Sec. 50-g.  GENERAL OBLIGATION BONDS FOR MAINTENANCE, IMPROVEMENT, REPAIR, OR CONSTRUCTION PROJECTS AND FOR PURCHASE OF EQUIPMENT.  (a)  The legislature by general law may authorize the Texas Public Finance Authority to provide for, issue, and sell general obligation bonds of the State of Texas in an amount not to exceed $1 billion and to enter into related credit agreements.  The bonds shall be executed in the form, on the terms, and in the denominations, bear interest, and be issued in installments as prescribed by the Texas Public Finance Authority.
(b)  Proceeds from the sale of the bonds shall be deposited in a separate fund or account within the state treasury created by the comptroller of public accounts for this purpose.  Money in the separate fund or account may be used only to pay for:
(1)  maintenance, improvement, repair, or construction projects authorized by the legislature by general law or the General Appropriations Act and administered by or on behalf of the Texas Building and Procurement Commission, the Parks and Wildlife Department, the adjutant general's department, the Department of State Health Services, the Department of Aging and Disability Services, the Texas School for the Blind and Visually Impaired, the Texas Youth Commission, the Texas Historical Commission, the Texas Department of Criminal Justice, the Texas School for the Deaf, or the Department of Public Safety of the State of Texas; or
(2)  the purchase, as authorized by the legislature by general law or the General Appropriations Act, of needed equipment by or on behalf of a state agency listed in Subdivision (1) of this subsection.
(c)  The maximum net effective interest rate to be borne by bonds issued under this section may be set by general law.
(d)  While any of the bonds or interest on the bonds authorized by this section is outstanding and unpaid, from the first money coming into the state treasury in each fiscal year not otherwise appropriated by this constitution, an amount sufficient to pay the principal and interest on bonds that mature or become due during the fiscal year and to make payments that become due under a related credit agreement during the fiscal year is appropriated, less the amount in the sinking fund at the close of the previous fiscal year.
(e)  Bonds issued under this section, after approval by the attorney general, registration by the comptroller of public accounts, and delivery to the purchasers, are incontestable and are general obligations of the State of Texas under this constitution.
