There is no liability on the part of, and no cause of action of any nature may arise against, any member insurer or its agents or employees, the association's agents or employees, members of the board of directors, or the director or his representatives for any action taken or omission by them in the authorized performance of their powers and duties under this chapter. This section does not relieve the association of any of its statutory obligations. The immunity extends to the participation in an organization of one or more state associations of similar purposes and to such organization, its agents, and employees.
