Idaho Const. art. III, § 1

The legislative power of the state shall be vested in a senate and house of representatives. The enacting clause of every bill shall be as follows: "Be it enacted by the Legislature of the State of Idaho." The people reserve to themselves the power to approve or reject at the polls any act or measure passed by the legislature. This power is known as the referendum, and legal voters may, under such conditions and in such manner as may be provided by acts of the legislature, demand a referendum vote on any act or measure passed by the legislature and cause the same to be submitted to a vote of the people for their approval or rejection. The people reserve to themselves the power to propose laws, and enact the same at the polls independent of the legislature. This power is known as the initiative, and legal voters may, under such conditions and in such manner as may be provided by acts of the legislature, initiate any desired legislation and cause the same to be submitted to the vote of the people at a general election for their approval or rejection.
