A week after handing down a lifetime ban, the NBA’s strategy to oust Donald Sterling is starting to take shape.

According to USA Today, the league will rely on moral and ethical contracts that the Los Angeles Clippers owner signed in the past — arguing that his racist comments constituted a violation of those terms.

A source told USA Today that those contracts stipulate that the 80-year-old Sterling cannot express views or take actions detrimental to the NBA.

The NBA could then rely on Article 13(d) of its constitution, which states that owners who “fail or refuse to fulfill its) contractual obligations to the Association, its Members, Players, or any other third party in such a way as to affect the Association or its Members adversely” may be terminated by a majority three-fourths vote.
