The officers and directors of an insurer violating RCW 48.09.180 shall be jointly and severally liable to the insurer for any excess of expenses incurred. If the insurer fails to exercise reasonable diligence or refuses to enforce such liability, the commissioner may prosecute action thereon for the benefit of the insurer. Such failure or refusal constitutes grounds for revocation of the insurer's certificate of authority.
