The central issues in this appeal concern federal jurisdiction and choice-of-law under
Erie Railroad Co. v. Tompkins,
*1314 I
The Indians claim that during their employment between 1948 and 1966 at uranium mines in the Navajo reservation leased and operated by appellees, Kerr-McGee Corp. and several other mining corporations (the companies), the miners were exposed to substantial amounts of radon radiation, causing lung cancer, other severe radiation-related injuries and, in some instances, death. Their second amended complaint alleged jurisdiction based upon diversity of citizenship and sought damages on theories of negligence, strict liability and intentional tort. Applying Arizona substantive law as required by
Erie,
the district court dismissed this complaint, “without prejudice,” for lack of subject matter jurisdiction, concluding that the sole remedy provided by Arizona law for the Indians’ alleged injuries is an administrative claim for workers’ compensation vested in the exclusive jurisdiction of the Industrial Commission of Arizona (the Commission).
Subsequently, the Indians filed a fourth amended complaint alleging that their claims fell within certain statutory exceptions to the Commission’s exclusive jurisdiction, and added an assertion of federal question jurisdiction under 28 U.S.C. § 1331, alleging that the case arises under the Constitution, the Navajo Treaty, 15 Stat. 667 (1868), and the Arizona Enabling Act, 36 Stat. 568, ch. 310, §§ 19-35 (1910). The district court dismissed this complaint but granted leave to file another amended complaint alleging the failure of the companies to comply with Arizona’s workers’ compensation statutory notice requirement, Ariz.Rev.Stat. § 23-906(D), (E) (Supp.1981).
II
Although the parties have not raised the issue, we must first determine whether we have jurisdiction over this appeal. “[Generally a mere dismissal of a complaint without expressly dismissing the action is not an appealable final order” under section 1291.
Mark v. Groff,
Ill
We next address the issue of federal question jurisdiction. The district courts are vested with jurisdiction to hear all cases and controversies, regardless of amount in controversy, arising under the Constitution and laws of the United States. 28 U.S.C. § 1331. A case does not arise under federal law within the meaning of section 1331 if the complaint merely anticipates or replies to a probable defense which would be based on federal law.
See, e.g., Phillips Petroleum Co. v. Texaco Inc.,
IV
The parties and the district court have mistakenly approached the next issue in this case — the choice of applicable law under
Erie
— as one of subject matter jurisdiction. See
id.
at 1323. Unlike their assertion of federal question jurisdiction, however, it is clear that the Indians properly invoked the district court’s diversity jurisdiction. Each plaintiff in this case is a citizen of a different state from each defendant, 28 U.S.C. § 1332(a)(1), (c);
Munoz v. Small Business Admin.,
The district judge apparently concluded that because Arizona law would deprive an Arizona court of jurisdiction in a like case filed in state court, the federal court lacked diversity jurisdiction. Here, he erred. The question is whether the Indians’ complaint stated a claim for relief under Arizona law pursuant to
Erie,
rather than whether the district court lacked subject matter jurisdiction.
See Black v. Payne,
Indeed, the
Erie
doctrine rests upon the premise that the jurisdiction of the federal diversity court is satisfied, and addresses only the question whether federal or state law provides the substantive rules of decision in the case.
See Erie, supra,
The companies argue that the Arizona workers’ compensation statutes, by vesting exclusive jurisdiction in the Arizona Industrial Commission, deprive the district court of diversity jurisdiction. Kerr-McGee Corp. does so without a single citation to federal authority. The other companies rely principally on
Woods v. Interstate Realty Co.,
The York case was premised on the theory that a right which local law creates but which it does not supply with a remedy is no right at all for purposes of enforcement in a federal court in a diversity case: that where in such cases one is barred from recovery in the state court, he should likewise be barred in the federal court.
It is evident from this language, and because the district court acted on the merits by granting summary judgment for the defendant, that the Supreme Court’s holding is that the state “door-closing” statute prevented the diversity plaintiff, as a matter of law, from stating a claim upon which relief could be granted. The state rule was “intended to be bound up with the definition of the rights and obligations of the parties,”
Byrd v. Blue Ridge Rural Elec. Coop., Inc.,
Some language in two of our older decisions seems to support the district court.
See Hot Oil Serv., Inc. v. Hall,
[T]he exclusive tribal jurisdiction may be altered by express declaration of Congress. Littell urges that the diversity statute is just such a declaration.... [But] even after granting that Littell’s suit falls within the letter of the diversity statute, we believe that the basic principle of diversity jurisdiction requires reference of the suit to the Navajo Tribal Courts.
V
We must, however, affirm the district court’s order dismissing the Indians’ diversity complaint if the complaint and action should have been dismissed, notwithstanding that the district court incorrectly dismissed for lack of subject matter jurisdiction.
See, e.g., Edinburgh Assurance Co.
v.
R. L. Burns Corp.,
The district court construed Arizona law as vesting exclusive jurisdiction over the Indians’ damage claims in the Commission,
Whether these provisions of Arizona workers’ compensation law are viewed as abolishing the Indians’ common law cause of action, as depriving the state
*1318
courts of jurisdiction, or rather as a limitation of remedy,
2
it is evident that they are “substantive” provisions which, under
Erie,
a district court sitting in diversity is bound to follow.
See, e.g., Guaranty Trust Co. v. York, supra; Ragan v. Merchants Transfer & Warehouse Co.,
VI
This does not mean that the district court had no federal questions to decide. Issues involving federal law may be involved even when there is no federal question jurisdiction. Therefore, having properly invoked the diversity jurisdiction of the district court, the Indians were not precluded from asserting that federal law, including the Supreme Court’s decision in
Williams v. Lee, supra,
preempts the Arizona workers’ compensation scheme as applied to Indian reservations, thus permitting a suit for damages.
See Woods v. Holy Cross Hospital,
The language of 40 U.S.C. § 290 unambiguously permits application of state workers’ compensation laws to all United States territory within the state. Claims by Indians against non-Indian employers are not matters of “self-governance in purely intramural matters” sufficient to avoid the rule that Indians are subject to such federal laws of general application,
United States v. Farris,
We also agree with the companies that we are required to follow the Supreme Court’s decision in
Johnson v. Kerr-McGee Oil Industries, Inc.,
Thus, we conclude that the district judge erred in dismissing for lack of subject matter jurisdiction. He should have dismissed for failure to state a claim upon which relief could be granted. On this basis, the order of the district court is affirmed.
AFFIRMED.
Notes
. See,
e.g., White Mountain Apache Tribe v. Bracker,
. Workers’ compensation schemes generally deprive the injured worker of his or her independent cause of action against the employer, substituting statutory compensation benefits in its place.
See, e.g., Jackson v. Dravo Corp.,
The Arizona statute thus appears to abolish an employee’s common law and statutory causes of action against covered employers, in the absence of an employee election to reject the right to administrative compensation. Construed in this manner, Arizona law would demonstrate that employers are
immune
from all liability if, as in this case, they have complied with the statute and no exceptions to it apply.
See Johnson v. Kerr-McGee Oil Indus., Inc.,
. We do not mean to suggest that state law necessarily controls all questions of remedy in diversity cases. At least with regard to equitable remedies, it seems clear that “a federal court may afford an equitable remedy for a substantive right recognized by a State even though a State court cannot give it.”
Guaranty Trust Co. v. York,
. In view of our reliance upon the Supreme Court’s summary disposition of
Johnson I,
we have no occasion to consider whether our previous summary affirmance of an order dismissing a parallel lawsuit filed in federal district court,
