The entertainer is nixing a request by lawyers for Autumn Jackson to submit to a paternity test to determine if he's Jackson's biological father.
Jackson, of Los Angeles, faces charges in federal court in New York that she tried to squeeze $40 million from everybody's favorite TV dad by threatening to go to the tabloids with a juicy story that she's Cosby's illegitimate daughter.
Three others have also been indicted in the alleged scheme.
Cosby has admitted having an affair with Jackson's mother 23 years ago--an unnamed woman who now lives in Canyon Country, California. He's even allowed for the "possibility" that he is Jackson's dad.
But an attorney for Cosby says paternity is not the issue in the extortion trial. Andrew Schau accuses Jackson's side of trying "to create distractions."
Prosecutors agree with Schau, and have asked a federal judge to ban the defense from quizzing Cosby about paternity--as well as his net worth--when the sitcom star testifies.
Robert Baum, Jackson's attorney, months ago vowed to prove in court that his client was Cosby's daughter. He also wants to show that Cosby acted like a parent to the young woman.
Cosby, who turns 60 next week, financially supported Jackson through her school years. Last winter, according to prosecutors, the actor/comedian's lawyer got a call from Jackson, saying she was out of money. She received some $3,000.
Then, federal authorities say, the extortion plot began. By mid-December, Jackson and an associate, wannabe screenplay writer Jose Medina, 51, allegedly were asking for $40 million--or else. They later downsized to $24 million, and were arrested by FBI agents after they accepted checks for that amount, prosecutors say.
The arrests came down in January, mere days after Cosby's only son, Ennis, was shot to death on the roadside of a Los Angeles freeway. It's been reported that Jackson faxed over one of her multimillion-dollar demands on the very day of the murder--January 16.
There's no connection between the extortion and Ennis Cosby cases. Ennis Cosby's accused killer, Mikhail Markhasev, faces life in prison on the murder charges facing him. Police say robbery was the motive in the random slaying.
Jury selection in the trial of Autumn Jackson is scheduled to begin next Monday.
