The Seventh Circuit has held that misinformation by the sentencing court regarding the mandatory parole provision in the plea bargain violated due process. See Ferris v. Finkbeiner, 551 F.2d 185 (7th Cir. 1977) (holding defendants due process rights were violated when in the course of making a plea agreement the court misinformed him that he would not have to serve mandatory five-year parole term).
