Chiaverini v. City of Napoleon Revisions: 6/20/24

Background

Jascha Chiaverini, a jewelry store owner, was arrested after police in Napoleon, Ohio, charged him with three crimes: two misdemeanors (receiving stolen property and dealing in precious metals without a license) and one felony (money laundering). The officers sought an arrest warrant based mainly on an affidavit supporting the felony by claiming Chiaverini suspected the ring was stolen; a judge issued the warrant and Chiaverini was held for three days. County prosecutors later dismissed the charges because they missed a grand‑jury deadline. Chiaverini then sued the officers under a federal law, claiming his arrest and detention were unreasonable because at least one charge lacked probable cause.

Reasoning

The central question was whether a valid charge in a case automatically prevents a Fourth Amendment malicious‑prosecution claim about a different, baseless charge. The Court said no. It explained that the Fourth Amendment requires probable cause for pretrial detention and that an invalid charge can cause a detention to start or continue even when joined with a valid charge. The Court also relied on historical common‑law practice that assessed probable cause charge by charge. The Supreme Court vacated the Sixth Circuit’s ruling and sent the case back for the lower court to decide how to show that a baseless charge actually caused the seizure.

Real world impact

This ruling means judges must consider each criminal charge separately when a person sues over an arrest and detention. People held on multiple charges may be able to challenge a specific unsupported charge that helped start or prolong their detention. Because the Court left open how to prove that an invalid charge caused the seizure, lower courts will now figure out the proper causation test on remand.

Dissents or concurrances

Two separate dissents disagreed. One Justice argued malicious‑prosecution claims do not belong under the Fourth Amendment. Another Justice said such claims concern procedural fairness and fit better under the Fourteenth Amendment or state law.
