Texas Constitution Art. 16 sec. 72 – Temporary Replacement of Public Officer On Active Military Duty
(a) An elected or appointed officer of the state or of any political subdivision who enters active duty in the armed forces of the United States as a result of being called to duty, drafted, or activated does not vacate the office held, but the appropriate authority may appoint a replacement to serve as temporary acting officer as provided by this section if the elected or appointed officer will be on active duty for longer than 30 days.
(b) For an officer other than a member of the legislature, the authority who has the power to appoint a person to fill a vacancy in that office may appoint a temporary acting officer. If a vacancy would normally be filled by special election, the governor may appoint the temporary acting officer for a state or district office, and the governing body of a political subdivision may appoint the temporary acting officer for an office of that political subdivision.
(c) For an officer who is a member of the legislature, the member of the legislature shall select a person to serve as the temporary acting representative or senator, subject to approval of the selection by a majority vote of the appropriate house of the legislature. The temporary acting representative or senator must be:
(1) a member of the same political party as the member being temporarily replaced; and
(2) qualified for office under § 6, Article III, of this constitution for a senator, or § 7, Article III, of this constitution for a representative.
(d) The officer who is temporarily replaced under this section may recommend to the appropriate appointing authority the name of a person to temporarily fill the office.
(e) The appropriate authority shall appoint the temporary acting officer to begin service on the date specified in writing by the officer being temporarily replaced as the date the officer will enter active military service.
(f) A temporary acting officer has all the powers, privileges, and duties of the office and is entitled to the same compensation, payable in the same manner and from the same source, as the officer who is temporarily replaced.
(g) A temporary acting officer appointed under this section shall perform the duties of office for the shorter period of:
(1) the term of the active military service of the officer who is temporarily replaced; or
(2) the term of office of the officer who is temporarily replaced.
(h) In this section, “armed forces of the United States” means the United States Army, the United States Navy, the United States Air Force, the United States Marine Corps, the United States Coast Guard, any reserve or auxiliary component of any of those services, or the National Guard.
