Wis. Stat. § 809.71
Comment, 2021
Supervisory writs do not always arise from a pending case through which the parties can be served electronically. A proceeding under this section is a new action that must be served on the respondents by the initiating parties using traditional methods.
A party requesting a supervisory writ under this section must demonstrate that: 1) an appeal is an inadequate remedy; 2) grave hardship or irreparable harm will result; 3) the duty of the trial court is plain, and it acted or intends to act in violation of that duty; and 4) the request for relief is made promptly and speedily. DNR v. Wisconsin Court of Appeals, District IV, 2018 WI 25, 380 Wis. 2d 354, 909 N.W.2d 114, 16-1980. The term "supervisory writ" is both: 1) the general term used in petitioning the court of appeals to exercise its constitutional supervisory authority and in petitioning the supreme court to exercise its constitutional superintending authority; and 2) a new writ the supreme court devised independent of the traditional common law writs. State ex rel. CityDeck Landing LLC v. Circuit Court for Brown County, 2019 WI 15, 385 Wis. 2d 516, 922 N.W.2d 832, 18-0291. When the circuit court in this case ordered the arbitration of a private dispute stayed until the court could decide an insurance coverage dispute, the plaintiff fulfilled all four criteria for the supreme court to issue a supervisory writ under this section.
