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. The ballots shall contain the words “Tax—Yes” and “Tax—No”. No informality in conducting the election shall invalidate the election if it was otherwise fairly conducted.
