Summary
The United States District Court for the Northern District of California denied without prejudice Michaels Stores, Inc.’s motions to exclude opinions by plaintiffs’ experts Bruce G. Silverman and Colin B. Weir. The court held that challenges to the experts’ qualifications, methodologies, and conjoint analysis primarily concerned the weight of their opinions rather than admissibility at the class-certification stage.

Questions Presented
- Whether portions of Silverman's opinions concerning consumer deception, the importance of Michaels' coupon discounts, and the effect of Michaels' advertising should be excluded under Rule 702 and Daubert.
- Whether Silverman's opinions should be excluded as beyond his expertise, unsupported by reliable principles or methods, or improperly invading the province of the jury.
- Whether portions of Weir's opinions relying on conjoint analysis should be excluded as novel, unreliable, or insufficiently attentive to relevant inputs and supply-side factors.
- Whether, at the class-certification stage, the defendants' criticisms of the experts' methodologies went to admissibility or merely to the weight of the opinions.
Holdings
- When expert testimony is offered in support of class certification, the district court must evaluate its admissibility under Daubert through a tailored analysis that considers reliability in light of the class-certification criteria and the current record.
- Silverman's opinions concerning whether Michaels' alleged discount practices would mislead reasonable consumers were not excludable merely because they addressed an ultimate issue; the opinions addressed consumer-related factual matters rather than legal conclusions.
- At this stage, Silverman's opinions were not excludable based on challenges to the scope of his expertise, his reliance on hypothetical facts, his methodology, or the contention that the jury could analyze the facts without expert assistance.
- The defendant's challenges to Weir's conjoint-analysis opinions did not warrant exclusion at this stage because the objections concerned the methodology, survey design, reliability, inputs, and conclusions, which went to the weight rather than the admissibility of the opinions.
