Any employer licensed by the State as a hospital who participates in group self-insurance shall not be relieved from the liability for compensation prescribed by Title 34 of the Revised Statutes except by the payment thereof by the group self-insurer or by himself. The insolvency or bankruptcy of a participating employer shall not relieve the group self-insurer from the payment of compensation for injuries or death sustained by an employee during the time the employer was a participant in such group self-insurance.
