Expert Testimony -- 2017



O'Banion v. Ford Motor Co.   (Indiana Supreme Court)

Expert witness standard in Indiana

The NAM filed an amicus brief in the Indiana Supreme Court supporting Ford Motor Company in a suit regarding Indiana’s evidentiary rules of expert testimony. This litigation stems from an Indiana Court of Appeals holding that applied higher standards to expert scientific testimony as compared to engineering or other highly technical knowledge. This is important because jurors place significant weight on expert testimony; therefore, engineering or other highly technical testimony should be subject to the same standards. The NAM’s brief argued that Indiana courts should follow the majority of state courts in ensuring that engineering testimony is “based on reliable principles” before the testimony is presented to a jury. The court did not agree with the majority approach but followed the minority in allowing an engineer’s testimony to reach the jury.
