Whenever a district proposes to exercise the power to borrow money, or to refund indebtedness, pursuant to this chapter, the board shall adopt a preliminary resolution declaring its intention to authorize the issuance of bonds for such purpose, which resolution shall specify all of the following:

for which any of said bonds are to run.

When bonds are issued under this chapter, the preliminary resolution of the board adopted pursuant to this article shall take effect upon its adoption by the board subject to the right of referendum herein provided for.

Upon any such resolution taking effect subject to the right of referendum, pursuant to this article, the board shall cause the same to be published in the manner provided for the publication of notices. At any time within 60 days after the date of the second such publication a referendary petition, signed by voters in number equal to at least 3 percent of the total vote cast, as defined in Section 11507, demanding the submission of such resolution to a vote of the voters of the district for their assent to the issuance of the proposed bonds, may be filed with the secretary. Upon presentation to the secretary of a referendary petition, the resolution which is the subject

thereof shall be of no effect unless and until it has been assented to by the voters.

If no such referendary petition is presented within the aforesaid period of 60 days, then upon the expiration of said period, or if the proposition of issuing the bonds specified in the resolution of the board adopted pursuant to this article has been assented to by the voters, whether upon referendum or pursuant to any other provisions of this chapter, then upon such proposition having been so assented to, the resolution shall take full and final effect, and the board may proceed in accordance with the provisions of this chapter and issue bonds within the terms of the resolution.

The provisions of any resolution constituting a part of the proceedings for the issuance of any bonds under this chapter, when so declared by its terms, or by the terms of any other such resolution, shall constitute a contract between the district and the holders of such bonds, and the provisions thereof shall be enforceable by mandamus or any other appropriate suit, action or proceeding at law or in equity in any court of competent jurisdiction.

The board at any time may adopt a resolution providing for submission to the voters of the district of the proposition of assenting to any proposed action of the board in any case where such assent is required or permitted by the terms of this chapter, or in any case where the board may deem such submission to be desirable. Such resolution may provide for such submission at any specified regular district election, or at any special election. Such resolution and such election shall, except to the extent otherwise provided in this chapter, conform to the requirements of Article 1, Chapter 7, of this division. The board shall do, or cause to be done, any and all things necessary

to make such submission at the election indicated by its resolution and to determine and certify the result thereof.
