The Cosby Show star is due to be quizzed about allegations he acted inappropriately with Judy Huth during a party at the Playboy Mansion in California in 1974, when she was just 15.

Cosby's legal team recently filed sanctions to have the case dismissed on the grounds that Huth filed improperly in December (14), arguing she failed to include two required certificates of merit and listed the 78 year old by name, which his attorneys claim violates a California code.

Cosby will be deposed on Friday, but the judge has yet to rule on the actor's request to have a protective order issued to keep his testimony sealed.

The comedian is facing allegations of decades-old sexual abuse from 50-plus women who have gone public, although many of the claims cannot be pursued in criminal court due to the statute of limitations, which has long expired. Cosby, whose attorneys maintain their client is innocent, has never been charged of any crime related to the reported encounters, although he settled one civil suit with Andrea Constand in 2006.
