Supreme Court Justice Anthony Kennedy on Wednesday set a Monday deadline for litigants to file responses in an attempt to stay 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.

After being turned down by district and appellate courts, the National Organization for Marriage (NOM), the nation's most vociferous opponent of marriage equality, asked Justice Kennedy, who has jurisdiction over Oregon, to stay McShane's ruling so it may pursue a motion before the Ninth Circuit Court of Appeals in San Francisco to intervene in the case.

NOM argued in its appeal to Kennedy 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.”

Kennedy, who may act on his own or refer the matter to the full court, asked for responses to be filed by 1PM Monday.
