§ 4-b. Removals. The governor may remove any public service commissioner, now in office or hereafter appointed, for inefficiency, neglect of duty or misconduct in office, giving him a copy of the charges against him, and an opportunity of being publicly heard in person or by counsel in his own defense, upon not less than ten days' notice. If such commissioner shall be removed the governor shall file in the office of the department of state a complete statement of charges made against such commissioner, and his findings thereon, together with a complete record of the proceeding.
