United States v. Calandra
Headline: Grand jury witnesses cannot refuse questions based on evidence from illegal searches; Court blocked that defense, making it easier for prosecutors to use such leads in grand jury investigations.
Holding: The Court ruled that a person summoned before a grand jury may not refuse to answer questions simply because those questions rely on evidence seized in an unlawful search, and the exclusionary rule does not bar grand jury questioning.
- Grand jury witnesses cannot refuse to answer based on illegally seized evidence.
- Makes it easier for prosecutors to question witnesses during grand jury investigations.
- Leaves other remedies, like lawsuits and return of property, available to victims.
Summary
Background
The case involves John Calandra, the owner of a small Cleveland business, whose workplace was searched in December 1970 during a gambling and loansharking probe. Agents spent hours searching his office and seized documents, including a card linking a third party. A special grand jury later subpoenaed Calandra to ask questions based on those seized items. Calandra refused to answer and the district court ordered the seized evidence suppressed and barred grand jury questioning; the Court of Appeals agreed. The Government sought review, and the Supreme Court took the case.
Reasoning
The core question was whether a person summoned before a grand jury can refuse to answer questions because those questions rest on evidence obtained in an unlawful search. The Court emphasized the grand jury’s broad investigatory role and explained that the exclusionary rule is a judicial remedy meant mainly to deter unlawful police searches. Extending that remedy to let witnesses stop grand jury questioning would disrupt investigations, create mini-trials, and add delay. The Court therefore held that questions derived from past illegal searches do not amount to a new Fourth Amendment invasion and that the exclusionary rule does not bar grand jury questioning.
Real world impact
As a result, grand juries may question witnesses based on leads from improperly obtained evidence, and witnesses generally may not refuse on that ground. The opinion notes other remedies still exist for victims (for example, return of property or damages claims), but it removes a ground for blocking grand jury inquiries and speeds investigatory use of seized leads.
