Opinion
Joe Otto’s distrust of his younger wife, Brenda Sue, bordered on the obsessive; his anxieties derived mainly from her uncertain relationship with another man, Marvin Elmer Mark. To confirm his suspicions, Joe secretly tape-recorded Brenda’s telephone calls from the family residence. These recordings captured a conversation between Brenda and her suspected paramour which added a new and horrifying dimension to Joe’s fears; the illicit alliance was a reality, but its object was not merely his wealth and marriage, it was his life itself.
Joe’s concerns proved to be well founded. Within 48 hours of the recorded conversation, he was found dead—bludgeoned to death in his own home. Shortly thereafter, the police discovered the secret recording and several other taped conversations. Brenda and Marvin Mark were charged and tried *1092 for first degree murder. A jury returned guilty verdicts against both defendants; each received a prison sentence of 25 years to life.
Prior to trial, both defendants moved to suppress the taped conversations on the grounds that Joe Otto had obtained them in violation of Title III of the Omnibus Crime Control and Safe Street Act of 1968 (18 U.S.C. §§ 2510-2520) (hereafter Title III or the Act) and that their introduction into evidence would therefore violate the exclusionary provision of the Act (18 U.S.C. § 2515). The trial court denied the pretrial motion and subsequently denied a renewed motion to suppress the tapes at the start of trial. The Court of Appeal affirmed the trial court’s rulings, holding that suppression was not compelled under federal or state law. 1
We granted review limited to the issue of the admissibility of the telephone conversations secretly recorded by the victim. 2 For the reasons set forth below, we conclude that under Title III the contents of the tapes could not properly be introduced into evidence. Because of the critical role played by the tapes at trial, we further conclude that the error requires reversal of the judgments of conviction.
Facts
Joe Otto was a 61-year-old electrician with a history of heart disease when, in September of 1986, he married Brenda Sue Delwiche, a 39-year-old divorced woman with two grown children. Brenda was Joe’s third wife.
The couple’s relationship was troubled from the start. Their courtship of the previous year and brief marriage were marked by jealousy and suspiciousness on Joe’s part, and cold-blooded calculation on the part of Brenda. She confided to a friend that she agreed to the marriage only because Joe was sick and probably would not live long; the marriage would provide financial security for herself and her daughters. Indeed, before she would agree to marry Joe, Brenda had apparently demanded a substantial cash payment, which she planned to invest with Marvin Mark.
Mark’s involvement with Brenda dated from August 1985, when he became a boarder in her home. He soon became her lover and they were *1093 engaged in late 1985. The marriage plans were dropped, however, because of financial problems. Mark was an enrolled agent licensed to do income tax work. He shared an office with another enrolled agent in Santa Clara and did overload work in lieu of rent. Throughout the period in question, he complained of money problems.
In early September 1986, Joe gave Brenda a check for $10,000. The check was immediately funneled to Mark, who thereupon spent the money on a new office in Campbell and paid off certain debts. Shortly thereafter, Joe and Brenda were married in Hawaii. Within days of their return, Brenda began to speak of obtaining a divorce. She complained of Joe’s possessiveness and jealousy. By the middle of October, she told her daughter that one way or another—by death or divorce—the marriage would end and she might then marry Mark.
About a week after they returned from Hawaii, Brenda learned that Joe was using a telephone answering machine to record her conversations. Indeed, even before they were married, Joe had frequently recorded his telephone conversations with Brenda so that, as he explained to his daughter Jolynn, he could later review and analyze them for contradictions. A friend showed Brenda how to unplug the answering machine from the telephone line. Unbeknownst to Brenda, however, the secret taping continued from a voice-activated recorder which Joe had hidden under Jolynn’s bed. The machine recorded every call that came in or out of the house.
On the afternoon of Monday, October 13, 1986, Joe approached his neighbor, Scott Kennedy, a San Jose police officer, and asked him to listen to a particular tape. The tape contained the whispering voices of a man and a woman whom Joe identified as Brenda and Mark. The so-called “whispering tape,” which was played for the jury at trial, begins with Brenda asking, “Why?” and a male voice responding, “Everything was wrong.” The male then refers to a “party across the street,” to “stuff all over the street with the sheets on” which “must have somebody watching,” and to an “accident” on the corner. Brenda then explains, “It’s the garage sale.” The male states, “I tried every possible way,” and asks where Brenda is calling from. When she says “home” the male expresses concern but Brenda reassures him, “I learned how to unplug it.” Later in the conversation the male states, “I got a better plan.” Throughout the call, the male refers to Brenda as “honey” and closes with, “Love you baby.” 3
The various references in the tape place the time of the telephone call at late Saturday night, October 11, when a neighborhood party was occurring; *1094 items from a garage sale that Joe and Brenda held that day were still outside covered with sheets; and an accident which occurred at 11:10 p.m. that evening was not cleared until midnight.
After he talked to Kennedy on Monday, Joe also played the tape for his daughter Jolynn, who lived with Joe and Brenda and worked the night shift as a psychiatric technician at a state hospital. They tried to understand what the conversation meant. Joe told her that it was made Saturday night after he had gone to bed. Jolynn informed her father that she found the door unlocked on Sunday morning when she returned from work; Joe recalled that he had locked the door before going to bed. Concerned about the call, Jolynn asked her father to keep his gun nearby. Joe took her advice, retrieved his gun from a hiding place in the kitchen and placed it in his jacket pocket.
More telephone conversations were recorded the next day, Tuesday, October 14, although it is unclear whether Joe ever heard them. One involved a call from Brenda to Mark. In it Mark asked whether Jolynn was going to work that night; Brenda assured him that she was. Mark then states that he had “picked up a set of wheels to try out and see what it looks like. Trade cars, whatever.” Mark indicated that he would be at the office until 7 p.m. and would be at home until “about 9:30 or so. Any changes, let me know.” The conversation ended with each expressing love for the other. 4
Late that afternoon, Joe and Jolynn left the house for an appointment. Before leaving, Joe handed his daughter an envelope containing his will and asked her to put it in a safe place. The will left Jolynn all of Joe’s property *1095 and gave Brenda one dollar. 5 On their way home, Jolynn told her father that Brenda had been asking about her work schedule. To prevent anything from happening to Joe, they concocted a plan to have Jolynn tell Brenda that she planned to return home early from work that night. Joe also promised that he would confront Brenda the next day, Wednesday. Although when they left the house the doors were locked and the dog was in the yard, when they returned, at 6:45 p.m., they found the doors wide open and the dog running loose in the house.
Alarmed, Joe checked the house with his gun but found nothing. Later, Jolynn mentioned to Brenda that she intended to leave work early that evening. Brenda appeared visibly upset by the news. Jolynn left the house at 7:30 p.m. She did not return home early. When she finally did, her father was dead.
Joe’s death was discovered early the next morning, Wednesday, when Brenda appeared at the doorstep of the Ottos’ neighbor, Scott Kennedy. When Kennedy let her in, she was naked and screaming that “you have to help Joe. I think they have killed him or he’s hurt. Somebody has broken in.” Brenda’s hands were tied behind her back with a terrycloth belt. Kennedy’s wife, Kim, untied her bindings and wrapped Brenda in a blanket; she did not observe any blood or marks on Brenda’s hands or arms, other than what appeared to be a rug burn on her right forearm. Both Kennedys detected the odor of semen.
Brenda explained that she and Joe had fallen asleep while watching television. She awoke with the feeling of “stuff” on her face and the presence of two people hurting Joe. In recounting this tale, Brenda seemed upset but was not crying. The first police officer on the scene obtained a report from Brenda that two Latino men had broken into the home and possibly killed Joe. In a second statement, also at the Kennedy house, Brenda stated that a large Latino man had come out of nowhere and stood next to Joe. She then heard a loud noise and simultaneously felt something sprayed on her face. She tried to run but the intruder struck her on the side of her face. A second man grabbed her housecoat, ripped off her bra, and knocked her into a wrought iron fixture, following which she passed out. She regained consciousness to find her hands tied behind her back and her ankles bound with pantyhose. She eventually untied her feet and went to the Kennedy house.
The officers who entered the Otto residence found Joe dead on the floor of the family room. The lights and television were off. An afghan partially *1096 covered the body. The autopsy disclosed that Joe had died of “massive” head injuries from a “forceful trauma.” The pathologist attributed the injuries to three to five blows to the head. The injuries were consistent with the use of an elongated, blunt instrument, such as a bat, two-by-four or jack handle. There was no evidence of “defensive wounds.”
Once Kennedy informed the police of his conversation with Joe and the existence of the “whispering tape,” the investigation focused on Brenda. A taped interview was conducted, two parts of which were played to the jury. In the first part, Brenda is tearful and describes her marriage as “good,” “not a bad relationship.” In the second part, the interrogating officer informs Brenda about the whispering tape and asks her whether she had ever discussed killing Joe on the phone. After a long pause, Brenda responds, “No—I don’t think so.” Pressed further, Brenda denied the existence of such a discussion. She was arrested that morning. A medical examination revealed no injuries to her face and no evidence that she had been struck. Particles like dried flowers were found on her chest, back and pubic area; these were consistent with dried flowers found on the floor of the murder scene.
The investigation next focused on Mark. In a taped statement he acknowledged that he and Brenda had been lovers, but stated that they had not had sex since September. He claimed that his last telephone conversation with Brenda was Sunday or Monday, when they talked about the deposit on the house they had shared. He stated that he was at his office all day Tuesday until 8 p.m., returned home by 8:45, and worked at home until about midnight; he then took his dog out in his pickup for a run, returning about 1 a.m. He sáw and heard no one. Confronted with the “whispering” conversation, he conceded that it had occurred but could not recall what it was about.
The crime scene investigator noted a number of anomalies. He found no evidence of forced entry into the house, no drawers pulled open, clothes strewn about, mattresses moved or jewelry missing. The victim still had money on him. An expert in blood splatter analysis noted that it was peculiar that Brenda’s pantyhose, robe and bra were found with bloodstains all around them, but none underneath. He also observed that the pattern of blood splatters was inconsistent with Brenda’s account of the attack.
Neither Brenda nor Mark testified at trial.
Discussion
1. Title III—Background
As noted earlier, defendants moved unsuccessfully to suppress the tapes as having been made in violation of Title III. The trial court denied the motion, and the Court of Appeal affirmed the trial court’s ruling.
*1097
Title III provides a “comprehensive scheme for the regulation of wiretapping and electronic surveillance.”
(Gelbard,
v.
United States
(1972)
The exceptions to Title III’s blanket proscription against electronic wiretapping and surveillance are contained in 18 United States Code section 2511(2). Subdivision (d) of that section provides that it shall not be unlawful for a person to intercept a communication where “such person is a party to the communication or where one of the parties to the communication has given prior consent to such interception . . . .” In other words, the Act prohibits third party nonconsensual intercepts; one party may record a conversation without the knowledge or consent of the other, or may authorize another to do so. However, other than duly authorized law enforcement officers, third parties may not engage in nonconsensual surreptitious wiretapping except under extremely limited circumstances not applicable here. (18 U.S.C. § 2511(2).)
The enumerated exceptions define the only circumstances in which surreptitious electronic surveillance is permissible under the Act. “Unless there is a specific section of the statute which excepts a particular interception, all willful interceptions of wire and oral communications are prohibited by the Act.”
(U.S.
v.
Underhill
(6th Cir. 1987)
In addition to imposing a criminal penalty for unauthorized interceptions or disclosure of information obtained through such interceptions (18 U.S.C. § 2511(1)(a)), the Act creates a damage remedy for any person whose wire or oral communications have been unlawfully intercepted, disclosed or used. *1098 (18 U.S.C. § 2520.) More importantly for our purposes here, the Act also provides a suppression sanction. Title 18, United States Code, section 2515 (hereafter section 2515) states: “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.”
Thus, a violation of the federal statute renders the illegally obtained evidence inadmissible in state court proceedings.
(State
v.
Politte
(1982) 136 Ariz.Ct.App. 117 [
The Act also provides the means for invoking the suppression sanction. “Any aggrieved person in any trial, hearing, or proceeding in or before any court. . . of the United States, a State or a political subdivision thereof, may move to suppress the contents of any wire or oral communication intercepted pursuant to this chapter, or evidence derived therefrom, on the grounds that—[SI] (i) the communication was unlawfully intercepted . . . .” (18 U.S.C. § 2518(10)(a).) The Act defines an “aggrieved person” as one “who was a party to any intercepted wire, oral or electronic communication or a person against whom the interception was directed.” (18 U.S.C. § 2510(11).)
As parties to the taped conversations, both defendants here clearly meet the statutory definition of “aggrieved person.” Therefore, defendants had standing to move for suppression pursuant to 18 United States Code section 2518(10).
Furthermore, it is well settled that a telephone conversation is a “wire communication” within the meaning of Title III
(United States
v.
Axselle
(10th Cir. 1979)
A plain reading of the Act, therefore, leads to the inescapable conclusion that defendants’ conversations were unlawfully recorded, and should not have been received in evidence under the strict injunction of Title III. (18 U.S.C. §§ 2515, 2518.)
The Attorney General nevertheless asserts that the conversations were properly admitted under two separate theories: (1) that they were lawfully intercepted under an implied exception to Title III for “interspousal” or “domestic” wiretapping; and (2) that even assuming they were unlawfully obtained, Title III does not compel suppression where the government is merely the innocent recipient, rather than the procurer, of the illegally intercepted communication. We address each of these contentions in turn.
2. Interspousal Wiretapping
The Attorney General’s threshold contention is that the defendants’ conversations were lawfully recorded by the victim under an implied exception to Title Ill’s comprehensive ban on surreptitious wiretapping. In essence, the government contends that Title III does not prohibit a family member from wiretapping a family phone. Because the wiretap here was directed at one spouse by another and was accomplished within the marital home, the Attorney General contends that it was not unlawful and, therefore, that suppression was not required under section 2515.
The Attorney General’s claim runs counter to the plain language of the Act, which states that “any person” who engages in electronic surveillance is liable to punishment or subject to suit "[e]xcept as otherwise specifically *1100 provided,” (18 U.S.C. § 2511(1).) No exception is specifically provided for family members or for interspousal or “domestic” wiretaps. Thus, the government essentially asks this court to create a new, unenumerated exception to the Act for interspousal wiretapping.
That request cannot be squared with the Supreme Court’s pronouncement that, “Except as
expressly
authorized in Title III,
... all
interceptions of wire and oral communications are flatly prohibited.”
(Gelbard
v.
United States, supra,
The plain language and the high court’s pronouncements notwithstanding, the Attorney General contends that the legislative history of Title III reveals a congressional intent to exempt domestic wiretapping from the Act’s comprehensive ban on nonconsensual electronic surveillance. This argument overlooks the settled rule that courts will not refer to extrinsic sources when a statute is clear and unambiguous on its face. (See
Caminetti
v.
United States
(1917)
Even if we look behind the text of the Act, as the government urges, our conclusion remains unaltered. Indeed, contrary to the claims of the Attorney General, the history of Title III reveals an unmistakable congressional intent to prohibit all unauthorized electronic surveillance, including domestic wiretapping.
Congress enacted Title III after extensive legislative hearings had disclosed widespread abuse of electronic surveillance. (See Comment (1977) 27 Buffalo L.Rev. 139, 140, fn. 5.) These abuses were not solely or even primarily occurring in the public sphere, but rather the private domain, particularly in the areas of domestic relations and commercial espionage.
*1101
Appearing before the Senate Judiciary committee, Professor Robert Blakey, widely credited as the author of Title III (see
United States
v.
Giordano, supra,
416 U.S. at pp. 517-518, fn. 7 [40 L.Ed.2d at pp. 354-355]), testified as follows: “[Pjrivate bugging in this country can be divided into two broad categories, commercial espionage and marital litigation.” (Hearings on the Right to Privacy Act of 1967 Before the Subcommittee on Administrative Practice & Procedure of the Senate Judiciary Committee, 90th Cong., 1st Sess., pt. II at p. 413, quoted in
United States
v.
Jones
(6th Cir. 1976)
Numerous statements by other witnesses and legislators during the Senate hearings demonstrate that Congress was keenly aware of the problem of interspousal surveillance. (See Comment,
supra,
27 Buffalo L.Rev. at pp. 142-143; see also Note, (1978) 12 Val. U.L.Rev. 537, 541-542; Comment (1975) 7 U. Tol. L.Rev. 185, 201-205.) As one federal court has observed: “The legislative history [of Title III] abounds with expressions of congressional consensus on the lack of justification for private electronic surveillance, . . .” particularly in the domestic context.
(United States
v.
Jones, supra,
The Senate committee report that accompanied Title III explicitly identified the problem which the legislation was designed to address as the increasingly widespread private surveillance into “each man’s personal, marital, religious, political, or commercial concerns. . . .” (Sen. Rep. No. 1097, 90th Cong., 2d Sess. 225, reprinted in 1968 U.S. Code Cong. & Admin. News, at pp. 2117, 2154, italics added.) Such abuses, the report *1102 continued, could, no longer be condoned. “Virtually all concede that the use of wiretapping or electronic surveillance techniques by private unauthorized, hands has little justification where communications are intercepted without the consent of one of the participants.” (Id. at p. 2156, italics added.) Indeed, a cosponsor of the Act, Senator Hruska, stated that the Act imposes a “broad prohibition ... on private use of electronic surveillance, particularly in domestic relations and industrial espionage situations.” (Id. at p. 2274, italics added.)
Thus, there can be no doubt that Congress was fully aware of the prevalence of domestic wiretapping, and intended to prohibit the practice by virtue of the Act’s comprehensive ban on nonconsensual electronic surveillance. 9 The legal writers who have examined the congressional record are nearly unanimous on this point. As one author observes: “Although Congress made certain specific exclusions from liability under the statutes, it did not specifically exclude spouses. The legislative history leaves no doubt that Title III was designed to prohibit private unauthorized electronic surveillance, and that Congress was aware that a major area for use of such surveillance was the preparation of domestic relations litigation.” (Note (1979) 12 Creighton L.Rev. 1209, 1227.)
Another legal commentator has concluded: “Congress intended that [interspousal surveillance] should be entirely prohibited. This sense of Congress is indicated in the debate, the legislative history, the wording of the statute, and in the opinion of the author of Title III.” (Comment, supra, 7 U. Tol. L.Rev. 185, 203-204.)
These views are widely shared. (See, e.g., Comment, supra, 27 Buffalo L.Rev. at p. 143 [“It can and ought to be inferred . . . that since Congress was aware of the prevalence of wiretapping domestic relations, its failure to exclude this area from the Act’s broad prohibitions was deliberate.”]; Note, supra, 12 Val. U.L.Rev., at p. 539 [“. . . Congress did intend to include interspousal electronic surveillance within the scope of Title III . . . .”]; Comment (1972) 11 Ga.L.Rev. 427, 434 [“The language of Title III is not ambiguous, and the legislative history supports a literal interpretation of the statute’s broad prohibition against interception of oral or wire communications .... The failure of Congress to include interspousal surveillance among the express exceptions to Title III was therefore intentional.”]; but cf. Note (1989) 57 Fordham L.Rev. 1035.)
*1103
In light of the Act’s plain language and equally plain history, the overwhelming majority of courts that have considered the issue have also concluded that Title III’s penalties and prohibitions apply to domestic surveillance.
(Heggy
v.
Heggy
(10th Cir. 1991)
Pritchard v. Pritchard, supra, 132 F.2d 372, is representative of the extensive case law on the subject. After careful consideration of the text, the legislative history, the relevant decisional law and the commentaries, the federal court concluded: “[W]e find that Title HI prohibits all wiretapping activities unless specifically excepted. There is no express exception for instances of willful, unconsented to electronic surveillance between spouses. Nor is there any indication in the statutory language or in the legislative history that Congress intended to imply an exception to facts involving interspousal wiretapping.” (Id. at p. 374.)
United States
v.
Jones, supra,
One federal Court of Appeals has concluded that the Act does not prohibit a spouse from intercepting the telephone conversations of the other spouse. In
Simpson
v.
Simpson
(5th Cir. 1974)
Simpson’s reasoning has been subjected to severe criticism, and its holding has been repudiated by the vast majority of legal commentators and state and federal courts. The leading treatise authors, Professor James G. Carr, *1105 Reporter for the American Bar Association Task Force on Electronic Surveillance, and Clifford Fishman, author of Wiretapping and Eavesdropping (1978), are unanimous in their condemnation. According to Professor Carr, Simpson and its limited progeny “disregard the straightforward legislative framework and unambiguous statutory language . . . .” (Carr, The Law of Electronic Surveillance (2d ed. 1991) § 3.6, p. 3-107.) Fishman observes that “[m]ost courts have rejected Simpson” and explains: “The trend is against the Simpson ‘marital home’ exception, and properly so; even assuming the creation of such an exception would be sound policy, it is clear from the language and history of Title III that Congress intended no such exception.” (Fishman, Wiretapping and Eavesdropping (1991 Supp.) § 25.1, pp. 202-203, fn. omitted.) 11
As noted, the great majority of courts have also rejected
Simpson
v.
Simpson, supra,
As all of these authorities have observed,
Simpson
v.
Simpson, supra,
The
Simpson
court also relied on Title Ill’s so-called “extension phone” exception. The Act excludes from the definition of prohibited intercept devices “any telephone . . . furnished to the subscriber or user by a communications common carrier. . . and being used ... in the ordinary course of its business.” (18 U.S.C. 2510(5)(a).) In explaining this section, one witness at the congressional hearings stated that the Act was not designed to prohibit the casual use of an extension phone to overhear a conversation of a family member.
12
As many have observed, however, there is no evidence that Congress considered systematic wiretapping to represent the use of an extension phone “in the ordinary course of business.”
(United States
v.
Harpel, supra,
The differences between casually overhearing part of a conversation on an extension phone and intentionally wiretapping all incoming and outgoing calls are substantial; the former requires the physical
*1107
presence of the eavesdropper, which inherently limits the extent and frequency of the invasion; the latter, by contrast, requires no supervision, is of potentially unlimited duration, and is wholly indiscriminate.
(Lee
v.
Florida
(1968)
In sum, we follow a majority of the courts in declining to read into Title III an exception for interspousal or domestic wiretapping. Neither the text, the history nor the purposes of Title III permit the conclusion that defendants’ conversations were lawfully intercepted.
3. Private Wiretaps
Having concluded that the tapes were unlawfully procured, we are bound to conclude that their use at trial was erroneous. Section 2515 provides that whenever any wire communication has been intercepted, “no part of the contents of such communication and no evidence derived therefrom may be received in evidence ... if the disclosure of that information would be in violation of this chapter.” As parties to the conversations, defendants were statutorily entitled to suppression on the ground that their communications were “unlawfully intercepted.” (18 U.S.C. § 2518(10)(a)(i).)
The government contends, however, that such a literal reading of Title III would be at variance with the congressional intent; according to the Attorney *1108 General, section 2515 is intended to deter governmental rather than private violations of Title III. Therefore it would be pointless to apply section 2515 where, as here, the government is the innocent recipient, rather than the actual procurer, of the illegally intercepted communications.
Again, the government’s contention does not withstand scrutiny. Where the intent of Congress is expressed in “reasonably plain terms,” a court must ordinarily treat that language as conclusive; no resort to extrinsic aids is necessary or proper.
(Griffin
v.
Oceanic Contractors, Inc.
(1982)
The language of Title III is clear and unambiguous; it provides that no part of the contents of an unlawfully intercepted wire communication may be received in evidence in any proceeding before any state or federal court. (18 U.S.C. §§ 2515, 2518.) The Act draws no distinction between communications unlawfully obtained by the government and those procured unlawfully by private means. Tlius, no further analysis is necessary to demonstrate that the taped conversations were inadmissible under Title III.
The government’s argument also fails on its own terms, however. The legislative intent underlying Title III, and section 2515 in particular, was definitively expounded by the United States Supreme Court in
Gelbard
v.
United States, supra,
The Supreme Court characterized the protection of individual privacy as the “overriding congressional concern.”
(Gelbard
v.
United States, supra,
To remedy the problem of multiple invasions resulting from subsequent disclosures at trial, Congress extended to the victims of illegal wiretaps, private or otherwise, the full panoply of statutory remedies. Chief among these, of course, is the evidentiary prohibition of section 2515, which the high court has characterized as the primary enforcement mechanism of the Act’s strict limitations upon invasions of individual privacy. (Gelbard v. United States, supra, 408 U.S. at pp. 48-50 [33 L.Ed.2d at pp. 187-188].) As the Senate report observed: “ ‘[Section 2515] forms an integral part of the system of limitations designed to protect privacy. Along with the criminal and civil remedies, it should serve to guarantee that the standards of the new chapter will sharply curtail unlawful interception of wire and oral communications.’ ” (1968 U.S. Code Cong. & Admin. News at p. 2185, quoted in Gelbard v. United States, supra, 408 U.S. at pp. 50-51, fn. 9 [33 L.Ed.2d at pp. 188-189].)
Congress was also concerned about the effect on the integrity of the courts of admitting illegally procured evidence. As the high court has explained, the suppression sanction of section 2515 was designed “not only to protect the privacy of communications, but also to ensure that the courts do not become
partners to illegal conduct:
the evidentiary prohibition was enacted also ‘to protect the integrity of court and administrative proceedings.’ ”
(Gelbard
v.
United States, supra,
Contrary to the claims of the Attorney General, therefore, the legislative history of Title III demonstrates that Congress was aware of the problem of private wiretapping and intended to curb its abuse by means of the suppression sanction. Any other conclusion would patently contravene the congressional injunction that “courts ... not become partners to illegal conduct.”
(Gelbard
v.
United States, supra,
Numerous courts, both state and federal, have so concluded. The leading federal case is
U.S.
v.
Vest
(1st Cir. 1987)
A similar conclusion was reached in
United States
v.
Phillips
(8th Cir. 1976)
Several state courts have also concluded that evidence derived from an unlawful private wiretap is inadmissible in a criminal prosecution. In
State
v.
Dwyer
(1978) 120 Ariz.Ct.App. 291 [
*1111
Com.
v.
DeBlase
(1986)
Florida is another state with a wiretap statute modeled on the federal Act.
(Horn
v.
State
(Fla.Dist.Ct.App. 1974)
Concluding that the text and meaning of the statute were plain, the Florida court held that the eavesdropping was unlawful and the contents of the illegally overheard conversation were therefore inadmissible. (Horn v. State, *1112 supra, 298 So.2d at pp. 198-199.) Moreover, because the testimony relative to the intercepted conversation was highly prejudicial, the court was compelled to reverse the judgment and remand for a new trial. (Ibid,.) 17
In sum, neither the text, the history, nor the purposes of Title III support the government’s claim that Congress intended to exempt unlawful private intercepts from the strictures of section 2515. The text of the Act is synonymous with its purpose; we may question the congressional wisdom in adopting so expansive a rule, but we may not, as the Florida Supreme Court observed, “substitute [our] judgment for that of the Legislature and create an exception which would encompass the instant circumstances.”
(State
v.
Walls, supra,
In a related argument, the Attorney General urges that section 2515 be construed as coextensive with the Federal Foiath Amendment exclusionary rule. It is well settled, of course, that the latter applies only to governmental searches; it does not preclude the state from using the fruits of illegal searches and seizures by private citizens.
(United States
v.
Jacobsen
(1984)
Again, the argument does not withstand scrutiny. In
United States
v.
Giordano, supra,
Furthermore, as several courts have observed, “Congress could not have intended the courts to disregard ... the different policy considerations underlying the two rules.”
(U.S.
v.
Vest, supra,
813 F.2d at pp. 481, 483; accord
Horn
v.
State, supra,
In sum, the Fourth Amendment requirement of governmental action has no application to the statutory suppression sanction of section 2515.
Finally, the Attorney General argues that the purpose of the statutory exclusionary rule is simply to sanction the perpetrator of the illegal interception, a limited goal which plainly would not be served here. The government relies on a statement in the Senate report to the effect that “the perpetrator must be denied the fruits of his unlawful actions in civil and criminal proceedings.” (Sen.Rep. 1097,

at p. 69, reprinted in 1968 U.S. Code Cong. & Admin. News at p. 2156.) As discussed above, however, such a narrow reading of the congressional intent does not comport with the Act’s text or legislative history. Congress sought to protect individual privacy by banning all surreptitious wiretapping

Underhill, supra,
In sum, we decline to read into the Act an exception permitting the use of evidence illegally intercepted by a private party. We may question the wisdom of Congress in adopting such a broad-based suppression sanction. We may even urge the Congress to consider an appropriate amendment to the Act which would preclude such a result in future cases. We may not, however, substitute our judgment for that of the legislature. Neither the *1115 contents of the tape recordings nor any evidence derived therefrom was properly admissible in any of the proceedings below. 18
4. Prejudice
The final issue to be resolved is whether the erroneous admission of the taped conversations was so prejudicial as to compel reversal of the judgments of conviction.
A review of the record reveals that the tapes played a critical role in the state’s case against defendants. To be sure, the prosecution adduced substantial independent evidence of motive on the part of both defendants, and cast substantial doubt—based on the physical evidence—on Brenda’s account of the events surrounding the murder. Nevertheless, it is apparent that the tapes themselves constituted the strongest evidence of motive, opportunity, planning and deliberation. The so-called whispering tape provided tangible proof of an ongoing relationship between defendants, and supported the prosecution’s theory that defendants were plotting Joe’s murder at least several days prior to the event. The second tape also shows planning activity by Mark, as he refers to “trad[ing] cars” and inquires of Brenda whether Jolynn, the victim’s daughter, will be working the night of the murder. Although the dialogue is ambiguous and subject to interpretation, there is no doubt that the taped conversations provided the most dramatic and compelling evidence of guilt.
The centrality of the tapes was confirmed by the prosecutor in closing argument. She not only played the “whispering” tape for the jury but displayed an enlarged reproduction of the entire text of the conversation. She ridiculed defense counsel’s suggestion that defendants were simply planning an innocent assignation, stating: “[The] conversations . . . can only reasonably and logically be understood to mean that Brenda and Mark were planning to kill Joe Otto. The evidence shows it, and you know it. And I know it. And the Defendants know it. Anyone who puts those conversations in context knows that they were discussions about killing Joe Otto, period, not setting up a sexual rendezvous or anything else you might be able to stretch your imagination to think of.”
The prosecutor repeatedly adverted to the tapes as concrete evidence of defendants’ deliberate plan to commit murder. Referring to the conversation in which Mark asks Brenda whether Joe’s daughter will be working the night of the murder and makes reference to “trading]” cars, the prosecutor asks: *1116 “Can you reasonably explain away this conversation considering all the evidence as something other than a confirmation that he’s going over to the Otto house later on?. . . . [ft] They have a plan there. And that’s the only person Brenda has a conversation with that night that indicates this sort of action in concert.”
The prosecutor also stressed Brenda’s reaction when first confronted with the tapes, particularly her response when the police asked whether she had ever discussed killing her husband on the telephone: “Does Brenda say, ‘Are you crazy?’ Does she react with outrage? Does she say ‘How dare you suggest such a thing?’ . . . Brenda doesn’t say either of these things, [f] After several seconds, she says, ‘No, I don’t think so.’ And Brenda must have been thinking to herself, ‘My God, did we ever say “kill” on the phone? Didn’t I turn off the tape recorder. Did that S.O.B. have another one some place? What do these people know?’ ”
The tapes, in short, were the linchpin of the state’s case against defendants. Under any standard of error, the conclusion is inescapable that defendants’ convictions must be reversed.
19
We emphasize that reversal is premised solely upon an error of law, rather than insufficiency of the evidence. Accordingly, a retrial is not precluded by the double jeopardy clause.

Notes
Although defendants relied exclusively on federal law at trial, the Court of Appeal also considered defendants' state law claims based on the California Privacy Act (Pen. Code, §§ 631, 632). State law, however, cannot be less protective than the federal Act.

A transcription of the entire conversation, which was introduced at trial, reads as follows: “M—Hello. 1 F—Mark . . . [J] M—Yea. [1] F—Why? 1 M—What happened? [1] F—How *1094 come? ^ M—Everything was wrong ... the party across the street . . . Inaudible . . . (possible . . . Drove up and down a couple of times.) Stuff all over the street with the sheets on . . . uh, you know made the lights brighter. I said, ‘What the hell’s goin’ on, people gonna leave that out there and must have somebody watching or something, I couldn’t figure it out.’ HI F—It’s the garage sale. [5] M—Huh? [1] F—It’s the garage sale. [<jQ M—I know it’s the garage sale. But I couldn’t figure a guy like leaving it out there and not having somebody watching it. . . you know. [5] F—No. [5] M—I tried every way possible. Where you at? [1] F—Home. [5] M—Oh no, you’re calling from the house. [$] F—Yea. I learned how to unplug it. . . [1] M—Huh? [5] F—I learned how to unplug it. [1] M—Oh, you did. Okay, we got to talk, honey. Can you get to me sometime later? [1] F—Yes. [1] M—I’ll be home. I’ll stay home all day. You just get a hold of me, okay? I got a better plan. I’m sorry, honey. Just. . . you know . . . there was no way. Was the accident still on the corner when you guys got home? Huh? [‘J] F—No. [f] M—Was it later? What time did you get home? [1] F—About ten to twelve, [f] M—It just happened over there so ( inaudible). Well, do whatever you have to do to get a hold of me. [1] F—Okay. H] M—Okay. [1] F—Okay. [1] M—Okay. Love you baby. [1] F—Alright. Q] M—Bye, bye.”
The reference on the tape to Mark having “picked up a set of wheels” was given significance by the testimony of a car salesman. Mark had done some bookkeeping for the dealership. The salesman recalled that Mark had borrowed a car from the dealer around Tuesday, October 14, 1986. At the time, Mark already owned two cars in working order.
Joe’s total estate amounted to $300,000.
Like the high court, we occasionally use the general terms “wiretapping” and “electronic surveillance” interchangeably to refer generally to conduct prohibited by the Act. We also use the phrases “domestic” or “spousal” wiretapping with the understanding that the phraseology is imperfect; as here, the target of the snooping usually involves parties other than family members.

stances justifying an expectation of privacy. (18 U.S.C. § 2510(1).) An “oral” communication, on the other hand, is expressly defined as a communication “uttered by a person exhibiting an expectation that such communication is not subject to interception under circumstances justifying such expectation . . . .” (18 U.S.C. § 2510(2); see

Congiess held a number of hearings beginning in 1965 as part of an ongoing legislative effort to revise federal law on electronic surveillance. This process culminated in the enactment of Title III of the Omnibus Crime Control and Safe Streets Act of 1968. (A list of the congressional hearings can be found in Comment, supra, 27 Buffalo L.Rev. at p. 140, fn. 5.)
During the hearings, Senator Long, Chairman of the Subcommittee on Administrative Practice and Procedure of the Senate Judiciary Committee, noted that the three major areas in which private electronic surveillance was widespread were “ ‘(1) industrial (2) divorce cases, and (3) politics. So far, we have heard no real justification for continuance of snooping in these three areas.’ ” (Hearings on Invasion of Privacy Before the Subcommittee on Administrative Practice & Procedure of the Senate Judiciary Committee, 89th Cong., 1st Sess., pt. 5 at p. 2261 (1965-1966), quoted in

The Senate report states that the Act “establishes a blanket prohibition against the interception of any wire communication.” (Sen. Rep. No. 1097, 1968 U.S.Code Cong. & Admin. News, supra, at p. 2180.) Also, the report explains that the definition of “person” in 18 United States Code section 2510(6) “is intended to be comprehensive.” (Id. at p. 2179.)

Professor Robert Blakey, who was instrumental in the passage of Title III, has also repudiated the holding in Simpson. He has written: “Title HI was intended to mean what it says—no surveillance by third parties without a warrant—by cops, spouses ... or any other relevant relations.” (Quoted in Comment, supra, 7 Tol. L.Rev. at p. 203, fn. 85.)
The witness’s statement was as follows: “I take it nobody wants to make it a crime for a father to listen in on his teenage daughter or some such related problem. . . .” (Hearings on the Anti-Crime Program, Before Subcommittee No. 5 of the House Judiciary Com. 90th Cong., 1st Sess., at p. 989 (1967) (testimony of professor Herman Schwartz), quoted in Kratz v. Kratz, supra, 477 F.Supp. at p. 474.)
Professor Carr in his treatise on electronic surveillance has observed that the Act “requires that both the installation and use of the excepted instrument be
normal.”
(Carr,
supra,
The Law of Electronic Surveillance, § 3.2(d)(1), p. 3-42.) Thus, courts must carefully “distinguish between a use which may be justifiably viewed as normal (i.e., an anxious parent’s understandable overhearing of a drug abusing child’s conversations),” and more extensive invasions of privacy represented by systematic electronic surveillance.
(Id.,
§ 3.6, p. 3-110; see
Campiti
v.
Walonis, supra,
One court has held, for example, that an employer might legitimately listen in on an employee’s conversation “in the ordinary course of business” where the employer has particular suspicions about confidential information being disclosed, knows that a particular phone call is with an agent of the competitor, and eavesdrops for only so long as the call involves the type of information he fears is being disclosed.
(Briggs
v.
American Air Filter Co.
(5th Cir. 1980)
One legal writer has examined the legislative history of Title III and concluded that there “is no evidence that any member of Congress ever acknowledged that one of the purposes of the extension phone exception was to allow a father to eavesdrop on his teenage daughter. In fact, the history of Title HI suggests precisely the opposite.” (Comment, supra, 27 Buffalo L.Rev. at p. 149.) We express no view on this question, which is not before us, other than to hold that whatever the scope of the so-called extension phone exception, it provides no authority for an implied domestic wiretap exception to the Act.
The Florida statute 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 state, or a political subdivision thereof, if the disclosure of that information would be in violation of this chapter.”
Two subsequent Florida decisions have reached similar conclusions. In
Nova
v.
State
(Fla.Dist.Ct.App. 1977)
As several courts have concluded, there is strong evidence that Congress intended an exception to the section 2515 exclusionary rule to permit the use of unlawfully intercepted evidence for impeachment purposes.
