The Governor and other elective state officers, including the Justices of the Supreme Court, shall be liable and subject to impeachment for wilful neglect of duty, corruption in office, habitual drunkenness, incompetency, or any offense involving moral turpitude committed while in office. All elected state officers, including Justices of the Supreme Court and Judges of the Court of Criminal Appeals, shall be automatically suspended from office upon their being declared guilty of a felony by a court of competent jurisdiction and their pay and allowances, otherwise payable to such official, shall be withheld during the period of such suspension. In the event such verdict of guilty is reversed by a court of competent jurisdiction on appeal, such accumulated pay and allowances which have been withheld shall be paid to such official and he shall be automatically reinstated in office to serve the remaining part of the term for which he was elected. Such official shall not be entitled to any pay or allowances for a period of time after the term of office would otherwise have expired and he shall not be entitled to reinstatement in office after the expiration of the term for which he was elected. Whenever any Justice of the Supreme Court or Judge of the Court of Criminal Appeals is suspended by reasons of this section, the Governor shall be authorized to appoint a temporary Justice or Judge to serve during the period of such suspension and such temporary Justice or Judge shall be paid for his services the compensation allowed for such regular Justice or Judge.
