^9. The Wolff procedural due process requirements are: (1) advance, written notice of violation; (2) provision of at least 24 hours to prepare for committee appearance; (3) written statement of fact-finding; (4) the right to present witnesses and evidence where it would not be unduly hazardous to institutional safety; (5) an impartial decision-making body, and (6) assistance if inmate is illiterate or if issues are complex. Wolff, 418 U.S. at 564-70; see generally Hanrahan v. Lane, 747 F.2d 1137, 1140 (7th Cir. 1984). These requirements protect prisoners from "arbitrary actions extinguishing their privileges."
