A Pennsylvania judge has declined to impose strict liability on the owner of a cow that entered a Pennsylvania highway and was struck by a man's car, resulting in injury to a passenger, the driver's spouse.

Lawrence County Court of Common Pleas Judge J. Craig Cox's ruling means that William Lefebvre will remain an additional defendant after he and his wife, Janice Lefebvre, sued Frank Bielak, whose cow ventured onto Pennsylvania Route 168 in Hickory Township before colliding with the couple's car.
