Vivendi has asked a Dutch court for an injunction to prevent Mediaset’s creation of MediaForEurope.
The Amsterdam court’s decision is scheduled for 10th February.
The development follows Vivendi’s accusation that Mediaset carried out an “unlawful refusal” to allow a key shareholder to vote in a crucial EGM on Friday.
Vivendi argued the Mediaset board has placed the company in “a situation of serious legal uncertainty” after ignoring an opinion on the case from the EU Court of Justice’s advocate general.
Mediaset said the EGM votes cleared the way for the creation of the new pan-European group “with a leadership position in its reference markets.”
Mediaset chairman Fedele Confalonieri also accused Vivendi of a conflict of interest and of aiming to prevent a competitor from growing its business.
