Opinion

UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF WASHINGTON

JAMES WON, dba TAPIOCA EXPRESS, CASE NO. 2:24-cv-00507-RSL Plaintiffs, v. ORDER DENYING DEFENDANT’S STATE FARM FIRE AND CASUALTY DAUBERT MOTION AND MOTION COMPANY, a foreign company, TO STRIKE

Defendant.

This matter comes before the Court on “Defendant’s Daubert Motion to Exclude Michael Jack and Strike Untimely Expert Report.” Dkt. # 33. Defendant seeks to exclude Mr. Jack’s testimony, alleging that the opinions of Mr. Jack that plaintiff disclosed before the discovery cutoff on October 5, 2025 “are irrelevant and unhelpful to the jury in this case.” Dkts. # 20, # 33 at 1.1 Federal Rule of Evidence 702 provides that expert testimony is admissible if: (1) the witness is sufficiently qualified as an expert by knowledge, skill, experience, training, or education; (2) the scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (3) the testimony is based on sufficient facts

1 This matter can be decided on the papers submitted. Defendant’s request for a Daubert hearing, Dkt. # 33 at 5, is DENIED. ORDER DENYING DEFENDANT’S DAUBERT MOTION AND MOTION TO STRIKE - 1 or data; (4) the testimony is the product of reliable principles and methods; and (5) the expert has reliably applied the relevant principles and methods to the facts of the case. City of Pomona v. SQM N. Am. Corp., 750 F.3d 1036, 1043 (9th Cir. 2014). As construed in Daubert v. Merrell Dow Pharmaceuticals, Inc., Rule 702 tasks a district judge with “ensuring that an expert’s testimony both rests on a reliable foundation and is relevant to the task at hand.” 509 U.S. 579, 597 (1993). Where an expert offers non-scientific testimony, “reliability depends heavily on the knowledge and experience of the expert, rather than the methodology or theory behind” the testimony. Porter v. Martinez, 64 F.4th 1112, 1127 (9th Cir. 2023) (quoting Daubert, 509 U.S. at 594, and Hangarter v. Provident Life & Acc. Ins. Co., 373 F. 3d 998, 1017 (9th Cir. 2004)). The analysis “should be applied with a ‘liberal thrust’ favoring admission.” Messick v. Novartis Pharms. Corp., 747 F.3d 1193, 1196 (9th Cir. 2014) (quoting Daubert, 509 U.S. at 588). Ultimately, the test under Daubert is not the correctness of the expert’s conclusions but the soundness of his methodology. The court is a gatekeeper, not a fact finder. Accordingly, the district court is not tasked with deciding whether the expert is right or wrong, just whether his testimony has substance such that it would be helpful to a jury. If the proposed testimony meets the thresholds of relevance and reliability, its proponent is entitled to have the jury decide upon its credibility, rather than the judge. Challenges that go to the weight of the evidence are within the province of a fact finder, not a trial court judge. A district court should not make credibility determinations that are reserved for the jury. This Court has previously noted that shaky but admissible evidence is to be attacked by cross examination, contrary evidence, and attention to the burden of proof, not exclusion.
