What rights does a prisoner have in a disciplinary hearing?

Under the Fourteenth Amendment, no state shall deprive any person of life, liberty, or property without due process of law. Prisoners retain their right to due process subject to the restrictions imposed by the nature of the penal system. Wolff v. McDonnell, 418 U.S. 539, 556 (1974). A prisoner in a prison disciplinary hearing is not entitled to the full array of due process rights that a defendant possesses in a criminal prosecution. Id. at 556. However, a prisoner who is accused of serious rules violations and who may be deprived of his or her good-time credits is entitled to certain minimum procedural protections. Id. at 571-71 n. 9.
