Pennsylvania Court Finds that Two Possible Causes Can Prove a Product Malfunction Theory of Liability


This entry was posted by on .

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 →

Pennsylvania Federal Court Excludes Expert Testimony That Tries To Force a Square Peg Into a Round Hole


This entry was posted by on .

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 →

Florida Adopts Daubert Standard for Expert Testimony


This entry was posted by on .

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.

Minnesota “Fryes” the Difference Between Novel Scientific Theory and Novel Science


This entry was posted by on .

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 →

Georgia Court of Appeals Holds Lay Witness Can Provide Opinion Testimony on the Value of a Property If the Witness Had an Opportunity to Form a Reasoned Opinion


This entry was posted by on .

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.
