(c) The Board shall make a determination with regard to the default order promptly after expiration of the time within which the party may file a written objection under subsection (b) of this section.
(d) Upon issuance of a default order, the Board shall conduct, without the participation of the party in default, any further proceedings necessary to complete the contested case and determine all issues in the proceeding, including those affecting the defaulted party.
