5 UNITED STATES DISTRICT COURT WESTERN DISTRICT OF WASHINGTON 6 AT SEATTLE 7 8 NATHAN CAMPOS, et al., Case No. C22-1806-RSM Plaintiffs, ORDER GRANTING MOTION TO 9 EXCLUDE EXPERT MUHAMMAD v. KAHN 10 BIG FISH GAMES, a Washington corporation, 11 et al., 12 Defendants.
13 This matter comes before the Court on Defendants’ Motion to Exclude the Expert 14 Testimony of Muhammad Khan, Dkts. #177 and #183 (sealed). Plaintiffs oppose the Motion. 15 Dkt. #194. The Court has determined that it can rule without oral argument. 16 Federal Rule of Evidence 702 provides that a witness who is qualified as an expert by 17 knowledge, skill, experience, training, or education may testify in the form of an opinion or 18 otherwise if: 19 (a) the expert’s scientific, technical, or other specialized knowledge 20 will help the trier of fact to understand the evidence or to determine a fact in issue; 21 (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; 22 and (d) the expert has reliably applied the principles and methods to the 23 facts of the case. 24 1 Under Rule 702, the trial court acts as a gatekeeper and ensures that the proffered scientific testimony meets certain standards of both relevance and reliability before it is admitted. See 2 Daubert v. Merrell Dow Pharm., Inc. (“Daubert I”), 509 U.S. 579, 590 (1993). The party 3 proffering expert testimony has the burden of showing the admissibility of the testimony of a 4 preponderance of the evidence. See id. at 592 n.10. “[J]udges are entitled to broad discretion 5 when discharging their gatekeeping function” related to the admission of expert testimony. 6 United States v. Hankey, 203 F.3d 1160, 1168 (9th Cir. 2000) (citing Kumho Tire Co. v. 7 Carmichael, 526 U.S. 137, 150-53 (1999)). The Court considers four factors to determine if 8 expert testimony will assist the trier of fact: “(i) whether the expert is qualified; (ii) whether the 9 subject matter of the testimony is proper for the jury’s consideration; (iii) whether the testimony 10 conforms to a generally accepted explanatory theory; and (iv) whether the probative value of the 11 testimony outweighs its prejudicial effect.” Scott v. Ross, 140 F.3d 1275, 1285-86 (9th Cir. 12 1998). 13 As an initial matter, the Court must determine whether a witness is qualified as an expert 14 by “knowledge, skill, experience, training or education.” Fed. R. Evid. 702. Because the Rule 15 “contemplates a broad conception of expert qualifications,” only a “minimal foundation of 16 knowledge, skill, and experience” is required. Hangarter v. Provident Life & Accident Ins. Co., 17 373 F.3d 998, 1015-16 (9th Cir. 2004) (emphasis in original) (quoting Thomas v. Newton Int’l 18 Enters., 42 F.3d 1266, 1269 (9th Cir. 1994)). A “lack of particularized expertise goes to the 19 weight of [the] testimony, not its admissibility.” United States v. Garcia, 7 F.3d 885, 890 (9th 20 Cir. 1993) (citing United States v. Little, 753 F.2d 1420, 1445 (9th Cir. 1984)); see also Daubert 21 v. Merrell Dow Pharm., Inc. (“Daubert II”), 43 F.3d 1311, 1315 (9th Cir. 1995). 22 The trial court must also ensure that the proffered expert testimony is reliable. Generally, 23 to satisfy Rule 702’s reliability requirement, “the party presenting the expert must show that the 24 1 expert’s findings are based on sound science, and this will require some objective, independent validation of the expert’s methodology.” Daubert II, 43 F.3d at 1316. Toward this end, the 2 Supreme Court in Daubert I set forth the following factors for the trial court to consider when 3 assessing the reliability of proffered expert testimony: (1) whether the expert’s method, theory, 4 or technique is generally accepted within the relevant scientific community; (2) whether the 5 method, theory, or technique can be (and has been) tested; (3) whether the method, theory, or 6 technique has been subjected to peer review and publication; and (4) the known or potential rate 7 of error of the method, theory, or technique. See Daubert I, 509 U.S. at 593-94. An expert 8 opinion is reliable if it is based on proper methods and procedures rather than “subjective belief 9 or unsupported speculation.” Id. at 590. The test for reliability “‘is not the correctness of the 10 expert’s conclusions but the soundness of his methodology.’” Stilwell v. Smith & Nephew, Inc., 11 482 F.3d 1187, 1192 (9th Cir. 2007) (quoting Daubert II, 43 F.3d at 1318). 12 Alternative or opposing opinions or tests do not “preclude the admission of the expert’s 13 testimony – they go to the weight, not the admissibility.” Kennedy v. Collagen Corp., 161 F.3d 14 1226, 1231 (9th Cir. 1998). Furthermore, “‘[d]isputes as to the strength of [an expert’s] 15 credentials, faults in his use of [a particular] methodology, or lack of textual authority for his 16 opinion, go to the weight, not the admissibility, of his testimony.’” Id. (quoting McCullock v. 17 H.B. Fuller Co., 61 F.3d 1038, 1044 (2d Cir. 1995)). 18 Finally, the Court must ensure that the proffered expert testimony is relevant. As 19 articulated in Rule 702, expert testimony is relevant if it assists the trier of fact in understanding 20 evidence or in determining a fact in issue. See Daubert I, 509 U.S. at 591. Thus, the party 21 proffering such evidence must demonstrate a valid scientific connection or “fit” between the 22 evidence and an issue in the case. See id. Expert testimony is inadmissible if it concerns factual 23 issues within the knowledge and experience of ordinary lay people because it would not assist 24 1 the trier of fact in analyzing the evidence. In the Ninth Circuit, “[t]he general test regarding the admissibility of expert testimony is whether the jury can receive ‘appreciable help’ from such 2 testimony.” United States v. Gwaltney, 790 F.2d 1378, 1381 (9th Cir. 1986). Because unreliable 3 and unfairly prejudicial expert witness testimony is not helpful to the trier of fact, the trial court 4 should exclude such evidence. See Jinro Am., Inc. v. Secure Invs., Inc., 266 F.3d 993, 1004 (9th 5 Cir. 2001). Likewise, expert testimony that merely tells the jury what result to reach is 6 inadmissible. See Fed. R. Evid. 704, Advisory Committee Note (1972); see also, e.g., United 7 States v. Duncan, 42 F.3d 97, 101 (2d Cir.

Secure Invs., Inc., 266 F.3d 993, 1004 (9th 5 Cir. 2001). Likewise, expert testimony that merely tells the jury what result to reach is 6 inadmissible. See Fed. R. Evid. 704, Advisory Committee Note (1972); see also, e.g., United 7 States v. Duncan, 42 F.3d 97, 101 (2d Cir. 1994) (“When an expert undertakes to tell the jury 8 what result to reach, this does not aid the jury in making a decision, but rather attempts to 9 substitute the expert’s judgment for the jury’s.”). 10 First, Defendants challenge Khan’s qualifications as an expert opining on damages 11 models in this case. Dkt. #177 at 3-5. Plaintiffs contend that Kahn “is undoubtedly qualified as 12 a financial analyst and accountant” to provide an expert opinion for the “very limited purpose[]” 13 on “whether certain damages models . . . can be measured for class members using Defendants’ 14 financial data.” Dkt. #194 at 2. 15 Khan’s CV indicates that he has a Secondary School Certificate, a “Higher” School 16 Certificate, and accounting certifications and charters, and he has years of experience as a 17 financial analyst in banking and real estate. Dkt. #163. His declaration states that he has “over 18 20 years of experience as a financial analyst” and is “currently the Head of Investment at Building 19 Communities Initiative, a real estate developer located in Australia.” Id. at ¶¶ 2-3. For his work, 20 he analyzes investment opportunities for hotels, resorts, and government affordable housing 21 projects,” and he has prior experience with investment banks doing “comprehensive financial 22 analysis in a variety of industries.” Id. at ¶ 3. He has provided expert testimony in two prior 23 24 1 cases, which involved banking and real estate under Islamic law. Id. at ¶ 5; Dkt. #177 at 3 (citing Khan deposition). 2 The Court agrees with Defendants. Plaintiffs offer no evidence of specific training, 3 experience, or specialized knowledge Khan has that is relevant to his damages models 4 examination in this case. Merely stating that Kahn is “undoubtedly qualified” because he works 5 as a “financial analyst and accountant” is conclusory and insufficient to qualify Khan as an expert 6 witness. See Myrick v. U.S. Saws, Inc., No. C11-1837Z, 2013 WL 766192, at *3-4 (W.D. Wash. 7 Feb 28, 2013) (finding a witness with a mechanical engineering degree and years of experience 8 in the field unqualified without further information). Plaintiffs are not required to show that 9 Khan has the exact specialized expertise to answer the issues here, but Plaintiffs do have the 10 burden to show by a preponderance of the evidence that he is qualified based on his knowledge, 11 skill, experience, training, and/or education for this Court to find him an expert with a reliable or 12 appreciably helpful opinion for a jury. Furthermore, Khan stating in his deposition that his expert 13 declaration was “all drafted by” Plaintiffs’ counsel raises serious credibility and reliability 14 questions that Plaintiffs do not respond to. See Dkt. #182-1, Ex. A, at 38:11-17 (“Q. Did you 15 write this declaration? A. No. It was drafted by Mr. Andrew. Q. Did you write any partt of this 16 declaration? Or was it all drafted by Mr. Ryan? A. No. I did not draft anything, but it was my 17 opinion where – as I said earlier, incorporated in my declaration.”) and 42:12-14 (“Q. Okay. So 18 what parts of this declaration, if any, contain sentences that you yourself wrote? A. No. It’s all 19 drafted by Mr. Ryan.”); see also Fed. R. Civ. P. 26(a)(2)(B) (expert witness must provide “a 20 written report—prepared and signed by the witness”). Given all of the above, the Court finds 21 that Plaintiffs have failed to show that Khan is qualified as an expert in this case. Accordingly, 22 the Court will grant Defendants’ Motion. 23 24 1 Having considered the instant Motion, declarations and attached exhibits, responsive briefings, and the remainder of the docket, the Court hereby finds and ORDERS that Defendants’ 2 Motion to Exclude Expert Testimony of Muhammad Khan, Dkts. #177 and #183, is GRANTED. 3
