I’m very excited to be speaking at a Strafford Publications CLE webinar tomorrow entitled: Statistics in Class Action Litigation: Admissibility, Expert Witnesses and Impact of Comcast v. Behrend.   The program is scheduled for June 18, 2013 at  1:00pm-2:30pm EDT.  This is the third iteration of this presentation, which has been updated to offer insights in light of the Supreme Court’s Comcast decision earlier this term.  Brian Troyer of Thompson Hine in Cleveland and Justin Hopson and Rick Preston from Hitachi Consulting in Denver will be co-presenting.  Below is a synopsis of the program.  Click here for more information and to register:

Class certification standards have become more rigorous, and the skillful use of statistical evidence is an important part of class actions. Effectively employing or challenging statistics can make a difference in winning or losing a class certification motion.

Statistical evidence is introduced through expert witness testimony, and Daubert challenges may be an effective strategy. This raises the issue of the scope of the court’s inquiry into the merits at the class certification stage.

The 2011 Wal-Mart v. Dukes Supreme Court ruling underscored the prominent role of statistical evidence in assessing the merits at the certification stage. The Court’s recent Comcast v. Behrend ruling reinforces Dukes regarding merits assessments at class certification, thus impacting the continued role of statistical evidence.

Listen as our experienced panel examines statistical evidence in certification proceedings, the impact of Comcast v. Behrend and related case law, and best practices for using statistics and cross-examining witnesses.

Outline

  1. Role of statistical evidence in support of class certification
  2. Expert testimony and Daubert analysis at class certification stage
  3. Impact of Comcast v. Berhrend and Wal-Mart v. Dukes
  4. Science of statistics and cross-examining the statistics witness

Benefits

The panel will review these and other key questions:

  • What is the impact of Comcast and Dukes upon the use of statistical analysis at class certification?
  • What strategies can counsel use to effectively cross-examine statistics witnesses?
  • What types of statistics can be introduced and what are the proper ways to utilize statistics?

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

My partner, Bob Abrams, sent me a copy of the order granting Plaintiffs’ Renewed Motion for Class Certification in Allen v. Dairy Farmers of America, an antitrust class action brought on behalf of dairy farmers alleging monopolization and a conspiracy to fix milk prices by various milk cooperatives and processors.  Abrams’ team has been appointed as class counsel for one of the subclasses certified as part of the order. 

The opinion includes an interesting analysis of at least two important issues: First, the extent to which intra-class conflicts of interest can prevent class certification and the extent to which the creation of subclasses can remedy those conflicts; and Second, the extent to which a defendant can avoid class certification in an antitrust case by pointing out alleged flaws in the plaintiffs’ expert’s opinion that a common, class-wide antitrust injury exists or by presenting conflicting expert testimony.  The second issue is one that may be clarified when the Supreme Court rules later this term on Comcast v. Behrend.

I’m very excited to be speaking at an upcoming Strafford Publications CLE webinar entitled: Statistics in Class Action Litigation: Admissibility and the Impact of Wal-Mart v. Dukes.   The program is scheduled for Thursday, October 6, at  1:00pm-2:30pm EDT.  This is a beefed up version of a presentation that Justin Hopson and I did for the Colorado Bar Association class actions subsection earlier this year.  Brian Troyer of Thompson Hine in Cleveland will be joining us this time around.  Here’s a synopsis of the program, followed by a link to the registration page:

As class certification standards have become more rigorous, the use of statistical evidence in certification proceedings has become an integral part of class action litigation. Effectively using or challenging statistics can be the difference between winning and losing a class certification motion.

Since statistical evidence is introduced through expert witness testimony, Daubert challenges may be an effective strategy. This raises the issue of the scope of the court’s inquiry into the merits at the class certification stage.

The prominent role of statistical evidence in class certification is underscored in Wal-Mart v. Dukes. The Court weighed in on both the level of statistical proof to sustain certification as well as the appropriate standard for a Daubert analysis.

My fellow panelists and I will provide class action counsel with a review of the Court’s treatment of statistical evidence and expert testimony in Wal-Mart v. Dukes, discuss admissibility and use of statistics in certification proceedings, and outline strategies for using statistics and cross-examining statistics witnesses.

We will offer our perspectives and guidance on these and other critical questions:

  • How did the Supreme Court in Wal-Mart v. Dukes address the level of Daubert analysis at the class certification stage?
  • What types of statistics can be introduced and what are the proper ways to utilize statistics?
  • What strategies can counsel use to effectively cross-examine statistics witnesses?
  • What are the recent trends in the use of statistical evidence to support a class certification motion?

After our presentations, we will engage in a live question and answer session with participants — so we can answer your questions about these important issues directly.

I hope you’ll join us.

I’m embarrassingly late in reporting on them, but I would be remiss if I did not mention two key recent United States Circuit Courts of Appeals decisions addressing the legal standards governing class certification under FRCP 23:

In American Honda Motor Co. v. Allen, No. 09-8051 (7th Cir., April 7, 2010) the Seventh Circuit held that a district court abused its discretion by failing to conduct a Daubert inquiry into the admissibility of expert testimony before relying on that testimony in determining that the plaintiff had met his burden of establishing the elements of class certification. 

Meanwhile, in Dukes v. Wal-Mart Stores, Nos. 04-16688 and 04-16720 (9th Cir., April 26, 2010) (en banc), the Ninth Circuit Court of Appeals clarified that circuit’s standards for conducting the “rigorous analysis” necessary to determine whether the elements of Rule 23 are satisfied.  Following extensive discussion of the history of class certification standards both outside and within the Ninth Circuit, the court articulated class certification standards that essentially mirror those recognized in the Second Circuit’s decision in In re IPO Securities Litigation, 471 F.3d 24 (2d Cir. 2006).  However, applying those standards, the court came to a very different result, affirming certification of a nationwide class of thousands of female employees seeking injunctive and declaratory relief, back pay, and punitive damages arising out of allegedly common, discriminatory employment practices.

Both decisions are worthy of careful reading and study, and you will no doubt hear more about both decisions in the weeks and months ahead.
