Federal Question Jurisdiction Guide
Federal question jurisdiction under 28 U.S.C. Section 1331 gives federal courts authority to hear cases "arising under the Constitution, laws, or treaties of the United States." This is the most straightforward basis for federal jurisdiction and reflects the idea that federal courts should interpret and apply federal law. The well-pleaded complaint rule, established in Louisville & Nashville Railroad Co. v. Mottley (1908), limits federal question jurisdiction to cases where the federal issue appears on the face of the plaintiff's complaint — not in anticipated defenses, counterclaims, or replies.
The standard case of federal question jurisdiction is simple: the plaintiff brings a claim created by federal law. When Congress creates a federal cause of action — such as a Title VII employment discrimination claim, a Section 1983 civil rights claim, or an antitrust claim under the Sherman Act — any suit brought under that statute arises under federal law. The more difficult cases involve state-law claims that turn on an embedded federal issue. Under the framework articulated in Grable & Sons Metal Products, Inc. v. Darue Engineering (2005), a state-law claim qualifies for federal question jurisdiction only if it (1) necessarily raises a federal issue, (2) that is actually disputed, (3) substantial, and (4) capable of resolution in federal court without disturbing the congressionally approved balance of federal and state judicial responsibilities.
The well-pleaded complaint rule has significant practical consequences. It means that a case cannot be removed to federal court based on a federal defense, even if everyone knows the defense is the central issue in the case. The Mottley plaintiff, for example, alleged a breach of contract — a state-law claim — even though the defense rested on a federal statute. Because the federal issue appeared only in the anticipated defense, not in the complaint, the Supreme Court held that federal question jurisdiction did not exist. This rule forces students to focus exclusively on the plaintiff's chosen cause of action when analyzing jurisdiction.
Understanding the distinction between "creation" jurisdiction (the claim is created by federal law) and "embedded" federal question jurisdiction (a state-law claim raises a substantial federal issue) is critical for exam success. Most federal question cases on exams involve the easier creation analysis, but professors frequently test the Grable framework to assess whether students can navigate the more nuanced situations. Students should also be aware of the complete preemption doctrine, under which certain state-law claims are deemed to be federal claims for jurisdictional purposes even though the plaintiff has framed them as state-law claims.
Key Elements
- 1
Well-Pleaded Complaint Rule
The federal question must appear on the face of the plaintiff's complaint as an essential element of the claim. Federal defenses, counterclaims, and anticipated replies do not count.
- 2
Federal Cause of Action (Creation Test)
The simplest basis: the plaintiff's claim is created by a federal statute, constitutional provision, or treaty. If the cause of action is federal, jurisdiction exists under Section 1331.
- 3
Embedded Federal Issue (Grable Test)
A state-law claim can qualify for federal question jurisdiction if it necessarily raises a disputed, substantial federal issue that can be resolved without disturbing the federal-state balance.
- 4
Substantiality
For embedded federal questions, the federal issue must be substantial — a pure question of federal law with broad significance, not just a fact-bound application of a federal standard to a particular case.
- 5
Complete Preemption
Some federal statutes so completely preempt a field that state-law claims within that field are treated as federal claims for jurisdictional purposes (e.g., ERISA Section 502(a), LMRA Section 301). This is an exception to the well-pleaded complaint rule.
Step-by-Step Analysis Flowchart
- Step 1: Examine the plaintiff's complaint: Identify the cause(s) of action as pleaded by the plaintiff.
- Step 2: Determine whether any claim is created by federal law (a federal statute, constitutional provision, or treaty).
- Step 3: If the claim is created by federal law, federal question jurisdiction exists — the analysis is straightforward.
- Step 4: If the claim is created by state law, examine whether it necessarily raises a federal issue as an element of the state-law claim.
- Step 5: Apply the Grable test: Is the federal issue (a) necessarily raised, (b) actually disputed, (c) substantial, and (d) resolvable in federal court without disturbing the federal-state balance?
- Step 6: Consider whether the complete preemption doctrine applies: Has Congress so completely preempted the field that the state-law claim is recharacterized as federal?
- Step 7: Confirm that the federal question appears on the face of the well-pleaded complaint, not merely in an anticipated defense or counterclaim.
- Step 8: If federal question jurisdiction exists, confirm that no other jurisdictional defect (e.g., standing, mootness, ripeness) bars the federal court from hearing the case.
Key Rules
- The well-pleaded complaint rule limits federal question jurisdiction to cases where the federal issue appears on the face of the plaintiff's complaint (Mottley).
- A case 'arises under' federal law when the plaintiff's cause of action is created by federal law — this is the most common and straightforward basis for Section 1331 jurisdiction.
- State-law claims with embedded federal issues qualify only if the federal element is (1) necessarily raised, (2) actually disputed, (3) substantial, and (4) consistent with the federal-state balance (Grable).
- The artful pleading doctrine prevents a plaintiff from avoiding federal jurisdiction by framing an inherently federal claim as a state-law claim.
- Complete preemption converts certain state-law claims into federal claims for jurisdictional purposes, even though the plaintiff chose to plead state law (ERISA, LMRA).
- Federal question jurisdiction does not require an amount-in-controversy threshold — any amount of damages suffices.
Common Exam Patterns
Plaintiff brings a state-law contract claim, but the only real issue is whether a federal regulation permits the defendant's conduct — tests Grable's embedded federal question analysis.
Plaintiff sues under state law knowing the defendant will raise a federal preemption defense — tests the well-pleaded complaint rule (the defense does not create jurisdiction).
Plaintiff sues an employer under state law for benefits denied under an ERISA plan — tests complete preemption doctrine.
Plaintiff brings both a Section 1983 claim and a state tort claim — tests federal question jurisdiction for the federal claim and supplemental jurisdiction for the state claim.
Declaratory judgment action where the natural plaintiff (the one who would sue for coercive relief) has the federal claim, but the actual plaintiff in the DJ action does not — tests the 'coercive action' realignment analysis.
Plaintiff sues under a federal statute that does not create a private right of action — tests whether Section 1331 requires an express cause of action (it does not, but the claim may still fail on the merits).
Landmark Cases
Louisville & Nashville Railroad Co. v. Mottley (1908)
Established the well-pleaded complaint rule: federal question jurisdiction exists only if the federal issue appears on the face of the plaintiff's complaint, not in anticipated defenses.
Grable & Sons Metal Products, Inc. v. Darue Engineering (2005)
Articulated the four-part test for when a state-law claim with an embedded federal issue qualifies for federal question jurisdiction: necessarily raised, actually disputed, substantial, and consistent with the federal-state balance.
Gunn v. Minton (2013)
Applied the Grable test to hold that a state-law legal malpractice claim raising a patent-law issue did not satisfy the substantiality requirement because the federal issue was fact-bound and situation-specific.
Merrell Dow Pharmaceuticals Inc. v. Thompson (1986)
Held that a state-law tort claim incorporating a federal regulatory standard (FDCA) did not create federal question jurisdiction, foreshadowing the Grable framework's substantiality and balance requirements.
Tips for Success
- The well-pleaded complaint rule is the threshold question — always analyze what appears on the face of the complaint before considering defenses.
- The creation test (plaintiff sues under a federal statute) is straightforward. Spend your exam time on the harder Grable embedded-question analysis when state-law claims raise federal issues.
- Substantiality under Grable turns on whether the federal issue is a pure question of law with broad significance or a fact-bound application to particular facts — the latter is not substantial (Gunn v. Minton).
- Complete preemption is narrow and applies only when Congress intended to completely displace state law in a particular area. The big examples are ERISA Section 502(a) and LMRA Section 301.
- Federal question jurisdiction has no amount-in-controversy requirement. If you can find a federal claim, you never need to worry about the $75,000 threshold.
- On removal questions, remember that a federal defense — even an obvious preemption defense — does not support removal under the well-pleaded complaint rule.
- Declaratory judgment cases can be tricky: courts look to the 'character of the threatened action,' not the declaratory judgment complaint, to determine if a federal question exists.
