John Loringer (Partner-Milwaukee, WI), Melissa Murphy-Petros (Of Counsel-Chicago, IL) and Brian Del Gatto (Partner-Phoenix, AZ) successfully defended the dismissal of a Canadian manufacturer of farm equipment before the Minnesota Court of Appeals. The plaintiff, a Minnesota dairy farmer, alleged that our client's product was the cause of a decrease in milk production over numerous years. The settlement demand throughout discovery was in excess of $3 million for the loss of production and untimely death of some of the cows. After having the case dismissed at the trial court by demonstrating the lack of foundational reliability with the plaintiff's expert witness theories regarding causation, the plaintiff appealed and the appellate court issued an order affirming dismissal by the trial court and securing a complete victory for the client. The result here solidifies appropriate rules of disclosure for expert opinions.
