California Code, Education Code - EDC § 16327

No payment of funds may be made pursuant to an apportionment unless the district holds an election at which the electorate of the district approve the acceptance, expenditure, and repayment of at least the amount apportioned pursuant to this article. The election may be held prior to or subsequent to an apportionment. If the electors voting at the election fail to approve the proposition by the same majority required at a district bond election, within nine months from the date of the apportionment, the apportionment and the board's approval of the application become null and void.

Notwithstanding the foregoing, an election held prior to the effective date of Article 9 (commencing with Section 16310) of this chapter, pursuant to Section 16058, is valid for the purposes of the foregoing paragraph, provided that the district is not otherwise eligible to receive apportionments under Article 1 (commencing with Section 16000), Article 2 (commencing with Section 16150), and Article 3 (commencing with Section 16190) of this chapter.
