When entering a plea for each inmate rule violation charged, the defendant may enter only one of the following for each inmate rule violation charged: Guilty; Not Guilty; Not Competent; or No plea. Guilty Plea. If the defendant enters a guilty plea to the inmate rule violation charged, the hearing officer, before accepting the guilty plea, shall determine the defendant understands that the guilty plea is: A waiver by the defendant of the inmate disciplinary process and appeal rights; An admission by the defendant that the defendant committed the inmate rule violation charged; and An affirmation that the defendant’s guilty plea is voluntary. If the hearing officer accepts the plea of guilty, the hearing officer shall proceed to the sanction phase of the defendant’s disciplinary proceeding.
