The state Supreme Court reinstated Georgia's constitutional ban on gay marriage Thursday, just hours after New York's highest court upheld that state's gay-marriage ban.

The Georgia Supreme Court, reversing a lower court judge's ruling, decided unanimously that the ban did not violate the state's single-subject rule for ballot measures. Superior Court Judge Constance Russell of Fulton County had ruled that it did.

Seventy-six percent of Georgia voters approved the ban when it was on the ballot in 2004.

Lawyers for the plaintiffs in the case had argued that the ballot language was misleading. The ballot measure asked voters to decide on allowing both same-sex marriage and civil unions, which Russell determined were separate issues about which many people have different opinions.

State officials argued that Georgians knew what they were voting on when they overwhelmingly approved the ballot measure.
