Ghislaine Maxwell is now taking her case to the U.S. Supreme Court, seeking to have her sex trafficking conviction thrown out.

Bloomberg — Lawyers for British socialite Ghislaine Maxwell said they asked the US Supreme Court to overturn her 2021 sex-trafficking conviction, arguing she was shielded from prosecution under a deal her former boyfriend Jeffrey Epstein reached with the government in a separate case.

In her petition, which was provided by her lawyer, Maxwell argued she was covered by terms of a 2007 non-prosecution agreement Epstein reached with a US attorney in Florida. Prosecutors agreed not to pursue criminal charges against Epstein or “any potential co-conspirators” in exchange for his guilty plea on state charges he solicited minors to engage in prostitution.

Maxwell is serving a 20-year sentence at a low-security prison in Tallahassee, Florida. During her jury trial in New York, witnesses testified Maxwell lured and groomed underage girls for abuse by Epstein — the disgraced financier who died in jail awaiting trial on sex-trafficking charges — and sometimes participated in the assaults herself.

A copy of Maxwell’s petition was provided by her lawyer, David Markus, who said it was submitted Thursday. The document wasn’t immediately visible on the Supreme Court’s website. The Supreme Court clerk’s office typically takes a few days to formally docket a new appeal.

Last year, a federal appeals court in Manhattan rejected Maxwell’s argument that she was covered by Epstein’s Florida deal. Marcus said the high court should review the case because federal appeals courts are divided on how non-prosecution agreements should apply to co-conspirators. At the time of Epstein’s case in Florida, Maxwell wasn’t charged, but she was considered a potential co-conspirator in the criminal probe.
