Donald Sterling will sue the NBA for $1 billion after he was forced to relinquish ownership of the Los Angeles Clippers, according to a report from NBC News.

Sterling's wife, Shelly Sterling, sold the Clippers for $2 billion to Steve Ballmer.

Sterling has recently been ruled mentally incapacitated, according to ESPN's Ramona Shelburne.

Max Blecher, attorney for Sterling, has confirmed his client's intent to file to both Adrian Wojnarowski and Shelburne.

The Los Angeles Times acquired a copy of the lawsuit, which focuses on the NBA's "draconian" punishments. Adam Silver is also a defendant in the suit.

Sterling's suit includes claims for denial of constitutional rights, breach of contract and more.
