Is there any case law in which a prison officer has been found to have violated a prisoner's right to due process?

Finley claims that his right to due process was violated in the course of his placement in administrative segregation following a disciplinary hearing and in his transfer to a protective segregation unit. Finley received notice of the alleged disciplinary violation, was afforded a hearing at which he was allowed to contest the charges, and was provided with a written statement of the evidence relied upon to justify his placement in administrative segregation. Similarly, prior to his transfer to the protective segregation unit, he was given a hearing and an opportunity to be heard. In so doing, the prison officials satisfied the requirements of due process. See McFarland v. Cassady, 779 F.2d 1426, 1427 (9th Cir.1986).
