The law firm whose attorneys were sanctioned by a federal judge for fraudulently filing dozens of copyright infringement cases against people accused of downloading pornographic films has voluntarily dissolved after posting more than $237,000 in bonds in the case.

U.S. District Judge Otis Wright on May 6 sanctioned four lawyers associated with Chicago’s Prenda Law Inc., concluding that they “suffer from a form of moral turpitude unbecoming of an officer of the court.” He referred the attorneys to licensing authorities for possible misconduct and to federal prosecutors for possible criminal violations of the U.S. Racketeer Influenced and Corrupt Organizations Act.
