Judge Cites Dr. Lamb’s Analysis in Certifying Class of Direct Purchasers of Gypsum Wallboard
In 2013, Plaintiffs filed a Consolidated Amended Complaint on behalf of a proposed class of direct purchasers of gypsum wallboard alleging price-fixing by Defendants. Counsel for the Plaintiffs retained Dr. Russell Lamb to analyze whether the co-conspirators engaged in a conspiracy to fix, maintain, or stabilize prices of gypsum wallboard; whether prices of gypsum wallboard were artificially inflated due to the alleged cartel; whether there was widespread payment of overcharges across the proposed class; and whether aggregate damages to the proposed class as a whole could be reliably computed using standard economic methods and analyses. Dr. Lamb filed two Expert Reports concerning class certification issues, two Expert Reports concerning liability and damages issues,* and one Supplemental Expert Report responding to a report submitted by a technical advisor retained by the Court. Dr. Lamb also testified at deposition twice concerning class certification and at an extensive evidentiary hearing on the issue of class certification.
