(b) A Certificate (Casualty) may be denied, revoked, suspended, or modified for any of the following reasons:
(2) Circumstances whereby the party does not qualify as financially responsible in accordance with the requirements of the Commission;
(3) Failure to comply with or respond to lawful inquiries, rules, regulations, or orders of the Commission pursuant to the rules of this subpart.
(c) If the applicant, within 20 days after notice of the proposed denial, revocation, suspension, or modification under paragraph (b) of this section, requests a hearing to show that such denial, revocation, suspension, or modification should not take place, such hearing shall be granted by the Commission.
