Which case is associated with the Good Faith Exception?

• A. Mapp v Ohio
• B. Katz v United States
• C. Hudson v Michigan
• D. Terry v Ohio

Answer: (C)

The Good Faith Exception to the exclusionary rule allows evidence obtained during a search to be used in court when police acted with honest and reasonable reliance on a warrant that is later found to be defective. This principle was established in United States v. Leon (1984). The Court reasoned that excluding such evidence would punish mistakes by judges or magistrates and not misconduct by the police, so as long as officers believed they were following a valid warrant, the evidence should not be suppressed.

Other cases shown deal with different Fourth Amendment issues, not the good-faith reliance on a warrant: Mapp v. Ohio extended the exclusionary rule to state prosecutions, Katz v. United States recognized a person’s reasonable expectation of privacy in certain contexts, Hudson v. Michigan addressed knock-and-announce and how it affects suppression, and Terry v. Ohio dealt with stop-and-frisk based on reasonable suspicion. The case most closely linked to the Good Faith Exception is United States v. Leon.
