N.C. Gen. Stat. § 58-2-80

Any order or decision of the Commissioner that the premium rates charged or filed on all or any class of risks are excessive, inadequate, unreasonable, unfairly discriminatory or are otherwise not in the public interest or that a classification or classification assignment is unwarranted, unreasonable, improper, unfairly discriminatory or not in the public interest may be appealed to the North Carolina Court of Appeals by any party aggrieved thereby. Any such order shall be based on findings of fact, and if applicable, findings as to trends related to the matter under investigation, and conclusions of law based thereon. Any order or decision of the Commissioner, if supported by substantial evidence, shall be presumed to be correct and proper. For the purposes of the appeal the Insurance Commissioner, who shall be represented by his general counsel, shall be deemed an aggrieved party.
