If a majority of the voters voting on a proposed initiative ordinance shall vote in favor thereof, it shall thereupon be an ordinance of the city. A referred ordinance which is not approved by a majority of the voters voting thereon shall thereupon be deemed repealed. If the conflicting ordinances are approved by the voters at the same election, the one receiving the greatest number of affirmative votes shall prevail to the extent of such conflict.
Initiative and referendum ordinances adopted or approved by the voters shall be published, and may be amended or repealed by the Council, as in the case of other ordinances.
