Lawyers for Bill Cosby are urging a court to reseal the actor's deposition testimony about extramarital affairs, Quaaludes and payments to women.
Cosby doesn't want the decade-old testimony used in the legal battles he's fighting with women who accuse him of sexual assault or defamation.
A federal appeals court in Philadelphia is hearing arguments Wednesday.
The 78-year-old Cosby hopes to overturn a ruling that made the documents public last year at the request of The Associated Press.
The AP argues that the issue is now moot given the widespread news coverage that ensued.
Cosby admits to several affairs in the deposition and says he obtained prescription sedatives to give to women he hoped to seduce.
The deposition stems from a lawsuit filed by the accuser at the center of his pending criminal case.
