On June 30, Mike Ruttinger was a panelist at a Barbri class action webinar, “Predominance Analysis: Multistate Classes and Choice of Law When Advocating or Opposing Certification.” The course addressed establishing or challenging Rule 23’s predominance requirement in a proposed national or multistate class action invoking laws of multiple states involving claims such as consumer protection, fraud, products liability, mass tort, or warranty claims. Mike and his co-panelists explored the viability of  class certification for multistate class actions, choice of law issues, and the meaning of Rule 23’s predominance requirement in cases involving materially different state-law claims.
