The Fair Trade Commission (“FTC”) found four convenient stores to have committed concerted action in increasing the price of freshly brewed coffee in 2011.  The Taipei High Administrative Court, upon the stores’ appeal against FTC’s decision, revoked FTC’s decision on the ground that FTC failed to prove the existence of concerted action among the four stores.  Upon FTC’s appeal, the Supreme Administrative Court vacated the Taipei High Administrative Court’s judgment, ruling that FTC’s finding of concerted action can be sustained based on reasonable assumption if it is difficult for the competent authority to obtain direct evidence of the common understanding or collaboration under a concerted action, provided, however, that the parties may overcome the assumption of concerted action by proving that the price adjustment is due to objective change in the market demand and supply.
