(4) The inmate is entitled to present documentary evidence and to have witnesses appear, provided that calling witnesses would not jeopardize or threaten institutional security or individual safety, and further provided that the witnesses are available at the institution where the hearing is being conducted.
- (i) The evidence to be presented must be material and relevant to the issue as to whether the inmate can and would function in a general prison population without being or posing a threat to staff or others or to the orderly operation of the institution. The Hearing Administrator may not consider an attempt to reverse or repeal a prior finding of a disciplinary violation.
- (ii) Repetitive witnesses need not be called. Staff who recommend placement in a control unit are not required to appear, provided their recommendation is fully explained in the record. Staff who were involved, in any capacity, in former disciplinary proceedings need not be called as to their involvement in those proceedings, since this hearing is not to go over the factual basis for prior actions which have been decided.
- (iii) When a witness is not available within the institution, or not permitted to appear, the inmate may submit a written statement by that witness. The Hearing Administrator shall, upon the inmate's request, postpone any decision following the hearing for a reasonable time to permit the obtaining and forwarding of written statements.
- (iv) The Hearing Administrator shall document in the record of the hearing the reasons for declining to permit a witness or to receive documentary evidence.
