Defendants appeal from an order of the Appellate Division reinstating an indictment against them following that court’s reversal of an order granting their motions to suppress. The suppressed evidence consisted of recorded conversátions
Defendants had been indicted for conspiracy to commit murder and for possession of revolvers. Defendants’ conversations had been overheard and recorded by electronic devices. The conversations revealed a plot to murder witnesses against the defendants (who have been identified as associated with organized crime) in a larceny investigation including the obtaining of suitable weapons sufficient to “ blow big holes in stoolies ” with especially deadly “dum dum” bullets. The electronic devices had been installed as a part of the larceny investigation by the police after obtaining a éourt order under a statute of a kind that for many years had been sustained as valid in the State courts and had never been struck down by the Supreme Court. The police, therefore, were acting in good faith under a statute believed valid by many.
Of course, the statute now having been held invalid, as violative of the Fourth Amendment of the Federal Constitution, it is as if there had never been any valid authority for the police to act as they did. However, it is not the Fourth Amendment which excludes expressly evidence obtained illegally but decisional rules developed by the courts and applied to the States under the holding in Mapp v. Ohio (367 U. S. 643, 648, 650-653, 657-660, supra). These were adopted as a necessary corollary to deter police officials from deliberately violating constitutional rights in order to further their prosecutorial ends with practical impunity. With this policy of deterrence there may no longer
Accordingly, the order of the Appellate Division must be reversed, the motion to suppress granted, and the indictment dismissed.
