The Italian Competition Authority (the plaintiff),following several complaints, opened infringement proceedings against the defendants. The investigation concerned the defendants' advertising methods.
The defendants, which offer gaming services online, were alleged to contact the consumers through banners and promotional links on their smart phones. By simply clicking on the banners or the links of the defendants, the consumers purchased the gaming services, which were an open ended service for money that was automatically charged on the phone bills of the consumers. Many consumers complained that they were deceived in the purchase of the services: they only realized to have purchased the services when they saw that a weekly fee was charged on their phone bill.
The defendants challenged the competence of the plaintiff.
