OPINION
These consolidated appeals arise from two separate actions that involve California Shock Trauma Air Rescue (CALSTAR). Both actions turn on the same jurisdictional question: is the expectation of a federal defense, without more, sufficient to establish federal jurisdiction over a state-law claim? Despite CALSTAR’s arguments to the contrary, we reiterate that the well-pleaded complaint rule precludes the exercise of federal subject matter jurisdiction over purely state-law causes of action, like the one raised here.
I.
CALSTAR provides air-ambulance rescue services to employees injured in the course of their employment, and whose employers are either self-insured or have
In 2009, CALSTAR filed its actions in the Eastern District of California, alleging state-law claims of quantum meruit, unjust enrichment, and open book account. CALSTAR also sought a declaratory judgment that the state statute regulating air-ambulance rates is pre-empted by federal law. In the 1970s, the federal government adopted legislation — the Federal Aviation Act of 1958 (FAA), as amended by the Airline Deregulation Act of 1978, codified at 49 U.S.C. § 41713(b)(1) — to increase airline competition and lower air-fare prices. According to CALSTAR, the FAA preempts the workers’ compensation statute at issue.
The FAA preemption question is the sole basis on which CALSTAR attempts to have its actions adjudicated in federal court. Relying on Federal Rule of Civil Procedure 12(e)(1), the district court concluded that subject matter jurisdiction was lacking and dismissed CALSTAR’s claims. CALSTAR now appeals. We review the district court’s dismissal for lack of subject matter jurisdiction de novo, Kildare v. Saenz,
II.
Under 28 U.S.C. § 1331, federal courts have jurisdiction over those actions “arising under the Constitution, laws, or treaties of the United States.” While plaintiffs usually invoke section 1331 jurisdiction for violations of federal law, they also may invoke it over certain state-law claims. Grable & Sons Metal Prods., Inc. v. Darue Eng’g & Mfg.,
In determining whether a federal district court has “arising under” jurisdiction over a claim, we must keep in mind “the basic principle marking the boundaries of the federal question jurisdiction of the federal district courts”: the well-pleaded complaint rule. Metro. Life Ins. Co. v. Taylor,
We thus are required to consider whether CALSTAR’s complaints satisfy the well-pleaded complaint rule. CALSTAR is suing Employers under various state-law theories. CALSTAR anticipates that Employers will respond by asserting, as a defense, that they correctly paid CALSTAR pursuant to California’s air-ambulance rate regulation. In response to that defense, CALSTAR anticipates arguing that the state’s air-ambulance rate regulation is inapplicable because the FAA preempts the state regulation. It is evident that CALSTAR’s federal preemption argument is not necessary to its state-law claims — it is merely a potential response to a defense. Because CALSTAR’s preemption issue cannot satisfy the well-pleaded complaint rule, there is no basis for federal question jurisdiction.
Any doubt about our analysis is removed by Phillips Petroleum Co. v. Texaco, Inc.,
Ignoring Phillips Petroleum, CALSTAR invokes the Supreme Court’s decision in Grable and argues that a federal court may entertain any action if it involves “significant federal issues.”
Read in isolation, this statement arguably suggests that federal courts may exercise jurisdiction over any state-law claim that “implicate[s] significant federal issues.” In fact, this is the very interpretation that CALSTAR asks us to adopt. Nevertheless, contrary to CALSTAR’s suggestion, Grable did not implicitly overturn the well-pleaded complaint rule— which has long been a “basic principle marking the boundaries of the federal question jurisdiction of the federal district courts,” Metropolitan Life,
III.
The other potential basis for federal jurisdiction is CALSTAR’s claim for declaratory relief. Pursuant to that claim, CALSTAR seeks a declaration that the FAA preempts the now obsolete fee schedule for air ambulances. See Cal.Code Regs. tit. 8 § 9789.70.
“[T]he operation of the Declaratory Judgment Act is procedural only” and does not confer arising under jurisdiction. Skelly Oil Co. v. Phillips Petroleum Co.,
It is beyond dispute that federal courts have jurisdiction over suits to enjoin state officials interfering with federal rights. Ex parte Young,209 U.S. 123 , 160-62 [28 S.Ct. 441 ,52 L.Ed. 714 ] (1908). A plaintiff who seeks injunctive relief from state regulation, on the ground that such regulation is pre-empted by a federal statute which, by virtue of the Supremacy Clause of the Constitution, must prevail, thus presents a federal question which the federal courts have jurisdiction under 28 U.S.C. § 1331 to resolve.
Id. at 96 n. 14,
CALSTAR’s argument is a matter of first impression within our circuit and therefore we must address it. In Shaw, the Supreme Court predicated its jurisdictional holding on the fact that a state official was the defendant. Id. Relying on Ex parte Young, the Court held that there was arising under jurisdiction over an action against a state attorney general, acting in his official capacity, who allegedly violated federal law.
Furthermore, to the extent that CALSTAR contends that Shaw opened the door to its argument, it ignores Supreme Court precedent that keeps that door closed. If we ruled as CALSTAR suggests we do, we
At bottom, CALSTAR’s argument is nothing more than a “futile ... attempt to define a ‘cause of action’ without reference to ... context.” Gully,
To define broadly and in the abstract “a case arising under the Constitution or laws of the United States” has hazards of a kindred order.... [T]he courts have formulated the distinction between controversies that are basic and those that are collateral, between disputes that are necessary and those that are merely possible. We shall be lost in a maze if we put that compass by.
Id. at 117-18,
Our analysis is strengthened by the fact that those circuits to address the argument now raised by CALSTAR have unanimously rejected it. See Colonial Penn Grp., Inc. v. Colonial Deposit Co.,
IV.
Because there is no federal jurisdiction over any of CALSTAR’s claims, we affirm the district court’s dismissal for lack of jurisdiction. We therefore need not address the parties’ remaining arguments. We do, however, grant Employers’ motion to take judicial notice of CALSTAR’s state-law complaint.
Costs on appeal are awarded to Employers.
AFFIRMED.
