Chiaverini v. City of Napoleon
The Supreme Court ruled that police officers cannot escape a civil rights lawsuit over a baseless charge just because they also filed other legitimate charges in the same case.
The decision resolves a split among federal appeals courts and requires courts to evaluate each charge on its own merits when a person claims they were wrongfully arrested or detained.
“The answer is no: The valid charges do not create a categorical bar. We leave for another day the follow-on question of how to determine in those circumstances whether the baseless charge caused the requisite seizure.”
The majority's core holding that a valid charge does not automatically block a lawsuit over a baseless one.
How it got here: The district court granted summary judgment to the officers; the Sixth Circuit affirmed on the ground that probable cause for the misdemeanor charges ended the inquiry; the Supreme Court agreed to hear the case to resolve a split among federal appeals courts.
The Case in Depth
What happened
Jascha Chiaverini, a jewelry store owner in Napoleon, Ohio, was charged by police with two misdemeanors and a felony money-laundering charge after a dispute over a ring he had purchased from a thief. Officers obtained a warrant, arrested him, and held him for three days. County prosecutors later let the case lapse without presenting it to a grand jury. Chiaverini sued the officers, arguing the felony charge was fabricated and lacked any legitimate basis.
The question before the Court
When police file multiple charges and only one of them lacks probable cause, can someone sue officers for a wrongful prosecution based solely on the unsupported charge?
The Court's answer
Yes — a valid charge does not automatically block a civil rights lawsuit over a baseless charge filed in the same criminal case. The Court ruled that courts must evaluate each charge on its own: if an unsupported charge caused a person to be arrested or kept in jail — even alongside a legitimate charge — that can be a constitutional violation. Both Fourth Amendment doctrine and historical common-law practice reach the same conclusion. Under Fourth Amendment rules, any pretrial detention must be based on probable cause, and a detention extended by a fabricated charge is unreasonable even if another valid charge exists. At common law, plaintiffs could sue over any baseless charge in a prosecution, regardless of whether other charges were well founded.
The Court did not decide the next key question: how a plaintiff proves that the baseless charge actually caused the arrest or detention when valid charges were filed at the same time. Three different approaches were proposed by the parties, but the Court returned that causation question to the lower court to address first.

Why it matters
People who are arrested or jailed on a mix of legitimate and fabricated charges can now pursue civil rights lawsuits specifically targeting the unsupported charge, even if other charges were valid. This matters most for people who were held longer — or under harsher conditions — because of a baseless charge bundled alongside solid ones. Officers can no longer use a valid charge as an automatic shield against claims about the bad one.
What changes now
The case returns to the Sixth Circuit, which must now decide the causation question the Supreme Court left open: when both valid and baseless charges are filed together, how does a plaintiff prove that the unsupported charge actually caused the arrest or detention? Three different legal tests were proposed — a "taint" approach, a but-for test, and a stricter legal-authorization test — and the lower court must choose and apply one. Only after that determination will it be clear whether Chiaverini's lawsuit can ultimately proceed.
What this does not decide
The Court did not decide how a plaintiff must prove that a baseless charge actually caused an arrest or detention when the officers also filed valid charges at the same time. That causation question — contested under at least three different proposed legal tests — is expressly left for the lower court to resolve on remand.
Concurrences and dissents
Dissent — Justice Thomas
Justice Thomas, joined by Justice Alito, argued that the entire framework of Fourth Amendment malicious-prosecution claims is mistaken and should be abandoned. In his view, malicious prosecution and Fourth Amendment unreasonable seizure are fundamentally different legal concepts — one turns on malicious intent and prosecution outcomes; the other is objective and can arise without any prosecution at all. Because the Court's earlier decision recognizing such claims was wrong, he would have affirmed the dismissal of Chiaverini's suit outright rather than sending it back for further proceedings.
Dissent — Justice Gorsuch
Justice Gorsuch dissented separately, agreeing that grafting malicious prosecution onto the Fourth Amendment creates an ill-fitting hybrid tort but going further to suggest a different constitutional home: the Fourteenth Amendment's due process guarantee, which actually focuses on judicial proceedings, would better fit claims about the abuse of criminal process. He also noted that many states — including Ohio — already offer their own malicious-prosecution tort that may be easier to prove and does not require a plaintiff to show they were seized.
How the Court got there
The legal reasoning, step by step
- The Court began with established Fourth Amendment doctrine: any pretrial detention must be based on probable cause, and a detention that starts or continues on the basis of an invalid charge is an unreasonable seizure — a constitutional violation — even if a separate valid charge was also filed alongside it.
- Building on Rodriguez v. United States (a 2015 case holding that even a lawful detention can become unconstitutional if it is unreasonably prolonged), the Court reasoned that a baseless charge that extends a person's time in custody independently violates the Fourth Amendment, regardless of whether another charge was legitimate.
- The Court then looked to the common-law tort of malicious prosecution, which §1983 civil rights lawsuits are modeled on. Nineteenth-century courts uniformly held that a plaintiff could sue over any baseless charge even when other charges in the same case had proper legal support — probable cause was assessed charge by charge, not case by case.
- Both legal frameworks — Fourth Amendment doctrine and common-law malicious prosecution — therefore pointed the same direction: a single valid charge in a criminal proceeding does not categorically immunize officers from a civil rights claim based on a different, baseless charge. The Sixth Circuit's blanket rule to the contrary was incorrect.
- The Court stopped short of resolving the follow-on causation question — how a plaintiff demonstrates that the baseless charge actually caused the arrest or detention when valid charges were also present. Three competing tests were proposed by the parties and the government, but because the lower court had never addressed the issue, the Court sent the case back for that analysis to be done first.
