Cal. Gov. Code § 50623
At the time fixed for the hearing or to which it may be continued, the legislative body shall hear and pass upon the proposal and any objections which may be filed to the inclusion of any property within the proposed annexation. The legislative body, by ordinance, may determine that the territory or any part thereof will be benefited by annexation to the district and may order that the boundaries of the district be altered to include the benefited territory.
If at the hearing it appears that owners of more than one-half of the real property within the area proposed to be annexed and subject to assessment have made objection in writing to the annexation, and protests are not withdrawn so as to reduce the number of protests to less than a majority, the legislative body, by resolution entered upon its minutes, shall so find. Thereafter the legislative body shall not proceed further, and the proceeding is terminated.
