28 CFR 2.50 - Revocation hearing procedure.
(a) The purpose of the revocation hearing shall be to determine whether the parolee has violated the conditions of his release and, if so, whether his parole or mandatory release should be revoked or reinstated.
(b) The alleged violator may present witnesses, and documentary evidence in his behalf. However, the presiding hearing officer or examiner panel may limit or exclude any irrelevant or repetitious statement or documentary evidence.
(c) At a local revocation hearing, the Commission may on the request of the alleged violator or on its own motion, request the attendance of persons who have given statements upon which revocation may be based. Those witnesses who are present shall be made available for questioning and cross-examination in the presence of the alleged violator unless the presiding hearing officer or examiner panel finds good cause for their non-attendance. Adverse witnesses will not be requested to appear at institutional revocation hearings.
(d) All evidence upon which the finding of violation may be based shall be disclosed to the alleged violator at or before the revocation hearing. The hearing officer or examiner panel may disclose documentary evidence by permitting the alleged violator to examine the document during the hearing, or where appropriate, by reading or summarizing the document in the presence of the alleged violator.
(e) In lieu of an attorney, an alleged violator may be represented at a revocation hearing by a person of his choice. However, the role of such non-attorney representative shall be limited to offering a statement on the alleged violator's behalf with regard to reparole or reinstatement to supervision.
