Instructions
Please review the Admissibility of Expert Testimony in Courts.pdf (check the Supplemental Materials) folder.
This is a bit long 15 page law article but it does a very good job of summarizing the different tests from Frye to Daubert and various hybrid of whether you are qualified to talk about your findings.
Then please provide me a 2 page paper (minimum) summarizing what you have learned. Also do some research – what is the case law in Kentucky? Ohio? Are there differences in state or federal court in both states? Please cite RECENT case law to support your analysis as this law article is out of date.
Why did I assign this?
Knowing what test is adopted in the state is important. Again, it is NOT the tool but the persons knowledge, skill, and whether scientific rigor was followed along with chain of custody and authentication / integrity best practices. Also, when you are leading an investigation you want to be familiar with what test courts (state or federal) may apply!
ADMISSIBILITY OF EXPERT TESTIMONY
IN STATE COURTS
By:
James W. Hunt1
I. INTRODUCTION
Given the technical and engineering complexity involved
in the litigation of aviation lawsuits, the admission and presentation
of testimony by experts in many different disciplines is essential.
This is true for both plaintiffs and defendants, and the battle of
the experts is thus an important part of almost every aviation trial,
particularly one involving product liability issues. The admission of
a defendants expert testimony is crucial to the defense, of course,
but the exclusion or limitation of a plaintiffs expert testimony can
also be a highly effective tool. It is no wonder, then, that litigants
prosecuting or defending aviation lawsuits regularly bringand
vigorously presschallenges to exclude expert testimony under the
jurisdictions applicable evidentiary rules.2 While standards
governing the admissibility of expert testimony are well-settled in
federal courts, state courts often apply different tests for
determining the admissibility of expert testimony. State court
litigants should, therefore, be aware of the evidentiary standard
that will apply to their case.
This article will briefly review the applicable standards
controlling the admission and exclusion of expert testimony in
federal court, and will then survey the current rules in the various
state courts. The guidelines discussed in this article chiefly pertain
to the subject of the reliability of the methodology supporting the

proffered evidence. In addition, the qualifications of the proposed
expert in the pertinent field of expertise, and the relevancy of the
offered evidence to the case need be established by the proponent
of expert evidence. These areas also offer opportunities for
attacking the opponents case by excluding the evidence on grounds
of lack of expert qualification of the witness or lack of relevance of
the testimony to the facts of the case.
II. THE ADMISSIBILITY OF EXPERT TESTIMONY:
FROM Frye TO Daubert
In 1923, the U.S. District Court for the District of
Columbia announced the Frye test, which required a proponent of
scientific evidence to establish that the expert witnesss theory and
method were generally accepted within the relevant scientific
community. Frye v. United States, 293 F. 1013 (D.C. Cir. 1923). In
Frye, the court explained:
Just when a scientific principle or discovery
crosses the line between the experimental and
demonstrable stages is difficult to define.
Somewhere in this twilight zone the evidential
force of the principle must be recognized, and
while courts will go a long way in admitting
expert testimony deduced from a
well-recognized scientific principle or discovery,
the thing from which the deduction is made
must be sufficiently established to have gained
general acceptance in the particular field in
which it belongs.
Frye, 293 F. at 1014. Essentially, the Frye test involves a two-step
analysis: (1) defining the relevant scientific community, and
(2) evaluating the testimony and publications to determine the
existence of a general consensus. At its core, the purpose of the
Frye test is to ensure that the scientific theory or discovery from
3
which an expert derives an opinion is reliable. Hildwin v. State, 951
So. 2d 784 (Fla. 2006).
Although criticized, the Frye test was adopted by many
states and federal courts, remaining the dominant test until 1993,
when the U.S. Supreme Court announced a new standard for
determining the admissibility of scientific evidence in Daubert v.
Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). In Daubert,
the Court reviewed the Frye test in light of sharp divisions among
the courts regarding the proper standard for the admission of
expert testimony and held that Federal Rule of Evidence 702
(FRE 702) superseded the Frye test. Id. at 58587.
Establishing a gate keeping role for the trial judge, the
Daubert Court identified several factors to be considered in
determining the admissibility of scientific evidence. Id. at 592-94.
The Court retained general acceptance within the relevant
scientific community as one factor, but it was no longer the
exclusive test for determining admissibility; additional factors to be
considered include whether the method can and has been tested,
whether it has been subjected to peer review and publication, and
the known or potential error rate. Id. at 593-94. Emphasizing the
new standards flexibility, the Court explained that [i]ts
overarching subject is the scientific validity and thus the evidentiary
relevance and reliability of the principles that underlie a proposed
submission. The focus, of course, must be solely on principles and
methodology, not on the conclusions that they generate. Id. at
59495.
Because the Daubert decision was based on the language
of FRE 702, rather than constitutional grounds, states were not
required to adopt its standard for the admissibility of expert
testimony. Since Daubert, some states have continued to apply Frye,
others have explicitly rejected Frye and adopted the more liberal
Daubert standards or a similar test, and others still have adhered to
their own unique tests.
4
III. A COMPARISON OF STATE APPROACHES
Fourteen states3 and the District of Columbia continue to
apply Frye or a similar test. See Appendix A. State courts applying
Frye have clarified their interpretations of the scope of the test. For
instance, in State v. Gregory, the Washington Supreme Court
explained that [b]oth the scientific theory underlying the evidence
and the technique or methodology used to implement it must be
generally accepted in the scientific community for evidence to be
admissible under Frye. 147 P.3d 1201, 1238 (Wash. 2006). Florida
has explicitly distinguished the methods to be evaluated under Frye
from the conclusions reached using such methods: when the
experts opinion is based upon generally accepted scientific
principles and methodology, it is not necessary that the experts
deductions based thereon and opinion also be generally accepted
as well. U.S. Sugar Corp. v. Henson, 823 So. 2d 104, 109-10 (Fla.
2002). Californias version of the Frye test even permits general
acceptance to be established as a matter of law: Once a
published appellate decision has affirmed admission of a scientific
technique, the techniques general acceptance [is] established as a
matter of law. Further hearings on general acceptance [are]
unnecessary at least until new evidence is presented reflecting a
change in the attitude of the scientific community. People v.
Doolin, 198 P.3d 11, 53 (Cal. 2009) (quoting People v. Kelly, 549 P.2d
1240, 1245 (Cal. 1976)).
3 Because Michigan applies a hybrid test which combines the Frye and Daubert
tests for purposes of determining the admissibility of testimony based on
science, Michigan is included both in the list of states applying Frye and in the
list of states applying Daubert. See Clerc v. Chippewa County War Meml Hosp.,
729 N.W.2d 221, 221 (Mich. 2007) (explaining that the court shall consider all
of the [Daubert] factors listed in MCL 600.2955(1). If applicable, the proponent
must also satisfy the requirement of MCL 600.2955(2) to show that a novel
methodology or form of scientific evidence has achieved general scientific
acceptance among impartial and disinterested experts in the field.).
5
Thirty-five states4 have adopted Daubert or a similar test
that treats the Daubert factors as helpful or instructive. See
Appendix B. States adopting Daubert often observe that their rules
of evidence are essentially identical to the federal rules. See, e.g.,
State v. Brooks, 643 A.2d 226, 229 (Vt. 1993). Other states
acknowledge that the relevant state rule of evidence was amended
explicitly to incorporate Dauberts standards of reliability. Gilbert
v. DaimlerChrysler Corp., 685 N.W.2d 391, 408 (Mich. 2004). Some
states decline to expressly adopt Daubert, but set forth similar
standards. See, e.g., State v. Council, 515 S.E.2d 508 (S.C. 1999).
Others simply acknowledge that Daubert is consistent with their
existing interpretation of their rules of evidence. See, e.g., DiPetrillo
v. Dow Chem. Co., 729 A.2d 677 (R.I. 1999); Nelson v. State, 628
A.2d 69 (Del. 1993); Hutchinson v. Amer. Family Mut. Ins. Co., 514
N.W.2d 882 (Iowa 1994). Even courts that decline to expressly
adopt Daubert often recognize that the Daubert factors are useful to
the trial courts. See, e.g., McDaniel v. CSX Transp., Inc., 955 S.W.2d
257, 265.
Two states, Virginia and Wisconsin, neither follow Frye
nor Daubert, but have instead developed their own unique tests for
determining the admissibility of expert testimony. See Appendix C.
When presented with novel scientific evidence, Virginia vests broad
discretion in the trial court to determine whether the evidence is
so inherently unreliable that a lay jury must be shielded from it, or
whether it is of such character that the jury may safely be left to
determine credibility for itself. Spencer v. Commonwealth, 393
S.E.2d 609, 621 (Va. 1990). Wisconsin, on the other hand, applies a
relevancy test which does not require any reliability determination:
Scientific evidence is admissible under the relevancy test
regardless of the scientific principle that underlies the evidence.
State v. Swope, 762 N.W.2d 725 (Wis. Ct. App. 2008).

IV. CONCLUSION
While federal courts continue to apply the Daubert
standard, state courts vary widely in their tests for determining the
admissibility of expert testimony regarding scientific, technical, or
other specialized knowledge. Due to the importance of expert
testimony to the successful litigation of aviation cases, state court
litigants should remain aware of the jurisdictional standard for
admission of expert testimony that will apply to their case.
Although both Frye and Daubert remain alive and well in state
courts, litigants may still benefit from the advice of Judge Wolff of
the Supreme Court of Missouri:
Forget Frye. Forget Daubert. Read the statute.
Section 490.065 is written, conveniently, in
English. It has 204 words. Those straightforward
statutory words are all you really need to know
about the admissibility of expert testimony in
civil proceedings. Section 490.065 allows expert
opinion testimony where scientific, technical,
or other specialized knowledge will assist the
trier of fact . . . .
