A federal appeals court says a gay couple's lawsuit seeking damages from a Kentucky county clerk who refused to issue them a marriage license can proceed. The ruling revives an issue that pulled the state into the center of a national debate over same-sex marriages following a historic Supreme Court ruling.

David Ermold and David Moore tried to get a marriage license in Rowan County, Kentucky, in June 2015 after the U.S. Supreme Court ruled same-sex marriage bans were unconstitutional. But Kim Davis, the county clerk, refused to issue them a license because she said it violated her religious beliefs.

Ermold and Moore sued, along with several other couples. Davis lost, and spent five days in jail for refusing to follow a court order. The dispute thrust the embattled clerk into the national limelight and prompted same-sex marriage opponents across the country to rally behind her. A Republican congressman from Ohio gave her a ticket to former President Barack Obama's State of the Union address. And she met with Pope Francis in Washington, although that encounter quickly sent the Vatican scrambling to distance itself from the controversy.

Davis has since changed her party affiliation to Republican, saying the Democratic Party had abandoned her. Ermold and Moore want Davis to pay damages for the emotional distress caused by her refusal to issue them a license. Ermold and Moore were not the first couple to be denied a license. But they filmed their rejection and uploaded it to YouTube, which has been viewed more than 1.8 million times.

Liberty Counsel, a Florida-based law firm specializing in religious-liberty issues, has represented Davis throughout the case. The firm also represents former Alabama Supreme Court Chief Justice Roy Moore, who ordered state probate judges to continue to enforce that state's ban on same-sex marriage despite the U.S. Supreme Court ruling. Moore was removed from his post because of his order. He is now running for U.S. Senate.
