Maxwell, an associate of deceased financier Jeffrey Epstein, was convicted of sex trafficking in 2021.

The Supreme Court said Monday that it would not hear Ghislaine Maxwell’s appeal of her sex-trafficking conviction, declining to consider arguments from the imprisoned associate of deceased financier Jeffrey Epstein that she was improperly prosecuted.

Maxwell, who was convicted in 2021 in New York, has said that under a plea agreement Epstein, her ex-boyfriend, reached years earlier in Florida, federal officials pledged not to prosecute any of his potential co-conspirators, which should have prohibited her case from proceeding.

President Donald Trump’s administration has pushed back on Maxwell’s argument, saying that the deal did not extend to her case.

“We’re, of course, deeply disappointed that the Supreme Court declined to hear Ghislaine Maxwell’s case,” David Oscar Markus, an attorney for Maxwell, said in a statement. “But this fight isn’t over. Serious legal and factual issues remain, and we will continue to pursue every avenue available to ensure that justice is done.”
