Bill Cosby has petitioned a Los Angeles Superior Court in hopes of permanently dropping an ordered deposition hearing in the defamation suit filed against him by former supermodel Janice Dickinson.

According to Deadline, attorneys for Cosby filed legal documents on Monday seeking to have the hearing all but vacated, on the grounds "The Cosby Show" dad's former attorney Martin Singer did not defame Dickinson.

Initially, Cosby and Singer were both scheduled to submit to interrogations earlier this month in the suit filed by the former "America's Next Top Model" judge. The defamation allegation stems from Singer branding Dickinson a "liar," after she again recently went public with claims Cosby sexually assaulted her more than 40 years ago.

"The undeniable fact is that Plaintiff s public statements in her autobiography flat-out contradict her more recent public statements," the filing stipulates.

In more recent statements and in her lawsuit filed more than six months ago, Dickinson claimed she was pressured by publisher HarperCollins to omit the episode from her 2002 book out of fear of legal action.

In all, more than 50 women have stepped forward to claim they were drugged and sexually assaulted by the now 78-year-old old Cosby over a period that spans more than four decades.

Cosby has denied all the allegations and has never faced criminal charges stemming from any of the alleged incidents. Earlier this year, he was actually forced to give testimony at a deposition hearing stemming from yet another defamation hearing, which was filed against him by former Playboy bunny Judy Huth.

Famed civil rights attorney Gloria Allred grilled Cosby for more than seven hours in proceedings that were held in Boston. Huth alleges she too was drugged and sexually assaulted by Cosby at the Playboy mansion more than 40 years ago and when she was just 15 years old.

Allred has already petitioned the court for a second opportunity to interrogate the famed comedian.
