    CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
    THE NINTH CIRCUIT
    No. 16–369.      Argued March 22, 2017—Decided May 30, 2017
    The Los Angeles County Sheriff’s Department received word from a
    confidential informant that a potentially armed and dangerous parol-
    ee-at-large had been seen at a certain residence. While other officers
    searched the main house, Deputies Conley and Pederson searched
    the back of the property where, unbeknownst to the deputies, re-
    spondents Mendez and Garcia were napping inside a shack where
    they lived. Without a search warrant and without announcing their
    presence, the deputies opened the door of the shack. Mendez rose
    from the bed, holding a BB gun that he used to kill pests. Deputy
    Conley yelled, “Gun!” and the deputies immediately opened fire,
    shooting Mendez and Garcia multiple times. Officers did not find the
    parolee in the shack or elsewhere on the property.
    Mendez and Garcia sued Deputies Conley and Pederson and the
    County under 
    42 U.S. C
    . §1983, pressing three Fourth Amendment
    claims: a warrantless entry claim, a knock-and-announce claim, and
    an excessive force claim. On the first two claims, the District Court
    awarded Mendez and Garcia nominal damages. On the excessive
    force claim, the court found that the deputies’ use of force was rea-
    sonable under Graham v. Connor, 
    490 U.S. 386
    , but held them liable
    nonetheless under the Ninth Circuit’s provocation rule, which makes
    an officer’s otherwise reasonable use of force unreasonable if (1) the
    officer “intentionally or recklessly provokes a violent confrontation”
    and (2) “the provocation is an independent Fourth Amendment viola-
    tion,” Billington v. Smith, 
    292 F.3d 1177
    , 1189. On appeal, the
    Ninth Circuit held that the officers were entitled to qualified immun-
    ity on the knock-and-announce claim and that the warrantless entry
    violated clearly established law. It also affirmed the District Court’s
    2               COUNTY OF LOS ANGELES v. MENDEZ
    Syllabus
    application of the provocation rule, and held, in the alternative, that
    basic notions of proximate cause would support liability even without
    the provocation rule.
    Held: The Fourth Amendment provides no basis for the Ninth Circuit’s
    “provocation rule.” Pp. 5–10.
    (a) The provocation rule is incompatible with this Court’s excessive
    force jurisprudence, which sets forth a settled and exclusive frame-
    work for analyzing whether the force used in making a seizure com-
    plies with the Fourth Amendment. See 
    Graham, supra, at 395
    . The
    operative question in such cases is “whether the totality of the cir-
    cumstances justifie[s] a particular sort of search or seizure.” Tennes-
    see v. Garner, 
    471 U.S. 1
    , 8–9. When an officer carries out a seizure
    that is reasonable, taking into account all relevant circumstances,
    there is no valid excessive force claim. The provocation rule, howev-
    er, instructs courts to look back in time to see if a different Fourth
    Amendment violation was somehow tied to the eventual use of force,
    an approach that mistakenly conflates distinct Fourth Amendment
    claims. The proper framework is set out in Graham. To the extent
    that a plaintiff has other Fourth Amendment claims, they should be
    analyzed separately.
    The Ninth Circuit attempts to cabin the provocation rule by defin-
    ing a two-prong test: First, the separate constitutional violation must
    “creat[e] a situation which led to” the use of force; and second, the
    separate constitutional violation must be committed recklessly or in-
    tentionally. 
    815 F.3d 1178
    , 1193. Neither limitation, however,
    solves the fundamental problem: namely, that the provocation rule is
    an unwarranted and illogical expansion of Graham. In addition, each
    limitation creates problems of its own. First, the rule relies on a
    vague causal standard. Second, while the reasonableness of a search
    or seizure is almost always based on objective factors, the provocation
    rule looks to the subjective intent of the officers who carried out the
    seizure.
    There is no need to distort the excessive force inquiry in this way in
    order to hold law enforcement officers liable for the foreseeable con-
    sequences of all their constitutional torts. Plaintiffs can, subject to
    qualified immunity, generally recover damages that are proximately
    caused by any Fourth Amendment violation. See, e.g., Heck v.
    Humphrey, 
    512 U.S. 477
    , 483. Here, if respondents cannot recover
    on their excessive force claim, that will not foreclose recovery for in-
    juries proximately caused by the warrantless entry. Pp. 5–10.
    (b) The Ninth Circuit’s proximate-cause holding is similarly taint-
    ed. Its analysis appears to focus solely on the risks foreseeably asso-
    ciated with the failure to knock and announce—the claim on which
    the court concluded that the deputies had qualified immunity—
    Cite as: 581 U. S. ____ (2017)                   3

    rather than the warrantless entry. On remand, the court should re-
    visit the question whether proximate cause permits respondents to
    recover damages for their injuries based on the deputies’ failure to
    secure a warrant at the outset. Pp. 10–11.

    PETITIONERS v. ANGEL MENDEZ, ET AL.
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [May 30, 2017]
    JUSTICE ALITO delivered the opinion of the Court.
    If law enforcement officers make a “seizure” of a person
    using force that is judged to be reasonable based on a
    consideration of the circumstances relevant to that deter-
    mination, may the officers nevertheless be held liable for
    injuries caused by the seizure on the ground that they
    committed a separate Fourth Amendment violation that
    contributed to their need to use force? The Ninth Circuit
    has adopted a “provocation rule” that imposes liability in
    such a situation.
    We hold that the Fourth Amendment provides no basis
    for such a rule. A different Fourth Amendment violation
    cannot transform a later, reasonable use of force into an
    unreasonable seizure.
    I
    A
    In October 2010, deputies from the Los Angeles County
    Sheriff ’s Department were searching for a parolee-at-large
    named Ronnie O’Dell. A felony arrest warrant had been
    issued for O’Dell, who was believed to be armed and dan-
    gerous and had previously evaded capture. Findings of
    2           COUNTY OF LOS ANGELES v. MENDEZ
    Opinion of the Court
    Fact and Conclusions of Law, No. 2:11–cv–04771 (CD
    Cal.), App. to Pet. for Cert. 56a, 64a. Deputies Christo-
    pher Conley and Jennifer Pederson were assigned to assist
    the task force searching for O’Dell. 
    Id., at 57a–58a.
    The
    task force received word from a confidential informant
    that O’Dell had been seen on a bicycle at a home in Lan-
    caster, California, owned by Paula Hughes, and the offic-
    ers then mapped out a plan for apprehending O’Dell. 
    Id., at 58a.
    Some officers would approach the front door of the
    Hughes residence, while Deputies Conley and Pederson
    would search the rear of the property and cover the back
    door of the residence. 
    Id., at 59a.
    During this briefing, it
    was announced that a man named Angel Mendez lived in
    the backyard of the Hughes home with a pregnant woman
    named Jennifer Garcia (now Mrs. Jennifer Mendez). 
    Ibid. Deputy Pederson heard
    this announcement, but at trial
    Deputy Conley testified that he did not remember it. 
    Ibid. When the officers
    reached the Hughes residence around
    midday, three of them knocked on the front door while
    Deputies Conley and Pederson went to the back of the
    property. 
    Id., at 63a.
    At the front door, Hughes asked if
    the officers had a warrant. 
    Ibid. A sergeant responded
    that they did not but were searching for O’Dell and had a
    warrant for his arrest. 
    Ibid. One of the
    officers heard
    what he thought were sounds of someone running inside
    the house. 
    Id., at 64a.
    As the officers prepared to open
    the door by force, Hughes opened the door and informed
    them that O’Dell was not in the house. 
    Ibid. She was placed
    under arrest, and the house was searched, but
    O’Dell was not found. 
    Ibid. Meanwhile, Deputies Conley
    and Pederson, with guns
    drawn, searched the rear of the residence, which was
    cluttered with debris and abandoned automobiles. 
    Id., at 60a,
    65a. The property included three metal storage sheds
    and a one-room shack made of wood and plywood. 
    Id., at 60a.
    Mendez had built the shack, and he and Garcia had
    Cite as: 581 U. S. ____ (2017)           3
    Opinion of the Court
    lived inside for about 10 months. 
    Id., at 61a.
    The shack
    had a single doorway covered by a blue blanket. 
    Ibid. Amid the debris
    on the ground, an electrical cord ran into
    the shack, and an air conditioner was mounted on the
    side. 
    Id., at 62a.
    A gym storage locker and clothes and
    other possessions were nearby. 
    Id., at 61a.
    Mendez kept a
    BB rifle in the shack for use on rats and other pests. 
    Id., at 62a.
    The BB gun “closely resembled a small caliber
    rifle.” 
    Ibid. Deputies Conley and
    Pederson first checked the three
    metal sheds and found no one inside. 
    Id., at 65a.
    They
    then approached the door of the shack. 
    Id., at 66a.
    Unbe-
    knownst to the officers, Mendez and Garcia were in the
    shack and were napping on a futon. 
    Id., at 67a.
    The
    deputies did not have a search warrant and did not knock
    and announce their presence. 
    Id., at 66a.
    When Deputy
    Conley opened the wooden door and pulled back the blan-
    ket, Mendez thought it was Ms. Hughes and rose from the
    bed, picking up the BB gun so he could stand up and place
    it on the floor. 
    Id., at 68a.
    As a result, when the deputies
    entered, he was holding the BB gun, and it was “point[ing]
    somewhat south towards Deputy Conley.” 
    Id., at 69a.
    Deputy Conley yelled, “Gun!” and the deputies immediately
    opened fire, discharging a total of 15 rounds. 
    Id., at 69a–
    70a. Mendez and Garcia “were shot multiple times and
    suffered severe injuries,” and Mendez’s right leg was later
    amputated below the knee. 
    Id., at 70a.
    O’Dell was not in
    the shack or anywhere on the property. 
    Ibid. B Mendez and
    his wife (respondents here) filed suit under
    Rev. Stat. §1976, 
    42 U.S. C
    . §1983, against petitioners,
    the County of Los Angeles and Deputies Conley and Ped-
    erson. As relevant here, they pressed three Fourth
    Amendment claims. First, they claimed that the deputies
    executed an unreasonable search by entering the shack
    4           COUNTY OF LOS ANGELES v. MENDEZ
    Opinion of the Court
    without a warrant (the “warrantless entry claim”); second,
    they asserted that the deputies performed an unreason-
    able search because they failed to announce their presence
    before entering the shack (the “knock-and-announce
    claim”); and third, they claimed that the deputies effected
    an unreasonable seizure by deploying excessive force in
    opening fire after entering the shack (the “excessive force
    claim”).
    After a bench trial, the District Court ruled largely in
    favor of respondents. App. to Pet. for Cert. 135a–136a.
    The court found Deputy Conley liable on the warrantless
    entry claim, and the court also found both deputies liable
    on the knock-and-announce claim. But the court awarded
    nominal damages for these violations because “the act of
    pointing the BB gun” was a superseding cause “as far as
    damage [from the shooting was] concerned.” App. 238.
    The District Court then addressed respondents’ exces-
    sive force claim. App. to Pet. for Cert. 105a–127a. The
    court began by evaluating whether the deputies used
    excessive force under Graham v. Connor, 
    490 U.S. 386
    (1989). The court held that, under Graham, the deputies’
    use of force was reasonable “given their belief that a man
    was holding a firearm rifle threatening their lives.” App.
    to Pet. for Cert. 108a. But the court did not end its exces-
    sive force analysis at this point. Instead, the court turned
    to the Ninth Circuit’s provocation rule, which holds that
    “an officer’s otherwise reasonable (and lawful) defensive
    use of force is unreasonable as a matter of law, if (1) the
    officer intentionally or recklessly provoked a violent re-
    sponse, and (2) that provocation is an independent consti-
    tutional violation.” 
    Id., at 111a.
    Based on this rule, the
    District Court held the deputies liable for excessive force
    and awarded respondents around $4 million in damages.
    
    Id., at 135a–136a.
      The Court of Appeals affirmed in part and reversed in
    part. 
    815 F.3d 1178
    (CA9 2016). Contrary to the District
    Cite as: 581 U. S. ____ (2017)           5
    Opinion of the Court
    Court, the Court of Appeals held that the officers were
    entitled to qualified immunity on the knock-and-announce
    claim. 
    Id., at 1191–1193.
    But the court concluded that
    the warrantless entry of the shack violated clearly estab-
    lished law and was attributable to both deputies. 
    Id., at 1191,
    1195. Finally, and most important for present
    purposes, the court affirmed the application of the provo-
    cation rule. The Court of Appeals did not disagree with
    the conclusion that the shooting was reasonable under
    Graham; instead, like the District Court, the Court of
    Appeals applied the provocation rule and held the depu-
    ties liable for the use of force on the theory that they had
    intentionally and recklessly brought about the shooting by
    entering the shack without a warrant in violation of clearly
    established 
    law. 815 F.3d, at 1193
    .
    The Court of Appeals also adopted an alternative ra-
    tionale for its judgment. It held that “basic notions of
    proximate cause” would support liability even without the
    provocation rule because it was “reasonably foreseeable”
    that the officers would meet an armed homeowner when
    they “barged into the shack unannounced.” 
    Id., at 1194–
    1195.
    We granted certiorari. 580 U. S. ___ (2016).
    II
    The Ninth Circuit’s provocation rule permits an exces-
    sive force claim under the Fourth Amendment “where an
    officer intentionally or recklessly provokes a violent con-
    frontation, if the provocation is an independent Fourth
    Amendment violation.” Billington v. Smith, 
    292 F.3d 1177
    , 1189 (CA9 2002). The rule comes into play after a
    forceful seizure has been judged to be reasonable under
    Graham. Once a court has made that determination, the
    rule instructs the court to ask whether the law enforce-
    ment officer violated the Fourth Amendment in some
    other way in the course of events leading up to the seizure.
    6           COUNTY OF LOS ANGELES v. MENDEZ
    Opinion of the Court
    If so, that separate Fourth Amendment violation may
    “render the officer’s otherwise reasonable defensive use of
    force unreasonable as a matter of law.” 
    Id., at 1190–1191.
       The provocation rule, which has been “sharply ques-
    tioned” outside the Ninth Circuit, City and County of San
    Francisco v. Sheehan, 575 U. S. ___, ___, n. 4 (2015) (slip
    op., at 14, n. 4), is incompatible with our excessive force
    jurisprudence. The rule’s fundamental flaw is that it uses
    another constitutional violation to manufacture an exces-
    sive force claim where one would not otherwise exist.
    The Fourth Amendment prohibits “unreasonable
    searches and seizures.” “[R]easonableness is always the
    touchstone of Fourth Amendment analysis,” Birchfield v.
    North Dakota, 579 U. S. ___, ___ (2016) (slip op., at 37),
    and reasonableness is generally assessed by carefully
    weighing “the nature and quality of the intrusion on the
    individual’s Fourth Amendment interests against the
    importance of the governmental interests alleged to justify
    the intrusion.” Tennessee v. Garner, 
    471 U.S. 1
    , 8 (1985)
    (internal quotation marks omitted).
    Our case law sets forth a settled and exclusive frame-
    work for analyzing whether the force used in making a
    seizure complies with the Fourth Amendment. See Gra-
    
    ham, 490 U.S., at 395
    . As in other areas of our Fourth
    Amendment jurisprudence, “[d]etermining whether the
    force used to effect a particular seizure is ‘reasonable’ ”
    requires balancing of the individual’s Fourth Amendment
    interests against the relevant government interests. 
    Id., at 396.
    The operative question in excessive force cases is
    “whether the totality of the circumstances justifie[s] a
    particular sort of search or seizure.” 
    Garner, supra, at 8
    –9.
    The reasonableness of the use of force is evaluated
    under an “objective” inquiry that pays “careful attention to
    the facts and circumstances of each particular case.”
    
    Graham, supra, at 396
    . And “[t]he ‘reasonableness’ of a
    particular use of force must be judged from the perspective
    Cite as: 581 U. S. ____ (2017)            7
    Opinion of the Court
    of a reasonable officer on the scene, rather than with the
    20/20 vision of hindsight.” 
    Ibid. “Excessive force claims
    . . . are evaluated for objective reasonableness based upon
    the information the officers had when the conduct oc-
    curred.” Saucier v. Katz, 
    533 U.S. 194
    , 207 (2001). That
    inquiry is dispositive: When an officer carries out a seizure
    that is reasonable, taking into account all relevant cir-
    cumstances, there is no valid excessive force claim.
    The basic problem with the provocation rule is that it
    fails to stop there. Instead, the rule provides a novel and
    unsupported path to liability in cases in which the use of
    force was reasonable. Specifically, it instructs courts to
    look back in time to see if there was a different Fourth
    Amendment violation that is somehow tied to the eventual
    use of force. That distinct violation, rather than the force-
    ful seizure itself, may then serve as the foundation of the
    plaintiff ’s excessive force claim. 
    Billington, supra, at 1190
    (“The basis of liability for the subsequent use of force is
    the initial constitutional violation . . . ”).
    This approach mistakenly conflates distinct Fourth
    Amendment claims. Contrary to this approach, the objec-
    tive reasonableness analysis must be conducted separately
    for each search or seizure that is alleged to be unconstitu-
    tional. An excessive force claim is a claim that a law
    enforcement officer carried out an unreasonable seizure
    through a use of force that was not justified under the
    relevant circumstances. It is not a claim that an officer
    used reasonable force after committing a distinct Fourth
    Amendment violation such as an unreasonable entry.
    By conflating excessive force claims with other Fourth
    Amendment claims, the provocation rule permits excessive
    force claims that cannot succeed on their own terms. That
    is precisely how the rule operated in this case. The Dis-
    trict Court found (and the Ninth Circuit did not dispute)
    that the use of force by the deputies was reasonable under
    Graham. However, respondents were still able to recover
    8             COUNTY OF LOS ANGELES v. MENDEZ
    Opinion of the Court
    damages because the deputies committed a separate
    constitutional violation (the warrantless entry into the
    shack) that in some sense set the table for the use of force.
    That is wrong. The framework for analyzing excessive
    force claims is set out in Graham. If there is no excessive
    force claim under Graham, there is no excessive force
    claim at all. To the extent that a plaintiff has other
    Fourth Amendment claims, they should be analyzed
    separately.*
    The Ninth Circuit’s efforts to cabin the provocation rule
    only undermine it further. The Ninth Circuit appears to
    recognize that it would be going entirely too far to suggest
    that any Fourth Amendment violation that is connected to
    a reasonable use of force should create a valid excessive
    force claim. See, e.g., Beier v. Lewiston, 
    354 F.3d 1058
    ,
    1064 (CA9 2004) (“Because the excessive force and false
    arrest factual inquiries are distinct, establishing a lack of
    probable cause to make an arrest does not establish an
    excessive force claim, and vice-versa”). Instead, that court
    has endeavored to limit the rule to only those distinct
    Fourth Amendment violations that in some sense “pro-
    voked” the need to use force. The concept of provocation,
    ——————
    * Respondents do not attempt to defend the provocation rule. In-
    stead, they argue that the judgment below should be affirmed under
    Graham itself. Graham commands that an officer’s use of force be
    assessed for reasonableness under the “totality of the 
    circumstances.” 490 U.S., at 396
    (internal quotation marks omitted). On respondents’
    view, that means taking into account unreasonable police conduct prior
    to the use of force that foreseeably created the need to use it. Brief for
    Respondents 42–43. We did not grant certiorari on that question, and
    the decision below did not address it. Accordingly, we decline to ad-
    dress it here. See, e.g., McLane Co. v. EEOC, ante, at 11 (“[W]e are a
    court of review, not of first view” (internal quotation marks omitted)).
    All we hold today is that once a use of force is deemed reasonable under
    Graham, it may not be found unreasonable by reference to some sepa-
    rate constitutional violation. Any argument regarding the District
    Court’s application of Graham in this case should be addressed to the
    Ninth Circuit on remand.
    Cite as: 581 U. S. ____ (2017)           9
    Opinion of the Court
    in turn, has been defined using a two-prong test. First,
    the separate constitutional violation must “creat[e] a
    situation which led to” the use of force; second, the sepa-
    rate constitutional violation must be committed recklessly
    or 
    intentionally. 815 F.3d, at 1193
    (internal quotation
    marks omitted).
    Neither of these limitations solves the fundamental
    problem of the provocation rule: namely, that it is an
    unwarranted and illogical expansion of Graham. But in
    addition, each of the limitations creates problems of its
    own. First, the rule includes a vague causal standard. It
    applies when a prior constitutional violation “created a
    situation which led to” the use of force. The rule does not
    incorporate the familiar proximate cause standard. In-
    deed, it is not clear what causal standard is being applied.
    Second, while the reasonableness of a search or seizure is
    almost always based on objective factors, see Whren v.
    United States, 
    517 U.S. 806
    , 814 (1996), the provocation
    rule looks to the subjective intent of the officers who car-
    ried out the seizure. As noted, under the Ninth Circuit’s
    rule, a prior Fourth Amendment violation may be held to
    have provoked a later, reasonable use of force only if the
    prior violation was intentional or reckless.
    The provocation rule may be motivated by the notion
    that it is important to hold law enforcement officers liable
    for the foreseeable consequences of all of their constitu-
    tional torts. See 
    Billington, 292 F.3d, at 1190
    (“[I]f an
    officer’s provocative actions are objectively unreasonable
    under the Fourth Amendment, . . . liability is established,
    and the question becomes . . . what harms the constitu-
    tional violation proximately caused”). However, there is
    no need to distort the excessive force inquiry in order to
    accomplish this objective. To the contrary, both parties
    accept the principle that plaintiffs can—subject to quali-
    fied immunity—generally recover damages that are prox-
    imately caused by any Fourth Amendment violation. See,
    10          COUNTY OF LOS ANGELES v. MENDEZ
    Opinion of the Court
    e.g., Heck v. Humphrey, 
    512 U.S. 477
    , 483 (1994) (§1983
    “creates a species of tort liability” informed by tort princi-
    ples regarding “damages and the prerequisites for their
    recovery” (internal quotation marks omitted)); Memphis
    Community School Dist. v. Stachura, 
    477 U.S. 299
    , 306
    (1986) (“[W]hen §1983 plaintiffs seek damages for viola-
    tions of constitutional rights, the level of damages is ordi-
    narily determined according to principles derived from the
    common law of torts”). Thus, there is no need to dress up
    every Fourth Amendment claim as an excessive force
    claim. For example, if the plaintiffs in this case cannot
    recover on their excessive force claim, that will not fore-
    close recovery for injuries proximately caused by the war-
    rantless entry. The harm proximately caused by these
    two torts may overlap, but the two claims should not be
    confused.

    The Court of Appeals also held that “even without rely-
    ing on [the] provocation theory, the deputies are liable for
    the shooting under basic notions of proximate 
    cause.” 815 F.3d, at 1194
    . In other words, the court apparently con-
    cluded that the shooting was proximately caused by the
    deputies’ warrantless entry of the shack. Proper analysis
    of this proximate cause question required consideration of
    the “foreseeability or the scope of the risk created by the
    predicate conduct,” and required the court to conclude that
    there was “some direct relation between the injury asserted
    and the injurious conduct alleged.” Paroline v. United
    States, 572 U. S. ___, ___ (2014) (slip op., at 7) (internal
    quotation marks omitted).
    Unfortunately, the Court of Appeals’ proximate cause
    analysis appears to have been tainted by the same errors
    that cause us to reject the provocation rule. The court
    reasoned that when officers make a “startling entry” by
    “barg[ing] into” a home “unannounced,” it is reasonably

    Opinion of the Court
    foreseeable that violence may 
    result. 815 F.3d, at 1194
    –
    1195 (internal quotation marks omitted). But this ap-
    pears to focus solely on the risks foreseeably associated
    with the failure to knock and announce, which could not
    serve as the basis for liability since the Court of Appeals
    concluded that the officers had qualified immunity on that
    claim. By contrast, the Court of Appeals did not identify
    the foreseeable risks associated with the relevant constitu-
    tional violation (the warrantless entry); nor did it explain
    how, on these facts, respondents’ injuries were proximately
    caused by the warrantless entry. In other words, the
    Court of Appeals’ proximate cause analysis, like the provo-
    cation rule, conflated distinct Fourth Amendment claims
    and required only a murky causal link between the war-
    rantless entry and the injuries attributed to it. On re-
    mand, the court should revisit the question whether prox-
    imate cause permits respondents to recover damages for
    their shooting injuries based on the deputies’ failure to
    secure a warrant at the outset. See Bank of America Corp.
    v. Miami, ante, at 12 (declining to “draw the precise
    boundaries of proximate cause” in the first instance). The
    arguments made on this point by the parties and by the
    United States as amicus provide a useful starting point for
    this inquiry. See Brief for Petitioners 42–56; Brief for
    Respondents 20–31, 51–59; Reply Brief 17–24; Brief for
    United States as Amicus Curiae 26–32.

    For these reasons, the judgment of the Court of Appeals
    is vacated, and the case is remanded for further proceed-
    ings consistent with this opinion.
    It is so ordered.
