According to legal documents obtained by Radar, prosecutors in her sexual assault case are demanding the judge take action against David Oscar Markus.
On Wednesday, Markus wrote an Op-Ed in the New York Daily News declaring Ghislaine should be released from prison because of an alleged technicality, just like Cosby.
"She should not have to fight her case at trial and her case should be thrown out, just like Cosby's has been, because prosecutors promised Epstein when he pleaded guilty that they would not prosecute her," Markus stated in the Op-Ed.
But prosecutors are saying not so fast.
They want U.S. District Judge Alison J. Nathan -- who is presiding over Ghislaine's case -- to force Markus to stop talking.
They argue "not only did his statements directly comment on the merits of this case, but they did so in a manner designed to appeal directly to the pool of potential jurors in this case."
Prosecutors claim Ghislaine's attorney violated the law with his Cosby comparison in the Op-Ed.
They are worried his statements "will interfere with a fair trial or otherwise prejudice the due administration of justice.”
As Radar reported, Pennsylvania Supreme Court decided to overturn Cosby's sexual assault conviction on a legal technicality.
Cosby had been locked up for two years in a state prison near Philadelphia after being found guilty of the sexual assault of former Temple University employee Andrea Constand in 2004.
The star -- formerly known as "America's Dad" -- was convicted on three counts of aggravated indecent assault in 2018. He was sentenced to three to 10-years.
The FBI arrested Ghislaine in July of last year.
She is accused of recruiting, grooming, and trafficking girls and young women for Epstein's sexual pleasure.
Ghislaine has pled not guilty and been denied bail multiple times.
She recently faced another loss when the judge decided several of her private documents will be unsealed. Those documents are expected to reveal juicy details about her relationship with Epstein and former President Bill Clinton.
Ghislaine's trial is scheduled to begin on September 29.
