Last Friday, when lawyers from three firms – Robins, Kaplan, Miller & Ciresi, Robbins Geller Rudman & Dowd and Berger & Montague – asked to withdraw as counsel to the National Association of Convenience Stores in the proposed $7 billion antitrust class action settlement with Visa and MasterCard, they said that they only learned of NACS’s opposition to the deal right before the settlement was filed with U.S. District Judge John Gleeson in Brooklyn. That’s not what NACS’s new lawyers at Constantine Cannon said in a brief filed Tuesday night. If there was any doubt that there’s going to be a battle royal over this settlement, the new brief should remove it.
