Whether Phillips's declaratory action against Skelly and Stanolind arose under federal law within the meaning of federal-question jurisdiction.
Holding
No. The claims against Skelly and Stanolind had to be dismissed because Phillips's underlying claim was a state-law contract claim, and the anticipated federal issue appeared only as a prospective defense.
Reasoning
The Declaratory Judgment Act is procedural: it expands the remedies a federal court may provide, but it does not expand the classes of cases over which federal courts have subject-matter jurisdiction. A plaintiff seeking declaratory relief must therefore establish the same jurisdictional foundation that would have been required in an ordinary coercive action for damages, injunction, or specific performance.
Had Phillips sued to enforce the gas-purchase contracts through damages or specific performance, its claim would have arisen under the state law governing those contracts. Phillips could not turn that state-law claim into a federal one merely because the producers would defend by arguing that the Federal Power Commission had not issued the certificate contemplated by the contracts.
This application follows the well-pleaded-complaint rule. A federal question must appear in the plaintiff's own properly pleaded claim, without reliance on an anticipated defense or a response to such a defense. Artful pleading cannot create federal jurisdiction by seeking a declaration that an expected federal-law defense will fail.
Allowing declaratory plaintiffs to invoke federal jurisdiction whenever they anticipated a federal defense would divert a large body of state-law litigation into federal court. It would also force federal courts to resolve unsettled questions of local law and would undermine Congress's continuing policy of limiting lower federal courts' jurisdiction.
