Case Brief Summary & Legal Analysis
tl;dr: The Supreme Court held that the Fourth Amendment’s exclusionary rule, which bars illegally obtained evidence in criminal trials, does not apply in civil deportation proceedings. The Court reasoned that the rule’s deterrent benefits are outweighed by the significant social costs of ignoring an ongoing immigration violation.
Legal Significance: This case significantly limits the scope of the Fourth Amendment’s exclusionary rule, establishing that it does not apply in civil deportation hearings. It solidifies the use of a cost-benefit balancing test to determine the rule’s applicability outside of core criminal prosecutions.

Case Facts & Court Holding
Key Facts & Case Background
Respondents Lopez-Mendoza and Sandoval-Sanchez, both Mexican citizens, were arrested by Immigration and Naturalization Service (INS) agents at their respective workplaces. The agents lacked warrants for the arrests. Following their arrests, both respondents made statements admitting their illegal status in the United States. In separate civil deportation hearings, the government introduced these admissions as evidence of deportability. Sandoval-Sanchez moved to suppress his statements, arguing they were the fruit of an unlawful arrest that violated the Fourth Amendment. Lopez-Mendoza challenged the proceeding itself based on his allegedly illegal arrest. In both cases, the Immigration Judge and the Board of Immigration Appeals (BIA) held that the legality of the arrests was irrelevant in a civil deportation proceeding and refused to apply the exclusionary rule. The Court of Appeals for the Ninth Circuit reversed, holding that the exclusionary rule was applicable. The Supreme Court granted certiorari.
