"There can be no doubt that extending the designation of marriage to same-sex couples, rather than denying it to all couples, is the equal protection remedy that is most consistent with our state's general legislative policy and preference," said the 120-page ruling.

It said that the state law's language "limiting the designation of marriage to a 'union between a man and a woman' is unconstitutional, and that the remaining statutory language must be understood as making the designation of marriage available to both opposite-sex and same-sex couples."

With the ruling, California becomes the second state to allow same-sex couples to legally wed. Massachusetts adopted the practice in 2004, and couples don't need to be state residents to wed there.¶
