WASHINGTON (CNN) -- Marriage licenses for same-sex couples in Utah can no longer be issued, after the Supreme Court on Monday ruled in favor of the state's request to temporarily block the impact of a federal judge's recent ruling striking down as unconstitutional a ban on gays and lesbians from legal wedlock.
U.S. District Court Judge Robert Shelby said in December the state's law "conflicts with the United States Constitution's guarantees of equal protection and due process under the law."
The issue on enforcement is tricky since hundreds of marriage licenses have already been issued by some Utah counties in the nearly two weeks since the decision was announced.
Voters there approved a law banning same-sex marriage in 2004.
Monday's action from the high court on the enforcement question is temporary and does not offer the final word on the constitutionality of the state's ban on same-sex marriage.
A Denver-based federal appeals court will take up the larger issues on an expedited basis in coming weeks, but in the meantime has allowed those marriages to continue.
The state argued last week in its high court appeal that "as a result of the district court's injunction, numerous same-sex marriages are now occurring every day in Utah. And each one is an affront... to the interests of the states and its citizens in being able to define marriage through ordinary democratic channels."
The request was presented to Justice Sonia Sotomayor, who asked all her colleagues to weigh in. Monday's order had no noted dissents and can enforced immediately.
Utah Gov. Gary Herbert (R) had criticized Judge Shelby's ruling, calling him "an activist federal judge."
