*2153Petitioner Edward McDonough alleges that respondent Youel Smith fabricated evidence and used it to pursue criminal charges against him. McDonough was acquitted, then sued Smith under
I
This case arises out of an investigation into forged absentee ballots that were submitted in a primary election in Troy, New York, in 2009. McDonough, who processed the ballots in his capacity as a commissioner of the county board of elections, maintains that he was unaware that they had been forged. Smith was specially appointed to investigate and to prosecute the matter.
McDonough's complaint alleges that Smith then set about scapegoating McDonough *2154(against whose family Smith harbored a political grudge), despite evidence that McDonough was innocent. Smith leaked to the press that McDonough was his primary target and pressured him to confess. When McDonough would not, Smith allegedly fabricated evidence in order to inculpate him. Specifically, McDonough alleges that Smith falsified affidavits, coached witnesses to lie, and orchestrated a suspect DNA analysis to link McDonough to relevant ballot envelopes.
Relying in part on this allegedly fabricated evidence, Smith secured a grand jury indictment against McDonough. McDonough was arrested, arraigned, and released (with restrictions on his travel) pending trial. Smith brought the case to trial a year later, in January 2012. He again presented the allegedly fabricated testimony during this trial, which lasted more than a month and ended in a mistrial. Smith then reprosecuted McDonough. The second trial also lasted over a month, and again, Smith elicited allegedly fabricated testimony. The second trial ended with McDonough's acquittal on all charges on December 21, 2012.
On December 18, 2015, just under three years after his acquittal, McDonough sued Smith and other defendants under § 1983 in the U. S. District Court for the Northern District of New York. Against Smith, McDonough asserted two different constitutional claims: one for fabrication of evidence, and one for malicious prosecution without probable cause. The District Court dismissed the malicious prosecution claim as barred by prosecutorial immunity, though timely. It dismissed the fabricated-evidence claim, however, as untimely.
McDonough appealed to the U. S. Court of Appeals for the Second Circuit, which affirmed.
The Court of Appeals held that McDonough's fabricated-evidence claim accrued, and thus the limitations period began to run, "when (1) McDonough learned that the evidence was false and was used against him during the criminal proceedings; and (2) he suffered a loss of liberty as a result of that evidence." Ibid . This rule, in the Second Circuit's view, followed from its conclusion that a plaintiff has a complete fabricated-evidence claim as soon as he can show that the defendant's knowing use of the fabricated evidence caused him some deprivation of liberty.
As the Second Circuit acknowledged, id ., at 267, other Courts of Appeals have held that the statute of limitations for a fabricated-evidence claim does not begin to run until favorable termination of the challenged criminal proceedings.
II
The statute of limitations for a fabricated-evidence claim like McDonough's *2155does not begin to run until the criminal proceedings against the defendant (i.e., the § 1983 plaintiff) have terminated in his favor. This conclusion follows both from the rule for the most natural common-law analogy (the tort of malicious prosecution) and from the practical considerations that have previously led this Court to defer accrual of claims that would otherwise constitute an untenable collateral attack on a criminal judgment.
A
The question here is when the statute of limitations began to run. Although courts look to state law for the length of the limitations period, the time at which a § 1983 claim accrues "is a question of federal law," "conforming in general to common-law tort principles." Wallace v. Kato ,
An accrual analysis begins with identifying " 'the specific constitutional right' " alleged to have been infringed. Manuel v. Joliet , 580 U. S. ----, ----,
As noted above, this Court often decides accrual questions by referring to the common-law principles governing analogous torts. See Wallace ,
Relying on our decision in Heck , McDonough analogizes his fabricated-evidence claim to the common-law tort of malicious prosecution, a type of claim that accrues only once the underlying criminal proceedings have resolved in the plaintiff's favor.
Common-law malicious prosecution requires showing, in part, that a defendant instigated a criminal proceeding with improper purpose and without probable cause. Restatement (Second) of Torts § 653 ; see also Dobbs § 586, at 388-389; Prosser & Keeton § 119, at 871.
We follow the analogy where it leads: McDonough could not bring his fabricated-evidence claim under § 1983 prior to favorable termination of his prosecution. As Heck explains, malicious prosecution's *2157favorable-termination requirement is rooted in pragmatic concerns with avoiding parallel criminal and civil litigation over the same subject matter and the related possibility of conflicting civil and criminal judgments. See id ., at 484-485,
Heck confirms the strength of this analogy. In Heck , a prisoner serving a 15-year sentence for manslaughter sought damages under § 1983 against state prosecutors and an investigator for alleged misconduct similar to that alleged here, including knowingly destroying exculpatory evidence and causing an illegal voice identification procedure to be employed at the prisoner's trial.
Emphasizing the concerns with parallel litigation and conflicting judgments just discussed, see
This case differs from Heck because the plaintiff in Heck had been convicted, while McDonough was acquitted. Although some claims do fall outside Heck 's ambit when a conviction is merely "anticipated," Wallace ,
C
The soundness of this conclusion is reinforced by the consequences that would follow from the Second Circuit's approach, which would impose a ticking limitations clock on criminal defendants as soon as they become aware that fabricated evidence has been used against them. Such a rule would create practical problems in jurisdictions where prosecutions regularly last nearly as long as-or even longer than-the relevant civil limitations period. See Brief for Petitioner 53-55; Brief for Criminal Defense Organizations et al. as Amici Curiae 23-24. A significant number of criminal defendants could face an untenable choice between (1) letting their claims expire and (2) filing a civil suit against the very person who is in the midst of prosecuting them. The first option is obviously undesirable, but from a criminal defendant's perspective the latter course, too, is fraught with peril: He risks tipping his hand as to his defense strategy, undermining his privilege against self-incrimination, and taking on discovery obligations not required in the criminal context. See SEC v. Dresser Industries, Inc. ,
Smith suggests that stays and ad hoc abstention are sufficient to avoid the problems of two-track litigation. Such workarounds are indeed available when claims falling outside Heck 's scope nevertheless are initiated while a state criminal proceeding is pending, see Wallace ,
In deferring rather than inviting such suits, we adhere to familiar principles. The proper approach in our federal system generally is for a criminal defendant who believes that the criminal proceedings against him rest on knowingly fabricated evidence to defend himself at trial and, if necessary, then to attack any resulting conviction through collateral review proceedings. McDonough therefore had a complete and present cause of action for the loss of his liberty only once the criminal proceedings against him terminated in his favor.
III
Smith's counterarguments do not sway the result.
First, Smith argues that Heck is irrelevant to McDonough's claim, relying on this Court's opinion in Wallace . Wallace held that the limitations period begins to run on a § 1983 claim alleging an unlawful arrest under the Fourth Amendment as soon as the arrestee "becomes detained pursuant to legal process," not when he is ultimately released.
Smith is correct that Heck concerned a plaintiff serving a sentence for a still-valid conviction and that Wallace distinguished Heck on that basis, but Wallace did not displace the principles in Heck that resolve this case. A false-arrest claim, Wallace explained, has a life independent of an ongoing trial or putative future conviction-it attacks the arrest only to the extent it was without legal process, even if legal process later commences. See
Second, Smith notes (1) that a fabricated-evidence claim in the Second Circuit (unlike a malicious prosecution claim) can exist even if there is probable cause and (2) that McDonough was acquitted. In other words, McDonough theoretically could have been prosecuted without the fabricated evidence, and he was not convicted even *2160with it. Because a violation thus could exist no matter its effect on the outcome, Smith reasons, "the date on which that outcome occurred is irrelevant." Brief for Respondent 26.
Smith is correct in one sense. One could imagine a fabricated-evidence claim that does not allege that the violation's consequence was a liberty deprivation occasioned by the criminal proceedings themselves. See n. 2, supra . To be sure, the argument for adopting a favorable-termination requirement would be weaker in that context. That is not, however, the nature of McDonough's claim.
As already explained, McDonough's claim remains most analogous to a claim of common-law malicious prosecution, even if the two are not identical. See supra , at 2156 - 2157. Heck explains why favorable termination is both relevant and required for a claim analogous to malicious prosecution that would impugn a conviction, and that rationale extends to an ongoing prosecution as well: The alternative would impermissibly risk parallel litigation and conflicting judgments. See supra, at 2156 - 2157. If the date of the favorable termination was relevant in Heck , it is relevant here.
It does not change the result, meanwhile, that McDonough suffered harm prior to his acquittal. The Court has never suggested that the date on which a constitutional injury first occurs is the only date from which a limitations period may run. Cf. Wallace ,
Third and finally, Smith argues that the advantages of his rule outweigh its disadvantages as a matter of policy. In his view, the Second Circuit's approach would provide more predictable guidance, while the favorable-termination approach fosters perverse incentives for prosecutors (who may become reluctant to offer favorable resolutions) and risks foreclosing meritorious claims (for example, where an outcome is not clearly "favorable"). These arguments are unconvincing. We agree that clear accrual rules are valuable but fail to see how assessing when proceedings terminated favorably will be, on balance, more burdensome than assessing when a criminal defendant "learned that the evidence was false and was used against him" and deprived him of liberty as a result.
IV
The statute of limitations for McDonough's § 1983 claim alleging that he was prosecuted using fabricated evidence began to run when the criminal proceedings against him terminated in his favor-that is, when he was acquitted at the end of his second trial. The judgment of the United States Court of Appeals for the Second Circuit is therefore reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered .
Justice THOMAS, with whom Justice KAGAN and Justice GORSUCH join, dissenting.
We granted certiorari to decide when "the statute of limitations for a Section 1983 claim based on fabrication of evidence in criminal proceedings begins to run." Pet. for Cert. i. McDonough, however, declined to take a definitive position on the "threshold inquiry in a [ 42 U.S.C.] § 1983 suit": " 'identify[ing] the specific constitutional right' at issue." Manuel v. Joliet , 580 U. S. ----, ----,
McDonough's failure to specify which constitutional right the respondent allegedly violated profoundly complicates our inquiry. McDonough argues that malicious prosecution is the common-law tort most analogous to his fabrication-of-evidence claim. But without " 'identify[ing] the specific constitutional right' at issue," we cannot adhere to the contours of that right when "applying, selecting among, or adjusting common-law approaches."
McDonough also urges us to resolve the question presented by extending Preiser v. Rodriguez ,
Further complicating this case, McDonough raised a malicious-prosecution claim alongside his fabrication-of-evidence claim. The District Court dismissed that claim on grounds of absolute immunity. McDonough has not fully explained the difference between that claim and his fabrication claim, which he insists is both analogous to the common-law tort of malicious prosecution and distinct from his dismissed malicious-prosecution claim. See Tr. of Oral Arg. 11-12; Reply Brief 3-4. Additionally, it appears that McDonough's fabrication claim could face dismissal on absolute-immunity grounds on remand. Brief for United States as Amicus Curiae 29-32.
The Court, while recognizing that it is critical to ascertain the basis for a § 1983 claim when deciding how to "handl[e]" it, ante, at 2155, n. 2, attempts to evade these issues by "assum[ing] without deciding that the Second Circuit's articulations of the right at issue and its contours are sound." Ante , at 2155. But because the parties have not accepted the Second Circuit's view that the claim sounds in procedural due process,
* * *
McDonough asks the Court to bypass the antecedent question of the nature and elements of his claim and first determine its statute of limitations. We should have declined the invitation and dismissed the writ of certiorari as improvidently granted. I therefore respectfully dissent.
See Floyd v. Attorney General of Pa. ,
In accepting the Court of Appeals' treatment of McDonough's claim as one sounding in denial of due process, we express no view as to what other constitutional provisions (if any) might provide safeguards against the creation or use of fabricated evidence enforceable through a
The Second Circuit borrowed the common-law elements of malicious prosecution to govern McDonough's distinct constitutional malicious prosecution claim, which is not before us. See
Though McDonough was not incarcerated pending trial, he was subject to restrictions on his ability to travel and other " 'restraints not shared by the public generally,' " Justices of Boston Municipal Court v. Lydon ,
Smith urges the Court to steer away from the comparison to malicious prosecution, noting that the Second Circuit treats malicious prosecution claims and fabricated-evidence claims as distinct. See id ., at 268, and n. 12. But two constitutional claims may differ yet still both resemble malicious prosecution more than any other common-law tort; comparing constitutional and common-law torts is not a one-to-one matching exercise. See, e.g. , Heck ,
Such considerations are why Congress has determined that a petition for writ of habeas corpus, not a § 1983 action, "is the appropriate remedy for state prisoners attacking the validity of the fact or length of their confinement," Preiser v. Rodriguez ,
Because McDonough was not free to sue prior to his acquittal, we need not reach his alternative argument that his claim was timely because it alleged a continuing violation.
Heck itself suggested that a similar rule might allow at least some Fourth Amendment unlawful-search claims to proceed without a favorable termination. See
As for Smith's suggestion that the fabricated evidence could not have caused any liberty deprivation where, as here, there could have been probable cause and there was in fact an acquittal, it suffices to reiterate that we assume the contours of the claim as defined by the Second Circuit, see supra, at 2155 - 2156, 2156 - 2157, and nn. 2, 4, and thus accept its undisputed conclusion that there was a sufficient liberty deprivation here, see
Because McDonough's acquittal was unquestionably a favorable termination, we have no occasion to address the broader range of ways a criminal prosecution (as opposed to a conviction) might end favorably to the accused. Cf. Heck ,
