This CLE webinar will analyze developments in class certification in the year since the Supreme Court issued its landmark ruling in Wal-Mart v. Dukes. The panel will examine courts' various treatment of evidence and issue commonality and outline best practices for attorneys in the current environment.


When the Supreme Court issued its watershed decision in Wal-Mart v. Dukes, it provided defendants with a tool in their efforts for defeating class certification. However, lower courts' applications of the ruling have been far from uniform.

Following the decision, uncertainty remains. One key question is how much evidence plaintiffs need to present at the class certification stage. Another is how to determine whether questions of law or fact are commonly shared by class members.

Since the decision, plaintiffs and defendants alike have encountered a variety of approaches by courts to their analyses for both questions. The Supreme Court has signaled it will revisit evidentiary issues during the 2012-13 term with the Comcast and Amgen cases.

Listen as our panel examines how courts have addressed issues of evidence and issue certification since the landmark Wal-Mart v. Dukes ruling, reviews new evidentiary issues in class certification before the Supreme Court, and offers best practices in the current environment for obtaining or defeating class certification.

The panel will review these and other key questions:

  • Are courts requiring the degree of evidence necessary at the class certification stage be the same as what is necessary at the merits stage?
  • Given the Supreme Court's ruling on commonality, how have lower courts certified issues and avoided denying certification entirely?
  • What evidentiary issues are before the Supreme Court in the Comcast and Amgen cases?

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