Article III, Section 18 of the Texas Constitution
As amended November 5, 1968:
No Senator or Representative shall, during the term for which he was elected, be eligible to (1) any civil office of profit under this State which shall have been created, or the emoluments of which may have been increased, during such term, or (2) any office or place, the appointment to which may be made, in whole or in part, by either branch of the Legislature; provided, however, the fact that the term of office of Senators and Representatives does not end precisely on the last day of December but extends a few days into January of the succeeding year shall be considered as de minimis, and the ineligibility herein created shall terminate on the last day in December of the last full calendar year of the term for which he was elected. No member of either House shall vote for any other member for any office whatever, which may be filled by a vote of the Legislature, except in such cases as are in this Constitution provided, nor shall any member of the Legislature be interested, either directly or indirectly, in any contract with the State, or any county thereof, authorized by any law passed during the term for which he was elected.
Article IV, Section 17(b) provides: "An increase in the emoluments of the office of Lieutenant Governor does not make a member of the Legislature ineligible to serve in the office of Lieutenant Governor."

Baum, 452 S.W.2d 699, 705 (Tex. 1970) ("Our analysis of the cited cases from other jurisdictions indicates a total lack of unanimity of thought as to the wisdom of nullifying the constitutional proscriptions with which we are dealing, as well as a lack of unanimity of reasons for their nulification. . . . If Sec. 18, Art. III, has outlived its usefulness and there is no longer need for the proscriptions there provided, as some of the courts of other states have indicated, the Constitution itself prescribes the remedy through a constitutional amendment submitted to and adopted by the people.")
