After the cancellation or revocation of a permit or during the period of its suspension, it is unlawful for a household goods carrier to conduct any operations as such a carrier. The commission may either grant or deny an application for a new permit whenever it appears that a prior permit of the applicant has been canceled or revoked pursuant to Section 5285, or whenever it appears, after hearing, that as a prior permit holder, the applicant engaged in any of the unlawful activities set forth in Section 5285 for which his permit might have been canceled or revoked.
