Anderson v. Dakota, Minnesota & Eastern Railroad Corp.

United States District Court, D. Minnesota

November 22, 2016

Daniel J. Anderson, Plaintiff,
v.
Dakota, Minnesota & Eastern Railroad Corporation, Defendant.

          MEMORANDUM AND ORDER

          Paul A. Magnuson United States District Court Judge.

         This matter is before the Court on Defendant's Motion to Exclude Expert Testimony. As stated at the hearing, and for the following reasons, the Motion is denied.

         BACKGROUND

         In August 2012, Plaintiff Daniel Anderson was injured while working for Defendant Dakota, Minnesota & Eastern Railroad (“DM&E”). He was stepping down the ladder on the outside of a railcar when he missed the last step and fell off the car, injuring his ankle. After his fall, two DM&E employees inspected the car and took photographs of the ladder and the sill step, which is the step below the last rung of the ladder. In two of these photographs, the employees included tape measures to show the distance between the sill step and the railcar, and the sill step and the step above it.

         Plaintiff hired Michael O'Brien, a “practicing railroad safety consultant with 47 years of railroad industry experience, ” to analyze these photographs. (Ferguson Aff. Ex. B (O'Brien's Prelim. Report).) He concluded that the tape measure showed a distance to the outside of the sill step that was greater than that allowed by federal safety regulations. He also used the photographs to opine that the area between the step and the rail car (the “clear depth”) was six inches, or two inches less than the minimum depth federal regulations require. O'Brien did not perform any inspection of his own, and thus his opinion that DM&E violated the regulations is based solely on these photographs.

         DISCUSSION

         Expert opinion testimony from a qualified expert is admissible if:

(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of the case.

         Fed. R. Evid. 702. The Court's role is to act as a “gatekeeper” to ensure that only relevant and reliable expert testimony is admitted. Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 589 (1993). To determine reliability, the Court should examine (1) whether the theory or technique can be and has been tested, (2) whether it has been subjected to peer review and publication, (3) the known rate of potential error, and (4) whether the theory or technique has been generally accepted. Id. at 592-95.

         But “the factual basis of an expert opinion goes to the credibility of the testimony, not the admissibility, and it is up to the opposing party to examine the factual basis for the opinion in cross-examination.” Bonner v. ISP Techs., Inc., 259 F.3d 924, 929 (8th Cir. 2001) (citation and quotation omitted). The Court should exclude an expert witness “[o]nly if the expert's opinion is so fundamentally unsupported that it can offer no assistance to the jury.” Id. at 929-30.

         DM&E challenges O'Brien's use of the tape measure in the photos to judge the actual distance of objects in the photo. According to DM&E, O'Brien should have used photogrammetry, which is a mathematical method of determining three-dimensional geometric properties of objects and features through the use of two-dimensional photographs, to determine the true measured distance in the photos.
