Rooker–Feldman Doctrine¶
A narrow U.S. federal-jurisdiction doctrine barring lower federal district courts from hearing cases brought by state-court losers whose alleged injury is caused by a completed state judgment and whose federal suit invites review and rejection of that judgment.
Core Idea¶
Rooker–Feldman is a forum-allocation doctrine, not a universal second-litigation bar. It prevents a federal district court from being used as an appellate tribunal to undo a state-court judgment.
Modern analysis is element-specific and narrow. Courts must identify the injury and relief rather than infer a bar merely because state and federal cases overlap.
Scope of Application¶
- Federal civil procedure. Tests district-court subject-matter jurisdiction.
- Federalism. Allocates review between state systems and the Supreme Court.
- Litigation strategy scholarship. Distinguishes independent claims and remedies.
- Judicial administration. Separates jurisdiction, preclusion, abstention, and statutory review.
Clarity¶
State jurisdiction, relevant date, state tribunal and judicial act, judgment status, parties and privity, alleged injury source, federal claim and requested relief, timing, whether rejection is necessary, controlling Supreme Court and circuit precedent, statutory jurisdiction/exception, and separate treatment of preclusion and abstention. This is descriptive, not case advice. Inclusion test: Require the narrow conjunction under controlling current precedent: qualifying state judgment, state-court loser, judgment-caused injury, prior timing, and requested district-court review/rejection, subject to statutory context. Exclusion test: Exclude ordinary claim or issue preclusion, abstention, a federal claim for independent misconduct, review of nonjudicial administrative action, parallel litigation, and a generic rule that any issue discussed in state court is barred. Nearest boundary: Preclusion accepts federal jurisdiction but gives prior judgments binding effect under applicable law; Rooker–Feldman is a limited subject-matter-jurisdiction bar. Exit condition: Application changes with judgment finality, claimant party status, source of injury, relief sought, timing, judicial nature of the state act, statutory exceptions, and evolving Supreme Court/circuit authority. Common misclassifications: It is not res judicata. It does not bar every claim related to state litigation. It does not authorize district-court review merely because a claim is federal. Its current scope must be checked against dated authority. Nearest named distinctions: Claim preclusion: Is an affirmative effect of prior judgment, not necessarily a jurisdictional bar. Younger abstention: Addresses certain ongoing state proceedings. Habeas review: Operates under express federal statutory jurisdiction. Removal: Moves qualifying pending cases and is not appellate review of a completed judgment.
Manages Complexity¶
Federal pleadings can describe the same events as constitutional injury, opposing-party misconduct, or harm from judgment. Small changes in causal theory and remedy alter the jurisdictional result.
Abstract Reasoning¶
- Identify the exact state judicial decision and its procedural status.
- Determine whether the federal plaintiff was the relevant state-court loser.
- Trace the alleged injury to judgment or independent conduct.
- Ask whether granting relief requires review and rejection of the judgment.
- Then analyze statutory exceptions, preclusion, abstention, and merits separately under current authority.
Knowledge Transfer¶
Element-specific forum analysis transfers to other jurisdiction doctrines, but Rooker–Feldman is specific to the U.S. state/federal appellate structure. It should not be generalized to foreign judgments or administrative review.
