Minn. Stat. § 626A.10
Within a reasonable time but not later than 90 days after the termination of the period of a warrant or extensions thereof, the issuing or denying judge shall cause to be served, on the persons named in the warrant and the application, and such other parties to intercepted communications as the judge may determine that is in the interest of justice, an inventory which shall include notice of:
On an ex parte showing to a court of competent jurisdiction that there is a need to continue the investigation and that the investigation would be harmed by service of the inventory at this time, service of the inventory required by this subdivision may be postponed for an additional 90-day period.
The contents of any intercepted wire, electronic, or oral communication or evidence derived therefrom shall not be received in evidence otherwise disclosed in any trial, hearing, or other proceeding in a federal or state court unless each party, not less than ten days before the trial, hearing, or proceeding, has been furnished with a copy of the court order, and accompanying application, under which the interception was authorized or approved. This ten-day period may be waived by the judge if the judge finds that it was not possible to furnish the party with the above information ten days before the trial, hearing, or proceeding and that the party will not be prejudiced by the delay in receiving such information.
