Wash. Rev. Code § 15.89.060
Obligations incurred by the commission and any other liabilities or claims against the commission shall be enforced only against the assets of the commission and, except to the extent of such assets, no liability for the debts or actions of the commission exists against either the state of Washington or any subdivision or instrumentality thereof or against any member, employee, or agent of the commission or the state of Washington in his or her individual capacity. Except as otherwise provided in this chapter, neither the commission members, nor its employees, may be held individually responsible for errors in judgment, mistakes, or other acts, either of commission or omission, as principal, agent, person, or employee, except for their own individual acts of dishonesty or crime. No person or employee may be held individually responsible for any act or omission of any other commission members. The liability of the commission members shall be several and not joint, and no member is liable for the default of any other member. This provision confirms that commission members have been and continue to be, state officers or volunteers for purposes of RCW 4.92.075 and are entitled to the defenses, indemnifications, limitations of liability, and other protections and benefits of chapter 4.92 RCW.
