Donald Sterling's lawyer has written the NBA stating the owner of the Los Angeles Clippers does not intend to pay the $2.5 million fine imposed by the league for racist comments, a person with knowledge of the letter's contents said.

Sports Illustrated first reported the letter from Maxwell Blecher. The contents were confirmed by the person who spoke on the condition of anonymity.

Blecher, a prominent antitrust attorney, acknowledged sending a letter but would not discuss its contents on Friday.

NBA commissioner Adam Silver banned Sterling for life and imposed the fine following the release late last month of a recording in which Sterling makes racist remarks. Silver also called on owners to oust Sterling from the league, which would require a three-fourths vote among the league's 29 other controlling owners.

"We regard the dispute between Sterling and the NBA to be a private matter," Blecher said. "We do not intend to have a trial in the press."

Blecher said he has known Sterling since the early `80s, when he helped resolve a dispute that allowed the Clippers to move from San Diego to Los Angeles. Sterling has owned the Clippers since 1981.

Sports Illustrated reported the letter to NBA executive vice-president and general counsel Rick Buchanan said Sterling would not pay the fine because it violated his right to due process.

It also says the controversy "will be adjudicated", according to the report.

The person who spoke to AP said if Sterling doesn't pay the fine, the league could withhold $2.5 million from the Clippers when disbursing money to teams.

The league's Advisory/Finance Committee met via conference call as recently as Tuesday, according to league spokesman Mike Bass.

"The committee discussed the recent media appearances by Donald Sterling and Shelly Sterling, received updates on the hiring of Dick Parsons as the Los Angeles Clippers interim CEO and on his meeting yesterday with Clippers employees, and reviewed the status of the charge for termination of the Clippers' ownership," he said in a brief statement.

Bass said the committee will reconvene this week.

The NBA's constitution, which Sterling signed as controlling owner of the Clippers, gives its board of governors broad latitude in league decisions, including who owns the teams. Article 13 (d) of the constitution says that an owner cannot "fail or refuse to fulfill" contractual obligations to the NBA "in such a way to affect the Association or its members adversely".

Sterling has said he does not want to sell the Clippers. His estranged wife, Shelly, has said she would like to keep her stake in the team even if her husband is ousted.

The Clippers were eliminated from the NBA playoffs on Thursday night after a 104-98 loss to the Oklahoma City Thunder in the Western Conference semifinals.
