The Subrogation Strategist

In Rich v. Plumbing No. 1:23-cv-00705-SAG, 2025 U.S. Dist. LEXIS 2263, the United States District Court for the District of Maryland considered two motions for summary judgment, each arguing that the court should exclude the testimony of the plaintiff’s expert. Although the court allowed the plaintiff to file a supplemental brief, it ultimately granted the defendants’ motions for summary judgment. Consequently, the court deemed the testimony of the plaintiff’s one and only expert inadmissible.

The plaintiff, Whitney Rich, on behalf of C.W., brought this action after her ... Continue Reading

In April, the Supreme Court sent a list of proposed amendments to Congress that amend the Federal Rules of Evidence. Absent action by Congress, the rules go into effect December 1, 2023.  The proposed amendments affect Rules 106, 615 and, relevant to this article, 702.

Rule 702 addresses testimony by an expert witness. The proposed rule reads as follows (new material is underlined; matters omitted are lined through):

A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if the proponent demonstrates to the court that it is more likely than not that:

(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 expert’s opinion reflects a reliable application of the principles and methods to the facts of the case.Continue Reading

In Smith v. Spectrum Brands, Inc., 2022 U.S. Dist. LEXIS 142262, the United States District Court for the Eastern District of Pennsylvania (District Court) considered whether the plaintiffs’ liability expert met the requirements of Rule 702 of the Federal Rules of Evidence and could testify that a filter pump for an aquarium tank was defectively designed and caused a fire at the plaintiffs’ home. The defendant filed a motion to exclude the plaintiffs’ liability expert on grounds that the expert’s opinion did not satisfy the reliability element of Rule 702 because the expert never conducted physical testing on the filter pump. The court found that the cognitive testing employed by the expert through various methods, including visual inspections of the evidence, a review of photographs of the scene and literature from the manufacturer, and research on similar products, was sufficiently reliable to admit his opinion.Continue Reading

In Allstate Ins. Co. v. LG Elecs. USA, Inc., No. 19-3529, 2021 U.S. Dist. LEXIS 127014, the United States District Court for the Eastern District of Pennsylvania considered whether plaintiff’s expert engineer’s opinion that there were two possible causes of a fire—both related to alleged product defects within a refrigerator manufactured by the defendant—was sufficient to support the malfunction theory of products liability. The court found that because both potential causes imposed liability on the product manufacturer and the expert ruled out misuse of the product, as well as all external causes of the fire, it was not necessary for the engineer to identify a specific cause under the malfunction theory. The court also found that the expert’s investigation and opinions met the criteria set forth in Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993) and the Federal Rules of Evidence and, thus, were admissible.Continue Reading

In Kenney v. Watts Regulator Co, No. 20-2995, 2021 U.S. Dist. LEXIS 4539 (E.D. Pa. Jan. 11, 2021), the United States District Court for the Eastern District of Pennsylvania considered whether to exclude the plaintiff’s liability expert’s testimony regarding the sufficiency of the defendant’s product maintenance instructions. The plaintiff offered the testimony in support of his failure-to-warn product defect claim. The District Court excluded the testimony because the facts of the case did not support the plaintiff’s failure-to-warn claim, which rendered the testimony irrelevant. This case establishes that expert testimony can be excluded if there is an improper fit between the testimony and the underlying claim.Continue Reading

Seven months ago, the Florida Supreme Court declined to adopt Daubert as the standard for admitting expert testimony in Florida state courts. In DeLisle v. Crane Co., 258 So. 3d 1219 (2018), the court reaffirmed that “Frye, not Daubert, is the appropriate test in Florida.” On May 23, 2019, however, Florida’s high court did an about-face. In In Re: Amendment to the Florida Evidence Code, No. SC19-107, the Florida Supreme Court overruled its decision in DeLisle and declared that Florida will now apply the Daubert standard to determine whether scientific evidence is admissible.Continue Reading

In re 3M Bair Hugger Litig., 2019 Minn. App. LEXIS 11, the Minnesota Court of Appeals analyzed the applicable standard for determining whether or not expert opinion testimony based on a novel scientific theory is admissible. Using the Frye-Mack standard, the court reinforced that if an expert opinion involves a novel scientific theory, the underlying evidence used to formulate that theory must be generally accepted in the relevant scientific community. The court further articulated the standard by confirming that, pursuant to Minn. R. Evid. 702, the Frye-Mack applies to novel scientific theory, not novel science. Once the standard is deemed applicable, the court must find the novel scientific theory to be generally accepted in the scientific community to admit the expert’s testimony. Although 3M does not discuss subrogation matters, its analysis should apply with equal force to opinions offered by experts in subrogation cases.Continue Reading

In DeLisle v. Crane Co., 2018 Fla. LEXIS 1883, 43 Fla. L. Weekly S 459, the Supreme Court of Florida reaffirmed that the appropriate test for admissibility of an expert opinion about new or novel scientific evidence is the “Frye” test, not the “Daubert” test.Continue Reading

In Woodrum v. Ga. Farm Bureau Mut. Ins. Co., 815 S.E.2d 650 (Ga. Ct. App. 2018), the Court of Appeals of Georgia considered whether the lower court properly disqualified a contractor as an expert witness and excluded the contractor from offering lay opinion testimony regarding the value of a property. The Court of Appeals held that, while the lower court properly disqualified the contractor as an expert witness, it improperly excluded the general contractor’s lay opinion testimony regarding the value of the property. This case establishes that, in Georgia, a lay witness can provide opinion testimony on the value of a property if the proponent of the testimony demonstrates that the witness had an opportunity to form a reasoned opinion.Continue Reading
