A federal judge has dismissed conspiracy claims against Holcim (US) Inc. and Ash Grove Cement Co., two of the nation’s largest cement manufacturers. The suit alleged that the companies violated the Sherman Antitrust Act and the Robinson-Patman Act by charging lower prices for the same ready-mix cement products to preferred buyers than they charged to other purchasers. Judge Robert J. Shelby of the US District Court for the District of Utah upheld the companies’ argument that the case did not meet the US Supreme Court's Twombly pleading standards. Partner Andrew Klevorn, who represented Holcim together with associate Katherine Paulson, commented, “We are pleased by the court’s order and appreciate its careful evaluation of the issues in a thoughtful, considered manner.” (“Cement Makers Dodge Price-Fixing Conspiracy Suit,” March 31, 2014)
