12 Plaintiff, ORDER DENYING MOTIONS TO 13 v. EXCLUDE EXPERT OPINIONS
14 RUST-OLEUM CORPORATION, Re: ECF Nos. 131, 163 15 Defendant. 16 17 INTRODUCTION AND STATEMENT 18 This is a consumer-products mislabeling case. On behalf of a class of California consumers, 19 the plaintiff challenges defendant Rust-Oleum’s labeling of its “Krud Kutter” cleaning products as 20 “non-toxic” and “Earth friendly,” contending that the products in fact can cause harm to humans, 21 animals, and the environment, in violation of California consumer-protection laws. The parties 22 moved to exclude each other’s survey experts.1 The court denies the motions. 23 The operative complaint has five claims: (1) unlawful, unfair, and fraudulent business 24 practices under the Unfair Competition Law (UCL), Cal. Bus. & Prof. Code §§ 17200–08; (2) 25 deceptive advertising under the False Advertising Law (FAL), Cal. Bus. & Prof. Code § 17500; 26 27 1 1 (3) deceptive practices under the Consumer Legal Remedies Act (CLRA), Cal. Civ. Code §§ 2 1750–84; (4) breach of express warranties; and (5) unjust enrichment.2 3 It is undisputed that the court has diversity jurisdiction under the Class Action Fairness Act. 28 4 U.S.C. § 1332(d). All parties consented to magistrate-judge jurisdiction.3 Id. § 636(c). The court 5 held a hearing on January 25, 2024. 6 ANALYSIS 7 1. Legal Standard 8 “A witness who is qualified as an expert by knowledge, skill, experience, training, or education 9 may testify in the form of an opinion or otherwise” if four requirements are met: “(a) the expert’s 10 scientific, technical, or other specialized knowledge will help the trier of fact to understand the 11 evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the 12 testimony is the product of reliable principles and methods; and (d) the expert’s opinion reflects a 13 reliable application of the principles and methods to the facts of the case.” Fed. R. Evid. 702; see 14 Daubert v. Merrill Dow Pharms., Inc., 509 U.S. 579 (1993). “Under Daubert, the trial court must 15 act as a ‘gatekeeper’ to exclude junk science that does not meet Federal Rule of Evidence 702’s 16 reliability standards by making a preliminary determination that the expert’s testimony is reliable.” 17 Ellis v. Costco Wholesale Corp., 657 F.3d 970, 982 (9th Cir. 2011) (citing Kumho Tire Co. v. 18 Carmichael, 526 U.S. 137, 145, 147–49 (1999)). “Daubert does not require a court to admit or to 19 exclude evidence based on its persuasiveness; rather it requires a court to admit or exclude evidence 20 based on its scientific reliability and relevance.” Id. (citing Daubert, 509 U.S. at 589–90). “Thus, an 21 expert’s ‘inference or assertion must be derived by the scientific method’ to be admissible.” Id. 22 (quoting Daubert, 509 U.S. at 590). “A trial court has broad latitude not only in determining 23 whether an expert’s testimony is reliable, but also in deciding how to determine the testimony’s 24 reliability.” Id. (citing Kumho Tire, 526 U.S. at 152). 25 The court “must assure that the expert testimony ‘both rests on a reliable foundation and is 26
27 2 First Am. Compl. – ECF No. 26 at 31–43 (¶¶ 66–161). 1 relevant to the task at hand.’” Primiano v. Cook, 598 F.3d 558, 564 (9th Cir. 2010) (quoting 2 Daubert, 509 U.S. at 597). “Expert opinion testimony is relevant if the knowledge underlying it has 3 a valid connection to the pertinent inquiry. And it is reliable if the knowledge underlying it has a 4 reliable basis in the knowledge and experience of the relevant discipline.” Id. at 565. “Shaky but 5 admissible evidence is to be attacked by cross examination, contrary evidence, and attention to the 6 burden of proof, not exclusion.” Id. at 564. The test “is not the correctness of the expert’s 7 conclusions but the soundness of his methodology,” and when an expert meets the requirements of 8 Rule 702, the expert may testify and the fact finder decides how much weight to give that 9 testimony. Id. at 564–65. 10 At issue here are expert surveys. The Ninth Circuit has said that at least in trademark cases, 11 “[c]hallenges to survey methodology go to the weight given the survey, not its admissibility.” 12 Wendt v. Host Int’l, Inc., 125 F.3d 806, 814 (9th Cir. 1997). Put another way, “[t]echnical 13 unreliability goes to the weight accorded a survey.” Prudential Ins. Co. of Am. v. Gibraltar Fin. 14 Corp. of Cal., 694 F.2d 1150, 1156 (9th Cir. 1982). Arguments that a survey’s sample was 15 unrepresentative, for example, go to weight only. Southland Sod Farms v. Stover Seed Co., 108 16 F.3d 1134, 1143 (9th Cir. 1997). “Surveys conducted according to accepted principles are 17 routinely admitted.” Prudential, 694 F.2d at 1156; ThermoLife Int’l, LLC v. Gaspari Nutrition 18 Inc., 648 F. App’x 609, 613 (9th Cir. 2016) (applying this standard in the false-advertising 19 context). 20 21 2. Application 22 2.1 The Plaintiff’s Motion 23 The plaintiff moves to exclude the opinions and survey of the defendant’s market-research 24 expert Dr. Ran Kivetz. Dr. Kivetz asked questions of a test group and a control group: the test 25 group was shown the actual label of one of the Krud Kutter products, and the control group was 26 shown the same label but without the challenged label claims (“non-toxic” and “Earth friendly”). 27 The respondents were then asked questions including whether they would buy the product shown 1 and (in open-ended form) why they would or would not buy it.4 The court first summarizes the 2 plaintiff’s arguments and then denies the motion. 3 First, the plaintiff contends that some of Dr. Kivetz’s opinions are irrelevant. Dr. Kivetz 4 opined, based on the difference between the test and control groups in whether they would 5 purchase the product, that the challenged claims are not a but-for cause of purchasing decisions. 6 He also opined based on the open-ended responses that there are a variety of reasons for 7 consumers’ purchasing decisions. The plaintiff argues that under the reasonable-consumer test, the 8 challenged claims can be “material” to purchasing decisions even if the claims are not a but-for 9 cause of the decisions and a variety of factors go into the decisions. 10 Second, the plaintiff contends that Dr. Kivetz’s survey is unreliable because he used an 11 improper control. According to the plaintiff, the control had the same features as the test because 12 the control had “references to ‘non-toxic’ and ‘Earth friendly’ features” in the form of “the 13 ‘biodegradability’ claim and the Environmental Protection Agency’s ‘Safer Choice’ seal on the 14 front packaging; as well as the word ‘safely’ from the back-packaging claim that the formula 15 ‘safely and easily’ removes various substances.” 16 Third, the plaintiff argues that Dr.

Application 22 2.1 The Plaintiff’s Motion 23 The plaintiff moves to exclude the opinions and survey of the defendant’s market-research 24 expert Dr. Ran Kivetz. Dr. Kivetz asked questions of a test group and a control group: the test 25 group was shown the actual label of one of the Krud Kutter products, and the control group was 26 shown the same label but without the challenged label claims (“non-toxic” and “Earth friendly”). 27 The respondents were then asked questions including whether they would buy the product shown 1 and (in open-ended form) why they would or would not buy it.4 The court first summarizes the 2 plaintiff’s arguments and then denies the motion. 3 First, the plaintiff contends that some of Dr. Kivetz’s opinions are irrelevant. Dr. Kivetz 4 opined, based on the difference between the test and control groups in whether they would 5 purchase the product, that the challenged claims are not a but-for cause of purchasing decisions. 6 He also opined based on the open-ended responses that there are a variety of reasons for 7 consumers’ purchasing decisions. The plaintiff argues that under the reasonable-consumer test, the 8 challenged claims can be “material” to purchasing decisions even if the claims are not a but-for 9 cause of the decisions and a variety of factors go into the decisions. 10 Second, the plaintiff contends that Dr. Kivetz’s survey is unreliable because he used an 11 improper control. According to the plaintiff, the control had the same features as the test because 12 the control had “references to ‘non-toxic’ and ‘Earth friendly’ features” in the form of “the 13 ‘biodegradability’ claim and the Environmental Protection Agency’s ‘Safer Choice’ seal on the 14 front packaging; as well as the word ‘safely’ from the back-packaging claim that the formula 15 ‘safely and easily’ removes various substances.” 16 Third, the plaintiff argues that Dr. Kivetz’s survey is unreliable because it “introduce[d] pre- 17 existing attitudes” by “prominently displaying the Krud Kutter brand” in the survey and because it 18 did not use “manipulation checks to determine whether the experimental treatment — removal of 19 the ‘non-toxic’ and ‘Earth friendly’ claims in the control stimulus — was effective.” 20 Fourth, according to the plaintiff, Dr. Kivetz’s open-ended questions and the resulting analysis 21 are unreliable, mainly because close-ended questions are better suited for qualitative research and 22 open-ended questions tend to measure only what comes first to a respondent’s mind. 23 Fifth, the plaintiff contends that Dr. Kivetz’s survey is unreliable because it doesn’t properly 24 represent the class or replicate the marketplace. 25 Sixth, the plaintiff asserts that Dr. Kivetz did not provide the plaintiff all of the data used to 26 form his opinions. This data mainly concerns Dr. Kivetz’s open-ended questions, for example 27 1 “[t]he [c]oding [f]rame Dr. Kivetz developed for two purportedly blind coders to code the 2 responses to the open-ended [q]uestions.” 3 The plaintiff’s arguments mainly go to the weight that should be accorded to Dr. Kivetz’s 4 survey and opinions. The plaintiff’s attack on Dr. Kivetz’s control, for example, is about survey 5 methodology and Dr. Kivetz’s methods are generally within the bounds of accepted principles. 6 Prudential, 694 F.2d at 1156. “[A]dmit[ting] the survey and discount[ing] its probative value,” if 7 warranted, “seems the better course.” Id.; Oracle Am., Inc. v. Google Inc., No. C 10-03561 WHA, 8 2016 WL 1743116, at *6–7 (N.D. Cal. May 2, 2016) (rejecting various attacks on an expert 9 survey, including on whether the sample was representative). 10 As for the data that Dr. Kivetz did not provide, parties must disclose expert testimony “at the 11 times and in the sequence that the court orders.” Fed. R. Civ. P. 26(a)(2)(D). An expert disclosure 12 must be accompanied by a written report that includes: “(i) a complete statement of all opinions 13 the witness will express and the basis and reasons for them; (ii) the facts or data considered by the 14 witness in forming them; [and] (iii) any exhibits that will be used to summarize or support them.” 15 Fed. R. Civ. P. 26(a)(2)(B). A party should supplement its expert disclosure in a timely manner if 16 its learns the disclosure is materially incomplete or incorrect and the corrective information has 17 not otherwise been made known to the other parties. Fed. R. Civ. P. 26(e). This rule does not 18 allow parties to supplement their reports with information that was available prior to the disclosure 19 deadline. See Salgado ex rel. Salgado v. General Motors Corp., 150 F.3d 735 (7th Cir. 1998). 20 “When an act may or must be done within a specified time, the court may, for good cause, 21 extend the time: (A) with or without motion or notice if the court acts, or if a request is made, 22 before the original time or its extension expires; or (B) on motion made after the time has expired 23 if the party failed to act because of excusable neglect.” Fed. R. Civ. P. 6(b)(1). 24 If a party fails to comply with the disclosure rules, “the party is not allowed to use that 25 information or witness to supply evidence on a motion, at a hearing, or at a trial, unless the failure 26 was substantially justified or is harmless.” Fed. R. Civ. P. 37(c)(1); see also Torres v. City of Los 27 Angeles, 548 F.3d 1197, 1212 (9th Cir. 2008) (“We have explained that Rule 37(c)(1) gives teeth 1 Rule 26(a) that is not properly disclosed.”). Here, it is the defendant’s burden to show that the 2 failure to comply with Rule 26(a) is substantially justified or harmless. Torres, 548 F.3d at 1213 3 (burden is on the party facing the sanction to demonstrate that the failure to comply with Rule 4 26(a) is substantially justified or harmless; the other party is not required to articulate how he 5 would be prejudiced). 6 The reply brief narrows the data in dispute somewhat.5 Dr. Kivetz apparently used a coding 7 company to have blind coders categorize the responses to his open-ended questions. Certain 8 responses were excluded by the coding company, for example those that were “gibberish” or on 9 which the respondent spent too little time. Some of the data at issue, such as “all starts and 10 metadata reflecting the excluded interviews and basis for their exclusion” were never actually 11 provided to Dr. Kivetz. The Ninth Circuit has said that the data an expert “considered” under Rule 12 26(a) refers to data the expert “was provided or otherwise exposed to in the course of developing 13 his or her opinions.” Republic of Ecuador v. Mackay, 742 F.3d 860, 869–70 (9th Cir. 2014). The 14 plaintiff cites no cases indicating otherwise in the context of an expert’s contractor or employee. 15 As for the “pricing data that Dr. Kivetz collected to select the $9.47 price point in his survey,” 16 the defendant contends that it’s public. This indicates any failure to produce was harmless. The 17 court thus denies the plaintiff’s motion, but this portion of the motion (regarding the alleged 18 failure to produce data) is denied without prejudice to its being refiled as a separately noticed 19 motion if warranted. N.D. Cal. Civ. L.R. 7-8. 20 2.2 The Defendant’s Motion 21 The defendant moves to exclude the declaration of the plaintiff’s survey expert, Dr. J. Michael 22 Dennis. The defendant contends that Dr. Dennis committed “the same methodological errors made 23 in previously excluded surveys” in other cases. Dr. Dennis sought to determine “the extent to 24 which the reasonable consumer perceives the [c]hallenged [c]laims to mean that the [p]roducts [at 25 issue] are not harmful to humans, animals, and/or the environment.” His survey showed a 26 27 ] hypothetical label without the Krud Kutter brand name and asked respondents whether they 2 || believe that the challenged claims communicate the aforementioned meaning.° 3 Having explained why the plaintiff's arguments go to weight rather than admissibility, the 4 || court will not walk through the defendant’s motion in detail, other than to note that the same holds 5 || true. These are alleged methodological errors that, even granting the defendant’s premises, are not 6 || so severe as in the cited cases. In Senne v. Kansas City Royals Baseball Corp., for example, the 7 || survey relied “on the ability of the minor league [baseball] players to remember the type of 8 || mundane events necessary to come up with reliable answers to questions about the amount of time 9 || they spent on various types of activities.” 315 F.R.D. 523, 590 (N.D. Cal. 2016). In other key 10 cases, the court criticized rather than excluded Dr. Dennis’s report. At least in the Ninth Circuit, 11 the issues in dispute are not enough to defeat Dr. Dennis’s declaration here. The court thus denies 12 || the motion. 13 CONCLUSION 14 The court denies the motions to exclude expert opinions. This resolves ECF Nos. 131 and 163. 3 15 IT ISSO ORDERED. a 16 Dated: February 8, 2024 LAE LAUREL BEELER 18 United States Magistrate Judge 19 20 21 22 23 24 25 26 27 28 ® Def.’s Mot. — ECF No. 163.
