    Solomon v. St. Joseph Hosp.
    United States Court of Appeals
    for the Second Circuit
    August Term 2021
    Submitted: June 15, 2022
    Decided: March 7, 2023
    No. 21-2729
    ZACHARY SOLOMON,
    Plaintiff-Appellee,
    v.
    ST. JOSEPH HOSPITAL,
    CATHOLIC HEALTH SYSTEM OF LONG ISLAND, INC.,
    Defendants-Appellants.
    On Appeal from the United States District Court
    for the Eastern District of New York
    Before: LIVINGSTON, Chief Judge, and CABRANES and PARK, Circuit
    Judges.
    Plaintiff Zachary Solomon sued Defendants St. Joseph Hospital
    and Catholic Health System of Long Island, Inc. for injuries he
    sustained at St. Joseph Hospital, where he was admitted in March
    2020 with COVID-19. Solomon brought claims for malpractice,
    negligence, and gross negligence in New York state court.
    Defendants removed the case to the United States District Court for
    the Eastern District of New York and moved to dismiss for lack of
    subject-matter jurisdiction. Defendants asserted state and federal
    immunities under the Emergency or Disaster Treatment Protection
    Act (“EDTPA”), 
    N.Y. Pub. Health Law §§ 3080-3082
    , and the Public
    Readiness and Emergency Preparedness Act (“PREP Act”), 42 U.S.C.
    §§ 247d-6d, 247d-6e. The district court (Block, J.) denied Defendants’
    motion to dismiss.
    We conclude that removal to federal court was improper
    because the district court lacked jurisdiction to hear the case. First,
    Solomon’s state-law claims are not completely preempted by the
    PREP Act. Second, there is no jurisdiction under the federal-officer
    removal statute because Defendants did not “act under” a federal
    officer. Finally, Solomon’s claims do not “arise under” federal law.
    We thus VACATE the district court’s order and REMAND with
    directions to remand the case to state court.

    PARK, Circuit Judge:
    Plaintiff Zachary Solomon sued Defendants St. Joseph Hospital
    and Catholic Health System of Long Island, Inc. for injuries he
    sustained at St. Joseph Hospital, where he was admitted in March
    2020 with COVID-19.       Solomon brought claims for malpractice,
    negligence, and gross negligence in New York state court.
    Defendants removed the case to the United States District Court for
    the Eastern District of New York and moved to dismiss for lack of
    subject-matter jurisdiction. Defendants asserted state and federal
    immunities under the Emergency or Disaster Treatment Protection
    Act (“EDTPA”), 
    N.Y. Pub. Health Law §§ 3080-3082
    , and the Public
    Readiness and Emergency Preparedness Act (“PREP Act”), 42 U.S.C.
    §§ 247d-6d, 247d-6e. The district court (Block, J.) denied Defendants’
    motion to dismiss.
    We conclude that removal to federal court was improper
    because the district court lacked jurisdiction to hear the case. First,
    Solomon’s state-law claims are not completely preempted by the
    PREP Act. Second, there is no jurisdiction under the federal-officer
    3
    removal statute because Defendants did not “act under” a federal
    officer. Finally, Solomon’s claims do not “arise under” federal law.
    We thus vacate the district court’s order and remand with directions
    to remand the case to state court.
    I. BACKGROUND
    A.    Statutory Scheme
    The PREP Act provides broad immunity “from suit and
    liability under Federal and state law with respect to all claims for loss
    caused by, arising out of, relating to, or resulting from the
    administration to or the use by an individual of a covered
    countermeasure” during a public-health emergency.             42 U.S.C.
    § 247d-6d(a)(1). The PREP Act gives the Secretary of the Department
    of Health and Human Services (“HHS Secretary”) authority to
    publish a declaration that (1) announces a disease or health condition
    is a public emergency and (2) defines appropriate covered
    countermeasures. Id. § 247d-6d(b)(1).
    Effective February 4, 2020, the HHS Secretary declared
    “COVID-19 . . . a public health emergency” and defined “covered
    countermeasures” as any “antiviral, drug, biologic, diagnostic,
    device, or vaccine used to treat, diagnose, cure, prevent, or mitigate
    COVID-19.”         Declaration Under the PREP Act for Medical
    Countermeasures Against COVID-19, 
    85 Fed. Reg. 15198
    , 15198-01
    (Mar. 17, 2020).
    The PREP Act contains one exception to immunity for claims
    “for death or serious physical injury proximately caused by willful
    misconduct.”       42 U.S.C. § 247d-6d(d)(1).   Willful misconduct is
    defined as “an act or omission that is taken (i) intentionally to achieve
    4
    a wrongful purpose; (ii) knowingly without legal or factual
    justification; and (iii) in disregard of a known or obvious risk that is
    so great as to make it highly probable that the harm will outweigh the
    benefit.”   Id. § 247d-6d(c)(1)(A).       The PREP Act grants exclusive
    federal jurisdiction over such claims to the United States District
    Court for the District of Columbia. Id. § 247d-6d(e)(1). For all other
    claims, the PREP Act establishes a Covered Countermeasure Process
    Fund to compensate “eligible individuals for covered injuries directly
    caused by the administration or use of a covered countermeasure
    pursuant to such declaration.” Id. § 247d-6e(a).
    B.    Procedural History
    Solomon was admitted to St. Joseph Hospital on March 23,
    2020, after testing positive for COVID-19 and exhibiting severe
    shortness of breath and a high fever. Soon after his admission,
    Solomon was intubated for ten days, during which time he developed
    severe pressure sores.
    Solomon sued St. Joseph Hospital and its operator, Catholic
    Health System of Long Island, Inc., in the Supreme Court of the State
    of New York for the County of Nassau. Solomon alleged state-law
    causes of action for malpractice, negligence, and gross negligence.
    Defendants removed the case to the United States District Court for
    the Eastern District of New York. Defendants argued that federal
    jurisdiction was proper because: (1) the PREP Act preempted state
    law, (2) the federal-officer removal statute permitted removal, and
    (3) the case implicated substantial federal issues. Solomon did not
    object to removal.
    Defendants then moved to dismiss under Rule 12(b)(1) and
    12(b)(6) of the Federal Rules of Civil Procedure, arguing that they
    5
    were immune from liability under both state and federal law based
    on the EDTPA and PREP Act. As to immunity under the PREP Act,
    Defendants argued that Solomon developed pressure sores because
    he could not be rotated after being placed on a ventilator to treat
    COVID-19 so his injuries are “inextricably intertwined with the use of
    a covered countermeasure.” Appellants’ Br. at 26. Defendants also
    argued that they were immune from liability under the EDTPA
    because, at the time of Solomon’s hospitalization, the EDTPA
    immunized health-care facilities from liability from many claims
    resulting from health-care decisions made “in response to or as a
    result of” COVID-19. 
    N.Y. Pub. Health Law § 3082
    (1)(b). Solomon
    opposed Defendants’ motion but did not address whether federal
    jurisdiction was proper.
    The district court denied Defendants’ motion to dismiss. First,
    the district court found that Solomon’s claims did not fall within the
    immunity provision of the PREP Act.          The court reasoned that
    “Solomon’s claims derive from a common type of hospital-acquired
    injury that results from not being rotated while stationary.” App’x at
    A-72. The district court concluded that Defendants were not entitled
    to PREP Act immunity merely because Solomon was also being
    “treated for COVID-19 with a ventilator during the period that he
    acquired” his injury.      
    Id.
       Second, the district court found that
    Defendants were not entitled to EDTPA immunity because they failed
    to show “that Solomon’s pressure injury directly resulted from
    decisions or activities in response to or as a result of the COVID-19
    outbreak.” 
    Id.
     at A-76. In addition, the district court found that
    Solomon sufficiently pleaded a claim for gross negligence, which is a
    type of claim exempt from EDTPA immunity. 
    N.Y. Pub. Health Law § 3082
    (2).
    6
    Defendants timely appealed. They argue that an immediate
    appeal is proper under the collateral-order doctrine because the
    district court denied them immunity from suit.
    Solomon did not object to removal below or offer any
    opposition to Defendants’ arguments on appeal.          We appointed
    amicus curiae to brief whether we have appellate jurisdiction over the
    district court’s order denying Defendants’ motion to dismiss and
    whether the district court had subject-matter jurisdiction to hear the
    case below. On January 19, 2023, amicus provided briefing arguing
    that this Court has appellate jurisdiction to review whether federal
    jurisdiction was proper and that the district court lacked subject-
    matter jurisdiction over the case below. 1
    II. DISCUSSION
    Defendants argue that there is federal jurisdiction over this case
    for three reasons. First, the PREP Act completely preempts Solomon’s
    state-law claims.    Second, Defendants were subject to federal
    regulations, bringing them under the federal-officer removal statute.
    Finally, Solomon’s claims arise under federal law.
    We have appellate jurisdiction to determine whether the
    district court had jurisdiction below. See Arizonans for Off. Eng. v.
    Arizona, 
    520 U.S. 43
    , 73 (1997) (“When the lower federal court lacks
    jurisdiction, we have jurisdiction on appeal, not of the merits but
    merely for the purpose of correcting the error of the lower court in
    entertaining the suit.” (cleaned up)); In re Methyl Tertiary Butyl Ether
    Prods. Liab. Litig., 
    488 F.3d 112
    , 121 (2d Cir. 2007) (“We conclude that
    1 We thank Hoover & Durland LLP for serving as court-appointed
    amicus curiae.
    7
    review of [whether we have subject-matter jurisdiction] is required
    pursuant to our independent obligation to satisfy ourselves of the
    jurisdiction of this court and the court below.”). As a result, we need
    not decide whether Defendants’ interlocutory appeal is proper under
    the collateral-order doctrine. Solomon did not object to removal, but
    “[t]his court may sua sponte delve into the issue of whether there is a
    factual basis to support subject-matter jurisdiction.”         Platinum-
    Montaur Life Scis., LLC v. Navidea Biopharmaceuticals, Inc., 
    943 F.3d 613
    ,
    616 (2d Cir. 2019) (cleaned up). We review questions of subject-matter
    jurisdiction de novo. 
    Id.
    A.    Complete Preemption
    Defendants first argue that federal jurisdiction is proper under
    the doctrine of complete preemption. We disagree. The PREP Act
    permits only one federal cause of action (for willful misconduct), and
    Solomon’s claims do not fall within its narrow scope.
    1.     Legal Principles
    Under 
    28 U.S.C. § 1441
    , a state-court defendant may remove a
    civil action to federal court if the action could have been filed in
    federal court in the first place. When, as here, there is no “diversity
    of citizenship, federal-question jurisdiction is required.” Caterpillar
    Inc. v. Williams, 
    482 U.S. 386
    , 392 (1987). “The presence or absence of
    federal-question jurisdiction is governed by the ‘well-pleaded
    complaint rule,’ which provides that federal jurisdiction exists only
    when a federal question is presented on the face of the plaintiff’s
    properly pleaded complaint.” 
    Id.
     “[A] case may not be removed to
    8
    federal court on the basis of a federal defense, including the defense
    of pre-emption.” 
    Id. at 393
    .
    “The complete preemption doctrine is an exception to the well-
    pleaded complaint rule.” Whitehurst v. 1199SEIU United Healthcare
    Workers E., 
    928 F.3d 201
    , 206 (2d Cir. 2019). Complete preemption
    occurs when a federal statute preempts and replaces all state-law
    causes of action so “a claim which comes within the scope of that
    [federal] cause of action, even if pleaded in terms of state law, is in
    reality based on federal law.” In re WTC Disaster Site, 
    414 F.3d 352
    ,
    372 (2d Cir. 2005). In those cases, “the pre-emptive force of a statute
    is so ‘extraordinary’ that it ‘converts an ordinary state common-law
    complaint into one stating a federal claim for purposes of the well-
    pleaded complaint rule.’” Caterpillar, 
    482 U.S. at 393
     (quoting Metro.
    Life Ins. Co. v. Taylor, 
    481 U.S. 58
    , 65 (1987)); accord Sullivan v. Am.
    Airlines, Inc., 
    424 F.3d 267
    , 272 (2d Cir. 2005). “When a plaintiff raises
    such a completely preempted state-law claim in his complaint, a court
    is obligated to construe the complaint as raising a federal claim and
    therefore ‘arising under’ federal law.” Sullivan, 424 F.3d at 272. 2
    2 Complete preemption is rare. The Supreme Court has identified
    only three instances of complete preemption: Section 301 of the Labor
    Management Relations Act, see Avco Corp. v. Aero Lodge No. 735, 
    390 U.S. 557
    , 558–62 (1968); Section 502(a)(1)(B) of the Employee Retirement Income
    Security Act (“ERISA”), see Metro. Life Ins. Co., 
    481 U.S. at
    65–66; and
    Sections 85 and 86 of the National Bank Act, see Beneficial Nat'l Bank v.
    Anderson, 
    539 U.S. 1
    , 7–11, (2003). We have identified two other instances:
    Section 408 of the Air Transportation Safety and System Stabilization Act,
    see In re WTC Disaster Site, 414 F.3d at 375–76; and Section 301 of the
    Copyright Act, see Briarpatch Ltd. v. Phoenix Pictures, Inc., 
    373 F.3d 296
    , 305
    (2d Cir. 2004).
    9
    2.     Application
    Solomon’s state-law claims for malpractice, negligence, and
    gross negligence do not fall within the scope of the PREP Act’s
    exclusive federal cause of action for willful misconduct. As a result,
    his claims cannot be removed to federal court under the complete
    preemption doctrine.
    To establish complete preemption, Defendants must first show
    that the PREP Act “preempts state law and substitutes a federal
    remedy for that law, thereby creating an exclusive federal cause of
    action.” Briarpatch, 
    373 F.3d at 305
    . Once this is established, the
    question becomes whether Solomon’s state-law claims are “within the
    scope” of the federal cause of action. Aetna Health Inc. v. Davila, 
    542 U.S. 200
    , 209 (2004); see also Beneficial Nat'l Bank v. Anderson, 
    539 U.S. 1
    , 8 (2003) (“When the federal statute completely pre-empts the state-
    law cause of action, a claim which comes within the scope of that cause of
    action, even if pleaded in terms of state law, is in reality based on
    federal law.” (emphasis added)).        If so, the state-law claims are
    completely preempted.
    The PREP Act’s cause of action for willful misconduct is
    unambiguously “an exclusive Federal cause of action.” 42 U.S.C.
    § 247d-6d(d)(1). And like other complete preemption statutes, the
    PREP Act not only provides an “exclusive cause of action for the claim
    asserted,” but also “set[s] forth procedures and remedies governing
    that cause of action.” Beneficial Nat’l Bank, 
    539 U.S. at 8
    ; see 42 U.S.C.
    § 247d-6d(e). The PREP Act further provides a specific preemption
    provision applicable to certain state laws that conflict with the Act.
    See 42 U.S.C. § 247d-6d(b)(8).
    10
    Solomon’s state-law claims are not completely preempted.
    First, claims for medical malpractice, negligence, and gross
    negligence are plainly not “within the scope” of willful misconduct.
    Negligence and gross negligence do not rise to the level of willful
    misconduct, which the PREP Act defines as “a standard for liability
    that is more stringent than a standard of negligence in any form.” 42
    U.S.C. § 247d-6d(c)(1)(B) (emphasis added). 3 Similarly, under New
    York law, medical malpractice requires only a deviation from the
    community standards of practice that proximately caused the injuries.
    See Dixon v. Chang, 
    163 A.D.3d 525
    , 526 (2d Dep’t 2018). This standard
    is more relaxed than the showing required for willful misconduct,
    which is an act or omission taken (i) “intentionally to achieve a
    wrongful purpose;” (ii) “knowingly without legal or factual
    justification;” and (iii) “in disregard of a known or obvious risk that
    is so great as to make it highly probable that the harm will outweigh
    the benefit.” 42 U.S.C. § 247d-6d(c)(1)(A).
    Second, the PREP Act does not create any other exclusive
    federal cause of action that might encompass Solomon’s state-law
    claims.    Instead, the PREP Act principally creates an immunity
    scheme. And immunity has no bearing on complete preemption,
    which is a jurisdictional doctrine, not a preemption-defense doctrine. 4
    3 Although the Supreme Court has instructed that our preemption
    inquiry should not focus on the “particular label affixed to” a particular
    claim, Davila, 
    542 U.S. at 214
    , this statutory language specifies that no form
    of negligence can constitute willful misconduct.
    4 State courts addressing immunity defenses under the PREP Act are
    required to answer only whether the plaintiff’s claims fall within the PREP
    Act’s immunity provision. See 42 U.S.C. § 247d-6d(a)(1). If the answer is
    no, as the district court found, there is no federal law left to apply and the
    case can proceed under state law. If the answer is yes, the immunity ends
    11
    See Avco Corp., 
    390 U.S. at 561
     (“[T]he breadth or narrowness of the
    relief which may be granted under federal law . . . is a distinct
    question from whether the court has jurisdiction over the parties and
    the subject matter.”); see also Davila, 
    542 U.S. at
    215–16 (holding that
    the remedies available under ERISA were not an appropriate
    consideration for the complete preemption analysis). The PREP Act
    thus does not completely preempt Solomon’s state-law claims for
    malpractice, negligence, or gross negligence. 5
    This conclusion is in line with every other Court of Appeals that
    has addressed the issue to date. See Hudak Est. of Koballa v. Elmcroft of
    Sagamore Hills, 
    58 F.4th 845
    , 854–57 (6th Cir. 2023); Martin v. Petersen
    Health Operations, LLC, 
    37 F.4th 1210
    , 1213–14 (7th Cir. 2022); Mitchell
    v. Advanced HCS, L.L.C., 
    28 F.4th 580
    , 584–88 (5th Cir. 2022); Salanda v.
    Glenhaven Healthcare LLC, 
    27 F.4th 679
    , 686–88 (9th Cir. 2022); Maglioli
    the case, and litigants may either file a claim for willful misconduct in the
    United States District Court for the District of Columbia, 
    id.
     § 247d-6d(e)(1),
    or seek relief from the compensation fund, id. § 247d-6e(a). The PREP Act’s
    immunity provision thus governs whether state or federal law applies; it
    does not—contrary to Defendants’ claims—independently confer federal
    jurisdiction.
    5 The PREP Act also creates a compensation fund for certain claims,
    which can be sought through an administrative process. See 42 U.S.C.
    § 247d-6e(a). But the compensation fund is not itself an exclusive federal
    cause of action because it does not create a cause of action that can be
    litigated in federal court. Nothing about the compensation fund indicates
    that Congress intended to grant exclusive federal jurisdiction over claims
    subject to this administrative process. See Mitchell v. Advanced HCS, L.L.C.,
    
    28 F.4th 580
    , 587 (5th Cir. 2022). “[N]either the Supreme Court nor any
    circuit court has extended complete preemption to a statute because it
    created a compensation fund.” Maglioli v. All. HC Holdings LLC, 
    16 F.4th 393
    , 412 (3d Cir. 2021).
    12
    v. All. HC Holdings LLC, 
    16 F.4th 393
    , 406–13 (3d Cir. 2021). It is also
    consistent with the decisions of district courts within this Circuit. See
    Aponte v. Our Lady of Consolation Nursing & Rehab. Care Ctr., No. 22-
    cv-0018, 
    2022 WL 17851799
    , at *7 (E.D.N.Y. Dec. 22, 2022) (collecting
    cases).
    Defendants nonetheless argue that permitting plaintiffs to
    “proceed in state court simply by declining to allege willfulness in
    their complaints” would “frustrate the purpose of the PREP Act.”
    Appellants’ Reply Br. at 10, 12. We disagree. The immunity provision
    of the PREP Act would still apply to any such artfully pled
    complaints, whether those complaints are brought in state or federal
    court.     Defendants are correct that the PREP Act demonstrates
    Congress’s intent to “eliminate all other causes of action” for
    immunized claims, 
    id. at 14
    , but nothing in the PREP Act suggests that
    Congress was attempting also to eliminate state-law causes of action
    for non-immunized claims.
    It is true that the HHS Secretary and Office of General Counsel
    view the PREP Act as a complete preemption statute.                See Fifth
    Amendment to Declaration Under the PREP Act for Medical
    Countermeasures Against COVID-19, 
    86 Fed. Reg. 7872
    -02, 7874 (Feb.
    2, 2021) (“The plain language of the PREP Act makes clear that there
    is complete preemption of state law.”); U.S. Dep’t Health & Hum.
    Servs., Advisory Opinion 20-01 on the PREP Act Scope of Preemption
    Provision (Jan. 8, 2021).       But we do not defer to the agency’s
    interpretation of an unambiguous statutory provision concerning the
    scope of federal jurisdiction. See, e.g., Bechtel v. Competitive Techs., Inc.,
    
    448 F.3d 469
    , 478 (2d Cir. 2006) (Leval, J., concurring); see also Smith v.
    Berryhill, 
    139 S. Ct. 1765
    , 1778 (2019) (“[A]lthough agency
    13
    determinations within the scope of delegated authority are entitled to
    deference, it is fundamental ‘that an agency may not bootstrap itself
    into an area in which it has no jurisdiction.’” (quoting Adams Fruit Co.
    v. Barrett, 
    494 U.S. 638
    , 650 (1990)).
    B.    Federal-Officer Removal
    1.     Legal Principles
    Under the federal-officer removal statute, an action against
    certain federal officers commenced in state court may be removed to
    federal court. See 
    28 U.S.C. § 1442
    (a)(1). Private actors may invoke
    jurisdiction under § 1442 if they are (1) persons, including
    corporations, “who acted under a federal officer”; (2) “being sued for
    an act taken under color of [federal] office”; and (3) “raise[] a
    colorable federal defense.” Badilla v. Midwest Air Traffic Control Serv.,
    Inc., 
    8 F.4th 105
    , 120 (2d Cir. 2021) (cleaned up). Although the words
    “acting under” are broad, “broad language is not limitless.” Watson
    v. Philip Morris Cos., Inc., 
    551 U.S. 142
    , 147 (2007). “[T]he private
    person’s ‘acting under’ must involve an effort to assist, or to help carry
    out, the duties or tasks of the federal superior” and “does not include
    simply complying with the law.” 
    Id. at 152
    .
    2.     Application
    Defendants’ argument that they “act under” a federal officer
    for purposes of the PREP Act is meritless.
    First, Defendants do not “act under” a federal officer simply
    because they operate in a heavily regulated industry. A private
    company’s “compliance (or noncompliance) with federal laws, rules,
    and regulations does not by itself fall within the scope of the statutory
    phrase ‘acting under’ a federal ‘official.’ And that is so even if the
    14
    regulation is highly detailed and even if the private firm’s activities
    are highly supervised and monitored.”              Watson, 
    551 U.S. at 153
    .
    Defendants may be subject to federal regulations and guidance
    governing the care they provide (including in connection with
    COVID-19), but that does not mean that they “act under” a federal
    officer.
    Second, Defendants’ role during the COVID-19 pandemic has
    nothing to do with whether they were “acting under” a federal officer.
    As other courts of appeals have held, “[i]t cannot be that the federal
    government’s mere designation of an industry as important—or even
    critical—is sufficient to federalize an entity’s operations and confer
    federal jurisdiction.” Salanda, 27 F.4th at 685 (quoting Buljic v. Tyson
    Foods, Inc., 
    22 F.4th 730
    , 740 (8th Cir. 2021)).
    C.    “Arising Under” Jurisdiction
    1.    Legal Principles
    Under 
    28 U.S.C. § 1331
    , federal courts have subject-matter
    jurisdiction over “all civil actions arising under the Constitution,
    laws, or treaties of the United States.” “[E]ven where a claim finds its
    origins in state rather than federal law,” “arising under” jurisdiction
    still lies in “a special and small category of cases” in which the federal
    issue is: “(1) necessarily raised, (2) actually disputed, (3) substantial,
    and (4) capable of resolution in federal court without disrupting the
    federal-state balance approved by Congress.” Gunn v. Minton, 
    568 U.S. 251
    , 258 (2013) (cleaned up).           “Where all four of these
    requirements are met . . . [federal] jurisdiction is proper because there
    is a ‘serious federal interest in claiming the advantages thought to be
    inherent in a federal forum,’ which can be vindicated without
    disrupting Congress’s intended division of labor between state and
    15
    federal courts.” 
    Id.
     (quoting Grable & Sons Metal Prods., Inc. v. Darue
    Eng'g & Mfg., 
    545 U.S. 308
    , 313–14 (2005)).
    2.      Application
    Removal to federal court is not proper under federal “arising
    under”      jurisdiction   because    Solomon’s     complaint      does    not
    necessarily raise a federal issue.
    To determine whether an issue is “necessarily raised” we
    consider whether “a right or immunity created by the Constitution or
    laws of the United States is an element, and an essential one, of the
    plaintiff’s cause of action.” Tantaros v. Fox News Network, LLC, 
    12 F.4th 135
    , 141 (2d Cir. 2021) (cleaned up). Here, Solomon’s complaint raises
    claims under New York law and does not, on its face, raise questions
    of federal law. Although Defendants have sought to avail themselves
    of the immunity granted under the PREP Act, our “inquiry must be
    unaided by anything alleged in anticipation or avoidance of defenses
    which it is thought the defendant may interpose . . . even if the
    defense is anticipated in the plaintiff’s complaint, and even if both
    parties admit that the defense is the only question truly at issue in the
    case.” 
    Id.
     at 141–42 (cleaned up). Defendants’ argument thus fails at
    the first step. 6
    6 Defendants’ reliance on Arbaugh v. Y&H Corp., 
    546 U.S. 500
     (2006),
    is misplaced. The Supreme Court in Arbaugh noted that a plaintiff properly
    invokes federal jurisdiction under § 1331 when there is a “colorable claim”
    under federal law, but not a “wholly insubstantial and frivolous” federal
    claim that is “immaterial and made solely for the purpose of obtaining
    jurisdiction.” Id. at 513 n.10 (cleaned up). Arbaugh does not hold that
    federal courts have jurisdiction even when a plaintiff does not bring a federal
    claim merely because the court speculates that the plaintiff could have done
    so.
    16
    III. CONCLUSION
    Defendants have failed to show that federal jurisdiction is
    proper, so Solomon’s state-law claims must be litigated in state court.
    We thus vacate the district court’s order and remand with directions
    to remand this case to state court.
