good faith exception
good-faith exception. Criminal procedure. An exception to the exclusionary rule whereby evidence obtained under a warrant later found to be invalid (esp. because it is not supported by probable cause) is nonetheless admissible if the police reasonably relied on the notion that the warrant was valid. • The good-faith exception was adopted by the Supreme Court in United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405 (1984). [Cases: Criminal Law 394.4(6). C.J.S. Criminal Law §§ 782–785.]
