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 the original of such written charges to the chief justice of the supreme court and a copy thereof to the member accused.

Such tribunal shall fix the time, place and procedure for the hearing, and the hearing shall be public. The decision of such tribunal shall be final and not subject to review.
