with whom The Chief Justice joins, dissenting.
It is my opinion that certiorari should be granted and the case remanded for a hearing in the District Court with *1020respect to the electronic surveillance which the Solicitor General has revealed to us. According to the Solicitor General, agents of the Federal Bureau of Investigation on or about May 11, 1962, surreptitiously and by trespass installed an electronic listening device in a “commercial establishment' in Florida owned by an acquaintance of petitioner Levine and in which Levine may have had a proprietary interest.” The device was in operation for .nearly one year. During that time a number of conversations in which Levine participated were overheard. Some of those conversations were between Levine and attorneys representing him in prosecutions for interstate transport of counterfeit securities and for stock and mail fraud, matters then pending in a federal court in Florida.
The Solicitor General represents that this violation of petitioner Levine’s constitutional rights had no connection with the present case, which involves a prosecution in New York for failure to file income tax returns for 1956 and 1957. He says that it originated in connection with an FBI investigation relating to the charges for which petitioner Levine was tried and convicted in Florida. See Rogers v. United States, 334 F. 2d 83 (C. A. 5th Cir.), cert. denied, sub nom. Levine v. United States, 380 U. S. 915; Gradsky v. United States, 342 F. 2d 147 (C. A. 5th Cir.), vacated and remanded sub nom. Levine v. United States, 383 U. S. 265. The Government represents that nothing was overheard which had anything to do with the present criminal tax case, and that neither the Internal Revenue Service nor prosecuting counsel was apprised of the existence of the surveillance. The Solicitor General says that petitioner Levine will be furnished with the logs so that he may take whatever action is appropriate in the District. Court in Florida relating to the convictions obtained in that court.
It is entirely possible, perhaps even probable, that the Solicitor General’s representations will be validated, and *1021it may be that ño reason will be developed for invalidating the present convictions because of the trespassory espionage or its fruits. But this is “dirty business.” Olmstead v. United States, 277 U. S. 438, 470 (1928) (dissenting opinion of Mr. Justice Holmes). It is important enough for the Solicitor General to call to our attention. And an. appraisal of the material and the circumstances by defense counsel may adduce facts affecting the weight to be given the unlawful operation which would never occur to the prosecutor. The prosecutorial eye is, after all, apt to yield an out-of-focus picture, as is the eye of the defense. But in our system we insist upon the perspective developed by both. See Dennis v. United States, 384 U. S. 855, 875 (1966). In.any event, the facts, circumstances, yield, and fruits of the electronic surveillance should be exposed in the record of this case so that wé may, at least, be sure that the Government’s trespas-sory surveillance has not infected the trial of these petitioners.
