When a party fails to comply with an order of a Judge or these rules, except as provided in paragraph (b) of this section, an order to show cause shall be directed to the party before the entry of any order of default or dismissal. The order shall be mailed by registered or certified mail, return receipt requested.

(b) Failure to attend hearing. If a party fails to attend a scheduled hearing, the Judge, where appropriate, may find the party in default or dismiss the proceeding without issuing an order to show cause.
