R20-5-125. Carrier or Workers’ Compensation Pool Determinations Binding upon its Insured or Member

A. The Commission deems a carrier or workers’ compensation pool the agent of an employer insured by the carrier or workers’ compensation pool. B. The Commission also deems any action or determination taken or made by the carrier or workers’ compensation pool binding upon the employer. The employer may not protest or petition the Commission for relief concerning an action or determination taken by the employer’s carrier or workers’ compensation pool unless the employer notifies the carrier or workers’ compensation pool, and the Commission in writing that the employer disagrees with the carrier’s or worker’s compensation pool’s action or determination within the time described in A.R.S. § 23-947.
