A Kentucky county clerk is being sued for refusing to issue marriage licenses following the landmark Supreme Court ruling that legalized same-sex unions across the nation.

As the Associated Press stated, Kim Davis, an employee of rural Rowan County, is no longer giving out licenses to couples -- gay or straight -- who wish to wed, which is a move the American Civil Liberties Union (ACLU) of Kentucky deems illegal. The civil-right organization filed its lawsuit on behalf of two heterosexual and two same-sex couples, whom Davis' office had turned away last week.

The clerk claims that her religious beliefs keep her from being able to comply with the Supreme Court's Obergefell vs. Hodges decision and is among a handful of judges and clerks across the South who have defied the Court's order, Fox News noted.

With her move, Davis is also defying Kentucky Gov. Steve Beshear, who has ordered all clerks to follow the newly established law of the land. The state's attorney general, Jack Conway, has warned that employees who fail to do so might open themselves up to civil liability.

Dan Canon, one of the lawyers who representing the four couples suing Davis, told the (Louisville, Kentucky) Courier-Journal that his clients' 14th Amendment rights are being violated as a result of Davis' refusal to issue them marriage licenses.

"We certainly respect the religious beliefs and whatever conscientious choices these clerks make, but it can't infringe on their job duties and it can't infringe on the constitutional rights of the citizens that they're there to serve," Canon argued.

Casey Davis, the Republican county clerk of Kentucky's Casey County, meanwhile, told MSNBC that the state's Democratic governor should provide "some sort of relief" for clerks who object to obeying the Supreme Court's ruling on moral grounds, the newspaper noted.

"I did not take an oath that said I would lay my personal feelings down to do this job nor will I ever do that," the clerk argued.
