Whether a state prisoner may recover damages under § 1983 for allegedly unconstitutional conviction or imprisonment while the conviction or sentence remains outstanding.
Holding
No. A § 1983 damages claim is not cognizable if success would necessarily imply the invalidity of an outstanding conviction or sentence, unless that conviction or sentence has already been invalidated.
Reasoning
The Court began with the overlap between § 1983 and federal habeas corpus. Section 1983 generally does not require a plaintiff to exhaust state remedies, whereas habeas corpus requires a state prisoner to pursue available state remedies first. Under Preiser v. Rodriguez, habeas is the exclusive federal remedy when a prisoner challenges the fact or duration of custody and seeks immediate or speedier release. But Heck sought damages, relief that habeas could not fully provide, so Preiser did not directly resolve his case.
The Court rejected the idea that the question should be answered by adding an exhaustion requirement to § 1983. The proper question is whether the particular damages claim exists under § 1983 at all. A prisoner cannot avoid habeas limitations simply by requesting money rather than release when proving the damages claim would establish that the conviction or sentence itself was unlawful.
Common-law malicious prosecution supplied the closest analogy because it permits recovery for confinement imposed through legal process. A malicious-prosecution plaintiff must show that the prior criminal proceeding terminated favorably. That rule prevents parallel litigation over guilt and probable cause, avoids inconsistent civil and criminal judgments, and prevents a civil tort suit from becoming a collateral attack on an existing criminal conviction.
Applying that principle, the Court held that a plaintiff seeking damages for unconstitutional conviction or imprisonment, or for conduct whose unlawfulness would render a conviction or sentence invalid, must first show favorable termination. The conviction or sentence must have been reversed on direct appeal, expunged by executive order, declared invalid by an authorized state tribunal, or called into question through a federal writ of habeas corpus.
The district court must ask whether a judgment for the § 1983 plaintiff would necessarily imply the invalidity of an outstanding criminal judgment. If it would, the court must dismiss the complaint unless the plaintiff proves that the judgment has already been invalidated. If success would not necessarily demonstrate invalidity, the § 1983 action may proceed, subject to other possible defenses or bars.
Heck's allegations were treated by both lower courts as attacks on the legality of his conviction, and Heck did not timely contest that characterization before the Supreme Court. Because his conviction had not been invalidated, his damages action was properly dismissed. The Court therefore affirmed the Seventh Circuit.
