DENVER – The Utah governor's office said Wednesday that the state would not recognize more than 1,000 same-sex marriages performed over the past two weeks as it appealed a legal ruling that had overturned the state's ban on such unions.

The decision came two days after the U.S. Supreme Court issued a stay in the case, blocking any same-sex marriages in Utah and effectively reinstating a disputed law that limits marriages across the state to between one man and one woman. "The original laws governing marriage in Utah return to effect pending final resolution," Derek Miller, the chief of staff to Gov. Gary Herbert, wrote to state officials. "It is important to understand that those laws include not only a prohibition of performing same-sex marriages but also recognizing same-sex marriages."

The decision could have an immediate effect on hundreds of newly married gay couples who had been planning to file joint tax returns this year, who had applied to add their spouses to their health insurance plans, or who had taken steps to legally adopt their children.
