(2) The general assembly shall provide by statute procedures under which the registered electors of any proposed or existing city and county, city, or town may adopt, amend, and repeal a municipal home rule charter. Action to initiate home rule shall be by petition, signed by not less than five percent of the registered electors of the proposed or existing city and county, city, or town, or by proper ordinance by the city council or board of trustees of a town, submitting the question of the adoption of a municipal home rule charter to the registered electors of the city and county, city, or town. No municipal home rule charter, amendment thereto, or repeal thereof, shall become effective until approved by a majority of the registered electors of such city and county, city, or town voting thereon. A new city or town may acquire home rule status at the time of its incorporation.
(3) The provisions of this article as they existed prior to the effective date of this section, as they relate to procedures for the initial adoption of home rule charters and for the amendment of existing home rule charters, shall continue to apply until superseded by statute.
(4) It is the purpose of this section to afford to the people of all cities, cities and counties, and towns the right to home rule regardless of population, period of incorporation, or other limitation, and for this purpose this section shall be self-executing. It is the further purpose of this section to facilitate adoption and amendment of home rule through such procedures as may hereafter be enacted by the general assembly.
