Federal Wiretap Act and ECPA: The Complete Guide (2026)

Federal Wiretap Act and ECPA: The Complete Guide (2026)

Under 18 U.S.C. § 2511(2)(d), federal law permits one-party consent recording: any participant in a conversation may record it without informing the other parties. That default rule applies in all 50 states, but 12 states impose stricter all-party consent requirements that override the federal floor for in-state recordings.

Jurisdiction scope: This article addresses federal US recording law under the Electronic Communications Privacy Act of 1986, Pub. L. 99-508, and its predecessor Title III of the Omnibus Crime Control and Safe Streets Act of 1968, Pub. L. 90-351, as codified at 18 U.S.C. §§ 2510-2523, 2701-2713, and 3121-3127. It does not address state-level recording consent laws in detail; for those, see US recording laws by state.

What the federal law covers (and what it does not)

The Wiretap Act prohibits intentionally intercepting any wire, oral, or electronic communication. Those three categories are defined in 18 U.S.C. § 2510, and understanding them is essential because the statute does not cover everything people casually describe as "recording."

A wire communication is any aural transfer made in whole or in part through the use of facilities for the transmission of communications by the aid of wire, cable, or similar connection, including any electronic storage of such communication (18 U.S.C. § 2510(1)). An oral communication is any oral communication uttered by a person exhibiting an expectation that the communication is not subject to interception under circumstances justifying that expectation (18 U.S.C. § 2510(2)). An electronic communication is any transfer of signs, signals, writing, images, sounds, data, or intelligence of any nature transmitted in whole or in part by a wire, radio, electromagnetic, photoelectronic, or photooptical system, but does not include wire or oral communications (18 U.S.C. § 2510(12)).

Silent video recording is outside the Wiretap Act. This is one of the most commonly misunderstood points in recording law. Because the statute focuses on "aural transfer" for wire communications, and because an "oral communication" requires the utterance of words, a purely visual recording with no audio component is not a "communication" covered by 18 U.S.C. §§ 2510-2523. The constitutional backdrop confirms this: Berger v. New York, 388 U.S. 41 (1967), and Katz v. United States, 389 U.S. 347 (1967), both addressed electronic eavesdropping on conversations, not silent observation. Purely visual surveillance is governed, if at all, by state video-voyeurism statutes and Fourth Amendment doctrine, not by the federal Wiretap Act.

Watch out: Adding audio to a hidden camera changes the legal analysis entirely. A silent doorbell camera is outside the Wiretap Act; the same camera with audio recording active is a potential federal felony if no one in the captured conversation consented.

ECPA's three titles: what each one covers

Congress enacted the Electronic Communications Privacy Act of 1986, Pub. L. 99-508, 100 Stat. 1848, to update the Wiretap Act (originally Title III of the Omnibus Crime Control and Safe Streets Act of 1968, Pub. L. 90-351, 82 Stat. 197) for the digital age. ECPA has three separate titles, each covering a different threat model.

Title I: The Wiretap Act amendments (18 U.S.C. §§ 2510-2523). Title I amended and modernized the 1968 Wiretap Act. It prohibits intercepting communications "in transit," meaning while they are being transmitted. Tapping a phone line while a call is in progress is a Title I violation. Activating a recording device in a room where a conversation is occurring is a Title I violation. The interception must be contemporaneous with the transmission; this is the defining feature that distinguishes Title I from Title II.

Title II: The Stored Communications Act (18 U.S.C. §§ 2701-2713). Title II addresses communications "at rest," meaning stored on a server or device after transmission. Reading someone's stored emails without authorization violates the SCA, not the Wiretap Act. Accessing a cloud storage account, a text message archive, or a voicemail inbox without consent is an SCA violation under 18 U.S.C. § 2701. The distinction between in-transit and at-rest has generated decades of litigation; the courts have generally held that email sitting in an inbox after delivery is stored under the SCA, while email intercepted as it passes through a mail server is a Title I issue.

Title III: Pen Register and Trap-and-Trace (18 U.S.C. §§ 3121-3127). Title III governs devices that capture metadata about communications rather than their content. A pen register captures outgoing dialing, routing, addressing, or signaling information; a trap-and-trace device captures incoming information. Installing either device without a court order is a federal crime under 18 U.S.C. § 3121. The court order standard is lower than for a Title I intercept warrant: law enforcement must certify that the information is relevant to an ongoing criminal investigation, rather than demonstrating probable cause.

Watch out: "Title III" means two different things in this area. ECPA Title III is the pen register and trap-and-trace chapter enacted in 1986. A "Title III warrant" refers instead to Title III of the 1968 Omnibus Crime Control and Safe Streets Act, the original wiretapping law now codified at 18 U.S.C. §§ 2510-2523. When a prosecutor or agent says "Title III," they almost always mean the 1968 super-warrant, not the 1986 metadata chapter.

The § 2511(2)(d) one-party consent rule and the tortious-purpose caveat

The core prohibition is 18 U.S.C. § 2511(1)(a): it is unlawful to intentionally intercept any wire, oral, or electronic communication. Section 2511(2)(d) then carves out the most important private-party exception:

For a section-by-section walkthrough of the core interception statute itself, including its penalties, its exceptions, and the leading cases interpreting it, see our 18 U.S.C. § 2511 explainer.

"It shall not be unlawful under this chapter for a person not acting under color of law to intercept a wire, oral, or electronic 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 unless such communication is intercepted for the purpose of committing any criminal or tortious act in violation of the Constitution or laws of the United States or of any State." 18 U.S.C. § 2511(2)(d)

The practical effect: if you are a participant in a phone call, in-person conversation, or video conference, you may record that communication without informing any other participant. The recording is lawful under federal law even if the other party would object. This is the federal one-party consent default.

The tortious-purpose caveat. The consent exception disappears when the interception is carried out "for the purpose of committing any criminal or tortious act." Courts read that phrase to ask what the interception was for, meaning its intended use, rather than whether the act of recording was itself wrongful. Recording a conversation to gather evidence of workplace harassment is not tortious interception merely because the recording might later be used in litigation against the recorded party. By contrast, recording a business competitor's calls for the purpose of trade-secret theft, or recording a spouse in order to commit extortion, falls squarely within the caveat.

The leading appellate statement is Sussman v. American Broadcasting Companies, 186 F.3d 1200 (9th Cir. 1999), a suit by employees of the Psychic Marketing Group, which ABC investigated by hiring an undercover operative to pose as a psychic telephone advisor and use surveillance devices to "record the activities around her," including conversations she took part in. The Ninth Circuit rejected any reading of the statute that would exempt journalists as a class: "Congress could have drafted the statute so as to exempt all journalists from its coverage, but did not. Instead, it treated journalists just like any other party who tapes conversations surreptitiously." The court was equally clear that a lawful motive does not cure an unlawful one, because "the existence of a lawful purpose does not mean that the interception is not also for a tortious or unlawful purpose."

"Where the taping is legal, but is done for the purpose of facilitating some further impropriety, such as blackmail, section 2511 applies. Where the purpose is not illegal or tortious, but the means are, the victims must seek redress elsewhere." Sussman v. American Broadcasting Cos., 186 F.3d 1200 (9th Cir. 1999)

On those facts the court affirmed judgment for ABC, but on a narrow ground: the plaintiffs had "produced no probative evidence that ABC had an illegal or tortious purpose when it made the tape." The court expressly allowed that the taping "may well have been a tortious invasion of privacy under state law." A recording can therefore survive § 2511 and still expose the recorder to state privacy liability, which is a separate claim under separate law.

One party must actually consent. The statute requires that "one of the parties to the communication" has given consent. A third party who is not part of the conversation cannot authorize the recording. A manager who instructs an employee to record a conversation the manager is not participating in does not satisfy § 2511(2)(d); the employee must themselves be a party.

The Stored Communications Act in brief

The Stored Communications Act, 18 U.S.C. §§ 2701-2713, prohibits intentionally accessing without authorization a facility through which an electronic communication service is provided, and thereby obtaining, altering, or preventing authorized access to a wire or electronic communication in electronic storage (18 U.S.C. § 2701(a)). The SCA is relevant to recording law in several respects.

First, the SCA applies to accessing stored voicemails, text message archives, and email inboxes. Employers who access employees' personal email accounts without consent, estranged spouses who log into a partner's cloud storage, and anyone who uses another person's credentials to read messages all face SCA exposure. Second, the SCA has its own civil remedy: 18 U.S.C. § 2707 provides for actual damages, statutory damages of not less than $1,000, punitive damages, and attorney fees.

Third, the SCA governs government requests to service providers for stored customer data, and this is where the statute's age shows. On its face, 18 U.S.C. § 2703(a) still draws a line at 180 days. A governmental entity may compel a provider to disclose the contents of a communication that has been in electronic storage "for one hundred and eighty days or less" only pursuant to a warrant. Contents that have been in storage "for more than one hundred and eighty days" may be obtained by the means listed in § 2703(b), which include an administrative or grand jury subpoena, or a court order under § 2703(d), neither of which requires the probable-cause showing a warrant does.

That statutory line is not the end of the analysis. In United States v. Warshak, 631 F.3d 266 (6th Cir. 2010), the Sixth Circuit held that "a subscriber enjoys a reasonable expectation of privacy in the contents of emails that are stored with, or sent or received through, a commercial ISP," and that "the government may not compel a commercial ISP to turn over the contents of a subscriber's emails without first obtaining a warrant based on probable cause." The court added that "to the extent that the SCA purports to permit the government to obtain such emails warrantlessly, the SCA is unconstitutional."

Watch out: Do not read the 180-day line as a rule you can plan around. The statutory text and the constitutional analysis point in different directions, Warshak binds only the Sixth Circuit, and what a given provider will hand over on a subpoena versus a warrant is a question of that provider's policy as much as of the statute.

The in-transit versus at-rest line is also contested in modern contexts. Cloud-synchronized messages may be simultaneously in transit and in storage depending on the architecture, and which statute governs can turn on technical details of how a particular service moves and stores them. Courts have not converged on a single answer. Where the classification decides a case, have counsel look at how that specific service actually works rather than assume the label.

Criminal penalties under the Wiretap Act

Violating 18 U.S.C. § 2511 is a federal felony. Section 2511(4)(a) provides that any person who violates the section shall be fined under Title 18 or imprisoned for not more than five years, or both. Each interception is a separate offense for purposes of penalty calculation. That maximum is stated "except as provided in paragraph (b) of this subsection or in subsection (5)," so two exceptions sit in front of it, and neither one reaches an ordinary recording case.

There is no first-offense discount. The current text of § 2511(4)(b) is a narrow satellite carve-out, not a sentencing break for inexperienced defendants. It applies to conduct involving "the interception of a satellite transmission that is not encrypted or scrambled" and transmitted either to a broadcasting station for retransmission to the general public or as an audio subcarrier intended for redistribution to facilities open to the public. It expressly excludes data transmissions and telephone calls, and it drops away entirely where the conduct is "for the purposes of direct or indirect commercial advantage or private financial gain." A first-time offender who records a phone call unlawfully faces the same five-year statutory maximum as anyone else.

Subsection (5) is the other exception, and it is equally beside the point here. Section 2511(5) covers private viewing of unscrambled satellite video transmissions and the interception of unencrypted radio communications on certain frequencies, in each case where the conduct is not for a tortious or illegal purpose and not for direct or indirect commercial advantage or private financial gain. Conduct in that box is routed to a federal civil action rather than to the criminal penalties in § 2511(4)(a): the government is entitled to injunctive relief on a first violation, and a mandatory $500 civil fine follows a repeat violation or violation of an injunction. Recording a phone call or an in-person conversation falls outside it.

The device itself is a separate offense. 18 U.S.C. § 2512 makes it a federal crime to manufacture, assemble, possess, sell, or advertise a device whose design renders it primarily useful for the surreptitious interception of wire, oral, or electronic communications, also punishable by up to five years. Section 2512 does not require that anyone actually intercept a communication, so possession of the equipment can be charged on its own. For the practical side of this, including how to detect and block listening devices and what to do if you find one, see our consumer guide.

Providers face a separate rule about disclosure. Under 18 U.S.C. § 2511(3)(a), a person or entity providing an electronic communication service to the public may not intentionally divulge the contents of a communication while it is in transmission on that service to anyone other than the addressee or intended recipient. Section 2511(3)(b) is the list of exceptions to that bar rather than a penalty provision: a provider may divulge contents as otherwise authorized by § 2511(2)(a) or § 2517, with the lawful consent of the originator or an intended recipient, to a person whose facilities are used to forward the communication, or where the contents were inadvertently obtained and appear to pertain to the commission of a crime, in which case the disclosure may be made to a law enforcement agency.

Civil liability under 18 U.S.C. § 2520

Section 2520 provides a private right of action that makes the Wiretap Act a practical enforcement tool even without federal prosecution. Any person whose wire, oral, or electronic communication is intercepted, disclosed, or intentionally used in violation of the chapter may in a civil action recover from the violator such relief as may be appropriate, including:

• Preliminary, equitable, or declaratory relief as the court deems appropriate (18 U.S.C. § 2520(b)(1));
• Damages under 18 U.S.C. § 2520(b)(2), computed under § 2520(c)(2) as whichever is greater of actual damages plus any profits made by the violator, or statutory damages of whichever is greater of $100 a day for each day of violation or $10,000;
• Punitive damages in appropriate cases (18 U.S.C. § 2520(b)(2)); and
• Reasonable attorney fees and other litigation costs (18 U.S.C. § 2520(b)(3)).

The $10,000 floor per violation is significant in class action litigation. In Bartnicki v. Vopper, 532 U.S. 514 (2001), the Supreme Court addressed whether the First Amendment limited § 2520 liability for a radio broadcaster who aired an intercepted phone call he received from a third party without participating in the interception. The Court held that where a party lawfully obtained a recording of a communication involving a matter of public concern, the First Amendment prohibits imposing liability for disclosing accurately the contents of the communication, even if the original interception was unlawful. Bartnicki does not immunize the original interceptor; it protects only subsequent publishers who played no role in the interception and received the recording lawfully.

California imposes an even higher floor. Cal. Penal Code § 637.2 permits recovery of the greater of $5,000 per violation or three times actual damages, in addition to criminal penalties under Cal. Penal Code § 632.

Exceptions to the Wiretap Act prohibition

Several exceptions authorize interception that would otherwise violate § 2511. The four most frequently encountered are the provider exception, the ordinary-course-of-business exception, the consent exception, and the law-enforcement super-warrant.

Provider exception (18 U.S.C. § 2511(2)(a)(i)). A provider of wire or electronic communication service may intercept, disclose, or use communications in the normal course of providing the service or for the protection of the rights or property of the provider. This authorizes internet service providers and telephone carriers to monitor their networks for abuse, fraud, and security threats. It does not authorize providers to sell communication content to advertisers or to monitor communications outside the scope of service delivery.

Ordinary-course-of-business / extension-phone exception (18 U.S.C. § 2510(5)(a)). The definition of "electronic, mechanical, or other device" in § 2510(5)(a) excludes any telephone or telegraph instrument, equipment, or facility, or any component thereof, that is furnished to a subscriber or user by a provider of wire or electronic communication service in the ordinary course of its business and being used by the subscriber or user in the ordinary course of its business, or that is furnished by such subscriber or user for connection to the facilities of such service and used in the ordinary course of its business.

Watkins v. L.M. Berry & Co., 704 F.2d 577 (11th Cir. 1983), set the limit that matters in practice. The employer there monitored sales calls on a standard extension telephone under a policy employees knew about, and a supervisor listened to a personal call. The Eleventh Circuit held that consent under the statute "is not necessarily an all or nothing proposition; it can be limited," and that the supervisor "was obliged to cease listening as soon as she had determined that the call was personal, regardless of the contents of the legitimately heard conversation." Notice of a monitoring policy buys the employer the first few seconds, not the whole call.

Consent exception (18 U.S.C. § 2511(2)(c) and (d)). Section 2511(2)(c) covers government agents acting under color of law where one party consents; § 2511(2)(d) covers the private-party version described in detail above. Consent may be express or implied. Implied consent exists where circumstances clearly indicate awareness of monitoring; a pre-recorded message at the start of a call stating "this call may be monitored or recorded" generally establishes implied consent for the duration of the call.

Law-enforcement super-warrant (18 U.S.C. §§ 2516-2518). Law enforcement may intercept communications only by obtaining a Title III court order, sometimes called a super-warrant because of its heightened requirements. Under 18 U.S.C. § 2518, the application must:

• Show probable cause to believe an individual is committing, has committed, or is about to commit one of the designated serious offenses listed in 18 U.S.C. § 2516;
• Show probable cause to believe that the communications about the crime will be obtained through the interception;
• Establish that normal investigative procedures have been tried and failed, appear unlikely to succeed, or would be too dangerous (the exhaustion requirement); and
• Describe the facilities or place where the interception is to take place and the type of communications to be intercepted.

A Title III order is limited to 30 days and may be extended only upon fresh application and a judicial finding of necessity. The government must minimize the interception of communications that are not within the scope of the order: agents must immediately stop listening when a communication is clearly not within the authorized categories.

How federal law interacts with stricter state laws

Federal one-party consent under § 2511(2)(d) is a floor, not a ceiling. It sets the minimum permissive standard, and states may be stricter. The statute is built on that assumption. Under 18 U.S.C. § 2516(2), a state's principal prosecuting attorney may apply for a state-court interception order only where a state statute authorizes the application, and the judge may grant it only "in conformity with section 2518 of this chapter and with the applicable State statute." State recording law operates alongside the federal chapter rather than being displaced by it.

Twelve states require the consent of all parties before a private conversation may be recorded: California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Oregon, Pennsylvania, and Washington. For a state-by-state breakdown, see our two-party (all-party) consent states guide.

Three states are miscounted constantly, and all three carry real criminal exposure, so they are worth getting right.

Michigan is not an all-party state. Mich. Comp. Laws § 750.539c reaches a person who "wilfully uses any device to eavesdrop upon" a private conversation without the consent of all parties, and the Michigan Court of Appeals held in Sullivan v. Gray, 117 Mich. App. 476, 324 N.W.2d 58 (1982), that a participant recording their own conversation is not eavesdropping, because eavesdropping means overhearing the discourse of others. That decision drew a dissent, and a federal court applying Michigan law in AFT Michigan v. Project Veritas, 378 F. Supp. 3d 614 (E.D. Mich. 2019), described the protection afforded to participants as "an important, unresolved question of Michigan law." Treat Michigan as unsettled rather than settled in your favor, and see our Michigan recording laws page before relying on it.

Nevada is split by medium. NRS 200.650 prohibits surreptitiously listening to or recording a private conversation "unless authorized to do so by one of the persons engaging in the conversation," which is one-party consent for in-person conversations. Telephone calls are stricter: the Nevada Supreme Court construed NRS 200.620 in Lane v. Allstate Insurance Co., 114 Nev. 1176, 969 P.2d 938 (1998), to prohibit recording a telephone conversation without the consent of both parties. A violation of NRS 200.620 to 200.650 is a category D felony under NRS 200.690. See our Nevada recording laws page for the detail.

Connecticut is on the all-party list, but its rule is also split. The criminal definition in Conn. Gen. Stat. § 53a-187(a)(2) reaches the overhearing or recording of a conversation "without the consent of at least one party thereto, by a person not present thereat," so a participant recording an in-person conversation is outside the criminal offense. Telephone calls are covered separately by the civil statute, Conn. Gen. Stat. § 52-570d, which requires consent of all parties, or a recorded verbal notification at the start of the call, or an automatic tone warning repeated at roughly fifteen-second intervals.

Delaware is worth a note for the opposite reason. It belongs on the all-party list because 11 Del. C. § 1335(a)(4) makes it a crime to intercept "without the consent of all parties thereto a message by telephone, telegraph, letter or other means of communicating privately, including private conversation." A second Delaware statute, 11 Del. C. § 2402(c)(4), mirrors the federal one-party rule almost word for word. The two provisions point in different directions, which is why the cautious reading of Delaware law is the all-party one.

Interstate calls: the cautious rule. When a call crosses state lines and one state requires one-party consent while the other requires all-party consent, the law is not uniform. Courts have generally looked to where the interception device is located, or where the recording party is located, to determine which state's law applies. Because courts in all-party states have sometimes asserted jurisdiction over recordings made by their residents, the cautious rule for interstate calls is to comply with the stricter requirement. A Florida resident recording a call with a New York counterpart should apply Florida's all-party consent rule (Fla. Stat. § 934.03) even though New York only requires one-party consent.

Recording police and the First Amendment

The relationship between the Wiretap Act and the constitutional right to record police officers on duty is one of the most litigated areas in recording law. Several federal circuits have recognized a First Amendment right to record police performing their official duties in public. The First Circuit in Glik v. Cunniffe, 655 F.3d 78 (1st Cir. 2011), held that a man arrested for filming officers on the Boston Common "was exercising clearly-established First Amendment rights in filming the officers in a public space," and that his arrest without probable cause violated clearly established Fourth Amendment rights as well.

The Wiretap Act intersects with this right in states that require all-party consent. Several state prosecutors have attempted to charge citizens recording police encounters under state wiretapping statutes. Courts have largely rejected those prosecutions on First Amendment grounds when the recording was overt and the officer was on duty in a public place.

Illinois is the clearest example of a statute being cut back. The Illinois Supreme Court in People v. Clark, 2014 IL 115776, struck down the state's eavesdropping statute as unconstitutional. The eavesdropping article as it stands today limits the offense in two ways that matter to anyone filming police. First, it reaches only a "private conversation," defined in 720 ILCS 5/14-1(d) as an oral communication that a party "intended to be of a private nature under circumstances reasonably justifying that expectation." Second, 720 ILCS 5/14-2(a)(2) reaches only recording done "in a surreptitious manner." An openly held phone pointed at an officer working in public is a poor fit for both elements.

Watch out: A statute narrowing on paper does not stop an arrest on the street. People are still detained, and phones still seized, over recordings that later turn out to be lawful. Record openly, stay back, do not interfere, and treat the legal question as one you may have to win after the fact rather than at the scene.

Bartnicki v. Vopper, 532 U.S. 514 (2001), provides the Supreme Court's clearest statement on the intersection of the Wiretap Act and the First Amendment. The Court held that where a radio broadcaster obtained a recording of a private conversation involving a matter of public concern and played no role in the original interception, the First Amendment barred liability under the Wiretap Act for broadcasting the recording. Justice Stevens, writing for the Court, reasoned that the broadcaster's right to publish truthful information on matters of public concern outweighed the privacy interest in an already-intercepted communication.

Employer recording and the ordinary-course exception

Employers occupy a particular position under the Wiretap Act because they commonly operate the communications infrastructure employees use. The ordinary-course-of-business exception at 18 U.S.C. § 2510(5)(a) permits monitoring of business lines for legitimate business purposes. Four conditions courts have identified to qualify for the exception:

1. The employer uses telephone equipment provided in the ordinary course of business, not a separate recording device attached to the line;
2. The monitoring is for a legitimate business purpose (call quality, training, regulatory compliance);
3. Employees have been given advance notice that calls may be monitored; and
4. The employer stops monitoring as soon as the call is identified as personal, per Watkins.

Three states impose statutory advance-notice requirements beyond the Wiretap Act's baseline. Conn. Gen. Stat. § 31-48d requires employers engaged in electronic monitoring to give prior notice to employees, subject to exceptions, and carries a civil penalty. Del. Code tit. 19, § 705 bars a Delaware employer from monitoring or intercepting an employee's telephone, email, or internet usage unless it either provides an electronic notice each day the employee accesses the employer's email or internet service, or gives a one-time written notice the employee acknowledges; violations carry a $100 civil penalty per violation. New York requires notice under N.Y. Civ. Rights Law § 52-c, effective May 7, 2022. For a detailed treatment of employer monitoring rules, see our employer recording guide.

Deepfakes and the TAKE IT DOWN Act: a separate federal layer

The TAKE IT DOWN Act, Pub. L. 119-12, 139 Stat. 55, was signed on May 19, 2025. Its full name is the Tools to Address Known Exploitation by Immobilizing Technological Deepfakes on Websites and Networks Act. It creates a distinct federal criminal prohibition on publishing nonconsensual intimate visual depictions, including AI-generated deepfakes depicting real individuals, and requires covered platforms to remove flagged content.

The TAKE IT DOWN Act does not amend or interact with the Wiretap Act or the Stored Communications Act. It addresses a different harm (unauthorized publication of intimate images) through a different mechanism (platform takedown obligations and criminal penalties for publishers). A recording of a conversation that is also sexual in nature may trigger both statutes if it is published without consent, but the two statutes are analytically independent.

Constitutional backdrop: Katz, Berger, and Carpenter

The Wiretap Act's prohibition reflects Fourth Amendment principles articulated in Katz v. United States, 389 U.S. 347 (1967). In Katz, the Supreme Court held that "because the Fourth Amendment protects people rather than places, its reach cannot turn on the presence or absence of a physical intrusion into any given enclosure," and that FBI agents who attached a listening device to the outside of a public telephone booth had conducted a search. Justice Harlan's influential concurrence articulated the two-part test: the person exhibited a subjective expectation of privacy, and that expectation is one society recognizes as reasonable. Katz displaced the trespass doctrine of Olmstead v. United States, 277 U.S. 438 (1928).

Berger v. New York, 388 U.S. 41 (1967), decided the same term, struck down New York's eavesdropping statute because it gave officers "a roving commission" to seize any and all conversations, permitted a two-month authorization on a single showing of probable cause, and set no termination point once the conversation sought was seized. Those defects map almost point for point onto the requirements Congress later wrote into 18 U.S.C. § 2518.

The modern chapter is Carpenter v. United States, 585 U.S. 296 (2018), and it belongs here because it is about exactly the data the Stored Communications Act governs. Investigators used SCA court orders to obtain 12,898 cell-site location points covering 127 days of one suspect's movements. The Court held that acquiring those records was a Fourth Amendment search, declining to extend the third-party doctrine of Smith v. Maryland and United States v. Miller to cell-site records, because historical location records "give the Government near perfect surveillance" and let it "travel back in time to retrace a person's whereabouts." Carpenter did not rewrite the SCA, but it is the reason a § 2703(d) order is no longer a safe assumption for sensitive categories of provider-held data.

Together, these cases establish that electronic surveillance requires constitutional justification; Congress codified that requirement in the Wiretap Act's super-warrant provisions. The private-party one-party consent rule in § 2511(2)(d) reflects the corollary principle: no reasonable expectation of privacy attaches to communications in which the other party might reveal the contents.

Disclaimer

This article provides general legal information about the federal Wiretap Act (18 U.S.C. §§ 2510-2523), the Stored Communications Act (18 U.S.C. §§ 2701-2713), and related ECPA provisions, as verified on 2026-08-04.
