1. If the Commissioner finds that:
(a) The interaction among insurers is not competitive;
(b) The rates filed by insurers whose interaction is competitive are inadequate or unfairly discriminatory; or
(c) The rates violate the provisions of this chapter,
Ê the Commissioner may require the insurers to file information supporting their existing rates. Before the Commissioner may disapprove those rates, the Commissioner shall notify the insurers and hold a hearing on the rates and the supplementary rate information.
2. The Commissioner may disapprove any rate without a hearing. Any insurer whose rates are disapproved in this manner may request in writing and within 30 days after the disapproval that the Commissioner conduct a hearing on the matter.
