The Second Department, reversing Supreme Court, determined plaintiff’s motion to set aside the defense verdict in this rear-end collision traffic accident case should have been granted. Although Supreme Court was correct in finding that a Frye hearing was not necessary because biomechanical engineering is an accepted scientific theory, no proper foundation was laid for the defense expert’s (Toosi’s) testimony:
The court properly relied upon a decision of this Court and a decision of the Appellate Term, First Department, in determining that biomechanical engineering is a scientific theory accepted in the field … . …
Separate and distinct from the Frye inquiry is the ” admissibility question applied to all evidence—whether there is a proper foundation—to determine whether the accepted methods were appropriately employed in a particular case'” … . “The question is whether the expert’s opinion sufficiently relates to existing data or is connected to existing data only by the ipse dixit of the expert” … . Here, the defendant failed to establish that Toosi’s opinions related to existing data and were the result of properly applied accepted methodology … . Thus, Toosi’s testimony should have been precluded. Guerra v Ditta, 2020 NY Slip Op 03771, Second Dept 7-8-20
