88In this respect, Article 81(1) EC precludes any direct or indirect contact between economic operators of such a kind as either to influence the conduct on the market of an actual or potential competitor or to reveal to such a competitor the conduct which an operator has decided to follow itself or contemplates adopting on the market, where the object or effect of those contacts is to restrict competition (see, to that effect, Commission v Anic Partecipazioni, paragraph 87 above, paragraphs 116 and 117).
