procedure followed below is in accordance with “statutory procedures now provided with respect to claims of illegal electronic surveillance in proceedings occurring after October 15, 1970 . . . From now on, the United States will not even review its files to determine the existence of evidence stemming from electronic surveillance unless the defendant meets the “burden of raising any issue of illegal electronic surveillance . . .
The Omnibus Crime Control and Safe Streets Act of 1968, § 802, 82 Stat. 212, 18 U. S. C. §§ 2510-2520 (1964 ed., Supp. Y), provides for electronic surveillance either on warrants issued by a magistrate, § 2516, or on the sole initiative of the designee of the Attorney General who “reasonably determines” that there is “an emergency situation” respecting “conspiratorial activities” which threaten the national security or which involve “organized crime.” §2518(7). The officer must apply for an order approving the interception within 48 hours, complying with procedures for obtaining an order of authorization. If the application is denied, or approval is not issued before the interception is terminated, the contents of any intercepted communication are to be treated as illegally obtained. §2518(7).
The Act sanctions free use of intercepted information among investigative personnel, § 2517 (1). It also widely protects “evidence derived therefrom,” §§2517 (1), (2), and (3), including the giving of testimonial evidence.6 But any person whose “wire or oral communication is intercepted, disclosed, or used” in violation of the ways I have enumerated has suit for actual and punitive damages and reasonable attorneys’ fees and costs. § 2520.

There is the initial question whether any intercepted communications relating to the offense of which petitioner was convicted are evidence of “offenses other than those specified in the order of authorization or approval,” §2517 (5). If so, “[s]uch contents and any evidence derived therefrom may be used [as testimony at trial] *999when authorized or approved by a judge of competent jurisdiction where such judge finds on subsequent application that the contents were otherwise intercepted in accordance with the provisions of this chapter.” This would seem to place upon the Government the burden of knowing the source of its evidence, even without challenge from a defendant.
