Wis. Stat. § 227.60

Whenever a suit praying for an interlocutory injunction shall have been begun in a federal district court to restrain any department, board, commission or officer from enforcing or administering any statute or administrative order of this state, or to set aside or enjoin the suit or administrative order, the department, board, commission or officer, or the attorney general, may bring a suit to enforce the statute or order in the circuit court of Dane County at any time before the hearing on the application for an interlocutory injunction in the suit in the federal court. Jurisdiction is hereby conferred upon the circuit court of Dane County and on the court of appeals, on appeal, to entertain the suit with the powers granted in this section. The circuit court shall, when the suit is brought, grant a stay of proceedings by any state department, board, commission or officer under the statute or order pending the determination of the suit in the courts of the state. The circuit court of Dane County upon the bringing of the suit therein shall at once cause a notice thereof, together with a copy of the stay order by it granted, to be sent to the federal district court in which the action was originally begun. An appeal shall be taken within the time period specified in s. 808.04 (2). The appeal shall be given preference.
