Minn. R. Civ. App. P. 143.04
As amended through February 1, 2024
If a public officer dies, resigns or otherwise ceases to hold office during the pendency of an appeal or other appellate proceeding to which the officer is a party in an official capacity, the action does not abate and the successor in office is automatically substituted as a party. Proceedings following the substitution shall be in the name of the substituted party, but any misnomer not affecting the substantial rights of the parties shall be disregarded. An order of substitution may be entered at any time, but the omission to enter such an order shall not affect the substitution.
