The National Organization for Marriage (NOM) has asked the U.S. Supreme Court to put on hold a federal court's order striking down Oregon's ban on gay marriage.

On Monday, May 19, U.S. District Judge Michael McShane declared Oregon's 2004 voter-approved constitutional amendment limiting marriage to heterosexual couples invalid.

The state, which sided with plaintiffs in the case, immediately implemented McShane's order, making Oregon the 18th state to allow gay couples to marry.

McShane denied NOM's last minute request to intervene in the case, and the Ninth Circuit Court of Appeals in San Francisco denied NOM's request to stay proceedings in the case or stay the ruling.

On Monday, NOM announced it was taking its request to the highest court in the land, asking Justice Anthony Kennedy to stay McShane's ruling so it may pursue a motion before the appellate court to intervene in the case.

“This case is an ugly spectacle of the state refusing to defend the sovereign act of its voters to define marriage as the union of one man and one woman and instead working jointly with the plaintiffs to redefine marriage,” said NOM Chairman John Eastman.

NOM said that without the ban many of its members in Oregon “will suffer particular harm,” including “a county clerk and several members of the wedding industry who will suffer material harm if the ruling is implemented.”

Justice Kennedy may elect to act on his own or he could refer NOM's request to the full court.
