Cal. Sts. & High. Code § 1176

For the purposes of this election, the board shall establish, by order, one or more precincts and appoint three judges for each precinct to conduct the election. The election shall be conducted as nearly as practicable in conformity with the general election laws, but no particular form of ballot need be used. To the right of or below the question on the ballot, the words “Yes” and “No” shall be printed on separate lines, with voting targets. An informality in conducting the election shall not invalidate the election if it was otherwise fairly conducted.
