Gov. Arnold Schwarzenegger vetoed another gay marriage bill, saying voters and California's state Supreme Court, not lawmakers, should decide the issue.
The Republican governor on Friday turned down a measure by Assemblyman Mark Leno that would have defined marriage as a union between two people, not just a man and a woman. Schwarzenegger vetoed a similar bill from Leno, a San Francisco Democrat, in 2005 and has said he would veto all such bills.
The California Supreme Court is likely to rule next year on whether the state's voter-approved ban on gay marriage violates the constitution.
Schwarzenegger said in his veto message that Californians "should not be discriminated against based upon their sexual orientation." He said he supports state laws that give domestic partners many of the rights and responsibilities of marriage.
