California Code, Government Code - GOV § 67587

The commission may apply to the State Treasurer under the Districts Securities Law (Division 10 (commencing with Section 20000) of the Water Code), as such law now reads or may hereafter be amended to read, for the certification of any bonds issued by it as legal investments for savings banks and other funds, but such certification shall not be a condition precedent to the issuance of any bonds by the commission nor shall the State Treasurer have any jurisdiction over the expenditure of any proceeds of bonds certified by it.  If the State Treasurer determines that the bonds are adequately secured and that the revenues of the commission applicable to the payment thereof are, or probably will be, sufficient to pay the principal and interest on the bonds, and if the State Treasurer certifies to that effect, the bonds so certified shall be eligible as legal investments for both public and private funds in the same manner as provided in the Districts Securities Law.  The commission may issue bonds with or without such certification and shall not be precluded from issuing bonds subsequently without such certification, notwithstanding the fact that earlier issues of bonds may have been certified as legal investments.
