LOS ANGELES » The NBA canceled a hearing to oust Los Angeles Clippers co-owner Donald Sterling, instead moving forward to vote on a record-breaking deal negotiated by his wife to sell the team to former Microsoft CEO Steve Ballmer for $2 billion.

The league announced the move Friday, the same day Sterling’s attorneys filed suit in a Los Angeles federal court against the NBA and Commissioner Adam Silver asking for damages in excess of $1 billion.

Sterling opposes the sale, but Shelly Sterling was able to negotiate with Ballmer because her estranged husband was stripped of his ability to act as a co-trustee of the family’s assets after two neurologists determined he was suffering from dementia, according to a person close to the Sterling family.

The individual, who is familiar with the trust and the medical evaluations but wasn’t authorized to speak publicly, said Sterling was deemed “mentally incapacitated” according to the trust’s conditions because he showed “an inability to conduct business affairs in a reasonable and normal manner.”

“There is specific language and there are protocols about what to do, and steps in order to get a sole trustee position and that’s what took place in the last couple of days,” the individual said.

But the lawsuit identifies Donald Sterling as a co-trustee and his lawyer, Bobby Samini, said “the assertion that Donald Sterling lacks mental capacity is absurd.” He would not give more details on Donald Sterling’s condition.

The suit alleges that the NBA violated Sterling’s constitutional rights by relying on information from an “illegal” recording that publicized racist remarks he made to a girlfriend. It also says the league committed a breach of contract by fining Sterling $2.5 million and that it violated antitrust laws by forcing a sale.

Shelly Sterling said that she had agreed to sell the team to Ballmer “under her authority as the sole trustee of The Sterling Family Trust, which owns the Clippers.”

Sterling can try to reinstate his trusteeship by appealing to the California Probate Court.

The NBA said Friday that the league, Shelly Sterling and The Sterling Family Trust had “resolved their dispute over the ownership of the Los Angeles Clippers.”

“Under the agreement, the Clippers will be sold to Steve Ballmer, pending approval by the NBA Board of Governors, and the NBA will withdraw its pending charge to terminate the Sterlings’ ownership of the team,” it said.

The league said that Shelly Sterling and The Sterling Family Trust also “agreed not to sue the NBA and to indemnify the NBA against lawsuits from others, including Donald Sterling.”

That means whatever monetary damages Donald Sterling may receive under the suit — filed by his attorney Maxwell Blecher on behalf of Sterling and The Sterling Family Trust — may go out one pocket and back in the other unless he is reinstated as a trustee and can nullify the agreement.

The medical evaluation was made earlier this month when Donald Sterling made voluntary visits to two neurologists who conducted tests, including brain scans, the individual said. Though Donald Sterling is no longer a co-trustee of The Sterling Family Trust, he still retains his 50 percent ownership and still receives proceeds from the sale, the individual said.

Despite a deal that would make him even more wealthy, Sterling — who paid just $12 million for the Clippers in 1981 — is still fighting. His lawsuit seeks the elimination of his lifetime ban from the NBA, and the reinstatement of former Clippers CEO Andy Roeser.

“Mr. Sterling’s lawsuit is predictable, but entirely baseless,” NBA general counsel Rick Buchanan said. “Among other infirmities, there was no ‘forced sale’ of his team by the NBA — which means his antitrust and conversion claims are completely invalid. Since it was his wife Shelly Sterling, and not the NBA, that has entered into an agreement to sell the Clippers, Mr. Sterling is complaining about a set of facts that doesn’t even exist.”

The ownership hearing had been scheduled for next Tuesday after the NBA charged Sterling with damaging the league with his racist comments. A three-quarters vote of owners to support the charge would have terminated the Sterlings’ ownership, and the league would have sold the team.

Ballmer said in a statement that he is honored to have his name submitted to the NBA for approval. The price has blown past previous offers for an NBA team.

“Obviously, I saw $2 billion. That gave me a reaction,” said Miami Heat star LeBron James, who had been vocal in calling for both Sterlings to be out of the league. “That was a reaction for sure. But as far as everything else, I haven’t quite dived into it. … Any time a ‘B’ goes after a number, man, you already know that you’re talking about some real money.”

This is not Ballmer’s first foray into potential NBA ownership. Ballmer and investor Chris Hansen headed a group that agreed to a deal to buy the Kings from the Maloof family in January 2013 with the intention of moving the team to Seattle, where the SuperSonics played until 2008.

But Sacramento Mayor Kevin Johnson lobbied the NBA for time to put together a bid to keep the team in California, and though the Ballmer-Hansen group later increased its offer, owners voted to deny the bid for relocation and the Kings were sold to Vivek Ranadive.

Johnson, who has been advising the NBA Players Association in the wake of Sterling’s comments, praised Ballmer in a series of tweets Friday night.

“When the Clips play next season, players will be proud to wear the logo on their chest & fans will be proud to cheer for their hometown team,” Johnson wrote.
