The Courts have struggled with these Rules,
and have examined them by looking at the
forum where the evidence is being provided.
This has led to two distinctly different and
competing ways to analyze such testimony.
The Frye Standard
The first standard comes from Frye v.
United States, 293 F. 1013 (D.C. Cir. 1923), a
case almost a century old discussing the
admissibility ofpolygraphtests as evidence.
The Court in Frye held that expert testimony
must be based on scientific methods that
are sufficiently established and accepted.
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 the courts will
go a long way in admitting experimental
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 acceptancein the particular field in
which it belongs.
States still following Frye include:
California, Illinois, Maryland, Minnesota,
New Jersey, New York, Pennsylvania, and
Washington.

Florida adheres to the Frye standard to
the extent it is procedural in nature.

In
2013, the Florida Legislature passed House
Bill 7015, and Governor Rick Scott signed
it into law. Florida Statutes Chapter 107
(2013) amends Florida’s evidence code to
conform to Rule 702 of the Federal Rules of
Evidence and the principles applicable in
federal court under Daubert v. Merrell Dow
Pharmaceuticals, Inc., 509 U.S. 579 (1993),
with respect to the admissibility of expert
testimony. On February 16, 2017, the Florida
Supreme Court declined to adopt the
Legislature’s “Daubert Amendment” to the
extent such amendment was procedural,
because of “grave concerns about the
constitutionality of the amendment.”

In the remaining states theFrye standard has
been superseded by the Daubertstandard.
The Daubert Standard
The majority of states accept the rule
regarding scientific testing and expert
opinion as provided in Daubert, and the
cases interpreting it; these cases provide
guidelines for determining the admissibility
ofexpert witnesses’testimony. The Daubert
Standard is used by trial courts to make
an initial determination regarding the
admissibility of an expert’s scientific
opinion. The determination rests upon
whether the proposed testimony is
based on reasoning or methodology that
is scientifically valid and can properly
be applied to the facts at issue. The
Daubert factors include: (1) whether the
theory or technique in question can be and
has been tested; (2) whether it has been
subjected to peer review and publication;
(3)its known or potential error rate; (4)the
existence and maintenance of standards
controlling its operation; and (5) whether
it has attracted widespread acceptance
within a relevant scientific community.
“The Daubert Trilogy”
The so-called “Daubert trilogy” refers to
the three U.S. Supreme Court cases that
articulated the Daubert standard.
1. The Daubert case which held that FRE
Rule 702did not incorporate theFrye
“general acceptance” test as the sole
basis for assessing the admissibility
