when did oregon becomes first state to pass initiative referendum laws
List of Oregon ballot measures In Oregon, the initiative and referendum process dates back to 1902, when the efforts of the Direct Legislation League prompted amending the Oregon Constitution for the first time since 1859. The process of initiative and referendum became nationally known as the Oregon System.[1][2]
Referendums by country There is no provision for the holding of referendums at the federal level in the United States, which the Constitution does not provide for. A constitutional amendment would be required to allow it. However, the constitutions of 24 states (principally in the West, but also in Eastern states like Massachusetts) and many local and city governments provide for referendums and citizen's initiatives. Such state-level referendums, as an example, have resulted in the limitation of property taxes as with California's Proposition 13 and Massachusetts' Proposition 2½ in the late 20th century.
