(1) The members of the board to be appointed after December 2, 1948, shall be appointed for terms beginning January 15, 1949, and expiring as follows: One member of the board for a term of three years from January 15, 1949; one member of the board for a term of six years from January 15, 1949; and one member of the board for a term of nine years from January 15, 1949. Each of the members of the board appointed hereunder shall hold office until his or her successor is appointed and qualified. After June 11, 1986, the term that began on January 15, 1985, will end on January 15, 1989, the term beginning on January 15, 1988, will end on January 15, 1993, and the term beginning on January 15, 1991, will end on January 15, 1997. Thereafter, upon the expiration of the term of any member appointed after June 11, 1986, each succeeding member of the board shall be appointed and hold office for the term of six years. In case of a vacancy, it shall be filled by appointment by the governor for the unexpired portion of the term in which said vacancy occurs. No vacancy in the membership of the board shall impair the right of the remaining member or members to act, except as herein otherwise provided.

(2) The principal office of the board shall be at the state capitol, and it may establish such other offices as it may deem necessary.

(3) Any member of the board may be removed for inefficiency, malfeasance, or misfeasance in office, upon specific written charges filed by the governor, who shall transmit such written charges to the member accused and to the chief justice of the supreme court. The chief justice shall thereupon designate a tribunal composed of three judges of the superior court to hear and adjudicate the charges. Such tribunal shall fix the time of the hearing, which shall be public, and the procedure for the hearing, and the decision of such tribunal shall be final and not subject to review by the supreme court. Removal of any member of the board by the tribunal shall disqualify such member for reappointment.

(4) Each member of the board shall devote his or her entire time to the duties of his or her office and no member of the board shall hold any other public office. Before entering upon the duties of his or her office, each of said members of the board shall enter into a surety bond executed by a surety company authorized to do business in this state, payable to the state of Washington, to be approved by the governor in the penal sum of fifty thousand dollars conditioned upon the faithful performance of his or her duties, and shall take and subscribe to the oath of office prescribed for elective state officers, which oath and bond shall be filed with the secretary of state. The premium for said bond shall be paid by the board.
