Course Materials

This CLE course will discuss best practices for using experts at various stages of product liability class action litigation, including class certification, manifestation of product defect, causal factors in consumer behavior, and economic damages.


Product liability class action suits invariably focus on consumer fraud and unfair trade practice claims. The damages sought in such cases are economic, and expert witnesses are critical at various stages of the litigation for a variety of issues.

Experts play an important role in the battle over class certification (consolidated in MDLs or otherwise) and to address issues concerning how the alleged defect in the product manifested.

Experts are also critical to establishing causal factors that tend to implicate consumer decision making, as well as complex diminution, depreciation and hedonic economic damages questions.

Listen as our authoritative panel of product litigators discusses best practices for using expert witnesses at various stages of a product liability class action, from class certification to causation to economic damages.



  1. Expert’s role in class certification
  2. Expert’s role in manifestation of product defect
  3. Expert’s role in causal factors in consumer behavior
  4. Expert’s role in economic damages issues


The panel will review these and other key questions:

  • What are the different standards of evaluating expert testimony that courts are employing at class certification?
  • How are experts used to show causal factors in consumer behavior and manifestation of product defect?
  • How can counsel best leverage expert witnesses to prove or attack damages?

Following the speaker presentations, you'll have an opportunity to get answers to your specific questions during the interactive Q&A.
