CONCURRING AND DISSENTING OPINION
JUSTICE BAER DECIDED: JULY 21, 2020
I join the majority opinion as to Issues One and Three, subject to the clarifications
set forth below. I likewise agree with the majority’s mandate, remanding the case to the
trial court to afford Appellants the opportunity to reassert their challenges to Appellee’s
expert scientific evidence pursuant to Frye v. United States, 293 F. 1013 (D.C. Cir. 1923).
I respectfully dissent, however, from Issue Two, as I agree that Appellee’s experts
engaged in improper extrapolation for the reasons ably set forth by the Chief Justice in
his dissenting opinion.
[J-92A-E-2019] [MO: Donohue, J.] - 4
While I join the majority as to Issue One, I write separately to express my view that
this case involves closer questions as to whether the trial court abused its discretion,
given the analytical gaps identified by the trial court that call into question the methodology
employed by Appellee’s experts, as summarized by the Chief Justice, see id. at 6-10.
Indeed, some of these failings are also detailed in the majority’s recitation of the
Appellants’ experts’ testimony, see Majority Opinion, slip op. at 24-25.
Nevertheless, I ultimately agree with the majority that the trial court abused its
discretion in concluding that Appellee’s experts’ testimonies were inadmissible under Frye
by utilizing its own assessment of the scientific evidence rather than specifically relying
upon Appellants’ experts’ analysis. While a case may involve such a blatant failure of an
expert to apply generally accepted methodologies that a trial court need not rely upon the
opposing party’s expert, trial courts in most cases should be guided by the experts offered
by the parties rather than determining scientific validity on their own, especially
considering the diversity of individual judges’ scientific knowledge. See Grady v. Frito-
Lay, Inc., 839 A.2d 1038, 1045 (Pa. 2003) (recognizing the need for “individual judges,
whose backgrounds in science may vary widely” to be “guided by the consensus that
exists in the scientific community”). Indeed, the risk of trial courts assuming the role of
scientific experts in determining what is “generally accepted” is more pronounced as the
science becomes more complex, as demonstrated by the case at bar. Accordingly, I
conclude that the trial court sub judice abused its discretion and remand is appropriate.
I additionally write to distance myself respectfully from the majority opinion to the
extent it declines to recognize the trial court as “gatekeeper” in Frye challenges. Majority
Opinion, slip op. at 20. As expressed by Judge Beck in Blum v. Merrell Dow
Pharmaceuticals, Inc., 705 A.2d 1314, 1325 (Pa. Super. 1997), aff’d, 764 A.2d 1 (Pa.
2000), “the gatekeeping role of the court, far from detracting from the jury’s function, is in
[J-92A-E-2019] [MO: Donohue, J.] - 5
fact essential to it [as it ensures] that what might appear to the jury to be science is not in
fact speculation in disguise.”
Finally, I join Part II of the Chief Justice’s dissent, addressing this Court’s prior
decision in Betz v. Pneumo Abex LLC, 44 A.3d 27 (Pa. 2012).
