The Wisconsin Supreme Court has decided an Illinois-based landscaping company doesn’t have immunity from being sued in the death of a school teacher six years ago. Creekside Tree Service had contracted to trim and remove trees from a youth camp property in Lake Geneva. Sixty-one-year-old teacher Jane Westmas was killed when a tree branch fell on her while she was walking. Creekside argued it was functioning as a technical owner of the property at the time. The state’s high court determined it didn’t qualify for immunity under the law because the company wasn’t an agent of the Conference Point Center youth camp or an occupier of the property.
