The Less Stringent Frye Test is Baaaaack to Determine the Admissibility of Expert Testimony

There are two competing tests for a trial court to determine the admissibility of reliable expert testimony / opinions. One method is known as the Daubert test. The other as the Frye test. Both are named after respective cases. The Daubert test is used in federal court. The Frye test was used in Florida until 2013 when the Florida Legislature modified the evidence code to reflect the application of the Daubert test. The Daubert test is widely considered a more stringent test relative to the admissibility of expert opinions at trial where trial courts perform certain gatekeeper functions to determine the reliability of an expert’s methodology (Check this...

Make Sure Your Expert’s Opinion is Reliable

Posted by David Adelstein

in Uncategorized

I use expert witnesses in many cases. Many. Experts are an important part of cases, particularly complicated disputes where an expert opinion is absolutely warranted. But, as I have discussed in prior articles, an expert's opinion needs to have a foundation of reliability, which is governed by the Daubert standard. Without ensuring that an expert's opinion is reliable, then parties will hire the Joe Blows of the world, pay them a minimal dollar amount, for an outrageous, unsupported, and unqualified opinion. This, of course, provides no value. Hence, the Daubert standard or test "requires that '[t]he testimony is based upon sufficient...

Difference Between Lay Opinion Testimony and Expert Opinion Testimony

Posted by David Adelstein

in Appeal, Evidence, Standard of Review

Although I have numerous blog articles regarding the appellate standard of review when it comes to the admissibility of evidence, it is important to remember that “[a] trial court’s ruling on the admissibility of evidence is reviewed for an abuse of discretion; however, the trial court’s interpretation of the evidence code is reviewed de novo.” L.L. v. The State of Florida, 41 Fla.L.Weekly D854a (Fla. 3d DCA 2016). In L.L., a criminal case, a police officer testified that he smelled the strong odor of marijuana from the defendant and that a plastic bag in defendant’s possession contained marijuana. The defendant objected...

Make Sure to Timely Raise Your Daubert Objection to Expert Testimony

Posted by David Adelstein

in Evidence, Expert Testimony

If you are going to raise a Daubert objection or challenge (or request a Daubert hearing), you need to TIMELY do so before the expert witness testifies. A Daubert motion / challenge / hearing relates to the admissibility of an expert witness’ testimony. As you can imagine, this is an extremely important issue as many cases depend on expert witness testimony to support their burden of proof. In Rojas v. Rodriguez, 41 Fla.L.Weekly D423a (Fla. 3d DCA 2016), a defendant raised a Daubert objection post-verdict. The defendant was challenging the admissibility of the testimony of plaintiff's neurosurgeon expert in requesting a new trial....

Expert Opinion Testimony and the Standard of Appellate Review

Posted by David Adelstein

in Appeal, Expert Testimony, Standard of Review

Previously, I discussed expert opinion testimony and the Daubert gatekeeping test employed by trial courts to determine the admissibility of the expert testimony. But, there is much more to expert opinion testimony. An expert witness is NOT allowed to serve as a conduit for inadmissible hearsay so that a party is using an expert witness to simply get in testimony/evidence that is otherwise inadmissible. Doctors Co. v. State, Dept. of Ins., 940 So.2d 466, 470 (Fla. 1st DCA 2006) (“The rule is well established that if an expert is called merely as a conduit to place inadmissible evidence before the jury, the trial...

Expert Opinion Testimony and Understanding Daubert’s Gatekeeping Test

Posted by David Adelstein

in Evidence, Expert Testimony

Expert opinion testimony is an important aspect of complex civil litigation. Expert testimony assists in proving or disproving liability and damages. A credible and persuasive expert can make the difference in a case and retaining experts, generating expert opinions, and the manner in which expert opinions are presented should not be taken lightly. Regarding expert testimony, Florida Statute s. 90.702 provides: “If scientific, technical, or other specialized knowledge will assist the trier of fact in understanding the evidence or in determining a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify about it in...
