The California Supreme Court today ruled that it is unconstitutional to restrict marriage to opposite-sex couples in the state.
The 4-3 opinion takes effect in 30 days, and will only face one serious challenge: a constitutional amendment on the ballot this November. And Governor Schwarzenegger, who vetoed a bill to legalize same sex marriage, has said that he will oppose the ballot initiative.
From the majority opinion, authored by the Chief Justice of the State Supreme Court:
...we cannot find that retention of the traditional definition of marriage constitutes a compelling state interest. Accordingly, we conclude that to the extent the current California statutory provisions limit marriage to opposite-sex couples, these statutes are unconstitutional.I cannot say it any better than that.
