Credit card class action

BROOKLYN — A federal court in New York said no to a motion that would have decertified an antitrust and consumer protection class action against Visa and Mastercard, which businesses have accused accused of conspiring to adopt the Europay, Mastercard & Visa chip-enabled credit card payment system in order to shift billions of dollars in liability for fraudulent chargebacks onto the merchants themselves. An expert rebuttal that presented a theory of liability regarding small- and medium-sized merchants failed to justify decertification.
