Minn. Stat. § 546.08: CONTINUANCE.

A motion to postpone a trial for the absence of evidence can only be made upon affidavit, stating the evidence expected to be obtained, the reasons for its absence and for expecting that it can be procured, and showing its materiality and that due diligence has been used to procure it; and if the adverse party thereupon admits that such evidence would be given and that it be considered as actually given on the trial, or offered and rejected as improper, the trial shall not be postponed.
