are two types of initiatives in Washington. Initiatives to the People are placed on the ballot and, if passed, become law. These initiatives require a number of signatures equal to or greater than eight percent of the votes cast in the previous state gubernatorial race. The signatures must be gathered over a period of six months. Initiatives to the Legislature are first submitted to the Washington Legislature for consideration. These initiatives require a number of signatures equal to or greater than eight percent of the votes cast in the previous state gubernatorial race. The signatures must be gathered over a period of ten months. If the legislature passes the initiative, it is enacted into law. If the legislature rejects the initiative, it is placed on the ballot for a vote of the people. If the legislature passes an alternative version, both the original and modified version will appear on the ballot. Referendums There are two types of referendums in Washington. Referendum measures are laws that have been passed by the legislature and are up for recall. These referendums require a number of signatures equal to or greater than six percent of the votes cast in the previous state gubernatorial race. Referendum bills are proposed laws that are placed on the ballot by the legislature. If passed by a public vote, they become law. Legislatively referred constitutional amendments Legislatively referred constitutional amendments are changes to the Washington State Constitution which have been approved by the legislature but require approval from the people. They require a two-thirds vote in the state legislature before being placed on the ballot. 1800s 1898 1900–1949 1900 1904 1906 1908 1910 1912 1914 1916 1918 1920 1922 1924 1926 1928 1930 1932 1934 1936 1938 1940 1942 1944 1946 1948 1950–1999 1950 1952 1954 1956 1958 1960 1962 1964 1966 1968 1970 1972 1973 1974 1975 1976 1977 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000–present 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2018 2019 2020 See also Law of Washington (state) Notes References External links Washington State Secretary of State: Elections: Initiatives Washington (state) law Ballot measures Washington ballot measures
