If, after receiving notice, a party fails to attend a prehearing conference, hearing, or other scheduled proceeding, the EMS Board may issue a final decision or the administrative law judge may issue a proposed decision, as appropriate, against the defaulting party. Within 7 days after service of a default order, the party may file a written motion: Requesting that the default order be vacated or modified; and Stating the grounds for the request. If the EMS Board or administrative law judge, as appropriate, finds that there is a substantial and sufficient basis for an actual controversy on the merits and that there is good cause to excuse the default, the EMS Board or administrative law judge, as appropriate, may vacate the default order. A final default order is: A final decision; and Reviewable as a final decision.
