Varios comerciantes minoristas (MP) van a juicio contra American Express (Amex) alegando que el uso de Amex de una regla ‘antirretorno’ en sus contratos viola la ley antimonopolio de EEUU, luego de que tres de los cuatro mercados relevantes descritos en sus demandas fueran rechazados por el juez de distrito. El lunes 14 de enero, el juez de distrito de los Estados Unidos, Nicholas Garaufis, del Distrito Este de Nueva York, aprobó la moción de Amex para llevar a cabo un juicio sumario parcial.
