A federal judge today granted law professor Alan Dershowitz’s request to strike allegations of inappropriate sexual conduct from an ongoing lawsuit against convicted sexual offender and former Palm Beach financier Jeffrey Epstein.

The lawsuit, filed in 2008, seeks to undo a non-prosecution agreement between federal prosecutors and Epstein, who the woman said arranged the sex with Prince Andrew and Dershowitz.

Dershowitz has vehemently denied the claims as has the prince. Epstein has called the claims old and discredited.

U.S. District Judge Kenneth Marra in West Palm Beach, Florida, ruled that it was unnecessary for the woman, known in court papers as Jane Doe No. 3, and another known as Jane Doe No. 4, to join the lawsuit at all, and struck down the sexual misconduct allegations.

Dershowitz's representative, in an email to Newsmax, said Dershowitz intervened "for the limited purpose of moving to strike the outrageous and impertinent allegations made against him." By taking it upon itself "to strike the impertinent factual details," the court "sanctioned' the petitioners. The ruling will force "all submissions be presented for a proper purpose and factual contentions have evidentiary support," Dershowitz's representative wrote.

Dershowitz described the ruling as "a vindication of my position and as a caution to attorneys against misusing court pleadings for improper purposes."

Epstein, a financier from New York, pleaded guilty in a Florida state court in 2008 to procuring an underage girl for prostitution. He served a year in jail, and the Justice Department agreed not to bring federal charges.

Marra wrote that he would decide later on the merits of the case, in which two other women, known as Jane Doe Nos. 1 and 2, say federal prosecutors violated their rights as crime victims when signing the deal with Epstein.

The judge wrote that he could still consider relevant evidence from Jane Doe Nos. 3 and 4, but that their participation in the case "as listed parties is not necessary in that regard."

Lawyers for the four women did not immediately respond to a request for comment.

Federal prosecutors, who had opposed the request by Jane Doe Nos. 3 and 4 to join the lawsuit, had no comment on the ruling, a spokeswoman from the U.S. Attorney's Office in Southern Florida said.
