The Supreme Court is debating taking up a case challenging the decade-old decision that legalized same-sex marriage in the United States.

The deliberations on Friday, Nov. 7, were closed-door, but the court could announce its decision to take up the case as early as Monday.

The case centers on former Kentucky county clerk Kim Davis, who who appealed to the high court after she was ordered to pay a gay couple $100,000 for refusing to marry them in 2015. She argued that presiding over the marriage would violate her religious beliefs.

Davis, who served as clerk in Rowan County at the time, drew international attention when she refused to issue a marriage license to David Ermold and David Moore in the wake of the court's ruling that made same-sex marriage legal in all 50 states. That case was known as Obergefell v. Hodges.
