California Code, Government Code - GOV § 34453

At an election the voters shall vote first on the question “Shall a charter commission be elected to propose a new charter?” and, secondly, for the candidates of the office of charter commissioner. If the first question receives a majority of the votes of the qualified voters voting thereon at the election, the 15 candidates for the office of charter commissioner receiving the highest number of votes shall forthwith organize as a charter commission. However, if the first question receives less than a majority of the votes of the qualified voters voting thereon at the election no charter commission shall be deemed to have been elected.
