Citing a 1948 California Supreme Court decision that overturned a ban on interracial marriages, the justices struck down the state's 1977 one-man, one-woman marriage law, as well as a similar, voter-approved law that passed with 61 percent in 2000.

The chief justice was joined by Justices Joyce Kennard and Kathryn Werdegar, all three of whom were appointed by Republican governors, and Justice Carlos Moreno, the only member of the court appointed by a Democrat.

In a dissent, Justice Marvin Baxter agreed with many arguments of the majority but said that the court overstepped its authority and that changes to marriage laws should be decided by the voters. Justices Ming Chin and Carol Corrigan also dissented.

California's secretary of state is expected to rule by the end of June whether the sponsors gathered enough signatures to put the gay-marriage amendment on the ballot.

Republican Gov. Arnold Schwarzenegger, who has twice vetoed legislation that would have granted marriage to same-sex couples, said in a statement that he respected the court's decision and "will not support an amendment to the constitution that would overturn this state Supreme Court ruling."
