No policy of insurance against liability arising under the Nebraska Workers’ Compensation Act shall be issued and no agreement pursuant to section 44-4304 providing group self-insurance coverage of workers’ compensation liability by a risk management pool shall have any force or effect unless it contains the agreement of the workers’ compensation insurer or risk management pool that it will promptly pay to the person entitled to the same all benefits conferred by such act, and all installments of the compensation that may be awarded or agreed upon, and that the obligation shall not be affected by the insolvency or bankruptcy of the employer or his or her estate or discharge therein or by any default of the employer after the injury, or by any default in the giving of any notice required by such policy, or otherwise. Such agreement shall be construed to be a direct promise by the workers’ compensation insurer or risk management pool to the person entitled to compensation enforceable in his or her name. Each workers’ compensation insurance policy and each agreement forming a risk management pool shall be deemed to be made subject to the Nebraska Workers’ Compensation Act. No corporation, association, or organization shall enter into a workers’ compensation insurance policy unless copies of such forms have been filed with and approved by the Department of Insurance. Each workers’ compensation insurance policy and each agreement pursuant to section 44-4304 providing group self-insurance coverage of workers’ compensation liability by a risk management pool shall contain a clause to the effect (1) that as between the employer and the workers’ compensation insurer or risk management pool the notice to or knowledge of the occurrence of the injury on the part of the employer shall be deemed notice or knowledge, as the case may be, on the part of the insurer or risk management pool, (2) that jurisdiction of the employer for the purpose of such act shall be jurisdiction of the insurer or risk management pool, and (3) that the insurer or risk management pool shall in all things be bound by the awards, judgments, or decrees rendered against such employer. Except when the Professional Employer Organization Registration Act allows coverage to be limited to co-employees as specified in a professional employer agreement, each workers’ compensation insurance policy and each agreement providing such group self-insurance coverage shall include within its terms the payment of compensation to all employees who are within the scope and purview of the Nebraska Workers’ Compensation Act, including potential new or unknown employees.
