NEW YORK – A divided federal appeals court in Manhattan struck down the Defense of Marriage Act Thursday as unconstitutional, joining an appeals court in Boston in rejecting the law that defines marriage as between a man and a woman. The Supreme Court is expected to take up the case in the next year.

The 2nd U.S. Circuit Court of Appeals issued its 2-to-1 ruling only weeks after hearing arguments on a lower court judge’s findings that the 1996 law was unconstitutional.

The majority opinion written by Judge Dennis Jacobs rejected a section of the law that says “marriage” only means a legal union between one man and one woman as husband and wife and that the word “spouse” refers only to a person of the opposite sex who is a husband or a wife. A federal appeals court in Boston earlier this year also found it unconstitutional.

The issue is expected to be decided by the Supreme Court. The decision came less than a month after the court heard arguments on Sept. 27.

Lawyer Paul Clement, who had argued in support of the law on behalf of the Bipartisan Legal Advisory Group of the House of Representatives, was traveling and did not immediately return a message for comment.

James Esseks, an attorney for the American Civil Liberties Union, called the ruling “a watershed moment in the legal movement for lesbian and gay rights.”
