Wis. Stat. § 823.09
Fourth degree sexual assault under s. 940.225(3m) constitutes lewdness and supports a finding of a nuisance. State v. Panno, 151 Wis. 2d 819, 447 N.W.2d 74 (Ct. App. 1989). Read in conjunction with s. 823.11, ss. 823.09 and 823.10 do not violate due process because they provide the opportunity to challenge prima facie evidence that a defendant knowingly permitted prostitution to occur on his property, and also allow the collateral challenge of the underlying prostitution convictions. The statutes also do not violate constitutional rights to freedom of association, the protection against government establishment of religion, and equal protection. State v. Schultz, 218 Wis. 2d 798, 582 N.W.2d 113 (Ct. App. 1998), 97-3414.
