ALTHOUGH A FRYE HEARING WAS NOT NECESSARY BECAUSE BIOMECHANICAL ENGINEERING IS AN ACCEPTED SCIENTIFIC THEORY, THE BIOMECHANICAL ENGINEER’S TESTIMONY SHOULD NOT HAVE BEEN ADMITTED IN THIS REAR-END COLLISION CASE; NO FOUNDATION WAS LAID FOR THE ENGINEER’S TESTIMONY; PLAINTIFF’S MOTION TO SET ASIDE THE DEFENSE VERDICT SHOULD HAVE BEEN GRANTED (SECOND DEPT).

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
