Task: sc_issue_10

What follows is an opinion from the Supreme Court of the United States. Your task is to determine the issue of the Court's decision. Determine the issue of the case on the basis of the Court's own statements as to what the case is about. Focus on the subject matter of the controversy rather than its legal basis.

Justice Ginsburg
delivered the opinion of the Court.
Section 4 of the Federal Arbitration Act, 9 U. S. C. §4, authorizes a United States district court to entertain a petition to compel arbitration if the court would have jurisdiction, “save for [the arbitration] agreement,” over “a suit arising out of the controversy between the parties.” We consider in this opinion two questions concerning a district court’s subject-matter jurisdiction over a § 4 petition: Should a district court, if asked to compel arbitration pursuant to §4, “look through” the petition and grant the requested relief if the court would have federal-question jurisdiction over the underlying controversy? And if the answer to that question is yes, may a district court exercise jurisdiction over a § 4 petition when the petitioner’s complaint rests on state law but an actual or potential counterclaim rests on federal law?
The litigation giving rise to these questions began when Discover Bank’s servicing affiliate filed a complaint in Maryland state court. Presenting a claim arising solely under state law, Discover sought to recover past-due charges from one of its credit cardholders, Betty Vaden. Vaden answered and counterclaimed, alleging that Discover’s finance charges, interest, and late fees violated state law. Invoking an arbitration clause in its cardholder agreement with Vaden, Discover then filed a § 4 petition in the United States District Court for the District of Maryland to compel arbitration of Vaden’s counterclaims. The District Court had subject-matter jurisdiction over its petition, Discover maintained, because Vaden’s state-law counterclaims were completely preempted by federal banking law. The District Court agreed and ordered arbitration. Reasoning that a federal court has jurisdiction over a § 4 petition if the parties’ underlying dispute presents a federal question, the Fourth Circuit eventually affirmed.
We agree with the Fourth Circuit in part. A federal court may “look through” a §4 petition and order arbitration if, “save for [the arbitration] agreement,” the court would have jurisdiction over “the [substantive] controversy between the parties.” We hold, however, that the Court of Appeals misidentified the dimensions of “the controversy between the parties.” Focusing on only a slice of the parties’ entire controversy, the court seized on Vaden’s counterclaims, held them completely preempted, and on that basis affirmed the District Court’s order compelling arbitration. Lost from sight was the triggering plea — Discover’s claim for the balance due on Vaden’s account. Given that entirely state-based plea and the established rule that federal-court jurisdiction cannot be invoked on the basis of a defense or counterclaim, the whole “controversy between the parties” does not qualify for federal-court adjudication. Accordingly, we reverse the Court of Appeals’ judgment.
I
This case originated as a garden-variety, state-law-based contract action: Discover sued its cardholder, Vaden, in a Maryland state court to recover arrearages amounting to $10,610.74, plus interest and counsel fees. Vaden’s answer asserted usury as an affirmative defense. Vaden also filed several counterclaims, styled as class actions. Like Discover’s complaint, Vaden’s pleadings invoked only state law: Vaden asserted that Discover’s demands for finance charges, interest, and late fees violated Maryland’s credit laws. See Md. Com. Law Code Ann. §§ 12-506, 12-506.2 (Lexis 2005). Neither party invoked — by notice to the other or petition to the state court — the clause in the credit card agreement providing for arbitration of “any claim or dispute between [Discover and Vaden],” App. 44 (capitalization and bold typeface omitted).
Faced with Vaden’s counterclaims, Discover sought federal-court aid. It petitioned the United States District Court for the District of Maryland for an order, pursuant to § 4 of the Federal Arbitration Act (FAA or Act), 9 U. S. C. § 4, compelling arbitration of Vaden’s counterclaims. Although those counterclaims were framed under state law, Discover urged that they were governed entirely by federal law, specifically, § 27(a) of the Federal Deposit Insurance Act (FDIA), 12 U. S. C. § 1831d(a). Section 27(a) prescribes the interest rates state-chartered, federally insured banks like Discover can charge, “notwithstanding any State constitution or statute which is hereby preempted.” This provision, Discover maintained, was completely preemptive, i. e., it superseded otherwise applicable Maryland law, and placed Vaden’s counterclaims under the exclusive governance of the FDIA. On that basis, Discover asserted, the District Court had authority to entertain the § 4 petition pursuant to 28 U. S. C. § 1331, which gives federal courts jurisdiction over cases “arising under” federal law.
The District Court granted Discover’s petition, ordered arbitration, and stayed Vaden’s prosecution of her counterclaims in state court pending the outcome of arbitration. App. to Pet. for Cert. 89a-90a. On Vaden’s initial appeal, the Fourth Circuit inquired whether the District Court had federal-question jurisdiction over Discover’s §4 petition. To make that determination, the Court of Appeals instructed, the District Court should “look through” the §4 petition to the substantive controversy between the parties. 396 F. 3d 366, 369, 373 (2005). The appellate court then remanded the case for an express determination whether that controversy presented “a properly invoked federal question.” Id., at 373.
On remand, Vaden “coneede[d] that the FDIA completely preempts any state claims against a federally insured bank.” 409 F. Supp. 2d 632, 636 (Md. 2006). Accepting this concession, the District Court expressly held that it had federal-question jurisdiction over Discover^ §4 petition and again ordered arbitration. Id., at 634-636, 639. In this second round, the Fourth Circuit affirmed, dividing 2 to 1. 489 F. 3d 594 (2007).
Recognizing that “a party may not create jurisdiction by concession,” id., at 604, n. 10, the Fourth Circuit majority conducted its own analysis of FDIA § 27(a), ultimately concluding that the provision completely preempted state law and therefore governed Vaden’s counterclaims. This Court’s decision in Holmes Group, Inc. v. Vornado Air Circulation Systems, Inc., 535 U. S. 826 (2002), the majority recognized, held that federal-question jurisdiction depends on the contents of a well-pleaded complaint, and may not be predicated on counterclaims. 489 F. 3d, at 600, n. 4. Nevertheless, the majority concluded, the complete preemption doctrine is paramount, “overriding] such fundamental cornerstones of federal subject-matter jurisdiction as the well-pleaded complaint rule.” Ibid, (quoting 14B C. Wright, A. Miller, & E. Cooper, Federal Practice and Procedure §3722.1, p. 511 (3d ed. 1998) (hereinafter Wright & Miller)).
The dissenting judge considered Holmes Group dispositive. As § 27(a) of the FDIA formed no part of Discover’s complaint, but came into the case only as a result of Vaden’s responsive pleadings, the dissent reasoned, “[tjhere was no ‘properly invoked federal question’ in the underlying state ease.” 489 F. 3d, at 610.
We granted certiorari, 552 U. S. 1256 (2008), in view of the conflict among lower federal courts on whether district courts, petitioned to order arbitration pursuant to §4 of the FAA, may “look through” the petition and examine the parties’ underlying dispute to determine whether federal-question jurisdiction exists over the §4 petition. Compare Wisconsin v. Ho-Chunk Nation, 463 F. 3d 655, 659 (CA7 2006) (in determining jurisdiction over a §4 petition, the court may not “look through” the petition and focus on the underlying dispute); Smith Barney, Inc. v. Sarver, 108 F. 3d 92, 94 (CA6 1997) (same); Westmoreland Capital Corp. v. Findlay, 100 F. 3d 263, 267-269 (CA2 1996) (same); and Prudential-Bache Securities, Inc. v. Fitch, 966 F. 2d 981, 986-989 (CA5 1992) (same), with Community Stats Bank v. Strong, 485 F. 3d 597, 605-606 (court may “look through” the petition and train on the underlying dispute), vacated, reh’g en banc granted, 508 F. 3d 576 (CA11 2007); and 396 F. 3d, at 369-370 (case below) (same).
As this case shows, if the underlying dispute is the proper focus of a §4 petition, a further question may arise. The dispute brought to state court by Discover concerned Va-den’s failure to pay over $10,000 in past-due credit card charges. In support of that complaint, Discover invoked no federal law. When Vaden answered and counterclaimed, however, Discover asserted that federal law, specifically § 27(a) of the FDIA, displaced the state laws on which Vaden relied. What counts as the underlying dispute in a case so postured? May Discover invoke § 4, not on the basis of its own complaint, which had no federal element, but on the basis of counterclaims asserted by Vaden? To answer these questions, we first review relevant provisions of the FAA, 9 U. S. C. § 1 et seq., and controlling tenets of federal jurisdiction.
II
In 1925, Congress enacted the FAA “[t]o overcome judicial resistance to arbitration,” Buckeye Check Cashing, Inc. v. Cardegna, 546 U. S. 440, 443 (2006), and to declare “ ‘a national policy favoring arbitration’ of claims that parties contract to settle in that manner,” Preston v. Ferrer, 552 U. S. 346, 353 (2008) (quoting Southland Corp. v. Keating, 465 U. S. 1, 10 (1984)). To that end, §2 provides that arbitration agreements in contracts “involving commerce” are “valid, irrevocable, and enforceable.” 9 U. S. C. §2. Section 4 — the section at issue here — provides for United States district court enforcement of arbitration agreements. Petitions to compel arbitration, §4 states, may be brought before “any United States district court which, save for such agreement, would have jurisdiction under title 28... of the subject matter of a suit arising out of the controversy between the parties.” See supra, at 55, n. 3.
The “body of federal substantive law” generated by elaboration of FAA §2 is equally binding on state and federal courts. Southland, 465 U. S., at 12 (quoting Moses H. Cone Memorial Hospital v. Mercury Constr. Corp., 460 U. S. 1, 25, n. 32 (1983)); accord Allied-Bruce Terminix Cos. v. Dobson, 513 U. S. 265, 271-272 (1995). “As for jurisdiction over controversies touching arbitration,” however, the Act is “something of an anomaly” in the realm of federal legislation: It “bestow[s] no federal jurisdiction but rather requires] [for access to a federal forum] an independent jurisdictional basis” over the parties’ dispute. Hall Street Associates, L. L. C. v. Mattel, Inc., 552 U. S. 576, 581-582 (2008) (quoting Moses H. Cone, 460 U. S., at 25, n. 32). Given the substantive supremacy of the FAA, but the Act’s nonjurisdietional cast, state courts have a prominent role to play as enforcers of agreements to arbitrate. See Southland, 465 U. S., at 15; Moses H. Cone, 460 U. S., at 25, and n. 32.
The independent jurisdictional basis Discover relies upon in this case is 28 U. S. C. § 1331, which vests in federal district courts jurisdiction over “all civil actions arising under the Constitution, laws, or treaties of the United States.” Under the longstanding well-pleaded complaint rule, however, a suit “arises under” federal law “only when the plaintiff’s statement of his own cause of action shows that it is based upon [federal law].” Louisville & Nashville R. Co. v. Mottley, 211 U. S. 149, 152 (1908). Federal jurisdiction cannot be predicated on an actual or anticipated defense: “It is not enough that the plaintiff alleges some anticipated defense to his cause of action and asserts that the defense is invalidated by some provision of [federal law].” Ibid.
Nor can federal jurisdiction rest upon an actual or anticipated counterclaim. We so ruled, emphatically, in Holmes Group, 535 U. S. 826. Without dissent, the Court held in Holmes Group that a federal counterclaim, even when compulsory, does not establish “arising under” jurisdiction. Adhering assiduously to the well-pleaded complaint rule, the Court observed, inter alia, that it would undermine the clarity and simplicity of that rule if federal courts were obliged to consider the contents not only of the complaint but also of responsive pleadings in determining whether a case “arises under” federal law. Id., at 832. See also id., at 830 (“[T]he well-pleaded complaint rule, properly understood, [does not] allo[w] a counterclaim to serve as the basis for a district court’s ‘arising under’ jurisdiction.”); Franchise Tax Bd. of Cal. v. Construction Laborers Vacation Trust for Southern Cal, 463 U. S. 1, 10, n. 9 (1983) (“The well-pleaded complaint rule applies to the original jurisdiction of the district courts as well as to their removal jurisdiction.”).
A complaint purporting to rest on state law, we have recognized, can be recharacterized as one “arising under” federal law if the law governing the complaint is exclusively federal. See Beneficial Nat. Bank v. Anderson, 539 U. S. 1, 8 (2003). Under this so-called “complete-preemption doctrine,” a plaintiff’s “state cause of action [may be recast] as a federal claim for relief, making [its] removal [by the defendant] proper on the basis of federal question jurisdiction.” 14B Wright & Miller §3722.1, p. 511. A state-law-based counterclaim, however, even if similarly susceptible to re-characterization, would remain nonremovable. Under our precedent construing §1331, as just explained, counterclaims, even if they rely exclusively on federal substantive law, do not qualify a case for federal-court cognizance.
Ill
Attending to the language of the FAA and the above-described jurisdictional tenets, we approve the “look through” approach to this extent: A federal court may “look through” a § 4 petition to determine whether it is predicated on an action that “arises under” federal law; in keeping with the well-pleaded complaint rule as amplified in Holmes Group, however, a federal court may not entertain a §4 petition based on the contents, actual or hypothetical, of a counterclaim.
A
The text of §4 drives our conclusion that a federal court should determine its jurisdiction by “looking through” a §4 petition to the parties’ underlying substantive controversy. We reiterate § 4’s relevant instruction: When one party seeks arbitration pursuant to a written agreement and the other resists, the proponent of arbitration may petition for an order compelling arbitration in
“any United States district court which, save for [the arbitration] agreement, would have jurisdiction under title 28, in a civil action or in admiralty of the subject matter of a suit arising out of the controversy between the parties.” 9 U. S. C. §4.
The phrase “save for [the arbitration] agreement” indicates that the district court should assume the absence of the arbitration agreement and determine whether it “would have jurisdiction under title 28” without it. See 396 F. 3d, at 369, 372 (ease below). Jurisdiction over what? The text of §4 refers us to “the controversy between the parties.” That phrase, the Fourth Circuit said, and we agree, is most straightforwardly read to mean the “substantive conflict between the parties.” Id., at 870. See also Moses H. Cone, 460 U. S., at 25, n. 32 (noting in dicta that, to entertain a § 4 petition, a federal court must have jurisdiction over the “underlying dispute”).
The majority of Courts of Appeals to address the question, we acknowledge, have rejected the “look through” approach entirely, as Vaden asks us to do here. See supra, at 57. The relevant “controversy between the parties,” Vaden insists, is simply and only the parties’ discrete dispute over the arbitrability of their claims. She relies, quite reasonably, on the fact that a §4 petition to compel arbitration seeks no adjudication on the merits of the underlying controversy. Indeed, its very purpose is to have an arbitrator, rather than a court, resolve the merits. A § 4 petition, Vaden observes, is essentially a plea for specific performance of an agreement to arbitrate, and it thus presents principally contractual questions: Did the parties validly agree to arbitrate? What issues does their agreement encompass? Has one party dishonored the agreement?
Vaden’s argument, though reasonable, is difficult to square with the statutory language. Section 4 directs courts to determine whether they would have jurisdiction “save for [the arbitration] agreement.” How, then, can a dispute over the existence or applicability of an arbitration agreement be the controversy that counts?
The “save for” clause, courts espousing the view embraced by Vaden respond, means only that the “antiquated and arcane” ouster notion no longer holds sway. Drexel Burnham Lambert, Inc. v. Valenzuela Bock, 696 F. Supp. 957, 961 (SDNY 1988). Adherents to this “ouster” explanation of § 4’s language recall that courts traditionally viewed arbitration clauses as unworthy attempts to “oust” them of jurisdiction; accordingly, to guard against encroachment on their domain, they refused to order specific enforcement of agreements to arbitrate. See H. R. Rep. No. 96, 68th Cong., 1st Sess., 1-2 (1924) (discussed in Dean Witter Reynolds Inc. v. Byrd, 470 U. S. 213, 219-220, and n. 6 (1985)). The “save for” clause, as comprehended by proponents of the “ouster” explanation, was designed to ensure that courts would no longer consider themselves ousted of jurisdiction and would therefore specifically enforce arbitration agreements. See, e. g., Westmoreland, 100 F. 3d, at 267-268, and n. 6 (adopting the “ouster” interpretation advanced in Drexel Burnham Lambert, 696 F. Supp., at 961-963); Strong, 485 F. 3d, at 631 (Marcus, J., specially concurring) (reading §4’s “save for” clause “as instructing the court to ‘set aside’ not the arbitration agreement..., but merely the previous judicial hostility to arbitration agreements”).
We are not persuaded that the “ouster” explanation of § 4’s “save for” clause carries the day. To the extent that the ancient “ouster” doctrine continued to impede specific enforcement of arbitration agreements, §2 of the FAA, the
