Wis. Stat. § 823.20: Gambling place a public nuisance.

(1) Any gambling place, as defined in s. 945.01 (4) (a), is a public nuisance and may be proceeded against under this chapter.

(2) Any citizen of the county in which such nuisance exists may bring an action, without showing special damages or injury, to enjoin or abate the nuisance. The court after 3 days’ notice to the defendants may allow a temporary injunction without bond. The action shall be dismissed only if the court is satisfied that it should be dismissed on its merits. If application for dismissal is made, the court may continue the action and by order require the attorney general to prosecute it.

(3) If the lessee of the place has been convicted of the crime of commercial gambling because of having operated that place as a gambling place or if such place has been adjudged a nuisance under this chapter, the lease by which such place is held is void and the lessor shall have the same remedies for regaining possession of the premises as the lessor would have against a tenant holding over the tenant’s term.
