A California attorney sanctioned for his role in a nationwide fraud scheme targeting alleged infringers of pornography copyrights claims that he should be exonerated so that he could testify against his former colleagues.

Brett Gibbs, a solo practitioner in Mill Valley, Calif., was sanctioned on May 6 along with three other attorneys associated with Chicago’s Prenda Law Inc. for creating sham corporations to extort settlements from individuals accused of illegally downloading copyrighted pornographic films. Gibbs filed a motion to vacate the judge’s sanctions order against him, arguing that new evidence shows he knew nothing about his former colleagues’ activities.
