The Cour de cassation, France’s supreme civil court, ruled that a recording of a telephone conversation between the participants of an alleged cartel, made by one of the participants, did not constitute admissible evidence of an anticompetitive arrangement. The other participants of the alleged cartel had not been aware that their conversation was being taped. The French Competition Council had used the recording as evidence to fine French subsidiaries of Sony and Philips a total of e16 million for entering into a resale price arrangement with their retailers.
