The Court of Justice of the European Union ruled last week that an Italian law which forced Vivendi, Mediaset second-biggest shareholder, to freeze most of its voting rights in the Italian group violated EU rules.

A person close to the matter said AGCOM had begun reviewing the ruling and expected to reach a conclusion shortly.

AGCOM hopes to clarify in 10 days whether the Italian antitrust law is still in force after EU court ruling, the sources added.
