Bill Cosby's name has been removed from a sexual assault lawsuit filed by California woman Judy Huth due to a paperwork error.

Huth's lawyer filed a civil suit against the embattled comedian last week (02Dec14), accusing him of getting her drunk and then raping her during a party at the Playboy Mansion in Los Angeles in 1974, when she was 15.

Cosby, 77, hit back at the accusations and filed a countersuit, demanding the case be dismissed after insisting Huth is a liar who attempted to extort him and then raised the price for her silence as more women came forward with assault claims.

And now it appears Cosby has won a small battle in the case as Huth's court papers should not have named her alleged attacker as, under California law, the defendant must only be referred to as John Doe to prevent an unfair public judgement in the event of a bogus claim, according to Tmz.com.

Huth's lawyer, Marc Strecker, has since amended the documents and refiled them.

It's a little too late to protect Cosby's reputation, which has taken a huge hit in recent weeks - more than 20 women have come forward with historic claims of abuse against the veteran comedian.

Cosby's attorneys have slammed the growing list of allegations, which have cost the troubled star a number of gigs on his current comedy tour and a series of high-profile posts.
