Each application for a warrant authorizing or approving the interception of a wire, electronic, or oral communication shall be made in writing upon oath or affirmation to a judge of the district court, of the court of appeals, or of the supreme court and shall state the applicant's authority to make such application. Each application shall include the following information:
The court to whom any such application is made, before issuing any warrant thereon, may examine on oath the person seeking the warrant and any witnesses the person may produce, and must take the person's affidavit or other affidavits in writing, and cause them to be subscribed by the party or parties making the same. The court may also require the applicant to furnish additional documentary evidence or additional oral testimony to satisfy itself of the existence of probable cause for issuance of the warrant.
Upon such application the judge may enter an ex parte order, as requested or as modified, authorizing or approving interception of wire, electronic, or oral communications within the territorial jurisdiction of the court in which the judge is sitting, if the judge determines on the basis of the facts submitted by the applicant that:
Nothing in this chapter is to be considered as modifying in any way the existence or scope of those privileged communications defined in chapter 595. In acting upon an application for a warrant for intercepting communications, the potential contents of any such future communications that are within the provisions of chapter 595 shall not be considered by the court in making its finding as to the probability that material evidence will be obtained by such interception of communications.
Each warrant to intercept communications shall be directed to a law enforcement officer, commanding the officer to hold the recording of all intercepted communications conducted under said warrant in custody subject to the further order of the court issuing the warrant. The warrant shall contain the grounds for its issuance with findings, as to the existence of the matters contained in subdivision 1 and shall also specify:
An order authorizing the interception of a wire, oral, or electronic communication under this chapter must, upon request of the applicant, direct that a provider of wire or electronic communication service, landlord, custodian, or other person shall furnish the applicant immediately all information, facilities, and technical assistance necessary to accomplish the interception unobtrusively and with a minimum of interference with the services that the service provider, landlord, custodian, or person is according the person whose communications are to be intercepted. A provider of wire or electronic communication service, landlord, custodian, or other person furnishing facilities or technical assistance must be compensated by the applicant for reasonable expenses incurred in providing the facilities or assistance.
Denial of an application for a warrant to intercept communications or of an application for renewal of such warrant shall be by written order that shall include a statement as to the offense or offenses designated in the application, the identity of the official applying for the warrant and the name of the law enforcement office or agency.
An interception under this chapter may be conducted in whole or in part by an employee of the state or any subdivision of the state who is an investigative or law enforcement officer authorized to conduct the investigation.
No warrant 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 effective period of any warrant for intercepting communications shall terminate immediately when any person named in the warrant has been charged with an offense specified in the warrant.
Any judge of the district court, of the court of appeals, or of the supreme court may grant extensions of a warrant, but only upon application for an extension made in accordance with subdivision 1 and the court making the findings required by subdivision 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 for longer than 30 days. In addition to satisfying the requirements of subdivision 1, an application for an extension of any warrant for intercepting communications shall also:
Any warrant for intercepting communications under this section, or any order renewing a prior warrant, together with the application made therefor and any supporting papers upon which the application was based, shall be delivered to and retained by the applicant as authority for the interception of communications authorized therein. A true copy of such warrant and the application made therefor shall be retained in the possession of the judge issuing the same, and, in the event of the denial of an application for such a warrant, a true copy of the papers upon which the application was based shall in like manner be retained by the judge denying the same.
Whenever a warrant authorizing interception is entered pursuant to this section, the warrant may require reports to be made to the judge who issued the order showing what progress has been made toward achievement of the authorized objective and the need for continued interception. Such reports shall be made at such intervals as the judge may require.
A warrant for intercepting communications and the application, affidavits, and return prepared in connection therewith, and also any information concerning the application for, the granting of, or the denial of a warrant for intercepting communications shall remain secret and subject to all the penalties of this chapter for unauthorized disclosure to persons not lawfully engaged in preparing and executing such a warrant, unless and until the same shall have been disclosed in a criminal trial or proceeding or shall have been furnished to a defendant pursuant to this chapter.
A warrant for the interception of communications may in all cases be served by any of the officers mentioned in its direction, but by no other person except if the officer requires aid while present and acting in its execution.
The requirements of subdivision 1, clause (2), item (ii), and subdivision 3, clause (4), relating to the specification of the facilities from which, or the place where, the communication is to be interpreted do not apply if:
An interception of a communication under an order with respect to which the requirements of subdivision 1, clause (2), item (ii), and subdivision 3, clause (4), do not apply by reason of subdivision 11 must not begin until the facilities from which, or the place where, the communication is to be intercepted is ascertained by the person implementing the interception order. A provider of wire or electronic communications service that has received an order as provided for in subdivision 11, clause (2), may move the court to modify or quash the order on the ground that its assistance with respect to the interception cannot be performed in a timely or reasonable fashion. The court, upon notice to the attorney applying for the warrant, shall decide a motion expeditiously.
