In Minnesota, it is legal for a person to record a wire, oral or electronic communication if that person is a party to the communication, or if one of the parties has consented to the recording so long as no criminal or tortious intent accompanies the recording. Minn. Stat. § 626A.02.
Unlawful recordings, or disclosure of their contents when there is reason to know the information was obtained illegally, carry maximum penalties of imprisonment for five years and fines of $20,000. In addition, civil liability for violations statutorily can include three times the amount of actual damages or statutory damages of up to $10,000, as well as punitive damages. Minn. Stat. § 626A.13.
It is a misdemeanor to use any type of device for “observing, photographing, recording, amplifying or broadcasting sounds or events through the window or other aperture of a sleeping room in a hotel, a tanning booth or any other place where a reasonable person would have an expectation of privacy and has exposed or is likely to expose their intimate parts or the clothing covering the immediate area of the intimate parts.” Minn. Stat. § 609.746.
