The basicsWhat it would do: amend the state Constitution to define marriage as only between a man and a woman.
Main arguments in favor: Eight years ago, California voters passed Proposition 22, which defined marriage as between a man and a woman, by more than 60%. Proponents say the will of the people was overturned by the California Supreme Court, which allowed same-sex marriage earlier this year. This undermines the value of marriage, backers say.
Main arguments against: Foes argue that people should not be treated differently under the law because of their sexual orientation. Gays and lesbians should keep the right to marry like everyone else, say opponents.
