On November 4th, California voters passed Proposition 8 with 52.3% in favor and 47.7% opposed (see map of results ). The proposition amended the state constitution to specify that only marriage between a man and a woman is valid or recognized in California. Voters also passed gay marriage bans in Arizona and Florida.

While Proposition 8 passed, it passed by a much smaller margin than Proposition 22 did in 2000. Proposition 22, the "Knight initiative" , was adopted by a vote of 61.4% to 38%.

Lambda Legal Defense, The American Civil Liberties Union (ACLU) and the National Center for Lesbian Rights (NCLR) have urged the California Supreme Court to invalidate Proposition 8 if it passes. The groups argue that Prop. 8 is invalid because it improperly attempts to undo the constitution's core commitment to equality and deprives the courts of their essential role of protecting the rights of minorities. According to the California Constitution, such a radical change in the way the courts and state government work cannot be decided by a simple ballot measure. The legal groups filed the writ petition on behalf of Equality California and six same-sex couples.

The California Constitution sets out two ways to alter the document that sets the most basic rules about how state government works. Through the initiative process, voters can make relatively small changes to the constitution. But any measure that would change the underlying principles of the constitution must first be approved by the legislature before being submitted to the voters.
