Kobe Bryant is playing some of his toughest defense yet, demanding his mother keeps her hands off his merchandise.

Bryant, the Los Angeles Lakers guard, said 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 - from high school jerseys to trophies and championship rings - can be auctioned off.

Pamela Bryant said 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 son wrote to the auction house demanding it cease the June sale. Goldin is suing to assert its right to sell.
