The presiding officer may resolve preliminary procedural
motions by telephone conference in which all parties have an opportunity to
participate. Other telephone proceedings or interactive video proceedings,
including the hearing for the contested case proceeding, may be held with the
consent of all parties. The presiding officer will determine the location of
the parties and witnesses for telephone hearings. The convenience of the
witnesses or parties, as well as the nature of the case, will be considered
when location is chosen. The cost of the telephone hearing or an interactive
video hearing may be assessed equally to each party.
