Kobe Bryant says in a court filing that he never gave his mother permission to sell mementos from his high school days and early professional basketball career.
Bryant is in a court battle over whether hundreds of items can be auctioned off.
Pamela Bryant says the NBA star told her the memorabilia was hers. She arranged earlier this year to auction it off through Berlin, N.J.-based Goldin Auctions and received a $450,000 advance.
Last week, lawyers for the NBA star wrote to the auction house demanding it cease the June sale. Goldin is suing to assert its right to sell.
In a filing Wednesday in U.S. District Court in Camden, Kobe Bryant says his mother acknowledged to him recently that she did not have permission to sell the items.
