Montera v. Premier Nutrition Corporation

Background

Mary Beth Montera brought a class action alleging that Premier Nutrition Corporation falsely advertised Joint Juice, a joint-health dietary supplement, in violation of New York General Business Law §§ 349 and 350. The court had previously certified a class of New York consumers. Premier moved to exclude four experts and to decertify the class. Montera moved to exclude seven experts.

The court evaluated the expert testimony under Federal Rule of Evidence 702 and the reliability and relevance principles associated with Daubert. The court explained that weaknesses affecting the weight of testimony—meaning how persuasive it is—ordinarily should be addressed through cross-examination rather than exclusion.

Premier’s Motions to Exclude

- Dr. Farshid Guilak: Granted as to opinions based on experiments using dissolved pills from other glucosamine and chondroitin supplements on pig cartilage. Montera did not show that Guilak’s process for dissolving off-the-shelf pills was reliable or accepted in the scientific community. The opinion states that Premier had not challenged Guilak’s opinions about joint physiology or the opinions in his rebuttal report. - Dr. J. Michael Dennis: Denied. The court held that concerns about his survey’s closed-ended questions, lack of a control group, and selection of respondents at least 35 years old went to the weight of the evidence and could be explored through cross-examination. - Dr. Derek Rucker: Granted in part and denied in part. Rucker may testify about general marketing principles, Premier’s marketing strategies, and Premier’s intended message and target audience. He may not testify about how consumers actually interpreted the intended marketing message because his support for that opinion largely consisted of the Dennis survey. - Dr. Colin Weir: Denied. The court held that New York General Business Law §§ 349(h) and 350-e allow statutory damages on a per-unit basis, so Weir may testify about calculations using that approach.

Montera’s Motions to Exclude

- Dr. Stuart L. Silverman: Granted in part and denied in part. Silverman may testify about scientific support for glucosamine and chondroitin health benefits and the studies underlying those opinions. He may not testify about the gut microbiome, bioavailability, the effectiveness of glucosamine based on personal clinical observations, regulatory approvals abroad, or the importance of developing alternative osteoarthritis treatments. - Dr. Daniel A. Grande: Granted in part and denied in part. Grande may testify about the biomarker, animal, and in vitro studies he relied on, although Montera may cross-examine him about their weaknesses. He may not testify about the gut microbiome or bioavailability. Any opinions previously excluded by the court also remain excluded if offered at trial. - Dr. William S. Choi: Denied. The court treated Choi’s report as a proper rebuttal report addressing Weir’s damages opinions. His testimony about actual damages was relevant even though statutory damages might exceed actual damages, because the statute permits recovery of the greater amount. - Hal Poret: Denied. Although the court found Poret’s survey had limited value, it concluded that the survey was relevant and that methodological concerns could be addressed through cross-examination. - Dr. Joel Steckel: Denied. Steckel’s opinions criticizing the Dennis survey were relevant and supported by citations. The lack of his own survey or data affected cross-examination rather than admissibility. - Dr. Kevin Robert Stone: Granted. Premier’s disclosure did not adequately summarize Stone’s expected opinions and supporting facts. The court also ruled that opinions based on studies Stone reviewed in preparation for litigation required a written expert report, which Premier had not provided. - Lance Palumbo: Granted. Premier’s disclosure did not adequately identify Palumbo’s expected opinions and supporting facts. The court also concluded that Palumbo lacked the scientific expertise to testify about scientific studies or the benefits of Joint Juice.

Motion to Decertify the Class

The motion to decertify was denied. The court held that common evidence could establish causation under New York’s consumer-protection laws, including evidence about Premier’s coordinated advertising campaign, consumers’ reasons for buying Joint Juice, and Dennis’s survey. The same common evidence could address the causal connection required for Article III standing, so individual standing inquiries would not predominate.

The court also held that Montera may pursue a full-refund damages theory if she proves that Joint Juice was valueless for its advertised purpose. Whether the product was valueless is a question for the jury, and Montera bears the burden of proving it at trial. The court further held that common issues predominate as to damages because statutory damages are available on a per-unit basis.

Other Orders and Disposition

The court denied the administrative motions to file materials under seal and directed Montera to file unredacted versions of the redacted materials on the public docket within five days. The scheduled hearing was vacated because the matter was suitable for decision without oral argument.

Judge Richard Seeborg ordered that Premier’s motion to exclude Guilak’s challenged opinions was granted; Premier’s motion concerning Rucker was granted in part and denied in part; Premier’s other expert motions were denied; Montera’s motions concerning Stone and Palumbo were granted; Montera’s motions concerning Silverman and Grande were granted in part and denied in part; Montera’s motions concerning Steckel, Choi, and Poret were denied; and Premier’s motion to decertify the class was denied. The order did not decide the ultimate merits of the false-advertising claims.
