Insurance Code (usually included in commercial codals)
Section 358. Whenever the Commissioner shall determine, after notice and a hearing, that the rates charged or filed on any class of risks are excessive, discriminatory, inadequate or unreasonable, he shall order that such rates be appropriately adjusted. For the purpose of applying the provisions of this section, the Commissioner may from time to time approve reasonable classifications of risks for any or all such classes, having due regard to the past and prospective loss experience, including conflagration or catastrophe hazards, if any, to all other relevant factors and to a reasonable profit.
