The Arising-Under Grant

The statute that supplies federal question jurisdiction is short enough to memorize: the district courts have original jurisdiction of all civil actions arising under the Constitution, laws, or treaties of the United States.¹ Original jurisdiction means the power to hear the case in the first instance, as a trial court, rather than on review of someone else's judgment. What repays attention is everything the sentence leaves out. It says nothing about where the parties live, nothing about how much money is at stake, and nothing about how important the dispute looks. Compare the other great grant of original jurisdiction, diversity under 28 U.S.C. § 1332, which requires that the parties be citizens of different states and that the matter in controversy exceed $75,000.² Section 1331 carries neither condition today; early versions of the statute did impose an amount floor, but those requirements have expired and the grant now stands essentially as Congress wrote it in 1875.³

The asymmetry between the two grants is not an oversight, and seeing the reason makes the rule easier to hold. Diversity jurisdiction exists to give an out-of-state litigant a forum insulated from any local preference for the home-state party, and because that concern is about the risk of unfair treatment rather than about the content of the law, Congress can sensibly reserve the federal forum for disputes big enough to be worth the trouble.⁴ Federal question jurisdiction exists for a different reason: a national government whose statutes and Constitution could be construed only by state tribunals has no assurance that its law will be read uniformly or applied hospitably, so Congress opened a trial forum whose institutional business is federal law.⁵ The importance of a federal question does not track the dollars attached to it, since a four-figure wage claim can present a question about the meaning of a federal statute that will govern thousands of later disputes. A dollar threshold would therefore screen out exactly the wrong cases.

That logic produces two concrete results worth keeping side by side. Suppose two residents of Ohio litigate a $4,000 claim under a federal employment statute; the district court has jurisdiction, because the only question § 1331 asks is whether federal law supplies the claim, and shared citizenship and a small sum are both beside the point. Now change only the law that supplies the claim: two Ohio residents fight over a $5 million contract for goods that happened to travel on federally funded highways. There is no diversity, and there is no federal cause of action, so the size and commercial significance of the case buy nothing. In general, arising-under jurisdiction requires the plaintiff to be seeking relief under federal law, such as a federal civil rights or labor statute, and no amount of federal flavor in the surrounding facts substitutes for that.⁶

Because jurisdiction comes from a statute, it attaches to claims rather than to lawsuits, and federal courts therefore analyze subject-matter jurisdiction claim by claim rather than case by case.⁸ Every count in a complaint needs its own statutory ticket of admission, and the ticket may read § 1331, § 1332, or any other jurisdictional statute, but there must be one for each claim.⁹ The supplemental jurisdiction statute, 28 U.S.C. § 1367, is the one companion ticket: a claim with no independent basis may still enter the district court if it travels with a claim that does qualify and shares the proper factual relationship with it. The order of operations matters, because a court cannot exercise supplemental jurisdiction until it already has original jurisdiction over at least one claim in the action; without that anchor there is nothing for the related claim to attach to.¹⁰ So a plaintiff who pleads a federal civil rights claim arising from an arrest and a state-law battery claim arising from the same arrest has one claim inside § 1331 and one claim that must earn its place through § 1367.

Underlying both of those rules is the premise that gives this whole chapter its shape. State courts are generally courts of general jurisdiction and can hear almost any kind of dispute, while the federal district courts are courts of limited jurisdiction that may hear only what they have been affirmatively authorized to hear.¹² Two separate permissions are required. Article III, § 2 marks the outer boundary by extending the judicial power to nine categories of cases, the first of which is cases arising under the Constitution, federal statutes, and treaties.¹³ That provision does not itself staff the lower courts with power, because Congress creates those courts and defines their jurisdiction within the Article III boundary, giving them as much or as little of the judicial power as it chooses.¹⁴ A litigant must therefore clear both hurdles: the case must be one the Constitution permits a federal court to hear, and Congress must actually have conferred jurisdiction over it by statute.¹⁵

One practical consequence follows immediately, and it changes how you read a complaint. Nothing is presumed in favor of the federal forum, so the party invoking § 1331 has to point to the federal law that supplies the claim rather than to reasons the federal court would be the better place to litigate. A plaintiff who argues that federal judges handle complex cases more efficiently, or that the dispute has national significance, has not identified a jurisdictional ticket at all. The same plaintiff who points to a federal statute creating the right sued upon has. Where the court looks for that federal ingredient, and what kind of federal ingredient counts, are the two questions the rest of the chapter answers, and the first of them is settled by the well-pleaded complaint rule.

Constitutional Reach and Statutory Limits

Article III, § 2 extends the judicial power to all cases, in law and equity, arising under the Constitution, the laws of the United States, and treaties made under their authority, and that category stands first among the nine the clause lists.¹⁷ Treaties sit in that sentence alongside statutes, so a suit to stop a federal officer from enforcing a treaty-implementing act presents a federal question as surely as one brought under an ordinary federal statute, which is how Missouri came to sue a United States game warden over enforcement of the Migratory Bird Treaty Act.¹⁸ Courts have read this constitutional language generously. Ever since Osborn v. Bank of the United States, the accepted understanding has been that the constitutional scope of arising-under jurisdiction is broad: it is enough that a question of federal law forms an ingredient of the controversy, whoever injects it into the case and whether or not it ends up being contested.¹⁹ The Court put the same idea in claim-specific terms in Powell v. McCormack, where it treated a suit as arising under the Constitution because the plaintiff's claim would be sustained if the Constitution were given one construction and defeated if it were given another.²⁰

That breadth describes what Congress may give the district courts, and nothing more. Article III does not create the lower federal courts or hand them jurisdiction; it authorizes Congress to establish them, and the power to create carries with it the power to define what those courts may hear within the outer bounds the clause draws.²¹ Congress may therefore impart as much or as little of the judicial power as it thinks appropriate, and for most of the nineteenth century it gave the trial courts very little of the arising-under category, authorizing jurisdiction only over suits under particular federal subjects such as the revenue and patent laws.²² The broad grant came only after the Civil War, when the new amendments expanded federal oversight of the states and Congress doubted that southern state courts would faithfully enforce the new federal civil rights statutes; the Second Judiciary Act of 1875, now codified at § 1331, was the response.²³

Congress wrote the 1875 statute in the Constitution's own words, which invites the natural inference that it meant to hand over the whole constitutional category, and that inference is wrong.²⁴ The Court has said plainly that although the language of § 1331 parallels the Arising Under Clause, it has never held that statutory arising-under jurisdiction is identical to Article III arising-under jurisdiction, and the grant in § 1331 is not in all respects as wide as the potential for federal jurisdiction Article III contains.²⁵ What the narrower reading requires is that federal law be necessary to the plaintiff's own claim: the statute does not reach cases that merely involve federal law unless the federal issue is essential to proving what the plaintiff has pleaded.²⁶ The statutory phrase has never yielded a single precise definition, and the doctrines that give it content, beginning with the well-pleaded complaint rule, are judicial constructions rather than anything visible in the text.²⁷

The gap between the two tests is deliberate, and each side of it has its own reason. The constitutional grant is written broadly because no case touching federal law should be placed permanently beyond the reach of a federal tribunal, and the framers could not know in advance which federal subjects would need a federal forum. The statutory grant is read narrowly because the district courts also have a docket to manage and the states retain the primary job of deciding ordinary contract, tort, and property disputes. Consider what an ingredient test would do if it governed § 1331. Nearly every commercial transaction, employment relationship, and piece of real property in the country is touched somewhere by federal regulation, so a defendant who could point to any federal element would drag an ordinary state-law case into federal court on the strength of an issue the court might never reach. Keying the statute to the plaintiff's own claim screens on the one thing that reliably predicts whether federal law will actually decide the case.

The railway-pass case from the chapter's opening sits exactly on the line. The railroad's defense that the 1906 statute barred renewal of the passes injected a genuine federal ingredient into the controversy, which satisfied the constitutional test and would have let Congress confer district court jurisdiction had it chosen to; what defeated the Mottleys was that the same defense did nothing for them under § 1331, because their own claim was for breach of a contract and rested on state law alone.²⁸ Change the source of the plaintiff's claim and both tests are satisfied at once. In Ex parte Young, the complaint attacked state rate legislation and the penalties attached to it as a taking of property without due process, so the plaintiffs' right to relief depended on a construction of the Fourteenth Amendment, and the Circuit Court had jurisdiction precisely because the case involved the decision of federal questions arising under the Constitution.²⁹ The moving fact in that pair is not how important the federal issue was, nor how certainly it would be litigated, but whether it belonged to the plaintiff's claim or to the defendant's answer.

One feature of the system keeps the narrow statutory rule from burying federal issues in state courts, and it explains how a dispute can be non-federal in the district court yet still reach the Supreme Court. A different statute, 28 U.S.C. § 1257, confers appellate jurisdiction on the Supreme Court over state court decisions of dispositive federal questions, and its reach is not limited by the rules that govern original jurisdiction under § 1331.³⁰ The railway-pass litigation proves the point: after the jurisdictional dismissal the plaintiffs refiled in state court and won, and the Supreme Court then took the case on direct review, reached the federal questions, and ruled for the railroad on both the statutory and constitutional issues.³¹

The second step does the work on almost every exam problem, and the first is rarely contested, so a satisfied constitutional test tells you only that the real question has not yet been answered.³² Students lose points by reasoning in the opposite direction, concluding that a case must belong in federal court because the Constitution would permit it there. That reasoning runs backward: constitutional reach is a necessary condition for the exercise of federal jurisdiction, never a sufficient one.³³

Concurrent and Exclusive Jurisdiction

Everything said so far asks whether a federal district court may hear a claim arising under federal law. A separate question is whether the plaintiff must go there, and the usual answer is that he need not. When federal subject-matter jurisdiction exists, it is ordinarily concurrent with the state courts, so the litigant chooses which system will try the case.³⁵ The reason lies in how the two systems are built: the general trial courts of each state have subject-matter jurisdiction over almost any kind of case, unless the subject has been committed exclusively to a specialized state tribunal or to the federal courts.³⁶ A plaintiff who holds a federal civil rights claim may therefore file it in state court, because § 1331 opens the federal door without closing the state one, and Congress has not made jurisdiction over those claims exclusive.³⁷ Suppose an employee sues his former employer under the federal age discrimination statute, and both are citizens of the same state. Counsel may file that action in state court, because the statute does not direct that such suits be brought in a federal forum.³⁸

The state court, for its part, has no option to turn the case away because of the law it rests on. Unless an Act of Congress has conferred jurisdiction of a federal claim on the federal courts exclusively, the jurisdiction is concurrent, and a state court that refuses the claim on the sole ground that it is federal engages in unconstitutional discrimination against the federal right.³⁹ That obligation is older than § 1331 and rests on the Supremacy Clause itself: the Constitution contemplated that cases within the federal judicial power would arise in state courts in the ordinary course of their business, and article six makes the Constitution, federal statutes, and treaties the supreme law of the land, binding the judges in every state.⁴⁰ State judges, pronouncing the law applicable to the case before them, must decide according to federal law as well as state law.⁴¹ The practical reasons point the same way. The federal trial bench is deliberately small, and routing every statutory claim into it would swamp a system designed for a limited docket, while a plaintiff with a modest federal claim often lives nearer a county courthouse than a federal one.

Congress can override that default, and in a few fields it has. The federal courts have exclusive jurisdiction over actions based on patents and copyrights under 28 U.S.C. § 1338 and over all proceedings in bankruptcy under 28 U.S.C. § 1334, so no action on those subjects may be brought in a state court.⁴² What unites those fields is that each creates a nationally uniform entitlement whose worth depends on being construed the same way everywhere. A patent that means one thing in Ohio and another in Nevada is not worth what the statute promised, and a bankruptcy estate administered under fifty different constructions could not distribute assets coherently. Concentrating those cases in one court system, under one appellate hierarchy, is how the uniformity is purchased. The consequence for the pleader is blunt: change the earlier hypothetical from an age discrimination claim to a copyright infringement claim, and the state court lacks subject-matter jurisdiction and must dismiss, however convenient that forum would be.⁴³

The allocation runs in the other direction as well. Probate and divorce actions fall within the exclusive jurisdiction of the state courts and in most instances belong before specialized state tribunals built to handle them, and that division is historic rather than statutory, observed by both systems although neither is compelled by statute or Constitution to observe it.⁴⁴ So diverse spouses cannot obtain a federal divorce decree merely because § 1332 would otherwise admit their dispute.

The defendant is not left without a say when the plaintiff chooses state court, and the next reading takes up the mechanism in detail: removal under 28 U.S.C. § 1441(a) is proper only if the federal court would have had jurisdiction had the plaintiff filed there in the first place.⁴⁵

One structural safeguard keeps concurrent jurisdiction from fracturing federal law into fifty readings. The Supreme Court's appellate power extends to cases pending in state courts, and the Judiciary Act's twenty-fifth section authorized review by writ of error of a final state judgment drawing in question the validity or construction of a federal treaty, statute, or authority where the decision went against the federal right asserted.⁴⁶ In Martin v. Hunter's Lessee the Court reasoned that without such review a discretionary power in Congress to withhold lower federal courts would defeat the Constitution's own command that the judicial power extend to all cases arising under federal law.⁴⁷ State judges therefore decide federal questions in the first instance, and a single federal court corrects them at the end.
