(a) An employer joining a workers' compensation self-insurance group after the group has been issued a certificate of authority shall:
(1) Submit an application for membership to the board of trustees or its administrator; and
(2) Enter into the indemnity agreement required by § 404(b)(5) of this title. Membership takes effect no earlier than each member's date of approval.
The application for membership and its approval shall be maintained as permanent records of the board of trustees.
(b) Individual members of a group shall be subject to cancellation by the group pursuant to the by-laws of the group. In addition, individual members may elect to terminate their participation in the group. The group shall notify the Commissioner and the workers' compensation agency of the termination or cancellation of a member within 10 days and shall maintain coverage of each canceled or terminated member for 30 days after notice, at the terminating member's expense, unless the group is notified sooner by the workers' compensation agency that the canceled or terminated member has procured workers' compensation insurance, has become an approved self-insurer or has become a member of another group.
(c) The group shall pay all workers' compensation benefits for which each member incurs liability during its period of membership. A member who elects to terminate its membership or is canceled by a group remains jointly and severally liable for workers' compensation obligations of the group and its members which were incurred during the canceled or terminated member's period of membership.
(d) A group member is not relieved of its workers' compensation liabilities incurred during its period of membership except through payment by the group or the member of required workers' compensation benefits.
(e) The insolvency or bankruptcy of a member does not relieve the group or any other member of liability for the payment of any workers' compensation benefits incurred during the insolvent or bankrupt member's period of membership.
