Also known as: federal question · federal-question jurisdiction · federal question jurisdiction · 28 U.S.C. § 1331
Written by attorneys · grounded in primary & secondary sources — see below
A basis for federal subject-matter jurisdiction that exists when a plaintiff's well-pleaded complaint asserts a right to relief created by the Constitution, a federal statute, or a treaty. Jurisdiction may arise even without an express private right of action if the claim rests directly on federal law. Anticipated federal defenses or counterclaims cannot create this jurisdiction.
Forrest Falconer sued federal agents in district court after an office search and document seizure, alleging violations of Fourth and Fifth Amendment rights. The complaint sought damages directly under the Constitution without citing any statutory cause of action. The court exercised federal question jurisdiction because the claim rested on federal constitutional provisions.
Felicity French filed a state-law nuisance suit in state court against a chemical plant. The complaint mentioned federal pollution permits only to predict the defendant's likely compliance defense. The defendant removed on federal question grounds, but the district court remanded because the well-pleaded complaint asserted only state claims.

Fatou Fall sued in federal court for copyright infringement of climate maps and added a state unfair-competition claim arising from the same unauthorized copying and submissions. The court exercised supplemental jurisdiction over the state claim because both counts shared the same operative facts.
Farid Farahani brought a state contract action in state court and included allegations about a likely federal regulatory defense. The defendant removed, claiming federal question jurisdiction. The district court remanded because the complaint's reference to federal law appeared only in anticipation of the defense.
Floyd Franklin asserted a federal copyright claim and a related state unfair-competition claim in one complaint. Both claims stemmed from the same unauthorized use of protected maps submitted to a state agency. The court exercised supplemental jurisdiction because the claims derived from a common nucleus of operative fact.
Fernando Farrell sued federal officers after an unauthorized search and seizure of servers, pleading damages directly under the Fourth and Fifth Amendments.

No. The well-pleaded complaint rule limits the inquiry to the plaintiff's own cause of action. A federal issue raised only in the answer or counterclaim cannot support arising-under jurisdiction.
Supporting sources
A federal court may exercise supplemental jurisdiction over a state claim that shares a common nucleus of operative fact with the federal claim so that the plaintiff would ordinarily try both in one proceeding.
Supporting sources
