The person presiding at a hearing shall regulate the course of the hearing in conformity with this chapter and any rules adopted under this chapter by an administrative agency, any other applicable laws, and any prehearing order. To the extent necessary for full disclosure of all relevant facts and issues, the person presiding at the hearing shall afford to all parties and other persons allowed to participate the opportunity to respond, present evidence and argument, conduct cross-examination, and submit rebuttal evidence, except as restricted or conditioned by a grant of intervention or by a prehearing order. A hearing may be conducted in total or in part by making use of telephone, television, facsimile services, or other electronic means if each participant in the hearing has an opportunity to participate in, to hear, and, if practicable, to see the entire proceeding while it is taking place, and if such use does not substantially prejudice or infringe on the rights and interests of any party.
