What is exclusionary rule?

  • (noun): A rule that provides that otherwise admissible evidence cannot be used in a criminal trial if it was the result of illegal police conduct.

Exclusionary Rule

The exclusionary rule is a legal principle in the United States, under constitutional law, which holds that evidence collected or analyzed in violation of the defendant's constitutional rights is sometimes inadmissible for a criminal prosecution in a court of law. This may be considered an example of a prophylactic rule formulated by the judiciary in order to protect a constitutional right. However, in some circumstances at least, the exclusionary rule may also be considered to follow directly from the constitutional language, such as the Fifth Amendment's command that no person "shall be compelled in any criminal case to be a witness against himself" and that no person "shall be deprived of life, liberty or property without due process of law".
