(CNN) - Los Angeles Clippers co-owner Donald Sterling made clear he wasn't going away Friday, suing the NBA for more than $1 billion for its decision to ban him for life and force him to sell the franchise.
The lawsuit - which was provided to CNN by Sterling's lawyer and wasn't unexpected - marks the latest twist in a case that began last month when TMZ posted a recording in which Sterling made a racist comments. It also comes amid fresh questions about the 80-year-old's mental state, which itself raises the issue of how much control he has or should have with the Clipppers.
Among other allegations, Sterling's camp claims in its lawsuit that the recording that spawned this scandal - and that recording, it says, is the sole base of the NBA charges against him - is against California law and that Sterling never violated the NBA's constitution.
The lawsuit also states that "the forced sale of the Los Angeles Clippers threatens not only to produce a lower price than a non-forced sale, but more importantly, it injures competition and forces antitrust injury by making the ... market unresponsive to ... the operation of the free market."
