Between 1989 and 1991, there has been a financial conflict between Silvio Berlusconi and Carlo De Benedetti, two of the largest employers of those years.
On 20 June 1990 was the first verdict: the agreement between De Benedetti and Formenton was considered still valid; as a consequence, the Mondadori shares became owned by the CIR (De Benedetti) and Berlusconi left the presidency of the company.
