A state appeals court said a judge properly dismissed claims that the founder of the Menards building supply chain owes a woman he once lived with ownership interest in the company.

Debra Sands filed a lawsuit in 2008 alleging she lived with John Menard from 1998 to 2006 and was engaged to him. She claimed that she performed legal work for Menard's company and Menard repeatedly promised to compensate her with an ownership interest. Menard denied making any such promises and has said they were never engaged.

Eau Claire County Circuit Judge Paul Lenz dismissed her claims, finding Sands violated rules that generally prohibit attorneys from acquiring ownership adverse to the client.

The 3rd District Court of Appeals upheld Lenz on Tuesday. Sands' attorney says he disagrees with the ruling and is considering asking the state Supreme Court to take the case.
