N.J. Stat. § 17:29A-10
A member of or subscriber to a rating organization may make a written application to the commissioner for permission to file a uniform percentage decrease or increase to be applied to the premiums produced by the rating system filed on its behalf by such rating organization for a kind of insurance, a subdivision of a kind of insurance or for a class of insurance which is found by the commissioner to be a proper rating unit for the application of such uniform percentage decrease or increase, or otherwise deviate from the rating plans or rules so filed. The commissioner shall, make an order approving the application if he shall deem it consistent with the establishment and maintenance of reasonable, adequate, and nondiscriminatory rates. If the commissioner shall find that such increase or decrease will result in rates that are unreasonable, inadequate, or unfairly discriminatory, he shall make an order denying the application.
