Vogel v. Grant-Lafayette Electric Cooperative

The Vogels (plaintiffs), dairy farmers, received electrical service from Grant-Lafayette Electric Cooperative (defendant). After building a new milking facility, their cows began acting strangely and suffering illness; the plaintiffs traced the problem to stray voltage from the defendant's transformer. The cooperative installed an isolator after being notified, and the cows' health improved, but the plaintiffs sued for the harm already caused, alleging negligence and nuisance.

Whether excessive stray voltage that interferes with another's interest in the private use and enjoyment of land constitutes a private nuisance.
