The Supreme Court halted same-sex marriages in Utah on Monday in the wake of a federal judge's ruling that would have made Utah the 18th state to allow same-sex marriages.

The court's unsigned order puts same-sex weddings on hold in Utah pending the final appeal of a Dec. 20 decision made by U.S. District Court Judge Robert Shelby.

Shelby found Utah's same-sex marriage ban to be unconstitutional and mandated an immediate end to Utah's law barring same-sex marriage. Same-sex couples began to get marriage licenses shortly thereafter.

In response, Utah officials requested a stay while their appeal proceeds through the judicial system. Both Shelby and the 10th Circuit Court of Appeals initially declined.
