On June 22, 2013, just before midnight, Waterloo police responded to a 911 call. In the process of handling that call, they arrested a woman who had stood on her own front porch for public intoxication, after determining that the woman was drunk. The woman was convicted at a trial of public intoxication.
On appeal, the Iowa Supreme Court reversed the conviction, finding that the front steps and porch of a single family home are not a public place and as such a person cannot be guilty of public intoxication for drinking or being drunk on their single family home’s front porch or steps.
