Minn. R. Civ. P. 65.01
A temporary restraining order may be granted without written or oral notice to the adverse party or that party's attorney only if (1) it clearly appears from specific facts shown by affidavit or by the verified complaint that immediate and irreparable injury, loss, or damage will result to the applicant before the adverse party or that party's attorney can be heard in opposition, and (2) the applicant's attorney states to the court in writing the efforts, if any, which have been made to give notice or the reasons supporting the claim that notice should not be required. In the event that a temporary restraining order is based upon any affidavit, a copy of such affidavit must be served with the temporary restraining order. In case a temporary restraining order is granted without notice, the motion for a temporary injunction shall be set down for hearing at the earliest practicable time and shall take precedence over all matters except older matters of the same character; and when the motion comes on for hearing, the party who obtained the temporary restraining order shall proceed with the application for a temporary injunction, and, if the party does not do so, the court shall dissolve the temporary restraining order. On written or oral notice to the party who obtained the ex parte temporary restraining order, the adverse party may appear and move its dissolution or modification, and in that event the court shall proceed to hear and determine such motion as expeditiously as the ends of justice require.
