Chiaverini v. City of Napoleon
Headline: Ruling says probable cause for one charge does not automatically block malicious‑prosecution claims about a baseless co‑charge, allowing detained people to challenge unlawful holds even when other charges appeared supported.
Holding: The Court held that having probable cause for one charge does not automatically bar a Fourth Amendment malicious‑prosecution claim about a different baseless charge, and it vacated and remanded for the lower court to decide causation.
- Lets detained people challenge baseless charges even when other charges existed.
- Requires lower courts to decide how an invalid charge caused a detention.
- Could lead to more lawsuits against officers over mixed‑charge arrests.
Summary
Background
A jewelry store owner in Napoleon, Ohio, bought a ring for $45 that turned out to be stolen. After the owners demanded the ring back and a series of exchanges with police, officers charged him with three crimes: two misdemeanors (receiving stolen property and dealing in precious metals without a license) and a felony (money laundering). A judge issued a warrant, he was arrested and held three days, and county prosecutors later dropped the case because they failed to present it to a grand jury in time. The owner then sued the officers under federal law, saying the felony charge lacked probable cause and caused an unreasonable seizure.
Reasoning
The Court addressed whether the existence of probable cause for one charge automatically defeats a Fourth Amendment malicious‑prosecution claim about a different, baseless charge. The Justices held that it does not. Under the Fourth Amendment, a detention must be based on probable cause, and an invalid charge can cause a detention to start or continue. The Court also relied on historical common‑law practice, which evaluated probable cause charge by charge rather than treating a valid count as an absolute bar to all claims. The opinion rejected the Sixth Circuit’s categorical rule and vacated that court’s judgment. The Court left for the lower court the harder question of how to prove that a specific baseless charge caused the seizure when valid charges were also present.
Real world impact
The ruling makes clear that people who were arrested and held can potentially sue over baseless charges even if prosecutors or police also had good reasons to bring other counts. It sends the case back to the appeals court to decide the proper test for causation, so the outcome is not yet final and will depend on further proceedings.
Dissents or concurrances
Two separate dissents argued against treating malicious prosecution as a Fourth Amendment claim: one said the claim better belongs under the Fourteenth Amendment’s due process guarantees, and another urged restraint against creating new federal torts.
