Jeanie Buss is taking her siblings to court over the future of the Los Angeles Lakers.

Attorneys for the team's controlling governor filed a 97-page petition in Los Angeles Superior Court on Wednesday, Aug. 26, seeking to void her five siblings' vote to sell the Buss family's remaining 17.82% stake to new majority owners Bob Iger and Josh Kushner. The petition also demands that co-trustees Joey Buss and Janie Buss be removed for breach of fiduciary duty and held in contempt of a 2017 court order, The Athletic reported.

The filing contains five causes of action. They include instructing trustees to comply with the 2017 order, declaring the siblings' resolution to sell void, surcharging and removing Joey and Janie as co-trustees, holding them in contempt, and holding siblings Jim, Johnny and Jesse Buss liable for aiding and abetting.

"It is beyond regrettable that Jeanie has had to bring this action," attorney Adam F. Streisand told TheWrap on Thursday, Aug. 27.

A court hearing is scheduled for Nov. 5.

What sparked the fight

Five of the six Buss siblings voted to exercise a tag-along provision tied to Mark Walter's sale of his controlling stake, according to the petition. Joey Buss signed a letter to sell on Tuesday, Aug. 11. The five siblings then signed a formal resolution on Tuesday, Aug. 18.

The petition accuses them of "devious behavior" for excluding Jeanie from all discussions. It states she "never agreed to any sale, was never consulted and was never even informed," the Los Angeles Times reported.

Jeanie's legal team argues the siblings must honor the 2017 court order that mandated co-trustees "take all actions reasonably available to ensure that Jeanie is appointed and remains as the NBA controlling owner of the Lakers." That 2017 battle installed Janie and Joey as co-trustees after older brothers Jim and Johnny were ousted for trying to wrestle control from Jeanie.

The financial picture

Jerry Buss bought the Lakers in 1979 for $67.5 million. The franchise is now valued at $12.5 billion under the Iger-Kushner deal. The petition argues selling does not make financial sense given the team's "continuously skyrocketing value."

Minority owners Patrick Soon-Shiong and Ed Roski Jr. have expressed support for Jeanie remaining as controlling owner and have said they do not intend to sell their stakes, according to the OC Register.

If the siblings' sale goes through, Iger and Kushner would own approximately 83% of the team. Jeanie needs at least a 15% stake to remain on the NBA Board of Governors.

The broader sale from Walter to Iger and Kushner is not expected to be affected by the family's legal proceedings, according to a source cited by the Los Angeles Times who was not authorized to speak publicly. The NBA Board of Governors is scheduled to meet Sept. 15-16 in New York, where the Walter-to-Iger/Kushner transaction requires approval. Kushner must also sell his minority stake in the Miami Heat before the deal can clear.

No on-record response from Joey, Jesse, Jim, Johnny or Janie Buss to the Aug. 26 petition has been published.
