What rights does an inmate have at a prison disciplinary hearing?

Prison disciplinary proceedings are not part of a criminal prosecution and the full panoply of rights due a defendant in such proceedings does not apply. Wolff v. McDonnell, 418 U.S. 539, 556 (1974). A prison disciplinary hearing satisfies the Due Process Clause if the inmate is provided with: (1) advance written notice of the disciplinary charges; (2) an opportunity to call witnesses and present documentary evidence in his defense; and (3) a written statement by the factfinder of the evidence relied on and the reason for the disciplinary action. Wolff, 418 U.S. at 563-69; Zimmerlee v. Keeney, 831 F.2d 183, 186 (9th Cir.1987), cert. denied, 487 U.S. 1207 (1988).
