968.31 History History: 1971 c. 40 ss. 92, 93; 1977 c. 272; 1985 a. 297; 1987 a. 399; 1989 a. 56; 1991 a. 294; 1997 a. 283; 2001 a. 109.

968.31 Annotation The testimony of an undercover police officer who was carrying a concealed eavesdropping device under sub. (2) is not the product of the eavesdropping and is admissible even assuming the eavesdropping was unconstitutional. State v. Smith, 72 Wis. 2d 711, 242 N.W.2d 184 (1976).

968.31 Annotation An individual who volunteers to aid the authorities in a lawful, albeit surreptitious, investigation does not commit an injury against the investigated party under sub. (2) (c) simply by participation. Undercover informants must surely realize that evidence they receive may be potentially harmful to the target of the investigation, but this is not the type of injurious act contemplated by the statute. State v. Maloney, 2005 WI 74, 281 Wis. 2d 595, 698 N.W.2d 583, 03-2180.

968.31 Annotation Consent under sub. (2) (b) may be express or implied in fact from surrounding circumstances indicating that the person knowingly agrees to the surveillance. In the prison setting, an inmate has given implied consent to electronic surveillance when the inmate has meaningful notice that a telephone call is subject to monitoring and recording and nonetheless proceeds with the call. State v. Riley, 2005 WI App 203, 287 Wis. 2d 244, 704 N.W.2d 635, 04-2321.

968.31 Annotation If a warrantless intercept complies with sub. (2) (b), commonly referred to as the one-party consent exception, the contents of the intercept may be disclosed in a felony proceeding. The phrase “person acting under color of law” does not exclude law enforcement officers. State v. Ohlinger, 2009 WI App 44, 317 Wis. 2d 445, 767 N.W.2d 336, 08-0135.

968.31 Annotation When determining whether a minor has the capacity to consent to “color-of-law surveillance” under sub. (2) (b), courts should consider the totality of the circumstances to determine whether consent is voluntarily given. The court should consider the minor’s knowledge, intelligence, and maturity. It is also appropriate to consider the minor’s education and state of mind, the demeanor and tone of voice of the officers requesting consent, the location at which consent is given, and the duration of the encounter. The court should also consider the police tactics used to elicit consent and any other relevant circumstances. State v. Turner, 2014 WI App 93, 356 Wis. 2d 759, 854 N.W.2d 865, 13-2101.

968.31 Annotation The use of the “called party control device” by the communications common carrier to trace bomb scares and other harassing telephone calls would not violate any law if used with the consent of the receiving party. 60 Atty. Gen. 90.

968.32 968.32 Forfeiture of contraband devices. Any electronic, mechanical, or other intercepting device used in violation of s. 968.31 (1) may be seized as contraband by any peace officer and forfeited to this state in an action by the department of justice under ch. 778.

968.32 History History: 1979 c. 32 s. 92 (8).

968.33 968.33 Reports concerning intercepted wire or oral communications. In January of each year, the department of justice shall report to the administrative office of the United States courts such information as is required to be filed by 18 USC 2519. A duplicate copy of the reports shall be filed, at the same time, with the office of the director of state courts.

968.33 History History: 1973 c. 12 s. 37; 1977 c. 187 s. 135; Sup. Ct. Order, 88 Wis. 2d xiii (1979).

968.34(1) (1) Except as provided in this section, no person may install or use a pen register or a trap and trace device without first obtaining a court order under s. 968.36 or 18 USC 3123 or 50 USC 1801 to 1811.

968.34(2) (2) The prohibition of sub. (1) does not apply with respect to the use of a pen register or a trap and trace device by a provider of electronic or wire communication service:

968.34(2)(a) (a) Relating to the operation, maintenance and testing of a wire or electronic communication service or to the protection of the rights or property of the provider, or to the protection of users of that service from abuse of service or unlawful use of service;

968.34(2)(b) (b) To record the fact that a wire or electronic communication was initiated or completed in order to protect the provider, another provider furnishing service toward the completion of the wire communication, or a user of that service, from fraudulent, unlawful or abusive use of service; or

968.34(2)(c) (c) Where the consent of the user of that service has been obtained.

968.34(2m) (2m) The prohibition of sub. (1) does not apply to a telephone caller identification service authorized under s. 196.207 (2).

968.34(3) (3) Whoever knowingly violates sub. (1) may be fined not more than $10,000 or imprisoned for not more than 9 months or both.
