Section 450.430 Default
Where there has been proper
notice of a hearing, the failure of any party to appear at the appointed time
set for hearing, or the failure of any party to properly plead after due notice
has been given, shall subject the party to be ruled in default by the hearing
officer. Upon good cause being shown, however, within thirty (30) days of the
entry of a default upon any party, the hearing officer, after due consideration
of the grounds excusing the defaulted party, may order the default judgement to
be vacated and set aside, and may order a new hearing.
