968.30 Procedure for interception of wire, electronic or oral communications.
(1) Each application for an order authorizing or approving the interception of a wire, electronic or oral communication shall be made in writing upon oath or affirmation to the court and shall state the applicant’s authority to make the application and may be upon personal knowledge or information and belief. Each application shall include the following information:
(a) The identity of the investigative or law enforcement officer making the application, and the officers authorizing the application.
(b) A full and complete statement of the facts and circumstances relied upon by the applicant, to justify the applicant’s belief that an order should be issued, including:
1. Details of the particular offense that has been, is being, or is about to be committed;
2. A particular description of the nature and location of the facilities from which or the place where the communication is to be intercepted;
3. A particular description of the type of communications sought to be intercepted; and
4. The identity of the person, if known, committing the offense and whose communications are to be intercepted.
(c) A full and complete statement whether or not other investigative procedures have been tried and failed or why they reasonably appear to be unlikely to succeed if tried or to be too dangerous.
(d) A statement of the period of time for which the interception is required to be maintained. If the nature of the investigation is such that the authorization for interception should not automatically terminate when the described type of communication has been obtained, a particular description of facts establishing probable cause to believe that additional communications for the same type will occur thereafter.
(e) A full and complete statement of the facts concerning all previous applications known to the individual authorizing and making the application, made to any court for authorization to intercept, or for approval of interceptions of, wire, electronic or oral communications involving any of the same persons, facilities or places specified in the application, and the action taken by the court on each such application; and
(f) Where the application is for the extension of an order, a statement setting forth the results thus far obtained from the interception, or a reasonable explanation of the failure to obtain such results.
(2) The court may require the applicant to furnish additional testimony or documentary evidence under oath or affirmation in support of the application. Oral testimony shall be reduced to writing.
(3) Upon the application the court may enter an ex parte order, as requested or as modified, authorizing or approving interception of wire, electronic or oral communications, if the court determines on the basis of the facts submitted by the applicant that all of the following exist:
(a) There is probable cause for belief that an individual is committing, has committed, or is about to commit a particular offense enumerated in s. 968.28.
(b) There is probable cause for belief that particular communications concerning that offense will be obtained through such interception.
(c) Other investigative procedures have been tried and have failed or reasonably appear to be unlikely to succeed if tried or to be too dangerous.
(d) There is probable cause for belief that the facilities from which, or the place where, the wire, electronic or oral communications are to be intercepted are being used, or are about to be used, in connection with the commission of the offense, or are leased to, listed in the name of, or commonly used by the person.
(4) Each order authorizing or approving the interception of any wire, electronic or oral communication shall specify:
(a) The identity of the person, if known, whose communications are to be intercepted;
(b) The nature and location of the communications facilities which, or the place where authority to intercept is granted and the means by which such interceptions shall be made;
(c) A particular description of the type of communication sought to be intercepted and a statement of the particular offense to which it relates;
(d) The identity of the agency authorized to intercept the communications and of the person authorizing the application; and
(e) The period of time during which such interception is authorized, including a statement whether or not the interception shall automatically terminate when the described communication has been first obtained.
(5) No order entered under this section may authorize or approve the interception of any wire, electronic or oral communication for any period longer than is necessary to achieve the objective of the authorization, nor in any event longer than 30 days. The 30-day period begins on the earlier of the day on which the investigative or law enforcement officer first begins to conduct an interception under the order or 10 days after the order is entered. Extensions of an order may be granted, but only upon application for an extension made in accordance with sub. (1) and the court making the findings required by sub. (3). The period of extension shall be no longer than the authorizing judge deems necessary to achieve the purposes for which it was granted and in no event be for longer than 30 days. Every order and extension thereof shall contain a provision that the authorization to intercept shall be executed as soon as practicable, shall be conducted in such a way as to minimize the interception of communications not otherwise subject to interception under this chapter, and must terminate upon attainment of the authorized objective, or in any event in 30 days. In the event the intercepted communication is in a code or foreign language, and an expert in that foreign language or code is not reasonably available during the interception period, minimization may be accomplished as soon as practicable after the interception.
(6) Whenever an order authorizing interception is entered pursuant to ss. 968.28 to 968.33, the order may require reports to be made to the court which issued the order showing what progress has been made toward achievement of the authorized objective and the need for continued interception. Such reports sha
