    SUMMARY *
    Labor Law / Arbitration / Indian Gaming
    Regulatory Act
    The panel affirmed the district court’s judgment on the
    pleadings in favor of labor union Unite Here Local 30 and
    the district court’s dismissal of a counterclaim brought by
    the Sycuan Band of the Kumeyaay Nation, a federally
    recognized Indian tribe.
    The union brought suit to compel arbitration of its
    allegation that Sycuan violated the labor provisions of the
    parties’ contract respecting the operation of a casino.
    Sycuan opposed arbitration principally because it believed
    that federal labor law preempted its contract with the State
    of California that had required it to enter into the contract
    with Unite Here. In its counterclaim, Sycuan sought a
    declaratory judgment that federal law preempted the labor
    organizing provisions of its contract with California, a
    gaming compact governed by the Indian Gaming Regulatory
    Act. These provisions required Sycuan to adopt and
    maintain a Tribal Labor Relations Ordinance (TLRO), which
    set forth the parties’ agreement about specific labor rights
    for casino employees and included an arbitration provision.
    Unite Here alleged that Sycuan violated the TLRO by
    refusing the union’s demands regarding its intention to
    organize the casino employees.
    The panel held that the district court had original
    jurisdiction over Unite Here’s claims pursuant to 28 U.S.C.

    UNITE HERE LOCAL 30 V. SYCUAN BAND                  3
    § 1331 and 
    29 U.S.C. § 185
    . The panel held that the district
    court had supplemental, but not original, jurisdiction over
    Sycuan’s counterclaim because the Declaratory Judgment
    Act does not confer jurisdiction, and § 301 of the Labor
    Management Relations Act could not confer federal question
    jurisdiction because Sycuan’s challenge was to the
    agreement between Sycuan and the State of California,
    rather than to a contract between an employer and a labor
    organization. The panel held that the district court did not
    abuse its discretion in declining to exercise its supplemental
    jurisdiction because adjudicating the counterclaim in federal
    court would interfere with the arbitrator’s authority. The
    panel concluded that the district court was correct that the
    arbitrator should decide issues of contract validity, and the
    counterclaim rested on an issue of contract validity.
    Accordingly, the district court’s declining to exercise
    supplemental jurisdiction served economy, convenience,
    and fairness. Further, as argued by the State of California in
    its amicus brief, Sycuan did not give the State notice before
    filing the counterclaim, as required by the gaming compact,
    and the State was not a party to this suit seeking to invalidate
    the compact.
    Addressing contract formation, the panel held that Unite
    Here and Sycuan formed an agreement to arbitrate because,
    in the TLRA, Sycuan promised California that if any union
    made certain promises to the tribe, Sycuan would
    automatically enter into a bilateral contract with that union
    adopting the TLRO’s terms. The panel concluded that Unite
    Here made such promises, and a contract was formed,
    because the TLRO was essentially an open-ended offer to
    any union to enter into a bilateral contract.
    With respect to the validity of the contract between
    United Here and Sycuan, the panel declined to address
    4        UNITE HERE LOCAL 30 V. SYCUAN BAND
    Sycuan’s argument that there was no enforceable promise to
    arbitrate because the National Labor Relations Act
    preempted the TLRO. The panel held that the preemption
    argument challenged the contract as a whole and therefore
    was a question for the arbitrator to decide. Rejecting
    Sycuan’s argument that arbitrating NLRA preemption
    would infringe on its tribal sovereign immunity, the panel
    concluded that in the TLRO there was an express waiver of
    sovereign immunity from suit for the purpose of compelling
    arbitration.

    UNITE HERE LOCAL 30 V. SYCUAN BAND                  5
    OPINION
    M. SMITH, Circuit Judge:
    Appellant the Sycuan Band of the Kumeyaay Nation
    (Sycuan or Tribe), a federally recognized Indian tribe, seeks
    the reversal of the district court’s order granting labor union,
    Unite Here Local 30’s (Unite Here), motion for judgment on
    the pleadings with respect to its own complaint and motion
    to dismiss Sycuan’s counterclaim for declaratory relief.
    Unite Here alleges that Sycuan violated the labor provisions
    of a contract between the two parties respecting the
    operation of a casino. The union brought suit to compel
    arbitration of that dispute pursuant to an arbitration clause
    contained in the contract. Sycuan opposes arbitration
    principally because the Tribe believes that federal labor law
    preempts its contract with the State of California that had
    required Sycuan to enter into the contract with Unite Here.
    In a counterclaim, Sycuan seeks a declaratory judgment that
    federal law preempts the labor organizing provisions of the
    agreement with California. We affirm the district court.
    BACKGROUND
    The Sycuan Casino Resort is located on the Tribe’s
    reservation, and revenue from the operation of the casino
    provides funding for tribal governmental services and
    programs for the benefit of the Tribe. Under the rules of the
    federal Indian Gaming Regulatory Act (IGRA), tribes can
    only operate high-stakes casino games (known as Class III
    games) if they sign a gaming compact with the surrounding
    state, and that compact is approved by the Secretary of the
    Interior. 
    25 U.S.C. § 2710
    (d)(1), (3)(B). Tribal-state
    compacts may address “subjects that are directly related to
    the operation of gaming activities,” 
    25 U.S.C. § 2710
    (d)(3)(C)(vii), including labor relations. Coyote
    6         UNITE HERE LOCAL 30 V. SYCUAN BAND
    Valley Band of Pomo Indians v. California (In re Indian
    Gaming Related Cases), 
    331 F.3d 1094
    , 1115–16 (9th Cir.
    2003).
    The State of California and Sycuan entered into a
    compact in 2015 (Compact). Part of the Compact specified
    that Sycuan must adopt and maintain a Tribal Labor
    Relations Ordinance (TLRO), which was included in an
    appendix as a material part of the Compact. The TLRO sets
    forth the parties’ agreement about specific labor rights for
    casino employees and allows labor unions to organize those
    employees. The TLRO also established procedures for
    organizing employees into unions. Section 13 of the TLRO
    provides for arbitration as the dispute resolution procedure
    for all issues arising under the TLRO. In Section 13(e),
    Sycuan waived its sovereign immunity against suits brought
    in state or federal court seeking to compel arbitration.
    Section 7 of the TLRO is at issue in this appeal. In that
    section, Sycuan agreed “that if a union first offers in writing
    that it and its local affiliates will comply with [certain
    provisions of the TLRO] the Tribe shall comply with [other
    provisions].” Included in those provisions is a promise to
    “resolve all issues, including collective bargaining impasses,
    through the binding dispute resolution mechanisms set forth
    in Section 13.” The TLRO further provides that a union
    making these promises “shall be deemed an offer to accept
    the entirety of this Ordinance as a bilateral contract between
    the Tribe and the union, and the Tribe agrees to accept such
    offer.”
    In November 2019, Unite Here made such an offer in a
    letter to Sycuan’s top elected officer indicating the union’s
    intention to organize Sycuan’s casino employees. Unite
    Here then made demands of Sycuan in keeping with the
    terms of the TLRO, but arguably in excess of the rights and
    UNITE HERE LOCAL 30 V. SYCUAN BAND                  7
    obligations provided for in the National Labor Relations Act
    (NLRA). Sycuan refused Unite Here’s demands. Unite
    Here sought to begin arbitration proceedings against Sycuan
    regarding these alleged TLRO violations, but Sycuan
    informed the American Arbitration Association that it would
    not participate in the arbitration. Sycuan stated that it
    believed that portions of the TLRO, including the arbitration
    provision and delegation clause, were not valid because the
    agreement is preempted by the NLRA.
    Unite Here filed a complaint in the United States District
    Court for the Southern District of California alleging that
    Sycuan violated the Compact’s TLRO and asking the court
    to compel arbitration in accordance with the TLRO’s dispute
    resolution provisions. Unite Here first contended that
    pursuant to TLRO Section 7, Sycuan entered into a contract
    with them when Sycuan received Unite Here’s offer letter.
    Unite Here alleged that Sycuan breached their contract by:
    (1) not giving Unite Here a list of employees’ names and
    contact information, (2) telling employees that it opposes
    their unionizing, (3) not allowing Unite Here’s
    representative to enter the casino, and (4) not facilitating the
    dissemination of information from Unite Here to employees.
    Sycuan filed an answer asserting: (a) the NLRA preempts
    the TLRO, (b) there is no binding bilateral agreement
    between Unite Here and Sycuan, (c) parts of the TLRO are
    unenforceable because the terms are not sufficiently definite,
    and (d) Sycuan did not waive its sovereign immunity with
    respect to Unite Here or NLRA preemption. Sycuan also
    filed a counterclaim for declaratory relief claiming that:
    (1) the NLRA preempts portions of the TLRO, so the dispute
    between Sycuan and Unite Here is not arbitrable; and
    (2) Sycuan may still assert its sovereign immunity.
    8        UNITE HERE LOCAL 30 V. SYCUAN BAND
    Unite Here filed a motion to dismiss the counterclaim
    asking the court to decline supplemental jurisdiction over the
    counterclaim for prudential reasons and a motion for
    judgment on the pleadings to compel Sycuan to participate
    in arbitration. Sycuan opposed both motions arguing, among
    other things, that: (1) Sycuan and Unite Here did not
    mutually and voluntarily enter into an agreement to arbitrate
    the dispute at issue; (2) the contract between Sycuan and
    Unite Here is unenforceable because it lacks sufficiently
    definite terms and constitutes an “agreement to agree;” and
    (3) Sycuan did not waive its sovereign immunity to suit with
    respect to Unite Here or the claims alleged.
    The district court granted Unite Here’s motion for
    judgment on the pleadings and dismissed Sycuan’s
    counterclaim. The district court also concluded that there is
    a bilateral contract between Sycuan and Unite Here in which
    both agreed to comply with the arbitration provision of the
    TLRO, and that the remaining disputes must be decided by
    the arbitrator.
    ANALYSIS
    I. Standard of Review
    A district court must grant a motion for judgment on the
    pleadings when there is no issue of material fact, and the
    moving party is entitled to judgment as a matter of law.

    We review for abuse of discretion a district court’s decision
    to exercise or not exercise supplemental jurisdiction.
    Carlsbad Tech., Inc. v. HIF Bio, Inc., 
    556 U.S. 635
    , 639
    (2009).
    II. Jurisdiction
    We have appellate jurisdiction pursuant to 
    28 U.S.C. § 1291
    . The district court had original jurisdiction over
    Unite Here’s claims pursuant to 
    28 U.S.C. § 1331
     and
    
    29 U.S.C. § 185
    .
    The district court correctly concluded that it had
    supplemental, but not original, jurisdiction over Sycuan’s
    counterclaim, and did not abuse its discretion in declining to
    exercise that jurisdiction. District courts have supplemental
    jurisdiction over “claims that are so related to claims in the
    action within such original jurisdiction that they form part of
    the same case or controversy.” 
    28 U.S.C. § 1367
    (a). In its
    counterclaim, Sycuan seeks a declaratory judgment that the
    NLRA preempts inconsistent portions of the TLRO. The
    legal and factual issues in Unite Here’s claims and Sycuan’s
    counterclaim are sufficiently similar that the district court
    did have supplemental jurisdiction because they form a part
    of the same case or controversy concerning the meaning and
    effect of the TLRO.
    Sycuan argues, however, that the district court abused its
    discretion in declining to exercise supplemental jurisdiction
    over Sycuan’s counterclaim. Courts can decline to exercise
    supplemental jurisdiction for compelling reasons, 28 U.S.C.
    10       UNITE HERE LOCAL 30 V. SYCUAN BAND
    § 1367(c)(4), in line with the principles of economy,
    convenience, fairness, and comity. See Arroyo v. Rosas,
    
    19 F.4th 1202
    , 1205 (9th Cir. 2021). The district court in
    this case declined supplemental jurisdiction here because
    adjudicating the counterclaim in federal court “would
    interfere with the arbitrator’s authority.” Citing Buckeye
    Check Cashing, Inc. v. Cardegna, 
    546 U.S. 440
    , 446 (2006),
    the district court concluded that the primary issue in the
    counterclaim was the contract’s validity, which should be
    considered by the arbitrator, not the court. Because the
    district court was correct that the arbitrator should decide
    issues of contract validity, as discussed below, and the
    counterclaim rests on an issue of contract validity, the
    district court’s declining to exercise supplemental
    jurisdiction served economy, convenience, and fairness. The
    district court did not abuse its discretion in declining to
    exercise supplemental jurisdiction.
    The State of California (State), in its amicus brief, also
    agrees that the district court appropriately declined to
    exercise supplemental jurisdiction because Sycuan failed to
    follow the Compact’s dispute resolution process. The State
    says that, according to the terms of the Compact, Sycuan was
    required to give California notice and then attempt to resolve
    the issue through the Compact’s dispute resolution process
    before filing the counterclaim, which it did not. The State
    also takes issue with Sycuan’s litigating Compact
    interpretation in a case where the State is not a party and
    argues that it must be a party to a suit seeking to invalidate
    any material term to the Compact. We agree with the State
    and conclude that its arguments were also compelling
    reasons for the district court not to exercise supplemental
    jurisdiction.
    UNITE HERE LOCAL 30 V. SYCUAN BAND                11
    In the alternative, Sycuan argues that the district court
    had original, federal question jurisdiction over its
    counterclaim. Federal question jurisdiction covers cases
    “arising under the Constitution, laws, or treaties of the
    United States.” 
    28 U.S.C. § 1331
    . “A case ‘arises under’
    federal law either where federal law creates the cause of
    action or ‘where the vindication of a right under state law
    necessarily turn[s] on some construction of federal law.’”
    Republican Party of Guam v. Gutierrez, 
    277 F.3d 1086
    ,
    1088–89 (9th Cir. 2002) (alteration in original) (citing
    Franchise Tax Bd. of Cal. v. Constr. Laborers Vacation Tr.
    for S. Cal., 
    463 U.S. 1
    , 8–9 (1983)). Sycuan argues its
    counterclaim arises under federal law because its declaratory
    judgment claim concerns the preemptive effect of a federal
    statute, the NLRA.
    Sycuan is incorrect; the district court did not have
    original jurisdiction over the counterclaim. The Declaratory
    Judgment Act is a procedural device only and requires a
    separate independent basis for jurisdiction. 
    28 U.S.C. § 2201
    (a); Skelly Oil Co. v. Phillips Petroleum Co., 
    339 U.S. 667
    , 671 (1950). Sycuan contends there is an independent
    basis for jurisdiction because the claim for a declaratory
    judgment arises out of a controversy about the application of
    the NLRA. However, under the well-pleaded complaint rule
    the federal question must be present on the face of a properly
    pleaded complaint and a “defense is not part of a [claimant]’s
    properly pleaded statement of his or her claim.” Rivet v.
    Regions Bank of La., 
    522 U.S. 470
    , 475 (1998). For
    declaratory judgments, “courts apply the well-pleaded
    complaint rule to the impending or threatened action, rather
    than the complaint seeking declaratory relief.”
    Stillaguamish Tribe of Indians v. Washington, 
    913 F.3d 1116
    , 1118 (9th Cir. 2019); see also Alton Box Bd. Co. v.
    Esprit de Corp., 
    682 F.2d 1267
    , 1274 (9th Cir. 1982). Here,
    12       UNITE HERE LOCAL 30 V. SYCUAN BAND
    that impending or threatened action is Unite Here’s claim for
    an order compelling arbitration. Although styled as a
    counterclaim for declaratory relief, Sycuan raises
    preemption as a defense to Unite Here’s claim. Under these
    circumstances, federal question jurisdiction cannot arise
    from such a defense.
    Further, the subject matter jurisdiction for Unite Here’s
    claim to compel arbitration rests on Section 301(a) of the
    Labor Management Relations Act, which gives subject
    matter jurisdiction to federal courts “for violation[s] of
    contracts between an employer and a labor organization.”
    
    29 U.S.C. § 185
    (a). There is jurisdiction over the claim for
    an order compelling arbitration because Unite Here alleges
    that Sycuan (the employer) violated a contract with Unite
    Here (a labor organization). But Section 301 cannot give
    original jurisdiction over the counterclaim challenging the
    TLRO’s validity because the challenge is to the agreement
    between Sycuan and the State of California, not a contract
    between an employer and a labor organization. There is no
    federal question jurisdiction for the declaratory relief
    counterclaim.
    III.   Formation of the Contract between Unite Here
    and Sycuan
    Sycuan contends that the district court cannot compel
    arbitration because there was no agreement between the
    parties to arbitrate. This is a question of contract formation
    and courts generally decide whether the parties formed a
    contract before compelling arbitration. See Granite Rock
    Co. v. Int’l Bhd. of Teamsters, 
    561 U.S. 287
    , 296 (2010).
    The parties do not dispute the material facts about the
    formation of the contract. As part of the Compact with
    California, Sycuan agreed to adopt and maintain the TLRO.
    UNITE HERE LOCAL 30 V. SYCUAN BAND                13
    In the TLRO, Sycuan promised California that if any union
    made certain promises contained in Section 7(b) of the
    TLRO to the Tribe, Sycuan would automatically enter into a
    bilateral contract with that union adopting the TLRO’s
    terms. Unite Here sent Sycuan a letter in November 2019,
    notifying the Tribe of its intent to organize and promising to
    comply with Section 7(b) of the TLRO. According to the
    promises Sycuan made to California, upon the receipt of this
    letter, a contract was immediately formed between Unite
    Here and Sycuan.
    Normally, “an ordinance . . . does not amount to an offer
    since it merely evidences the municipal corporation’s intent
    to do something in the future, but does not thereby make a
    promise that it shall be done.” 1 Williston on Contracts § 4:9
    (4th ed.). But if the ordinance is thereby communicated to
    another, “in such a way as to lead that other to believe that
    no further assent by the communicator is necessary, it may
    become an offer.” Id. Here, when Sycuan promised
    California that it would adopt and maintain the TLRO,
    Sycuan communicated to the union that no further assent
    was necessary. The TLRO is essentially an open-ended offer
    to any union to enter into a bilateral contract. When Unite
    Here sent the November 2019 letter and made promises to
    Sycuan, Unite Here accepted Sycuan’s offer.                As
    consideration for the contract, Unite Here made the promises
    contained in Section 7(b)—i.e., promises not to disparage
    the Tribe, attempt to influence the outcome of tribal
    elections, engage in economic disruption at the casino or
    strike-related picketing on tribal lands. When Sycuan
    received the November 2019 letter, an enforceable contract
    was formed.
    Sycuan claims that it never formed a contract with Unite
    Here because the TLRO is an unenforceable agreement to
    14        UNITE HERE LOCAL 30 V. SYCUAN BAND
    agree because the TLRO’s terms are not sufficiently definite.
    However, the terms of the contract were definitively
    established in the TLRO without any further negotiation
    between the union and the Tribe. Section 7(d) leaves little
    ambiguity. By its terms, any union’s Section 7(b) promises
    constitute an offer to accept all of the TLRO’s terms as a
    bilateral contract and Sycuan was bound to accept this offer.
    The terms were definite, there was nothing left to negotiate,
    and a contract was formed.
    IV.    Validity of the Contract between Unite Here and
    Sycuan
    Sycuan argues that the district court erred because its
    answer and counterclaim raise a valid affirmative defense of
    preemption. Sycuan contends that if the NLRA preempts the
    TLRO, there is no enforceable promise to arbitrate. Sycuan
    is mistaken.
    A defense that a law invalidates a contract with an
    arbitration provision is an issue for the arbitrator to decide.

    Court distinguished between a “challenge[] specifically [to]
    the validity of the agreement to arbitrate” and a “challenge[]
    [to] the contract as a whole, either on a ground that directly
    affects the entire agreement (e.g., the agreement was
    fraudulently induced), or on the ground that the illegality of
    one of the contract’s provisions renders the whole contract
    invalid.”

    . A court should decide only challenges
    to “the arbitration clause itself.”

    UNITE HERE LOCAL 30 V. SYCUAN BAND                 15
    Sycuan’s preemption argument is a challenge to the
    contract as a whole, not the arbitration clause. Sycuan says,
    “the Complaint is barred because the purported Tribal Labor
    Relations Ordinance, including any arbitration provisions
    contained therein, are preempted by the National Labor
    Relations Act, 
    29 U.S.C. § 151
    , et seq., and, therefore, is
    unenforceable where such provisions conflict with the
    NLRA.” Sycuan does not argue that the arbitration clause
    itself is invalid. Rather, Sycuan challenges the contract as a
    whole and so the preemption argument is for the arbitrator
    to decide. See Buckeye Check Cashing, 
    546 U.S. at
    445–46.
    Sycuan also argues that, if a contact does exist, the issue
    of NLRA preemption is outside the scope of the arbitration
    provisions of the TLRO. We can decide this issue because
    generally “courts will decide which issues are arbitrable.”
    Oracle Am., Inc. v. Myriad Grp. A.G., 
    724 F.3d 1069
    , 1072
    (9th Cir. 2013). The TLRO states that “[a]ll issues shall be
    resolved exclusively through the binding dispute resolution
    mechanisms herein.” Sycuan argues that “all issues” means
    all issues arising under the TLRO, and the TLRO does not
    mention the NLRA, preemption, or conflicts of law.
    Preemption is not excluded from the arbitration agreement.
    The arbitration agreement does not, and need not, cover only
    specifically identified disputes, Buckeye Check Cashing,
    Inc., 
    546 U.S. at
    443–44, and federal courts apply a
    presumption in favor of arbitrability, United Steelworkers of
    Am. v. Warrior & Gulf Nav. Co., 
    363 U.S. 574
    , 582–83
    (1960). The arbitration clause here is broad and covers “[a]ll
    issues” under the contract. Preemption as a defense to an
    alleged breach is an issue covered by the contract.
    Sycuan also argues that arbitrating NLRA preemption
    infringes on its sovereign immunity, which it claims it has
    not waived. “[A] waiver of [tribal] sovereign immunity
    16       UNITE HERE LOCAL 30 V. SYCUAN BAND
    ‘cannot be implied but must be unequivocally expressed.’”
    Santa Clara Pueblo v. Martinez, 
    436 U.S. 49
    , 58 (1978)
    (quoting United States v. Testan, 
    424 U.S. 392
    , 399 (1976)).
    Sycuan admits that it waived immunity for disputes “arising
    under” the TLRO. Sycuan denies, however, waiving
    sovereign immunity “with respect to the issue of NLRA
    preemption” because such a waiver was not clear and
    unequivocal. Sycuan also contends that NLRA preemption
    is a threshold issue that the district court should consider
    before sending the underlying claims to arbitration because
    if the NLRA preempts the TLRO then the waiver of
    sovereign immunity may also be preempted and arbitrating
    sovereign immunity is contrary to the principles of sovereign
    immunity.
    Here, there was an express waiver of tribal sovereign
    immunity as Sycuan agreed in Section 13(e) of the
    Compact’s TLRO to waive its immunity from suit for the
    purpose of compelling arbitration. Further, when a tribe
    agrees to judicial enforcement of an arbitration agreement it
    waives its immunity concerning that agreement. See C & L
    Enters. v. Citizen Band Potawatomi Indian Tribe of Okla.,
    
    532 U.S. 411
    , 418–20 (2001). Sycuan cites no law
    supporting its argument that the arbitration agreement must
    expressly list all issues to which the Tribe waives sovereign
    immunity. There is no sovereign immunity to arbitration
    because a party is only obligated to arbitrate when that party
    agreed to arbitrate, as Sycuan did here.
    Because the validity of the contract and the issue of
    preemption are for the arbitrator to decide, we do not
    examine the arguments or express a view on them here.

    motion for judgment on the pleadings and motion to dismiss
    Sycuan’s counterclaim.
