Nashville’s Fox News affiliate reports:

Eleven Christian ministers and the Tennessee Independent Baptists for Religious Liberty (TIBRL) are challenging the legality of marriage certificates issued to same-sex couples.

The group filed a Declaratory Order with the Tennessee Department of Health on Thursday, arguing while the state is following a federal order allowing same-sex couples to wed in the state, there is nothing in the Tennessee Constitution which defines marriage as anything other than that between a woman and a man.

In a statement release by The Family Action Council of Tennessee’s Constitutional Government Defense Fund (FACT), which is representing the case, FACT says the “state’s definition of marriage implicates the civil rights of the ministers in regard to the liberty of conscience guaranteed to them under the Tennessee Constitution.”

Tennessee’s FACT has been battling to have Obergefelldeclared void since the Supreme Court issued its landmark ruling in 2015.
