Whenever the Governor is of the opinion that any such officer, commissioner or deputy has been or is guilty of misconduct, material neglect of duty or incompetence in the conduct of his office, he shall transmit all facts and information in his possession relating thereto to the Attorney General, who shall thereupon make such investigation as he deems proper, and shall prepare a statement in writing of the charges against such officer, commissioner or deputy, together with a citation, in the name of the state, commanding him to appear before the Governor at a date named therein and show cause, if any there be, why he should not be removed from office as provided in this section. The Attorney General shall cause a copy of such statement and citation to be served, by some proper officer or indifferent person, upon such officer, commissioner or deputy and shall cause a copy thereof, together with a return of the service by the officer or indifferent person making the same endorsed thereon, to be filed in the office of the Secretary. Such officer, commissioner or deputy shall have the right to appear with counsel and witnesses and be fully heard. To carry into effect the proceedings authorized by this section, the Attorney General shall have power to summon witnesses, require the production of any necessary books, papers or other documents and administer oaths to witnesses, and, upon the date named in such citation for the appearance of such officer, commissioner or deputy or at any adjourned date fixed by the Governor, shall appear and conduct the hearing on behalf of the state. He shall cause all oral evidence submitted at such hearing to be reported by a competent stenographer and for such purpose may employ such stenographer at the expense of the state, and, within fifteen days after the close of any such hearing, he shall cause a certified copy of such evidence to be filed with the Secretary. After a full hearing of all the evidence offered by the Attorney General and by or on behalf of any such officer, commissioner or deputy, the Governor shall make a written statement of the facts which he finds to have been proven, and shall, within a reasonable time, file a copy of such finding, duly attested by him, with the Secretary. If the Governor finds that the evidence warrants the removal of such officer, commissioner or deputy from office, he shall make a written order to that effect, and shall cause a copy thereof to be left with or at the usual place of abode of such officer, commissioner or deputy and shall also file a copy thereof with the Secretary. Upon the filing of such copy with the Secretary, the office held by such officer, commissioner or deputy shall become vacant, and the Governor shall thereupon proceed to fill or cause to be filled such vacancy in the manner provided by law. Any witness summoned and any officer or indifferent person making service under the provisions of this section shall be allowed and paid by the state the same fees as are allowed by law in criminal prosecutions.
