U.S. District Judge Michael Baylson granted CertainTeed’s motion for summary judgment in a multi-district price-fixing litigation but ordered all other remaining drywall manufacturers to remain in the case. EI Chairman Barry Harris testified at deposition on behalf of CertainTeed. Plaintiffs alleged that beginning in 2011 the defendants conspired to raise prices by 35% and stop providing customers with job quotes. The opinion agreed with CertainTeed that it had independently followed pricing moves by its competitors. Dr. Harris’ analysis considered whether CertainTeed’s pricing actions were in its independent economic interest, which included consideration of CertainTeed’s cost structure and product mix. EI economists Stephanie Mirrow and Su Sun also worked on the case. CertainTeed is represented by White & Case.
