What is the Exclusionary Rule?

• A. Any evidence obtained with warrants is admissible.
• B. Evidence obtained in violation of the Fourth Amendment cannot be used in court.
• C. Hearsay evidence is always excluded.
• D. The rule prohibits double jeopardy.

Answer: (B)

The Exclusionary Rule says that evidence obtained in violation of the Fourth Amendment’s protection against unreasonable searches and seizures cannot be used against a defendant in court. This means if police conduct an illegal search or seizure—like searching without probable cause or beyond the scope of a warrant—the items or statements gathered as a result are typically not admissible to prove guilt. The idea is to deter illegal police conduct and to preserve Fourth Amendment rights. There are narrowly defined exceptions (such as the good-faith exception, or independent source/inevitable discovery doctrines) where some tainted evidence might still be admitted, but those are limited and do not guarantee admissibility in every case. The other options don’t fit because the Exclusionary Rule is not about warrants guaranteeing admissibility, nor does it govern hearsay rules or double jeopardy. A warrant does not automatically ensure admissibility if the search itself was unlawful or improperly executed. Hearsay concerns separate declarations offered for truth of the matter asserted and are governed by separate rules of evidence. Double jeopardy protects against being tried twice for the same offense, a principle arising under the Fifth Amendment, not the Exclusionary Rule.
