(1) If a party fails to attend or participate in a hearing or other stage of an adjudicative proceeding, the administrative law judge may serve upon all parties a default order with a statement of the grounds for the order.

(2) Within seven days after service of a default order under subsection (1) of this section, the party against whom the default order was entered may file a written motion to the administrative law judge requesting that the order be vacated and stating the grounds relied upon. The administrative law judge will set aside an order of default only upon a showing of good and sufficient cause for such failure to appear or to request a postponement prior to the scheduled time for hearing. In the event such order of default is set aside, all interested parties shall be so notified in writing and the matter restored to the hearing calendar.
