(A) Upon written motion of any representative of record, and upon service of that motion to all other representatives, the attorney hearing examiner may order that the testimony of a witness be taken by deposition in lieu of live testimony under such conditions and terms as the attorney hearing examiner shall set, and that any designated books, papers, documents or tangible objects, not privileged, be produced at the same time and place if it appears probable that:
(1) The witness will be unavailable to attend or will be prevented from attending a hearing; and
(2) The testimony of the witness is material; and
(3) The testimony of the witness is necessary in order to prevent a failure of justice.
In the case of an expert witness, a showing of the unavailability of the expert shall not be necessary for the attorney hearing examiner's consideration of the motion of a representative to take a deposition in lieu of live testimony.
(B) The representatives shall agree to the time and place for taking the deposition in lieu of live testimony. Depositions shall be conducted in the same county in which the hearing is conducted unless otherwise agreed to by the representatives. If the representatives are unable to agree, the attorney hearing examiner shall set the time or fix the place of deposition. At a deposition taken pursuant to this rule, representatives shall have the right, as at hearing, to fully examine witnesses. The attorney hearing examiner has the discretion to be present at the deposition in lieu of testimony at hearing.
(C) A deposition taken under this rule shall be filed with the board not later than one day prior to hearing, and shall be offered into evidence at hearing by the representative requesting the deposition, in lieu of the witness' live testimony at hearing. The cost of preparing a transcript of any testimony taken by deposition in lieu of live testimony shall be borne by the board. In the event of appeal, such costs shall be made a part of the cost of the hearing record. The expense of any video deposition shall be borne by the requestor.
(D) Any deposition or transcript of prior testimony of a witness may be used for the purpose of refreshing the recollection, contradicting the testimony or impeaching the credibility of that witness. If only a part of a deposition of prior testimony is offered into evidence by a representative, the opposing representative may offer any other part. Nothing in this paragraph shall be construed to permit the taking of depositions for purposes other than those set forth in paragraph (A) of this rule.
A transcript of testimony and exhibits from a prior proceeding may be introduced for any purpose if that prior proceeding forms the basis for the allegations in the current case. Upon offering part of a transcript or exhibit from a prior proceeding, the offering representative may be required by the opposing representative to present any other part of the offered item which should in fairness be considered contemporaneously with it.
