(1) When a party to these proceedings has, after notice, failed to attend a hearing and has not notified the board and the opposing party of the intention to not attend, a motion for default or dismissal may be sought by any party to the proceedings, or raised by the board upon its own motion. Any such order shall include a statement of the grounds for the order and shall be served upon all parties to the proceeding.

Within ten business days after service of the default order or dismissal under subsection (1) of this section, the party against whom the order was entered may submit to the board together with proof of service pursuant to WAC 458-10-410 [ 456-10-410] a written objection requesting that the order be vacated and stating the specific grounds relied upon. The board may, for good cause, set aside an entry of dismissal, default, or final order.

(2) Upon stipulation by both parties, an appeal may be submitted to the board on the record and attendance of a party may be excused. However, the board in its discretion may require attendance for argument.
