    Citigroup, Inc. v. Abu Dhabi Investment Authority
    UNITED STATES COURT OF APPEALS
    FOR THE SECOND CIRCUIT

    Before:
    WESLEY, HALL, and LYNCH, Circuit Judges.
    Appeal from the district court’s judgment dismissing the complaint of Citigroup, Inc.
    and compelling arbitration pursuant to an arbitration clause contained in the parties’
    contract. We hold that the “extraordinary remedies” authorized by the All Writs Act, 28
    U.S.C. § 1651, do not permit a district court to enjoin an arbitration based on whatever
    claim-preclusive effect may result from the court’s prior judgment when that judgment
    merely confirmed the result of the parties’ earlier arbitration without considering the merits
    of the underlying claims at issue in that arbitration.
    AFFIRMED.

    Dhabi Investment Authority.
    HALL, Circuit Judge:
    This case presents the question of whether the All Writs Act, 28 U.S.C. § 1651(a),
    permits a federal district court to enjoin a second arbitration between parties to a contractual
    arbitration agreement based on what one party asserts is the claim-preclusive effect of a prior
    federal judgment confirming the result of the parties’ earlier arbitration. We hold that the
    “extraordinary remedies” authorized by the All Writs Act cannot be used to enjoin an
    arbitration based on whatever claim-preclusive effect may result from the district court’s
    prior judgment when that judgment merely confirmed the result of the parties’ earlier
    arbitration without considering the merits of the underlying claims at issue in that
    arbitration. We concur with the district court that Appellant Citigroup, Inc. has not
    demonstrated an adequate basis for an extraordinary injunction pursuant to the All Writs Act
    and affirm the judgment dismissing Citigroup’s complaint and compelling arbitration.
    BACKGROUD
    The facts are straightforward. Citigroup, Inc. and the Abu Dhabi Investment
    Authority (“ADIA”) were parties to an Investment Agreement under which ADIA invested
    billions of dollars in Citigroup. The Agreement contained an arbitration clause providing
    that “any dispute that arises out of or relates to the [Agreement], or the breach thereof, . . .
    will be decided through arbitration administered by the American Arbitration Association.”
    J.A. 163. In 2009, ADIA commenced arbitration proceedings pursuant to this clause,
    alleging that Citigroup had diluted the value of its investment by issuing preferred shares to
    other investors. See Abu Dhabi Inv. Auth. v. Citigroup, Inc., No. 12-cv-283, 
    2013 WL 789642
    ,
    at *1 (S.D.N.Y. Mar. 4, 2013). It asserted claims of fraud, securities fraud, negligent
    2
    misrepresentation, breach of fiduciary duty, breach of contract, and breach of the implied
    covenant of good faith and fair dealing. 
    Id. The arbitrators
    rejected ADIA’s claims and
    returned an award in favor of Citigroup after a lengthy and hard-fought proceeding that
    included extensive discovery and a multi-day hearing. 
    Id. Citigroup moved
    in the United
    States District Court for the Southern District of New York for entry of an order confirming
    the award. The district court (Daniels, J.) granted Citigroup’s motion, rejecting ADIA’s
    arguments that the award should be vacated on the grounds that the arbitrators’ choice-of-
    law ruling and two evidentiary rulings were made in manifest disregard of the law and
    prevented ADIA from presenting its case. See 
    id. at *1,
    9. ADIA appealed, and this Court
    affirmed, holding that the arbitrators did not act in manifest disregard of the law or exceed
    their authority. Abu Dhabi Inv. Auth. v. Citigroup, Inc., 557 F. App’x 66, 67–68 (2d Cir. Feb.
    19, 2014).
    In August 2013, while the district court’s confirmation judgment remained pending
    before this Court on appeal, ADIA served Citigroup with a new notice of arbitration
    pursuant to the Investment Agreement, again asserting claims of breach of contract and
    breach of the implied covenant of good faith and fair dealing. Shortly thereafter, Citigroup
    instituted this action pursuant to the Declaratory Judgment Act, the All Writs Act, the
    Federal Arbitration Act (“FAA”), 9 U.S.C. § 1, et seq., and the district court’s “inherent
    authority to protect its proceedings and judgments.” By way of relief, Citigroup sought to
    enjoin the second arbitration on the ground that ADIA’s new claims were barred by the
    doctrine of claim preclusion, or res judicata, because they were or could have been raised in
    3
    the first arbitration.1 Citigroup maintained that the second arbitration constituted an
    “assault” on the district court’s March 2013 judgment confirming the first award, and that
    applying the All Writs Act to enjoin the second arbitration was necessary to protect the
    integrity of that judgment. ADIA moved to dismiss Citigroup’s complaint and to compel
    arbitration.
    The district court (Castel, J.) granted ADIA’s motions. After first flagging the strong
    federal policy favoring arbitration, the district court then pointed to our decision in National
    Union Fire Insurance Co. of Pittsburgh, PA v. Belco Petroleum Corp. (“Belco”), 
    88 F.3d 129
    (2d Cir.
    1996), in which we held that the preclusive effect of a prior arbitration that had been
    confirmed by a state court was to be decided by the arbitrators, not the court. Given our
    holding in Belco, other similar decisions, and the parties’ “broad arbitration clause” governing
    “any dispute that arises out of the” Investment Agreement, the district court held that
    Citigroup’s preclusion defense was properly resolved in arbitration. See Citigroup, Inc. v. Abu
    Dhabi Inv. Auth., No. 13-cv-6073, 
    2013 WL 6171315
    , at *3–5 (S.D.N.Y. Nov. 25, 2013).
    Regarding Citigroup’s request to enjoin the second arbitration pursuant to the All
    Writs Act, the district court first observed that our decision in In re American Express Financial
    Advisors Securities Litigation, 
    672 F.3d 113
    (2d Cir. 2011), “allow[ed] the possibility that, in
    certain circumstances, the All Writs Act could permit a court to enjoin an arbitration.”
    Citigroup, Inc., 
    2013 WL 6171315
    , at *5. The court noted, however, that we had previously
    1 The doctrine of claim preclusion, or res judicata, bars the subsequent litigation of any claims
    that were or could have been raised in a prior action. See Federated Dep’t Stores, Inc. v. Moitie,
    
    452 U.S. 394
    , 398 (1981).
    4
    sanctioned the use of the Act to enjoin arbitration only when the arbitration threatened to
    undermine a longstanding federal consent judgment that encompassed extensive equitable
    relief. See Local 1814 Int’l Longshoremen’s Ass’n, AFL-CIO v. N.Y. Shipping Ass’n, Inc., 
    965 F.2d 1224
    , 1237–38 (2d Cir. 1992). Citigroup’s case, by contrast, presented only “garden-variety
    res judicata concerns” because there was “no separate, ongoing proceeding at risk of being
    undermined” by the second arbitration. Citigroup, Inc., 
    2013 WL 6171315
    , at *5. Accepting
    the argument that application of the All Writs Act was necessary in the circumstances of
    Citigroup’s case, the district court reasoned, would “swallow the Belco rule” because it
    “would apply to virtually any instance where a second arbitration is purportedly precluded by
    a federal court judgment confirming the first arbitration award.” 
    Id. Accordingly, the
    court
    held that there was “no basis for an extraordinary remedy to issue under the All Writs Act.”
    
    Id. at *6.
    Citigroup timely appealed the resulting judgment.
    DISCUSSION
    Here, it is undisputed that two sophisticated parties voluntarily contracted to
    arbitrate “any dispute” arising from or relating to their Investment Agreement. As provided
    for under the FAA, the district court’s March 2013 judgment merely confirmed the result of
    the parties’ earlier arbitration through a limited procedure that did not require consideration
    of the merits of the underlying claims. The sole issue in this appeal is whether the district
    court erred when it refused to enjoin the second arbitration pursuant to the All Writs Act
    5
    based on what Citigroup asserts is the claim-preclusive effect of the March 2013 judgment
    and instead compelled the parties to arbitrate ADIA’s second set of claims.2
    The resolution of this issue implicates competing considerations. On the one hand,
    the FAA expresses “a national policy favoring arbitration when the parties contract for that
    mode of dispute resolution.” Preston v. Ferrer, 
    552 U.S. 346
    , 349 (2008). The FAA’s
    framework, moreover, authorizes the federal courts to conduct only a limited review of
    discrete issues before compelling arbitration, leaving the resolution of all other disputes to
    the arbitrators. See Howsam v. Dean Witter Reynolds, Inc., 
    537 U.S. 79
    , 83–84 (2002). Set
    against these considerations, on the other hand, is the weighty practical concern for the
    integrity of federal judgments that could arise if parties felt free to relitigate in arbitration
    proceedings claims previously resolved by a federal court. See In re Am. Express Fin. Advisors
    Sec. Litig. (“American Express”), 
    672 F.3d 113
    , 140 (2d Cir. 2011). In recognition of this
    concern, several of our sister circuits have held that the All Writs Act, which empowers the
    federal courts to “issue all writs necessary or appropriate in aid of their respective
    jurisdictions,” 28 U.S.C. § 1651(a), permits district courts to enjoin arbitrations that threaten
    to undermine federal judgments. See, e.g., In re Y & A Grp. Sec. Litig., 
    38 F.3d 380
    , 382–83
    (8th Cir. 1994). Borrowing language from the Third Circuit, we have characterized these
    competing considerations as presenting “‘a high order challenge.’” American 
    Express, 672 F.3d at 140
    , 141 n.20 (quoting John Hancock Mut. Life Ins. Co. v. Olick, 
    151 F.3d 132
    , 138 (3d
    2We review de novo the district court’s decision to compel arbitration. See Cap Gemini Ernst
    & Young, U.S., LLC v. Nackel, 
    346 F.3d 360
    , 364 (2d Cir. 2003).
    6
    Cir. 1998)). We now must decide the proper balance that should be struck between them in
    this case.
    In addition to manifesting a policy strongly favoring arbitration when contracted for
    by parties to a dispute, the FAA establishes a “body of federal substantive law of
    arbitrability[] applicable to any arbitration agreement within coverage of the Act,” Moses H.
    Cone Mem. Hosp. v. Mercury Constr. Corp., 
    460 U.S. 1
    , 24 (1983), and also “supplies . . . a
    procedural framework applicable in federal courts,” 
    Preston, 552 U.S. at 349
    . Under this
    framework, most disputes between parties to a binding arbitration agreement are
    “arbitrable,” meaning that they are to be decided by the arbitrators, not the courts. See
    
    Howsam, 537 U.S. at 83
    –84. There is one exception to this general rule: unless the parties
    “unmistakably” provide otherwise, courts are to decide “question[s] of arbitrability.” 
    Id. at 83.
    Such questions include disputes “about whether the parties are bound by a given
    arbitration clause” or “disagreement[s] about whether an arbitration clause in a concededly
    binding contract applies to a particular type of controversy.” 
    Id. at 84.
    All other “questions
    which grow out of the dispute and bear on its final disposition are presumptively not for the
    judge, but for an arbitrator, to decide.” 
    Id. at 84–85
    (internal quotation marks omitted)
    (identifying time limits, notice, laches, and estoppel as examples of arbitrable questions).
    “[A]ny doubts concerning the scope of arbitrable issues should be resolved in favor of
    arbitration, whether the problem at hand is the construction of the contract language itself
    or an allegation of waiver, delay, or a like defense to arbitrability.” Moses H. Cone Mem. 
    Hosp., 460 U.S. at 24
    –25.

    The All Writs Act is a “residual source of authority to issue writs that are not
    otherwise covered by statute.” Penn. Bureau of Corr. v. U.S. Marshals Serv., 
    474 U.S. 34
    , 43
    (1985). Thus, while the Act authorizes a federal court to issue commands that are “necessary
    or appropriate to effectuate or prevent the frustration of orders it has previously issued in its
    exercise of jurisdiction otherwise obtained,” Sheet Metal Contractors Ass’n of N. N.J. v. Sheet
    Metal Workers’ Int’l Ass’n, 
    157 F.3d 78
    , 82 (2d Cir. 1998) (internal quotation marks omitted),
    the remedies permitted under the Act are “extraordinary” and “should not be used simply to
    avoid the inconvenience of following statutory procedures that govern the particular
    circumstances,” United States v. Int’l Bhd. of Teamsters, Chauffeurs, Warehousemen and Helpers of
    Am., AFL-CIO, 
    907 F.2d 277
    , 280 (2d Cir. 1990); see also Chappell & Co. v. Frankel, 
    367 F.2d 197
    , 199–200 (2d Cir. 1966) (observing that the “prerogative writs [codified in § 1651(a)]
    have been reserved for extraordinary circumstances”). We review de novo a district court’s
    interpretation of the All Writs Act, United States v. Schurkman, 
    728 F.3d 129
    , 135 (2d Cir.
    2013), but will overturn its decision to grant or deny an injunction under the Act only upon
    identifying an abuse of discretion, see 
    id. In American
    Express, we considered an injunction that barred investors from
    arbitrating claims against a financial services company that the investors had previously
    released in a federal class action settlement over which the district court retained 
    jurisdiction. 672 F.3d at 118
    –19. Explaining that the FAA did not “explicitly confer on the judiciary the
    authority to . . . enjoin a private arbitration,” we nonetheless concluded that the injunction
    was proper in that case because the company, by entering into the settlement agreement, had
    effectively withdrawn its consent to arbitrate the released claims and the district court had
    8
    retained “exclusive” jurisdiction to implement the terms of that settlement agreement. See 
    id. at 140–41
    & n.20. In so holding, we “pause[d] to note” that some of our sister circuits had
    authorized the use of the All Writs Act to enjoin arbitrations in similar circumstances to
    prevent the relitigation of federal judgments. 
    Id. at 141
    n.20 (citing cases). We found it
    unnecessary to consider whether we agreed with that practice given our conclusion that the
    district court’s authority to enter the injunction flowed from its retention of jurisdiction over
    the settlement agreement. 
    Id. We thus
    left unanswered the question of “whether the
    dictates of the All Writs Act might, in another case without the type of jurisdictional
    retention present [in American Express], give a district court the authority to enjoin arbitration
    to prevent re-litigation.” 
    Id. (internal quotation
    marks omitted).
    In this case the district court did not retain jurisdiction over the March 2013
    judgment, much less in a manner comparable to the court’s retention of jurisdiction over the
    settlement agreement in American Express. Citigroup contends that because American Express
    left unresolved whether the All Writs Act permits courts to enjoin an arbitration in the
    absence of such “jurisdictional retention,” Judge Castel erred when he concluded, in
    Citigroup’s words, that the court “lacked the power to prevent ADIA from frustrating the
    [c]ourt’s final judgment” by bringing new claims that were or could have been raised in the
    parties’ first arbitration. Citigroup Br. 27. We disagree with that assertion. The FAA’s
    policy favoring arbitration and our precedents interpreting that policy indicate that it is the
    arbitrators, not the federal courts, who ordinarily should determine the claim-preclusive
    effect of a federal judgment that confirms an arbitration award. Citigroup, moreover, has
    9
    failed to demonstrate that the circumstances of this case justify use of the federal courts’
    authority codified in the All Writs Act to obtain a different result.
    We reason from our prior decisions interpreting the FAA that the determination of
    the claim-preclusive effect of a prior federal judgment confirming an arbitration award is to
    be left to the arbitrators. In Belco, we held that the claim-preclusive effect of a prior
    arbitration award confirmed by a state court judgment was an issue for the arbitrators to
    decide rather than the federal 
    court. 88 F.3d at 135
    –36. In so holding, we reasoned that
    claim preclusion was not a question of arbitrability because it, like other affirmative defenses
    such as time limits and laches, was a legal defense to the opposing party’s claims and, as
    such, was “itself a component of the dispute on the merits.” 
    Id. Several months
    later, we
    held in United States Fire Ins. Co. v. National Gypsum Co. (“National Gypsum”) that the
    arbitrators, not the court, were also to decide whether the doctrine of issue preclusion, or
    collateral estoppel, barred a party from arbitrating certain issues that had previously been
    resolved in litigation resulting in a federal judgment. 
    101 F.3d 813
    , 816–17 (2d Cir. 1996).
    Noting that Belco involved the preclusive effect of a prior arbitration, we concluded in
    National Gypsum that its reasoning was nonetheless equally applicable to the “issue-preclusive
    effect of a prior judgment” because issue preclusion is also an affirmative defense that is
    “part of the dispute on the merits.” 
    Id. at 817.
    Given our holdings in Belco and National Gypsum that arbitrators are to resolve the
    claim-preclusive effect of an arbitration award confirmed by a state court and the issue-
    preclusive effect of a federal judgment, it is a simple intuitive step to conclude that
    arbitrators should also decide the claim-preclusive effect of a federal judgment confirming an
    10
    arbitral award. This is especially so because Citigroup has not challenged the validity of the
    arbitration clause at issue in this case and that clause, like the one in Belco, is sufficiently
    broad to cover any dispute over whether ADIA’s current claims were or could have been
    raised during the first arbitration. Compare 
    Belco, 88 F.3d at 136
    (dispute concerning
    applicability of claim preclusion sent to arbitrators when the arbitration clause covered “all
    disputes which may arise under or in connection with” the underlying contract), with J.A. at
    163 (arbitration clause covering “any dispute that arises out of or relates to the [Investment
    Agreement], or the breach thereof”). And even if we harbored some doubt as to whether
    the claim preclusion dispute in this case is arbitrable, we would resolve that doubt in favor of
    arbitration. See Moses H. Cone Mem. 
    Hosp., 460 U.S. at 24
    –25.
    Citigroup argues that this case warrants a different result because it, unlike Belco,
    involves the claim-preclusive effect of a prior federal judgment. In support, Citigroup points
    to the various decisions we cited in American Express in which other courts have sanctioned
    the use of the All Writs Act to enjoin arbitrations that threaten federal judgments. See In re
    Y&A 
    Grp., 38 F.3d at 382
    –83 (holding that the district court had authority under the All
    Writs Act to enjoin arbitration to protect its earlier consent judgment where the arbitral
    panel had declined to afford that judgment preclusive effect); Hartley v. Stamford Towers Ltd.
    P’ship, 
    1994 WL 463497
    , at *3–5 (9th Cir. Aug. 26, 1994) (unpublished) (court had authority
    pursuant to the Act to enjoin arbitration when its final judgment approving a class action
    settlement reserved jurisdiction to enforce the settlement and enjoined class members from
    bringing subsequent claims grounded in the same factual basis); Allstate Ins. Co. v. Elzanaty,
    
    929 F. Supp. 2d 199
    , 219–20 (E.D.N.Y. 2013) (temporarily enjoining arbitration pursuant to
    11
    the Act to protect ongoing litigation in federal court after determining that it “would severely
    threaten any judgment of th[e] [c]ourt to have pending arbitrations or future arbitrations
    result in inconsistent rulings”); see also John Hancock Mut. Life Ins. Co. v. Olick, 
    151 F.3d 132
    ,
    137–39 (3d Cir. 1998) (holding that the district court, rather than the arbitrators, should have
    decided the preclusive effect of the district court’s earlier judgment on the merits). There is,
    however one significant difference between the precedent established in the cases to which
    Citigroup cites and the circumstances here. The relevant judgments given preclusive effect
    via the All Writs Act in those cases followed from federal judicial proceedings addressing the
    merits of the underlying claims. Thus, in the cases on which Citigroup relies, the main
    justification given for resorting to the All Writs Act is that the district court that resolved the
    merits of a case is in the best position to protect its judgment because it is the most familiar
    with what it considered and decided in the proceedings leading to that judgment. See, e.g., In
    re Y&A Grp. Sec. 
    Litig., 38 F.3d at 382
    –83 (“The district court, and not the arbitration panel,
    is the best interpreter of its own judgment.”).3
    We need not, and do not, consider whether we agree with this justification because it
    is simply absent from this case. Citigroup seeks to preclude a second arbitration based on
    the district court’s March 2013 confirmation judgment because it fears that the second
    3 The limited scope of Y&A Group is underscored by the concurring opinion of the late
    Judge Richard Arnold, who specifically noted that the final order of the district court
    approving the settlement agreement in that case had specifically enjoined class members
    from brining further claims, a fact he regarded as “dispositive.” Judge Arnold went on to
    note that “[i]n general, when parties agree to submit a matter to arbitration, they contract for
    the arbitrator’s decision on legal questions . . . include[ing] defenses, such as res judicata,”
    and that he did not read the opinion “to hold general that courts may, by injunction, control
    the decision of arbitrators on questions of issue or claim 
    preclusion.” 38 F.3d at 384
    .

    arbitration will give ADIA an opportunity to relitigate the same underlying substantive
    claims that were or could have been raised in the parties’ first arbitration. The district
    court’s March 2013 judgment, however, simply confirmed the arbitration award, which
    ordinarily is “a summary proceeding that merely makes what is already a final arbitration
    award a judgment of the court.” D.H. Blair & Co., Inc. v. Gottdiener, 
    462 F.3d 95
    , 110 (2d Cir.
    2006) (internal quotation marks omitted); see also 9 U.S.C. §§ 10, 11 (setting forth the limited
    statutory grounds under which a district court may vacate or modify an arbitration award);
    Willemijn Houdstermaatschappij, BV v. Standard Microsystems Corp., 
    103 F.3d 9
    , 12 (2d Cir. 1997)
    (“[T]he court’s function in confirming or vacating an arbitration award is severely limited.”
    (internal quotation marks omitted)).4 Indeed, in confirming the award, the district court did
    not review the merits of any of ADIA’s substantive claims or the context in which those
    claims arose. Instead, it considered only whether the arbitration panel’s evidentiary rulings
    and application of New York choice-of-law principles violated the FAA. See generally Abu
    Dhabi Inv. Auth. v. Citigroup, Inc., No. 12-cv-283, 
    2013 WL 789642
    (S.D.N.Y. Mar. 4, 2013).
    Under these circumstances, a district court unfamiliar with the underlying circumstances,
    transactions, and claims, is not the best interpreter of what was decided in the arbitration
    4 Citigroup itself observed in its memorandum of law in support of its motion to confirm the
    award that “[a]rbitration awards are subject to severely limited judicial review” and that,
    under the FAA, “a court must confirm an arbitration award unless it concludes that one of
    the enumerated grounds for refusing to enforce the award is present.” See Abu Dhabi Inv.
    Auth. v. Citigroup Inc., S.D.N.Y. dkt no. 12-cv-283, doc. 28 at 11 (internal quotation marks

    [the] scope and preclusive effect” of that decision). Thus, even assuming, as we stated in
    American Express, that there “might” be circumstances under which the All Writs Act
    authorizes district courts to enjoin arbitration to prevent relitigation of their prior judgments,
    this case does not present them. 6
    5 We note also that the district judge who denied Citigroup’s request to enjoin the second
    arbitration pursuant to the All Writs Act was not the judge who originally confirmed the
    result of the first arbitration. Compare Citigroup, Inc. v. Abu Dhabi Inv. Auth., No. 13-cv-6073,
    
    2013 WL 6171315
    , at *3–5 (S.D.N.Y. Nov. 25, 2013) (Castel, J.), with Abu Dhabi Inv. Auth.,
    
    2013 WL 789642
    , at *1 (Daniels, J.).
    6Citigroup’s claim preclusion argument is premised only on the resolution of ADIA’s
    underlying substantive claims raised in the first arbitration. Citigroup does not argue, in
    other words, that we should give preclusive effect to the district court’s determination in its
    March 2013 decision that the first arbitration panel’s evidentiary rulings and choice-of-law
    decision did not violate the FAA. We express no opinion as to whether the All Writs Act
    would authorize the district court to enjoin an arbitration that threatens to undermine the
    district court’s resolution of one of those issues.
    14
    One additional consideration supports our conclusion. Were we to agree with
    Citigroup that the preclusive effect of federal confirmation judgments should be decided by
    the courts, we would effectively create in this circuit a hierarchy of judgments confirming
    arbitration awards: the claim-preclusive effect of confirmation judgments issued by state
    courts would, pursuant to Belco, always be decided by the arbitrators, while the claim-
    preclusive effect of federal confirmation judgments may be decided by the federal courts
    pursuant to their authority under the All Writs Act. This seems an anomalous result,
    especially because we are required to afford state-court judgments full faith and credit, see 28
    U.S.C. § 1738, and are obliged to accord recognition to the preclusive effect of state court
    judgments, see Allen v. McCurry, 
    449 U.S. 90
    , 95–96 (1980). Citigroup has not explained why
    it is an appropriate use of the All Writs Act’s “extraordinary remedies” to treat state and
    federal confirmation judgments differently. The better rule, we think, is to treat them the
    same and, in line with Belco and National Gypsum, permit the arbitrators to determine the
    preclusive effect of both.
    In a final sally, Citigroup argues that if we do not permit the use of the All Writs Act
    to protect federal judgments confirming arbitration awards, we effectively would be
    relegating those judgments to “second-class status” as compared to federal judgments
    following from proceedings on the merits. This outcome, it posits, would be violative of the
    FAA, which provides that an order confirming an arbitral award “shall have the same force
    and effect, in all respects, as, and be subject to all the provisions of law relating to, a
    judgment in an action.” 9 U.S.C. § 13. But Citigroup’s argument presents a false choice.
    The question before us is not whether federal judgments confirming arbitration awards
    15
    should be given less preclusive “force and effect” than other federal judgments.7 The
    relevant question is instead when, if ever, a federal court’s interest in protecting the integrity
    of prior federal judgments authorizes it to use the All Writs Act to reserve for itself the
    exclusive prerogative to determine the claim-preclusive effect of those judgments. In
    answer, we hold only that when the prior federal judgment merely confirmed an arbitration
    award through a limited procedure that did not involve consideration of the merits of the
    underlying claims, the FAA’s framework favoring the submission of disputes to arbitration
    and our precedents in cases addressing comparable issues preclude a district court from
    using the All Writs Act to enjoin a subsequent arbitration of claims that one party asserts are
    barred by the prior arbitration.
    CONCLUSION
    For the foregoing reasons, we affirm the judgment of the district court.
    7Indeed, Citigroup has made no effort to demonstrate that an arbitration panel would not
    give claim-preclusive effect to the district court’s March 2013 confirmation judgment if
    appropriate.
