Attorneys representing Ghislaine Maxwell, the former British socialite and longtime confidante of Jeffrey Epstein, filed a 102-page brief in the U.S. Court of Appeals for the Second Circuit on Tuesday, arguing that she was prosecuted as a “proxy” for Epstein.

Maxwell was sentenced to 20 years in prison in June, six months after a Manhattan federal jury found her guilty of guilty on five counts, including sex trafficking, conspiracy, enticement and transporting a minor with intent to engage in illegal sex acts.
