Number: RS22475 Title: Hudson v. Michigan: The Exclusionary Rule's Applicability to "Knock-an-Announce" Violations Authors: Alison M. Smith, American Law Division Abstract: Since the 1980s, the United States Supreme Court has issued a series of decisions narrowing the applicability of the exclusionary rule. As such, the exclusionary rule is inapplicable in civil cases, grand jury proceedings, and parole revocation hearings. Other exceptions to the exclusionary rule include inevitable or independent discovery, attenuation, and the good-faith exception. In Hudson v. Michigan,126 S.Ct. 2159 (2006), the Court further narrowed the applicability of the exclusionary rule by finding that the rule was not an appropriate remedy when police officers fail to wait a few seconds after they knock and announce their presence while executing a valid search warrant.
