delivered the opinion of the Court.

The petitioner was convicted in a New York trial court in 1966 on three counts of conspiracy to extort, attempted extortion, and coercion. The case for the prosecution rested principally on the content of two telephone conversations between the petitioner and one of his co-conspirators. Tapes and transcripts of those conversations were introduced at the trial over the petitioner’s objection that they had been obtained by an unlawful *281wiretap. The conviction was affirmed by the Appellate Division of the Supreme Court of New York1 and by the New York Court of Appeals.2 We granted certiorari.3

The telephone calls in question were made in 1964 by the petitioner from outside New York City to a co-conspirator at a bar in Manhattan. The conversations were recorded by means of a device attached to wires of the central terminal box in the basement of the building in which the bar was located. This wiretapping was conducted pursuant to a warrant issued under N. Y. Code Crim. Proc. § 813-a, the statute with which this Court subsequently dealt in Berger v. New York, 388 U. S. 41, in reversing a conviction under the Fourth and Fourteenth Amendments.

The petitioner contends that the Fourth and Fourteenth Amendments as construed in Berger, as well as § 605 of the Federal Communications Act,4 prohibited the introduction of the intercepted conversations and therefore require reversal of. his conviction. For the reasons stated below, we reject these contentions and affirm the judgment of the New York Court of Appeals.5

*282Not until last Term in Katz v. United States, 389 U. S. 347, did this Court overrule its prior decisions that the Fourth Amendment encompassed seizures of speech only if the law enforcement officers committed a trespass or at least physically invaded a constitutionally protected area of the speaker.6 Olmstead v. United States, 277 U. S. 438, explicitly held that wiretapping conducted without such an intrusion was not an unlawful search or seizure. That rule was not modified by Berger v. New York. The Court's discussion of Olmstead in Berger, while recognizing that other cases had negated the statements in Olmstead that conversations are never protected by the Fourth Amendment, cast no doubt upon “[t]he basis of the [Olmstead] decision” — “that the Constitution did not forbid the obtaining of evidence by wiretapping unless it involved actual unlawful entry into the house.”7 Furthermore, the Court in Berger found the overbreadth of N. Y. Code Crim. Proc. § 813-a repugnant to the Fourth Amendment only to the limited extent that it permitted a “trespassory intrusion into a constitutionally protected area.” 8

Olmstead, then, stated the controlling interpretation of the Fourth Amendment with respect to wiretapping until it was overruled by Katz. And in Desist v. United States, ante, p. 244, we have held today that Katz is to be applied wholly prospectively. Since the wiretapping in this case occurred before Katz was decided and was accomplished without any intrusion into a constitutionally protected area of the petitioner, its fruits were not inadmissible under the exclusionary rule of the Fourth *283and Fourteenth Amendments. Mapp v. Ohio, 367 U. S. 643.

Nor did § 605 of the Federal Communications Act require exclusion of the intercepted conversations. Until our decision last Term in Lee v. Florida, 392 U. S. 378, state trial courts were free to accept evidence violative of | 605.9 Lee extended the Nardone10 exclusionary rule of § 605 to the States, but that decision has also been held to apply only prospectively. Fuller v. Alaska, 393 U. S. 80. The wiretapping evidence was introduced at the petitioner’s trial in 1966, long before the date of our decision in Lee.

dissenting.

It is conceded that petitioner’s conviction rested largely upon evidence acquired by nontrespassory wiretapping conducted pursuant to a warrant issued under N. Y. Code Crim. Proc. § 813-a. The Court affirms the conviction on the ground that today’s decision in Desist v. United States, ante, p. 244, necessarily dictates that evidence *284obtained by an illegal, nontrespassory wiretap will be inadmissible only if the tapping occurred after the date of the decision in Katz v. United States, 389 U. S. 347 (1967). The wiretapping in this case took place prior to Katz. However, the case is here on direct review, and for the reasons stated in Part I of my dissenting opinion in Desist, supra, at 258-259, I would hold that petitioner is entitled to benefit from the Katz rule.

It is therefore necessary for me to consider whether petitioner’s federal constitutional rights were violated by the wiretapping. Were I free to do so, I would decide this issue by inquiring whether, on the facts of this particular case and in light of New York decisions construing § 813-a, the wiretapping was valid under the Warrants Clause of the Fourth Amendment. See Ker v. California, 374 U. S. 23, 30-34 (1963); see also Mapp v. Ohio, 367 U. S. 643 (1961). However, I believe that this approach is foreclosed by this Court’s decision in Berger v. New York, 388 U. S. 41 (1967). In Berger, the Court held that a “bugging” pursuant to a § 813-a warrant violated the petitioner’s Fourth Amendment rights because on its face the statute did not contain constitutionally required safeguards. It is true that the “bugging” in Berger involved a trespass and that the Court did not reach the question whether Olmstead should be overruled. But the holding that § 813-a was to be considered on its face rather than as applied depended in no way upon the fact of physical intrusion. The warrant procedure prescribed in § 813-a applies equally to “bugging” and to wiretapping. Hence, the Court’s “on its face” approach would seem necessarily to embrace § 813-a wiretapping.

I dissented from the “on its face” approach adopted in Berger. See 388 U. S., at 89 et seq. I continue to disagree with that approach. Yet I think that Berger must be taken as having decided that a warrant issued *285pursuant to the version of § 813-a then in effect could not possibly satisfy the requirements of the Fourth Amendment.* Since I regard myself as bound by Berger, I am reluctantly compelled to conclude that the wiretap evidence introduced against petitioner was seized in violation of the Constitution, and that his conviction consequently cannot stand.
