Over the past three years, leaders of US antitrust agencies have been driving antitrust enforcement into the public consciousness.  While fewer antitrust actions were filed in 2022, of the number of private antitrust class actions growing out of criminal and civil investigations conducted by the two agencies is likely to increase over the next few years.  It may also reshape the way courts view these private antitrust class actions, and whether they are more likely to deny motions to dismiss and to more inclined to grant class certification is up for debate.  The potential damages in many of these cases run into the hundreds of millions, some a billion dollars or more.

To help you and your clients understand where we are and stay ahead of the curve, this webinar will examine recent decisions in antitrust class actions, such as the Ninth Circuit’s en banc decision last fall granting class certification in Olean Wholesalers v. Bumblebee. The speakers will identify key issues and emerging trends and will suggest strategies for addressing them.

Join a panel of experienced antitrust lawyers and economists for a lively discussion reflecting both plaintiff and defendant points of view.

Key topics include:

  • What lessons to take away from the Ninth Circuit decision in Olean Wholesalers
  • How courts are now treating the use of regression models to prove classwide impact
  • How to use Daubert motions effectively on class certification
  • Emerging issues on the scope of discovery in antitrust class actions

  • Class certification is a make or break step in most antitrust class actions.  If the class is not certified, then the case is usually dropped.  Certifying a class typically results in substantial settlement the plaintiffs.
  • Courts have found economic analyses, such as regressions, are critical for estimating damages and identifying whether substantially all class members were affected by the alleged antitrust conspiracy.
  • The recent En Banc 9th Circuit decision in Olean Wholesalers v. Bumblebee discusses in detail the economic experts’ analyses supporting and challenging class certification, and explains which analyses it considered most reliable.
  • There are clear lessons to be learned for both attorneys and economists from studying the En Banc Olean and other recent antitrust certification decisions.
