Okla. Stat. tit. 62, § 495

The Legislature expressly states that its intention when submitting to a popular vote the proposed amendment to Article 10, Section 35, Oklahoma Constitution, in Senate Joint Resolution No. 12 of the Twenty-eighth Legislature, and its interpretation thereof as to making a tax levy not to exceed five (5) mills on the dollar on the bonds issued thereunder to secure and develop industry in the event the net taxable valuation of the counties or municipalities declines subsequent to the issuance of such bonds. This interpretation will assure the investing public that principal and interest of such bonds will be paid as they come due, and will aid the marketability of such bonds.
