Sometimes judiciaries make errors when issuing warrants—they may not have had adequate probable cause to do so. Or, the information trusted upon by the police may turn out to be wrong, through no fault of the police. In most circumstances, the search will still be valid. In the case of U.S. v. Leon (1984), the U.S. Supreme Court administrated that if the police conduct a search in good faith reliance on a warrant, the search is valid and the evidence is admissible, even if the warrant was in fact void through no fault of the police.  If the police had judicious, good faith belief that they were performing according to legal authority, such as by depending on a search warrant that is later found to have been legally unreliable, the illegally seized evidence is admissible under this rule.
