The summer of 2023 brought us more than sunshine and cookouts. Each month this summer, the Supreme Court of Maryland handed down a major decision on Rule 5-702 and the Daubert/Rochkind standard for admissibility of expert testimony. June gave us Abruquah v. State, No. 10 (June 20, 2023). July gave us Oglesby v. Baltimore School Associates, No. 26 (July 26, 2023), and August 31, the last day of the 2022 term, brought us Katz, Abosch, Windesheim, Gershman& Freedman, P.A. v. Parkway Neuroscience and Spine Institute, LLC, No. 30 (Aug. 31, 2023). These opinions join the prior term’s lone high-court decision on the same issue, State v. Matthews, 479 Md. 278 (2022), giving us a total of four post-Rochkind Supreme Court precedents reviewing trial-court applications of the Daubert/Rochkind standard. See Rochkind v. Stevenson, 471 Md. 1 (2020). The 296 combined pages of opinions, concurrences, and dissents from this summer’s trilogy will be cited for decades to come in cases applying Rule 5-702. Each case addressed whether the expert’s challenged opinion had a sufficient factual basis under subsection (3) of Rule 5-702, which includes the inquiry into whether there exists an impermissible analytical gap between the expert’s methodology and conclusion.
