"Legalize Gay. Repeal Prop 8 Now! "
Proposition 8, known informally as Prop 8, was a California ballot proposition and a state constitutional amendment passed in the November 2008 California state elections. The proposition was created by opponents of same-sex marriage in advance of the California Supreme Court's May 2008 appeal ruling, In re Marriage Cases, which followed the short-lived 2004 same-sex weddings controversy and found the previous ban on same-sex marriage (Proposition 22, 2000) unconstitutional. Proposition 8 was also ultimately ruled unconstitutional by a federal court (on different grounds) in 2010, although the court decision did not go into effect until June 26, 2013, following the conclusion of proponents' appeals.
