(1) In any case where the employer is not a self-insurer, in order that the liability for compensation imposed by this chapter may be most effectively discharged by the employer and in order that the administration of this chapter with respect to that liability may be facilitated, the Workers' Compensation Commission shall by rule provide for the discharge by the carrier, for the employer, of the obligations and duties of the employer with respect to such liability imposed by this chapter upon the employer as it considers proper in order to effectuate the provisions of this chapter.
(2) For such purpose: Notice to or knowledge of an employer of the occurrence of the injury shall be notice to or knowledge of the carrier;
(3) Jurisdiction over the employer by the commission or by any court under this chapter shall be jurisdiction over the carrier; and
(4) Any requirements by the commission or any court under any compensation order, finding, or decision shall be binding upon the carrier in the same manner and to the same extent as upon the employer.
