Federal-question jurisdiction
Federal-question jurisdiction exists when federal law creates the claim or a necessarily raised, actually disputed, substantial federal issue may be resolved in federal court without disturbing the federal-state balance.

- Apply the well-pleaded-complaint rule; ignore anticipated defenses and federal counterclaims.
- A federal ingredient must appear in the plaintiff's properly pleaded claim.
- Declaratory-judgment actions are analyzed by asking whether the coercive action would arise under federal law.
- A private federal cause of action usually suffices; an embedded issue requires the narrower substantial-federal-question test.
Attack sequence
1Is federal law an element of the claim?
2Is the issue substantial to the federal system, not merely important to the parties?
3Would federal jurisdiction upset the congressionally approved division of labor?
Traps and exceptions
!A federal defense never supplies ordinary federal-question jurisdiction.
!A complaint cannot manufacture jurisdiction by artful reference to federal law.
A patient sues a drug manufacturer under state negligence law and alleges that violation of a federal labeling rule proves breach. The federal statute creates no private action.
The federal rule may be evidence of breach, but that alone does not necessarily create federal-question jurisdiction. Analyze whether the federal issue is necessarily raised, disputed, systemically substantial, and consistent with the federal-state balance.
Essay-ready formulationA federal court has federal-question jurisdiction only when a federal issue appears on the face of the well-pleaded complaint and satisfies the federal cause-of-action or embedded-federal-issue route.
