Elijah Manuel was arrested and charged with possessing unlawful drugs. A judge decided that he would be held in jail pending trial. Forty-seven days later the prosecutor dismissed all charges after concluding that the pills Manuel had been carrying were legal. The next day he was released. Last year the Supreme Court held that Manuel is entitled to seek damages on the ground that detention without probable cause violates the Fourth Amendment (applied to the states by the Fourteenth). Manuel v. Joliet , --- U.S. ----, 137 S.Ct. 911 , 197 L.Ed.2d 312 (2017). The Justices remanded the question whether Manuel sued in time. Id . at 920-22. The parties agree that Illinois law, which supplies the period of limitations under Wilson v. Garcia , 471 U.S. 261 , 105 S.Ct. 1938 , 85 L.Ed.2d 254 (1985), gave Manuel two years from the claim's accrual. But federal law defines when a claim accrues. Wallace v. Kato , 549 U.S. 384 , 388, 127 S.Ct. 1091 , 166 L.Ed.2d 973 (2007).

Here are the potentially important dates:

• March 18, 2011: Manuel is arrested

• March 18, 2011: A judge orders Manuel to remain in custody for trial

• May 4, 2011: The prosecutor dismisses the charge

• May 5, 2011: Manuel is released

• April 22, 2013: Manuel sues under 42 U.S.C. § 1983

Defendants contend that Manuel's claim accrued on March 18, when the judge ordered him held pending trial. If that's right, then Manuel sued too late. He maintains that the clock started on May 4, when his position was vindicated by dismissal of the prosecution. We do not accept either approach. We hold that Manuel's claim accrued on May 5, when he was released from custody. That makes this suit timely.

Defendants' position relies on Wallace , which held that a Fourth Amendment claim accrues (and the period of limitations starts) as soon as the plaintiff has been brought before a judge (or, in the language of both Wallace and Manuel , has been held pursuant to legal process). 549 U.S. at 389-91 , 127 S.Ct. 1091 . This position encounters two problems.

First, Wallace complained about his arrest rather than the custody that post-dated his appearance before a judge. Wallace , 549 U.S. at 386-87 , 127 S.Ct. 1091 . Many violations of the Fourth Amendment concern pre-custody events: a search may invade privacy without the authorization of a warrant, or the police may use excessive force. These events can be litigated without awaiting vindication on the criminal charges, Wallace holds, because they do not deny the validity of any ensuing custody. Id . at 389-90, 127 S.Ct. 1091 . Manuel, by contrast, contests the propriety of his time in custody.

Second, the line that the Justices drew in Wallace -in which a claim accrues no later than the moment a person is bound over by a magistrate or arraigned on charges, see 549 U.S. at 389 , 127 S.Ct. 1091 , and all Fourth Amendment claims are to be treated alike-did not survive Manuel . There the Court held that wrongful pretrial custody violates the Fourth Amendment "not only when it precedes, but also when it follows, the start of legal process in a criminal case." 137 S.Ct. at 918 . When a wrong is ongoing rather than discrete, the period of limitations does not commence until the wrong ends. See, e.g., National Railroad Passenger Corp. v. Morgan , 536 U.S. 101 , 115-21, 122 S.Ct. 2061 , 153 L.Ed.2d 106 (2002). Notice that we speak of a continuing wrong , not of continuing harm ; once the wrong ends, the claim accrues even if that wrong has caused a lingering injury. See United States v. Kubrick , 444 U.S. 111 , 100 S.Ct. 352 , 62 L.Ed.2d 259 (1979) ; Delaware State College v. Ricks , 449 U.S. 250 , 101 S.Ct. 498 , 66 L.Ed.2d 431 (1980) ; Turley v. Rednour , 729 F.3d 645 , 654-55 (7th Cir. 2013) (concurring opinion). Manuel shows that the wrong of detention without probable cause continues for the length of the unjustified detention. When a search or seizure causes injury independent of time spent in custody, the claim accrues immediately; but when the objection is to the custody, a different approach must control.

Manuel's position, which relies on an analogy to the tort of malicious prosecution-in which the claim does not accrue until the plaintiff has prevailed ("been vindicated") in the criminal case-might have seemed sensible before the Supreme Court spoke. As the Supreme Court recounted, it was popular among other courts of appeals, which characterized the claim as "Fourth Amendment malicious prosecution." Manuel , 137 S.Ct. at 921 . If that's the claim, then what could be better than a rule devised for malicious-prosecution suits? Indeed, the defendants themselves conceded when this case was last here that, if the wrong is (as Manuel insisted) "Fourth Amendment malicious prosecution," then the accrual date is May 4. But the Justices deprecated the analogy to malicious prosecution.

After Manuel , "Fourth Amendment malicious prosecution" is the wrong characterization. There is only a Fourth Amendment claim-the absence of probable cause that would justify the detention. 137 S.Ct. at 917-20 . The problem is the wrongful custody. "[T]here is no such thing as a constitutional right not to be prosecuted without probable cause." Serino v. Hensley , 735 F.3d 588 , 593 (7th Cir. 2013). But there is a constitutional right not to be held in custody without probable cause. Because the wrong is the detention rather than the existence of criminal charges, the period of limitations also should depend on the dates of the detention.

The wrong of detention without probable cause continues for the duration of the detention. That's the principal reason why the claim accrues when the detention ends. (The parties have debated whether a need to prove malice affects the claim's accrual. But after the Supreme Court's decision this is a plain-vanilla Fourth Amendment claim, and analysis under that provision is objective. See, e.g., Ashcroft v. al-Kidd , 563 U.S. 731 , 131 S.Ct. 2074 , 179 L.Ed.2d 1149 (2011).)

A further consideration supports our conclusion that the end of detention starts the period of limitations: a claim cannot accrue until the would-be plaintiff is entitled to sue, yet the existence of detention forbids a suit for damages contesting that detention's validity.

Preiser v. Rodriguez , 411 U.S. 475 , 93 S.Ct. 1827 , 36 L.Ed.2d 439 (1973), holds that the right way to contest ongoing state custody is by a petition for a writ of habeas corpus under 28 U.S.C. § 2241 or § 2254, not by an action under § 1983 seeking an injunction requiring release. Heck v. Humphrey , 512 U.S. 477 , 114 S.Ct. 2364 , 129 L.Ed.2d 383 (1994), adds that § 1983 cannot be used to obtain damages for custody based on a criminal conviction-not until the conviction has been set aside by the judiciary or an executive pardon. Although Heck dealt exclusively with § 1983 proceedings that imply the invalidity of a conviction, Edwards v. Balisok , 520 U.S. 641 , 117 S.Ct. 1584 , 137 L.Ed.2d 906 (1997), extended its approach to custody that rests on the decision of a prison's administrative panel revoking some of a prisoner's good-time credits.

After Preiser , Heck , and Edwards , § 1983 cannot be used to contest ongoing custody that has been properly authorized. Those decisions do not concern the way to deal with executive custody that lacks a judicial imprimatur-for example, detention in a police department's cells before presentation to a judge. But Manuel was held by authority of a judicial decision that probable cause existed to show that he had committed a drug offense. He contends that the police hoodwinked the judge by falsely asserting that the pills he possessed had tested positive for an unlawful drug, and if he is right he is entitled to damages. Still, his detention was judicially authorized, which given Preiser means that a § 1983 suit had to wait until his release. Heck tells us that a claim does not accrue before it is possible to sue on it. 512 U.S. at 489-90 , 114 S.Ct. 2364 . Once he was out of custody and could sue, Manuel's claim accrued. He filed this action within two years and is therefore entitled to a decision on the merits.

The judgment of the district court is reversed, and the case is remanded for proceedings consistent with this opinion and the Supreme Court's.
