California Code, Education Code - EDC § 35756.5

In the case of the transfer of territory from one district to another, if the transfer is opposed by the governing boards of one or more of the districts affected with an average daily attendance of 900 or less, the territory in which the election is held shall include the entire territory of the districts opposing the transfer.  Each district with an average daily attendance of 900 or less which is included in an election because of the objection of its governing board to the transfer shall bear the additional cost of holding the election in that portion of its territory not otherwise included in the election.  When a majority of the votes cast in the school district opposing the transfer and a majority of the votes cast in the entire territory in which the election is held are in favor of the reorganization, the proposal carries.
