Jeanie Buss said her brother Jim was “completely unfit” to run the team’s basketball operations in a document filed Friday in Los Angeles County Superior Court.

“I must also point out that Jim has already proven to be completely unfit even in an executive vice president of basketball operations role and I recently had to replace him,” Jeanie Buss said in the document.

Last month, Jeanie Buss fired Jim Buss and installed Magic Johnson as president of basketball operations, part of wide-ranging changes in the front office.

“Despite the fact that I gave my brother Jim ample time to prove himself in his role … I could not allow the damage being done to the franchise over the past few years to continue,” the declaration said.

Jeanie Buss also expressed concern in the declaration that if the brothers chose a new controlling owner, the person would fire Johnson and “cause irreversible damage to the Lakers team and to the brand.”
