LOS ANGELES — Jeanie Buss is taking her siblings to court. Again.

Attorneys representing the Lakers’ controlling governor filed a petition in Los Angeles Superior Court on Wednesday to block her five siblings from trying to sell the family’s remaining 17.8% of the NBA franchise the Buss family has owned since 1979.

Jeanie contends that her siblings should abide by a 2017 court order that mandated the family’s co-trustees to “take all actions reasonably available to ensure that Jeanie is appointed and remains as the NBA controlling owner of the Lakers.” The 2017 legal battle installed Jeanie’s younger siblings Janie and Joey as her fellow co-trustees, two roles that were previously held by her older brothers Jim and Johnny, who were ousted after a failed attempt to wrestle control away from Jeanie.

The 97-page petition accuses Janie, Joey and the other siblings Jim, Johnny and Jesse of “devious behavior” for not including Jeanie in discussions to sell the family’s last stakes in the team earlier this month. While the other siblings elected to sell soon after Bob Iger and Joshua Kushner agreed to a record-breaking transaction with Mark Walter and released a statement attributed to the Buss family, Jeanie “never agreed to any sale, was never consulted and was never even informed,” the petition states.

Among five points on the petition, Jeanie hopes to declare her siblings’ votes to sell the team void, remove Janie and Joey as co-trustees for “breach of fiduciary duty” and hold both in contempt of court and hold Jim, Johnny and Jesse in contempt and liable for “aiding and abetting.”

Jeanie, the third-oldest child of former Lakers owner Jerry Buss, was hand-picked by the family patriarch to oversee his prized investment that grew from a $67.5-million purchase into a $12.5 billion world-renowned brand. Iger, the former Disney chief executive, and Kushner, founder of a venture capital firm, bought a majority stake of the Lakers from Walter earlier this month at a record valuation, and reports of five of the Buss siblings’ plans to sell their ownership stake in the team came days later.

To remain on the NBA board of governors, Jeanie would need to own at least 15% of the team. She was to stay in the leadership role for at least the next four seasons after the Buss family relinquished control of the team to Walter in 2025.
