  • The Court Upholds the €61.44 Million Fine Imposed on Toshiba (Of
    Court of Justice of the European Union PRESS RELEASE No 74/17 Luxembourg, 6 July 2017 Judgment in Case C-180/16 P Press and Information Toshiba v Commission The Court upholds the €61.44 million fine imposed on Toshiba (of which €4.65 million jointly and severally with Mitsubishi) for its participation in the gas insulated switchgear cartel The fine thus becomes final By decision of 24 January 2007,1 the Commission imposed fines totalling €750.71 million on 20 European and Japanese companies2 for their participation in a cartel on the market for gas insulated switchgear (GIS) between 1988 and 2004. The undertakings which participated in the cartel concluded an agreement with a view to coordinating their commercial activity worldwide and developed a quota system aimed at determining the market shares which each group could share among its members. According to the Commission, the cartel participants also concluded an unwritten understanding to reserve the European market to European undertakings and the Japanese market to Japanese undertakings. Toshiba and Mitsubishi Electric were fined €86.25 million and €113.92 million respectively. In addition to those two fines, the two Japanese companies were ordered to pay a further amount of €4.65 million joint and severally. That amount corresponds to the infringement committed by TM T&D Corp., a company jointly owned in equal shares by Toshiba and Mitsubishi, through which Toshiba had carried on its GIS business between October 2002 and April 2005. By judgments of 12 July 2011,3 the General Court of the European Union annulled the fines imposed on Toshiba and Mitsubishi, finding that the Commission had infringed the principle of equal treatment in calculating those fines.
