Federal Question Meaning
A federal question is a legal issue involving the U.S. Constitution, federal law or a U.S. treaty. Whether that issue gives a federal court jurisdiction—authority to hear a case—is a separate question: mentioning federal law does not automatically establish federal-question jurisdiction.
Federal-question jurisdiction generally depends on the plaintiff’s own claim arising under federal law as properly pleaded. An anticipated federal defense usually cannot supply that basis. A narrow category of state-law claims can qualify because of an embedded federal issue, but only under a demanding test.
Three layers: Constitution, statute and claim
Article III, section 2 of the Constitution places cases arising under the Constitution, federal laws and treaties within the federal judicial power. That constitutional category and Congress’s grant of jurisdiction to federal trial courts are distinct.
28 U.S.C. section 1331 gives district courts original jurisdiction over civil actions arising under the Constitution, laws or treaties of the United States. “Original” concerns hearing the action in the first instance; it is not permission for a district court to review every legal disagreement with another judge.
The practical sequence is constitutional category → statutory grant → the claim actually pleaded. A federal subject somewhere in the background does not complete that sequence. Nor does jurisdiction establish that a plaintiff will win or that the asserted right provides the remedy requested.
A four-step reading guide
- Identify the claim seeking relief. What legal right does the plaintiff say was violated, and which law supplies the cause of action? Federal law creating that cause is the usual route to arising-under jurisdiction.
- Read the claim rather than a predicted response. The well-pleaded-complaint rule ordinarily looks to the plaintiff’s own claim in the complaint. Adding a paragraph anticipating a federal defense does not convert a state-law cause into a federal one.
- If state law creates the claim, examine the embedded issue. All four requirements described below must be met; a necessary federal issue alone is insufficient.
- Keep other jurisdictional bases separate. A state-law claim that fails the federal-question route may involve diversity or supplemental jurisdiction, but those have their own requirements. Do not assume failure of one test establishes another.
This guide organizes the questions; it is not a substitute for identifying the applicable statute and the actual claims.
The narrow embedded-federal-issue test
In Gunn v. Minton, 568 U.S. 251 (2013), the Supreme Court explained that a state-law claim can fall within a small arising-under category if its federal issue is:
- Necessarily raised: Resolving the claim requires deciding the federal issue.
- Actually disputed: The parties genuinely disagree about that issue.
- Substantial: Its importance extends to the federal system, rather than merely being important to these litigants.
- Consistent with the federal-state balance: Federal adjudication can occur without disrupting Congress’s intended division of responsibilities.
Gunn applied that framework to federal patent jurisdiction under section 1338(a), explaining that the arising-under language is interpreted consistently with section 1331. It distinguished a direct patent infringement claim, created by federal law, from a later state-law malpractice claim about the patent lawyers’ work.
The malpractice dispute required a hypothetical inquiry into whether the earlier patent case would have turned out differently. That did not make it sufficiently significant to the federal system. The state malpractice claim did not become a federal patent case merely because answering it required patent-law analysis.
The same opinion contrasts Grable, where a state quiet-title dispute turned on the IRS’s compliance with federal tax-sale notice requirements. The government’s broader interest in the administration of those sales supported federal jurisdiction. The lesson is not that every tax reference qualifies; the nature and wider significance of the precise issue matter.
Mottley: a real federal issue, but the wrong source of jurisdiction
In Louisville & Nashville Railroad Co. v. Mottley, 211 U.S. 149 (1908), a couple sought enforcement of a railroad’s promise to provide travel passes. Their complaint anticipated the railroad’s reliance on a federal statute restricting passes and argued against that defense, including a constitutional objection.
The Supreme Court held that this was insufficient for arising-under jurisdiction. The couple’s own cause was the contract claim; the federal issue appeared through the expected defense and response to it. Neither party had challenged jurisdiction, but the Court addressed the defect and directed dismissal.
For an analogous invented example, a seller’s ordinary state contract claim does not become federal merely because the buyer is expected to argue that a federal regulation excuses performance. The regulation may be important to the dispute without supplying the seller’s federal cause of action. A genuinely embedded issue requires the separate four-part analysis, not a prediction that federal law will be discussed.
Compare the three jurisdictional routes
Route | What supplies the basis? |
|---|---|
Federal question | The action arises under federal law, usually because federal law creates the claim, or through the narrow embedded-issue route. Section 1331 has no general minimum-dollar requirement. |
Ordinary diversity under section 1332(a) | Qualifying citizenship and an amount exceeding $75,000, excluding interest and costs. For ordinary state-citizen diversity, complete diversity is required; merely living in different places is insufficient. |
Supplemental jurisdiction | An existing action within original jurisdiction and sufficiently related additional claims forming the same constitutional case, subject to statutory limits and possible refusal. |
The current diversity statute sets its own citizenship configurations and amount requirement. A high-value state contract dispute is not a federal question simply because it exceeds $75,000.
Section 1367 governs supplemental jurisdiction. It includes restrictions in diversity-only cases and circumstances in which a court may decline related claims. Supplemental jurisdiction does not create an independent federal anchor where none exists.
Why constitutional language is not the whole answer
The Federal Judicial Center’s history explains that Congress did not give lower federal courts a lasting general federal-question grant until 1875, despite Article III’s earlier constitutional language. Mottley later clarified the complaint-focused limitation. Congress removed section 1331’s general amount-in-controversy requirement in 1980, as the current statute’s amendment notes record.
That history explains the distinction: constitutional permission, Congress’s statutory choices and judicial interpretation each do work. The term “federal question” cannot replace any of them.
Common mistakes
- Treating a citation to the Constitution as sufficient by itself.
- Relying on an expected federal defense rather than the plaintiff’s claim.
- Assuming any federal issue inside a state-law case passes Gunn’s four-part test.
- Confusing importance to the parties with importance to the federal system.
- Importing diversity’s $75,000 threshold into section 1331.
- Equating authority to hear a case with a decision that the claim succeeds.
Frequently asked questions
What is an example of a federal question?
A direct patent infringement claim raises federal questions under the patent laws. Gunn’s malpractice example shows the limit: a state-law damages claim involving a hypothetical patent issue does not automatically arise under federal law. The source of the claim and the governing jurisdiction statute both matter.
Is section 1331 itself a federal question?
It is the statutory jurisdictional grant, not the underlying dispute or an automatic cause of action. The particular civil action must satisfy its arising-under requirement.
Is $75,000 required?
Section 1331 has no general amount-in-controversy minimum. The ordinary section 1332(a) diversity threshold is a separate rule. Special statutes and other requirements must still be checked.
Is a federal defense enough?
Ordinarily, no. Mottley illustrates why anticipating the defense in the complaint does not change the source of the plaintiff’s own cause of action.
Who can overrule a federal judge?
Review follows the appropriate appellate process. For example, 28 U.S.C. section 1291 addresses courts-of-appeals review of final district-court decisions, with stated exceptions. Calling a disagreement a “federal question” does not itself create an appeal or establish the proper review route.
Quick summary: Locate the federal issue in the plaintiff’s claim, distinguish a federal cause from a defense, and apply every embedded-issue requirement when state law supplies the cause. Then assess the actual statutory basis for federal-court authority.
