Probate judges must again decide whether to issue wedding licenses to gay couples after the Alabama Supreme Court ruled the state’s ban on same-sex marriage is legal, despite a federal court’s decision to the contrary.

The all-Republican court sided with a pair of conservative groups Tuesday night and ordered Alabama’s 68 probate judges to stop issuing marriage licenses to gay couples.

A previous ruling by U.S. District Judge Callie Granade that gay-marriage bans violate the U.S. Constitution does not preclude the judges from following state law, which defines marriage as between a man and a woman, the court ruled.

It was not immediately clear what effect the court’s ruling would have, or what probate judges would do after opening their doors Wednesday.
