In August, Jeanie Buss took the fight over the Los Angeles Lakers’ future to court, filing a petition to stop her siblings from selling their family’s remaining 17.82% ownership stake in the franchise to Bob Iger and Josh Kushner.

Iger and Kushner purchased the Lakers from Mark Walter at a record-setting $12.5 billion.

On Wednesday, Buss' siblings—Jim Buss, Johnny Buss, Janie Buss, Joey Buss, and Jesse Buss—submitted their opposition, calling her petition “legally and factually baseless,” as reported by ESPN's Shams Charania and Dave McMenamin.

“While discussions among the siblings continue, their focus remains on facilitating the proposed transaction and the trust’s participation in it, while ensuring that all beneficiaries, including Jeanie, are treated equally,” read the statement.

“Today’s filing is a necessary step to protect those interests and ensure the transaction proceeds on schedule.”

Jeanie, 65, claimed that the proposed transaction violates the terms of the family trust and a court order designed to preserve her position as the Lakers' controlling owner.

Her siblings, however, refuted that in their 36-page rebuttal, stressing that the court order named Joey and Janie as co-trustees along with Jeanie.

“They argue the 2017 order requiring the trustees to take reasonably available actions to maintain Jeanie as controlling owner did not limit the beneficiaries' separate rights to terminate the trust. Neither the stipulation nor the order addresses the termination provision they are exercising now,” wrote Charania and McMenamin.

Jeanie had a deal with Walter, who bought the Lakers in October 2025, that she would maintain her post as team governor for five years. Following their acquisition of the team, Iger and Kushner honored the agreement, stressing their respect for the Buss family.
