Adler v. McNeil Consultants, LLC
FILED UNDER SEAL
Plaintiffs Jim S. Adler, P.C. and Jim Adler (collectively “Adler”) move to exclude the expert testimony of Dr. Bernard Jansen. See Dkt. No. 99.
Defendants McNeil Consultants, LLC d/b/a Accident Injury Legal Center Quintessa Marketing, LLC d/b/a Accident Injury Legal Center and Lauren Von McNeil Mingee (collectively “Quintessa”) have filed a response, see Dkt. No. 126, and Adler has filed a reply, see Dkt. No. 137.
In the motion, Adler seeks to exclude Dr. Jansen's rebuttal testimony to the reports of Quintessa's experts David Stewart and Christopher Anderson.
For the reasons explained below, the Court denies Adler's Motion to Exclude Expert Testimony of Dr. Bernard Jansen [Dkt. No. 99]. See Jacked Up, L.L.C. v. Sara Lee Corp., 807 Fed.Appx. 344, 346 n.2 (5th Cir. 2020) ().
The parties and the Court are familiar with the background of this case, so the Court will not repeat it here.
Ramos v. Home Depot Inc., No. 3:20-cv-1768-X, 2022 WL 615023, at *1 (N.D. Tex. Mar. 1, 2022) (cleaned up).
Ramos, 2022 WL 615023, at *1 (cleaned up). And “Daubert's general holding - setting forth the trial judge's general ‘gatekeeping' obligation - applies not only to testimony based on ‘scientific' knowledge, but also to testimony based on ‘technical' and ‘other specialized' knowledge.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 141 (1999).
Applying this analytical framework under Rule 702 and Daubert, a “court may admit proffered expert testimony only if the proponent, who bears the burden of proof, demonstrates that (1) the expert is qualified, (2) the evidence is relevant to the suit, and (3) the evidence is reliable.” Galvez v. KLLM Transp. Servs., LLC, 575 F.Supp.3d 748, 759 (N.D. Tex. 2021).
Aircraft Holding Sols., LLC v. Learjet, Inc., No. 3:18-cv-823-D, 2022 WL 3019795, at *5 (N.D. Tex. July 29, 2022) (cleaned up). “The distinction between lay and expert witness testimony is that lay testimony results from a process of reasoning familiar in everyday life, while expert testimony results from a process of reasoning which can be mastered only by specialists in the field.” Holcombe, 516 F.Supp.3d at 679-80 (cleaned up); accord Arnold v. Allied Van Lines, Inc., No. SA-21-CV-00438-XR, 2022 WL 2392875, at *18 (W.D. Tex. July 1, 2022) (). “A district court should refuse to allow an expert witness to testify if it finds that the witness is not qualified to testify in a particular field or on a given subject.” Aircraft Holding, 2022 WL 3019795, at *5 (cleaned up).
And, if the expert is qualified, Hall v. State, No. CV H-21-1769, 2022 WL 2990912, at *4 (S.D. Tex. July 28, 2022) (cleaned up).
Expert testimony is relevant if it assists the trier of fact in understanding the evidence or determining a fact in issue. Federal Rule of Evidence 401 further clarifies that relevant evidence is evidence that has “any tendency to make a fact more or less probable than it would be without evidence” and “is of consequence in determining the action.”
Id. (cleaned up). “Relevance depends upon whether [the expert's] reasoning or methodology properly can be applied to the facts in issue.” Aircraft Holding, 2022 WL 3019795, at *6 (cleaned up). “To be relevant, the expert's reasoning or methodology [must] be properly applied to the facts in issue.” In re: Taxotere (Docetaxel) Prod. Liab. Litig., 26 F.4th 256, 268 (5th Cir. 2022) (cleaned up).
“When performing [the required gate-keeping Rule 702 and Daubert] analysis, the court's main focus should be on determining whether the expert's opinion will assist the trier of fact.” Puga v. RCX Sols., Inc., 922 F.3d 285, 293 (5th Cir. 2019).
“Assisting the trier of fact means the trial judge ought to insist that a proffered expert bring to the jury more than the lawyers can offer in argument,” but “the helpfulness threshold is low: it is principally ... a matter of relevance.” Id. at 293-94 (cleaned up).
As to reliability, the required “analysis applies to all aspects of an expert's testimony: the methodology, the facts underlying the expert's opinion, the link between the facts and the conclusion, et alia,” and “mandates that expert opinion be grounded in the methods and procedures of science.” Jacked Up, 291 F.Supp.3d at 801 (cleaned up). “Expert evidence that is not reliable at each and every step is not admissible.” Jacked Up, 807 Fed.Appx. at 348 o(cleaned up). “Expert testimony is reliable if the reasoning or methodology underlying the testimony is scientifically valid.” Ramos, 2022 WL 615023, at *1 (cleaned up).
“Such testimony must be more than subjective belief or unsupported speculation.” Id. (cleaned up). “In other words, this Court need not admit testimony that is connected to existing data only by the ipse dixit [- that is, an unproven and unsupported assertion resting only on the authority -] of the expert.” Id. (cleaned up). “[W]ithout more than credentials and a subjective opinion, an expert's testimony that ‘it is so' is not admissible.” Holcombe, 516 F.Supp.3d at 687 (cleaned up).
“Experts are permitted to rely on assumptions when reaching their opinions,” but “those assumptions must have some factual basis in the record and an underlying rationale.” Jacked Up, 291 F.Supp.3d at 807-07 (cleaned up). “But there is no requirement that an expert derive his opinion from firsthand knowledge or observation.” Id. at 801 (cleaned up). More specifically, “[e]xperts are permitted to assume the fact of liability and opine about the extent of damages,” and “[a]n expert's reliance on assumptions does not itself make the expert opinion unreliable or inadmissible.” ENGlobal U.S. Inc. v. Native Am. Servs. Corp., No. CV H-16-2746, 2018 WL 1877015, at *8 (S.D. Tex. Apr. 19, 2018) (cleaned up).
And Federal Rule of Evidence 703 “permit[s] an expert witness to base his opinion on ‘facts or data ... that the expert has been made aware of or personally observed' and to opine [and based his opinion] on inadmissible evidence if ‘experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject.'” Taxotere (Docetaxel) Prod. Liab. Litig., 26 F.4th at 269 & n.10 (cleaned up). More specifically, courts have concluded that, although a party's damages expert “did not personally observe the facts or data in [another expert's report], as a damages expert, he may rely on hearsay, including other expert reports, in forming his opinions.” ENGlobal, 2018 WL 1877015, at *11 (cleaned up).
Still, “Rule 702 and Daubert require an expert witness independently to validate or assess the basis for his or her assumptions,” and “[t]he party seeking to have the district court admit expert testimony must demonstrate that the expert's findings and conclusions are based on the scientific method, and, therefore, are reliable,” which “requires some objective, independent validation of the expert's methodology.” Taxotere (Docetaxel) Prod. Liab. Litig., 26 F.4th at 268 (cleaned up).
“Although the basis of an expert's opinion usually goes to the weight and not the admissibility of expert testimony, in some cases the source upon which an expert's opinion relies is of such little weight that the jury should not be permitted to receive that opinion. In the words of the Third...
