What is the exclusionary rule?

• A. The rule allows evidence obtained illegally if the police acted in good faith.
• B. The rule requires all evidence to be admitted regardless of how it was obtained.
• C. The exclusionary rule prevents the use of evidence obtained in violation of the Fourth Amendment in court.
• D. It applies only to federal cases.

Answer: (C)

The exclusionary rule is a constitutional safeguard that bars the use of evidence obtained through illegal searches or seizures. When police violate the Fourth Amendment, the court generally suppresses that evidence so it cannot be used to prove guilt at trial. This remedy protects constitutional rights and discourages unlawful police conduct. There are related ideas, like the good-faith exception, which allows evidence to be admitted if officers reasonably relied on a defective warrant; that distinction helps explain why evidence isn’t simply allowed in all cases. Also, the protection isn’t limited to federal courts—it applies to state courts as well through incorporation, so it covers both federal and state actions.
