“Fifteen per cent of the legal voters of any municipality or county may order the referendum, or invoke the initiative upon any local measure. In municipalities the number of signatures required upon any petition shall be computed upon the total vote cast for the office of mayor at the last preceding general election; in counties upon the office of circuit clerk.”
Election. All measures initiated by the people whether for the State, county, city or town, shall be submitted only at the regular elections, either State, congressional or municipal, but referendum petitions may be referred to the people at special elections to be called by the proper official, and such special elections shall be called when fifteen per cent of the legal voters shall petition for such special election, and if the referendum is invoked as to any measure passed by a city or town council, such city or town council may order a special election.
Majority. Any measure submitted to the people as herein provided shall take effect and become a law when approved by a majority of the votes cast upon such measure, and not otherwise, and shall not be required to receive a majority of the electors voting at such election. Such measures shall be operative on and after the thirtieth day after the election at which it is approved, unless otherwise specified in the Act.
Self-Executing. This section shall be self-executing, and all its provisions shall be treated as mandatory, but laws may be enacted to facilitate its operation. No legislation shall be enacted to restrict, hamper or impair the exercise of the rights herein reserved to the people.
