Attorneys for Keith Raniere, leader of the so-called “sex cult” NXIVM, and his co-defendant, Seagram’s liquor company heiress Clare Bronfman, appeared in the U.S. Court of Appeals for the Second Circuit on Tuesday, nearly two years after they were each sentenced for NXIVM-related acts in the Eastern District of New York.

Raniere’s attorney, Joseph M. Tully of Tully & Weiss Attorneys at Law, asked the three-judge panel to reverse Raniere’s conviction, while Bronfman’s attorney, Harvard Law School professor and Criminal Justice Institute director Ronald S. Sullivan, Jr., asked the court to vacate Bronfman’s sentence.
