Recording Law for Recording in Public in Minnesota

Minnesota permits you to intercept and record any wire or electronic communication if you are a party to the communication or have the other party’s prior consent. The same one-party consent rule applies to in-person speech, but only once the statutory definition of "oral communication" is satisfied. That definition, set out in Minn. Stat. § 626A.01, subd. 4, requires the speaker to actually exhibit an expectation that the communication is not subject to interception and that the surrounding circumstances objectively justify that expectation. Minn. Stat. § 626A.02 codifies the one-party consent exception, permitting interception where the person is a party to the communication or one of the parties has given prior consent.

A conversation’s location alone does not determine whether it qualifies as an "oral communication" under Minn. Stat. § 626A.01, subd. 4. That definition requires the speaker to exhibit an expectation that the communication is not subject to interception under circumstances that justify such expectation. A loud argument on a city sidewalk typically will not meet this test because the setting does not justify a privacy expectation, but a hushed conversation in a crowded café corner may, depending on observable cues like lowered voices, deliberate distancing, or an express request for privacy. No Minnesota appellate decision has squarely defined how this test applies to recording devices in public, so the answer turns on the specific facts of each encounter.

Under Minnesota’s wiretap statute (Minn. Stat. ch. 626A), recording on-duty police officers performing official duties in public is not itself illegal. The Eighth Circuit, whose rulings bind Minnesota federal courts, has recognized in dicta that there is a First Amendment right to record police activity in public, reasoning that if recording is protected, so is mere observation (Chestnut v. Wallace, 947 F.3d 1085 (8th Cir. 2020)). However, a later divided panel held that this right was not "clearly established" as of 2015, so officers could still claim qualified immunity in damages suits (Molina v. Book, No. 21-1830 (8th Cir. Feb. 2, 2023)). An older decision, Akins v. Knight (8th Cir. 2017), arose from a non-public-forum police station lobby and is narrower and often treated as an outlier. The upshot is that recording police in public is not barred by Minnesota’s wiretap law, and the Eighth Circuit trend increasingly supports a First Amendment right to do so, but the circuit has been reluctant to treat that right as clearly established for purposes of holding officers liable when they interfere with it. This remains an unsettled area of law.

Minnesota’s wiretap chapter does not regulate silent, video-only recording. Minn. Stat. ch. 626A’s prohibitions and definitions are built entirely around "wire," "electronic," and "oral communication" — i.e., aural or data transmissions — and "intercept" is defined as "aural or other acquisition of the contents" of such a communication. Capturing video without audio therefore falls outside the statute’s scope because the chapter’s coverage hinges on the presence of a communication that includes aural content or data transmission. You may openly film people, police, or incidents in public without their consent as long as you do not record spoken words. This includes live streams and photos taken in public spaces. The only limits come from other laws, such as Minn. Stat. § 609.746 (Interference with Privacy), which criminalizes surreptitious recording in specific private contexts like bathrooms, locker rooms, or through a window into a dwelling.

Minnesota’s voyeurism statute, Minn. Stat. § 609.746, criminalizes surreptitious recording in private contexts such as filming someone in a bathroom, locker room, or changing room, or secretly recording through a window into a dwelling. It also targets secretly recording someone’s intimate body areas. This law does not restrict open recording of public disputes, street-level interactions, or police encounters in public. The key is whether the space and your method suggest you are trying to hide what you are doing; open, non-surreptitious recording in public is not covered. The statute protects the privacy of individuals in private spaces, not the recorder’s own home or public interactions.

Imagine you are walking past a busy intersection when two people begin shouting at each other. One person pulls out a phone and records the exchange. Under Minnesota’s wiretap statute, this recording is likely lawful because the conversation occurred in a public place at a normal volume with no observable steps by the speakers to exclude bystanders, and no party exhibited an expectation of privacy that the circumstances justified. If the same argument happened in a quiet corner of a café with lowered voices, deliberate distancing, or an express request for privacy, the law is less clear. The public setting would not automatically override the speakers’ apparent expectation of privacy; the outcome would depend on the specific facts.

Minnesota’s wiretap statute applies the same one-party consent rule regardless of location. Minn. Stat. § 626A.02 does not include a special carve-out or stricter rule for recording inside one’s own home. The only Minnesota provision that treats "the home" specially is Minn. Stat. § 609.746 (Interference with Privacy), which criminalizes surreptitiously photographing or recording into someone else’s dwelling through a window or aperture, or secretly recording someone in their own home’s bathroom or bedroom-type private space without consent. That statute protects the privacy of a third party being secretly observed in a private space, not the recorder’s own home, and it is not implicated by openly wearing a recording device to document disputes or police interactions.

Minnesota regulates biometric data as a category of "sensitive data" under the Minnesota Consumer Data Privacy Act (MCDPA), Minn. Stat. §§ 325M.10–325M.21 (effective July 31, 2025, with a delayed compliance date for postsecondary institutions). The MCDPA requires controllers to obtain consumers’ consent before processing sensitive data, which includes biometric data used for the purpose of uniquely identifying an individual, and it defines "biometric data" to include a voiceprint. A raw audio recording is not itself "biometric data," but a voiceprint extracted from it to identify the wearer would be, since it is generated to identify a specific individual. The law requires a freely given, specific, informed, and unambiguous consent mechanism and a revocation process that is at least as easy as the mechanism by which consent was given, with processing to cease as soon as practicable but no later than 15 days after receipt of the request. Enforcement is by the Minnesota Attorney General only; there is no private right of action. The MCDPA applies only to entities controlling or processing the personal data of 100,000 or more Minnesota consumers per year (or 25,000+ consumers with more than 25% of gross revenue from data sales), so smaller operations may fall outside its scope.

Minnesota’s ethics rules for lawyers changed in 2002 to align with ABA Formal Opinion 01-422. The Minnesota Lawyers Professional Responsibility Board repealed Opinion No. 18, which had previously condemned undisclosed recording as per se unethical. The Board’s 2002 Comment explains that Minnesota now follows the ABA’s position: undisclosed recording by a lawyer is not per se unethical if the recording is lawful under the applicable consent statute. However, a lawyer who falsely denies recording may violate Rule 4.1 (truthfulness to others) and Rule 8.4(c) (dishonesty/deceit). The Comment also cautions that recording client conversations without disclosure is generally inadvisable, even if not unethical. Minnesota is one of the few states that had adopted the old ABA Formal Opinion 337 rule by name and then affirmatively reversed itself in direct response to ABA Formal Opinion 01-422.

Minnesota’s wiretap statute sets a mixed penalty structure for violations of Minn. Stat. § 626A.02. A general offense can be charged as a felony-level crime with up to $20,000 in fines and up to 5 years imprisonment under Subd. 4(a); certain offenses are gross misdemeanors punishable by up to 364 days under Subd. 4(b)(1); and lesser offenses carry fines up to $500 under Subd. 4(b)(2). The statute also creates a private right of action under Minn. Stat. § 626A.13, so the person you recorded could sue you for damages.
