Wayne Trask and his minor daughter (plaintiffs) were seriously injured during a hunting trip when Trask’s Winchester Model 94 rifle fell from a tree stand and shot both him and his daughter. The rifle’s hammer, which was in the half-cocked position, had struck a hard object and accidentally discharged. Trask and his daughter, along with his wife (plaintiff), filed a products-liability suit in federal district court against gun manufacturer Olin Corporation (Olin) (defendant), claiming design defect and negligence. During discovery, the plaintiffs sought information from Olin about other incidents involving accidental discharges of the Model 94, regardless of the position of the hammer. The district court granted production of the information over Olin’s objection. Olin moved for the district court to reconsider the order.
