A judge ruled South Dakota's gay marriage ban unconstitutional on Monday.
U.S. District Court Judge Karen E. Schreier wrote that the plaintiffs in the case "have a fundamental right to marry."
"South Dakota law deprives them of that right solely because they are same-sex couples and without sufficient justification," Schreier wrote.
The decision is stayed pending a possible appeal to the Eighth Circuit Court of Appeals.
