Granting such a motion restores the district court's jurisdiction to consider matters in a postconviction proceeding.See Frisch v. State, 840 N.W.2d 426, 427-28 (Minn. App. 2013) (noting that, after the grant of such a motion, the district court may conduct postconviction proceedings). Minn. Stat. § 590.02, subd. 3 (2016) adds the requirement that such a petition for postconviction proceedings must be "signed by the petitioner or signed by the petitioner's attorney with proof of service on the attorney general and county attorney" when filed.
