(1) The legislative power of the state shall be vested in the general assembly consisting of a senate and house of representatives, both to be elected by the people, but the people reserve to themselves the power to propose laws and amendments to the constitution and to enact or reject the same at the polls independent of the general assembly and also reserve power at their own option to approve or reject at the polls any act or item, section, or part of any act of the general assembly.
(2) The first power hereby reserved by the people is the initiative, and signatures by registered electors in an amount equal to at least five percent of the total number of votes cast for all candidates for the office of secretary of state at the previous general election shall be required to propose any measure by petition, and every such petition shall include the full text of the measure so proposed. Initiative petitions for state legislation and amendments to the constitution, in such form as may be prescribed pursuant to law, shall be addressed to and filed with the secretary of state at least three months before the general election at which they are to be voted upon.
(3) The second power hereby reserved is the referendum, and it may be ordered, except as to laws necessary for the immediate preservation of the public peace, health, or safety, and appropriations for the support and maintenance of the departments of state and state institutions, against any act or item, section, or part of any act of the general assembly, either by a petition signed by registered electors in an amount equal to at least five percent of the total number of votes cast for all candidates for the office of the secretary of state at the previous general election or by the general assembly. Referendum petitions, in such form as may be prescribed pursuant to law, shall be addressed to and filed with the secretary of state not more than ninety days after the final adjournment of the session of the general assembly that passed the bill on which the referendum is demanded. The filing of a referendum petition against any item, section, or part of any act shall not delay the remainder of the act from becoming operative.
(4) The veto power of the governor shall not extend to measures initiated by or referred to the people. All elections on measures initiated by or referred to the people of the state shall be held at the biennial regular general election, and all such measures shall become the law or a part of the constitution, when approved by a majority of the votes cast thereon, and not otherwise, and shall take effect from and after the date of the official declaration of the vote thereon by proclamation of the governor, but not later than thirty days after the vote has been canvassed. This section shall not be construed to deprive the general assembly of the power to enact any measure.
(5) The original draft of the text of proposed initiated constitutional amendments and initiated laws shall be submitted to the legislative research and drafting offices of the general assembly for review and comment. No later than two weeks after submission of the original draft, unless withdrawn by the proponents, the legislative research and drafting offices of the general assembly shall render their comments to the proponents of the proposed measure at a meeting open to the public, which shall be held only after full and timely notice to the public. Such a meeting shall be held prior to the fixing of a ballot title. Neither the general assembly nor its committees or agencies shall have any power to require the amendment, modification, or other alteration of the text of any such proposed measure or to establish deadlines for the submission of the original draft of the text of any proposed measure.

To each of such petitions, which may consist of one or more sheets, shall be attached an affidavit of some registered elector that each signature thereon is the signature of the person whose name it purports to be and that, to the best of the knowledge and belief of the affiant, each of the persons signing said petition was, at the time of signing, a registered elector. Such a petition so verified shall be prima facie evidence that the signatures thereon are genuine and true and that the persons signing the same are registered electors.
(7) The secretary of state shall submit all measures initiated by or referred to the people for adoption or rejection at the polls, in compliance with this section. In submitting the same and in all matters pertaining to the form of all petitions, the secretary of state and all other officers shall be guided by the general laws.
