Texas Local Government Code - LOC GOV'T § 271.050. Sale of Certificates

(a) The governing body may sell for cash any certificates authorized to be issued for one or more purposes described by Section 271.056.

(b) The proceeds may be used only for the purposes for which the certificates were authorized and issued. The proceeds may be used to pay for work done by employees of the issuer that are hired for the specific purpose of performing work on the project. The proceeds may be used to pay for work done by other employees of the issuer only if the issuer incurs equivalent or greater costs to replace the normal work that would have otherwise been performed by the employees. The proceeds may not be used to reimburse the issuer for costs that are determined to be indirect costs under generally accepted accounting principles. Any accrued interest received must be deposited in the interest and sinking fund established for the payment of the certificates.

(c) A certified copy of the proceedings relating to the authorization of the certificates must be submitted to the attorney general and must be approved by the attorney general as having been authorized in accordance with this subchapter. The attorney general shall examine the proceedings relating to the authorization of the certificates. Subtitles A and C, Title 9, Government Code, and Chapter 618, Government Code, govern the execution, approval, registration, and validity of the certificates. After registration of the certificates by the comptroller, the certificates are incontestable for any cause.
