In case the City Council shall, after rejection of the initiative bill, have passed an alternative bill dealing with the same subject, the alternative bill shall be submitted at the same election with the initiative bill. The ballot titles of both bills shall be printed on the official ballots so that a voter can express separately by making one cross (X) for each two preferences; first, as between either measure and neither, and secondly, as between one and the other. Only if a majority of all votes cast favor either bill in the first proposition, shall one of the bills so proposed be adopted. The measure adopted shall be the measure receiving the greater number of votes of the alternative measures. [Amended November 3, 1981]
