be distinguished from the present case,19 we conclude that it is our duty to respect it as a viable precedent on the question of standing and to entertain appellant’s challenge.
In a sense, deciding to entertain a facial challenge to a statute such as Title III is more easily said than done. For this statute merely provides safeguards for a procedure which might legitimately be undertaken without any statutory authorization at all. See Katz v. United States, 389 U.S. 347, 354-356, 88 S.Ct. 507, 19 L.Ed.2d 576.20 Presumably, a declaration of facial invalidity would mean that even though the application of the statute in this and in comparable cases is permissible, there is a range of applications permitted by the statute which exceeds constitutional limitations. But what is the appropriate range? What, in other words, is the test for declaring an authorizing statute facially unconstitutional ?
If we were to conclude, as apparently Judge Aldisert does in his careful op in-ion in United States v. Cafero, 473 F.2d 489 (3rd Cir. 1973), that compliance with this statute will make it virtually impossible to violate the Fourth Amendment rights of any citizen, then surely the statute must be upheld. On the other hand, if we should conclude that there is a significant possibility that district judges will from time to time grant overly broad intercept authority without departing from any of the statutory safeguards, does it follow, as Judge Lord reasoned in Whitaker, that the entire statute must fall?21 Or are we to engage in a form of balancing, attempting to weigh the probable number of impermissible applications of the statute against the number of cases in which it will be applied constitutionally, and then express an empirical judgment about its facial validity?
We find none of the above approaches acceptable and suggest, somewhat tentatively, a slightly different formulation.22 Realistically, we think

The Supreme Court in Berger did not explicitly rely upon the strength of petitioner’s own Fourth Amendment claim in permitting challenge to the Xew York statute on its face.

Ordinarily, cases in which facial constitutional adjudication has been considered appropriate have involved criminal statutes, or at least disciplinary sanctions. In such cases, the consequence of a judicial determination of facial unconstitutionality is unambiguous. Similarly, if Congress had no power to authorize the practices described in the legislation, a ruling that the statute is facially invalid would be understandable. See, ,e. g., Schechter Poultry Corp. v. United States, 295 U.S. 495, 550, 55 S.Ct. 837, 79 L.Ed. 1570. But the analysis in Katz makes it clear that this is not such a case. It is therefore difficult to know precisely what a declaration that this statute is facially unconstitutional would mean.

We believe the crux of Judge Lord’s opinion is found in the following passage: “If a judge exercised certain discretionary powers which the Act gives him, the order may not violate the Fourth Amendment. The difficulty, though, is precisely that those powers are discretionary and not mandated. It follows that the Act does not command a constitutional order; it permits an uneonstltu-tional one.” United States v. Whitaker, supra n. 18, 343 F.Supp. at 363.

The majority in Berger did not specifically announce the standard that they employed. The explanation may lie in the fact that the opinion, when announced, was subject to the interpretation that the Court intended to forbid all wiretapping of telephones. In his dissent in Katz v. United States the following Term, Mr. Justice Black observed: 389 U.S. at 364, 88 S.Ct. at 518. See also Kitch, Katz v. United States: The Limits of the Fourth Amendment, 1968 S.Ct.Rev. 133, 143: “In Katz itself the Court proceeded to make clear that, contrary to the implications *531of its decision in Berger v. New York, electronic surveillance under limited conditions could be authorized by a warrant.” (Footnotes omitted.) That such an interpretation of the opinion was reasonable is bolstered by the fact the petitioner specifically argued such a contention to the Supreme Court.
