In a statement, the French media concern said the decision was both unlawful and against the interests both of Mediaset and its minority shareholders.
Vivendi said it wasn’t in a position to participate at the Mediaset Shareholders’ Meeting and reserved the right to challenge in court the validity of any resolutions adopted.
It’s the latest twist in the three year old battle between Mediaset and Vivendi that emerged after Vivendi pulled out of a deal to purchase Mediasat’s pay-TV division.
Separately, Fininvest chair Marina Berlusconi has said Mediaset would like to develop a cross-border alliance, but has no intention of including Vivendi in any such deal.
Fininvest owns 44 per cent of Mediaset.
