaintiff’s consent.
    The panel held that a party need not satisfy the good
    cause or extraordinary circumstances standard provided in
    **
    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    GILMORE V. LOCKARD                        3
    § 636(c)(4) in order to withdraw magistrate judge consent
    before all parties have consented. The panel held that
    because the magistrate judge erroneously required such a
    showing by plaintiff, and because under the circumstances
    his motion to withdraw consent should have been granted,
    the magistrate judge lacked jurisdiction to conduct the trial.
    While plaintiff’s case was pending, the Attorney General
    notified him that one of the defendants had died, but did not
    identify a personal representative for the defendant’s estate.
    The district court, adopting the magistrate judge’s
    recommendation, dismissed the deceased defendant from the
    action, along with plaintiff’s Eighth Amendment deliberate
    indifference claim. The district court held that additional
    attempts to identify a representative would be futile due to
    Federal Rule of Civil Procedure 25(a)’s 90-day filing
    requirement.
    The panel held that the magistrate judge erred by placing
    the burden on plaintiff to identify the deceased defendant’s
    successor or personal representative. The panel concluded
    that Rule 25(a)’s 90-day window was not triggered, and
    therefore the panel reversed the dismissal of the deceased
    defendant, and reversed the dismissal of plaintiff’s deliberate
    indifference to medical needs claim.
    The panel stated that because it was reversing the jury
    verdict and remanding for further proceedings based on the
    magistrate judge’s lack of jurisdiction, it was not necessary
    to consider plaintiff’s evidentiary challenges in detail.
    However, for the guidance of the trial court on remand, the
    panel noted that the probative value of defendants’ expert
    testimony about gangs to which plaintiff had no connection
    was minimal and was substantially outweighed by the
    danger of unfair prejudice.

    OPINION
    M. SMITH, Circuit Judge:
    Plaintiff Cary Dwayne Gilmore filed an action pursuant
    to 
    42 U.S.C. § 1983
    , alleging civil rights violations by
    various prison officials (together, Defendants) following an
    incident at Kern Valley State Prison (Kern Valley). A jury
    ultimately ruled against Gilmore, finding that Defendants
    did not use excessive force during the alleged incident.
    We reverse on several grounds.
    FACTUAL AND PROCEDURAL BACKGROUND
    I. Factual Background
    Gilmore alleged that on July 8, 2010, after an alarm
    sounded due to a disturbance created by two non-party
    inmates at Kern Valley, he was beginning to lie down—
    “prone out”—when Defendant Chad Lockard shot him with
    a sponge round in the right leg near his knee. Lockard then
    directed Defendant Cesar Lopez to check on Gilmore, who
    was on the ground after being shot. Gilmore claimed that
    GILMORE V. LOCKARD                       5
    Lopez then began to pepper spray him. Defendant John
    Hightower also allegedly walked over and pepper sprayed
    Gilmore, until both he and Lopez had emptied their pepper
    spray cans. Afterwards, Defendant J.J. Torres handcuffed
    Gilmore and forced him to walk despite his knee injury.
    Gilmore alleged that Torres repeatedly forced him into
    obstacles such as door frames and walls, breaking his glasses
    and injuring his face. Torres purportedly laughed and said,
    “You gotta watch where you’re going Gilmore!” Gilmore
    claimed that Torres then made him sit on hot asphalt for
    27 minutes while he awaited medical attention, exacerbating
    the “burning” from the pepper spray. Finally, when Torres
    agreed to decontaminate Gilmore, he forced Gilmore to
    kneel while he sprayed him with water. Afterwards,
    Gilmore received medical attention for the gunshot wound.
    II. Procedural Background
    Gilmore filed this action pursuant to 
    42 U.S.C. § 1983
    ,
    alleging that Defendants used excessive force when
    responding to the incident at Kern Valley, and subsequently
    delayed his access to medical assistance. On March 2, 2017,
    after trial, a jury found in favor of Defendants.
    A. Motion to Withdraw Consent to Magistrate
    Judge Jurisdiction
    On June 29, 2012, Gilmore consented to the jurisdiction
    of a magistrate judge pursuant to 
    28 U.S.C. § 636
    (c). Nearly
    two years later, on May 19, 2014, Defendants declined
    consent, and the case was then assigned to District Judge
    Lawrence J. O’Neill. The district court rejected Gilmore’s
    objection to the reassignment, noting that “under § 636(c), if
    all parties do not consent to Magistrate Judge jurisdiction, a
    District Judge must be assigned as presiding judge.”
    Thereafter, the magistrate judge originally assigned to this
    6                 GILMORE V. LOCKARD
    case retired, and Magistrate Judge Stanley A. Boone took
    over the case, at this point in the case to address pretrial
    motions.
    On October 19, 2015, following an adverse ruling on a
    motion to compel, Gilmore filed a motion to withdraw his
    consent to magistrate judge jurisdiction. The magistrate
    judge stated that, pursuant to 
    28 U.S.C. § 636
    (c)(4), “a
    request to withdraw consent will be granted only upon a
    showing of good cause or extraordinary circumstances.”
    Finding that Gilmore’s disagreement with his ruling—
    Gilmore had suggested that the magistrate judge “ha[d]
    shown partiality for defendants” when ruling on the
    motion—did not amount to good cause, the magistrate judge
    denied Gilmore’s motion.
    On September 1, 2016, over four years after Gilmore
    consented to magistrate judge jurisdiction, Defendants
    finally gave their consent to Magistrate Judge Boone
    conducting all further proceedings. Pursuant to 
    28 U.S.C. § 636
    (c), the case was thereafter assigned to Magistrate
    Judge Boone for all pretrial and trial proceedings.
    B. Motion to Substitute Defendant Torres
    On February 24, 2014, the Deputy Attorney General
    (AG) representing Lopez and Hightower notified Gilmore
    that Torres had died, but did not identify a personal
    representative for Torres’s estate. The notice stated,
    “Counsel for Defendant Torres is informed that the
    Defendant has died.” Defendants now claim that the AG
    sent the notice in error because the AG represented only
    Lopez and Hightower at the time. On March 5, 2014,
    Gilmore filed an “Opposition and Reply to Notice of
    Defendant’s Death,” which the magistrate judge construed
    as a motion to substitute parties. The magistrate judge
    GILMORE V. LOCKARD                        7
    denied this motion without prejudice, noting that “Plaintiff
    . . . is responsible for identifying and finding J.J. Torres’
    heirs or representatives.”
    Gilmore then filed a second substitution motion,
    asserting that counsel for Torres—the AG, as stated in the
    notice—was the representative of the estate, and requesting
    that the Deputy AG assigned to the case be served with his
    motion. The magistrate judge denied the motion, again
    asserting that Gilmore was responsible for providing the
    name and address of Torres’s heir or representative.
    Gilmore then filed three additional substitution motions in
    an attempt to provide information about Mrs. Elizabeth
    Torres, Torres’s widow, whom Gilmore claimed was
    Torres’s heir. After the magistrate judge allowed limited
    discovery concerning the proper party to substitute, Gilmore
    offered as proof two obituaries indicating that Torres was
    survived by his wife, as well as copies of the white pages
    indicating Mrs. Torres’s address. The magistrate judge
    again denied Gilmore’s substitution motions because he
    found the evidence insufficient.
    On November 20, 2014, Gilmore filed his final motion
    to substitute parties, which included a declaration in addition
    to the evidence previously submitted. Gilmore’s declaration
    described a conversation between Gilmore’s then-fiancée,
    Thalesha Denise Clay, and Mrs. Torres, wherein the latter
    confirmed that she was the administrator of Torres’s estate.
    In further briefing, Gilmore disclosed that Clay had posed as
    a Department of Veterans Affairs employee in order to
    solicit answers from Mrs. Torres. The magistrate judge
    recommended denying Gilmore’s motion with prejudice,
    noting that the declaration was inadmissible hearsay; that the
    remaining evidence was insufficient to identify Mrs. Torres
    as Torres’s legal representative; and that further attempts to
    8                  GILMORE V. LOCKARD
    identify a representative would be futile due to Federal Rule
    of Civil Procedure 25(a)’s 90-day filing requirement.
    The district court adopted the magistrate judge’s
    recommendation and dismissed Torres from the action,
    along with Gilmore’s Eighth Amendment deliberate
    indifference claim.
    ANALYSIS
    Gilmore argues that the magistrate judge committed
    several reversible errors over the course of the multi-year
    litigation. We address each in turn.
    I. Magistrate Judge Jurisdiction
    Gilmore first argues that the magistrate judge lacked
    jurisdiction to conduct the trial pursuant to 
    28 U.S.C. § 636
    (c). Specifically, he contends that the magistrate judge
    erred by erroneously requiring that Gilmore show “good
    cause” in order to withdraw his consent.
    We review de novo whether a magistrate judge had
    jurisdiction over a case. Irwin v. Mascott, 
    370 F.3d 924
    , 929
    (9th Cir. 2004). “[T]he federal litigant has a personal right,
    subject to exceptions in certain classes of cases, to demand
    Article III adjudication of a civil suit.” Pacemaker
    Diagnostic Clinic of Am., Inc. v. Instromedix, Inc., 
    725 F.2d 537
    , 541 (9th Cir. 1984). Like other fundamental rights, this
    right can be waived: “When authorized under 
    28 U.S.C. § 636
    (c), a magistrate judge may, if all parties consent,
    conduct a civil action or proceeding, including a jury . . .
    trial.” Fed. R. Civ. P. 73(a).
    Here, Gilmore originally consented to magistrate judge
    jurisdiction on June 29, 2012. Defendants then declined
    GILMORE V. LOCKARD                        9
    magistrate judge jurisdiction on May 19, 2014. Although
    Defendants later consented to magistrate judge jurisdiction,
    prior to that decision Gilmore sought to withdraw his
    consent, “believ[ing] that Magistrate Judge Stanley A.
    Boone ha[d] shown partiality for defendants and will not be
    an impartial magistrate.” The magistrate judge denied
    Gilmore’s motion, citing § 636(c)(4) and its standard for
    withdrawing consent. That statute states, “The court may,
    for good cause shown on its own motion, or under
    extraordinary circumstances shown by any party, vacate a
    reference of a civil matter to a magistrate judge under this
    subsection.” 
    28 U.S.C. § 636
    (c)(4).
    Gilmore argues that because he sought to withdraw
    consent before all parties consented to magistrate judge
    jurisdiction, the civil matter was not yet properly before the
    magistrate judge, and so the “good cause” standard under
    § 636(c) does not apply. Whether § 636(c)’s good cause
    standard applies prior to consent by all parties is a matter of
    first impression in our court.
    The text of the statute suggests that Gilmore is correct,
    and that a showing of good cause is not required before all
    parties have consented. Section 636(c) generally pertains to
    matters where all parties have consented to magistrate judge
    jurisdiction. Subsection (c)(1) applies only “[u]pon the
    consent of the parties,” and subsections (c)(2) and (c)(3) only
    relate to cases under subsection (c)(1). Id. § 636(c)(1)–(3).
    It follows then that subsection (c)(4) similarly applies only
    when the magistrate judge has jurisdiction over all
    proceedings, “[u]pon the consent of the parties.” By
    contrast, at the time the magistrate judge ruled on Gilmore’s
    motion to withdraw, he only had authority pursuant to
    § 636(b), which applies where “a judge [] designate[s] a
    magistrate judge to hear and determine any pretrial matter
    10                 GILMORE V. LOCKARD
    pending before the court.” Id. § 636(b)(1)(A). Section
    636(b) does not have a good cause or extraordinary
    circumstances requirement, and so Gilmore was not required
    to make such a showing when he moved to withdraw his
    consent.
    Defendants claim that the magistrate judge retained
    jurisdiction pursuant to § 636(c) at the time of Gilmore’s
    motion to withdraw, but this is inaccurate. A district court
    in our circuit explained succinctly the key distinction that
    applies in this case:
    There is a distinction between assignment of
    an action to a Magistrate Judge pursuant to
    
    28 U.S.C. § 636
    (b) and reassignment of an
    action to a Magistrate Judge pursuant to 
    28 U.S.C. § 636
    (c) . . . . When an action is filed,
    it is assigned to a United States District Judge
    and a United States Magistrate Judge. If all
    the parties consent to Magistrate Judge
    jurisdiction pursuant to § 636(c), the action is
    reassigned by the United States District
    Judge assigned to the case to the Magistrate
    Judge assigned to the case, and the
    Magistrate Judge conducts all further
    proceeding[s], including trial. When plaintiff
    filled out the consent/decline form and
    checked the box marked “Consent,” he was
    consenting pursuant to section 636(c).
    However, [at that point] plaintiff’s consent
    did not result in reassignment of this action to
    a Magistrate Judge. Cases are reassigned to
    a Magistrate Judge only if all parties consent.
    If one or more parties decline Magistrate
    Judge jurisdiction, the District Judge will
    GILMORE V. LOCKARD                            11
    resolve all dispositive matters and conduct
    the trial, if there is one.
    Page v. California, No. 1:06-cv-01409 LJO DLB PC, 
    2008 WL 3976933
    , at *1 (E.D. Cal. Aug. 20, 2008). Gilmore filed
    his motion to withdraw consent on October 19, 2015—after
    Defendants denied consent, after the case was assigned to
    District Judge Lawrence J. O’Neill, and before Defendants
    later consented to magistrate judge jurisdiction. Therefore,
    the magistrate judge did not have jurisdiction pursuant to
    § 636(c). 1
    We must necessarily consider the practical implications
    of our holding, one of which was highlighted by one of our
    sister circuits in Carter v. Sea Land Services, Inc., 
    816 F.2d 1018
     (5th Cir. 1987). There, the Fifth Circuit stated:
    [N]othing in the statute or the legislative
    history [] requires continuing expressions of
    consent before a magistrate can exercise
    authority under a valid reference. Nor will
    we accept the slippery-slope invitation to
    read into the statute a rule that would allow a
    party to express conditional consent to a
    reference, thereby obtaining what amounts to
    a free shot at a favorable outcome or a veto of
    an unfavorable outcome. Any such rule
    would allow the party to hold the power of
    consent over the magistrate like a sword of
    Damocles, ready to strike the reference
    1
    Indeed, the fact that the magistrate judge submitted findings and
    recommendations to dismiss Torres as a defendant demonstrates that he
    did not have jurisdiction over all proceedings pursuant to § 636(c), but
    only an assignment under § 636(b).
    12                     GILMORE V. LOCKARD
    should the magistrate issue a ruling not quite
    to the party’s liking.
    Id. at 1020–21. Allowing a party to withdraw consent
    without utilizing the good cause standard could indeed allow
    a litigant to “shop” between a magistrate and a district judge.
    The facts of this case suggest that might have been precisely
    what Gilmore sought to do when he filed his motion to
    withdraw after receiving an unfavorable ruling.
    Importantly, however, Carter is distinguishable. There,
    as in almost every case where a court reviews a ruling on a
    motion to withdraw consent, 2 both parties had consented to
    magistrate judge jurisdiction. Id. at 1020. The Carter court
    worried about a litigant seeking to withdraw consent after
    both parties had consented and the magistrate judge had
    made determinative rulings pursuant to § 636(c). Here, by
    contrast, Defendants had not yet consented, and the
    magistrate judge had not made rulings outside of limited
    pretrial motions as provided in § 636(b). The concern over
    forum shopping between a magistrate judge and an Article
    2
    The cases upon which Defendants rely all involved circumstances
    where all parties had consented. See Dixon v. Ylst, 
    990 F.2d 478
    , 480
    (9th Cir. 1993); United States v. Neville, 
    985 F.2d 992
    , 999–1000 (9th
    Cir. 1993). The only case supporting Defendants’ position is Espinoza
    v. Diaz, No. 1:17-cv-00338-SAB (PC), 
    2018 WL 910520
     (E.D. Cal. Feb.
    14, 2018), aff’d on other grounds, 723 F. App’x 488 (9th Cir. 2018),
    where, coincidentally, Magistrate Judge Boone denied a plaintiff’s
    motion to withdraw consent for failure to show good cause. 
    Id. at *1
    .
    Importantly, the plaintiff in Diaz proceeded in front of an Article III
    judge, since the defendants continued to decline consent. 
    Id. at *2
    . Thus,
    plaintiff never appealed Magistrate Judge Boone’s denial of his motion
    to withdraw consent, and so the propriety of that ruling was never
    considered.
    GILMORE V. LOCKARD                             13
    III judge is lessened if the magistrate judge can make only
    nondispositive pretrial rulings. 3
    But if the good cause or extraordinary circumstances
    standard is not required, then how should a court adjudicate
    a motion to withdraw consent in such cases? We conclude
    that this is a decision best left to the district court’s
    discretion, and we note that the majority of courts have
    allowed such withdrawal in similar cases. See, e.g., Osotonu
    v. Ringler, No. CIV S-10-2964 DAD P, 
    2011 WL 1047730
    ,
    at *5 (E.D. Cal. Mar. 18, 2011); Bowman v. Schwarzenegger,
    No. CIV S-07-2164 FCD KJM P, 
    2009 WL 799274
    , at *1
    (E.D. Cal. Mar. 23, 2009), aff’d on other grounds, 334 F.
    App’x 850 (9th Cir. 2009)) (“Because this action has not yet
    been reassigned to the [magistrate judge] for all purposes
    including trial, plaintiff may withdraw his consent without
    demonstrating good cause or extraordinary circumstances”);
    Page, 
    2008 WL 3976933
    , at *2. We find these cases
    instructive. Gilmore, a pro se plaintiff, filed a timely motion
    to withdraw consent. There was no possible prejudice to
    Defendants at the time Gilmore sought withdrawal, nor was
    it inconvenient to the district court since the case had already
    been assigned to District Judge O’Neill. Cf. United States v.
    Mortensen, 
    860 F.2d 948
    , 950 (9th Cir. 1988) (holding, in
    the context of a misdemeanor trial before a magistrate judge
    pursuant to 
    18 U.S.C. § 3401
    (b), that “a withdrawal motion
    is timely when granting the motion would not unduly
    interfere with or delay the proceedings.”). Gilmore filed the
    3
    Moreover, Defendants can scarcely complain about Gilmore’s
    judge-shopping, since Defendants sought to do the very same thing.
    When at last they consented to magistrate judge jurisdiction, they
    expressly limited that consent to Magistrate Judge Boone and purported
    to “reserve the right to consent or decline to consent to any subsequently
    assigned magistrate judge.”
    14                 GILMORE V. LOCKARD
    motion in response to an unfavorable pretrial ruling, but this
    alone does not compel a finding that Gilmore’s consent is
    irrevocable for all later dispositive rulings.
    In summary, a party need not satisfy the good cause or
    extraordinary circumstances standard provided in
    § 636(c)(4) in order to withdraw magistrate judge consent
    before all parties have consented. Because the magistrate
    judge erroneously required such a showing by Gilmore, and
    because under the circumstances his motion to withdraw
    consent should have been granted, we conclude that the
    magistrate judge lacked jurisdiction to conduct the trial.
    II. Substitution of Parties
    The magistrate judge denied Gilmore’s repeated motions
    to substitute Defendant Torres after his death, and dismissed
    Gilmore’s deliberate indifference claim against Torres,
    noting that it would have been futile since the 90-day period
    to substitute under Rule 25(a)(1) had passed.
    “The proper interpretation of Rule 25(a) is a question of
    law that we review de novo.” Barlow v. Ground, 
    39 F.3d 231
    , 233 (9th Cir. 1994). “Factual findings relevant to the
    application of Rule 25(a) are reviewed for clear error.” 
    Id.
    Gilmore first argues that the notification of death was not
    properly served upon Torres’s estate and, therefore, that
    Rule 25(a)(1)’s 90-day window was never triggered.
    Second, Gilmore contends that the magistrate judge
    impermissibly placed the burden on him, an incarcerated pro
    se plaintiff, to provide precise details of Torres’s estate.
    Before addressing Gilmore’s arguments, Defendants
    suggest that Rule 25(a) has no application here because
    personal jurisdiction was never established over Torres, who
    died before service.       Defendants identify a largely
    GILMORE V. LOCKARD                       15
    unanswered question: whether substitution is available if a
    party dies after the suit was filed but before being served
    with process.
    The purpose behind Rule 25(a) suggests that substitution
    remains available after filing and prior to service. Rule 25(a)
    seeks “to inform all interested persons of [a party’s] death so
    that they may take appropriate action.” 
    Id. at 233
     (quoting
    3B Moore’s Federal Practice ¶ 25.06[2] (2d ed. 1991)).
    Although service of summons must be completed before a
    federal court may exercise personal jurisdiction over a party,
    Omni Capital International, Ltd. v. Rudolf Wolff & Co.,
    
    484 U.S. 97
    , 104 (1987), service after substitution would
    still preserve a party’s rights and claims, while ensuring that
    a court has personal jurisdiction over the new, proper party.
    See 7C Charles Alan Wright & Arthur R. Miller, Federal
    Practice and Procedure § 1951 (3d ed. 2007) (“If an action
    was commenced by the filing of a complaint but a party
    named in the complaint dies . . . before being served with
    process, substitution is available, but, as in any instance of
    substitution, process must be served on the new party to
    acquire in personam jurisdiction.”).
    Indeed, the Supreme Court inferred as much more than a
    century ago, finding “no reason why the representative of a
    deceased party should not be brought in by the same
    procedure, whether the death of a party occur before or after
    service,” when interpreting a similar California state
    procedural rule. Ex parte Connaway, 
    178 U.S. 421
    , 431
    (1900). Although our court has not yet extended Connaway
    to the federal rule, we observe that the decisions of various
    out-of-circuit courts imply that such an application is proper.
    See, e.g., Ransom v. Brennan, 
    437 F.2d 513
    , 518 (5th Cir.
    1971) (“[I]f no in personam jurisdiction had been acquired
    over the original party, then the substitution of a new party
    16                    GILMORE V. LOCKARD
    under Rule 25(a)(1) . . . places the substituted party in the
    same position as the original party, i.e., a party to the action,
    but one who must be still served with process to secure in
    personam jurisdiction over him.”) (quoting Bertsch v.
    Canterbury, 
    18 F.R.D. 23
    , 27 (S.D. Cal. 1955)); Lummis v.
    Eighth Jud. Dist. Ct., 
    576 P.2d 272
    , 272–73 (Nev. 1978)
    (“Petitioners construe [Nevada’s analogous Rule 25(a)] to
    require the deceased to be a ‘party’ jurisdictionally before
    the court. . . . Such a restrictive interpretation of the
    identical federal rule has been previously rejected.”). 4
    Relying on the purpose of Rule 25(a)(1), and finding these
    prior cases persuasive, we conclude that Rule 25 applies in
    this case, and proceed to the merits of Gilmore’s appeal.
    Gilmore challenges whether the 90-day substitution
    window was triggered when he received notice from the AG
    of Torres’s death, and whether it was his burden to identify
    Torres’s personal representative or successor. Rule 25(a)
    states:
    If a party dies and the claim is not
    extinguished, the court may order
    substitution of the proper party. A motion for
    substitution may be made by any party or by
    4
    Despite Defendants’ urging, we find Goldlawr, Inc. v. Shubert,
    
    175 F. Supp. 793
     (S.D.N.Y. 1959), unpersuasive. There, the court
    expressed doubt that “Rule 25(a)(1) . . . may be invoked to authorize
    substitution of the executors for a defendant who neither appeared nor
    was served with process.” 
    Id. at 797
    . But it did so in the context of
    whether personal jurisdiction over the original defendant even existed in
    the first place. 
    Id.
     at 795–97. This context distinguishes Goldlawr from
    the case before us. We further find Mizukami v. Buras, 
    419 F.2d 1319
    ,
    1320 (5th Cir. 1969), inapposite since that suit was filed after the
    defendant’s death, and Rule 25(a) presupposes that the deceased was
    already a party in the action prior to death.
    GILMORE V. LOCKARD                       17
    the decedent’s successor or representative. If
    the motion is not made within 90 days after
    service of a statement noting the death, the
    action by or against the decedent must be
    dismissed.
    ...
    A motion to substitute, together with a notice
    of hearing, must be served on the parties as
    provided in Rule 5 and on nonparties as
    provided in Rule 4. A statement noting death
    must be served in the same manner.
    Fed. R. Civ. P. 25(a)(1), (3) (emphases added). Rule 25(a)
    thus “requires two affirmative steps in order to trigger the
    running of the 90 day period. First, a party must formally
    suggest the death of the party upon the record. Second, the
    suggesting party must serve other parties and nonparty
    successors or representatives of the deceased with a
    suggestion of death in the same manner as required for
    service of the motion to substitute.” Barlow, 
    39 F.3d at 233
    (emphasis added) (citations omitted). In Barlow, the
    defendants filed a suggestion of death after the plaintiff died,
    but did not serve it on the plaintiff’s easily ascertainable
    estate. 
    Id. at 232
    . We held that the suggestion of death did
    not trigger the 90-day window of Rule 25(a)(1), since the
    rule requires that the “statement noting death must be served
    in the same manner” as the motion to substitute—“on the
    parties . . . and on nonparties.” Fed. R. Civ. P. 25(a)(1), (3).
    In Barlow, we did not reach the question of whether “the
    suggestion of death [must] be served upon the nonparty
    successors or representatives of the estate when the
    appropriate persons could not be ascertained at the time the
    18                 GILMORE V. LOCKARD
    suggestion of death was made.” 
    39 F.3d at 234
    . Here, both
    parties appear to agree that the successors or representatives
    of Torres’s estate were not easily ascertainable. But
    although Barlow did not answer this key question, other
    circuits have suggested that nonparty successors or
    representatives of the deceased party must be personally
    served—or, at a minimum, identified—in order to trigger the
    90-day period. See Fariss v. Lynchburg Foundry, 
    769 F.2d 958
    , 962 (4th Cir. 1985) (“Rule 25(a)(1) directs that both
    parties and appropriate nonparties be served with the
    suggestion of death to commence the 90-day substitution
    period, for the rule seeks ‘to assure the parties to the action
    and other concerned persons of notice of the death so that
    they may take appropriate action to make substitution for the
    deceased party.’”) (quoting 3B J. Moore & J. Kennedy,
    Moore’s Federal Practice ¶ 25.06 (2d ed. 1982)); Rende v.
    Kay, 
    415 F.2d 983
    , 985–86 (D.C. Cir. 1969) (“[T]he Rule,
    as amended, cannot fairly be construed . . . to make
    [decedent’s counsel’s] suggestion of death operative to
    trigger the 90-day period even though he was neither a
    successor nor representative of the deceased, and gave no
    indication of what person was available to be named in
    substitution as a representative of the deceased. [Such a]
    construction would open the door to a tactical maneuver to
    place upon the plaintiff the burden of locating the
    representative of the estate within 90 days.” (footnote
    omitted)); but see Unicorn Tales, Inc. v. Banerjee, 
    138 F.3d 467
    , 470 (2d Cir. 1998) (“The rule does not require that the
    statement identify the successor or legal representative; it
    merely requires that the statement of death be served on the
    involved parties.”).
    In light of Rule 25(a)’s function, these cases attempted,
    with varying results, to balance the importance of notice to
    both parties and nonparties—which ensures that rights and
    GILMORE V. LOCKARD                             19
    causes of action are protected—with the burden of providing
    such notice. In Barlow and Fariss, the successors or
    representatives were easily ascertainable when the
    respective suggestions of death were provided, and so the
    courts found it appropriate to require such notice in order to
    trigger the 90-day period. In Rende, the D.C. Circuit was
    particularly concerned with placing the burden on a plaintiff
    to identify the defendant’s successor or representative after
    defendant’s counsel filed a suggestion of death. The D.C.
    Circuit ultimately held that the suggestion of death must
    identify the representative or successor before the 90-day
    period is triggered. 
    415 F.2d at
    985–86. Finally, in Unicorn
    Tales, the Second Circuit disagreed with the D.C. Circuit and
    found a suggestion of death sufficient to trigger the 90-day
    window, even if no successor or representative was
    identified, because Rule 6(b) allows time extensions for a
    party to discover such individuals. 
    138 F.3d at 470
    .
    Finding Rende to be better reasoned, we hold that the
    AG’s notice of death did not trigger the 90-day window. The
    AG neither served notice to any nonparties, nor identified
    such nonparties. Either circumstance would have put
    Gilmore on notice as to Torres’s successor or personal
    representative, information that he ultimately struggled to
    obtain despite use of limited discovery and repeated
    motions. 5 Whether or not the AG was actually Torres’s
    counsel, she was significantly better positioned than
    Gilmore to ascertain Torres’s successor since Defendants
    Lopez and Hightower were indisputably her clients, and
    given her existing relationship with the California
    Department of Corrections and Rehabilitation (CDCR).
    Shifting the burden to Gilmore to identify Torres’s successor
    5
    These repeated motions are a fairly clear indication that Rule 6(b)
    extensions would not have assisted Gilmore in obtaining the information.
    20                  GILMORE V. LOCKARD
    or representative would defeat the purpose of Rule 25(a): to
    preserve parties’ rights and causes of action when a party
    dies. As the D.C. Circuit correctly observed in Rende, this
    purpose would not be served by allowing Defendants to
    place Gilmore at a tactical disadvantage, struggling to
    identify Torres’s successors or personal representatives
    within the 90-day deadline.
    Furthermore, nothing in Barlow suggests that where the
    party filing the suggestion of death has not yet confirmed the
    proper party for substitution, the burden of finding and
    serving the substituted party should necessarily shift to the
    other party. Instead, Barlow is better understood as
    interpreting the 90-day rule judiciously: where a party files
    a suggestion of death, it must do so in a manner that puts all
    interested parties and nonparties on notice of their claims in
    order to trigger the 90-day window. In that case, we required
    defense counsel to serve plaintiff’s easily identifiable estate.
    Here, we require, at a minimum, identification of Torres’s
    successor or personal representative by Defendants, given
    that they were much better suited than Gilmore to identify
    the proper parties.
    Accordingly, because we hold that the magistrate judge
    erred by placing the burden on Gilmore to identify Torres’s
    successor or personal representative, we conclude that Rule
    25(a)’s 90-day window was not triggered. We therefore
    reverse dismissal of Torres as a defendant, and we reverse
    the dismissal of Gilmore’s deliberate indifference claim.
    Defendants argue that substitution of Mrs. Torres at this
    stage, if she is indeed the proper party, would be futile due
    to the statute of limitations, as well as unduly burdensome.
    But substitution would not be futile.             Defendants
    misunderstand the effect of a Rule 25(a) substitution—Mrs.
    Torres would not be a “new” party. Instead, the claim
    GILMORE V. LOCKARD                       21
    against Torres would survive because it was timely filed
    before his death, and thus would relate back to the date of
    the suit’s filing. See Flores v. City of Westminster, 
    873 F.3d 739
    , 761 (9th Cir. 2017). Defendants’ argument that
    substitution would be unduly burdensome might be
    persuasive, but it is not one that we are able to adjudicate. It
    is instead a matter for the district court to consider on
    remand.
    III.    Expert Testimonies
    Because we reverse the jury verdict and remand for
    further proceedings based on the magistrate judge’s lack of
    jurisdiction, we need not consider Gilmore’s evidentiary
    challenges in detail. However, “for the guidance of the trial
    court on remand,” United States v. Mayans, 
    17 F.3d 1174
    ,
    1184 (9th Cir. 1994), we note that Officer Jalani Hunter was
    permitted to offer testimony whose “probative value is
    substantially outweighed by [the] danger of . . . unfair
    prejudice.” Fed. R. Evid. 403. While Hunter’s testimony
    about Gilmore’s alleged gang affiliation was largely
    unobjectionable, his testimony about gangs to which
    Gilmore had no connection whatsoever—including
    organizations such as the Aryan Brotherhood and the
    Mexican Mafia which have historic and public notoriety—
    was of “marginal, if any, probative value.” Estate of Diaz v.
    City of Anaheim, 
    840 F.3d 592
    , 603 (9th Cir. 2016). Still
    more inflammatory was Hunter’s statement to the jury that
    “the local streets that you guys live on, these hits that are
    murders or whatever that’s taking place out on the street . . .
    [are] taking place because of members housed in the
    [CDCR].” Testimony of unrelated gang activity outside the
    prison walls provided no useful information in this case
    involving an altercation within prison walls. Given that
    “[o]ur cases make it clear that evidence relating to gang
    22                GILMORE V. LOCKARD
    involvement will almost always be prejudicial,” Kennedy v.
    Lockyer, 
    379 F.3d 1041
    , 1055 (9th Cir. 2004), the minimal
    probative value of Hunter’s testimony is easily outweighed
    by the tremendous risk of unfair prejudice to Gilmore and so
    it should be excluded if the case is retried.
    CONCLUSION
    We reverse the jury verdict, finding that the magistrate
    judge did not have jurisdiction over trial proceedings
    pursuant to § 636(c). We further reverse dismissal of Torres
    as a Defendant, finding the 90-day window under Rule 25(a)
    was never triggered, and we reverse the dismissal of
    Gilmore’s deliberate indifference claim. We remand for
    further proceedings consistent with this opinion.
    REVERSED AND REMANDED.
