The initiative and referendum were written into the Idaho Constitution by amendments in 1912. They were policies of the Populist wave of that era. It took the Idaho legislature 21 years to implement those constitutional provisions. The laws setting up the mechanics by which the people could initiate a law, or refer a law written by the legislature to the people for approval or rejection, were enacted by the 1933 legislature.
The right of initiative and referendum is found in Article III, Section 1 of the Idaho Constitution. Title 34, Chapter 18 contains the statutory procedures pertaining to the initiative and referendum.
