Rule 3746-7-09 | Evidence.
(A) A party may object to the admission of any evidence, and the commission shall rule on the objection. If the commission refuses to admit evidence, the party offering the same may make a proffer thereof, and such proffer shall be made a part of the record of the hearing.
(B) Parties shall have the right to present evidence, cross-examination, objection, motion, and argument. The commission may limit the number of witnesses upon any issue and may require any party to present additional evidence on any issue. All witnesses shall be sworn or shall affirm the truthfulness of their testimony.
(C) Written testimony (on numbered lines in either narrative or question-and-answer form) of any witness may be admitted into evidence, provided the witness is present and sworn or affirmed. A copy of the testimony shall be served upon and received by all other parties at least three days prior to the hearing.
(D) Copies of any exhibit to be offered into evidence shall be provided to each commission member and all parties at the time it is identified as an exhibit, unless otherwise ordered by the commission.
(E) If any person objects to the admission or rejection of any evidence or to other limitations of the scope of any examination or cross-examination, the party shall state briefly the grounds for such objection on the record. A ruling by the commission on any such objection shall also be a part of the record.
