Wis. Stat. § 7.21

(a) Bring civil actions to require forfeitures under s. 11.60 for any violation of ch. 11 . Forfeiture actions brought by the county board of election commissioners may concern only violations with respect to reports or statements required by law to be filed with it. The county board of election commissioners may compromise and settle any civil action or potential action brought or authorized to be brought by it under ch. 11 which, in the opinion of the county board of election commissioners, constitutes a minor violation, a violation caused by excusable neglect, or which for other good cause shown, should not in the public interest be prosecuted under such chapter. Notwithstanding s. 778.06 , an action or proposed action authorized under this paragraph may be settled for such sum as may be agreed between the parties. Any settlement made by the county board of election commissioners shall be in such amount as to deprive the alleged violator of any benefit of his or her wrongdoing and may contain a penal component to serve as a deterrent to future violations. In settling actions or proposed actions, the county board of election commissioners shall treat comparable situations in a comparable manner and shall ensure that any settlement bears a reasonable relationship to the severity of the offense or alleged offense. Forfeiture actions brought by the county board of election commissioners shall be brought in the circuit court for the county served by the board of election commissioners.

(b) In the discharge of its authority under par. (a) and upon notice to the party or parties being investigated, subpoena and bring before it any person in the state and require the production of any papers, books or other records relevant to an investigation. A circuit court may by order permit the inspection and copying of the accounts and the depositor's and loan records at any financial institution, as defined in s. 705.01 (3) , doing business in the state to obtain evidence of any violation of ch. 11 upon showing by the county board of election commissioners of probable cause to believe that there is a violation and that such accounts and records may have a substantial relation to the violation. In the discharge of its duties, the county board of election commissioners may cause the deposition of witnesses to be taken in the manner prescribed for taking depositions in civil actions in circuit court.

(c) Delegate to its executive director the authority to issue a subpoena or apply for a search warrant under par. (b) , subject to such limitations as the county board of election commissioners considers appropriate.
