asserting that the case had been improperly removed on federal-question grounds. The District Court denied the motion, holding that removal on federal-question grounds was proper at the time of removal, Hurt “waived any non-jurisdictional objection to the impropriety of removal,” Hurt v. Dow Chemical Company, No. 90-0783-C(3), slip op. 3 (E.D.Mo. May 22, 1991), and that diversity jurisdiction existed even if federal-question jurisdiction did not. Hurt then voluntarily dismissed her remaining claims and appealed to this Court.
The sole question we address here is, was removal proper? The defendants argue that it was proper because the FIFRA pre-emption defense gave the District Court federal-question jurisdiction, and, in the alternative, because the Court had original diversity jurisdiction (or would have had it if plaintiff had originally filed her action in the District Court). If the defendants are wrong, and we believe that they are, the District Court erred in failing to grant plaintiffs motion to remand.
What is required to invoke federal-court jurisdiction depends on whether it is the plaintiff or the defendant who wants to invoke it. A plaintiff may bring suit in federal court if her claim “arises under” federal law. See 28 U.S.C. § 1331. Even if it does not, she may bring a state cause of action in federal court if she is suing a citizen of a state different from her own. See 28 U.S.C. § 1332. In both of these situations, the court has original jurisdiction. While a defendant, of necessity, cannot invoke the federal court’s original jurisdiction, it may, in some situations, invoke the court’s removal jurisdiction. Because the requirements to invoke the court’s removal jurisdiction are often identical to those for invoking its original jurisdiction, confusion in this area of the law is common. The requirements for both relate to the same end, that is, federal jurisdiction. They are not, however, alternative means for a defendant to reach that end. Defendants must come within the court's removal jurisdiction. The concept of original jurisdiction has no meaning with respect to a defendant.
We first address the defendants’ initial ground for removal, federal-question removal jurisdiction. Title 28 U.S.C. § 1441(a) allows a case to be removed if “the district courts of the United States have original jurisdiction.” Defendants rely first on 28 U.S.C. § 1331, granting jurisdiction “of all civil actions arising under” federal law. The defendants argue that the federal defense of pre-emption of plaintiff’s claims by FIFRA causes the case to “arise under” federal law. We note, as do the parties, that there is a longstanding limitation on this jurisdictional ground called the well-pleaded complaint rule. Under this doctrine, an action “arises under” federal law only if the federal question appears on the face of a properly pleaded complaint. In other words, “a federal defense, including the defense of pre-emption, 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,” Franchise Tax Board of California v. Construction Laborers Vacation Trust, 463 U.S. 1, 14, 103 S.Ct. 2841, 2848, 77 L.Ed.2d 420 (1983), does not cause the plaintiff’s claim to arise under federal law.
The defendants claim, however, that this case fits into an exception known as the “complete pre-emption doctrine.” The Supreme Court has held on rare occasions that federal law is so dominant in a particular area, the pre-emptive force of a federal statute 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.” Metropolitan Life Ins. Co. v. Taylor, 481 U.S. 58, 65, 107 S.Ct. 1542, 1547, 95 L.Ed.2d 55 (1987) (holding that section 502(a)(1)(B) of ERISA completely pre-empts the field). In such a situation, the federal law so occupies the field that any complaint alleging facts that come within the statute’s scope necessarily “arises under” federal law, even if the plaintiff pleads a state-law claim only. It is not just that a preemption defense is present: the claim is completely federal from the beginning.
In the present case, however, this is not true. No one claims that plaintiff would have a FIFRA-created cause of action for the facts she alleges. Defendants argue that the language in FIFRA forbidding states from “impos[ing] or con-
