OPINION OF THE COURT
The primary issue raised by this appeal is whether a citizen who is summoned before a grand jury may object to questions based on information obtained through allegedly illegal and indeed unconstitutional wiretapping directed against the witness. Because of the great importance of what is at stake *200here — not only the interpretation of provisions of the Omnibus Crime Control and Safe Streets Act dealing with unauthorized electronic surveillance, but also the Fourth Amendment — we are constrained to set forth our views in some detail.
We begin with the reminder that the basic purpose of the Fourth Amendment, recognized by countless decisions of the Supreme Court, is to safeguard the privacy and security of citizens against arbitrary invasions by governmental officials. It thus gives concrete expression to a right of the people basic to a free society.1
Sister Joques Egan, a member of the Order of Sacred Heart, was called before a federal grand jury in the early afternoon of January 14th in connection with an investigation into an alleged plot to kidnap a high public official and other offenses. An indictment naming six defendants had been handed down several days before, and it had named Sister Egan as an alleged co-conspirator, but not as a co-defendant.2 Immediately following her refusal to testify on Fifth Amendment grounds, her counsel was served by the Government with an application for immunity pursuant to 18 U.S. C.A. § 6003 of the Organized Crime Control Act of 1970.
The District Court held an immediate hearing on this first immunity application. During the course of the hearing, counsel for appellant argued that the constitutionality of § 6003 was subject to serious doubt, repeatedly asked the Court for sufficient time to prepare and file a brief, and also sought an opportunity to make a motion to suppress. The Government asserted that the validity of § 6003 was assured, and that any delay in granting the application would impede the progress of the grand jury. At the close of argument, the Court allowed counsel until the following day, January 15th, to file additional legal memoranda. The next morning, counsel argued that because the Act of 1970 provided solely for “use,” as distinguished from “transactional,” immunity, it was unconstitutional. The Court adjourned until January 25th. On January 25th, the Court granted the application for immunity under § 6003, and Sister Egan was directed to be available for examination the next morning, January 26th.
Contrary to the Court’s instruction, and in direct reversal of the Government’s announced intention, appellant was not called before the grand jury on January 26th. Instead, the Government served counsel with an application for a grant of “transactional immunity” under 18 U.S.C.A. § 2514, the Omnibus Crime Control and Safe Streets Act of 1968, stating that the Court would hear this new application “immediately.” 3
Appellant’s counsel, having had the new application for only fifteen minutes, asked for adequate time to prepare to argue the applicability and the constitutionality of § 2514 of the 1968 Act. Indeed the undated authorization letter from the Assistant Attorney General was not shown to Sister Egan's counsel until all parties were in the courtroom for the hearing. The Court refused to give defense counsel the opportunity to argue the applicability of § 2514, and instead immediately signed the order granting immunity and requiring Sister Egan to appear before the grand jury forthwith. Sister Egan’s counsel, together with the Government attorney, went to the Court’s chambers and made additional *201objections both to the applicability of § 2514 and the lack of adequate notice and time to prepare argument.4 The Court overruled all the objections made by Sister Egan’s counsel, but did acknowledge the shortness of time permitted counsel to prepare for the hearing.
Before the grand jury once again, Sister Egan refused to testify on several grounds,5 one of which is her primary contention on appeal — that the information which caused the Government to subpoena her and which prompted the questions propounded to her flowed from illegal wiretapping and electronic surveillance.
On January 26, 1971 — minutes after her refusal to testify — appellant was brought back before the Court and, after being instructed to answer the questions and refusing to answer them, was held in contempt. Appellant stated to the Court she was not being disrespectful, but that in addition to the legal grounds already set forth her conscience compelled her not to answer. The Court ordered that she be held in prison until she testified or until the end of the life of the grand jury.
Thereafter, on Sister Egan’s application, this Court granted bail until it could decide the appeal on the merits. Without hearing further oral argument, the Court proceded on March 2, 1971 to affirm the judgment of contempt. Sister Egan then filed a petition for rehearing, and the Court en banc heard argument on April 5, 1971.6
The Government did not suggest during reargument before the Court en banc, or at any time in this proceeding, that it did not employ wiretaps nor that any electronic surveillance that may have been utilized was authorized by court order. Since Sister Egan has not yet been afforded a hearing regarding her allega*202tions of illegal electronic surveillance by the Government, for the purpose of this appeal we assume her allegations to be true.
Three primary issues are raised by this ease: first, whether the procedure provided by 18 U.S.C.A. § 2518(10) (a) for the suppression of evidence derived from illegally intercepted communications is available to Sister Egan under the present circumstances; second, whether a district court may order Sister Egan to testify before a grand jury, if such testimony would violate an express congressional prohibition; third, whether Sister Egan has a constitutional right to refuse to answer questions propounded to her before a grand jury when the basis for the questions is electronic surveillance of her conducted by the Gov-ernmment in violation of the Fourth Amendment.
I
Title III of the Omnibus Crime Control and Safe Streets Act of 1968 is applicable to the first issue raised by Sister Egan. Section 2515 of the Act, 18 U.S.C.A. § 2515, provides:
“Whenever any wire or oral communication has been intercepted, no part of the contents of such communication and no evidence derived therefrom may be received in evidence in any trial, hearing, or other proceeding in or before any court, grand jury, department, officer, agency, regulatory body, legislative committee, or other authority of the United States, a State, or a political subdivision thereof, if the disclosure of that information would be in violation of this chapter.” (emphasis supplied).
Section 2515 is an unequivocal bar to questioning one before a grand jury if the questions are derived from electronic surveillance conducted in the absence of a properly issued warrant and aimed at the witness, if the witness himself objects to the interrogation. See 18 U.S.C.A. § 2511, § 2516, § 2518. The prohibition of § 2515 is in accord with Congressional findings set forth in § 801 of the Act of 1968, which explain that the purpose of Title III of the Act is, inter alia, “to protect effectively the privacy of wire and oral communications” and “the integrity of court and administrative proceedings.” 7
In his dissent, Judge Gibbons interprets this view as meaning that if illegal wiretaps are used against A, then A himself is precluded from voluntarily revealing the contents of the overheard communication. We do not so read § 2511 (1) (c). Instead, we suggest that it un-qualifiedly bars the party malting the illegal tap; not the party who has been victimized — the “aggrieved party.”
The Government contends, however, that although Congress in § 2515 specifically prohibited the disclosure to a grand jury of evidence derived from illegal wiretaps, nevertheless Congress excluded grand jury witneses from availing them*203selves of the remedy provided by § 2518 (10) (a). Section 2518(10) (a) states:
“Any aggrieved person in any trial, hearing, or proceeding in or before any court, department, officer, agency, regulatory body, or other authority of the United States, a State, or a political subdivision thereof, may move to suppress the contents of any intercepted wire or oral communication, or evidence derived therefrom, on the grounds that—
“(i) the communication was unlawfully intercepted;
(ii) the order of authorization or approval under which it was intercepted is insufficient on its face; or
(iii) the interception was not made in conformity with the order of authorization or approval.”
The initial requirement for the invocation of § 2518(10) (a) procedure is that the moving party be an “aggrieved person.”
Section 2510(11) defines “aggrieved person” for the purpose of the Act of 1968 to mean “a person who was a party to any intercepted wire or oral communication or a person against whom the interception was directed.” Certainly, Sister Egan is an “aggrieved person” within the meaning of § 2510(11), because she alleges without contradiction that she “was a party to [an] intercepted wire or oral communication.”
The fact that a grand jury hearing is not specifically listed in § 2518(10) (a) as a proceeding to which the section applies does not prevent Sister Egan from pursuing this statutory remedy. § 2518 (10) (a) does not indicate that the listed proceedings are exclusively the ones for which the remedy is to be exercised. And in any event, § 2518(10) (a) states that a motion by an aggrieved person to suppress may be made regarding the introduction of evidence obtained by illegal wiretapping in “any * * * hearing, or proceeding * * * before any * * * authority of the United States.” A grand jury is empanelled and proceeds under the “authority of the United States,” and thus is included in the class of proceedings to which § 2518(10) (a) is applicable. See Hale v. Henkel, 201 U.S. 43, 66, 26 S.Ct. 370, 50 L.Ed. 652 (1906); Cobbledick v. United States, 309 U.S. 323, 327, 60 S.Ct. 540, 84 L.Ed. 783 (1940). Therefore, the Act of 1968 would appear to be clear in its mandate and application to the facts of this case.
Even if the absence of the phrase “grand jury” from § 2518(10) (a) is significant, such omission would appear to be overcome by § 702 of the Organized Crime Control Act of 1970, amending title 18 by adding a new section, § 3504.8
In the course of contesting the right of Sister Egan to object to an interrogation *204based on information obtained by wiretaps Judge Gibbons refers to Jones v. United States, 362 U.S. 257, 80 S.Ct. 725, 4 L.Ed.2d 697 (1960); Goldstein v. United States, 316 U.S. 114, 62 S.Ct. 1000, 86 L.Ed. 1312 (1942) ; and Nar-done v. United States, 308 U.S. 338, 60 S.Ct. 266, 84 L.Ed. 307 (1939). None of these cases holds that a grand jury witness may not object to questions based on illegal wiretaps directed at the witness himself. In Jones, the defendant objected to the introduction of evidence obtained in violation of the Fourth Amendment. Although Jones was not the owner of the premises that were improperly searched, he was held to have had standing to object since he was the one at whom the search was directed. In Goldstein, the defendant sought to object to the introduction of evidence by two witnesses, whom the defendant claimed had been induced to testify because of illegal wiretaps directed at them (substantially the same problem covered in Aider-man v. United States, 394 U.S. 165, 39 S.Ct. 961, 22 L.Ed.2d 176 (1969).9 In Nardone, the Supreme Court reversed a conviction because it was based in part upon evidence derived from illegal wiretaps.
To support the view that the exclusionary rule is available only to a party and not to a witness who appears before a grand jury, Judge Gibbons points to the Senate Report relating to § 2515 and emphasizes the reference in it to Walder v. United States, 347 U.S. 62, 74 S.Ct. 354, 98 L.Ed. 503 (1954). However, Walder at no place indicates that a witness before a grand jury who has been aggrieved by illegal wiretaps may not take steps to exclude such information. It merely holds that a defendant may not commit perjury and then use the Fourth Amendment as “a shield against contradiction of his untruths.” Such principle is in no way applicable to Sister Egan.
Ordinarily, courts do not resort to the legislative history of an act in construing a statute such as this one which is clear on its face. In construing a Congressional enactment the Supreme Court said in United States v. Oregon, 366 U.S. 643, at 648, 81 S.Ct. 1278, 1281, 6 L.Ed.2d 575, “Having concluded that the provisions of [the Act] are clear and unequivocal on their face, we find no need to resort to the legislative history of the Act.” See also Essex County and Vicinity Dist. Council of Carpenters and Millwrights v. N. L. R. B., 332 F.2d 636, at 641 (1964). Nonetheless, it has been suggested here that the legislative history of the Act of 1968 expresses the Congressional intent more accurately than its explicit language. In particular it is contended that while admittedly Congress has forbidden evidence seized by illegal wiretaps to be used before a grand jury, nevertheless the Act’s legislative history reveals that Congress did not intend to permit the remedy provided by § 2518(10) (a) to be raised by a grand jury witness.10
*205We do not believe the legislative history is dispositive of the question whether Sister Egan may proceed pursuant to § 2518(10) (a) to secure a hearing regarding her allegation of illegal wiretaps. The legislative history is, to say the least, ambiguous.
The reference to United States v. Blue, 384 U.S. 251, 86 S.Ct. 1416, 16 L.Ed.2d 510 (1965) and the expressed intention not to change the rule contained in Blue raise serious questions as to the meaning of the legislative history. The holding of Blue relevant to the present issue was merely that if the Government had submitted to a grand jury evidence obtained in violation of the Fifth Amendment, by itself such action did not entitle Blue to have an indictment dismissed. The rationale underlying Blue, as expressed by Justice Harlan, is that the exclusionary rule interdicts the use of tainted evidence, but “does not extend to barring the prosecution altogether.” 384 at 255, 86 S.Ct. at 1419.11 But see United States v. Tane, 329 F.2d 848 (2nd Cir. 1964).
Sister Egan, of course, is not attempting to have an indictment dismissed. Her complaint, unlike that of Blue, is that she has been called to testify before the grand jury as a result of the Government’s improper wiretaps, and that had it not been for such wiretaps the Government would not be seeking to interrogate her. It is the grand jury’s questioning itself which will create the harm of which she complains. In view of the express provision of § 2515 forbidding the use before a grand jury of the fruits of illegal wiretaps, it is highly unlikely that Congress intended to exclude grand jury witnesses who are also aggrieved persons within the meaning of the Act from the procedural remedy provided by § 2518(10) (a). The reference in the legislative history to Blue demonstrates at most a congressional intent to preclude an attack on a grand jury investigation by one whose interest in such investigation is not as a witness, but as a defendant, and instead to require such person to move for the exclusion of the questionable evidence after the indictment or at a time designated by the rules of criminal procedure.12
Thus, when Congress stated that there was no intent to change the general rule contained in Blue, it was expressing a purpose not to alter the principle that Fifth Amendment grounds are an insufficient basis to quash an indictment. The context of the present case is substantially different from that of Blue, because Sister Egan is complaining of violations of her Fourth Amendment right, a right significantly different from that set forth in the Fifth Amendment.13 She is not attempting to block *206an indictment that might be returned by the grand jury but rather is asserting her right as a citizen to vindicate her privilege which protects her from unreasonable searches and seizures, regardless whether she will ever be indicted.
The sentence which appears before the Blue citation in the legislative history-— “Normally, there is no limitation on the character of evidence that may be presented to a grand jury, which is enforeible by an individual.”14 — implies that Congress recognized there might be exceptions to the general rule. Indeed, in certain circumstances where the compulsion of testimony in a grand jury proceeding would violate a constitutional statutory, or common law privilege of the grand jury witness, there are numerous precedents for permitting a witness to invoke the protections afforded by such privileges. E. g., Hoffman v. United States, 341 U.S. 479, 71 S.Ct. 814, 95 L.Ed. 1118 (1951); Blau v. United States, 340 U.S. 332, 71 S.Ct. 301, 95 L.Ed. 306 (1951); Silverthorne Lumber Company v. United States, 251 U.S. 385, 40 S.Ct. 182, 64 L.Ed. 319 (1920); Dionisio v. United States, 442 F.2d 276 (7th Cir. 1971); Caldwell v. United States, 434 F.2d 1081 (9th Cir. 1970), cert, granted, 402 U.S. 942, 91 S.Ct. 1616, 29 L.Ed.2d 109 (1971). Although Congress expressed an intention to adhere to the “general rule,” there is no basis for believing that it was excluding the usual exceptions to the general rule.
Blau v. United States, 340 U.S. 332, 71 S.Ct. 301, 95 L.Ed. 306 (1951) is especially appropriate in this regard. There, the petitioner was called before a grand jury investigating the activities of the Colorado Communist Party. When questioned regarding the whereabouts of his wife, Blau refused to answer, relying solely upon the privilege attaching to confidential communications between husband and wife. The district court, despite the assertion of the husband-wife privilege, sentenced Blau for contempt. The Supreme Court reversed on the ground that the husband-wife privilege shielded Blau from disclosing what was presumed to be a confidential communication from his wife. If a common law doctrine may support a grand jury witness’s refusal to testify, it follows that an express statutory prohibition would require a similar result. Since Sister Egan was a party to the conversations monitored illegally, she has a personal interest in refusing to answer questions derived from the Government’s illegal invasion of her privacy.
In short, while the legislative history regarding 2518(10) (a) is not completely clear, it appears to indicate an intent that one who has been illegally wiretapped but is not a witness called by the grand jury may not move to suppress; and that even a witness or defendant who objects to the use of illegal wiretaps in the proceedings may not move to quash the entire proceeding of even an indictment growing out of it.
The dissent takes the position that footnote 9 of Alderman v. United States, 394 U.S. 165, 175, 89 S.Ct. 961, 22 L.Ed. 2d 176 (1969) demonstrates that the Supreme Court views the remedy provided by § 2518(10) (a) of the Act of 1968 as inapplicable to the circumstances of this case. Indeed, one of the main contentions in this case has been that footnote 9 of Alderman clearly indicates that § 2518(10) (a) does not confer standing upon one who is hailed before a grand jury and questioned on the basis of material obtained from the witness himself as a result of improper eavesdropping.
To understand more fully the implication of footnote 9, it is appropriate to review Alderman. The defendant there was convicted of a conspiracy to transmit threats in interstate commerce. Thereafter, he claimed he discovered that the evidence used to convict him was obtained as a result of illegal eavesdropping and petitioned the Supreme Court to remand the case so that the district court might hold a hearing to determine whether the surveillance was illegal and *207if so, whether the evidence introduced at his trial was so tainted as to vitiate the conviction. The Solicitor General conceded that wiretapping had been employed, but contended that no hearing was necessary because none of the conversations overheard was arguably relevant.
The Supreme Court held (1) that it could not rely on the representations of the Solicitor General regarding the relevancy of the material obtained by the wiretaps, but (2) that the “established principle is that suppression of the product of a Fourth Amendment violation could be successfully urged only by those whose rights were violated by the search itself, not by those who are aggrieved solely by the introduction of damaging evidence” (emphasis supplied). 394 U.S. at 171-172, 89 S.Ct. at 965. Thus, the case was remanded for a district court hearing.
In the course of examining the proposition that Fourth Amendment protection is available only to the one whose personal rights have been violated, and not available to a third party, Justice White said:
“Of course, Congress or state legislatures may extend the exclusionary rule and provide that illegally seized evidence is inadmissible against anyone for any purpose.” 9 394 U.S. at 175, 89 S.Ct. at 967-968.
Footnote 9 of Alderman reads as follows:
“9. Congress has not done so. In its recent wiretapping and eavesdropping legislation, Congress has provided only that an ‘aggrieved person’ may move to suppress the contents of a wire or oral communication intercepted in violation of the Act. Title III, Omnibus Crime Control and Safe Streets Act of 1968, 82 Stat. 221 (18 U.S.C. § 2518(10) (a) 1964 ed., Supp. IV). The Act’s legislative history indicates that ‘aggrieved person,’ the limiting phrase currently found in Fed.Rule Crim.Proc. 41(e), should be construed in accordance with existent standing rules. See S.Rep., No. 1097, 90th Cong., 2d Sess., at 91, 106.”
Fed.Rules Crim.Proc. 41(e), referred to in footnote 9 of Alderman, provides as follows:
(e) Motion for Return of Property and to Suppress Evidence. A person aggrieved by an unlawful search and seizure may move the district court for the district in which the property was seized for the return of the property and to suppress for use as evidence anything so obtained on the ground that (1) the property was illegally seized without warrant, or (2) the warrant is insufficient on its face, or (3) the property seized is not that described in the warrant, or (4) there was not probable cause for believing the existence of the grounds on which the. warrant was issued, or (5) the warrant was illegally executed. The judge shall receive evidence on any issue of fact necessary to the decision of the motion. If the motion is granted the property shall be restored unless otherwise subject to lawful detention and it shall not be admissible in evidence at any hearing or trial. The motion to suppress evidence may also be made in the district where the trial is to be had. The motion shall be made before trial or hearing unless opportunity therefor did not exist or the defendant was not aware of the grounds for the motion, but the court in its discretion may entertain the motion at the trial or hearing.
In view of the language of Rule 41(e), it seems clear that what Justice White is saying is that in a criminal trial — such as Alderman — the defendant may object only if the illegal search was directed at him. If it was directed at a third party, however, such third party may protect himself, if he desires, by moving under Rule 41(e). In Grant v. United States, 282 F.2d 165, 168 (2nd Cir. 1960), IRS agents obtained from two physicians records and papers relating to income tax matters. Fearing that these records might lead to a grand jury investigation, the physicians moved, prior to indict*208ment, under Rule 41(e) for the suppression of the documents. The District Court directed the Government to show cause why the physicians were not entitled to the return of their documents. The Government appealed and the Second Circuit stated that Rule 41(e) may be invoked by a citizen who has not been indicted and is not a party to a criminal proceeding. Judge Friendly, speaking for the Court, said:
“The classical exposition of the nature of [a rule 41(e) motion] is Judge Hough’s statement in United States v. Maresea, 266 F. 713, 717 (S.D.N.Y. 1920):
“Whenever an officer of the court has in his possession or under his control books or papers, or (by parity of reasoning) any other articles in which the court has official interest, and of which any person (whether party to a pending litigation or not) has been unlawfully deprived, that person may petition the court for restitution. This I take to be an elementary principle, depending upon the inherent disciplinary power of any court of record.
“Attorneys are officers of the court, and the United States attorney does not by taking office escape from this species of professional discipline. Thus power to entertain this motion depends on the fact that the party proceeded against is an attorney, not that he is an official known as the United States Attorney. It is further true that the right to move does not at all depend on the existence of this indictment; it might be made, were no prosecution pending.”15
Likewise in Centracchio v. Garrity, 198 F.2d 382 (1st Cir.), cert, denied, 344 U.S. 866, 73 S.Ct. 108, 97 L.Ed. 672 (1952), a petitioner, although not indicted at the time of his motion, moved under Rule 41(e) to suppress information he had volunteered to the Treasury Department, alleging the use of such information by the Government violated the Fifth Amendment. The District Court entertained the motion but denied the petition on the merits, finding that no violation of Centracchio’s constitutional rights had occurred. The First Circuit held that the denial of the motion was appealable, because the motion was an independent proceeding and not “in the course of a criminal proceeding, since [n]o such proceeding was pending before the district court.” The Court stated:
“ * * * it has long been accepted that where evidence, obtained by an unconstitutional search and seizure in violation of the Fourth Amendment, is in the hands of a United States Attorney, a federal district court may entertain and grant relief on a petition, filed even prior to any indictment, seeking a return of the papers or property unconstitutionally seized and the suppression of the same as evidence.” 198 F.2d at 385-386.
The Court went on to note that Centracchio’s petition and the evidence supporting it “did not disclose that petitioner had yet suffered any violation of his constitutional rights, either under the Fourth or Fifth Amendment.” 198 F.2d at 388. For that reason and because Centracchio would be able to raise his *209Fifth Amendment rights at trial,15a the Court decided that the petition before it lacked equity and should have been dismissed.
Centracchio, therefore, supports the proposition that district courts do have jurisdiction under Rule 41(e) to hear and decide pre-indictment motions seeking to suppress evidence seized in violation of the Fourth Amendment. The equitable considerations upon which the Centracchio court based its decision are not present here: Sister Egan’s allegations on their face reveal a Fourth Amendment violation; and unlike Cen-tracchio Sister Egan by virtue of the Government’s grant of immunity is unlikely to become a criminal defendant and thus will not be able to vindicate her rights in a future criminal proceeding.
Considered in light of the issues decided in Alderman, footnote 9 means that the Safe Streets Act of 1968 did not adopt a definition of “aggrieved person” broader than constitutionally required. Since Alderman decided that the Fourth Amendment creates rights that may be vindicated only by the one who suffered a search and seizure conducted in violation of the Fourth Amendment, the definition of “aggrieved person” in the Act of 1968 is in accord with constitutional standards set forth in Alderman. In any event because Sister Egan alleges that her rights under the Act were violated by an illegal wiretap addressed directly to conversations to which she was a party, she falls within the definition of “aggrieved person” under the Act, and whatever judicial interpretation of the Act exists in footnote 9 of Alderman is not inconsistent with this view of the Act. Indeed, footnote 9 supports such an interpretation.
II
Assuming arguendo that the Government is correct that the procedure provided by § 2518(10) (a) is inapplicable to this case, there is nonetheless a second ground requiring reversal. It seems beyond question that a district court may not compel the violation of an express congressional prohibition. Section 2515 of the Act directly and clearly forbids the presentation to a grand jury of evidence derived from the contents of oral communications improperly obtained. The Government does not except to such position.
As pointed out previously, § 801 indicates that one of the Act’s purposes is to protect “the privacy of wire * * * communications” and “to protect the integrity of court[s] by forbidding the contents of such conversations from being introduced into evidence. In order to effectuate the legislative purpose, Congress prohibited not only the introduction of the contents of conversations illegally obtained, but also any evidence derived therefrom. Such a rule has a two-fold effect — to protect the courts from becoming unwilling participants in illegal governmental activity, and to protect the privacy of citizens. In framing the legislation in question, Congress adopted a traditional judicial approach to Fourth Amendment problems — a prohibition against the use of evidence seized in violation of the Amendment, and also a prohibition against the use of evidence acquired by the Government as a result of the inhibited conduct.
In the present case the District Court had a duty to follow the express direction of Congress found in § 2515. By ordering -Sister Egan to testify before the grand jury when Congress has legislated the exclusion of such evidence, the District Court simply acted inconsistently with the legislative mandate.
The rule provided by § 2515 is the legislative parallel of prior judicial decisions holding that the federal courts should not receive evidence obtained in violation of federal statutes. 47 U.S. C.A. § 605 prohibits the publication of the contents of illegally intercepted wire communications and thus, in many re*210spects, is similar to § 2511(1) (c) of the Omnibus Crime Control Act. In Nar-done v. United States, 302 U.S. 379, 58 S.Ct. 275, 82 L.Ed. 314 (1937), the defendants were convicted by evidence which included a federal agent’s testimony of statements made by the defendants in telephone conversations which had been intercepted by wiretaps. Since § 605 provides that “no person not being authorized by the sender shall intercept any communication and divulge or publish the existence, contents, substance, purport, effect or meaning of such intercepted communication to any person * * the Court ruled that it was impermissible to receive into evidence the testimony of the federal agent relating to the overheard telephone conversations. The statute in the present case is a stronger one than that considered in Nardone, because § 605 did not specifically prohibit the use of the contents of intercepted telephone communications in a criminal proceeding, whereas § 2515 expressly creates a rule of evidence relevant to criminal proceedings.
The fact that Sister Egan has been granted § 2514 immunity does not deprive her of standing to raise § 2515 as a defense to a proposed judgment of civil contempt, because she is not complaining of Fifth Amendment violations, but rather of Fourth Amendment ones. Surely, even though Sister Egan has been offered immunity from prosecution, she continues to have a substantial interest in preventing the Government from compounding its original violation of her privacy by forcing her to answer questions that would concededly not be asked absent the information discovered through the use of unwarranted wiretaps.
III
Finally, even if Sister Egan has no statutory defenses to the judgment of civil contempt, the Fourth Amendment would require that the case be remanded to the District Court for a hearing regarding her allegations that the grand jury questions in this case are the fruits of unconstitutional electronic surveillance.
The Government argues that in the context of a constitutional defense to the District Court’s order to testify before the grand jury, Sister Egan is without standing to challenge the lawfulness of the Government’s acquisition of information by wiretaps placed on her telephone. As the Supreme Court recently stated, “[standing] concerns, apart from the ‘case’ or ‘controversy’ test, the question whether the interest sought to be protected by the complainant is arguably within the zone of interests to be protected or regulated by the statute or constitutional guarantee in question.” Association of Data Processing Service Orgs., Inc. v. Camp, 397 U.S. 150, 153, 90 S.Ct. 827, 830, 25 L.Ed.2d 184 (1970).16 See Investment Co. Institute v. Camp, 401 U.S. 617, 91 S.Ct. 1091, 28 L.Ed.2d 367 (1971). Ordinarily a citizen has standing to complain of a violation of Fourth Amendment rights when an illegal search and seizure has been directed against him. Alderman v. United States, supra; Jones v. United States, 362 U.S. 257, 261, 80 S.Ct. 725, 4 L.Ed.2d 697 (1960); See Greenspan and White, Standing to Object to Search and Seizure, 118 U.Pa.L. Rev. 333 (1970). The fact that the question of standing arises in a grand jury investigation does not alter the result.17
*211The leading case in this field is Silver-thorne Lumber Co. v. United States, 251 U.S. 385, 40 S.Ct. 182, 64 L.Ed. 319 (1920), which included a number of elements similar to those arising here. Frederick and Asa Silverthorne as well as the Silverthorne Company were indicted for conspiracy to defraud the Government by obtaining payment for materials not delivered. Thereafter, papers belonging to Frederick Silverthorne and to the Silverthorne Company were seized in violation of the Fourth Amendment rights of the corporation and the individual, and subsequently returned to the owners only after a petition had been filed by them. Then a grand jury issued a subpoena duces tecum for the production of the very papers previously seized. The Company and Frederick Silverthorne refused to obey the subpoena on the ground that it was based on the poisonous fruits of the improper search and seizure. The district court held both the Company and Frederick Silverthorne in civil contempt. On writ of error to the Supreme Court the judgment of contempt was reversed. Justice Holmes, writing for the Court, stated that grand jury witnesses may not constitutionally be held in contempt for failing to respond to a subpoena when the Government “ * * * seeks to maintain its right to avail itself of the knowledge obtained by that means which otherwise it would not have had.” 251 U.S. at 391, 40 S.Ct. at 182. And thus in Sil-verthorne the corporation and Frederick Silverthorne were permitted to challenge a judgment of contempt for failing to respond to a subpoena issued by a grand jury, irrespective of the eventual action of the grand jury and without regard to whether they ultimately would be brought to trial. The Court in Silver-thorne did not require that the petitioners defer challenging the Government’s seizure of information until such time as they would be tried. The rationale for Silverthorne, in the words of Mr. Justice Holmes, is that “[t]he essence of a provision forbidding the acquisition of evidence in a certain way is that not merely evidence so acquired shall not be used before the Court but that it shall not be used [by the Government] at ail.” (emphasis supplied) 251 U.S. at 392, 40 S.Ct. at 183. This language would logically appear to mean that the Fourth Amendment prevents the Government from using illegally seized evidence as the basis for questioning aggrieved parties before a grand jury.18 As we understand the holding of Silverthorne it would appear to control the issue raised by Sister Egan. Furthermore, the resolute language contained in Silverthorne has been frequently reasserted by the Supreme Court. Indeed, as late as 1968, although in a context somewhat different from that now present, the Court referred to Silverthorne and reaffirmed the reasoning which Sister Egan applies to her case. Harrison v. United States, 392 U.S. 219, 222, 88 S.Ct. 2008, 20 L.Ed.2d 1047 (1968).
The Government insists that Silver-thorne is distinguishable from the present case because Sister Egan has been granted “transactional” immunity, and the defendants in Silverthorne did not receive such protection. There are a number of answers to this contention. First, as previously indicated, the language of Silverthorne established a broad prohibition against the Government’s obtaining information as a result of conduct violative of the Fourth Amendment. The Supreme Court did not adumbrate in any way the distinctions suggested by the Government here. Second, one of the petitioners was a corporation, and therefore not protected by the Fifth Amendment. Thus, in one *212sense Sister Egan and the Silverthorne Company are in a similar posture since neither was entitled to complain of Fifth Amendment violations — she because of her immunity. Third, the fact that Sister Egan has been offered “transactional” immunity regarding her testimony before the grand jury does not dissipate the harm which she has suffered as a direct result of the illegal wiretaps and the Government’s attempt to question her based on them. Fourth, the fact that there were indictments in Silverthorne actually makes Sister Egan’s case a stronger one for permitting the attack on the subpoena at this point, since this is the only time Sister Egan may have the opportunity to move to vindicate her constitutional right to privacy.
The Government also contends that normally there is no limitation on evidence that may be presented to a grand jury which may be enforced by an individual witness, and that this is but fore the grand jury has no standing to another way of saying that a witness be-objeet to what evidence is adduced before the grand jury. For this proposition, the Government refers to United States v. Blue, supra. However, the reliance is misplaced.
In Blue, the defendant was indicted for evading income taxes. Prior to indictment, the Government had filed jeopardy assessments against Blue’s property, and Blue filed petitions to remove them. Blue thereafter moved to dismiss the indictment on the ground that the petitions to reverse the jeopardy assessments required him to make statements which would incriminate him in the criminal proceedings in violation of his Fifth Amendment rights. The district court granted Blue’s petition, and the Supreme Court took jurisdiction since the district court’s judgment was in effect a motion in bar and future prosecution of Blue would be forever prevented. The Supreme Court reversed on the ground that Blue would at most be entitled to suppress the evidence and its fruits if they were sought to be used against him at a criminal trial, stating (384 U.S. at 255, 86 S.Ct. at 1419):
“ * * * this Court in a number of areas has recognized or developed exclusionary rules where evidence has been gained in violation of the accused’s rights under the Constitution, federal statutes, or federal rules of procedure. Weeks v. United States. 232 U.S. 383, 34 S.Ct. 341, 58 L.Ed. 652; Rogers v. Richmond, 365 U.S. 534, 81 S.Ct. 735, 5 L.Ed.2d 760; Mapp v. Ohio, 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081; Nardone v. United States, 308 U.S. 338, 60 S.Ct. 266, 84 L.Ed. 307; Mallory v. United States, 354 U.S. 449, 77 S.Ct. 1356, 1 L.Ed.2d 1479. Our numerous precedents ordering the exclusion of such illegally obtained evidence assume implicitly that the remedy does not extend to barring the prosecution altogether." (emphasis added).
Blue is clearly inapposite here. Blue had been indicted, and the thrust of his complaint was not that his privacy was invaded or indeed that his constitutional rights had been infringed, but only that if the Government proceeded to prosecute him, he could then assert his Fifth Amendment right and therefore the indictment should be quashed. In a footnote, the Court specifically pointed out that it is not even “contended that tainted evidence was presented to the grand jury.” 384 U.S. at 255, 86 S.Ct. at 1419. Accordingly, it was clear that Blue had to await trial before properly moving to suppress the evidence to which he objected. Finally, it was the Fifth Amendment and not the Fourth that was invoked in Blue. The very language of the Fourth Amendment demonstrates that its reach is far broader than that "of the Fifth.
The Government places great stress on the fact that Sister Egan has received immunity. However, this fact does not answer the constitutional issue that has been raised. Sister Egan states that if she has a constitutional right not to have her privacy invaded by illegal wiretaps, it is an inadequate response for the Gov*213ernment to say in effect, we may have invaded your privacy but we will not prosecute you as a result of our misconduct, and thus you have no standing to complain of the invasion of your privacy.19 The Government’s answer is really a nonsequitur, and the Government does not come to grips with the fact that Sister Egan’s constitutionally protected right of privacy has been invaded. Instead, a careful analysis of the Government’s position demonstrates that it deals solely with her right not to be compelled to incriminate herself as being satisfied by the immunity which has been granted. Immunity deals with the witness’ privilege not to incriminate himself. The witness still has the right that his person and home not be improperly searched and if it is, under principles now well settled, the fruits of such search may not be used.
If the Government were correct in its approach, numerous citizens could have their privacy invaded by wiretaps and be brought before a grand jury for questioning regarding the fruits of such wiretaps. Under the logic of the Government’s contention regarding standing if the Government were to file an application for immunity, the right of such citizens to be free from questions based on the illegal wiretaps would be placed beyond the reach of judicial review. We do not believe that the command of the Fourth Amendment can be so easily circumvented.20
The Government argues that notwithstanding Silverthorne, two circuits, the Second and the Ninth, have ruled that a grand jury witness may not challenge the source of information supporting the grand jury’s decision to question the witness: Carter v. United States, 417 F.2d 384 (9th Cir. 1969); United States ex rel. Rosado v. Flood, 394 F.2d 139 (2nd Cir. 1968).
In Carter, the Ninth Circuit considered an appeal from an order of a district court requiring members of the Black Panther Party who had been granted “transactional” immunity to testify before a grand jury. One of the contentions concerned the appellants’ belief that some of the questions propounded by the grand jury were based upon information stemming from illegal wiretaps directed against a third party. Although the Court stated, “As [grand jury] witnesses, they have no standing to question the source of the government’s information,” 417 F.2d at 388, such broad language was unnecessary because the decision could have been based on the ground, as in Alderman v. United States, that a citizen may not vicariously raise the Fourth Amendment rights of a third party. Since appellants in Carter were attempting to assert on their own behalf the protections afforded by the Fourth Amendment to a third party who was the victim of illegal wiretaps, Carter is distinguishable from Sister Egan’s case; Sister Egan has asserted that she, personally, was the victim of unconstitutional surveillance. To the extent the language of Carter controls the present ease, we should decline to follow it as it is in conflict with Silverthorne. Subsequent to Carter, the Ninth Circuit, in Caldwell v. United States, 434 F.2d 1081 (1970) cert, granted 402 U.S. 942, 91 S.Ct. 1616, 29 L.Ed.2d 109 (1971) reserved decision on the issue whether a grand jury witness is entitled to an Alderman hearing when he alleges his grand jury subpoena was based upon information obtained in violation of the Fourth *214Amendment. Thus, in the view of the Caldwell panel, this issue, notwithstanding Carter, remains unresolved in the Ninth Circuit.21
Caldwell makes it clear that a grand jury witness does have standing to challenge a grand jury subpoena on the ground that the compulsion to testify would encroach upon a constitutional right — in Caldwell the protection of the First Amendment. Caldwell, a reporter who had interviewed Black Panther Party members, was subpoenaed to testify before a federal grand jury. Because he feared that to appear would hinder his effectiveness as a reporter, Caldwell moved to quash the subpoena as violative of the First Amendment’s guarantee of freedom of the press. The District Court refused to quash the subpoena, but recognizing the importance of the First Amendment question ordered that Caldwell need not reveal to the grand jury confidential information received in his professional capacity. Despite the order, Caldwell refused to obey the subpoena on the ground his mere appearance before a grand jury would intimidate potential sources of information who wished to remain anonymous. Caldwell was held in contempt. The Ninth Circuit ruled that the order fashioned by the District Court was insufficient to satisfy the requirements of the First Amendment and reversed, holding that where a grand jury subpoena would jeopardize freedom of the press, the Government must demonstrate a “compelling need for the witness’s presence before judicial process properly can issue to require attendance.” 434 F.2d at 1089.
In Rosado, a case relied upon as support for the sweeping language contained in Carter, the Second Circuit considered a habeas corpus petition brought by a state prisoner who had been confined for refusing to answer questions before a New York grand jury, despite a grant of immunity under New York law. Rosado contended that compelling him to answer questions concerning the contents of intercepted telephone conversations to which he had been a party would violate 47 U.S.C.A. § 605 and the Federal Constitution. Regarding Rosado’s claims, the court primarily relied upon Blair v. United States, 250 U.S. 273, 39 S.Ct. 468, 63 L.Ed. 979 (1919). Blair involved a grand jury investigating violations of the Corrupt Practices Act. Three of the witnesses called before the grand jury refused to testify on the ground the Corrupt Practices Act was unconstitutional because it attempted to regulate selection by political parties of candidates for the Senate. The Supreme Court ruled that as mere witnesses they were without standing to challenge the validity of a statute, the violation of which was the subject of the grand jury investigation. The Supreme Court reasoned that the witnesses, as distinguished from future defendants, had insufficient interest in the constitutionality of a statute to require the Court to overcome its reluctance to pass upon the validity of an act of Congress. However, the Supreme Court was careful to point out that there were cases in which a witness before a grand jury could assert rights not to testify. It stated that:
“The duty [to testify before a grand jury] * * * is subject to mitigation in exceptional circumstances; there is a constitutional exemption from being compelled in any criminal case to be a witness against oneself, entitling the witness to be excused from answering anything that will tend to incriminate him * * *; some confidential matters are shielded from considerations of policy, and perhaps in other cases for special reasons a witness may be excused from telling all that he knows.” 250 U.S. at 281, 39 S.Ct. at 471.
*215Hence, on analysis, the holding of Blair would appear to be a narrow one, deciding only that a grand jury witness may not challenge the constitutionality of a statute the alleged violation of which is the subject of a grand jury inquiry. Since the Supreme Court in Blair was careful to point out that grand jury witnesses do have standing to litigate some privileges, such as the Fifth Amendment, we respectfully suggest that the Rosado panel read the holding in Blair too broadly. Indeed, cases far more recent than Blair have held that grand jury witnesses have the requisite standing to raise a variety of privileges. E. g. Blau v. United States, supra; Caldwell v. United States, supra; Dionisio v. United States, supra; In re Bonanno, 344 F.2d 830 (2nd Cir. 1965). But see United States ex rel. Ciffo v. McClosky, 272 F.Supp. 604 (S.D.N.Y.1967).
Furthermore, to some extent Rosado is distinguishable from the present case because Rosado implicated a witness called before a state grand jury, while Sister Egan is before a federal grand jury. Federal courts have traditionally exhibited a reluctance to interfere with state criminal proceedings. Compare Schwartz v. Texas, 344 U.S. 199, 73 S.Ct. 232, 97 L.Ed. 231, with Nardone v. United States, 302 U.S. 379, 58 S.Ct. 275. 82 L.Ed. 314 (1937); see Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971). Insofar as Rosado is not distinguishable on the basis that the holding there stems from a reluctance of federal courts to upset the delicate balance of federal-state relations, we should decline to follow it because it would appear Rosado misapplied the teaching in Blair and also is in conflict with Silverthome.
It is appropriate at this point to repeat a statement by Chief Judge Lum-bard — a year after Rosado — in Bivins v. Six Unknown Named Agents of the Federal Bureau of Narcotics, 409 F.2d 718, 724 (2nd Cir. 1969), cert, granted, 399 U.S. 905, 90 S.Ct. 2203, 26 L.Ed.2d 559 (1970):
“ * * * the primary thrust of the Bill of Rights is to shield citizens from certain actions by the government. The implication of judicial remedies to provide this shield follows naturally from the declaration of a right * *
Sister Egan’s right to be free from unreasonable searches has already been violated as a result of the Government’s use of illegal wiretaps. The Government now seeks to profit from its unconstitutional conduct by propounding questions based on the improperly seized information. To deprive Sister Egan of a shield to ward off such activity would seriously rend the armor of the Fourth Amendment.22
The Government has suggested that to permit Sister Egan to require a hearing to determine whether she has been the victim of illegal surveillance merely by alleging that the questions were derived from such wiretaps would unreasonably impede the progress of the grand jury investigation. However, there are precedents for such a procedure, some of them involving common law as well as constitutional or statutory rights. For example, the Second Circuit in In re Bonanno, supra, decided that the attorney-client privilege protects a grand jury witness from being forced to reveal conversations between himself and his attorney. Furthermore, the Second Circuit held that as a consequence of the protection afforded a grand jury witness, before imposing a judgment of contempt the District Court should conduct a hearing to determine whether the requisite attorney-client relationship did in fact exist at the time of the conversations in question. Likewise, in Blau v. United States, supra, a communication between a husband and wife was held presump*216tively privileged and beyond grand jury inquiry. The Court indicated that the Government might be able to overcome the presumption of confidentiality attaching to communications between husband and wife, and, of course, any such attempt would require a hearing.23
In the context of electronic surveillance, it is unlikely that hearings such as requested here would become a major interference with efficient grand jury investigations. Sister Egan is not asking that the grand jury be prevented from continuing its investigations or from returning an indictment against anyone found to have violated federal law. In fact the grand jury which has so far been unable to have the benefit of Sister Egan’s testimony has already returned various indictments relating to the questions posed to Sister Egan.
We assume that the Government will attempt to conduct surveillance within statutory and constitutional limits, and that only in a slight number of cases will there be a violation of the rules governing wiretapping. Thus, when the allegation of illegal surveillance is made in most cases the Government will simply represent to the court that no electronic surveillance has been employed by the Government. In a lesser number of cases the Government will produce in court the warrant by which it proceeded, and a brief inquiry will demonstrate that the warrant was properly obtained and that the surveillance did not exceed the authority of the warrant. Only in a minimal number of cases do we expect that the Government will be found to have conducted surveillance in violation of the statute and in these cases the hearing will not be overly complicated or lengthy, because the primary matter of inquiry would be whether the Government can demonstrate an independent basis, aside from the illegal surveillance, upon which to justify the questions propounded before the grand jury.
Certainly the possibility that some grand jury witnesses may seek Alderman hearings is not sufficient to cause a curtailment of an important right such as provided by the Fourth Amendment.24 And this is all the more so when the Government — which would have the bur*217den of proof in attempting to dull the edges of a constitutional right — has shown absolutely no evidence to support the proposition that standing to assert a Fourth Amendment right will disrupt the grand jury procedure.
The dissenters suggest that since there is no statistical evidence available indicating the degree to which federal agents might employ illegal wiretaps, considerations favoring evidentiary sanctions may not exist, and there is no basis for using the exclusionary rule. In support of this proposition Weeks v. United States, 232 U.S. 383, 34 S.Ct. 341, 58 L.Ed. 652 (1914) and Mapp v. Ohio, 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081 (1961) are cited. It is true that in Mapp, which applied the exclusionary rule to the states, the Court did demonstrate that state officers had not been complying with the Fourth Amendment rules. In Weeks, however, where the Court was dealing with the federal system — as we do here — no empirical study was employed to support the application of the exclusionary rule. Instead, Justice Day stated, 232 U.S. at 391-393, 34 S.Ct. at 344:
“The effect of the 4th Amendment is to put the courts of the United States and Federal officials, in the exercise of their power and authority, under limitations and restraints as to the exercise of such power and authority, and to forever secure the people, their persons, houses, papers, and effects, against all unreasonable searches and seizures under the guise of law.”
* * * * * *
“If letters and private documents can thus be seized and held and used in evidence against a citizen accused of an offense, the protection of the 4th Amendment, declaring his right to be secure against such searches and seizures, is of no value, and, so far as those thus placed are concerned, might as well be stricken from the Constitution. The efforts of the courts and their officials to bring the guilty to punishment, praiseworthy as they are, are not to be aided by the sacrifice of those great principles established by years of endeavor and suffering which have resulted in their embodiment in the fundamental law of the land.”
Finally, we must be ever mindful of the admonition that in a government of laws, the very existence of the Government will be imperiled if it fails to observe the law scrupulously. For the Government teaches the whole people by its example, and if the Government becomes a law breaker, it breeds contempt for law. To declare that the Government may commit crimes in order to secure the conviction of a criminal may well bring unfortunate retribution.25
