Except as provided in subsection (b) of this section, if the Commission pays a claim against the Fund based on an act or omission of a contractor, the Commission may suspend the contractor license until the contractor reimburses the Fund in full for: the amount paid from the Fund; and interest on that amount at an annual rate of at least 10%, as set by the Commission. The Commission may not suspend the contractor license if the Commission finds that the contractor or management personnel of the contractor: did not know of the wrongful conduct; or could not prevent the violation. Reimbursement of the Fund in full by a contractor, by itself, does not nullify or modify the effect of a disciplinary proceeding against a licensee.
