(a) Evidence Generally. Evidence, including hearsay evidence, shall be admitted if it is relevant and if in the judgment of the hearing officer it is the kind of evidence on which reasonably prudent persons are accustomed to rely in the conduct of their affairs. However, the hearing officer may exclude evidence if its probative value is outweighed by the danger of unfair prejudice, by confusion of the issues, or by reasonable concern for undue delay, waste of time, or needless presentation of cumulative evidence.
(b) Exchange of Exhibits. To be considered as evidence in a decision, any document or physical evidence must be entered as an exhibit at the hearing. Any documentary evidence to be presented during a telephonic hearing shall be exchanged with all parties and a copy shall be provided to the hearing officer in advance of the hearing. Any documentary evidence to be presented at an in-person hearing shall be exchanged at the hearing.
(c) Stipulations. The parties, with the consent of the hearing officer, may agree in writing to relevant facts. The hearing officer may decide the appeal on the basis of such stipulations or, at the hearing officer's discretion, may set the appeal for hearing and take such further evidence as the hearing officer deems necessary.
(d) Experts and Evaluations. If relevant and useful, testimony from an independent expert or a professional evaluation from a source satisfactory to the parties and the Agency may be ordered by hearing officers, on their own motion or at a party's request. The cost of any such expert or evaluation ordered by the hearing officer shall be borne equally by the parties.
(e) Subpoenas.
  (1) The hearing officer may issue subpoenas to compel the attendance of witnesses and the production of records. A subpoena may be issued either at the request of a party or on the hearing officer's own motion.
  (2) A party requesting a subpoena shall state the nature of the information desired, including names of any witnesses and the records that the requestor feels are necessary for the proper presentation of the case.
  (3) The request shall be granted only to the extent the records or the testimony of the requested witnesses appears to be relevant to the issues on appeal.
  (4) A denial of a subpoena request shall be made in writing or on the record, stating the reasons for such denial.
