Tex. Education Code § 54.532

(a) The board of regents of The University of Texas System may levy a student union fee of not less than $20 or more than $150 for each semester or summer session, assessed in proportion to the number of credit hours for which a student registers, for the sole purpose of financing, operating, maintaining, and improving a student union building for The University of Texas at San Antonio. This fee may be levied in addition to any other use or service fee.

(b) The fees collected under Subsection (a) of this section shall be deposited to an account known as The University of Texas at San Antonio University Center Fee Account and shall be placed under the control of and subject to the order of the university center advisory committee. The committee shall annually submit to the president of The University of Texas at San Antonio a complete and itemized budget to be accompanied by a full and complete report of all activities conducted during the past year and all expenditures made incident to those activities. The president shall submit the budget to the board of regents as part of the institutional budget. The board of regents shall make such changes in the budget as it deems necessary before approving the budget. The board shall then levy the fees, within the limits fixed in this section, in such amounts as will be sufficient to meet the budgetary needs of the student union building.

(c) The board may not increase the amount of the student union fee in any academic year unless the amount of the increase is approved by a majority of the students voting in an election held for that purpose and by a majority of the student government of the institution.
