Also known as:implied causes of action · implied private cause of action · implied right of action
Written by attorneys · grounded in primary & secondary sources — see below
A right to relief that a plaintiff may assert directly under the Constitution or a federal statute even though Congress has not expressly authorized a private damages action. The existence of federal question jurisdiction turns on whether the complaint alleges such a right and is not wholly insubstantial or frivolous. Whether an implied remedy should ultimately be recognized is a merits question separate from jurisdiction.

Protester Seeks Constitutional Damages
Ilana Isaacs stood on a public sidewalk outside a federal building and livestreamed a protest. Federal security officers detained her, seized her phone, and held her for questioning without a warrant. She sued the agency in federal court alleging violations of the Fourth and Fifth Amendments and seeking damages directly under the Constitution. The court held that her complaint presented a substantial federal question supporting jurisdiction even without an express statutory damages remedy.
Shareholder Challenges Proxy Statement
Ines Ibarra owned shares in a corporation that merged after management issued a misleading proxy statement. She sued under section 14(a) of the Securities Exchange Act alleging the false statements caused the merger. The court recognized her implied private right of action because the statute created a federal duty whose violation supported a claim for relief even without an express damages provision.

Detainee Alleges Supervisory Liability

Investor Claims Securities Fraud Loss

Shareholder Challenges Short-Form Merger
Israel Irving held shares in a corporation whose majority owner effected a short-form merger at an allegedly unfair price. He sued under Rule 10b-5 claiming breach of fiduciary duty through the merger. The court declined to recognize an implied cause of action because the claim was essentially a state-law fiduciary breach rather than federal securities fraud.
Santa Fe Industries, Inc. v. Green430 U.S. 462 (1977)
Bank Seeks Aiding-and-Abetting Liability
Ian Iverson's bank extended credit to a borrower who later defaulted after an indenture trustee allegedly aided the borrower's fraud. The bank sued the trustee under Rule 10b-5 claiming an implied aiding-and-abetting cause of action.

Common questions
Frequently Asked
4
Does the absence of an express damages remedy defeat federal question jurisdiction?+
No. A complaint that alleges a right to relief directly under the Constitution or federal law supports federal question jurisdiction even without an express remedial provision, provided the claim is not wholly insubstantial or frivolous.
Supporting sources
When does an implied constitutional damages claim become too insubstantial for jurisdiction?+
A claim is too insubstantial only when it is wholly frivolous or clearly foreclosed by precedent on its face. Questions about whether an implied remedy should be recognized, or whether sovereign immunity bars relief, are merits issues that do not defeat jurisdiction at the pleading stage.
Supporting sources
Can a plaintiff create federal question jurisdiction by anticipating a federal defense?+
No. Under the well-pleaded complaint rule, federal question jurisdiction exists only when the plaintiff's own claim arises under federal law. Allegations that merely anticipate or rebut a federal defense, such as preemption, do not support jurisdiction.
Supporting sources
Does pleading parallel state-law claims defeat federal question jurisdiction over a constitutional count?+
No. A plaintiff may plead both federal and state claims arising from the same facts. As long as one count asserts a nonfrivolous right to relief directly under federal law, the court has federal question jurisdiction over that count and may exercise supplemental jurisdiction over the related state claims.
